The progression clause (Progressionsvorbehalt) in a side job affects students who receive parental allowance, sick pay, unemployment benefit or a similar benefit alongside their earnings. These benefits are not taxed themselves, but they can raise the tax rate on your wages. Many people only notice when the tax assessment arrives.
In short: Under the progression clause in section 32b EStG, wage-replacement benefits such as unemployment benefit, short-time work allowance, sick pay, maternity pay and parental allowance stay tax-free but are counted when setting the tax rate on your other income. If they exceed 410 euros together, filing a tax return is mandatory (section 46(2) no. 1 EStG). Last updated: November 2026.
Key points at a glance
- The benefits themselves are not taxed. They only raise the rate applied to your other taxable income.
- The list in section 32b(1) no. 1 EStG names, among others, unemployment benefit, short-time work allowance, sick pay, maternity pay and parental allowance. BAföG is not in this list.
- If the benefits exceed 410 euros a year, section 46(2) no. 1 EStG makes a tax return mandatory.
- Even if your wages alone are below the basic allowance (2026: 12,348 euros), the benefits can cause tax to arise on your wages.
- You only see the effect in the tax assessment. Payroll withholding in a side job usually does not know about the benefits.
What is the progression clause?
The progression clause is a calculation rule of income tax law. For certain tax-free benefits, the Income Tax Act provides that they are taken into account when the tax rate is determined. Under section 32b(2) EStG, taxable income is increased by the relevant income and benefits, and the resulting rate is applied to the income that is actually taxable (source: section 32b EStG, in German). The benefit stays tax-free, but the rate moves up.
The background is the progressive income tax scale, where the rate grows with income. Someone who receives a wage-replacement benefit alongside wages should not be better off than someone who earned the same money as wages.
Which benefits trigger the progression clause?
Section 32b(1) no. 1 EStG lists the benefits by letter. For students and career starters these matter most:
| Benefit | Place in section 32b(1) no. 1 EStG | Typical situation |
|---|---|---|
| Unemployment benefit, short-time work allowance | Letter a (SGB III) | After a job or working-student contract, during short-time work |
| Sick pay | Letter b (SGB V, VI, VII) | Longer illness alongside employment |
| Maternity pay and subsidies | Letters b and c | Maternity protection while employed |
| Parental allowance (Elterngeld) | Letter j | Parental leave, also with part-time work or a side job |
| Compensation for lost earnings under the Infection Protection Act | Letter e | Quarantine or ban on working |
BAföG is not named in this list. For the basics on parental allowance while studying see parental allowance during studies (in German), and for the planned reform parental allowance reform 2027.
How does it work in practice? An example without a euro tax figure
The calculation runs in four steps. You determine taxable income from wages and other income. Then you add the benefits. For this total the tax office determines the rate under the income tax scale. It applies that rate to the taxable income without the benefits.
Assumption: Your taxable income from the side job is 9,000 euros and you receive 6,000 euros of parental allowance in the same year. The basic allowance for 2026 is 12,348 euros (source: section 32a EStG, in German). Without the parental allowance your income would be below the basic allowance and no tax would arise. With it, the amount used to set the rate is 15,000 euros. That is above the basic allowance, so the special rate is greater than zero and is applied to the 9,000 euros. The tax in euros depends on further deductions and is shown reliably only in your tax assessment.
| Assumption | Without benefit | With parental allowance |
|---|---|---|
| Taxable income from side job | 9,000 euros | 9,000 euros |
| Benefit subject to progression clause | 0 euros | 6,000 euros |
| Amount used to set the rate | 9,000 euros, below the 2026 basic allowance of 12,348 euros | 15,000 euros, above the basic allowance |
| Effect | Rate of zero | Special rate above zero on the 9,000 euros |
Do I then have to file a tax return?
Yes, if the benefits exceed the threshold. Section 46(2) no. 1 EStG orders an assessment if the positive sum of income and benefits subject to the progression clause is more than 410 euros (source: section 46 EStG, in German). This applies even if your wages alone would not require a return. With several employers at the same time, no. 2 of the provision also applies if the wages were not combined for payroll withholding.
Deadlines and procedure are in tax return 2026: deadlines for students. How payroll withholding works in a side job is shown in working student and tax, and a comparison of job types in working student, mini-job or midi-job (in German).
How do you prepare for the tax assessment?
- Keep all notices and certificates for wage-replacement benefits received during the year.
- Plan for a possible back payment, since payroll withholding in a side job does not have to reflect the benefits.
- Check whether you have work-related expenses above the flat allowance that soften the effect.
- File the return on time even if you expect little tax.
Frequently asked questions
Do I pay tax on parental allowance?
No, the parental allowance itself stays tax-free. It is, however, subject to the progression clause under section 32b(1) no. 1 letter j EStG and therefore raises the rate on your other income.
Is BAföG affected by this clause?
BAföG does not appear in the list in section 32b(1) no. 1 EStG. The clause only applies to the benefits named there.
Why do I have to file a return although my wages are low?
Because not only wages count but also the sum of benefits subject to the progression clause. If it exceeds 410 euros, section 46(2) no. 1 EStG orders an assessment.
Can I avoid the progression clause?
It is provided by law and cannot be opted out of. You can only influence how high your taxable income is, for example by claiming work-related expenses.
What to do now
- List which wage-replacement benefits you received during the year and in what amount.
- Check whether the total exceeds 410 euros. If so, the tax return is mandatory.
- Collect payslips and proof of work-related expenses from the side job.
- Start the tax return and watch the filing deadline. Allow for a possible back payment.
