Tariff correction
CHF 220.-
This corrects the calculation of the tax withheld: tariff applied, annualised income, forgotten flat-rate deductions. The tax remains withheld at source. This is the simplest and lowest-risk process.

Withholding tax correction
Si votre salaire est imposé à la source, certaines déductions ne sont pas dans le barème. Une correction est possible, mais seulement jusqu’au 31 mars.
Deadline
31.03.2027
Statutory deadline, cannot be extended.
Two different processes, often confused
Subsequent ordinary assessment
CHF 390.-
You are taxed as an ordinary taxpayer, with a full tax return. You can deduct more, but all your income and wealth enter the calculation.
Two points we state before we start
- The subsequent ordinary assessment is not automatically advantageous: it can cost more than it saves. It deserves a comparative calculation, not a guess.
- The quasi-resident request is irreversible for the tax year concerned, and depending on your canton it also binds you for subsequent years. Once filed, there is no going back.
What is included, what is not
Included
