For HR and payroll teams supporting a German workforce, the tax class system (Lohnsteuerklassen) is one of the most confusing parts of the payroll puzzle — and one employees ask about constantly. Tax classes don’t change an employee’s total annual tax bill, but they have a big impact on monthly net pay, which is why a wrong class turns into an unhappy first payday. This 2026 guide explains the six classes, the current rates and allowances, how tax class affects take-home pay, how it gets changed, the reform coming in 2030, and exactly where the employer’s responsibility begins and ends.
What are German tax classes?
Germany runs a wage-tax withholding system in which every employee is assigned to one of six tax classes (Steuerklassen I–VI). The class determines how much income tax (Lohnsteuer) your payroll must withhold from each monthly salary. It mainly reflects marital status and whether someone has a second job, and it decides how tax-free allowances are applied month to month. For 2026, the basic tax-free allowance (Grundfreibetrag) is €12,348 per person (€24,696 for jointly assessed married couples) — the first slice of income that is tax-exempt, applied automatically through the tax class.
German income tax rates in 2026
Tax classes sit on top of Germany’s progressive income tax. For 2026 the key reference points are:
- €0 – €12,348: tax-free (Grundfreibetrag).
- Above the allowance the rate rises progressively from 14%.
- The 42% top rate (Spitzensteuersatz) starts at €69,879 of taxable income.
- The 45% “wealth tax” rate (Reichensteuer) applies above €277,826.
On top of income tax, employees may pay the solidarity surcharge (now only for high earners) and, if they belong to a registered church, church tax of 8–9%. Social security contributions are separate again. The tax class doesn’t change these rates — it changes how much is withheld each month against them.
The six German tax classes
Here is what each class is for and how its allowance works:
| Tax class | Who it applies to | Basic allowance |
|---|---|---|
| Class I | Single, divorced, or widowed employees (and married employees whose spouse lives outside the EU) | Standard (€12,348) |
| Class II | Single parents (adds the Entlastungsbetrag single-parent relief) | Standard + single-parent relief |
| Class III | The higher-earning spouse in a marriage (paired with a Class V partner) | Double (approx. €24,696) |
| Class IV | Married couples with similar incomes (the default on marriage) | Standard, each partner |
| Class IV + factor | Married couples wanting a fairer monthly split | Standard each, adjusted by a factor |
| Class V | The lower-earning spouse (the counterpart to Class III) | None |
| Class VI | An employee’s second and any further jobs | None |
Class II adds relief for single parents; Class VI, used for a second employer, applies the highest withholding because the allowances are already used by the main job.
How tax class affects net pay
This is the point employees most often misunderstand. Your tax class does not change how much tax you owe for the year — that is settled by your annual tax return. What it changes is how much is withheld each month, and therefore your monthly take-home pay. For a married couple, the III/V combination shifts most of the allowance to the higher earner: the Class III spouse sees a high net pay, while the Class V spouse sees a much lower net and is often shocked by it, even though the household is optimised overall. A IV/IV couple each get their own allowance, so the split feels more even but may lead to a balancing payment or refund after filing. Because these are timing effects, the “right” class is about cash flow, not saving tax — a distinction worth setting out for every new hire.
Choosing and changing your tax class
Married couples can choose between three combinations: III/V (maximises the higher earner’s monthly net), IV/IV (even split, the default), or IV/IV with factor (Faktorverfahren), which distributes the tax burden accurately across the year and reduces surprise bills. A tax class change is triggered by life events — marriage, divorce, the birth of a child, or a spouse starting or losing a job. Crucially, only the employee can change their tax class, via the ELSTER online portal or their local tax office (Finanzamt); the employer cannot do it for them. The change then flows to payroll automatically through ELStAM (see below).
Coming change: tax classes III and V abolished from 2030
A significant reform is on the way. Under draft legislation (§38b EStG), Germany plans to abolish tax classes III and V from 1 January 2030 and move all affected married couples into Class IV with factor. The aim is a simpler, fairer monthly withholding in which each spouse benefits from income splitting directly in their pay, rather than one spouse carrying a punishing Class V deduction. It is not in force yet, but employers with German staff should be aware it is coming and expect employee questions as the date approaches.
German payroll, tax classes and ELStAM — handled
Applying the right Lohnsteuerklasse, retrieving ELStAM and getting monthly withholding exactly right is what a payroll partner is for. TopSource’s Germany payroll service (or our EOR) runs compliant German payroll end to end — so your team’s net pay is correct and you stay audit-ready, without a German tax specialist in-house.
Who is responsible: employer vs employee
One of the most common mistakes international HR teams make is trying to “fix” an employee’s tax class. Responsibilities split cleanly:
- The employer / payroll: retrieve each employee’s electronic wage-tax data (ELStAM) from the tax authority and apply exactly what it says. You implement the tax class — you do not choose or change it.
- The employee: the only person who can change their tax class, through ELSTER or the Finanzamt.
- The Finanzamt: maintains the ELStAM database. If its records are out of date (for example, it hasn’t registered a marriage), it keeps sending the old class, and payroll must apply it until corrected.
Common 2026 compliance pitfalls
A few things catch out employers each year. Allowances change: for 2026 the child allowance (Kinderfreibetrag) is €9,756 per child for jointly assessed parents, so payroll software and any EOR partner must be updated to the current figures. Mismatched child data — a tax class reflecting children an employee doesn’t have, or missing children they do — is a red flag in annual audits. And if you use an Employer of Record or payroll provider, make sure they give German employees net-pay simulations, so a hire can see how, say, moving from Class IV to Class III would change their monthly budget before it hits their payslip.
How a payroll partner handles tax classes for you
You don’t need to be a German tax expert to run a German team compliantly — but you do need the mechanics right every month. A specialist keeps you on the correct side of ELStAM, the current allowances and the 2030 transition. If you have a German entity, our Germany payroll service retrieves ELStAM, applies the right tax class and runs compliant monthly wage-tax withholding. If you employ in Germany without your own entity, an Employer of Record in Germany — the EOR model — becomes the legal employer and handles the whole payroll and tax-class process for you. Talk to our Germany team to get German payroll set up correctly.
