How to File Your First Swiss Tax Return as an Employee

Whether you file a tax return at all in your first year depends heavily on your permit type. Many newcomers are taxed at source (withheld directly from salary) and don’t file an ordinary return unless they ask for one, or their income crosses a threshold that requires it.

Step 1: work out whether you’re taxed at source

Permit B holders below a certain income level are typically taxed at source by default, with tax withheld automatically from each paycheck. Permit C holders and Swiss citizens generally file an ordinary return like anyone else. See our permit types guide for how this connects to your specific permit.

Step 2: decide if a correction (Tarifkorrektur) is worth requesting

If you’re taxed at source but have deductible expenses the standard withholding doesn’t account for, Pillar 3a contributions, childcare costs, commuting costs, you can request a correction to reclaim the difference. This has to be requested by a fixed annual deadline, it isn’t automatic.

Step 3: if you do file an ordinary return

• Gather your annual salary certificate (Lohnausweis) from your employer
• Gather Pillar 3a contribution confirmations, they’re directly deductible
• Gather receipts for other deductible costs: commuting, further education, childcare
• File via your canton’s official portal, most now offer this online rather than on paper

Common mistakes to avoid

• Assuming you don’t need to do anything just because tax is withheld automatically, missing a correction deadline means leaving a real deduction unclaimed
• Losing track of 3a contribution confirmations during the year, request them from your provider well before the deadline
• Not accounting for cantonal differences, the forms, deadlines, and portals are cantonal, not national
