Netherlands vs Belgium.

Two countries' verified rules for an early retiree, side by side. There is no winner here: a lower cost, a wealth tax and an exit tax pull in different directions, and which ones matter is yours to weigh.

Income source	Netherlands	Belgium
Selling investments	A private listed-share or fund holding sits in Box 3 rather than a sale-gain charge. The default uses a deemed return. Current relief substitutes a lower actual return.	From 1 January 2026, a private financial-asset gain generally carries 10% tax above a €10,000 annual exemption. Earlier growth is outside the new charge.
Dividends	A private dividend is not taxed separately because the shares sit in Box 3. The default uses a deemed return. Current relief substitutes a lower actual return.	A listed-share dividend normally carries 30% tax. The first €833 of ordinary dividends can be reclaimed each year, while foreign tax depends on the treaty.
Crypto	Private crypto sits in Box 3, so a sale, exchange or spend has no separate gain charge. The default uses a deemed return. Current relief substitutes a lower actual return.	From 1 January 2026, a private crypto disposal generally carries 10% capital gains tax above the €10,000 annual exemption. Qualifying private gains were exempt under the previous rule.
Pension	A foreign occupational or private pension enters the Box 1 income-tax bands. The treaty decides source-country rights and Dutch relief.	A foreign occupational or private pension enters the progressive income-tax bands at 25–50%, plus a local surcharge of up to 9%. The treaty can instead give the source country the taxing right.
Own company	An owner with at least 5% is taxed in Box 2 on dividends and a later stake sale gain. The 2026 rates are 24.5% up to €68,843 and 31% above, after company tax.	A Belgian company pays 25% company tax, or 20% on the first €100,000 for a qualifying small company. A dividend to the owner then normally carries 30% withholding tax, with narrower small-company reliefs.

The full income picture

These are the usual rules for a resident unless a case says otherwise. A new-resident rule, tax wrapper or treaty may change one case without changing the others.

Securities and funds

Annual deemed charge

A private listed-share or fund holding sits in Box 3 rather than a sale-gain charge. The default uses a deemed return. Current relief substitutes a lower actual return.

Listed shares Annual deemed charge: The sale itself is not taxable because the holding remains in Box 3. The default uses a deemed return. Current relief substitutes a lower actual return.
Fund and ETF units Annual deemed charge: Fund and ETF units are Box 3 assets, so a gain on sale is not taxed separately. The default uses a deemed return. Current relief substitutes a lower actual return.
Foreign and US listings Annual deemed charge: Foreign or US-listed shares sit in Box 3 like Dutch shares. The default uses a deemed return. Current relief substitutes a lower actual return. The treaty controls dividend withholding.
Accumulating funds and annual tax 36% x deemed return on 1-January value: Box 3 applies a default annual deemed return rather than waiting for cash or a sale. Current relief substitutes a lower actual return.

Worth checking

Box 3 still defaults to a deemed return, but current relief substitutes a lower actual return. The future system remains under reform.

Dividends

Annual deemed charge

A private dividend is not taxed separately because the shares sit in Box 3. The default uses a deemed return. Current relief substitutes a lower actual return.

Dutch company dividend Annual deemed charge: A Dutch listed company withholds 15% dividend tax. For a passive holder, it is credited against Box 3 tax, whose deemed-return default yields to a lower actual-return claim.
Foreign listed-share dividend Annual deemed charge: A foreign dividend is not taxed as a separate flow because the shares sit in Box 3. Its deemed-return default yields to lower-actual-return relief. The treaty controls source tax.
Passive or substantial holding Different rules apply: A substantial interest starts at 5%, counted with a fiscal partner and close relatives. Below that threshold, Box 3 defaults to a deemed return but allows lower-actual-return relief.
Fund or ETF distribution Box 3 value-based: A fund distribution is not taxed separately because the units sit in Box 3. The default uses a deemed return. Current relief substitutes a lower actual return.
New-resident treatment No separate rule: The Netherlands has no separate non-domicile or remittance-basis regime. The 30%/27% expat ruling reduces tax on employment income.

There is no separate rule here. Use the general foreign-income case, then check what the treaty says about the country paying the money.

Crypto

Annual deemed charge

Private crypto sits in Box 3, so a sale, exchange or spend has no separate gain charge. The default uses a deemed return. Current relief substitutes a lower actual return.

Sale for money Annual deemed charge: A private sale to fiat is not taxed separately because crypto sits in Box 3. The default uses a deemed return. Current relief substitutes a lower actual return.
Crypto-to-crypto exchange Annual deemed charge: A private crypto-to-crypto swap is not taxed separately. Box 3 defaults to a deemed return on the holding, with current relief for a lower actual return.
Spending crypto Annual deemed charge: Paying with crypto is not a separately taxable disposal for a private holder. Box 3 defaults to a deemed return, with current relief for a lower actual return.
Staking and lending Different rules apply: Passively staked or lent crypto remains in Box 3, whose deemed-return default yields to lower-actual-return relief. Organised, labour-intensive activity can instead become Box 1 income.
Mining, validation and airdrops Different rules apply: Businesslike mining or validation is Box 1 income. Casual receipts and airdrops enter Box 3, whose deemed-return default yields to lower-actual-return relief.
Private investor or business Box 3 (passive) vs box 1 (business): A passive investor is in Box 3, with a deemed-return default and lower-actual-return relief. Activity that becomes a trade instead uses progressive Box 1 tax on actual profit.
Wealth tax and departure tax Annual deemed charge: Crypto sits in Box 3 each year, with a deemed-return default and lower-actual-return relief. It is outside the separate Box 2 departure assessment.
New-resident treatment No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.

Worth checking

Box 3 still defaults to deemed return and currently permits lower-actual-return relief. Actual return includes income and value changes, including unrealised changes.

Pensions

Box 1 progressive, up to 49.50%

A foreign occupational or private pension enters the Box 1 income-tax bands. The treaty decides source-country rights and Dutch relief.

Netherlands pension Box 1 progressive, up to 49.50%: A Dutch occupational or state pension paid to a resident is Box 1 income at progressive rates. Above state-pension age, the first combined bracket is lower because its state-pension contribution no longer applies.
Foreign state or social-security pension Income-tax bands: A foreign state or social-security pension to a Dutch resident is reported in box 1. The treaty's social-security/pension articles decide whether the source country or the Netherlands taxes it.
Foreign occupational or private pension Box 1 progressive, up to 49.50%: A foreign occupational/private pension or annuity to a Dutch resident is box-1 income. Most treaties assign periodic private-pension taxation to the residence state (the Netherlands), though several modern Dutch treaties give the source state a right over large or lump-sum/low-taxed pensions.
Foreign government or civil-service pension Treaty government-service article (usually source-only): A foreign government/civil-service pension is governed by the treaty's separate government-service article. This rule typically leaves it taxable only in the paying state (with a nationality carve-out), so the Netherlands usually exempts it with progression.
Foreign pension lump sum Income-tax bands: The pension lump sum is box-1 income when it falls to a Dutch resident. Many newer Dutch treaties specifically allow the source state to tax lump-sum or non-periodic pension payments.
Special foreign-pension rule No separate rule: The Netherlands has no special or reduced regime for foreign pension income. The inbound worker facility does not create a pension rate.

If you own a company

Box 2, 24.5% or 31% (2026)

An owner with at least 5% is taxed in Box 2 on dividends and a later stake sale gain. The 2026 rates are 24.5% up to €68,843 and 31% above, after company tax.

Company profit Taxable under the ordinary rule: Dutch corporate income tax (vennootschapsbelasting) is 19% on the first €200,000 of profit and 25.8% above (2025/2026), charged at company level before any distribution. A foreign company managed from the Netherlands can become a Dutch corporate resident (see effective-management-pe).
Distribution from a Dutch company Taxable under the ordinary rule: A dividend from the owner's Dutch private company is box-2 income at 24.5% up to €68,843 then 31% (2026). The company's 15% dividend withholding tax is credited.
Distribution from a foreign company Box 2, 24.5% or 31% (2026): The rate line above gives the resident result. The rule is tested when the income is received. The treaty can change source-country tax and relief.
Foreign entity type Depends on Dutch entity-classification rules: The rate line above gives the resident result. The rule is tested when the relevant tax event occurs.
Ownership threshold 5% (with partner or close relatives): A substantial interest starts at 5% of the shares or a class, counted with a fiscal partner and close relatives. Crossing it moves dividends and gains from Box 3 to Box 2. Box 3 otherwise defaults to deemed return with lower-actual-return relief.
Sale of your company stake Taxable under the ordinary rule: A stake of at least 5% uses Box 2 at 24.5%/31% on proceeds minus acquisition price. That price is the immigration market value where a step-up was granted.
Salary or director fee Income-tax bands: The rate line above gives the resident result. The rule is tested when the income is received.
Social contributions and remuneration risk Customary-salary minimum: The owner-director customary-salary rule deems a minimum salary and hence national-insurance/box-1 exposure even if the owner tries to take only dividends. A owner-director is generally not covered by employee insurance but pays national insurance on the deemed salary.
Running the company from the Netherlands Risk of Dutch corporate residence or taxable business presence: Running a foreign company from the Netherlands can make it a Dutch tax resident (place of effective management here) or create a Dutch permanent establishment. This is the main risk for a mover who keeps operating an old company from a new Dutch home.
Controlled foreign company rules Controlled foreign companies (EU anti-avoidance) for low-taxed passive subsidiaries: The Netherlands has an EU anti-avoidance controlled foreign companies regime (from 2019) that can currently tax undistributed passive income of a controlled subsidiary in a low-tax (<9%) or listed jurisdiction. It principally targets corporate structures.
New-resident treatment No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.

Review the company and your personal position together before the move.

Interest and cash

Annual deemed charge

Interest is not taxed separately because deposits and bonds sit in Box 3. The default uses a deemed return. Current relief substitutes a lower actual return.

Netherlands bank or bond interest Annual deemed charge: Dutch bank interest is not taxed as a separate flow and carries no withholding. Box 3 uses a deemed-return default, with current relief for a lower actual return.
Foreign bank or bond interest Box 3 value-based: Overseas deposits and bonds sit in Box 3 like domestic holdings. Its deemed-return default yields to lower-actual-return relief, while the treaty controls credit for foreign tax.
Allowances and extra charges Reduced rule: The rate line above gives the resident result. The rule is tested each year.
New-resident treatment No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.

Rent

Annual deemed charge

Rent from a private investment property is not taxed separately because the property sits in Box 3. The default uses a deemed return. Current relief substitutes a lower actual return.

Property in Netherlands Annual deemed charge: A let Dutch property sits in Box 3, so the rent is not taxed separately. The deemed-return default applies to its net value unless lower-actual-return relief gives a smaller result.
Property abroad Box 3 base, then treaty exemption-with-progression: Foreign property enters the annual Box 3 calculation before treaty relief. The default uses a deemed return. Current relief substitutes a lower actual return.

There is no separate rule here. Use the general foreign-income case, then check what the treaty says about the country paying the money.

Property gains

No gain charge (main home)

A private property sale does not create a separate gain charge. An investment property remains in Box 3, whose deemed-return default yields to lower-actual-return relief.

Netherlands main home No gain charge (main home): This gain on selling the owner-occupied main home is not taxed. The home is a box-1 asset taxed only via the annual deemed rental value.
Netherlands investment or second property No separate rule: A Dutch investment-property gain is not taxed separately. Box 3 applies a deemed-return default while the property is held, with current relief for a lower actual return.
Starting value after a move No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.
New-resident treatment No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.

There is no separate rule here. Use the general foreign-income case, then check what the treaty says about the country paying the money.

Royalties

Box 1 (active) or box 3 asset (passive right)

The Netherlands has no general withholding on outbound royalties, apart from a conditional charge to low-tax related parties. Active personal creation is Box 1 income. A passive right can sit in Box 3 under deemed-return default and lower-actual-return relief.

Netherlands royalties Box 1 (active) or box 3 asset (passive right): Active exploitation of intellectual property is progressive Box 1 income. A passively held right sits in Box 3, whose deemed-return default yields to lower-actual-return relief.
Foreign royalties Different rules apply: A foreign royalty is Box 1 income when active. A passive right sits in Box 3 under deemed-return default and lower-actual-return relief. The treaty controls source-country tax.
Which rights qualify Different rules apply: Copyright, patent and licensing income can all qualify. Active exploitation uses Box 1. A passive Box 3 right uses deemed-return default and lower-actual-return relief.
Passive or active Box 3 (passive) vs box 1 (active): A passive royalty right sits in Box 3 under deemed-return default and lower-actual-return relief. Active exploitation uses progressive Box 1 tax on actual receipts.
Social contributions and value-added tax Special rule: Active licensing can attract 21% value-added tax and an income-dependent healthcare contribution. Passive Box 3 rights instead use deemed-return default and lower-actual-return relief.

If you still work

8.10%, 37.56% or 49.50% brackets, including national insurance

Employment and self-employment are progressive Box 1 income. The 2026 combined rate reaches 49.50%, while national insurance is capped.

Employment in the Netherlands 8.10%, 37.56% or 49.50% brackets, including national insurance: Dutch employment income is box-1. Combined wage-tax plus national-insurance brackets of 8.10% to €38,883, 37.56% to €78,426 and 49.50% above (2026).
Remote work for a foreign employer Income-tax bands: A resident working remotely from the Netherlands for a foreign employer is box-1 taxable on that work. The foreign employer risks creating a Dutch permanent establishment / wage-tax and social-security obligations. Check the treaty for source tax and Netherlands's relief.
Self-employment and consulting Income-tax bands: Self-employment profit is progressive Box 1 income. An income-dependent healthcare contribution of 6.10% applies up to €79,409, and entrepreneur allowances can also apply.
Director fees Income-tax bands: The rate line above gives the resident result. The rule is tested when the income is received.
New-resident worker rule Up to 30% (27% from 2027) of salary exempt, 5 years: A qualifying incoming skilled employee can receive up to 30% of salary exempt for extraterritorial costs, for a maximum of 5 years. From 1 January 2027 the maximum falls to a flat 27% and the salary norm rises to €50,436 (€38,388 for under-30 master's holders).

Worth checking

The expat ruling is being tightened repeatedly (the 2024 30/20/10 taper was withdrawn in favour of a flat 27% from 2027 with a higher salary norm).

Two terms that matter in the Netherlands

Boxes 1, 2 and 3

Box 1 covers work and pensions, while Box 2 covers a company holding of at least 5%. Box 3 defaults to a deemed return but allows current relief for a lower actual return.

Actual-return relief

A current claim route when real return is below the Box 3 deemed-return default. Actual return counts income and value changes, including unrealised changes.

Your first tax year and starting values

Two dates matter: when your new country starts taxing you, and which value it uses to work out a later gain. Check both before you move.

When residence starts: Dutch tax residence is based on the facts, including a permanent home, family and durable personal ties. There is no fixed statutory day count.
The arrival year: The year of arrival is a part-year. A migration-year return splits it into a non-resident period and a resident period.
Dual residence: If the former country still claims residence, the applicable treaty tie-breaker decides. It looks at the permanent home, centre of vital interests, habitual abode and nationality.
Listed shares and funds: Annual value system, not a normal sale basis
This asset uses the Box 3 annual-value system rather than a sale basis. The default uses a deemed return. Current relief substitutes a lower actual return.
Crypto: Annual value system, not a normal sale basis
Crypto uses the Box 3 annual-value system rather than a sale basis. The default uses a deemed return. Current relief substitutes a lower actual return.
Owner-company stake: Market value only when the conditions are met
Market value can become the new starting value only when the stated conditions are met. Otherwise the original purchase cost continues.
Property: Annual value system, not a normal sale basis
Property in Box 3 uses an annual-value system rather than a sale basis. The default uses a deemed return. Current relief substitutes a lower actual return.

Plain-language key

Withholding tax: Tax taken before the money reaches you, usually in the country where the payment comes from.
Tax credit: Tax already paid abroad can reduce the bill where you live. The reduction is usually capped at the local tax on that same income.
Original purchase cost: What you paid for the asset. A market-value reset replaces that figure with the asset's value when you move.
Income-tax bands: The income is added to your other taxable income. Higher total income can push part of it into a higher band.
Permanent establishment: A taxable business presence. Running a foreign company from your new home can create one even if the company remains registered abroad.

This gives you the starting rule, not your final bill. The country paying the money, your treaty, account, holding period, residence dates and activity can change the result.

Full income detail: Belgium

The full income picture

These are the usual rules for a resident unless a case says otherwise. A new-resident rule, tax wrapper or treaty may change one case without changing the others.

Securities and funds

10% above the €10,000 exemption (from 2026)

From 1 January 2026, a private financial-asset gain generally carries 10% tax above a €10,000 annual exemption. Earlier growth is outside the new charge.

Listed shares 10% above the €10,000 exemption (from 2026): Historic exemption reversed for gains accruing from 1 Jan 2026. A private investor's realised share gain carries tax at 10% on the amount above a €10,000 indexed annual exemption.
Fund and ETF units Different rules apply: A fund disposal can combine the 2026 financial-asset gains charge with the separate 30% charge on a qualifying fund's debt component. The fund's holdings decide whether that second rule applies.
Losses Reduced rule: The rate line above gives the resident result. The rule is tested when the asset is sold or otherwise disposed of.
Foreign and US listings Reduced rule: A resident's gain on a foreign or US-listed share carries the same 10% charge from 2026. A US-domiciled ETF can also face the separate 30% charge on its debt component.
Accumulating funds and annual tax Taxable under the ordinary rule: The rate line above gives the resident result. The rule is tested when the asset is sold or otherwise disposed of.

Worth checking

Everything here is in flux. The 10% capital gains tax only took effect 1 Jan 2026 and had no legal basis to be withheld by intermediaries in the Jan-May 2026 transitional window (taxpayers self-declare).

Dividends

30% plus tax taken abroad

A listed-share dividend normally carries 30% tax. The first €833 of ordinary dividends can be reclaimed each year, while foreign tax depends on the treaty.

Belgian company dividend Taxable under the ordinary rule: A dividend from a Belgian company carries tax at the flat 30% movable withholding deducted at source. This rule is generally the final tax with no further reporting needed.
Foreign listed-share dividend 30% plus tax taken abroad: A foreign dividend carries tax at 30% in Belgium. Domestic credit for foreign dividend withholding is generally unavailable to an individual, so source-country withholding can remain an extra cost.
EU or EEA company dividend No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.
Third-country company dividend No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.
Passive or substantial holding 30% at any listed-holding size: Listed portfolio dividends have no minority-versus-substantial split for an individual. The 30% withholding applies at any stake size.
Fund or ETF distribution Taxable under the ordinary rule: A distributing fund payment carries 30% withholding like another dividend. A qualifying fund's interest or debt component can face a separate 30% charge.
New-resident treatment No separate rule: Belgium has no separate non-domicile or remittance-basis regime. The new resident is taxed on worldwide dividends at 30% from the start of residence.

Worth checking

The €833 dividend exemption and €1,020 savings-interest exemption are indexed and move yearly. The small-company dividend relief reduced rate rises from 15% to 18% from 1 July 2026 for new contributions.

Crypto

10% above the €10,000 exemption (from 2026)

From 1 January 2026, a private crypto disposal generally carries 10% capital gains tax above the €10,000 annual exemption. Qualifying private gains were exempt under the previous rule.

Sale for money 10% above the €10,000 exemption (from 2026): From 1 Jan 2026 a private investor's sale of crypto to fiat is caught by the 10% capital gains tax on gains above the €10,000 annual exemption. A bon-pere-de-famille disposal was exempt.
Crypto-to-crypto exchange 10% (from 2026) if a taxable realisation event: The 2026 capital gains tax taxes realised gains on crypto-assets. A crypto-to-crypto swap is generally a realisation of the disposed asset.
Spending crypto No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.
Holding relief and losses Reduced rule: The rate line above gives the resident result. The rule is tested when the asset is sold or otherwise disposed of.
Staking and lending Taxable under the ordinary rule: Staking and lending rewards are taxable income on receipt at market value. Typically as movable/miscellaneous income (often cited at 30%), or as professional income (up to 50%) where the activity is a business.
Mining, validation and airdrops Taxable under the ordinary rule: Mining/validation is generally treated as a professional or miscellaneous activity. Rewards are income on receipt at market value, taxed as professional income (progressive up to 50%, plus social contributions) where it amounts to a business.
Private investor or business 10% capital gains tax (private, from 2026) or 33% (speculative) or up to 50% (professional): The tax-ruling service questionnaire (17 questions) assesses whether a holder is a prudent investor.
New-resident treatment No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.

Worth checking

Belgium's crypto position flipped in 2026. What was a genuine exempt zone for the qualifying long-term private holder is now a 10% capital gains tax zone.

Pensions

25–50% plus local surcharge

A foreign occupational or private pension enters the progressive income-tax bands at 25–50%, plus a local surcharge of up to 9%. The treaty can instead give the source country the taxing right.

Belgium pension Income-tax bands: A Belgian statutory or occupational pension uses the progressive rates. A pension-income tax reduction can materially lower the effective rate at modest incomes.
Foreign state or social-security pension Income-tax bands: A foreign state or social-security pension received by a Belgian resident is in principle taxable in Belgium as professional income. Most treaties assign social-security pensions to the paying (source) state. Check the treaty for source tax and Belgium's relief.
Foreign occupational or private pension 25–50% plus local surcharge: Many treaties assign private pensions to the residence state (Belgium). Belgium usually taxes them fully. Check the treaty for source tax and Belgium's relief.
Foreign government or civil-service pension Special rule: When the treaty assigns it to the source state, Belgium exempts it with progression. The specific treaty article governs.
Foreign pension lump sum Separate rates (about 10–20% depending on age or conditions): A Belgian occupational-pension lump sum uses separate rates rather than the progressive scale. The range is about 10–20%, depending on age and continued-work conditions.
Special foreign-pension rule No separate rule: For this case, Belgium has no special or reduced regime for foreign pension income. Foreign periodic pensions are ordinary professional income.

Worth checking

A treaty can allocate a Belgian pension differently after the recipient moves abroad. Private, state and government-service pensions do not always follow the same article.

If you own a company

30% plus tax taken abroad

A Belgian company pays 25% company tax, or 20% on the first €100,000 for a qualifying small company. A dividend to the owner then normally carries 30% withholding tax, with narrower small-company reliefs.

Company profit 25% (20% small company on first €100,000): A same-country (Belgian) company pays 25% company tax.
Distribution from a Belgian company Taxable under the ordinary rule: A dividend from the owner's Belgian company normally bears 30% withholding. Qualifying small-company shares issued for cash from 1 July 2013 can receive a reduced 15% rate, rising to 18% for new contributions from 1 July 2026. Profit routed through a liquidation reserve can instead come out at about 5 / 6.5 / 10%.
Distribution from a foreign company 30% plus tax taken abroad: The rate line above gives the resident result. The rule is tested when the income is received. The treaty can change source-country tax and relief.
Foreign entity type Special rule: The rate line above gives the resident result. The rule is tested when the relevant tax event occurs.
Ownership threshold At least 20% triggers the capital gains tax progressive substantial-holding scale (1.25–10%): For the 2026 capital gains tax. A substantial participation (holding at least 20% of the company) triggers a separate progressive scale on the gain from selling the stake.
Sale of your company stake Different rules apply: Two regimes can overlap. The ordinary 2026 gain charge is 10%, with a separate scale for a stake of at least 20%. A sale to a controlled company can instead trigger a 33% internal-gain charge.
Salary or director fee Income-tax bands: For this case, salary or director's fees are professional income taxed at the progressive 25–50% rates plus communal surcharge. A company director is self-employed for social-security purposes (contributions about 20.5% of net professional income, capped), not an employee.
Social contributions and remuneration risk Special rule: A director of a Belgian company must generally take a minimum remuneration (€45,000 or at least equal to taxable profit) for the company to keep the 20% small company rate. Failing it triggers a separate corporate levy.
Running the company from Belgium Special rule: The rate line above gives the resident result. The rule is tested each year.
Controlled foreign company rules Special rule: Belgium has EU anti-avoidance controlled foreign companies rules for corporate taxpayers, attributing certain undistributed passive income of a low-taxed controlled foreign company to the Belgian parent. Belgian control of a low-taxed foreign entity with mainly passive income.
New-resident treatment No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.

Worth checking

The July 2025 Programme Act and the 2026 reform reshaped owner-company extraction. Small-company dividend relief rises to 18% and the liquidation-reserve waiting period/rates are being harmonised.

Review the company and your personal position together before the move.

Interest and cash

30% withholding (savings accounts differ)

Interest to a resident bears the flat 30% investment withholding tax. Regulated Belgian savings-account interest is exempt on the first €1,020 then taxed at 15%.

Belgium bank or bond interest 30% withholding (savings accounts differ): Bond interest, term-deposit interest and current-account interest carry flat 30% withholding. Regulated Belgian savings accounts are the exception.
Foreign bank or bond interest Taxable under the ordinary rule: Foreign interest carries tax at 30% in Belgium (no reduced 15% savings rate for non-Belgian accounts as a rule). Many treaties reduce source interest withholding tax to zero, but that is pair-specific and Belgium gives individuals limited domestic credit.
Allowances and extra charges Reduced rule: The only interest allowance is the €1,020 regulated-savings exemption (then 15%). Ordinary interest has no allowance and no separate social levy.
New-resident treatment No separate rule: Worldwide interest taxed at 30% from the start of residence. The inbound-resident regime does not shelter investment interest.

Rent

Progressive, on cadastral income +40%

Belgian residents are taxed on rental income at progressive rates, but the base is usually a notional (cadastral) figure, not actual rent. For private (non-professional) letting the taxable base is the indexed cadastral income increased by 40%.

Property in Belgium Progressive, on cadastral income +40%: Let to a private individual for private use. Taxed on the indexed cadastral income increased by 40%, at progressive rates.
Property abroad Reduced rule: For this case, since assessment year 2022 a Belgian resident's foreign property is assigned a surrogate cadastral income and taxed on the same basis as Belgian property. In practice, the property state has the primary taxing right under the treaty.
EU or EEA property branch No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.
Rental deductions Reduced rule: For professionally-let property taxed on actual rent. A 40% lump-sum cost deduction applies (capped).

Worth checking

Private rent can be calculated from indexed cadastral income rather than the cash received. The property type and use decide whether that method applies.

Property gains

0% (main-residence exemption)

A private individual's main residence sale is exempt. A built property sold within 5 years carries tax at 16.5% (+ communal), land within 5 years at 33% (5-8 years 16.5%).

Belgium main home 0% (main-residence exemption): The gain on the sale of a Belgian main residence is exempt from personal income tax. This also requires that the seller occupied it as their main home for at least 12 months (with a short tolerance period).
Belgium investment or second property Taxable under the ordinary rule: A built investment/second property sold within 5 years of acquisition carries tax at 16.5% (+ communal surcharge) on the gain. Building land carries tax at 33% if sold within 5 years and 16.5% between 5 and 8 years.
Foreign property Reduced rule: Immovable property is normally taxable where it is situated, so a foreign property sale is taxed by the property state. Belgium exempts the gain with progression. Check the treaty for source tax and Belgium's relief.

Foreign third-country property branch No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.
Main-home conditions 0% subject to at least 12 months occupation: A property must normally have been the seller's main residence for at least 12 months before sale. A limited gap can be tolerated. For this case, it also removes the 5-year-clock charge that would otherwise apply to a quick resale.
Starting value after a move Different rules apply: The 5-year clock runs from acquisition (historic cost), with no arrival step-up. For foreign property the gain is usually treaty-exempt in Belgium regardless.

Real estate remains outside the 2026 financial-asset gains charge. The main-home exemption, holding period and rental basis follow separate property rules.

Royalties

15% qualifying copyright (else 30%)

Royalties to a resident normally carry 30% withholding. Qualifying copyright royalties can instead use a reduced 15% rate up to an indexed annual ceiling.

Belgium royalties 15% qualifying copyright (else 30%): Qualifying copyright and neighbouring-rights income is taxed at 15% after a lump-sum cost deduction, up to an indexed annual ceiling. The regime was narrowed from 2023 and does not cover every profession.
Foreign royalties Taxable under the ordinary rule: Foreign royalties carry 30% tax, or 15% when they qualify as copyright income within the ceiling. A limited foreign-tax credit can apply. The treaty controls source tax.
Which rights qualify Reduced rule: This 15% regime is specifically for copyright and neighbouring rights (authors, artists, some software historically). For this case, patent and general licensing royalties do not get the 15% movable rate and are 30% movable income or professional income.
Passive or active 15% or 30% movable vs progressive professional up to 50%: The rate line above gives the resident result. The rule is tested when the relevant tax event occurs.
Social contributions and value-added tax No safe answer yet: No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.

Worth checking

The royalties watch depends on the asset classification, source country or treaty. Recheck the stated conditions before acting.

If you still work

25–50% plus local surcharge

Employment income carries tax at progressive 25–50% rates plus a 0–9% communal surcharge, with a 13.07% uncapped employee social-security contribution. Self-employed pay about 20.5% social contributions on net income.

Employment in Belgium 25–50% plus local surcharge: Salary carries tax at the progressive 25–50% rates plus the municipal surcharge (0–9%, about 7% average), after a 13.07% uncapped employee social-security contribution and with a lump-sum professional-cost deduction. For this case, Belgium's combined tax-and-social wedge on labour is among the highest in the OECD.
Remote work for a foreign employer Income-tax bands: The resident working remotely in Belgium for a foreign employer is taxed by Belgium on that employment income (residence plus place of work), at progressive rates. The foreign employer risks creating a Belgian permanent establishment and Belgian payroll/social obligations.
Self-employment and consulting Income-tax bands: The rate line above gives the resident result. The rule is tested when the income is received.
Director fees Income-tax bands: Director's fees are a distinct treaty category that the company's state may tax. Domestically they are professional income taxed at progressive rates with self-employed social contributions.
New-resident worker rule Exempt cost allowance (30% of gross, capped) for a limited period: It targets employment income, not investment/pension income.

Two terms that matter in Belgium

Movable income

Belgium's category for dividends, interest and similar investment receipts. It usually uses withholding tax rather than the normal income-tax bands.

Genuine newcomer

A person entering Belgian tax residence without being a recent returner. That distinction controls the new arrival value for some financial assets.

Your first tax year and starting values

Two dates matter: when your new country starts taxing you, and which value it uses to work out a later gain. Check both before you move.

When residence starts: Belgian tax residence turns on domicile (real, effective residence) or the seat of wealth/family (siege de la fortune). Registration in the National Register / population register creates a rebuttable presumption of residence.
The arrival year: Belgium effectively splits the year of arrival/departure. You are taxed as a resident (worldwide income) for the part of the year you are resident and as a non-resident (Belgian-source only) for the rest.
Dual residence: If the former country still claims residence, the treaty tie-breaker decides. A retained home, family location, centre of vital interests, habitual abode and nationality can matter.
Listed shares and funds: Market value only when the conditions are met
Market value can become the new starting value only when the stated conditions are met. Otherwise the original purchase cost continues.
Crypto, Owner-company stake: No safe answer yet
No safe answer is shown for this exact case yet. Check the facts and treaty before relying on a result.
Property: Original purchase cost
The original purchase cost continues after the move. A later taxable gain can therefore include growth from before residence began.

Plain-language key

Withholding tax: Tax taken before the money reaches you, usually in the country where the payment comes from.
Tax credit: Tax already paid abroad can reduce the bill where you live. The reduction is usually capped at the local tax on that same income.
Original purchase cost: What you paid for the asset. A market-value reset replaces that figure with the asset's value when you move.
Income-tax bands: The income is added to your other taxable income. Higher total income can push part of it into a higher band.
Permanent establishment: A taxable business presence. Running a foreign company from your new home can create one even if the company remains registered abroad.

This gives you the starting rule, not your final bill. The country paying the money, your treaty, account, holding period, residence dates and activity can change the result.

Shown in

A guide, not a quote. I move your monthly spend by each country’s official price level (Eurostat and the World Bank, whole-economy, EU-27 = 100). No exchange rates, so it stays in your own currency. But averages hide rent and the city you pick, and changing country is rarely a straight swap. Read these as the right ballpark, then price the real thing.

The tax rules, in full.

Netherlands

Taxed on an assumed return, unless your real one was lower.

Box 3, the default

Investments are taxed on a deemed return: the state assumes your wealth earned a set percentage by asset class and taxes that, as the default calculation, unless you claim the actual-return relief below. For planning, the default still works like a wealth tax on investments: an annual charge the portfolio must out-earn, which raises your number.

The actual-return relief

The transitional system that runs today has a second half: report your actual return and, if it comes in lower than the deemed one, you're taxed on the real figure instead. Actual return isn't just what you sold: it counts dividends, interest and the year's change in market value, realised or not. So a genuinely bad year no longer pays the full assumed bill, while a good year still pays the deemed default.

The reform

A full shift where actual returns replace the deemed system entirely, rather than sitting beside it as relief, has been targeted for 2028, but the bill is still contested: neither the shape nor the date is settled.

Worth watching

Next signal: Prinsjesdag, September 2026, when the cabinet's promised improvements to the 2028 bill are due. The actual-return relief above is current law either way.

Belgium

The old haven, gently closed.

Wealth tax

No net wealth tax, but an annual 0.15% 'solidarity' tax applies to securities accounts worth €1 million or more. Below the million, nothing; above it, a small standing drag on the pot.

Worth watching

The new tax is young: the exemption starts indexing from 2027, and constitutional challenges are still possible. Re-check the shape before you build a plan on it.

None of this is tax or investment advice: it's education, kept deliberately at the level that survives fact-checking. Rules shift with every budget round; the specifics of your situation belong with a licensed adviser in your country. I'm happily not one.
