Guides
Short guides to help you understand your Geneva tax return. Each one ends with the official pages, which have the final word.
Your documents: what to gather, and where to find them
The papers your return needs, which ones to attach and which to keep, and the 31 March deadline.
Pillar 3a: pay in before 31 December
What you pay into pillar 3a lowers your taxable income, but only if the money is paid in during the year.
Taxed at source: ordinary taxation afterwards (TOU)
How TOU works, when it’s mandatory, the 31 March deadline, and why you can’t go back.
Filing as a couple
Married or in a registered partnership: one return, who fills in what, and how Geneva sets the rate.
Your assessment (avis de taxation), and how to object
What you receive after filing, how to check it, and how to object (réclamation) within 30 days.
Your data stays on your computer
What Taxpresso keeps on your computer, what Claude sees, and how to set Claude’s privacy settings.
