Tax at Source Correction: Who Qualifies and What You Get

Foreign residents in Switzerland with B or C permits can claim professional expense deductions to correct overpaid taxes.

This scheme allows certain foreign residents to adjust their tax payments if their actual work-related costs are higher than the standard amount already accounted for.

Who it's for

This scheme is for foreigners living in Switzerland who hold either a B-permit or a C-permit. To qualify, you must be currently paying tax at source (locally referred to as Quellensteuer).

What you get

When you pay tax at source, a standard lump sum is typically applied to cover your professional expenses. However, if your actual work-related costs are higher than that standard amount, this scheme gives you the opportunity to deduct those extra expenses. By doing this, you can ensure your tax assessment reflects your true professional costs rather than just the standard estimate.

What it costs you

There is no direct fee mentioned to use this process, but it does require time and organization. You must gather your records and complete the filing by the deadline of March 31st of the following year.

The catch to know

The most important thing to remember is that this adjustment is not automatic. If you do not file a request for correction, you lose the chance to claim back any taxes you may have overpaid due to high professional expenses.

How to apply

  1. Gather all receipts and documentation related to your professional expenses.
  2. Contact your local Cantonal Tax Office to find out the specific way they require you to submit your claim.
  3. Complete the filing process to show that your expenses exceed the standard lump sum.
  4. Submit everything before the March 31st deadline.
