German Tax Classes (Steuerklassen): Which One Are You?

Two couples earning exactly the same money pay exactly the same income tax for the year — no matter which tax-class combination they pick. That surprises most newcomers, because a "better" Steuerklasse feels like it should save money. It doesn't. Your tax class decides how much your employer withholds from each payslip, not what you ultimately owe. It is a cash-flow lever, not a discount. Here is what all six classes mean, which one you are in, the married-couple decision that actually matters, and how to change class in 2026.

What a Steuerklasse actually does (and doesn't)

A tax class is an instruction to your employer about how much Lohnsteuer — monthly wage-tax — to hold back from your gross salary. It works by assuming which allowances apply to you, above all the Grundfreibetrag: the slice of income that is tax-free. For 2026 the Grundfreibetrag is €12,348 per person, and it doubles to €24,696 for jointly-assessed married couples (Bundesfinanzministerium).

What the class does not do is change your final Einkommensteuer. That number is fixed by your annual tax return, which reconciles everything your employer withheld against what you actually owed. So a class that withholds less simply means more cash in-year and a smaller refund — or a bill — at reconciliation.

The six classes, in one table

Germany has six classes, and for most people the class is assigned automatically — at your Anmeldung, on marriage, or when you take a second job. This table maps the common life situation to its class and the 2026 figures that come with it.

Class	Who it applies to	Key 2026 detail
I	Single, divorced, or widowed (from the 2nd year after bereavement)	Full personal Grundfreibetrag €12,348
II	Single parents living alone with a child and claiming Kindergeld	Adds Entlastungsbetrag €4,260 (1st child) + €240 each further
III	Higher-earning spouse in a married couple (paired with V)	Absorbs both allowances (€24,696) — lowest withholding
IV	Each married partner, taxed independently (the default)	Like class I for each partner
V	Lower-earning spouse paired with III	No allowance at source — highest withholding
VI	Second and further jobs	No allowances; taxed from the first euro

When I married, both of us were put on IV/IV automatically — nobody at the Finanzamt asks which combination you want. Changing it is a deliberate step you have to take yourself, which is why so many couples stay on a default that may not suit their income split.

Married couples: III/V vs IV/IV vs IV with Faktor

This is the only Steuerklasse decision with real money attached, and it comes down to timing and risk, not the size of the annual tax bill. Here is how the three combinations compare.

Combination	Fits	Monthly cash	Year-end reconciliation
III/V	Large income gap (roughly 60/40 or wider)	Highest household cash now	Mandatory joint return; back-payment likely
IV/IV	Similar incomes; the automatic default	Moderate; each taxed like a single	Refund likely if incomes differ
IV + Faktor	Any couple wanting accuracy	Splitting benefit spread evenly	Mandatory return; smallest surprise

Under III/V, the class-III partner's payslip looks generous because it carries both tax-free allowances, while the class-V partner is withheld heavily. The household sees more combined cash during the year — but the class-III payslip flatters the couple's real position, so the joint return usually claws money back. An illustrative couple on roughly €78,000 combined at a 70/30 split can face a €500–€2,000+ back-payment. That is not a penalty; it is the year-end truth arriving all at once.

IV with Faktor fixes the timing problem. The tax office calculates a personal factor so each partner's monthly withholding already reflects the couple's real joint liability — you keep the splitting advantage of marriage, but spread evenly, with minimal year-end swing (Finanztip).

How to change your tax class in 2026

Switching class is simpler than it used to be, and you have more freedom than older guides suggest.

1. You can change as often as you need. The old once-per-year limit was scrapped in 2020 — married couples may now switch class combination multiple times in a single year.
2. It's digital-only now. Since 2024 the change runs exclusively through the ELSTER portal; the paper Finanzamt form has been discontinued. Log in and file the Antrag auf Lohnsteuer-Ermäßigung with the Anlage Steuerklassenwechsel for couples (ELSTER).
3. Mind the 30 November deadline. An application received by 30 November takes effect for the current year, from the following month. File later and the new class applies from January of the next year.
4. Life events open the door. Marriage, the birth of a child, or a separation each trigger or permit a specific change — the class does not update itself.

Common mistakes and edge cases

The pattern behind most Steuerklasse regret is treating a timing lever as a tax cut.

• Assuming class III "saves tax." It doesn't — the annual bill is identical; it only shifts cash forward.
• Forgetting the mandatory joint return after choosing III/V, then being caught out by the back-payment.
• Panicking at class V withholding. It looks brutal on the payslip but is reconciled at year-end; it is the counterpart to the class-III partner's light withholding.
• A second job silently on class VI, taxed from the first euro with no allowance.
• Single parents not claiming class II, and losing the €4,260 Entlastungsbetrag they're entitled to.

Getting the timing right is worth more than chasing a "best" class. The same annual-review habit that stops your energy bills drifting expensive applies to your tax class: set it deliberately, then revisit it when your income or family situation changes.

Frequently asked questions

Which tax class am I in Germany?

If you're single, you're in class I; it's assigned automatically at your Anmeldung. On marriage, both partners are placed in IV/IV by default unless you actively switch. Single parents who qualify can move to class II, and any second job is taxed under class VI. You can see your current class on your payslip (Lohnsteuerklasse) or in your ELSTER account.

Is tax class 3 or 4 better when married?

Neither is "better" for your annual tax — that total is the same. It's a timing choice. III/V (with the higher earner on III) maximises monthly household cash but usually leads to a year-end back-payment, and it fits couples with a large income gap. IV/IV or IV with Faktor keeps monthly withholding closer to the real liability, so there are fewer surprises. Couples with similar incomes commonly stay on IV+Faktor.

How do I change my tax class in Germany?

Since 2024 the change is digital-only through the ELSTER portal — the paper form is gone. File the Antrag auf Lohnsteuer-Ermäßigung with the Steuerklassenwechsel annex. Since 2020 you can change as often as you like per year. An application received by 30 November takes effect for the current year; later applications apply from January the following year.

Does changing tax class save money?

Not on your annual income tax — that's fixed by your tax return regardless of class. Changing class only shifts cash between your monthly payslip and your year-end settlement. The one real exception is wage-replacement benefits (Elterngeld, Arbeitslosengeld, Krankengeld), which are based on net pay, so the class you're on beforehand can change what you actually receive.

Are tax classes 3 and 5 being abolished?

A reform to move all couples to IV with Faktor was previously planned for 2030, but it was not enacted after the governing coalition collapsed, and no firm date exists as of 2026. For now, III/V remains fully available. If the reform is eventually passed, the splitting advantage itself wouldn't disappear — it would simply be delivered through the Faktor method instead.
