Articles 10 to 13 of the U.S.-Italy tax treaty cap the tax the source country may charge, at 5% or 15% on dividends, 10% on interest, and zero to 8% on royalties, and they hand gains on securities to the country where the seller lives. For a U.S. citizen living in Italy those caps describe someone else's result. The saving clause keeps full U.S. tax on the citizen, Italy charges its own 26% flat tax as the country of residence, and because the credit for that flat tax is capped by the treaty and stranded by the credit limitation, the two can stack. The source of the asset, not the treaty rate, is what decides whether you are taxed once or twice.
This page takes the investment income part of our complete guide to the U.S.-Italy tax treaty and answers it on its own, in the order the money moves: the treaty rates first, then the Italian rules that sit on top of them, then two worked illustrations of the same investor holding U.S. and non-U.S. shares. Portfolio source composition is the item that is cheapest to fix before the move and most expensive to fix after it, which is the main reason a pre-move tax assessment starts with the brokerage statement.
Why is the treaty rate not the rate you pay?
One piece of background sits under everything below, so it is worth stating first. Italy collects its flat taxes on investment income as a substitute tax at the source, and the income never enters the ordinary Italian return. The Agenzia delle Entrate gives no Italian credit for the U.S. tax on such income, because its credit rules require the income to enter the ordinary return and substitute-taxed income never does. On the U.S. side the credit for the Italian tax exists but is capped: the treaty lets the United States keep its source-rate slice of a U.S.-source dividend or interest payment, and whatever the cap leaves over is stranded by the credit limitation. That is the creditability problem, and it is where the real double tax lives; the treaty tie-breaker and saving clause guide works through it in full. Every rate in this page has to be read against it.
What rates does the treaty set on dividends, interest, royalties, and gains?
Investment income (Articles 10 to 13)
This is where the rates live, and where the saving clause does the most quiet damage.
Dividends carry two source caps. The rate is 5% where the beneficial owner is a company that has held at least 25% of the paying company's voting stock for the twelve months ending on the dividend's declaration, and 15% in every other case.1 An individual investor essentially never reaches the 5% rate, since it requires a corporate owner, so the figure that matters to a private American shareholder is 15%. Note what 15% is: a cap on U.S. withholding at source, not the tax Italy charges. Italy taxes the dividend at its own 26% flat rate. There is a 0% category, but it is reserved for qualified governmental entities holding under a quarter of the payer, not for pension funds, which receive no dividend exemption under this treaty. The article also blocks the use of U.S. regulated investment companies and real estate investment trusts to manufacture low-rate dividends, so a fund dividend never gets the 5% rate and a real estate investment trust dividend often defaults to the full statutory rate.
For a U.S. citizen the 15% cap is mostly theoretical, because the saving clause keeps full U.S. tax on the citizen's U.S.-source dividends. What the cap really does is set the ceiling for the credit. The trouble starts when Italy taxes the same dividend at its 26% flat tax. That flat tax is not an ordinary withholding; it is a substitute tax taken at the source that never appears on the rest of the return. Because it never enters the ordinary return, the AdE gives no Italian credit against it, even though Italy's Supreme Court has twice sided with taxpayers that the credit is due.a This is the creditability problem set out above, seen from the dividend side. The practical result is that an American holding U.S. equities in Italy can pay U.S. tax and a 26% Italian tax whose U.S. credit is capped on the same dollars, for a combined burden well above the headline Italian rate. You end up sandwiched between the two systems. This is the single most under-appreciated cost of moving a U.S.-heavy portfolio to Italy without restructuring it first.2 There is a further wrinkle worth knowing: if you elect Italy's flat final tax on the dividend, Italy will not give a credit for the U.S. tax, so how the income is reported in Italy can itself create or avoid the double charge.b
Going deeper: this is the question most readers actually have. How to invest as an American in Italy covers the mechanics of double taxation on U.S.-source investment income, the European-fund (PFIC) trap, and the portfolio architecture that fixes it.
Interest is capped at 10% at source, higher than the zero rate many newer treaties use, with exemptions for government-related interest, government-guaranteed debt, and certain trade and equipment-sale credit.3 Royalties run in three tiers: zero for copyright on literary, artistic, and scientific works, 5% for computer software and for industrial, commercial, and scientific equipment, and 8% for everything else, which includes patents, trademarks, know-how, and film and broadcast royalties.4 There is no 7% rate in the treaty in force; that figure belonged to the earlier treaty and is a common error.
Capital gains follow the ordinary international rule. Gains on real property are taxed where the property sits, and gains on securities and most other property are taxable only in the country where the seller is resident.5 For a non-citizen moving to Italy, that means a later sale of securities is Italy's to tax. For a U.S. citizen the saving clause again preserves U.S. tax, so the residence-only rule mainly sets the framework for the credit rather than removing U.S. tax. The planning consequence is consistent with the dividend point: gains on non-U.S. assets are foreign-source for U.S. purposes, which lets the relief article re-source cleanly and lets the Italian tax credit flow, while gains and income that are U.S.-source invite the saving-clause friction.
The rates at a glance
The first table is the source-country withholding caps. The second is the basic allocation for the income types individuals hold. Both describe the non-citizen baseline. For a U.S. citizen, read each line as the starting point, then apply the saving clause and the re-sourcing relief.
Source-country caps:
| Income | Treaty cap | Condition |
|---|---|---|
| Dividends, portfolio | 15% | default |
| Dividends, direct | 5% | corporate owner holds at least 25% of voting stock for 12 months |
| Dividends to a qualified governmental entity | 0% | entity holds under 25% of the payer |
| Interest, general | 10% | default |
| Interest, exempt categories | 0% | government-related, government-guaranteed, and certain trade and equipment-sale credit |
| Royalties, literary, artistic, scientific copyright | 0% | excludes software and film or broadcast |
| Royalties, software and industrial, commercial, scientific equipment | 5% | |
| Royalties, all other, including patents, trademarks, know-how, film and broadcast | 8% |
Who taxes what:
| Income type | Primary taxing right | Article |
|---|---|---|
| Real property income and gains | Country where the property sits | 6 and 13 |
| Gains on securities and other property | Country of residence only | 13 |
| Private pensions | Country of residence only | 18 |
| Social security | Country of residence of the recipient only | 18 |
| Government-service pay and pensions | Paying country, with exceptions | 19 |
| Employment income | Where exercised, with a short-stay exception | 15 |
| Other income | Country of residence | 22 |
If a rate you read somewhere else does not match this guide, check which treaty it came from. The 1984 numbers still circulate widely.
Why can Italian fund losses not offset fund gains?
Funds and the loss-offset trap
Two Italian quirks make pooled funds especially painful, and they are worth knowing before you assume a fund behaves the way it does in a U.S. account. First, Italy taxes a gain on a fund, an OICR in its terminology, which is its word for a collective investment fund, as investment income at 26%, but it books a loss on the same kind of fund in a different category, as a capital loss. The two never meet: your fund losses cannot offset your fund gains. You can be taxed on the winners while the losers sit unused and eventually expire.c Second, and more broadly, Italy separates financial income into two baskets, one for dividends and fund proceeds, another for capital gains and losses on directly held securities, and losses in the second basket cannot offset income in the first. A U.S. investor is used to netting gains and losses freely; in Italy that netting largely disappears.
Layer the U.S. side on top, where a fund is either a U.S. security the saving clause reaches or a non-U.S. fund caught by the U.S. anti-deferral rules, and pooled funds become one of the worst things a U.S. person can hold in Italy. The working rule is to hold direct shares and bonds rather than funds.

How does Italy tax an S-corporation or a pass-through LLC?
S-corporations and pass-through LLCs: the dividend that is not a dividend
For a business owner this is the sharpest version of the whole problem, and it deserves its own warning. The United States is full of pass-through entities, the S-corporation, the single-member LLC, the partnership, that are taxed on the owner's personal return as the income is earned. Italy has no such concept. It sees a company or a sole proprietorship, and nothing in between. The AdE's published position on foreign transparent entities points the same way, and JSBC reads it as reaching a U.S. S-corporation or disregarded LLC: the entity is treated as an opaque company, and what reaches the owner is treated as a foreign dividend, taxed at the 26% flat tax.d
Now the two systems are taxing different things. The United States taxes the entity's net income the year it is earned. Italy taxes the distribution the year it is paid, and calls it a dividend. The amounts do not match, the years do not match, and the character does not match, so the relief article has nothing to line up and the credit fails. On top of that, the 26% on the "dividend" is one of the substitute taxes from the section above, with the same capped credit. The result is structural double taxation, the U.S. tax on the income and then Italy's 26% on the way out, with no offset. It is worse than a heavy portfolio dividend, because it is built into how the business itself is taxed.
The treaty is no help, for a now-familiar reason: it does not address pass-through entities or the classification mismatch at all. This is a pure classification gap the convention never resolved.
The practical answer is to fix the structure before Italian residence bites, not to argue the treaty. The common routes are to convert the entity to a C-corporation, which both countries recognize as an ordinary company that pays its own tax and then pays a real dividend where the credit actually works, to wind the entity down to dormant and run the activity through an Italian partita IVA, or to take the money as employment income, where the earned-income exclusion and the impatriate discount can apply. A dormant entity with no activity Italy will disregard, which is the one case where leaving it in place is safe.

What changes if the shares are not U.S. shares?
The only variable is where the income is sourced, and it decides the whole result. Two illustrations of the same investor, same money, one portfolio built on U.S. shares and one not, are worked side by side in the complete guide.

Frequently asked questions
Does the treaty's 15% dividend rate mean Italy can only tax me at 15%?
No. The 15% is a cap on what the source country may withhold, not the rate Italy charges. Italy taxes the dividend at its own 26% flat rate as your country of residence. For a U.S. citizen the cap is largely theoretical in any case, because the saving clause lets the United States tax its own citizen at full domestic rates on U.S.-source dividends. The 5% rate is not available to a private investor at all, since it requires a corporate owner holding at least 25% of the voting stock.
Why is a U.S.-source dividend worse than a foreign one?
Because the relief machinery only works on foreign-source income. A dividend from a non-U.S. company is foreign-source for U.S. purposes, so the credit for the Italian tax flows without the saving-clause friction. A U.S.-source dividend has to be re-sourced by the relief article to produce a credit, and the treaty lets the United States keep its source-rate slice of that dividend, so the credit for Italy's flat substitute tax is capped, the excess strands, and both countries collect.
What rate does the treaty set on interest and royalties?
Interest is capped at 10% at source, with exemptions for government-related interest, government-guaranteed debt, and certain trade and equipment-sale credit. Royalties run in three tiers: zero for copyright on literary, artistic, and scientific works, 5% for computer software and for industrial, commercial, and scientific equipment, and 8% for everything else, which includes patents, trademarks, know-how, and film and broadcast royalties. The 7% figure that still circulates online belonged to the 1984 treaty and is not in the treaty in force.
Should I hold funds or individual securities in Italy?
Individual shares and bonds. Italy taxes a gain on a collective investment fund as investment income but books a loss on the same fund as a capital loss in a separate category, so fund losses cannot offset fund gains. Layer on the U.S. anti-deferral rules that penalize non-U.S. funds and the saving clause that reaches U.S. ones, and pooled funds become one of the worst things a U.S. person can hold in Italy.

Analysis notes
- Italy's Supreme Court (Corte di Cassazione) has twice recognized the credit for foreign tax on foreign-source dividends of resident individuals even where the income is taxed in Italy by a final withholding or substitute tax: Cass. 1 September 2022 no. 25698 and Cass. 16 April 2024 no. 10204, resting on the relief provision of the convention (Article 23, paragraph 3), whose denial of the credit applies only where the final tax is imposed "by request" of the recipient. The Agenzia delle Entrate has not followed those decisions in practice, there is no return field for the credit, and recovery runs through a refund claim (istanza di rimborso) and, where refused, litigation. ↩
- 1999 convention, Article 23, paragraph 3: the Italian credit is denied where the income is subjected to a final Italian withholding tax at the recipient's election. ↩
- Under Italian domestic law, proceeds realized on an OICR (collective investment fund) are taxed as investment income (redditi di capitale), while a loss on the same holding is a capital loss (minusvalenza) in the separate category of financial capital gains and losses (redditi diversi). Capital losses can offset only capital gains within that category, not dividends or fund proceeds, so gains on funds are taxed while losses on funds cannot shelter them. See the published Italian tax analysis of fund taxation and of the 26% substitute tax on dividends and capital gains. ↩
- Art. 73, paragraph 1(d) TUIR treats a foreign entity that is transparent under its own law as opaque for Italian purposes, so the resident member is taxed only on distribution. Agenzia delle Entrate Circolare 9/E of 2015, paragraph 5.1, addresses amounts distributed by such an entity and treats what reaches the Italian-resident participant as a foreign dividend, net of the foreign tax the participant paid on the imputed income. The circolare does not name U.S. S-corporations or single-member LLCs; applying it to those entities is JSBC's reading of it, not language in the document. The treaty does not address U.S. pass-through entities or the resulting classification mismatch. ↩
