How to complete a form for correction of tax withheld at source?

If you wish to request the correction of tax withheld at source, the corresponding form for the year in question must be submitted to the cantonal tax authority before 31st March of the following year.

There are two methods for submitting your form:

  • Complete the form online on your cantonal tax authority’s website
  • Complete a paper copy of the form received at the end of the year and return it by post to the cantonal tax authority

Once your form has been submitted, the cantonal tax authority will send you an acknowledgement of receipt and, if your file is complete and validated, calculate the amount of deductions to be refunded.

The deductions applicable to tax withheld at source can prove difficult to identify and calculate.
