Switzerland Investment Income Tax Guide 2026

Dividends from Swiss Companies — Partial Taxation

• Partial taxation system (Teilbesteuerungsverfahren): Dividends received by individuals from Swiss companies (AG, GmbH) are partially exempt from income tax. The exemption percentage depends on the canton of residence. At the federal level, 50% of the dividend is exempt (60% for dividends from shares held as business assets). At the cantonal level, exemptions range from 50–70%, depending on the canton. Zurich exempts 50%, Zug 50%, Geneva 50%, Vaud 50%, Basel-Stadt 50%. Some cantons (e.g., Schwyz, Nidwalden) exempt 60–70%.
• Rationale: The partial taxation system aims to avoid economic double taxation. The company paying the dividend has already paid corporate income tax on its profits. Without partial taxation, the shareholder would be taxed again on the same economic income — effectively triple taxation (corporate tax + dividend income tax + wealth tax on the share value). The partial exemption is an approximation of full imputation relief.
• Calculation example: You receive CHF 100,000 in dividends from a Swiss company. You are resident in Zurich (50% exemption at cantonal level, 50% at federal). Taxable amount: CHF 50,000 (federal) and CHF 50,000 (cantonal). The CHF 50,000 is added to your other income and taxed at progressive rates. Your marginal tax rate is 35%, so the additional tax due is approximately CHF 17,500 (plus withholding tax refund — see below).
• Qualifying shares: The partial taxation applies to dividends from shares held as private assets (Privatvermögen) and business assets (Geschäftsvermögen), but with different exemption percentages. For business assets, the federal exemption is 60% (instead of 50%), and the cantonal exemption may also be higher. The distinction between private and business assets is important for self-employed individuals and entrepreneurs.

Dividends from Foreign Companies

• Full taxation (no partial exemption): Dividends from foreign companies are fully taxable — the partial taxation system applies only to dividends from Swiss companies. There is no exemption for foreign dividends at either federal or cantonal level. This means foreign dividends are taxed at the full progressive rate (up to 40%+ in high-tax cantons).
• Foreign tax credit (FTC): If the foreign country has withheld withholding tax on the dividend (e.g., 15% in the US, 26.375% in Germany, 30% in France), the Swiss resident can claim a foreign tax credit against their Swiss income tax liability. The credit is limited to the Swiss tax attributable to the foreign dividend (per-country limitation). Unused credits cannot be carried forward or refunded.
• Tax treaty rates: Swiss residents benefit from reduced withholding tax rates under Switzerland's extensive network of double tax treaties. The standard treaty rate is typically 15% for portfolio dividends and 0% for qualifying participation dividends (10%+ holding). To claim the reduced rate, the Swiss resident must submit the relevant form to the foreign paying agent before the dividend payment (W-8BEN for US, the relevant A1/A3 form for EU countries).
• Reporting: Foreign dividends must be reported in the tax return at the gross amount (before foreign withholding tax). The foreign tax credit is claimed separately in the tax return. The net cash dividend (after foreign tax) is the actual amount received; the tax due is calculated on the gross amount, and the credit offsets the Swiss tax. The taxpayer must provide proof of foreign tax withheld (tax voucher, broker statement).

Interest Income — Fully Taxable

• Full taxation: Interest income from all sources (bank accounts, bonds, notes, loans, money market instruments) is fully taxable at ordinary progressive rates (federal and cantonal). There is no partial exemption or allowance for interest income. The interest accrued up to 31 December of the tax year is taxable, even if not yet credited to the account.
• De minimis exemption (occasional interest): Very small amounts of interest on savings accounts (up to approximately CHF 100–200 per year) may be exempt in some cantons as occasional income (Nebeneinkünfte). The federal tax law does not provide a specific exemption for small interest amounts, but in practice, amounts below CHF 50 are often not pursued by tax authorities.
• Capital gains vs interest: The distinction between interest (fully taxable) and capital gains (tax-free) is important for bonds. The coupon interest on a bond is fully taxable. However, if you buy a bond at a discount and hold it to maturity, the discount is generally treated as interest (not capital gain) — it is taxable. If you sell a bond at a premium before maturity, the gain may be tax-free as a capital gain, but the accrued interest component is taxed as interest.
• Negative interest: During the period of negative interest rates (2014–2022), the interest paid by banks to depositors was effectively zero. Negative interest charged by banks to depositors was not deductible for private individuals. Since interest rates have normalised, positive interest on savings and bond investments is once again generating taxable income for many investors.

Capital Gains — Tax-Free for Private Individuals

• Reminder: Capital gains on the sale of movable property (shares, bonds, mutual funds, ETFs, crypto, forex, precious metals) are tax-free for private individuals. This is one of the most important features of the Swiss tax system for investors. See our Capital Gains Guide → for full details, including the professional securities dealer exception.
• Fund distributions: Mutual funds and ETFs typically distribute dividends and interest (taxable as income) and capital gains (tax-free for Swiss funds under certain conditions). Swiss funds are required to publish tax-relevant data (steuerrelevante Daten) each year showing the breakdown of distributions between taxable income, tax-free capital gains, and other components. Investors must use these data for their tax returns.

Withholding Tax (Verrechnungssteuer) — 35%

• How it works: Swiss companies and banks are required to withhold 35% withholding tax (Verrechnungssteuer / impôt anticipé) on dividends paid to shareholders and on interest paid on bonds and bank accounts. The 35% is deducted from the gross payment — the shareholder receives only 65% of the gross dividend or interest.
• Refund for Swiss residents: For Swiss residents, the 35% withholding tax is fully refundable. The refund is claimed through the tax return process — the withheld tax is reported in the tax return, and the cantonal tax authority offsets it against the total tax due. If the withholding tax exceeds the total tax due, the excess is refunded. The refund is effectively automatic for properly filed tax returns.
• DA-1 form (separate refund): Taxpayers who are not required to file a tax return (e.g., employees with withholding tax only) can file a DA-1 form (Abfaltung 1) with the Federal Tax Administration (ESTV) to claim a refund of the 35% withholding tax on dividends and interest. The form requires proof of the withholding tax deducted (tax voucher, bank statement). The refund is typically processed within 2–4 months.
• Non-residents: Non-residents cannot reclaim Swiss withholding tax in most cases — the 35% is a final tax. However, under double tax treaties, non-residents may qualify for a reduced withholding tax rate (typically 15% for portfolio dividends, 0% for qualifying holdings). To claim the reduced rate, the non-resident must submit a withholding tax exemption form to the Swiss paying agent before the payment. The reduced rate relieves the non-resident from filing a refund claim.
• Refund deadline: Swiss residents have 3 years from the end of the calendar year in which the withholding tax was deducted to claim a refund. After 3 years, the refund right lapses (Verwirkung). Taxpayers who file late returns may lose the refund for older withholding tax amounts. It is important to file the tax return on time to avoid forfeiting the refund.

Reporting Requirements

• Swiss accounts: Investment income from Swiss bank accounts and securities accounts is pre-filled in the tax return in many cantons (automatic data transmission from banks to tax authorities). The taxpayer should verify the pre-filled data and add any missing items (e.g., foreign dividends, crypto income).
• Foreign accounts (declaration): Swiss residents must declare their foreign bank accounts, securities accounts, and other foreign investment assets in the tax return. There is no wealth reporting threshold — all foreign assets must be declared regardless of value. The declaration includes: account number, bank name, country, and the total value as at 31 December. Investment income from foreign accounts (dividends, interest) must be reported separately.
• Automatic exchange of information (AEOI): Switzerland participates in the OECD's AEOI framework, automatically exchanging financial account information with over 100 countries. Foreign tax authorities receive data on Swiss residents' foreign accounts (balance, dividends, interest, sale proceeds). Swiss tax authorities receive reciprocal data on Swiss residents' accounts abroad. Non-disclosure of foreign accounts and investment income carries significant penalties (10–30% of omitted tax, plus interest, plus potential criminal prosecution for tax evasion — Steuerbetrug).

FAQs

Why is only part of the dividend taxable?

The partial taxation system (Teilbesteuerungsverfahren) avoids economic double taxation. The company has already paid corporate tax on its profits before distributing dividends. Without partial taxation, the dividend would be taxed twice — once at corporate level and again at shareholder level. The partial exemption (50–70% at cantonal level, 50% at federal) ensures that the combined corporate + personal tax burden on distributed profits is reasonable.

How do I reclaim the 35% withholding tax?

If you file a Swiss tax return, the 35% withholding tax is refunded through the tax return — you report the gross dividend/interest and the withheld tax, and the cantonal tax authority offsets the withheld amount against your total tax due. If you do not file a return (e.g., because you are on withholding tax only), you can file a DA-1 form with the ESTV to claim a refund. The refund right lapses after 3 years.

Are dividends from US companies taxed in Switzerland?

Yes. Dividends from US companies are fully taxable in Switzerland at ordinary progressive rates (no partial exemption, since the company is not Swiss). The US imposes a 15% withholding tax (under the treaty) on dividends paid to Swiss residents. The Swiss tax authority provides a foreign tax credit for the US withholding tax. The net effect: you pay the Swiss marginal rate minus the US 15% credit. For a Swiss taxpayer in the 30% bracket, the additional Swiss tax is approximately 15% (30% minus 15% credit).

Is interest on a Swiss bank account taxable?

Yes. Interest on savings accounts, fixed-term deposits, and current accounts is fully taxable as income. Swiss banks automatically report interest paid to account holders to the tax authority. The 35% withholding tax (Verrechnungssteuer) is deducted from interest payments on bonds and some bank accounts — it is refundable through the tax return. Small amounts of savings interest (under approximately CHF 50–200) may not be pursued by tax authorities but should still be declared.

Do I pay tax on capital gains from my fund investments?

No, if you hold the funds as a private individual. Capital gains from selling fund units are tax-free (assuming you are not a professional securities dealer). However, distributions from the fund are taxed as follows: dividends and interest paid by the fund are taxable as investment income; capital gains realised by the fund and distributed to unitholders are tax-free for Swiss funds. Swiss funds publish annual tax data (steuerrelevante Daten) showing the breakdown.
