Why is the federal rate applied to profit after tax, not pre-tax profit?

Swiss law defines the federal corporate tax base as net profit after the tax itself has been deducted (a circular calculation). The statutory 8.5% on after-tax profit is mathematically equivalent to approximately 7.83% on pre-tax profit (8.5 ÷ 108.5). This calculator handles that conversion automatically.

What does the cantonal rate include?

The cantonal rate shown is the typical combined effective rate for that canton including both the cantonal tax and the communal (municipal) tax for the main business center (e.g., Zug city for Zug, Zurich city for Zurich). Communes within a canton can vary slightly.

Does Switzerland have a minimum tax or surcharge?

Some cantons impose a minimum tax (Minimalsteuer) on equity or gross assets for low-profit years. This calculator covers the income-based levy only; minimum taxes are not modeled.

Is the OECD Pillar Two 15% global minimum tax factored in?

Switzerland enacted the OECD Pillar Two top-up tax effective 2024. Multinationals with consolidated revenues above EUR 750 million may face a supplementary federal top-up levy. This tool covers the standard domestic corporate tax only and does not compute Pillar Two top-up amounts.

Are capital gains taxed differently for companies?

Capital gains realized by Swiss companies on the sale of qualifying participations (shareholdings of ≥10% held for ≥1 year) may benefit from participation exemption (Beteiligungsabzug), reducing the taxable base significantly. This calculator treats all income as ordinary business profit.

Can I use this for a sole proprietorship or partnership?

No. Sole proprietors and general partnerships are taxed at the individual level under Swiss income tax, not corporate tax. This tool is for corporations (AG/SA, GmbH/Sàrl, cooperatives) only.
