Geneva tax calendar
Geneva tax deadlines, in plain English.
The Administration fiscale cantonale (AFC) sets a yearly filing window for residents of the canton of Geneva. Here's what expats actually need to track — and when to ask for an extension before it costs you.
Replies are typically sent within one business day. Introductions are reviewed manually in Geneva.

Local context
What to know in Geneva
- Ordinary deadline
- Geneva tax returns are due by 31 March for the previous tax year. Extensions are routinely granted but must be requested before the deadline.
- Quasi-resident request (TOU)
- If you're taxed at source and want ordinary taxation, the request to AFC Genève must be filed by 31 March of the year following the tax year.
- Free extensions
- A first extension to 30 September is usually granted online without justification. Further extensions to 30 November / 28 February require a reason.
- Sommation & penalties
- If you miss the extended deadline AFC issues a sommation (CHF ~40). Repeated non-filing leads to a taxation d'office — almost always worse than filing late.
- Frontaliers
- French residents working in Geneva on the 4.5% accord still receive a tax certificate and may need to file in France — coordinate both sides.
- First Swiss filing
- Newly arrived B permit holders earning above CHF 120,000 gross are taxed at source AND must file an ordinary return. Don't skip the second step.

FAQ
Common questions
What if I arrived mid-year?
You file for the period from your arrival to 31 December. Income earned before arrival in Switzerland is generally not declared, but is used to determine the rate (taux global).
Do I lose deductions if I file late?
No — deductions remain available as long as you file. A taxation d'office, however, is estimated by AFC and typically ignores deductions, so always file even if late.
Can my fiduciaire request the extension for me?
Yes. Listed fiduciaires can request collective extensions on behalf of their clients, often pushing the effective deadline well into autumn.
