Understanding Swiss Withholding Tax: What Is It, Who Pays It, and How do You Reclaim It?

Swiss withholding tax applies primarily to income from movable capital assets, but it also covers certain types of insurance and lottery winnings.

The most commonly taxed income types are:

• Dividends distributed by Swiss companies,
• Interest paid on Swiss bonds and bank accounts,
• Lottery and gambling winnings from Swiss sources,
• Annuities and pensions,
• Capital benefits from certain insurance policies.

The default withholding rate is a flat 35%, which applies to dividends, interest, and lottery winnings. Annuities and pensions are subject to a reduced rate of 15%, while capital payments from insurance policies may be taxed at 8%.

Importantly, it’s not who receives the income that determines whether withholding tax applies, but where the income originates. If the payer is based in Switzerland, the income generally falls within scope.

While the 35% flat rate might seem high at first glance, it’s only intended as a compliance tool rather than a permanent tax burden for those who report their income properly. In most cases, the tax is fully or partially refunded depending on the taxpayer’s residence and whether a double taxation agreement applies.

Withholding tax must be paid by any natural or legal person who receives income from Swiss sources that falls within the scope of the Federal Withholding Tax Act. It applies to both Swiss and foreign residents, though the eligibility and process for reclaiming the tax differ.

Swiss residents

Swiss individuals can reclaim the tax by declaring the income in their annual tax return. If the income (e.g. dividends, interest) is reported correctly, the withholding tax is credited against their total cantonal and federal tax liability. If the withheld amount exceeds the total tax due, the remaining balance is paid out in cash by the cantonal tax authorities.

Swiss legal entities (e.g., companies, associations, or foundations) submit their refund claims directly to the Federal Tax Administration (FTA). The claim must be filed using the official form and typically includes supporting documentation such as financial statements and dividend records. The refund is usually processed in the calendar year following the year in which the income was received.

Foreign residents

Foreign investors are also entitled to a (full or partial) refund under Switzerland’s double taxation agreements. The applicable treaty determines whether a refund is allowed and, if so, the maximum refundable rate (typically 10% to 15% for dividends and often 0% to 10% for interest).

Foreign applicants must submit the appropriate country-specific reclaim form to the FTA, proof of residence in the treaty country, and other supporting documentation such as proof of the income received and the withholding tax that was deducted.

Why do foreign residents only receive a partial refund?

It’s important to note that foreign investors do not declare their Swiss investment income in Switzerland, as they are not subject to Swiss income tax. Instead, they declare it in their home country. For this reason, the full 35% is not refunded.

Switzerland retains the portion it is entitled to under the applicable treaty, and the investor typically receives a tax credit in their home country for that amount. This ensures the income is taxed primarily where the investor resides while still allowing Switzerland to tax income sourced from within its borders.

Example:

A French resident receives CHF 1,000 in dividends from a Swiss company. Switzerland applies a 35% withholding tax, deducting CHF 350. Under the France–Switzerland tax treaty, Switzerland is entitled to retain 15%. The French investor can reclaim CHF 200 from the Swiss tax authority (to reduce the effective Swiss tax to 15%). In France, dividend income is taxed at a flat rate of 30% (including income tax and social charges). France allows the investor to deduct the CHF 150 Swiss tax already paid, so the investor pays only the remaining CHF 150 to French tax authorities.

This results in a total tax burden of CHF 300 (30%), split equally between Switzerland and France, without double taxation.

Under normal circumstances, the refund application can only be submitted after the end of the calendar year in which the taxable benefit became due (Art. 29 – VStG).

However, there are exceptions allowing for earlier refunds:

• Early refund: In special cases (e.g., relocation abroad, death) or in cases of hardship, an early refund request may be submitted (Art. 29 para. 3 VStG).
• Interim refunds (installments): If an applicant (typically a legal entity) can credibly demonstrate that their annual refund entitlement will amount to at least CHF 4,000, they may apply for interim refunds from the Federal Tax Administration (FTA). A final, comprehensive refund application must be submitted within three months after the end of the year (Art. 65 – VStV).

What is the time limit for making claims?

The right to a refund expires three years after the end of the year in which the taxable income was due (Art. 32 VStG).

What is the processing time of refunds?

Refunds are typically processed within several months. No formal confirmation of receipt is sent, but applicants can check the status via the FTA’s ePortal.

While the Swiss withholding tax system is well-organized, there are several practical challenges that can lead to delays, penalties, or unnecessary tax costs if not handled correctly.

• Incorrect withholding: Failure to withhold properly can have serious consequences. If the payer neglects their withholding duty, the total amount paid to the recipient is treated as a net amount, and the 35% tax is recalculated on a grossed-up basis, leading to an effective tax rate of over 50%. See the FAQ section for further explanation of how this works in practice.
• Documentation: Incomplete, outdated, or incorrectly filled forms are one of the most common causes of delays or rejections in the refund process. Supporting documents must be complete, accurate, and consistent with the submitted claim.
• Administrative fines: Failure to comply with proper withholding tax obligations, such as notification procedures for intra-group dividends or timely reporting of taxable events, can lead to administrative penalties. These fines are typically imposed by the FTA and can apply even if the underlying tax is eventually refunded.
• Inheritance and co-ownership: Special procedures apply when income or assets are held jointly, such as in estates or co-ownership associations. For income received after the date of death, each heir typically files a refund application individually. In some cases, a representative may file on behalf of the community of heirs, provided proper documentation and authorization are in place.
