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.

Official figures and deadlines — Canton Basel-Landschaft
Tax multiplier (canton and capital)
The cantonal Steuerfuss on income is 100% for 2026, within the legal band of 95–105%. Wealth is taxed directly at the statutory rates (1.1, 2.9 and 3.3 per mille above CHF 10'000, CHF 150'000 and CHF 350'000), with no multiplier. Liestal charges a communal 65%, unchanged since 2022; the cantonal average is 59.41%.
Tax return filing deadline
Self-employed people file by 30 June, three months later than the 31 March that applies to employees.
Deadline extension
The first two months of extension are free and tacit — you do not have to ask for them. Any further extension costs CHF 40, and going beyond eight months requires a justified request answered in writing.
What is specific to Basel-Landschaft for the self-employed
Particularity 1
The 20% flat deduction for secondary income (max CHF 2'400) is reserved for employees. If your side activity is self-employed, you must document the actual costs (§ 3 para. 3 StV) — so keep the receipts from day one.
Particularity 2
The insurance-premium deduction is one of the lowest in Switzerland: CHF 2'000 single, CHF 4'000 married, plus CHF 450 per child — half of what neighbouring Basel-Stadt allows (CHF 4'200 / CHF 8'400).
Particularity 3
A start-up relief is possible for the founding year plus the following nine years (§ 17 StG), which can matter a lot in the early years of a business.
Particularity 4
Childcare is capped at CHF 10'000 per child under 14 — far below Basel-Stadt (CHF 26'000) and the federal cap (CHF 25'800).
