Key Switzerland terms
View full glossaryGewinnsteuer
Gewinnsteuer is Switzerland's corporate profit tax. At the federal level, the direct federal tax (direkte Bundessteuer) is levied at a flat rate of 8.5% on profit after tax, which equates to an effective rate of approximately 7.83% on pre-tax profit. Cantons levy their own Gewinnsteuer on top, meaning the combined federal and cantonal effective rate varies by canton.
Kapitalsteuer
Kapitalsteuer is a cantonal tax levied on a company's net equity (paid-in capital plus reserves plus retained earnings). It is a purely cantonal and communal tax — there is no federal Kapitalsteuer. Rates are low (typically 0.001 to 0.5% of net equity annually) but it is a recurring annual cost even in loss years.
MWST / TVA (Mehrwertsteuer)
MWST (Mehrwertsteuer in German, TVA in French, IVA in Italian) is Switzerland's value added tax. The standard rate is 8.1%, with a reduced rate of 2.6% for food, books, newspapers, medicines and certain agricultural goods, and a special rate of 3.8% for accommodation services. VAT registration is mandatory for businesses with annual turnover exceeding CHF 100,000.
GmbH (Gesellschaft mit beschränkter Haftung)
A GmbH (Société à responsabilité limitée / Società a responsabilità limitata) is Switzerland's most common private limited company form. It requires a minimum share capital of CHF 20,000, all of which must be paid up on formation. Liability is limited to the company's assets. It is governed by the Swiss Code of Obligations (OR/CO), Articles 772–827.
AG (Aktiengesellschaft)
An AG (Société anonyme / Società anonima) is Switzerland's public limited company form. It requires a minimum share capital of CHF 100,000, of which at least 50% (minimum CHF 50,000) must be paid up on formation. Shares can be issued as registered shares (Namenaktien) or bearer shares (Inhaberaktien, now restricted). Governed by OR Articles 620–763.
Dividendenbesteuerung (Dividend Taxation)
In Switzerland, dividends paid by a company are subject to Verrechnungssteuer (withholding tax) at 35% at source. Shareholders resident in Switzerland can reclaim the full 35% against their personal income tax (Einkommenssteuer). For qualifying corporate shareholders holding at least 10% of share capital (or participation worth CHF 1 million), a Beteiligungsabzug (participation deduction) effectively exempts most dividend income at the corporate level.
Can I claim it? Switzerland expenses
All expensesHome Office (Heimbüro)
PartialPartially deductible for Swiss companies when a proper, dedicated workspace is used exclusively for business and no other office is available. Rules are strict — mixed-use rooms are generally disallowed. Cantonal rules vary slightly.
Business Travel (Geschäftsreisen)
YesFully deductible for genuine business travel including flights, trains, hotels, and meals when away from base. Switzerland has clear ESTV guidelines on permissible expense rates. Personal or holiday components must be excluded.
Client Entertainment (Kundenbewirtung)
Partial50% deductible for client meals and entertainment under Swiss tax law. The 50% restriction aligns Switzerland with many other jurisdictions. Business meals between directors only (no client present) may be disallowed entirely.
Mobile Phone & Internet (Telefon & Internet)
YesFully deductible when used primarily for business. Where a phone or broadband is used for both business and private purposes, the business proportion (typically 80% for a primary business phone) is deductible. Employer-provided phones under CHF 1,500 are generally not taxed as a benefit-in-kind.
Office Equipment & Computers (Büroausstattung & Computer)
YesFully deductible. Computer equipment, office furniture, and business equipment used for the company are deductible either in full in the year of purchase (for low-value items) or depreciated over their useful life. Swiss depreciation rates are published by the ESTV.
Business Software & SaaS Subscriptions
YesFully deductible. SaaS subscriptions (accounting software, CRM, productivity tools) paid periodically are expensed in full in the year of payment. Purchased software licenses are depreciated over 3 years.
Switzerland tax deadlines
All deadlinesFederal & Cantonal Corporate Tax Return (Steuererklärung juristische Personen)
The annual corporate income tax return filed with the cantonal tax authority, covering both the direct federal tax (Direkte Bundessteuer / DBSt) and cantonal and communal taxes (Staats- und Gemeindesteuer / StGSt). A single return filed with the canton covers all three levels of Swiss corporate tax.
MWST Quarterly Return (MWST-Abrechnung vierteljährlich)
The quarterly value added tax return filed with the ESTV (Swiss Federal Tax Administration) for businesses using the standard effective MWST accounting method. Businesses report output MWST collected, input MWST paid, and remit or reclaim the difference.
Verrechnungssteuer Declaration on Dividends (Form 102)
When a Swiss company pays dividends (or other capital distributions) to shareholders, it must withhold 35% Verrechnungssteuer and declare it to the ESTV within 30 days. Form 102 (Meldung der verrechnungssteuerpflichtigen Leistung) is the declaration of taxable performance subject to withholding.
Monthly AHV/IV/EO/ALV Payroll Declaration
Swiss employers must remit AHV (old-age and survivors insurance), IV (disability insurance), EO (income replacement), and ALV (unemployment insurance) contributions to their cantonal Ausgleichskasse (compensation office) monthly. The employer withholds the employee share and adds the employer share, remitting the combined amount.
