Thurgau Wealth Tax Calculator

Thurgau Wealth Tax Calculator 2025

Estimate your annual wealth tax liability in the Canton of Thurgau — adjust for filing status, basic allowance and municipal “Steuerfuss” multiplier.

The Canton of Thurgau levies a cantonal wealth tax on taxable net wealth (worldwide assets minus deductible debts) as at 31 December. The cantonal tax is calculated using a progressive base tariff in promille (‰). The resulting simple cantonal tax is then multiplied by the tax factors (“Steuerfüsse”) of the canton, municipality and church to determine your final wealth tax burden.

The calculator below uses a stylised approximation of Thurgau’s simple wealth tax tariff for the 2025 tax year and allows you to apply a user-defined municipal multiplier. It is designed for planning and comparison and does not replace the official calculator or tables of the Thurgau tax administration.

Simplified formula:
Step 1: Taxable Net Wealth = Net Wealth − Personal Allowance
Step 2: Simple Cantonal Wealth Tax = Apply progressive Thurgau tariff (in ‰) to Taxable Net Wealth
Step 3: Total Wealth Tax ≈ Simple Cantonal Tax × (1 + Municipal Multiplier)

For this planning tool, personal allowances are modelled as CHF 80,000 for single taxpayers and CHF 160,000 for married couples (joint assessment). Child supplements, church-tax variations and special reliefs are not fully captured; see Allowances & Deductions for more detail.

Interactive Calculator

Enter your net wealth, filing status and an approximate municipal multiplier for your commune. In Thurgau, typical combined tax levels (canton + commune + church) often correspond to around 1.1×–1.6× of the simple cantonal wealth tax, depending on municipality and church affiliation.

Example Scenarios

Example A — Single, CHF 1,000,000, Municipal Multiplier 0.45

Net wealth CHF 1,000,000.
Personal allowance (single) CHF 80,000 → taxable CHF 920,000.
Progressive simple cantonal wealth tax ≈ CHF 1,550 (rounded, using the stylised bands).
Municipal multiplier 0.45 → total wealth tax ≈ CHF 2,250 (145% of simple tax).
Effective burden ≈ 0.23% of net wealth.

Example B — Married, CHF 3,000,000, Municipal Multiplier 0.35

Net wealth CHF 3,000,000.
Personal allowance (married / joint) CHF 160,000 → taxable CHF 2,840,000.
Progressive simple cantonal wealth tax ≈ CHF 5,400 (rounded).
Municipal multiplier 0.35 → total wealth tax ≈ CHF 7,300 (135% of simple tax).
Effective burden ≈ 0.24% of net wealth (excluding detailed church tax and special deductions).

These scenarios are indicative and rounded. Actual assessments depend on the precise Thurgau wealth tax tariff, your municipality’s tax factor, church affiliation and full allowances and deductions as applied by the Thurgau tax authorities.
