Withholding Tax: Source, Rates and Treaty Relief

The concept

Withholding tax is the only tax an investor pays without noticing. Nobody calculates it or remits it for themselves: the deduction is made by the payer of the income at the moment of payment, on the full, gross amount, before the money has crossed the border. Eighty-five arrives in the account instead of a hundred — and the owner of the portfolio often learns that the tax exists after the fact, from a broker's statement.

The logic is harsh and, in its own way, elegant. A dividend, an interest payment or a royalty leaves for a non-resident, and the tax base leaves the jurisdiction with it for good: once the recipient is abroad, the source state is powerless to reach him. The moment of payment is the last point of control at which the money is still physically inside the country. So the payer is conscripted as collector: a bank or an issuer answers for someone else's tax with its own money, and its incentives are made of iron. Note that the mechanism is older than any exchange of information — the source need not even know who the recipient is, because the border does its work automatically. On how states share data today, see the CRS overview.

This works mainly on passive income. A capital gain on the sale of shares is usually released by the source country without any deduction: a different logic applies there, worked through in the article on capital gains tax.

On top of the domestic rates sits a treaty architecture. Tax treaties cut the rate at source, and on dividends an almost universal canon has settled:

• 0% — intra-group dividends on a substantial holding (in the EU, through the Parent-Subsidiary Directive);
• 5% — the "direct investor" with a stake of 10–25% of capital;
• 15% — the portfolio investor, the base case.

The currency of access to those rates is the certificate of tax residence. Without a piece of paper confirming residence in a treaty jurisdiction, the payer must withhold at the full domestic rate. The entire tax reclaim industry grew out of one simple fact: the certificates are paper, the procedures are national, and the money has already gone.

The frame of the regime fits into a few lines.

How it works in the United States

The American system is a benchmark of severity and of generosity at once. The default is 30% of the gross amount of any FDAP income (fixed, determinable, annual, periodical: dividends, interest, royalties, rent) paid to a foreign person from a US source. Expenses and losses play no part in the computation — the tax is taken on a gross basis. The withholding agent carries the liability: broker, bank, issuer alike. Under-withhold and it pays the difference out of its own pocket.

The 30% can be brought down only with documents. The cascade of W-8 forms is passport control for American payments: W-8BEN for individuals, W-8BEN-E for companies, W-8IMY for intermediaries and transparent structures, W-8ECI for income effectively connected with a US business. A W-8BEN is valid until 31 December of the third year following the year of signature — after which the broker quietly puts the client back on 30%. For trusts and multi-layered structures the cascade becomes a discipline of its own: everything turns on whom the forms show as the owner of the income; the detail is in the taxation of trusts.

The generosity is hidden in the portfolio interest exemption: interest on properly documented debt — registered form, the lender holding less than 10% of the borrower, bank lending excluded — is exempt from withholding altogether. Zero per cent with no treaty at all: this is how the United States has been feeding world demand for its debt market since 1984. A well-built loan structure saves 30% on every coupon, which is why an entire legal practice stands behind the dull words "registered obligation".

After that come the patches. Section 871(m) extended withholding to dividend equivalents: a swap or other derivative on an American share generates a "dividend equivalent" taxed like the dividend itself. The era of unencumbered swaps on individual US shares is over — with a reservation for broad indices, for which the rule itself left a door open (see the qualified index below). And section 1446(f) stretched withholding as far as capital transactions: when a foreigner sells an interest in a publicly traded partnership, the broker takes 10% of the gross proceeds. Sell a PTP for $100,000 and $10,000 goes at once, whatever the financial result of the trade.

Europe and the guardians of procedure

The classic of the genre is Switzerland. Verrechnungssteuer of 35% is withheld from every dividend paid by a Swiss issuer: hold Nestlé and a third of the dividend goes to Bern. The treaty rate for most non-residents is 15%, but the Swiss take the whole amount first and invite you to reclaim the difference — a form, a certificate of residence, certification by your own tax authority, dispatch to the Swiss Federal Tax Administration, and a wait. Three years are allowed for the claim; miss the deadline and you have made the Confederation a present of 20 percentage points.

The whole of continental Europe lives much the same way, and only the numbers and the forms change. Every country runs its own procedures in its own language, refunds drag on for months and years, and a noticeable share of investors simply give up: on the European Commission's estimates, unreclaimed WHT and the cost of the procedures run to billions of euros a year.

The cure has been prescribed, though with a delay. On 10 December 2024 the Council of the EU adopted the FASTER directive (Faster and Safer Relief of Excess Withholding Taxes). Two pillars: a single digital certificate of residence, the eTRC, to be issued within 14 days; and an obligation on member states to offer investors either relief at source — the reduced rate applied at the moment of payment — or a quick refund within a hard deadline of around 60 days. Add registers of certified financial intermediaries and standardised reporting along the whole payment chain, so that the fast procedures stay closed to fraudulent claims. National rules start to apply from 1 January 2030; until then the old paper world holds.

Royalties: the canon that never formed

The 0/5/15 dividend ladder does not carry over to royalties. The OECD model hands them to the state of residence in full, and you can see it in the live text of a treaty: US–Ireland Convention, Article 12(1) — "Royalties arising in a Contracting State and beneficially owned by a resident of the other Contracting State may be taxed only in that other State". The UN model leaves a blank in the same place — "the tax so charged shall not exceed ___ per cent [the percentage is to be established through bilateral negotiations]" — and keeps art. 12A on fees for technical services alongside it, in the same form. The rate is decided by whose treaty network you happen to be in.

The official American summary is IRS Table 1 in its May 2023 revision; here are the rates at source on royalties in the key jurisdictions.

The table is now in its third year and does not reflect the suspension of the treaty with Russia from 16 August 2024, so check the specific rate against the text of the treaty itself.

Within the EU, group royalties are exempted by Directive 2003/49/EC: Art. 1(1) — "exempt from any taxes imposed on those payments in that State, whether by deduction at source or by assessment" — with a participation threshold under Art. 3(b) of 25% of capital or voting rights. The definition in Art. 2(b) is wider than the model's: the leasing of industrial, commercial and scientific equipment counts as a royalty under the directive, whereas it was struck out of the OECD model in 1992 — so one and the same payment falls sometimes under art. 12 and sometimes under art. 7.

The most expensive major source is India: the Finance Act 2023 doubled the domestic rate on royalties and fees for technical services for non-residents — the last row of the table above. The domestic rate has climbed above the treaty rates, and the treaty now has to be earned with paperwork: a TRC, Form 10F, a PAN and an Indian return. From 1 April 2026 the Income-tax Act 2025 applies, and withholding on payments to non-residents has moved to section 393(2), with the formula "20% or DTAA".

Recharacterisation pays better than haggling over the rate. On 2 March 2021 the Supreme Court of India, in Engineering Analysis Centre of Excellence v. CIT, stripped software payments of royalty status: "What is licensed is sale of a physical object which contains an embedded computer programme and is, therefore, sale of goods" — the withholding obligation under s.195 falls away entirely. The United States closed the neighbouring question by regulation: Treas. Reg. §1.861-19(c)(1) — "A cloud transaction is classified as the provision of services" — for tax years beginning on or after 14 January 2025. Services do not fall within art. 12.

Then comes the arithmetical conflict with the IP box: withholding is taken on the gross royalty, while the preferential regime reduces the tax on net profit.

Cyprus's 3% on profit against India's 21.84% on the gross produces a foreign tax several times larger than the entire domestic liability, and the excess credit burns. The mechanics of the regimes are worked through in IP box. Americans have a further layer on top: the final FTC regulations in T.D. 9959 (January 2022) require the source country to source a royalty by the place where the intellectual property is used, and sourcing by the payer's residence disqualifies the tax altogether. The concession is the single-country license exception in the proposed rules REG-132569-17 (87 Fed. Reg. 71,271, November 2022): a written licence limited to the territory of the country imposing the tax, with a transitional rule covering agreements executed before 17 May 2023. As at August 2026 the finalisation of the exception is unconfirmed, so practice is leaning on a proposal.

Live performance and platforms: withholding with no threshold

Two perimeters of withholding sit outside passive income altogether, and both bite where nobody expects them.

Entertainers and sportspersons: article 17

The first perimeter is Article 17 of the OECD Model Convention, "Entertainers and Sportspersons": income earned by an artist or a sportsperson from personal activities is taxable in the state where the performance takes place, and the rule is introduced by the word "notwithstanding" as against the articles on business profits and on income from employment. The practical meaning of that override is that no permanent establishment is required and no 183-day threshold applies — a single concert or a single tournament match already creates a tax base.

The live text of a treaty reads word for word: UK–Germany DTC 2010, art. 16(1) — "income derived by a resident of a Contracting State as an entertainer … from his personal activities as such exercised in the other Contracting State, may be taxed in that other State", overriding arts. 7 and 14 in that treaty's numbering. Paragraph 2 closes the star-company route: income that "accrues not to the entertainer or sportsman himself but to another person" is still taxable where the activities are exercised.

Thresholds do exist, but only where they have been bargained for bilaterally: art. 16(1) of the UK–USA Convention 2001, as amended by the 2002 Protocol, leaves a performance alone where gross receipts for the year do not exceed "twenty thousand United States dollars ($20,000)".

The domestic machinery is gross-basis withholding: HMRC requires the payer to deduct at the UK basic rate of 20% from payments to foreign performers above the personal allowance, while the United States takes 30% of the gross income of a non-resident alien artist or athlete, and the only route to a net computation is a Central Withholding Agreement — Form 13930 and Rev. Proc. 89-47, with the application filed at least 45 days before the first event.

Platforms: what is on file in AdSense

The second perimeter is the platform, and it is harsher than the broker. Google acts as a withholding agent under chapter 3 of the Internal Revenue Code and withholds US tax on the slice of a channel's earnings generated by viewers in the United States; the rate depends on what has been submitted in AdSense.

The asymmetry is in the penalty for silence: 24% is the rate with which the IRS answers a missing or incorrect TIN, and it is taken not from the American slice but from worldwide earnings. The submission deadline is 10 December, and a W-8BEN, exactly as with a broker, runs until 31 December of the third year following signature. The arithmetic comes out counter-intuitive: a channel with 8% American audience and an expired form hands more to the US Treasury than a channel with an entirely American audience and a valid W-8BEN.

Credit at home: the other half of the calculation

Whatever is withheld at source stays a loss until the country of residence agrees to credit it. There is no general mechanism, and EU law does not create one: on 14 November 2006 the Grand Chamber of the CJEU held in Kerckhaert and Morres (C-513/04) that free movement of capital "does not preclude" a law taxing domestic and foreign dividends at the same rate "without providing for the possibility of setting off tax levied by deduction at source in that other Member State". The consequences "result from the exercise in parallel by two Member States of their fiscal sovereignty", and EU law lays down no common criteria for allocating competence. The credit remains a matter of national law and of treaty.

The United States gives its credit unilaterally: §901(b)(1) credits taxes paid "to any foreign country", with no treaty required. The limiters come further on, in four provisions of §904:

• §904(a) holds the credit to the proportion that foreign income bears to total taxable income;
• §904(d)(1) cuts income into baskets — §951A, foreign branch, passive category, general category; portfolio dividends and interest live in the passive basket, and spill-over between baskets is closed;
• §904(c) allows a one-year carry-back and a ten-year carry-forward;
• §904(j) releases small cases from Form 1116: all the foreign income is qualified passive income, the taxes are no more than $300 ($600 on a joint return), and the recipient is neither a trust nor an estate.

More detail in the article on FEIE and the foreign tax credit.

The trap is hidden in Treas. Reg. §1.901-2(e)(5): an overpayment above the treaty rate does not count as tax at all. The IRS Practice Unit puts it plainly — "Any foreign tax paid in excess of the amount of liability under foreign tax law (including applicable tax treaty) is a noncompulsory payment and therefore is not eligible for the FTC", and "Foreign taxes claimed by the taxpayer on a particular type of income can not exceed the tax rate provided by the tax treaty, regardless of the amount paid to or withheld by the foreign country". Hence the second, invisible layer of loss from an expired W-8BEN: the broker withheld 30% instead of the treaty's 15%, and the extra 15 percentage points will not be credited at home either — they have to be claimed from the source country, under its procedure and within its deadlines.

National ceilings on the credit

The United Kingdom is built along similar lines. TIOPA 2010 s.18 gives credit both "under double taxation arrangements" and "under unilateral relief arrangements", so a treaty is not required for the credit; s.33 symmetrically requires the taxpayer to have taken, in advance, "all reasonable steps … to minimise the amount of tax payable in that territory". Fail to claim the relief at source and you lose the British credit as well; the analysis is in foreign tax credit and treaties. Germany sets the ceiling in the provision itself: § 32d Abs. 5 Satz 1 EStG credits "höchstens 25 Prozent ausländische Steuer auf den einzelnen steuerpflichtigen Kapitalertrag" — 25%, and on each individual payment, with no common pot, so the Swiss 35% cannot be credited in full even in theory. § 34c Abs. 1 EStG gives a unilateral credit, and Abs. 6 switches it off "wenn die Einkünfte aus einem ausländischen Staat stammen, mit dem ein Abkommen zur Vermeidung der Doppelbesteuerung besteht".

Russia is the strictest of all towards individuals: under cl. 1 of art. 232 of the Tax Code, amounts paid abroad "are not credited against tax payable in the Russian Federation unless the relevant international treaty provides otherwise". Here the treaty creates the very right to a credit. It is claimed by return within three years after the end of the tax period in which the income was received (cl. 2).

Fund domicile: where exactly the percentages are lost

One and the same S&P 500 is taxed at different points through an American and through an Irish ETF. State Street, in a review of 2 June 2026, breaks this into two levels.

The Irish fund itself lives under gross roll-up: between those two points there is no tax.

The fifteen per cent inside the fund comes from the treaty: US–Ireland Convention, Article 10(2)(b) — "15 percent of the gross amount of the dividends in all other cases" — while Article 4(1)(d) expressly recognises as a resident "in the case of Ireland, a Collective Investment Undertaking". The Irish wrapper obtains the treaty rate in its own right, with no involvement from the investor.

Hence a conclusion that breaks the familiar "15% versus 30%": that comparison holds for an investor with no treaty with the United States. For a resident of a treaty country with a working credit the total burden is identical — 15% in both cases — and what differs is the point of withholding. In the American fund those 15% are taken from the investor himself and go onto his return as a creditable foreign tax; in the Irish one they have settled a level above, where the fund is the recorded recipient of the dividend. Germany has acknowledged the problem head-on: instead of a credit, the InvStG gives a flat-rate Teilfreistellung — § 20 Abs. 1 exempts 30% of the income of an Aktienfonds in the hands of a private investor. In most jurisdictions there is no express provision saying that fund-level withholding is unavailable to the unitholder, so check your own national law before drawing conclusions.

Ireland wins outright in two cases. The first is where there is no treaty with the United States: 15% against 30%. The second is US estate tax — under IRC §2104(a) shares are US-situs "only if issued by a domestic corporation", and units in an Irish UCITS do not meet the definition, whereas a non-resident holding American securities has a credit under §2102(b)(1) of only $13,000; see US estate tax. The counter-argument for the bond side of a portfolio: §871(k) takes interest-related dividends and short-term capital gain dividends of American RICs outside withholding, so a substantial part of a US fund's distribution reaches a non-resident free of tax.

Synthetics are alive too. Treas. Reg. §1.871-15(l) takes transactions on a qualified index outside the dividend equivalent rules: such an index "is treated as a single security that is not an underlying security". The S&P 500 itself clears every numerical threshold in (l)(3), on S&P Dow Jones Indices data as at 2 January 2026.

The remaining conditions in (l)(3) are not numerical: long positions only, rebalancing on publicly stated criteria, and futures or options traded on a qualified exchange. The provider does not formally confirm the index's status, but a swap-based UCITS on a broad index can still pay neither 15% nor 30%.

And then the arithmetic all of this is done for. At an S&P 500 yield of 1.15%, a fifteen per cent withholding costs around 17 basis points a year and a thirty per cent one around 35. The difference is comparable to the entire TER of a large index fund.

Anti-avoidance: the beneficial owner

The reduced rate belongs to the owner of the income — an entire industry cracked on that proposition. On 26 February 2019 the CJEU delivered its judgments in the "Danish cases" (N Luxembourg 1 on interest, T Danmark on dividends): where income merely passes through a holding company in transit to its real owner, that holding company cannot be recognised as the beneficial owner, and the benefit of the directive or the treaty is lost. More than that, a state is obliged to counter the abuse even without a specific provision in its national law, because the prohibition of abuse of rights is a general principle of EU law.

The court listed the markers of transit outright: the money moves on almost immediately and almost in full, and the company has no office, no staff and no real power to dispose of the income. In short, there is no substance; what that is and how it is built is worked through in economic substance.

In parallel, the OECD covered the treaty network with the MLI: the multilateral instrument wrote a principal purpose test into practically every treaty in force — the benefit is withdrawn if obtaining it was one of the principal purposes of the structure. How the MLI rebuilt treaty shopping, and how the PPT works alongside GAAR, are covered in a separate article.

For "Cypriot interlayers" — holding companies inserted into the chain for the sake of a 5% dividend rate instead of 15% — all of this adds up to a sentence: the source country's tax authority looks straight through the interlayer, applies the rate appropriate to the ultimate recipient and assesses additional tax for past periods. What a Cypriot company needs today in order to survive such an audit is in Company: Cyprus.

WHT as a weapon

Withholding at source is the perfect instrument of pressure: it works instantly, it is administered by someone else's hands, and it hits the investor directly.

Russia, August 2023: a presidential decree suspended the key articles of the double tax treaties with 38 "unfriendly" states. The reduced rates vanished in both directions. Dividends now leave Russia at the domestic 15% (Article 284(3)(3) of the Tax Code) and interest and royalties at 25% from 1 January 2025 (Article 284(2)(1) of the Tax Code, as amended by item 50(zh) of Article 2 of Federal Law No. 176-FZ of 12 July 2024; payments made in 2023–2024 were taxed at 20%); travelling the other way are the full rates of American and European sources with no treaty discount. The double taxation that treaties had muffled for half a century came back at full height, on territory previously regarded as neutral.

The United States, 2025: the House version of the One Big Beautiful Bill Act carried a section 899, promptly christened the "revenge tax" by the press. The mechanics: plus 5 percentage points a year, up to +20, on withholding rates for persons from countries with "unfair taxes" — read, with digital services taxes and the UTPR from Pillar Two. Global funds had time to recalculate the returns on their American portfolios, and lawyers to bill for the memoranda. At the end of June 2025 §899 was struck out of the bill: the G7 agreed a side-by-side construction taking American groups outside the IIR and the UTPR, and in exchange the United States put down the club. The precedent is on the record — the rate at source has officially become something great powers bargain over.

The most awkward question raised by the suspension is what became of the credit. Decree No. 585 stopped the listed articles rather than the treaties as a whole.

The articles on the elimination of double taxation stayed out of most of those lists, and Pepeliaev Group and EPAM read that as preserving the credit as before.

For the British pair that analysis has been moot since spring 2025: the UK side switched the 1994 Convention off in full — the Double Taxation Relief (Russian Federation) (Revocation) Order 2025 (SI 2025/344, made 12 March 2025) revoked the 1994 implementing order (SI 1994/3213), and the Convention has no effect in UK law for the financial year beginning 1 April 2025 for corporation tax or for the 2025-26 tax year, beginning 6 April 2025, for income tax and capital gains tax. There is no treaty credit left in that pair — only the unilateral credit under TIOPA 2010 s.18.

Both firms qualify the point immediately: in the treaties with Cyprus, Switzerland and Germany the credit is tied to tax levied "in accordance with the Agreement", and those articles are suspended. As at August 2026 there is no official guidance from the Ministry of Finance or the Federal Tax Service on crediting the increased rates specifically, so the question stays open.

With the United States it is harsher: the suspension has run on the American side from 16 August 2024, from which date "reduced rates of withholding tax no longer apply" — the statutory 30% governs. EY treats art. 22 (Relief from Double Taxation) as having fallen away with them, since it was precisely para. 4 of art. 1 that carved it out of the saving clause: the treaty credit is dead and the statutory §901 remains. The detail is in Russia's suspension of its tax treaties.

Germany, 2027: on 30 June 2026 Berlin notified Moscow that the treaty of 29 May 1996 and its Protocol "mit Wirkung vom 1. Januar 2027 suspendiert wird". From 2027 there will be no treaty rates at all in German–Russian flows. Whether that brings back the unilateral credit under § 34c Abs. 1 EStG is an open question: a suspended treaty formally continues to "bestehen", and Abs. 6 is capable of blocking the credit even so. The BMF announcement of 9 July 2026 did not clarify the point.

Risks

Popular, and it ends badly

Cum-ex and cum-cum: a refund of tax nobody paid. Short sales of shares around the dividend record date created, for several participants at once, the appearance of owning one and the same security — and each of them claimed from the treasury a refund of the same withheld tax. Cum-cum worked more quietly: for the day of the record date the securities "moved" to a local bank entitled to a refund, and the benefit was shared out among the participants. The denouement: the aggregate damage to European budgets is put at more than €150bn, the courts are handing out real prison terms to bankers and tax lawyers — Hanno Berger received eight years in Germany, Sanjay Shah twelve in Denmark — and the prosecutors in Cologne and Copenhagen are still grinding through hundreds of episodes.

"The Cypriot holding company with a single director." A company with a nominee director, no office and no employees, inserted between the operating business and the owner for the sake of a 5% dividend rate. The denouement: after the CJEU's Danish cases and the PPT everywhere, such interlayers are unpicked as a matter of routine — the source country refuses the treaty rate retrospectively, assesses the difference with interest, and years of accumulated savings turn into a loss with interest on top. Substance requirements have gone from the exotic to the bare subsistence minimum of any holding company.
