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 Obwalden
Tax multiplier (canton and capital)
Obwalden works in units too. For 2026 the canton charges 3.15 units plus a 0.10 unit for flood protection, so 3.25; Sarnen charges 3.76 plus 0.10, so 3.86. With the church unit of 0.54 that comes to 7.65 in total.
Tax return filing deadline
Obwalden sets no fixed calendar date. Your deadline is 60 days from the day you receive the tax notice (Mitteilung), which the canton sends out by the end of February. Dates such as 31 March that circulate on comparison sites are a simplification.
Deadline extension
You can extend to 31 December without giving a reason: free online at efristen.ow.ch, or CHF 30 if you ask in writing. Beyond 31 December you need a justification and pay CHF 30 plus CHF 30 per further quarter.
What is specific to Obwalden for the self-employed
Particularity 1
Obwalden taxes income at a flat cantonal rate of 1.8% (Art. 38 of the tax law) and wealth at a flat 0.2‰. There are no brackets, so an extra franc of profit is taxed at the same cantonal rate as your first.
Particularity 2
From 2026 there is no more suspension of time limits (Fristenstillstand) over the holiday periods, so deadlines run straight through.
Particularity 3
Several reliefs target self-employed people: an R&D deduction, the patent box, privileged taxation of the liquidation gain if you stop at 55 or older or through invalidity, and 50% partial taxation of qualifying business participations.
