Filling in your tax return: guide
Filing a Swiss tax return is mainly a matter of gathering the right documents and claiming every deduction you are entitled to. Here is the step-by-step approach.
How it works
Gather your documents
Collect your salary certificate, bank and securities statements, receipts and any documents supporting deductions.
Check your deductions
Go through deductible items such as pillar 3a contributions, commuting costs, professional expenses and insurance premiums.
Fill in the form
Enter your income, assets and deductions accurately in the cantonal tax form or online tool.
Request a deadline extension if needed
If you cannot file in time, request an extension from the tax office — this is usually granted without difficulty.
Submit the return
Check everything for completeness and submit the return with all required attachments by the deadline.
We'll take care of it
Answered in short
What documents do I need for my tax return?
Typically your salary certificate, bank and securities statements, pillar 3a confirmations and receipts for deductible expenses. The more complete your documents, the more deductions you can claim.
Can I get more time to file?
Yes. Most cantons grant a deadline extension on request, often online. It is better to ask for an extension than to file late.
