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

Official figures and deadlines — Canton Grisons
Tax multiplier (canton and capital)
The cantonal Steuerfuss for 2026 is 92%, cut from 95% in 2025. The city of Chur adds a communal Steuerfuss of 88%.
Tax return filing deadline
Self-employed people have until 30 September of the following year — six months more than the 31 March that applies to employees. It is one of the most comfortable filing calendars in Switzerland for a solo business.
Deadline extension
If you are self-employed you must ask by 20 January of the second following year for a single, non-extendable extension to 31 May at the latest. Approval is tacit and there is a tolerance until 31 January; no fee is published for it.
