Frequently asked questions

What is taxable income (zu versteuerndes Einkommen)?

It is your income after all deductions, allowances and lump sums. This tool starts from that figure and applies the tax tariff; it does not work out the deductions for you.

How does the splitting tariff work?

For jointly assessed spouses, the tax is twice the amount due on half the joint income. This usually lowers the tax when partners earn different amounts.

When is the solidarity surcharge due?

Since 2021 most people pay no soli. It only applies above a high income-tax threshold, with a phase-in zone, so it shows up only at higher incomes.

What is the difference between average and marginal rate?

The average rate is your total income tax divided by your taxable income. The marginal rate is the tax on the next euro you earn, which is higher because the tariff is progressive.

About this tool

This calculator applies Germany's official §32a EStG income-tax tariff for 2025 to your taxable income, with the basic allowance built in. It supports single and married (splitting) assessment and adds the solidarity surcharge and church tax where they apply.

It complements a gross-to-net salary calculator: where that one estimates monthly payroll deductions, this one works out the annual income tax from your taxable income. It is an estimate, not tax advice.
