Swiss Withholding Tax 2026: CHF 153 or CHF 593 – Same Salary, Different Canton
You open your first payslip in Switzerland – and a third is missing. Welcome to withholding tax. Over a million people pay it. Most don't know they could recover thousands of francs.
👤 Who pays withholding tax?
Withholding tax is levied on the salary of all foreign employees without a C settlement permit. Specifically: B permit (residence), L permit (short-term), G permit (cross-border). Weekly residents, artists and athletes without domicile in Switzerland are also affected.
C permit holders or those married to a Swiss citizen or C permit holder do not pay withholding tax — they file a regular tax return instead. Withholding tax is deducted directly from salary by the employer.

💰 Retroactive ordinary assessment: get money back
Since the 2021 reform, every person subject to withholding tax can apply for a retroactive ordinary assessment — even below CHF 120,000 gross income. Above CHF 120,000, it is mandatory. You then file a regular tax return and can claim all deductions.
Warning: the application cannot be withdrawn and applies to all subsequent years. Calculate first whether it is beneficial for you.
⏰ Deadline March 31
Deadline March 31 — not extendable
The application for the previous year must reach the cantonal tax office by March 31 at the latest. This deadline is absolute — no extension, no exception. Miss it and you lose money. If leaving Switzerland, the deregistration date applies.
👨👩👧👦 Case study: the Yilmaz family, tariff B2, canton of Zurich
Mehmet Yilmaz (B permit) works as a mechanical engineering technician in Winterthur. CHF 7,500 gross, married, 2 children, wife not employed. Tariff B2. Without retroactive assessment he simply pays the withholding tax — with it, the family saves over CHF 4,000 per year.
In 5 years without retroactive assessment, the Yilmaz family would have given away over CHF 20,000. The effort: one evening for the tax return.
The same engineer with CHF 8,000 gross salary pays CHF 248 in Zug, CHF 952 in Neuchâtel in withholding tax — per month. That's CHF 8,448 difference per year. Just because of the postcode.

Withholding tax is the biggest tax blind spot in Switzerland. Over a million people pay it — but very few exercise their right to retroactive ordinary assessment. This means: thousands of francs in deductions (pillar 3a, professional expenses, insurance) go unclaimed every year.

If you're subject to withholding tax and miss the March 31 deadline, you cannot claim any deductions for the entire tax year — including pillar 3a (CHF 7,258). That's easily CHF 1,000–2,000 lost per missed year.

Wir haben 2 Kinder und mein Mann arbeitet nicht. Tarif B2 also. Durch die NOV haben wir letztes Jahr über CHF 3'000 zurückbekommen. Lohnt sich mega wenn man Familie hat!
Je travaille à Bâle comme frontalier. L'article explique bien les différences. Pour les frontaliers français, c'est encore un autre système... kompliziert 😅
Guter Überblick. Kleine Ergänzung: Als Konfessionslose habe ich die Kirchensteuer-Korrektur beantragt und spare jetzt CHF 40/Monat. Das wissen viele nicht.
Super Tipp! Die Kirchensteuer-Korrektur ist tatsächlich einer der einfachsten Wege zu sparen. Wer auch als Wochenaufenthalter Steuern optimieren will: Unterkunft, Verpflegung und Fahrkosten bringen bis CHF 18'000 Abzüge.
Ich zahle seit 4 Jahren Quellensteuer und habe NOCH NIE eine NOV beantragt. Hab gerade nachgerechnet, mir fehlen mindestens CHF 8'000 an Abzügen. Danke für den Artikel, das wusste ich nicht!
