    This guide provides an overview of who must file a tax return in Thurgau, how to do it, what forms you need, and how to submit your declaration on time using eFisc, the official software provided by the canton.

     

    The Swiss Tax Structure and Thurgau’s Role

     

    Switzerland has a three-level tax system: federal, cantonal, and municipal. While the federal income tax is standardized nationwide, cantons like Thurgau set their own income tax rates, deductions, and procedures. Your total tax burden in Thurgau depends on your municipality, income level, family situation, and other personal factors.

     

    Who Has to File a Tax Return in Thurgau?

    Not everyone is required to file a tax return in Switzerland. In Thurgau, the obligation depends on your residency status and income source. The following individuals generally must submit a tax declaration:

     

    Swiss Citizens and Residents

    All residents with income above the tax-free threshold must file annually.

     

    Foreign Nationals with a C-Permit

    Permanent residents (C-permit holders) are treated like Swiss citizens for tax purposes and must file a complete tax return.

     

    Foreign Nationals Without a C-Permit

    If you hold a B- or L-permit, your income is usually taxed at source (withholding tax). However, if your gross annual income exceeds CHF 120,000, or if you wish to claim deductions not included in the withholding tax, you must file a full tax return.

     

    Self-Employed Persons and Business Owners

    Freelancers, sole proprietors, and those running a business are required to declare their income, expenses, and assets through the regular tax filing process.

     

    Property Owners

     

    If you own property in Thurgau, you must declare the rental value, mortgage details, and related deductions, regardless of whether you live in the canton.

     

    Filing Process in Thurgau

    Thurgau offers two options for filing your tax return: on paper or using the eFisc software. eFisc is free to download and available for Windows and macOS users. It guides you step-by-step through the entire declaration.

     

    Step 1: Collect Your Documents

    Before starting, make sure you have:

    • Salary certificates (Lohnausweis)

    • Bank and investment statements

    • Pension contribution records (Pillar 2 and Pillar 3a)

    • Receipts for deductions (e.g., insurance, medical expenses, childcare)

    • Property-related documents and mortgage statements

    Step 2: Complete the Tax Return

    You can either:

    • Fill out the paper forms manually

    • Use the eFisc software for a guided digital experience

    The software helps prevent mistakes and automatically calculates totals. Once completed, you can submit the return electronically or print and mail it.

    Step 3: Submit by the Deadline

     

    The official tax return deadline in Thurgau is April 30 of the year following the tax period. If you need more time, you can request an extension by submitting a deadline extension form. This is available on the same official website.

     

    Withholding Tax (Quellensteuer) in Thurgau

    Foreign employees without a C-permit typically have taxes withheld directly from their salary by the employer. This is known as Quellensteuer, or withholding tax. While this system simplifies tax compliance, you still may need to file a full return if:

    • Your income exceeds CHF 120,000 per year

    • You want to claim deductions not included in the Quellensteuer

    • You have additional income or assets

    You can estimate your Quellensteuer amount using the official calculator:
