Aargau Wealth Tax Calculator 2025

Estimate your annual wealth tax liability in the Canton of Aargau — adjust for municipal multiplier, filing status, and total net worth.

The following calculator models Aargau’s progressive cantonal wealth tax and applies a selected municipal multiplier to produce an indicative wealth tax result for the 2025 tax year. It is designed for planning and comparison purposes — not an official computation.

Aargau applies a progressive per-mille tariff (roughly 1.1‰–2.1‰) on taxable net wealth, with municipal multipliers frequently between 90–120 % of the cantonal base. Social allowances (around CHF 130,000 for single taxpayers and CHF 260,000 for jointly assessed married couples in 2025) are reflected in the model.

Formula (simplified): (Net Wealth − Allowance) × Cantonal Base Rate × (1 + Municipal Multiplier)
Municipal multiplier is entered as a factor on the cantonal base (e.g. 1.00 = 100 % municipal share → cantonal + municipal ≈ 200 % of simple tax).

Interactive Calculator

Enter your details below. The script uses an approximate Aargau progression and the 2025 personal allowances. For precise filing, always rely on the official Aargau tax tables or the cantonal calculator.

Example Scenarios

Example A — Single, CHF 1,000,000, Municipal Multiplier 0.80

Allowance ≈ CHF 130,000 → taxable ≈ CHF 870,000.
Indicative Aargau base rate ≈ 0.21 % → simple cantonal tax ≈ CHF 1,827.
Municipal multiplier 80 % (total factor 1 + 0.80 = 1.80) → total wealth tax ≈ CHF 3,300 (effective rate ≈ 0.33 % of net wealth).

Example B — Married, CHF 3,000,000, Municipal Multiplier 0.70

Allowance ≈ CHF 260,000 → taxable ≈ CHF 2,740,000.
Indicative base rate at higher band ≈ 0.21 % → simple cantonal tax ≈ CHF 5,754.
Municipal multiplier 70 % (total factor 1 + 0.70 = 1.70) → total wealth tax ≈ CHF 9,800 (effective rate ≈ 0.33 % of net wealth).

These scenarios are illustrative only. Aargau applies detailed stepped tariffs and social deductions that can shift the result, especially around allowance thresholds and specific family constellations.
