|---|---|
| Public transport | Actual cost (monthly/annual pass) |
| Car (own vehicle) | CHF 0.70/km, maximum CHF 3000 (federal) |
| Bicycle | CHF 700 flat rate |
Important: Some cantons have lower maximums for car commuting (e.g., Vaud: CHF 700). Use public transport costs where possible — they are deductible in full with no cap.
2. Meal costs outside home (Verpflegungskosten)
If you cannot return home for lunch due to work distance or schedule:
- With subsidized canteen: CHF 1,600/year flat rate
- Without canteen: CHF 3200/year flat rate
No receipts required — flat rate applies automatically if work location differs from home.
3. Professional expenses — flat rate (Pauschalabzug Berufskosten)
A flat deduction for general professional expenses (work equipment, professional literature, minor expenses):
- Federal: 3% of net salary, minimum CHF 2,000, maximum CHF 4,000
- Cantons: Similar, amounts vary slightly
This is taken automatically — you can claim more if actual documented costs exceed the flat rate.
4. Professional training and education (Weiterbildungskosten)
Costs for further professional education directly related to your current employment:
- Maximum: CHF 12000 per year (federal; cantons may vary)

| Self-employed without pension fund | CHF 36288 (or 20% of net income) |
The full amount contributed is deductible from taxable income. At a marginal rate of 30%, CHF 7258 saves approximately CHF 2,175 in tax.
B permit holders: Must file NOV to claim this deduction — it is not reflected in withholding tax.
6. Pension fund buyback (Einkauf 2. Säule)
Voluntary contributions to your company pension fund to fill pension gaps:
- No annual limit — up to the regulatory maximum gap amount
- Fully deductible from taxable income

This is one of the most powerful deductions for higher earners — there is no CHF cap on the amount.

12. Relocation costs
- Costs of moving household from abroad to Switzerland
- Return relocation at end of assignment
- Condition: employer must confirm expat status on Lohnausweis

14. International school fees
- Tuition fees for international schools for expat children
- Condition: expat arrangement, temporary stay, children enrolled in international curriculum
- Deductible if employer does not already reimburse the costs
Important: These special expat deductions require the employer to designate the employee as an "expatriate" on the Swiss salary certificate (Lohnausweis, field 15). Without this designation, the deductions are not available.

Frequently Asked Questions
B permit holders can claim all deductions listed here, but only by filing a NOV (Nachträgliche Ordentliche Veranlagung). Withholding tax does not reflect individual deductions. For deductions worth more than a few hundred francs, requesting the NOV is almost always worthwhile.
Yes. Any person living and working in Switzerland with income subject to AHV (social insurance) can contribute to Pillar 3a — including B, C, G, and L permit holders. The maximum in 2025 is CHF 7258 for employees with a pension fund. The deduction is claimed on the NOV or standard tax return.
Yes, but only under specific conditions: the employee must be officially designated as an expatriate on their Swiss Lohnausweis (salary certificate, field 15), the stay must be temporary, and the fees must not already be reimbursed by the employer.
For flat-rate deductions (professional expenses, meals, child deduction) no receipts are needed — amounts apply automatically. For actual-cost deductions (childcare, training, mortgage interest, Pillar 3a) you need receipts or certificates. Your Lohnausweis must correctly reflect expat status if claiming expat-specific deductions.
For an expat earning CHF 120,000 with a family, claiming Pillar 3a (CHF 7258), childcare (CHF 15,000), commuting (CHF 2,400), and professional expenses (CHF 4,000) gives total deductions of approximately CHF 28,700. At a marginal rate of 28%, the tax saving is approximately CHF 8,000 per year.
