Ah taxes… Don’t we just all love it?

Probably one of the most boring topics to deal with but also one of the most essential ones, especially in Germany. There are many factors impacting on your income tax rate; few of them are more important than your tax class.

In this post, we will go over what it all means and if you think it’s relevant to your situation, how to change your tax class in Germany.

How to change tax class in Germany

Tax classes in Germany: TL;DR

In nutshell; your tax class in Germany is more or less defined by your marital status. Depending on this, you will be put in different categories by the Finanzamt. This will help your employer apply the correct tax rate on your payslip, hence the name “Lohnsteuerklasse”. This impacts how much wage tax (“Lohnsteuerabzug”), solidarity contribution (“Solidaritätszuschlag”) and Church tax (“Kirchensteuer”) will be taken from your gross salary.

In other words, your net salary is directly related to your tax class in Germany.

As you might have already guessed it; this is only relevant to employees. Self-employed are paying income tax through other means.

Quick overview

There are 7 categories overall.

Tax classMarital status
Steuerklasse 0You are not a German resident.
Steuerklasse 1You are single, widow(er), separated/divorced
Steuerklasse 2You are a single parent
Steuerklasse 3You are married with a higher income (than your partner in Steuerklasse 5)
Steuerklasse 4You are married with both equivalent income
Steuerklasse 5You are married with a lower income (than your partner in Steuerklasse 3)
Steuerklasse 6The class used for additional jobs (Nebenjob or Zweitjob)

Attention married people: you can save money

As you can see, married people can belong to different classes and optimize differently. By default, the Finanzamt will put both partners in tax class 4, when you first register your marriage or marry in Germany. However, for a lot of households, this is often not the best solution. Why, you ask?

It’s quite simple really: the German tax system knows that the higher-earner is often bearing more of the costs in the household. The idea here is to allow for a tax rebate when one of the partners earns significantly less than the other. As a result, moving from tax class 4 to tax class 3/5 might increase the net salary for the higher earner.

When is it worth to change classes in that case?

The higher-earner in the household has to earn a good deal more for this to make sense. They should earn at least 60% of the total household income.

The process to change tax class in Germany is fairly simple:

  1. Login with your Elster account and head to this form.
  2. Select the year for which this should take place (you can select the current year if application is sent before the last day of November)
  3. First page is your personal details.
  4. Second page is your partner’s details.

Important notes

  • The tax class change will happen on the month following the request submission. So that’s when you can see a difference in your net salary.
  • If both partners are employees and you have been through a tax class change in Germany, it is mandatory to submit a tax declaration (Steuererklärung; more info this way) after the end of the year (e.g: do one in 2022 for the year 2021, if you changed in 2021)
You or your Steuerberater will appreciate the change !

Tax class switch Germany – FAQ

Can the tax benefit apply retroactively if I change tax classes late in the year?

Provided you make the application before 30/11 of that year, you can benefit from that tax cut for the months prior too.

How many times a year can I change tax classes in Germany ?

In most cases, this is only possible once a year. However, it is possible to do this more often in the following cases:
• When your partner is not an employee anymore (becoming a freelancer, retirement, parental leave, unemployment).
• When your partner is an employee again.
• When one of the partners passes away.
• In case of divorce or separation.

Which events can be cause of a tax class change?

Very logically, life events that were just previously listed can be cause for change of tax class in Germany; marriage, divorce, death of partner, unemployment, retirement, parental leave, becoming a freelancer.

I just got divorced/separated, what do I do now to change class?

You would use this form (Erklärung zum dauernden Getrenntleben) to signify the Finanzamt that you are now separated from your partner. The adjustment will be then made automatically after they process this document. You can also do this via Elster here.

My partner is living abroad, can I still change tax class?

For a tax class change to be possible, both partners need to be “unbeschränkt einkommensteuerpflichtig“, which means to be subject to an unrestricted income taxation. In practical terms, this is made possible only when the partner is also a German resident. However, an exception to this rule is possible if you and your partner fulfill the following requirements (source):

• You have EU or Swiss citizenship.
• Your partner has residence in another EU country (+ Switzerland).
• At least 90% of the total income is subject to German income tax. The same applies if the income not subject to German income tax does not exceed 18 336€ in a calendar year.
