Complete Swiss Tax Deductions Checklist 2026: What Expats Can Claim

Employment-related deductions

Professional expenses are the first block of deductions every employed expat should check. The typical flat-rate deduction is automatically granted by most cantons — CHF 2'000 to CHF 4'000 depending on the canton — even without receipts. If your actual costs are higher, claim the higher amount with documentation.

Commuting costs between home and your workplace are deductible. Rules vary by canton, but national rules allow public transport passes, bicycle costs, and, where no public transport exists, car mileage at a fixed rate per kilometre. If you use a GA travelcard for work travel, the business portion is deductible.

Meal costs are partly deductible when work prevents you from eating at home. The nationwide deduction is typically CHF 3'200 per year for full-time work. Shift workers and long-distance commuters may qualify for higher allowances.

Other employment deductions include: continuing education related to your current role, work-related relocation if required by your employer, and home-office costs for regular remote work with a dedicated workspace.

Insurance and health deductions

Health and accident insurance premiums are deductible up to a federal ceiling that rises by canton and family situation. For a single person without children, the maximum under national rules is around CHF 1'700 per year for basic coverage. Married couples and families receive higher ceilings.

The deduction covers mandatory basic health insurance (LAMal/KVG), supplementary hospital cover, and accident insurance premiums. Contributions to AHV/AVS, IV/AI, and EO/APG are also included.

Life insurance premiums are deductible only to a separate, lower ceiling. Savings interest is taxable income, but the insurance premium deduction is a separate fixed allowance against taxable income.

For expats, the important detail: deductions apply against your total taxable income. If you are taxed at source and your income triggers mandatory ordinary assessment, these deductions become especially valuable. The health insurance tax deductions guide covers the health-specific rules in depth.

Pension and Pillar 3a deductions

Pillar 3a contributions are among the most powerful deductions for employed expats. For 2026, the maximum is CHF 7'258 if insured through a pension fund. Without a pension fund, the limit is 20% of earned income, capped at CHF 36'288. This deduction reduces your federal, cantonal, and municipal tax all at once.

Voluntary second-pillar buybacks (Einkauf/rachat) are also deductible. They let you fill missing years in your occupational pension plan. The deduction is often large, but the money is locked until retirement or a qualifying withdrawal event.

The same deduction rules apply across cantons, but the effective value depends on your marginal tax rate. The Pillar 3a maximum contribution guide and Pillar 3a canton savings comparison help estimate the real benefit.

For expats considering leaving Switzerland: Pillar 3a and second-pillar deductions lock your money. The short-term tax benefit must be weighed against withdrawal rules, taxes, and lock-up periods described in the exit Switzerland checklist and Pillar 3a withdrawal guide.

Self-employed expats without a pension fund can deduct up to 20% of net earned income into Pillar 3a, reaching CHF 36'288 in 2026. However, the full amount is locked, so contributions should match your retirement and liquidity plans.

Family and child deductions

Childcare costs are deductible nationwide up to CHF 25'800 per child per year for children under 14. This covers crèche, daycare, and after-school care with receipts from a recognised provider.

A child deduction of CHF 6'800 per child on the federal return reduces taxable income regardless of actual spending. Most cantons add their own child deductions on top, and the combined sum can be substantial. Parents with shared custody should agree who claims the deduction.

For married couples, the dual-earner deduction applies when both spouses work. The nationwide deduction equals 50% of the lower income, capped at CHF 13'400. This partly offsets the marriage penalty. The individual taxation reform guide explains upcoming changes.

Education costs — private school fees, tutoring, school materials — are deductible in several cantons but not on the federal return. Check your canton's rules.

Debt, donations, and other deductions

Interest on personal debt is deductible up to taxable investment income plus CHF 50'000. The most common case is mortgage interest on your primary home. The imputed rental value abolition guide explains how mortgage deductibility changes after 2029.

Donations to Swiss tax-exempt organisations are deductible up to 20% of net income. Both cash and in-kind gifts count with receipts from recognised charities. Political party donations are also deductible from federal tax within limits.

Medical and dental costs are not deductible from federal tax, but several cantons allow deductions for high out-of-pocket health costs, disability-related expenses, and prescribed treatments exceeding a threshold. Keep all receipts and check your canton's rules.

Support payments to dependent relatives — alimony and child maintenance — are deductible from federal tax. If you support parents or children abroad, these payments may qualify under double-taxation agreements. Documentation requirements are strict.

Cantonal special deductions

Several cantons offer deductions unavailable under federal rules. Zurich allows a public-transport commuting deduction above a threshold. Geneva has generous childcare and family deductions. Zug offers a significant tax credit for high-value deductions. Basel-Stadt handles renovation costs for homeowners more favourably than other cantons.

If you moved cantons during the tax year, the moving cantons guide explains how deductions are split and reported across cantonal tax offices.

Also check your specific municipality — communal tax multipliers and local deductions can differ significantly within the same canton. The official ESTV tax calculator or your cantonal tax software is the most reliable tool for a precise pre-filing calculation.
