Children, separate households, maintenance payments — and plenty of cantonal differences. Switzerland shows significant variations between cantons when it comes to child support payments and child tax deductions. For separated or divorced parents, navigating these differences can be challenging.
Essential documents
When declaring maintenance payments for the first time, it's essential to include a copy of the divorce or separation decree, or a written separation agreement. This applies both when claiming deductions and when declaring received payments.
Practical tip: collect your receipts digitally — for example, using the Trust FIN Tax Portal on your mobile device. That keeps everything secure, structured, and ready when you need it.
Child tax deductions: cantonal differences at a glance
Each canton defines its own thresholds and conditions for child deductions, childcare deductions and education allowances. Check your cantonal tax guide to ensure you claim the correct amount — or run a quick estimate via our Swiss Tax Calculator.
Federal-level child deductions
In addition to cantonal allowances, the federal government provides uniform child deductions that apply across Switzerland. These are less complex and can be claimed in addition to cantonal deductions.
The importance of proper documentation
To benefit from these deductions, you must maintain complete and accurate documentation:
- Divorce or separation decree / agreement
- Proof of maintenance payments
- Receipts for childcare expenses
- Certificates of enrolment for children in training or education
Digital tip: digitise, store and securely share all relevant documents with your tax advisor. This helps you avoid errors, save time, and ensure full use of your tax benefits.
