Tax Returns in the Canton of Thurgau – What You Need to Know

80 municipalities, one tax law—but major differences

The canton of Thurgau is located on Lake Constance and has a population of approximately 290,000, spread across 80 municipalities. The deadline for filing tax returns is April 30—one month later than in most German-speaking cantons. The cantonal tax rate is 109%, while municipal tax rates range from 30% in Bottighofen to 72% in Hohentannen. Thurgau is known as an agricultural canton, but has increasingly become an attractive place to live for commuters to Zurich, Winterthur, and St. Gallen. Those who have their tax returns prepared by a professional benefit from the full and correct utilization of all Thurgau tax deductions.

eFisc – the new electronic tax return

In the canton of Thurgau, eFisc is a free desktop software program available to residents. It allows individuals to complete their tax returns on a computer and then submit them without having to install any software. eFisc is an option for anyone who wants to file their own tax return. 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 Thurgau’s tax forms.

Common Mistakes That Cost Thurgau Taxpayers Money

In our practice, we see the same mistakes time and again in tax returns from Thurgau: Commuters who travel daily to Zurich, Winterthur, or St. Gallen forget to take full advantage of the cantonal commuter deduction, which is capped at CHF 6,000, or fail to provide proof that using public transportation is reasonable. Farmers and part-time farmers—who are represented in Thurgau in greater-than-average numbers—incorrectly report income in kind and depreciation on farm buildings. Families overlook the child care deduction of up to CHF 10,100 per child per year. And property owners on Lake Constance are unaware that the canton of Thurgau does not offer an underutilization deduction or hardship provisions—which makes it all the more important to properly optimize effective property costs.

Good to Know

The canton of Thurgau offers a remarkable range of tax rates. Municipalities on Lake Constance, such as Bottighofen (30%) and Gottlieben, are among the most tax-friendly in Switzerland. In the hinterland, tax rates are higher, for example in Hohentannen (72%). For commuters to Zurich or Winterthur, the municipalities in western Thurgau are particularly attractive, as they combine low taxes with short commutes. Thurgau is increasingly positioning itself as an alternative to the more expensive cantons of Zurich and St. Gallen.

Numerous international professionals work in the Lake Constance region and in industrial areas. There are also cross-border commuters from Germany (Konstanz, Friedrichshafen).

In the canton of Thurgau, the NOV is granted automatically for gross annual incomes of CHF 120,000 or more. If your income is lower than that, you can apply for the NOV voluntarily.

Real Estate and Imputed Rental Value in the Canton of Thurgau

Property owners in the canton of Thurgau must report the imputed rental value as income. This is generally set at 70% of the market rental value.
