Tax deductions in Switzerland: which receipts you need for your tax return
Swiss tax deductions explained: professional expenses, pillar 3a, training, medical costs, donations. Which deductions need receipts and how to collect them all year.
In short: the main Swiss tax deductions are professional expenses, pillar 3a contributions, training costs, insurance premiums, medical costs, donations, childcare and debt interest. Flat-rate deductions need no receipts; every deduction based on actual costs does. You do not have to submit the receipts with your tax return, but you must be able to produce them on request, which is why collecting them all year round pays off.
Every spring the same question comes up: what can you deduct from your taxes in Switzerland, and which receipts do you need for it? The answer depends on your canton, because the federal government and the cantons each have their own rules. The basic structure is the same everywhere, though, and most deductions are relevant to every employee and self-employed person.
This article gives you the overview: which deductions exist, where a flat rate is enough and where you need receipts. The figures refer to direct federal tax as of 2026; the exact cantonal amounts are in your canton's guide to the tax return (the Wegleitung).
Which tax deductions exist in Switzerland?
There are three groups of deductions: income-related costs, general deductions and social deductions. Income-related costs are what you spend to earn your income, above all professional expenses. General deductions are legally permitted expenses such as pension savings or insurance. Social deductions are fixed amounts, for children for example, and need no receipts at all.
The main deductions for private individuals at a glance:
| Deduction | Flat rate or actual | Receipts needed? |
|---|---|---|
| Other professional expenses | Flat rate 3% of net salary, min. CHF 2,000, max. CHF 4,000 | Only if actual costs are higher |
| Commuting costs | Actual, federal max. CHF 3,200 | Public transport pass or mileage proof |
| Pillar 3a | Actual, 2026 max. CHF 7,258 with a pension fund | Certificate from bank or insurer |
| Training and education | Actual, federal max. CHF 13,000 | Invoices and proof of payment |
| Medical costs | Actual, above a 5% threshold of net income | Invoices, pharmacy receipts, health insurer statement |
| Donations | Actual, federal max. 20% of net income | Donation confirmations |
These figures apply to direct federal tax. Cantons have partly different limits, often higher, sometimes lower. Depending on the canton there are further deductions for childcare, insurance premiums, debt interest, alimony, property maintenance and home office.
Professional expenses: when is the flat rate enough and when do you need receipts?
The flat rate is enough if your actual other professional expenses are below 3 percent of your net salary. On a net salary of CHF 80,000 that is CHF 2,400. You get the flat rate without a single receipt. Only if you can prove you spent more, for example on work clothing, professional literature or tools, are the actual costs worth claiming, and then you need every receipt.
Commuting and meals are different: they are not part of that flat rate but separate deductions. For commuting by public transport you need the pass or the tickets; for the car you need a reason why public transport is not reasonable. For meals away from home there is a fixed amount per working day, with no need to keep lunch receipts. All the details, including home office and weekly commuters, are in professional expenses in Switzerland.
A realistic example: you earn CHF 90,000 net, hold a GA travelcard for around CHF 4,000 and eat out at work. Commuting CHF 3,200 (federal, capped at the maximum), meals CHF 3,200, other professional expenses at the flat rate CHF 2,700. Around CHF 9,100 in professional expenses in total, for which you need exactly one receipt: the GA invoice.
Pillar 3a and training: the biggest deductions with the least effort
Pillar 3a is the simplest large deduction: you pay in, the bank sends the certificate, you enter the amount. Employees with a pension fund may pay in up to CHF 7,258 in 2026; self-employed people without a pension fund up to 20 percent of earned income, capped at CHF 36,288. The only receipt is the certificate you receive automatically in January.
Training and education costs are fully deductible too, at federal level up to CHF 13,000 per year, as long as the training is job-related. That includes course fees, exam fees, teaching materials and travel to the course venue. Here you need the invoice from the institution and the proof of payment, and for materials the receipts. Not deductible are the first qualification at upper secondary level and hobby courses. Where the line runs is explained in deducting education and training costs.
If your employer pays part of the cost, you may only deduct the part you paid yourself. So keep the agreement with your employer as well.
Medical costs, donations and childcare: where receipts really decide
For these deductions, your receipt collection decides whether anything is deductible at all. Medical and accident costs can only be deducted to the extent they exceed 5 percent of your net income. On CHF 80,000 net income, only what lies above CHF 4,000 counts. If you add up the deductible, co-payments, dental bills and glasses, an expensive year gets you over that line quickly. Without receipts you cannot prove it.
Collect the following:
- The annual statement from your health insurer showing deductible and co-payments
- Dental invoices, where not covered by insurance
- Pharmacy receipts for prescribed medication
- Invoices for glasses, hearing aids, therapies
- In case of disability: costs not covered elsewhere
Donations to charitable, tax-exempt organisations in Switzerland are deductible at federal level from CHF 100 per year up to 20 percent of net income. The organisation issues a donation confirmation, often only on request. Smaller amounts are documented with the payment record or the e-banking statement.
For childcare by third parties (daycare, day family, after-school care) you need the invoices and proof that both parents work or are in training. The maximum amounts vary considerably between cantons.
How do you collect tax return receipts all year round?
The best way is to collect receipts as they arise, digitally and sorted by category. The mistake almost everyone makes is to hunt for receipts in March and then fail to find the dentist's invoice from February of the previous year.
A simple workflow that works:
- Set up categories that mirror the deductions: professional expenses, training, health, donations, childcare, property.
- Photograph every receipt with your phone as soon as you have it. Belego reads amount, date and merchant automatically and stores the receipt as a PDF; all you do is assign the category.
- Invoices that arrive by email go into the same collection as PDFs.
- In January, export the whole year as a ZIP: PDFs plus a CSV list with category and amount. The annual overview shows you right away whether you clear the threshold for the medical deduction.
You do not submit the receipts with your tax return unless the guide explicitly asks for it (for example for donations or training in some cantons). But the tax office can request them, even years later. How long you should keep them as a private person is covered in keeping receipts as a private person. A complete list to tick off is in the receipt checklist for the Swiss tax return.
Note: this article is general guidance, not tax advice. The law, your canton's guide and the information provided by your tax authority or your Treuhänder (the Swiss term for a trustee or accountant) are what count.
Frequently asked questions
Do I have to submit receipts with my Swiss tax return?
In most cantons no longer, especially when filing electronically. Usually only the salary certificate, the pillar 3a certificate and, depending on the canton, evidence for training, donations or medical costs are required. The tax office can, however, verify any deduction and request receipts. If you cannot produce them, you lose the deduction. So keep every receipt even if you do not submit it.
What can an employee deduct without receipts?
Without receipts you get the flat-rate professional expense deduction of 3 percent of net salary (federal: at least CHF 2,000, at most CHF 4,000), the meal allowance for eating away from home, the insurance deduction up to its flat-rate limit, and the social deductions for children or dependants. Anything beyond that you must be able to prove.
Can I deduct health insurance premiums from my taxes?
Yes, but only up to a limit. Premiums for health, accident and life insurance fall under the insurance deduction, which is capped at a flat amount that varies by canton, marital status and pension fund membership. Actual premiums are usually well above the cap. You do not need receipts, but keep the premium invoice anyway.
Is the medical cost deduction worth the effort at all?
Only in years with high costs. At federal level there is a threshold of 5 percent of net income, and most cantons apply a similar one. If you bundle dental treatment, glasses, therapies and your deductible into one year, you are more likely to clear it. So add up your receipts first, before spending time on filling in the form.
