Moving canton in Switzerland: what changes for your taxes

Direct answer
For a given calendar year, you are generally taxed in the canton where you have tax residence on 31 December, including communal and church tax there. Federal tax follows the same return, but cantonal and municipal rates, wealth tax, and deductions differ, so a move late in the year can shift the whole year's cantonal bill.
Key facts
- Tax residence on 31 December determines cantonal and municipal taxation for that year.
- You must register and deregister with communal authorities when you move; deadlines are cantonal.
- Wealth tax is cantonal; assets are valued under cantonal rules on the same residence date.
- Church tax (Kirchensteuer) follows cantonal church law and your registered status.
- Provisional tax bills from the old canton may need adjustment after the move.
Timeline in a relocation year
Before moving, keep your last provisional bill and commune multiplier. Register at the new commune on time. Payslip social rates stay the same nationwide: AHV/IV/EO 5.30% and ALV 1.10% up to CHF 148,200.
After 31 December you file for the year; canton of residence on that date is central for cantonal and municipal tax, aside from special short-stay rules.
Worked example: move on 1 October
You live in Canton A until 30 September and in Canton B from 1 October through 31 December.
For many taxpayers the cantonal tax for the entire calendar year is assessed in Canton B because tax residence on 31 December is in B.
You earned CHF 120,000 gross all year with one employer. Mandatory ordinary assessment (NOV) applies from CHF 120,000; you file in B even if most earnings were while living in A.
Municipal and church surcharges use B's rules from the assessment. Update church membership separately if you intend to leave Kirchensteuer; moving alone does not exit the church.
Pillar 3a up to CHF 7,258 with a pension fund remains deductible federally; payment in the same calendar year still controls the deduction.
- 1Deregister at the old commune; keep the confirmation.
- 2Register at the new commune; receive new tax ID if applicable.
- 3Inform employer payroll for communal tax at source if relevant.
- 4Watch for final provisional bills from Canton A and new ones from Canton B.
- 5Prepare the return using the canton of 31 December residence.
Second example: mid-year move and wealth tax
Year-end holdings CHF 80,000 cash and CHF 200,000 shares: Canton B values them for wealth tax if you reside there on 31 December, usually for the full year, not month by month.
Property in another canton may still trigger local property rules. Private share gains remain generally tax-free for private investors.
Cross-border and double moves
Two internal moves in one year still end with one decisive canton for many income tax purposes: where you live on 31 December.
Leaving Switzerland entirely triggers departure tax and reporting rules beyond this article. Internal moves are simpler but still require deregistration.
Quellensteuer holders who cross CHF 120,000 must switch mindset to NOV filing in the year-end canton.
Keep Lohnausweis and 3a confirmations; they are the same documents regardless of canton.
Common mistakes
Assuming the old canton bills income month by month until the move date without checking local law.
Forgetting to deregister and receiving duplicate communal correspondence.
Expecting church tax to stop at the border; exit is a registry act, not an address change.
Paying provisional bills in the old canton after 31 December residence changed without notifying either tax office.
Missing the 31 March deadline for voluntary NOV in the new canton when income is below CHF 120,000 but deductions would help.
FAQ
- Do I pay two cantons in the year I move?
- Usually you file primarily where you reside on 31 December. Special rules may apply for very short stays; check both cantons if you moved near year-end.
- Does church tax stop automatically when I move?
- No. Church membership and Kirchensteuer follow cantonal church law. Leaving a church is a separate step at the registry office.
- Which canton taxes my 3a withdrawal?
- Tax on capital withdrawals is due in the canton of residence at withdrawal, at reduced rates for qualified pillar capital.
- When does NOV matter after a move?
- Mandatory ordinary assessment applies from CHF 120,000 gross nationwide; the canton of 31 December processes the return.

Furthermore, late 2026 marks the preparatory window for the landmark retroactive Pillar 3a buy-in reform, allowing individuals who missed past contribution maximums to purchase retroactive quotas under strict statutory conditions.
- Swiss tax return deductions: a practical checklistPillar 3a contributions up to CHF 7,258 (with a pension fund) or up to 20% of net income capped at CHF 36,288 (without) reduce taxable income if paid in the tax year. Social security on your payslip (AHV/IV/EO 5.30%, ALV 1.10% on wages up to CHF 148,200) is not a separate deduction but shapes your net income for limits like 3a without a pension fund.
- Marginal vs average tax rate in SwitzerlandYour marginal rate is the tax on the last franc of income; your average rate is total tax divided by total income, always lower on progressive scales. Switzerland has no single national income tax percentage: federal tax (DBG Art. 36 ff.), cantonal tax, and municipal multipliers stack, so marginal rates rise in brackets rather than as one flat number.
