If you've just started working in Germany and noticed a cryptic Roman numeral on your payslip (I, III, V, etc.), that's your Steuerklasse, the tax class your employer uses to calculate how much wage tax (Lohnsteuer) gets withheld from each paycheck. Picking the right one, or switching when your life changes, can mean hundreds of euros a month in your bank account.
*Last updated: May 23, 2026*
## What Steuerklassen Actually Do
Germany has six tax classes (Steuerklassen I through VI). They do not change how much income tax you ultimately owe for the year, that is calculated when you file your annual return. What they change is how much your employer withholds each month under § 38b of the Einkommensteuergesetz (EStG).
Think of the class as a withholding profile. It tells the payroll system which allowances to bake into the monthly calculation: the basic tax-free allowance (Grundfreibetrag), the single-parent relief (Entlastungsbetrag für Alleinerziehende), child allowances, and so on. The annual tax return then squares everything up, and you either receive a refund or owe a balance.
For 2026, the key reference numbers that feed into every class are:
- Grundfreibetrag (single): €12,348
- Grundfreibetrag (jointly assessed couples): €24,696
- Top rate (42%) starts at: €69,879 of taxable income
- Reichensteuer rate (45%) applies above €69,879
- Solidaritätszuschlag (up to 5.5%): only on income tax of €20,350+ (single) or €40,700+ (couples)
- Kinderfreibetrag: €9,756 per child
- Kindergeld: €259 per child per month
## The Six Classes at a Glance
| Class | Who it's for | Basic allowance applied? |
|---|---|---|
| I | Single, divorced, separated, widowed (from year 2 after bereavement) | Yes |
| II | Single parents meeting the Entlastungsbetrag criteria | Yes + €4,260 single-parent relief |
| III | Higher-earning spouse in a marriage (partner in Class V) | Doubled (both spouses' allowances) |
| IV | Default for married couples with similar incomes | Yes (each spouse) |
| IV with Factor | Married couples wanting proportional withholding | Yes, adjusted by Faktor |
| V | Lower-earning spouse when partner uses Class III | None at withholding stage |
| VI | Any second or additional job (not Minijobs) | None, taxed from euro one |
### Steuerklasse I
The default for most foreigners arriving in Germany alone. If you are unmarried, divorced, separated, or your spouse lives outside Germany, you land here. The full Grundfreibetrag of €12,348 is built into your monthly withholding.
### Steuerklasse II
Reserved for single parents who meet strict criteria set by the Finanzamt: you must live alone with the child (no other adult in the household, with narrow exceptions), and you must receive Kindergeld or claim the Kinderfreibetrag for that child. The reward is the Entlastungsbetrag für Alleinerziehende: €4,260 per year for the first child, plus €240 for each additional child. You have to apply for this class actively, it is not assigned automatically.
### Steuerklasse III and V
This is the combination most international couples ask about. One spouse takes Class III, the other Class V. The Class III partner absorbs both basic tax-free allowances (€24,696 total), so their monthly net is unusually high. The Class V partner gets no basic allowance at the withholding stage, so their monthly net looks painfully low.
Two hard rules to know:
- Both spouses must be registered residents in Germany. If your partner still lives abroad, you cannot use III/V. The employed spouse stays in Class I.
- Couples in III/V are legally required to file a joint annual return (Pflichtveranlagung). You cannot skip the Steuererklärung.
III/V works best when one spouse earns roughly 60% or more of the household income. If incomes are similar, it usually means a large back-payment after the annual return.
Note: a previously discussed plan to abolish Classes III and V from January 1, 2030 (moving everyone to IV with Factor) was never enacted into law after the previous coalition collapsed. The Ehegattensplitting method itself remains untouched. As of 2026, III/V is still fully available.
### Steuerklasse IV and IV with Factor
The automatic class assigned to both spouses the moment your marriage is registered with the Standesamt. Each spouse gets their own Grundfreibetrag at withholding. This is the fair-and-simple option when both partners earn roughly the same.
IV with Factor (Faktorverfahren) is the smarter cousin: the Finanzamt calculates a factor based on your projected joint income and applies it to both salaries. Monthly withholding ends up much closer to your actual annual liability, which avoids the III/V cliff. Couples who use it are also subject to mandatory joint filing.
### Steuerklasse VI
This is the class nobody wants. It applies to any second or additional employment (Minijobs under €556/month are excluded). No allowances apply, and withholding starts from the very first euro at the highest marginal rate.
Class VI is also where new employees end up by accident: if you fail to give your employer your 11-digit Steuer-Identifikationsnummer in your first month of work, payroll defaults to Class VI until you fix it. You will get the over-withheld amount back via your annual return, but in the meantime your net is brutal.
## Which Class Will I Be Placed In?
When you register your address (Anmeldung) and receive your Steuer-ID by post a few weeks later, the Finanzamt assigns a class automatically based on your civil status:
- Single, no children registered in Germany: Class I
- Married, both partners resident in Germany: both placed in Class IV by default
- Married, partner lives abroad: Class I
- Single parent meeting criteria: Class I initially, then apply for Class II
- Second job: Class VI (assigned by employer)
You cannot pick your class at registration. Changes happen only by application after the fact.
## How to Change Your Steuerklasse
Married couples and registered partners can switch between IV/IV, III/V, V/III, and IV/IV with Factor as often as needed throughout the year. The mechanism:
1. Both spouses fill out and sign the form *Antrag auf Steuerklassenwechsel bei Ehegatten/Lebenspartnern*.
2. Submit to the Finanzamt that handles your address, either on paper or electronically via ELSTER (Form ID 034008, Anlage Steuerklassenwechsel) at elster.de.
3. The Finanzamt updates the ELStAM (Elektronische LohnSteuerAbzugsMerkmale) database, and the change is pushed automatically to your employer's payroll system.
4. Under § 38b EStG, the new class takes effect from the month following approval. Processing usually takes two to four weeks.
There is no fee for a tax class change.
If you are a freelancer or self-employed and don't receive a wage, Steuerklassen do not apply to you in the same way. Your income tax is calculated and paid quarterly based on Finanzamt assessments.

## Documents Checklist
For most class changes or initial registrations, prepare:
- 11-digit Steuer-Identifikationsnummer (both spouses for joint applications)
- Anmeldebescheinigung (proof of registered address)
- Marriage certificate (translated and apostilled if issued abroad) for first-time marriage-related changes
- Birth certificates of children, for Class II or child allowance updates
- Passport or Aufenthaltstitel (residence permit)
- The completed and signed Antrag form
For single-parent Class II applications, you will also be asked to confirm in writing that no other adult shares your household.
## Fees, Deadlines, and Processing Time
| Item | Detail |
|---|---|
| Cost of a Steuerklassenwechsel | €0 |
| Processing time (Finanzamt) | 2 to 4 weeks |
| Effective from | Month following approval |
| Number of changes per year | Unlimited |
| Tax return deadline (self-filed, 2025 tax year) | July 31, 2026 |
| Tax return deadline (with Steuerberater, 2025 tax year) | February 28, 2027 |
| Joint filing required for | III/V and IV with Factor couples |
The 2026 Pendlerpauschale (commuting allowance) is also worth noting at filing time: it was unified at 38 cents per kilometer from the very first kilometer effective January 1, 2026, where previously this higher rate only applied from kilometer 21 onwards.
## Common Pitfalls Foreigners Run Into
Defaulting to Class VI on a new job. Always hand over your Steuer-ID to HR before the first payroll run. If you don't have it yet because your Anmeldung is fresh, tell HR in writing so they don't process you at the punitive Class VI rate.
Choosing III/V when incomes are close. If you earn within roughly 40/60 of each other, III/V usually creates a large tax bill at year end. IV with Factor is almost always the better choice for similar earners.
Forgetting that III/V requires a joint return. Couples who pick III/V cannot opt out of the annual Steuererklärung. The Finanzamt will eventually send a reminder, and late filing brings penalties.
Spouse abroad, applying for III/V. This does not work. Both partners must be German tax residents. If your partner is still finishing up in your home country, you stay in Class I until they register here.
Single parents missing Class II. Many foreign single parents never realize they need to apply. The €4,260 relief is sizeable. If a new partner moves in with you, you must report it because Class II is no longer valid.
Confusing tax class with tax owed. Switching to Class III does not lower your annual tax bill, it just shifts the timing. Your real liability is settled at year end.
Health insurance overlap. Your Steuerklasse interacts with your social security contributions. The 2026 statutory health insurance contribution ceiling is €69,750 per year, and the threshold to switch to private insurance is €77,400 per year.

## FAQs
Do I have to actively choose a Steuerklasse when I arrive?
No. The Finanzamt assigns one automatically based on your civil status once you complete your Anmeldung. You only act if you want to change it.
Can two foreigners married outside Germany use III/V?
Yes, as long as both spouses are registered residents in Germany and the marriage is legally recognized. You will likely need a translated and apostilled marriage certificate when you first notify the Finanzamt.
How often can married couples switch tax classes?
As often as you want during the year. The change applies from the month after Finanzamt approval.
My employer says I'm in Class VI but I only have one job. What happened?
Almost always: your Steuer-ID didn't reach payroll on time. Give HR the 11-digit number now. They will pull the correct class from ELStAM, and any over-withheld tax comes back via your annual return.
Do Minijobs get a Steuerklasse?
No. Minijobs (up to €556/month in 2026) are taxed at a flat rate by the employer and do not trigger Class VI for your main job.
Does choosing III/V cost me money long-term?
Not if you file your annual return correctly. The total tax owed for the year is the same regardless of monthly class. III/V just front-loads more take-home pay to the higher earner.
What if I separate from my spouse?
You must inform the Finanzamt. From the calendar year after permanent separation, both partners revert to Class I (or Class II if single-parent criteria are met).
Where do I check my current class?
On your monthly Lohnabrechnung (payslip), usually labelled "StKl" or "Steuerklasse." You can also view your ELStAM record by logging into elster.de.
## A Practical Move-In Order
If you have just landed in Germany, the cleanest sequence is:
1. Complete Anmeldung at your local Bürgeramt.
2. Wait for your Steuer-ID to arrive by post (two to six weeks).
3. Hand the Steuer-ID to your employer's HR immediately.
4. Sort out [opening a bank account in Germany](https://migaku.com/blog/language-fun/best-banks-in-germany-for-foreigners-n26-deutsche-bank-sparkasse-ing) so your net salary lands somewhere.
5. If married, decide between IV/IV, IV with Factor, or III/V and submit the Steuerklassenwechsel form.
6. File your first Steuererklärung the following spring via ELSTER.
Most of the German bureaucratic correspondence you will receive about your Steuerklasse, from the Finanzamt assignment letter to the ELStAM confirmation, arrives in German only. Being able to read official letters confidently saves a lot of stress. If you're settling into life in Germany, building everyday German with real native content makes navigating tax letters, doctor visits, and Mietverträge much less painful. Migaku is built for exactly that.
