Germany, renowned for precision and exactness in all areas of life, also has a complex tax system. The tax classes in Germany are among those particularities that require a fundamental understanding, for example when exercising a profession, making investments, or for assessing the functioning of the economy of one of Europe’s most influential countries. This article provides an in-depth examination of the German tax classes and their impact on the financial circumstances of citizens.
Which tax classes exist in Germany?
In many countries, tax class simply refers to a specific percentage tax burden that a taxpayer pays. In Germany, however, the tax class not only determines the tax rate, but also governs other aspects of tax obligations.
The tax classes in Germany essentially relate to the personal situation of the taxpayer. Allocation is based on criteria such as marital status, presence of children, or type of employment relationship. Understanding one’s own tax class is essential for sound financial planning and to avoid unexpected tax implications.
Tax benefits are closely linked to tax classes – membership in a particular group determines the possibility to claim individual deductions. However, there is no universally best tax class; the relevant factor is always the respective individual situation. The system is designed to provide all persons earning income in Germany with the most favorable options possible.

Tax Class I – for single persons
The Tax Class I mainly applies to single taxpayers without children. This also includes divorced and widowed individuals, provided that the death of the spouse occurred at least one year previously – in the first year after a spouse’s death, Tax Class III applies.
For this category, the standard tax rate applies, with the taxpayer entitled to the basic tax allowance or standard income allowance. Furthermore, a simplified and expedited assessment procedure applies without the obligation to provide supporting documents for individual tax benefits – this can, in many cases, result in less favorable conditions.
It is a common question among employees in Germany whether submitting a tax return for Tax Class I is advisable. It is not always mandatory, though in some cases a significant tax refund can be achieved – the decisive factor here is the individual situation of the taxpayer.
Tax Class II – for single parents
In Tax Class II, single parents with at least one child who meet certain conditions may be classified. The conditions are met if the individual and the child live in a joint household and there is no spouse or registered partner present (if necessary, suitable proof must be provided).
The main feature of Tax Class II is the entitlement to claim an additional relief amount for children – this amounts to €4,260 for the first child in 2026, and for each additional child an increase of €240 per year applies.
When choosing the tax class in Germany, it is generally incorrect to rely solely on the decisions of friends or colleagues. Every case is different – decisive factors are marital status, children, number of employment relationships, and the income differential between spouses. Before making a decision, it is advisable to first assess which tax class actually corresponds to the individual circumstances and then evaluate whether a change could increase the monthly net income or reduce the risk of additional payments.
Tax Class III – for married persons with low income
In Germany, this tax class applies to married couples where income is earned solely by one partner, or the income of the second partner is significantly lower – in such cases, the combination of Tax Classes III and V is chosen. This leads to favorable tax rates and tax benefits for married couples, reducing the overall tax burden.
It should be noted that persons classified in Tax Class III are required to file a tax return annually with the German tax authority – there is an obligation to file (mandatory income tax return submission)
Tax Class IV – for married couples
Assignment occurs automatically upon marriage or entering into a registered civil partnership – provided both partners are employed and no joint application for a change to tax class III/V or IV with factor has been submitted. This variant is particularly advantageous for couples with similar income levels.
Tax Class IV with factor
Tax Class IV with factor is a solution for married couples and registered civil partnerships with relatively similar, but not identical, incomes – it combines the standard Tax Class IV with an individually calculated factor to allow more precise adjustment of payroll tax prepayments to the actual income situation (e.g., 60/40). Utilization of this method requires a joint application (application for payroll tax relief) submitted to the tax office or via employer. A certificate with an individual factor (factor certificate) will then be issued – in practice, one partner is assigned class IV with factor, the other remains in the standard class IV. This system ensures a fairer and more balanced collection of monthly payroll tax, thus reducing the risk of substantial additional payments or refunds in the annual income tax return. The factor is calculated on the basis of the anticipated gross annual income and may be updated during the year should income circumstances change.
Tax Class V
Tax Class V in Germany is primarily intended for married couples or registered civil partnerships in which one person has significantly lower income than the other. Typically, the partner with lower (or no) income is classified in Tax Class V, while the partner with higher income remains in Tax Class III.
In Tax Class V, the tax prepayments for the taxpayer are less favorable. The amount of prepayments is higher than in Class IV, but lower than in Class VI. For this reason, this tax class is predominantly chosen in marital partnerships where there are significant income differences between the partners.
Tax Class VI – for persons with secondary employment
Tax Class VI applies to taxpayers with more than one employment relationship. In the case of multiple sources of income, a separate calculation is made for each, where the highest tax rates are applied to one employment relationship. In Tax Class VI, tax prepayments are the highest; benefits are not considered within payroll – these can, however, be asserted via the annual tax return.
Is a change of tax class possible?
In most cases, a change in tax class is required if marital status changes – for example, upon marriage, divorce, commencement of separation, or death of a spouse. A change of tax class is also necessary when taking up secondary employment or in the event of significant changes in income. However, there are situations in which taxpayers have a choice regarding the tax class – in such cases, self-allocation to a particular class is possible, subject to certain formal requirements.
To change tax class in Germany, an application must be submitted to the tax office using a specific form. It should be noted that changes for married couples must always be made jointly.

For a change of tax class, the application for tax class change can be submitted directly online via the Elster platform. No proof is required for changing from tax classes III and V to IV and IV.
