Solothurn Wealth Tax Calculator 2025

Estimate your annual wealth tax liability in the Canton of Solothurn — using the progressive wealth tax tariff, social allowances and a combined tax factor (Steuerfuss).

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

For the 2025 tax year, Solothurn’s simple wealth tax tariff (per year) is structured as follows:

  • 0.75 ‰ on the first CHF 50,000 of taxable wealth
  • 1.00 ‰ on the next CHF 50,000
  • 1.25 ‰ on the next CHF 50,000
  • 1.00 ‰ on the next CHF 850,000
  • 1.40 ‰ on the next CHF 1,000,000
  • 1.50 ‰ on the next CHF 1,000,000
  • 1.30 ‰ on taxable wealth above CHF 3,000,000

In addition, Solothurn grants social deductions on wealth: this tool models CHF 60,000 for single taxpayers and CHF 100,000 for married couples (joint assessment), in line with the typical social allowances used in practice. Child allowances (CHF 20,000 per child) and special reliefs are not fully modelled here.

Simplified formula:
Step 1: Taxable Net Wealth = Net Wealth − Social Allowance
Step 2: Simple Wealth Tax = Apply Solothurn progressive tariff (‰) to Taxable Net Wealth
Step 3: Total Wealth Tax ≈ Simple Wealth Tax × Total Tax Factor (Steuerfuss gesamt)

Interactive Calculator

Enter your net wealth, filing status and the combined total tax factor (Steuerfuss gesamt) applicable to your municipality (sum of canton, commune and church). As a rough indication, overall factors around 2.0–2.5× of the simple tax are common in Solothurn, but this varies by commune and church affiliation.

Example Scenarios

Example A — Single, CHF 1,000,000, Total Factor 2.30

Net wealth CHF 1,000,000.
Social allowance (single) CHF 60,000 → taxable CHF 940,000.
Applying the Solothurn wealth tax bands gives a simple wealth tax of roughly CHF 940.
Total tax factor 2.30 → estimated total wealth tax ≈ CHF 2,160.
Effective burden ≈ 0.22% of net wealth.

Example B — Married, CHF 3,000,000, Total Factor 2.30

Net wealth CHF 3,000,000.
Social allowance (married / joint) CHF 100,000 → taxable CHF 2,900,000.
Simple wealth tax (progressive tariff) ≈ CHF 3,750.
Total tax factor 2.30 → estimated total wealth tax ≈ CHF 8,625.
Effective burden ≈ 0.29% of net wealth (rounded; excludes child allowances and any church tax adjustments).

These scenarios are indicative and rounded. Actual assessments depend on your exact municipal and church tax factors, family situation, deductible debts and the Solothurn tax administration’s official calculations.
