Frequently asked questions

What is the one-fifth rule (Fünftelregelung)?

A severance is extraordinary income. Under §34 EStG the tax is five times the extra tax caused by adding one fifth of the severance to your income, which softens the progression and lowers the total tax.

Did anything change in 2025?

Yes. From 2025 employers no longer apply the rule in payroll, so more tax may be withheld up front. You claim the relief in your income tax return; the calculation itself is unchanged.

When does the rule help most?

It helps most when your other income is low relative to the severance, because the one-fifth slice is then taxed at a much lower rate. If you are already in the top bracket, the benefit is small.

Is this the exact tax I will pay?

It is an estimate based on the 2025 tariff and the income you enter. Your actual assessment depends on all your income and deductions, so treat it as guidance, not tax advice.

About this tool

This severance calculator applies the one-fifth rule (Fünftelregelung, §34 EStG) to estimate the income tax on a severance payment and compares it with taxing the whole amount normally, so you can see the saving.

It uses the 2025 income-tax tariff and your other taxable income to capture the progression effect. Since 2025 the relief is granted through the tax return rather than at payroll. It is an estimate, not tax advice.
