How Money Market Accounts Are Taxed in Switzerland (2026)
Learn how money market accounts are taxed in Switzerland in 2026 — withholding tax, income reporting, wealth tax, and how to reclaim what you're owed.
Fiscalité
Introduction
If you hold a money market account or invest in money market funds in Switzerland, you are probably earning interest income — and that income is taxable. The question most people ask is: how exactly does the Swiss tax system treat it, and what do you actually owe?
Switzerland has a clear but layered approach to taxation on money market accounts. It starts with a 35% withholding tax deducted at source, moves through your annual tax return, and ends — for most Swiss residents — with a full refund of that withholding, provided you declare everything correctly. But there are nuances: wealth tax, cantonal differences, and the treatment of money market funds versus bank accounts all play a role.
This guide breaks it all down — clearly, accurately, and with the latest 2026 figures — so you know exactly where you stand.
What Is a Money Market Account?
A money market account is a type of deposit or investment account that earns interest based on short-term, low-risk instruments — such as government treasury bills, short-term bonds, and interbank loans. In Switzerland, these accounts are offered by major banks and asset managers, and they come in two main forms:
1. Bank-based money market accounts
These function similarly to high-yield savings accounts. Your capital sits with the bank, earns interest, and is protected by the Swiss deposit guarantee up to CHF 100,000.
2. Money market funds
These are collective investment vehicles (UCITS or Swiss-domiciled funds) that pool capital and invest in short-term debt instruments. Examples include UBS CHF Money Market Fund and similar products from Pictet and other Swiss asset managers.
Both types generate investment income in the form of interest or distributions. And in Switzerland, that income is subject to tax — specifically, the Swiss anticipatory tax (Verrechnungssteuer) and, ultimately, income tax at the federal, cantonal, and municipal levels.
As of March 2026, the Swiss National Bank (SNB) policy rate stands at 0%, which means money market yields in CHF are modest — typically between 0.05% and 0.5% for bank accounts, and slightly higher for money market funds. Despite the low rates, the tax rules still apply in full.
The 35% Withholding Tax: How It Works
The most important thing to understand about the money market interest tax in Switzerland is the anticipatory tax (Verrechnungssteuer). This is a federal withholding tax levied at source on investment income — including interest from bank accounts and distributions from money market funds.
The rate is 35% — and it is deducted automatically by the bank or fund manager before you receive your interest payment. So if your money market account earns CHF 1,000 in interest, you will only see CHF 650 credited to your account. The remaining CHF 350 goes directly to the Swiss Federal Tax Administration (SFTA / ESTV).
Here is the key point: this 35% is not a final tax for Swiss residents. It is a safeguard mechanism designed to prevent tax evasion. If you correctly declare your interest income and the corresponding assets in your annual tax return, you are entitled to a full refund of the 35% withheld.
The refund is typically offset against your cantonal and municipal taxes. In practice, the withholding tax acts as a prepayment — you declare the income, the withholding is credited, and you pay the net difference based on your actual marginal tax rate.
What Happens If You Don't Declare?
If you fail to declare your money market interest income, you forfeit your right to the refund. The 35% becomes a permanent charge. On top of that, you may face penalties for undeclared income. The Swiss tax system is built on the principle that honest declaration is rewarded — and non-declaration is penalised.
Interest Income Reporting and Income Tax
Once you declare your money market interest, it is added to your total taxable income and taxed at your marginal rate. Switzerland taxes income at three levels: federal, cantonal, and municipal. The combined effective rate varies significantly depending on where you live.
For interest income reporting, you will typically find the relevant figures on your annual bank statement or fund distribution notice. Swiss banks are required to provide a tax certificate (Steuerausweis / attestation fiscale) that lists all interest earned and withholding tax deducted during the year. This document is your primary reference when completing your tax return.
Here is a simplified example of how the investment income tax calculation works for a Geneva resident:
- Gross interest earned: CHF 2,000
- Withholding tax deducted (35%): CHF 700
- Net received: CHF 1,300
- Declared on tax return: CHF 2,000 (gross)
- Marginal income tax rate (Geneva, example): ~30%
- Actual income tax owed: CHF 600
- Withholding tax refunded: CHF 700
- Net outcome: CHF 100 refund
This is why declaring your tax on savings interest correctly is not just a legal obligation — it is often financially beneficial. Many Swiss residents actually receive a net refund after filing.

Money Market Fund Taxation: What's Different?
When you invest in a money market fund rather than a direct bank account, the tax treatment follows the same general principles — but with a few important distinctions.
Swiss-Domiciled Money Market Funds
For Swiss-domiciled funds, the fund management company can apply for a refund of Swiss federal withholding tax on domestic income earned within the fund. The fund then distributes income net of tax, and investors receive a tax certificate showing the gross distribution and any withholding applied. You declare the gross amount in your tax return and claim the withholding back.
Foreign-Domiciled Money Market Funds
If you hold a foreign-domiciled money market fund (for example, a Luxembourg or Irish UCITS fund), the Swiss withholding tax does not apply at the fund level. However, any distributions you receive are still taxable as capital income tax in Switzerland. You must declare the income in your Swiss tax return. If the foreign country withheld tax on the distribution, you may be able to reclaim part of it using the DA-1 form, depending on the applicable double taxation agreement.
Accumulating vs Distributing Funds
A common misconception: choosing an accumulating money market fund (one that reinvests income rather than distributing it) does not eliminate the tax obligation. In Switzerland, even reinvested income is taxable. The fund reports the reinvested amounts to the SFTA, and you are required to declare them. The tax treatment is essentially the same whether income is paid out or reinvested.
Wealth Tax on Money Market Holdings
Beyond income tax, Switzerland also levies a net wealth tax at the cantonal level. This applies to the total value of your assets — including the balance in your money market account or the market value of your money market fund units — as of 31 December each year.
Wealth tax rates vary by canton. In Geneva, the rate ranges from approximately 0.149% to 0.383% on net wealth above the personal deduction threshold (CHF 82,200 per adult in 2025/2026). In Zurich, the rate starts at 0.05% and rises to 0.30% for very large estates. For most investors with modest money market balances, the wealth tax impact is small — but it is still a real cost to factor in.
Importantly, your money market account balance and fund holdings must be declared in the wealth section of your tax return — not just the income section. Failing to declare assets (even if they generate little income) can result in penalties and the forfeiture of your withholding tax refund.
What If You're an Expat or Non-Resident?
For expats living in Switzerland, the rules are the same as for Swiss nationals — you declare your worldwide income and assets, including money market accounts held abroad. Switzerland taxes residents on their global income, so a money market account held in France, Germany, or the UK must also be declared.
For non-residents who hold Swiss money market accounts, the 35% withholding tax is generally a final tax — unless your country of residence has a double taxation agreement (DTA) with Switzerland. Under many DTAs, non-residents can apply for a partial refund of the Swiss withholding tax. The refund amount depends on the specific treaty, but it is typically between 15% and 35% of the gross interest.
If you are on a B permit and earn under CHF 120,000, your taxes may be withheld at source (impôt à la source). In that case, investment income from Swiss accounts is still subject to the 35% anticipatory tax, but the interaction with your source tax can be complex. It is worth getting professional advice to ensure you are not overpaying.
Capital Gains vs Interest: What's Taxable?
One of the most common points of confusion around money market accounts is the distinction between interest income and capital gains.
Interest income from a money market account is always taxable in Switzerland. It is treated as ordinary income and added to your total taxable income for the year.
Capital gains from selling money market fund units at a profit are generally tax-free for private investors in Switzerland. If you buy money market fund units at CHF 100 and sell them at CHF 102, the CHF 2 gain is not taxable — as long as you are classified as a private investor, not a professional trader.
However, if you are classified as a professional trader — based on criteria such as high trading frequency, use of leverage, or deriving most of your income from trading — capital gains become fully taxable. For a deeper look, see our guide on short-term capital gains tax in Switzerland.
In summary: the interest your money market account earns is taxable. The gain from selling fund units is usually not — but the income generated within the fund always is.
How to Declare Money Market Income in Switzerland
Declaring money market income correctly is straightforward once you know the steps. Here is what to do:
Step 1 — Collect your tax certificates
Your bank or fund manager will issue an annual tax certificate (Steuerausweis) showing gross interest earned and withholding tax deducted. Gather these for all accounts and funds.
Step 2 — Declare the gross interest
In your cantonal tax return, report the full gross interest amount (before withholding) in the income section. Do not report only the net amount you received.
Step 3 — Declare the account balance
In the wealth section, declare the balance of your money market account or the market value of your fund units as of 31 December. This is required for wealth tax purposes.
Step 4 — Claim the withholding tax refund
In the withholding tax section of your return, enter the amount of anticipatory tax deducted. This will be offset against your cantonal and municipal taxes, and any excess will be refunded.
Step 5 — Use the DA-1 form for foreign funds
If you hold foreign money market funds and foreign withholding tax was deducted, complete the DA-1 form to claim a credit against your Swiss tax liability.
The deadline for filing your Swiss tax return is generally 31 March of the following year, though most cantons grant extensions on request. In Geneva, extensions are typically available until 30 June or later.
Tax Planning Tips for Money Market Investors
While money market accounts are not the most complex investment from a tax perspective, a few smart habits can make a real difference:
1. Always declare — even small amounts
There is no minimum threshold below which interest income is exempt from declaration in Switzerland. Even CHF 10 in interest must be declared. The benefit is that you also reclaim the 35% withholding on that amount.
2. Consider your canton
The effective tax rate on interest income varies significantly by canton. Geneva, Vaud, and Zurich have different income and wealth tax rates. If you are planning a large money market investment, the cantonal tax impact is worth considering.
3. Use Pillar 3a for tax-sheltered savings
If your goal is to earn a return on short-term savings while minimising tax, consider maximising your Pillar 3a contributions first. The 2026 maximum is CHF 7,258 for employed individuals. Growth inside Pillar 3a is tax-free, and contributions reduce your taxable income.
4. Keep records for three years
The right to claim a withholding tax refund expires three years after the end of the calendar year in which the income was earned. Keep your tax certificates and bank statements for at least this long.

FAQ
Yes. Interest earned on a money market account in Switzerland is subject to the 35% anticipatory tax (withholding tax) at source, and must be declared as income in your annual tax return. Swiss residents who declare correctly can reclaim the 35% withholding and pay only their actual marginal income tax rate on the interest earned.
