German tax basics
Tax Classes in Germany: Steuerklassen explained simply.
Your German tax class decides how much wage tax is deducted from your monthly salary. It does not usually decide your final annual tax bill — but it can strongly affect your monthly net salary, refunds, back payments and wage-replacement benefits.
Quick answer
Your tax class is mainly a payroll setting.
In Germany, employees pay wage tax every month through payroll. Your employer uses your electronic tax data, including your tax class, to calculate the wage tax deduction.
For many people, the most important point is this: the tax class changes monthly cash flow, but the final tax is usually calculated through the annual tax return based on your full situation.
Monthly net salary
The tax class can make your monthly net salary higher or lower.
Annual tax return
The annual tax return balances what was withheld with your final tax situation.
Couples should plan
Married couples can often choose between IV/IV, III/V and IV with factor.
Benefits can be affected
Some benefits are linked to net salary, so timing can matter.
The basics
What is a Steuerklasse?
A Steuerklasse is your German wage tax class. It is used by payroll to estimate how much wage tax should be withheld from your salary each month.
This is not the same as your final annual income tax calculation. Your final result depends on income, deductible expenses, family situation, church tax, health insurance, pension contributions and other personal factors.
The tax class decides how tax is collected during the year. Your tax return decides what the final tax should be.
Overview
The six German tax classes.
Tax Class I
Single or separated
Usually for single, divorced, permanently separated or widowed employees who do not qualify for another tax class.
Tax Class II
Single parent
For qualifying single parents who are entitled to the relief amount for single parents.
Tax Class III
Married, higher earner
Often used when one spouse earns much more and the other spouse is in tax class V. It can increase monthly net salary for the higher earner.
Tax Class IV
Married, similar income
The standard class for married couples or registered partners when both work and earn roughly similar amounts.
Tax Class V
Married, lower earner
Used together with tax class III. It usually creates higher deductions for the lower-earning spouse.
Tax Class VI
Second job
Usually applies to a second or additional employment relationship. It often has the highest monthly wage tax deduction.
For married couples
Which tax class combination should couples choose?
The right combination depends on income split, cash-flow preference, expected tax return and possible benefits such as parental allowance, unemployment benefits or sick pay.
Often suitable when both spouses earn similar salaries. Monthly deductions are more balanced.
Often chosen when incomes are very different. It can improve monthly cash flow for the higher earner, but may increase the chance of a tax back payment.
A more precise option for couples. The monthly wage tax is distributed more closely according to each spouse’s income share.
2026 note
What about the planned end of tax classes III and V?
Germany has discussed and planned changes to the III/V combination. The direction is to move couples toward tax class IV with factor in the future.
For readers, the practical message is: do not choose a tax class only because it creates the highest monthly net salary. Also check whether it may create a back payment later or affect wage-replacement benefits.
When to review your tax class
Common moments when your Steuerklasse matters.
Marriage
After marriage, couples should check whether IV/IV, III/V or IV with factor fits better.
Planning parental leave
Because some benefits use net salary, tax class timing can become relevant before a child is born.
Income changes
A salary increase, job loss or one spouse reducing hours can change the best setup.
Separation
Permanent separation usually requires a review of the tax class situation.
Practical steps
How to check or change your tax class.
Check your payslip. Your payslip usually shows your current tax class.
Compare scenarios. Use a German payroll or BMF calculator to estimate the monthly effect.
Apply through the tax office or ELSTER. Married couples usually apply together if they want to change the combination.
Review before major benefits. If parental allowance, unemployment benefits or sick pay may become relevant, get individual tax support early.
