Swiss Withholding Tax (Verrechnungssteuer): Rate, Refund & DTA Claims

Swiss withholding tax — officially the Verrechnungssteuer, governed by the Federal Act on Withholding Tax (VStG, SR 642.21) — is a 35% federal tax deducted at source on dividends, bond interest, and certain other investment income paid by Swiss entities. It applies uniformly across all 26 cantons. For Swiss residents, it functions as a compliance mechanism: the full amount is refunded once the income is declared in the annual tax return. For non-residents, the refund is partial and depends on the applicable double taxation agreement (DTA) between Switzerland and the investor's country of residence.

This guide covers the legal basis, the scope of taxable payments, the refund procedures for residents and non-residents, the DTA framework, and the implications for Swiss companies paying dividends. References throughout are to the VStG and the Federal Tax Administration (ESTV, estv.admin.ch).

What Is Swiss Withholding Tax?

The Verrechnungssteuer is a safeguard tax — its primary purpose is not to generate revenue from Swiss residents but to ensure that investment income is declared for cantonal and federal income tax purposes. A taxpayer who fails to declare dividend or interest income in their tax return cannot recover the 35% already withheld. This creates a powerful incentive for compliance.

The ESTV (Eidgenossische Steuerverwaltung / Swiss Federal Tax Administration) administers the tax. It is deducted by the paying entity — the Swiss company, Swiss bank, or Swiss bond issuer — which remits the 35% to the ESTV and pays the net 65% to the recipient. The recipient then claims back the withheld amount through the appropriate refund route.

What Payments Are Subject to Withholding Tax?

VStG Art. 4 sets out the taxable objects. The three main categories are:

Dividends and profit distributions

Dividends paid by Swiss-resident companies (AG, GmbH, cooperative) to their shareholders are subject to 35% withholding tax. This includes ordinary cash dividends, liquidation surpluses distributed above the paid-in capital, and certain deemed distributions (such as the write-off of shareholder loans that represent a hidden dividend). Capital repayments from statutory reserves that were originally paid in by shareholders (capital contribution reserves, Kapitaleinlageprinzip) are exempt from withholding tax — this is an important planning consideration for Swiss holding structures.

Interest on bonds and bank deposits

Interest on bonds and similar debt instruments issued by Swiss-resident debtors is subject to 35% withholding tax (VStG Art. 4(1)(b)). Interest on deposits held at Swiss banks (savings accounts, fixed-term deposits) is also subject to the 35% rate. Intercompany loans do not generally fall under this provision provided they do not constitute a bond-like instrument: under the "10/20 rule" (VStG Art. 4(2)), a debt instrument triggers withholding tax treatment as a bond if more than 10 investors hold it (or more than 20 investors for bearer instruments), regardless of documentation. Companies with shareholder loans should structure these carefully to remain outside this rule.

Lottery and gambling winnings

Winnings from Swiss lotteries and games of skill above CHF 1,000 are subject to the 35% withholding tax under the Gambling Act provisions. Life annuities and pensions are taxed at the lower rate of 15%. Certain insurance payouts are subject to 8%.

The 35% Rate — How It Works in Practice

When a Swiss AG (Aktiengesellschaft) resolves to distribute a dividend of CHF 100 per share, the shareholder receives CHF 65. The remaining CHF 35 is remitted by the company directly to the ESTV, typically within 30 days of the dividend resolution (VStV Art. 21(3)). The company files a withholding tax return (Form 103 for AG, Form 110 for GmbH) reporting the total distributions and the withheld amounts.

The paying entity — not the shareholder — bears the compliance obligation for withholding and remitting the tax. Failure to withhold or late remittance exposes the paying company to interest charges and potential penalties. In practice, Swiss corporate administrators (Verwaltungsrat members, company secretaries) treat withholding tax compliance as a standard board resolution checklist item alongside the dividend resolution itself.

Refund for Swiss Residents — Full Recovery via Tax Return

For individuals domiciled in Switzerland, the 35% withholding tax is fully refunded — but only if the underlying income and assets are properly declared in the cantonal tax return. The tax return must show: (a) the gross dividend or interest income, and (b) the corresponding asset (the shares or the bank account) in the securities and asset schedule. The cantonal tax authority then credits the withheld 35% against the taxpayer's total cantonal and federal income tax liability.

If the credit exceeds the total income tax due — for example, for low-income taxpayers who own shares — the excess is refunded as a cash payment. The processing time varies by canton, but most cantonal authorities process withholding tax credits within the standard assessment cycle of six to twelve months after the tax return deadline.

For Swiss-resident legal entities (AG, GmbH, foundations, cooperatives), the refund route is different: the entity applies directly to the ESTV for a refund by submitting Form 25 within three years of the relevant withholding event. The condition for refund is that the income has been correctly recognised in the commercial accounts. This is the standard procedure for holding companies recovering WHT on subsidiary dividends — it is a timing mechanism only and creates no net tax cost for the corporate group.

Partial Refund for Non-Residents — Double Taxation Agreements

For investors not resident in Switzerland, the 35% withholding tax is in principle a final tax under domestic Swiss law. However, Switzerland has concluded double taxation agreements (DTAs) with over 100 countries. Where a DTA is in force, the non-resident investor is entitled to a refund of the difference between the 35% withheld and the reduced treaty rate — but must file an active claim to recover it.

Rates in the table above are indicative. Actual treaty rates must be verified against the current treaty text and any applicable protocols. The SIF (State Secretariat for International Finance) maintains the authoritative list of Swiss DTAs at sif.admin.ch. [VERIFY specific treaty rates before relying on them for planning.]

Treaty benefits are not applied automatically at source. The paying Swiss company withholds the full 35% in all cases. Non-resident shareholders who wish to benefit from a DTA must file a refund claim after the withholding event. Some treaties allow for reduced-rate withholding at source (procedure de remboursement) where the non-resident shareholder notifies the paying company in advance — but this procedure is available only for certain categories of shareholders and must be pre-approved by the ESTV.

How to Claim a Refund — Procedure, Forms, and Timelines

Swiss residents (individuals)

No separate form is required. The taxpayer declares the gross income and the underlying asset in the cantonal income tax return. The withholding tax credit is applied automatically by the cantonal tax authority. If the withholding tax certificate (Bescheinigung / certificat) from the Swiss bank or company is not included in the return, the cantonal authority will request it during assessment.

Swiss-resident legal entities

The legal entity submits Form 25 (Antrag auf Ruckerstattung der Verrechnungssteuer) directly to the ESTV in Bern. The application must be filed within three years of the end of the calendar year in which the withholding tax became due. Supporting documents include: the dividend or interest voucher, the ESTV payment receipt, and the extract from the commercial accounts showing the income was recognised.

Non-residents — Form 60 and treaty forms

Non-resident claimants use Form 60 (Anspruch auf Ruckerstattung der schweizerischen Verrechnungssteuer — Domizil im Ausland) for general DTA claims. Certain country pairs have dedicated forms: US residents use Form R-US 164 under the Switzerland–USA DTA; German residents use Form R-D under the Switzerland–Germany DTA. All forms are available from estv.admin.ch. The claim must be accompanied by:

• ›A certificate of tax residency (Ansassigkeitsbescheinigung) issued by the tax authority of the claimant's country of residence, confirming that the claimant is the beneficial owner of the income and is resident in that country for treaty purposes
• ›The original Swiss withholding tax certificate or a certified copy showing the gross income, the amount withheld, and the date of payment
• ›Proof of beneficial ownership — the DTA refund is only available to the beneficial owner of the income, not to a nominee or intermediary
• ›The completed treaty-specific claim form, signed and dated

The ESTV processes non-resident refund claims and issues the refund to the claimant's foreign bank account. Processing times vary; straightforward claims are typically processed within four to six months. Claims involving complex ownership structures or intermediaries take longer.

Withholding Tax and Swiss Companies — Dividend Distributions

For Swiss-incorporated companies distributing dividends, withholding tax compliance is a board-level obligation. The sequence at each dividend distribution is:

• ›The annual general meeting (Generalversammlung) approves the dividend based on the audited financial statements
• ›The board of directors (Verwaltungsrat) executes the payment: 65% net to shareholders, 35% remitted to the ESTV within 30 days of the due date (VStV Art. 21)
• ›Form 103 (for AG) or Form 110 (for GmbH) is filed with the ESTV reporting the total gross dividend and the withheld amount
• ›Each shareholder receives a withholding tax certificate (Bescheinigung) for use in their refund claim

The capital contribution principle (Kapitaleinlageprinzip, DBG Art. 20(3)) deserves specific attention: amounts distributed from capital contribution reserves — paid-in capital that was not deducted as an expense at the level of the paying company — can be returned to shareholders free of withholding tax. This is an important structural consideration for companies planning distributions from equity raised in prior financing rounds or share premium.

For Swiss holding companies within a domestic group structure, the withholding tax on subsidiary dividends flows up to the holding company, which recovers the 35% via Form 25 to the ESTV. This is a timing cash-flow item only. Swiss groups with active treasury management typically time their Form 25 filings to coincide with the cash flow planning cycle.

Interaction with Swiss Corporate Tax

Withholding tax is entirely separate from Swiss corporate income tax (Gewinnsteuer) and the Swiss corporate tax framework. A company pays corporate income tax on its net profits; it then pays out dividends from after-tax profits, and those dividend distributions trigger the 35% withholding tax at the shareholder level.

For companies based in Zug — where the combined corporate income tax rate is 11.85% (federal plus cantonal plus municipal) — the overall tax burden on a distributed profit is: 11.85% corporate income tax, then 35% withholding tax on the net dividend amount, recoverable by Swiss resident shareholders. For non-resident shareholders in a DTA country with a 15% treaty rate, the effective combined tax burden (corporate tax plus irrecoverable WHT) is approximately: 11.85% + (35% - 15%) × 88.15% = approximately 29.5% on pre-corporate-tax profit [VERIFY for specific fact patterns].

Individual investors in Switzerland benefit from the partial dividend taxation rule (Teilbesteuerung, DBG Art. 20(1bis)): dividends from qualifying shareholdings (at least 10% of share capital) are only 70% taxable at the federal level and at varying proportions at the cantonal level. Combined with full WHT recovery, this makes Swiss resident majority shareholders substantially better placed than non-resident minority shareholders. For a detailed treatment of Swiss tax obligations for companies and individuals, see the dedicated overview.

Foreign nationals considering relocation to Switzerland — including those with significant investment portfolios generating dividend and interest income — may benefit from lump-sum taxation (Pauschalbesteuerung), which changes the basis on which Swiss income tax is assessed and interacts differently with the withholding tax refund mechanism. Eligibility and conditions should be assessed with a Swiss tax adviser before relying on this route.
