Where your fund lives is a fee.
Your fund's domicile, not yours. Before a dividend ever reaches your fund, a slice is taxed away, and the size of that slice is set by where the fund is based and how it's built. Put in your pot and horizon and see what the difference costs, structure by structure. I name the structures; I never tell you which to buy.
Explain it like I’m five
Your fund holds American companies. When they pay out, America keeps a slice before the money even reaches the fund, and the size of the slice depends on where the fund lives. Same companies, different address, different slice. This page shows what your fund’s address costs, in your money.

The gap, in your money

The Irish fund versus the Luxembourg one, on €100k over 30 years: same index, same pot, two fund addresses.
See it as months of your working lifeThe certain, structural slice: your fund's US dividends, taxed at each structure's documented rate before anything else happens, compounded on your pot at a steady 6% real return. US dividends only: other markets withhold too, but smaller and messier, and I don't guess. Fund-level only: what your own country then taxes you is the atlas's job. Rates and sources dated below.

The same pot, three structures
- Drag / yr
- 0.165%
- Over 30y
- €26k
An Irish-domiciled fund counts as a US-treaty resident, so the US takes the reduced treaty rate on the dividends its American holdings pay in, not the full rate it charges foreign owners by default.
- Drag / yr
- 0.33%
- Over 30y
- €51k
Luxembourg's fund companies are written out of the US treaty, so US dividends inside the fund are withheld at the full rate. The structural archetype: in practice the shelf holds almost no physical Luxembourg US-equity fund.
- Drag / yr
- 0.00%
- Over 30y
- €0
A swap tracking a qualifying broad US index isn't treated as owning the shares, so no US withholding lands on the swap leg. The swap's own spread and its counterparty risk are separate costs this rate can't show.
The fourth structure, a US-domiciled fund held directly, deliberately isn't a row: its withholding lands on you rather than inside the fund, it's sometimes creditable at home, and the paperwork rules keep it off most European brokers anyway. The guide has the honest paragraph.

The tax you never see
When an American company pays a dividend to a European fund, the United States takes a cut before the money is even inside the fund, because the fund is a foreign owner. How big a cut is the fund's paperwork, not yours: an Irish fund claims the US treaty's 15%, a Luxembourg physical fund pays the full 30%, and a swap-based fund tracking a broad US index sidesteps the dividend altogether. None of it ever appears on a statement. The only place it leaves a mark is the fund's tracking record, which is exactly where I found it.
The reading half, why these numbers exist and what they don't cover, is the withholding guide.
The withholding guide: the two layers, the receipts, the myths
The swap-based catch
The swap-based row isn't a free lunch, and I won't sell it as one. A synthetic fund holds a contract with a bank rather than the shares themselves, so the swap carries its own spread, and it adds counterparty risk: you're trusting a bank to make good on the promise. That's a real trade-off, and it's yours to weigh. I price the three structures; I don't rank them.
Checked July 2026
The three rates come from the primary texts, not summaries of them: the US–Ireland treaty, the treaty language that writes Luxembourg's fund companies out of it, and the US regulation that exempts a swap on a qualifying broad index. The fund shapes behind the presets (how American each index is, and what its holdings yield) are the index providers' and the funds' own published figures, all to the same date. One set of maths produces every figure here and on the share card, and I re-verify all of it yearly.
Nothing to sell
No affiliate links. No paywall. Nothing on this page is for sale, and no fund provider pays me to make one structure look better. The neutrality is the whole point.

Common questions
- I’ve never been charged this tax. Where is it?
- Inside the fund, which is why you’ve never seen it. When the fund’s American holdings pay their dividends, the US takes its cut before the money even lands in the fund, so no statement of yours ever shows it. The only place it leaves a mark is the fund’s tracking record: the gap between what the fund returned and what its index did. The Tracking Gap is where you can read that record, fund by fund.
- Is this the dividend tax I pay in my country?
- No. This is the layer before that one: tax taken inside the fund, set by where the fund is based, and identical for every investor holding it. What your own country then charges you is a separate layer that depends on where you live and the account you use, and that’s the Europe atlas’s job. The two stack; they’re not the same tax.
- My fund is accumulating. Doesn’t that avoid the withholding?
- No, and that myth is half the reason this tool exists. The withholding was taken inside the fund, on the dividends its holdings paid in, before the fund decided whether to reinvest or pay out. Accumulating changes what happens after: no distribution, and often different timing on your own tax. It can’t reach back and un-tax the dividend. The withholding guide takes this one apart properly.
- The swap-based row shows the smallest drag. Should I buy that?
- Not so fast, and not from me. The swap sidesteps the dividend withholding, but it carries a cost of its own (the counterparty’s spread) and a risk of its own: you’re trusting a bank to honour the contract. Whether that trade is worth it is yours to weigh. I price the structures; I don’t rank them, and the honest way to judge any real fund is its tracking record, not its label.
- Why does it only count US dividends?
- Because the American layer is the one clean enough to price honestly: one market, documented treaty rates, and most broad index funds are US-heavy anyway. Other markets withhold too, but smaller, messier and not uniform, so any figure I printed would be a guess, and I don’t guess. Treat the result as the certain slice, not the whole story.
- Where do these rates come from?
- From the treaties and the rules themselves, not from forum folklore: the US–Ireland treaty’s reduced rate for Irish funds, the treaty exclusion that leaves a Luxembourg fund on the full statutory rate, and the US rule that lets a swap on a broad index sidestep the dividend entirely. I re-verify them yearly, and the checked date is on the page. If it looks old, distrust me and check.
