Determination of electronic income tax deduction items (ELStAM), change of tax class for spouses/civil partners (not permanently separated)

Employees are assigned tax classes for the purpose of income tax deduction. Spouses or partners who live in Germany, are not permanently separated and both earn an income can choose tax class combinations III/V or the so-called factor procedure (IV/IV with factor) instead of tax class combination IV/IV. The income tax withheld during the calendar year does not determine the total amount of the applicable (annual) income tax. The total (annual) income tax is also not influenced by the tax class choice of spouses or civil partners.

The standard tax class combination IV/IV is generally more favorable if both spouses or civil partners roughly earn the same income. The tax class combination III/V is recommended if one spouse or partner earns approximately 60 percent or more of the joint income and is classified in tax class III.

If you apply for tax class combinations III/V or IV/IV with a factor, you will be required to file an income tax return.

  • If you submit the application in person, it will usually be processed immediately.
  • Your employer will be notified of the amended ELStAM and their validity via the electronic retrieval procedure. If you wish to receive a printout of your ELStAM, please indicate this on the application form. You can also check your own ELStAM after registering free of charge at "ELSTER: Ihr Online-Finanzamt" (
