Accounting firm in Geneva
This is where we are based, and it is the canton whose administrative practice we know best.
Withholding tax, International Geneva and cross-border staff
A large share of taxpayers taxed at source
Geneva concentrates a large share of the people taxed at source in French-speaking Switzerland: B and L permit holders, cross-border commuters, staff of international organisations. It is also the canton where corrections and subsequent ordinary assessments are most frequent.
International organisations, NGOs and permanent missions
These institutions and their staff form a concentration that exists nowhere else in Switzerland, with their own residence statuses and tax regimes. English is the working language of much of it.
Staff living in France
A share of the staff of Geneva companies live in France. The applicable regime depends on the agreement with the country of residence, and the rules on remote work have changed recently.
The Geneva tax administration, its deadlines and tariffs
In Geneva, tax matters are handled by the Cantonal Tax Administration (AFC). For the returns concerned, the ordinary filing deadline is 31 March. An extension can be requested through your online tax account (espace fiscal), the online form or by telephone until 31 October; after that, a reasoned request must be sent by post.
Extensions are charged: CHF 20 for up to 3 months, CHF 40 for up to 5 months and CHF 60 beyond.
To challenge a tax assessment notice, an objection must be filed within 30 days of receipt, for cantonal and communal tax (ICC) as well as federal direct tax (IFD).
The 2026 Geneva withholding tax tariffs are published by the AFC on ge.ch, as PDF files, a calculator and ASCII files, without church tax.
