Home office deduction
No fixed cap
If you work from home regularly and have a dedicated workspace, you can deduct a share of rent/mortgage interest, utilities, and insurance proportional to the office area.
Professional tools and training
No fixed cap
Deduct software subscriptions, hardware, books, courses, and conference fees directly tied to your business activity.
Vehicle / travel expenses
No fixed cap
Deduct business travel at CHF 0.70/km (car) or actual public transport costs. Keep a logbook for mixed-use vehicles.
Meal deduction (away from home)
No fixed cap
When working at a client site or traveling for business, deduct CHF 15/meal for lunch and CHF 27.50 for dinner.
Health insurance premium deduction
Max: CHF 6’600
Health and accident insurance premiums are deductible up to a canton-specific cap for self-employed persons.
Canton note: Bern: max CHF 6,600 for single taxpayers (2025).
Interest on business loans
No fixed cap
Interest paid on loans used exclusively for business purposes (equipment, working capital) is fully deductible.
Applies from CHF 50’000 revenue
Pillar 3a buy-in for a missed year (new)
Max: CHF 7’258
2026 is the first year you can buy back a Pillar 3a gap (2025). Pay the full 2026 contribution first, then buy in up to CHF 7'258 extra — both fully deductible. Requires a written application to your 3a foundation.
Pillar 3a contribution (with 2nd pillar)
Max: CHF 7’258
Contribute the maximum to your Pillar 3a account before Dec 31. This amount is fully deductible from taxable income.
Pillar 3a contribution (without 2nd pillar)
Max: CHF 36’288
As a self-employed person without a 2nd pillar, you can contribute up to 20% of net income (capped). This is the single most impactful deduction.
Pay provisional AHV before year-end
No fixed cap
AHV/IV/EO contributions paid in the current year are deductible for that year. Ensure your provisional contributions are paid before Dec 31.
Immediate asset write-off
Max: CHF 1’000
Assets under CHF 1,000 can typically be expensed immediately. For larger items, use declining-balance depreciation (often 25-40% per year depending on asset class).
VAT method optimization
No fixed cap
If your expenses are below ~40% of revenue, the flat-rate method (taux de dette fiscale nette) often saves money vs. effective method. Review annually.
Requires VAT registration
What changes in 2026 in Bern
For 2026 Bern only adjusts the tariff for cold progression (+0.6%) and raises the mileage rate from 70 to 75 centimes; the pillar 3a buy-in is available. A wider tax revision was passed on 16 March 2026 but takes effect from 2027 onwards, with an income-tax cut of about 3%.
Official figures and deadlines — Canton Bern
Tax multiplier (canton and capital)
Bern works in units (Steueranlage): the canton charges 2.975 units for 2026, unchanged from 2025. The city of Bern adds 1.54 units — a figure untouched since 2010 — for a combined 4.515 units, plus roughly 0.19 for church tax.
Tax return filing deadline
Self-employed people have until 15 May, two months more than the 15 March that applies to employees. The later date covers everyone who files business accounts with the return.
Deadline extension
Extensions run to 15 November at most: free online to 15 July, CHF 20 to 15 September and CHF 40 to 15 November, with CHF 20 extra each time if you ask on paper or by phone. A missed deadline costs a CHF 60 reminder fee.
What is specific to Bern for the self-employed
Particularity 1
The insurance-premium deduction is CHF 2'450 single and CHF 4'900 married, but it jumps to CHF 3'600 and CHF 7'200 if you pay into neither a pension fund nor pillar 3a, plus CHF 700 per child. Many self-employed people qualify for the higher figure.
Particularity 2
Wealth tax is capped at 25% of the yield on your wealth, with a floor of 2.4 per mille. For self-employed people the yield includes an imputed interest on business assets, itself capped at your self-employment income (Art. 66 StG).
Particularity 3
There is no separate home-office deduction: you claim the actual costs of the workroom, and for the days you work at home you cannot also claim commuting and meal deductions.
Particularity 4
Childcare is deductible up to CHF 16'000 per child under 14 for cantonal tax, well below the federal cap of CHF 25'800.
