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 Schwyz
Two changes for 2026: the Steuerfuss goes from 115% to 110%, and the revised tax law raises deductions, shifts the brackets up by roughly 10% to offset cold progression, and cuts the maximum rate on lump-sum pension payouts from 2.5% to 1.5%.
Official figures and deadlines — Canton Schwyz
Tax multiplier (canton and capital)
The cantonal Steuerfuss falls to 110% for 2026, from 115%. In the town of Schwyz the commune charges 140% and the district (Bezirk) another 35%, so 175% locally — 26 of the 30 communes have that district layer, and quoting the 140% alone understates your bill by 35 points. Together that is 285% without church tax.
Tax return filing deadline
The ordinary filing deadline is 31 March, and any extension has to be requested before that date.
Deadline extension
Request it at efristen.sz.ch before 31 March and pick an end date between the end of July and 31 December at the latest. No fee is published for the extension.
