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 Lucerne
Tax multiplier (canton and capital)
Lucerne works in units: the canton charges 1.45 units for 2026, cut from 1.55 in 2025. The city of Lucerne adds 1.45 units, for a combined 2.90 units without church tax.
Tax return filing deadline
If you are self-employed you have until 31 August of the following year, and you do not have to ask for it. For employees Lucerne publishes no fixed calendar date: the deadline is printed on the return, the law giving 30 days from delivery (§ 145 StG).
Deadline extension
Extensions are free and self-service online: to 30 November of the following year if you are self-employed, to 31 August if you are an employee. Beyond that you need a written request with serious grounds, and 31 December is the outer limit; a second reminder costs CHF 40.
