Giving TL Fiduciaire a mandate (Geneva)

Version of 23 October 2026. Geneva tax administration procedure, to be rechecked before each campaign.

1. TL Fiduciaire prepares the mandate request from its professional representative account, with your tax reference (Rxx.xxx.xxx) and your AHV13 number, sent through your secure area.
2. You receive an e-mail invitation (if you are registered with e-démarches) or a letter from the administration.
3. You approve the request in your own e-démarches area, or you sign and return the letter, which contains an activation code.
4. TL Fiduciaire checks that the mandate is active and informs you in your area.
5. You approve the procedure to file; the official filing proof will be added to your area.

Scope and revocation

For an individual, the e-démarches mandate gives the representative access to all your online tax services. You can revoke it at any time from your e-démarches area or by writing to the administration; please tell us too.

Three codes not to confuse

• The mandate activation code (letter): send it only through your secure area.
• The e-filing codes of your return: add them to your area as soon as you receive them.
