Geneva withholding-tax adjustment: points and deadline to check
Swiss withholding tax is calculated using the information available to the employer. A family change, partner income or certain deductions may justify checking the calculation and the suitable procedure.
Adjustment or subsequent ordinary taxation
In Geneva, the DRIS/TOU process can be used for a withholding-tax adjustment or subsequent ordinary taxation depending on the situation. A possible application is not automatically an advantageous one.
The deadline
The Geneva tax authority states that the request must generally be submitted by 31 March of the year following the withholding.
- Check the tax scale used
- List all household income
- Record dependent children and family changes
- Gather supporting documents
- Confirm the correct procedure before filing
