How Does Swiss Corporate Tax Work?

Swiss corporate taxation operates on three levels, each adding to the total burden:

1. Federal Profit Tax (Direkte Bundessteuer)

The federal government levies a flat 8.5% tax on net profit for all corporations (AG, GmbH). This rate is the same everywhere in Switzerland and has not changed in decades. It is calculated on profit after deducting the tax itself, producing an effective rate of approximately 7.83%.

2. Cantonal Profit Tax (Kantonale Gewinnsteuer)

Each of the 26 cantons sets its own profit tax rate. This is where the biggest differences arise. Cantons like Zug and Nidwalden keep rates low to attract businesses, while Bern and Zurich charge significantly more.

3. Communal Tax (Gemeindesteuer)

Most cantons allow municipalities to levy an additional multiplier on the cantonal tax. A company registered in the city of Zurich pays a different communal rate than one registered in a rural Zurich municipality. The communal multiplier can add 1 to 5 percentage points to the effective rate.

Capital Tax (Kapitalsteuer)

In addition to profit tax, most cantons levy a small annual tax on equity capital (share capital + reserves). Rates typically range from 0.01% to 0.5%. Some cantons (e.g. Zurich, Lucerne) allow companies to offset capital tax against profit tax.

Switzerland offers several legitimate mechanisms to reduce corporate tax:

  • Canton selection — The single biggest lever. Moving from Bern (~21%) to Zug (~11.9%) nearly halves the tax rate.
  • Patent box — Cantons offer reduced rates on income from qualifying intellectual property (OECD-compliant since TRAF 2020).
  • R&D super-deduction — Up to 150% deduction on qualifying research and development expenditure.
  • Notional interest deduction (NID) — Canton of Zurich and others allow a deduction on surplus equity.
  • Holding company relief — Participation exemption on dividends and capital gains from qualifying subsidiaries (minimum 10% stake or CHF 1 million).

For detailed guidance on these mechanisms, see our corporate tax guide.

Frequently Asked Questions

How is corporate tax calculated in Switzerland?
Corporate tax in Switzerland has three levels: federal (8.5% on profit), cantonal, and communal. The cantonal and communal rates vary significantly. The combined effective tax rate ranges from about 11.9% in Zug to over 21% in some municipalities.
Which canton has the lowest corporate tax rate?
As of 2026, Zug has the lowest effective corporate tax rate at approximately 11.9%, followed by Nidwalden (11.97%) and Appenzell Innerrhoden (~12.7%). These cantons actively compete for corporate registrations.
Is the ESTV tax calculator free to use?
Yes. The official Swiss Federal Tax Administration (ESTV/FTA) provides a free online tax calculator that computes the tax burden for any municipality in Switzerland. No registration is required.
Does the tax rate depend on the type of company?
The federal profit tax rate of 8.5% applies equally to all corporations (AG, GmbH). However, holding companies and companies benefiting from patent box regimes may qualify for reduced cantonal rates. Sole proprietorships (Einzelfirma) are taxed as personal income.
How does the Swiss patent box regime reduce corporate tax?
The patent box regime, introduced as part of the Federal Act on Tax Reform and AHV Financing (TRAF) in 2020, allows cantons to reduce cantonal tax on qualifying IP income by up to 90 per cent. Qualifying income includes revenue from patents, software copyright, and similar rights developed or acquired by the company. Each canton implements the patent box slightly differently, but in Zug a company with an effective rate of 11.9% could see its rate on IP income fall to approximately 1 to 2%. The federal 8.5% rate still applies in full. Companies must apply the patent box at the cantonal level and track IP income separately in their accounts.
What is the capital tax in Switzerland and how is it calculated?
In addition to profit tax, most Swiss cantons levy an annual capital tax (Kapitalsteuer) on a company's equity, which includes share capital, retained earnings, and reserves. Rates typically range from 0.01% to 0.5% of taxable equity per year. Some cantons — including Zurich and Lucerne — allow companies to offset capital tax payments against profit tax, so that a company paying substantial profit tax owes little or no capital tax. For a company with CHF 1 million in equity in Zug, the capital tax is approximately CHF 1,000 to CHF 2,500 per year.
Do foreign companies with Swiss subsidiaries pay withholding tax on dividends?
Yes. Switzerland levies a 35% withholding tax (Verrechnungssteuer) on dividends paid by Swiss companies to shareholders. For foreign shareholders, the effective rate depends on the applicable double taxation agreement (DTA) between Switzerland and the shareholder's country of residence. Under many DTAs — including those with Germany, the United Kingdom, and the United States — the withholding tax rate is reduced to 15% for portfolio investments or 5% for qualifying participations. Shareholders must apply for a refund or reduction through the Federal Tax Administration. Companies in DTA-exempt structures may also benefit from full relief.
How does the ESTV tax calculator work and what information do I need?
The official ESTV Steuerrechner at swisstaxcalculator.estv.admin.ch calculates the combined federal, cantonal, and communal tax burden for any Swiss municipality. You enter the taxable profit, taxable capital, and the specific municipality, and the tool returns the precise amounts due at each level. No registration is required and the tool is free. The underlying data is updated annually using the official cantonal and communal tax rates published by the Federal Tax Administration. The calculator covers both corporate (AG, GmbH) and individual taxpayer scenarios.
Can Swiss corporate tax rates change, and how often are they updated?
Yes. Cantonal and communal tax rates are set by cantonal parliaments and communal assemblies and can change annually. Cantons sometimes announce multi-year rate reductions to attract businesses: Geneva, for example, cut its effective rate significantly between 2020 and 2024 as a result of the TRAF reform. The federal rate of 8.5% has been stable for decades and would require a constitutional amendment to change. The ESTV publishes updated tax burden statistics each year, and the figures in this calculator reflect the most recently available official data.
What is the effective vs nominal corporate tax rate in Switzerland?
The nominal rate is the statutory rate applied to taxable profit before any adjustments. The effective rate accounts for the fact that Swiss corporate tax is itself deductible as a business expense: because the federal tax of 8.5% is levied on profit net of the tax itself, the actual effective federal rate is approximately 7.83%. The combined effective rate quoted for each canton — such as 11.9% for Zug — represents the total burden on pre-tax profit after all three levels (federal, cantonal, communal) are considered and the deductibility of taxes is reflected. This is the figure most useful for comparing jurisdictions and for financial planning purposes.
