German Tax Classes Explained: Which Steuerklasse Applies to You?
Steuerklasse decides how much income tax comes out of your paycheck each month, not how much tax you owe for the year. Here's what each of the 6 classes means and how to tell which one is yours.

Quick answer
If you're single with no children, you're almost certainly Steuerklasse I. Single parents get II. Married couples are automatically placed in IV/IV unless they actively request III/V. A second job defaults to VI. Try it yourself in the salary calculator to see the exact effect on your net pay.

What is a Steuerklasse (tax class)?
A Steuerklasse is one of six categories the German tax office (Finanzamt) uses to estimate how much income tax (Lohnsteuer) your employer should withhold from your paycheck each month.
It's an estimate, not your final bill. Your actual annual tax liability is fixed by the progressive income tax formula (§32a EStG) applied to your real yearly income, family situation, and deductions, settled through your annual tax return (Steuererklärung). Steuerklasse only affects the size of the monthly installments you pay toward that bill in advance, and whether you end up owing more or getting a refund afterward.
For a single person, the choice is automatic and based on your registered family status. For a married couple, it's a genuine choice that affects monthly cash flow, though not the couple's combined annual tax.
The 6 German tax classes at a glance
Each class applies fixed allowances and a specific withholding formula. Here's what qualifies you for each one:
ISingle, divorced, or widowed
The default class for anyone who is unmarried, divorced, or widowed (in the year following the year of a spouse's death), with no children living with them, or married but permanently separated. Standard allowances apply: the basic tax-free allowance (Grundfreibetrag) and the standard employee lump sum (Arbeitnehmer-Pauschbetrag), nothing extra.
IISingle parents (Alleinerziehende)
For single parents who live alone with at least one child registered on their own tax card. Class II includes everything Class I does, plus the relief amount for single parents (Entlastungsbetrag für Alleinerziehende), an extra tax-free allowance that lowers monthly withholding. You need to actively apply for it through your Finanzamt; it isn't assigned automatically just because you're unmarried with a child.
IIIMarried, higher earner
One half of a married couple, almost always the higher earner, paired with a spouse in Class V. Withholding under Class III assumes a low- or non-earning spouse, so it applies double the basic allowance and results in the lowest monthly withholding of any class. It's also used for a widow or widower in the year their spouse died and the year after.
IVMarried, similar incomes (and IV with Faktor)
The automatic default the moment two people marry, unless they actively request III/V instead. Both spouses are taxed roughly as if they were single, each getting their own standard allowance. This fits best when both partners earn similar amounts.
IV with Faktor is a refinement of this: the Finanzamt calculates a multiplier (Faktor) based on both spouses' actual expected incomes so the combined monthly withholding lands closer to the couple's real annual tax bill, avoiding the large under- or over-withholding that III/V can produce when the income gap is smaller than expected.
VMarried, lower earner
The counterpart to Class III: the lower-earning spouse in the pair. Class V gets none of the basic allowance (it's all assigned to the Class III spouse instead), so withholding runs noticeably higher, correcting for how little Class III withholds on its own so the household's combined monthly payments roughly track its real combined tax liability.
VISecond job, or no ELStAM data on file
Applied to any job beyond your first, or to a job where your employer has no valid electronic wage tax deduction data (ELStAM) on file for you. No allowances apply at all here, so Class VI withholds the most of any class relative to that job's own pay. This doesn't change what you owe overall; a second income is taxed the same in your annual return regardless of which class withheld it during the year.
See the real difference: a worked example
Numbers, not just theory. Using this site's own tax engine for a single filer and a married couple in Bavaria, no church tax, statutory health insurance, tax year 2026, here's what four different Steuerklasse situations actually produce:
Notice the two combined couple figures aren't identical, they differ by about 48 €. That's not a bug in either class, it's the estimate-versus-actual gap Steuerklasse withholding always carries. III/V withholds less overall during the year, which is exactly why it can mean a larger back payment (Nachzahlung) once the annual tax return is filed. Either way, the couple's real annual tax bill, calculated jointly through Ehegattensplitting, is identical: the difference above is just when and how it gets settled.
Married couples: III/V, IV/IV, or IV with Faktor?
Here's the part that surprises a lot of people: whichever combination a married couple chooses, their total annual tax bill is identical. Steuerklasse only decides how that bill gets collected month to month, split between two paychecks instead of one combined figure.
III/V front-loads take-home pay toward the higher earner and away from the lower earner. IV/IV splits it more evenly between both. Neither is “cheaper” over a full year, though III/V can mean a larger tax refund (or a larger back-payment) at filing time if the actual income split doesn't match what the classes assumed. Compare both setups directly for your own numbers in the household calculator.
Worth knowing: a reform to eventually retire III/V in favor of a mandatory Faktorverfahren was drafted for 2030 as part of the Steuerfortentwicklungsgesetz, but that provision was dropped from the law before it passed in December 2024. III/V remains fully available with no abolition currently scheduled, though the idea could resurface in future legislation.
Both rows add up to the same combined tax. III/V just distributes it unevenly between the two paychecks; IV/IV splits it evenly.
How to check or change your Steuerklasse
Your current Steuerklasse is stored electronically as part of your ELStAM (Elektronische LohnSteuerAbzugsMerkmale) data, visible on any payslip and retrievable via ELSTER, the tax office's online portal.
- Marriage moves both partners to IV/IV automatically; switching to III/V (or IV with Faktor) needs an active request via the “Erklärung zum Steuerklassenwechsel bei Ehegatten” form at your Finanzamt.
- Divorce, the death of a spouse, or a child moving out can change which class applies; report the change to your Finanzamt rather than waiting for it to update itself.
- Married couples can change their combination as often as they like during the year, not just once. A 2020 reform (Drittes Bürokratieentlastungsgesetz) removed the old once-per-year limit. A change takes effect from the month after you apply; to have it count for the current calendar year, the Finanzamt needs your application by November 30.
Common mistakes worth avoiding
A few things people frequently get wrong:
- Assuming a lower monthly deduction means lower tax overall. III/V feels better on payday but doesn't reduce what a couple owes for the year, and can mean a larger back payment later.
- Forgetting to update Steuerklasse after a major life change. Marriage, divorce, or a spouse's death should be reported to the Finanzamt promptly, since ELStAM doesn't always update itself immediately.
- Confusing Steuerklasse with the number of Kinderfreibeträge. These are two separate fields on your ELStAM record. Children affect the Kinderfreibetrag count and eligibility for Class II, not the base class number itself for a couple.
- Assuming a new employer automatically knows your Steuerklasse. It's transmitted electronically via ELStAM using your Steuer-ID, but it's worth confirming on your first payslip that the right class was actually applied.

Frequently asked questions
What does a “Steuerklasse 4 Rechner” actually calculate?
A “Steuerklasse 4 Rechner” is simply a net-pay calculator run with tax class IV selected, the default for married couples with similar incomes. Our salary calculator supports all six classes, so you can see your take-home pay under IV and directly compare it against III, V, or any other class.
Can I choose my own Steuerklasse?
As a single person, no: your class (I or II) is determined automatically by your registered family status, not something you select. As part of a married couple, yes: you and your spouse can jointly choose between IV/IV, III/V, or IV with Faktor by filing the tax-class-change form with your Finanzamt.
What happens to my Steuerklasse if I get married or have a child?
Marriage automatically moves both spouses to IV/IV; you have to actively request III/V or IV with Faktor if you want it instead. Having a child doesn't change your Steuerklasse by itself, but it does affect other figures on your tax card (the Kinderfreibetrag count) and, if you become a single parent, makes you eligible to apply for Class II.
Does a higher Steuerklasse number mean I pay more tax overall?
No. Steuerklasse changes only how much is withheld from your paycheck each month, not your actual annual tax liability, which is calculated the same way regardless of class and settled through your tax return. It does matter for anything calculated off your net pay during the year, like parental or unemployment benefits, so the choice is still worth getting right even though the year-end total doesn't change.
