The canton of St. Gallen has a population of approximately 530,000, spread across 77 municipalities, some of which have significantly different tax rates. While Balgach, with a tax rate of 61%, is among the lowest-tax municipalities in Switzerland, taxpayers in the city of St. Gallen pay more than twice as much, with a tax rate of 138%. The cantonal tax law applies equally everywhere—but how much you actually pay in the end depends largely on your municipality and which deductions you claim.
The new eTax SG web application has been available in the canton of St. Gallen since the 2025 tax year. It allows individuals to file their tax returns electronically in a web browser without having to install any software. Users log in via the cantonal ePortal. eTax SG is an option for anyone who wishes to fill out their tax return on their own. However, if you want to ensure that all deductions are claimed correctly and in full, our tax advisors will handle the entire process for you. We work with all standard cantonal systems and are familiar with the specifics of St. Gallen’s tax forms.
In our practice, we see the same mistakes time and again in tax returns from the canton of St. Gallen: Commuters who drive to work forget to provide proof of necessity and forfeit the entire commuting expense deduction. Married couples fail to take full advantage of the maximum insurance premium deduction of CHF 6,800. Property owners report value-enhancing investments as maintenance expenses—or vice versa—and thereby forfeit potential deductions. And parents who could claim third-party childcare costs often don’t realize that, in the canton of St. Gallen, this is contingent on both parents being employed.
Our certified tax advisors are familiar with St. Gallen tax law and review each item individually. The result: You won’t pay more taxes than necessary, and you’ll save valuable time for the things that matter to you.

Foreign employees with a B or L residence permit, as well as cross-border commuters, are subject to withholding tax in the canton of St. Gallen. The withholding tax is deducted directly from their wages. Under certain conditions, however, it may be worthwhile to file a subsequent regular tax assessment (NOV), which allows for the withholding tax to be adjusted and additional deductions to be claimed.
Foreign employees without a C residence permit in the canton of St. Gallen are subject to withholding tax. This applies to individuals with a B residence permit (long-term residents), an L residence permit (short-term residents), and cross-border commuters who return to their home country daily.
In the canton of St. Gallen, the NOV is granted automatically for those with a gross annual income of CHF 120,000 or more. If your income is lower, you can apply for the NOV voluntarily. Deadline: by March 31 of the following year. The NOV allows you to claim additional deductions, such as Pillar 3a, professional expenses, or interest on debt.
We’ll determine whether filing a NOV is worthwhile for you, submit the application by the deadline, and prepare your complete tax return, including all deductions. Many people subject to withholding tax receive a refund through the NOV.
Property owners in the canton of St. Gallen must report the imputed rental value as income for tax purposes. This is generally set at 70% of the market rental value. In return, mortgage interest, maintenance costs, and administrative expenses can be deducted on the tax return. Those who do not occupy the entire property themselves can claim a 30% underutilization deduction in the canton of St. Gallen.
Since 2016, the canton of St. Gallen has had a hardship provision in place for AHV pensioners: If the imputed rental value represents a disproportionate financial burden, an application for a reduction may be filed. In addition, the so-called “preferential rent” rule was abolished in 2024, leading to changes in the rules for renting to related parties.
Additional fee: CHF 65 per property
