Switzerland has stay-based tax routes at 30 days with gainful employment or 90 days without gainful employment.

Who it applies to

People checking a connected Swiss stay, including whether they are gainfully employed.

The rule

Temporary interruptions do not necessarily end the relevant stay. Tax domicile can establish liability independently of these periods, and education or medical stays may have special treatment. Review the nature and continuity of your stay before using the reminder.

Counting the days

Counts elapsed calendar days from the selected stay start, including temporary interruptions. Record the end when this stay genuinely ends; the app does not decide whether an interruption ends residence.

Choose the date through which you want to count and enter the required permission or event dates.
Use the counting convention above. Overlapping recorded dates in the relevant region are counted only once.
Read the result alongside the conditions. Missing records and other eligibility requirements are not inferred from a total.

Exceptions & edge cases

Choose whether you are gainfully employed and set the start of the relevant stay. Temporary interruptions do not necessarily break it. Domicile can establish tax liability independently; study/medical exceptions may apply.

Common misconceptions

“A count below the day threshold settles tax residence.”

A recorded-day total is one component. Review the separate conditions and exceptions described on this page.

“Unrecorded days are included in the total.”

The calculator uses only the dates you enter. Missing history can make the result incomplete.
