Taxable income is a central concept that forms the basis for calculating income tax. It comprises the income of an individual or company after deduction of all allowable expenses, allowances and lump sums. This value is decisive for determining the tax burden and reflects financial performance. Understanding and correctly applying this concept is essential for effective tax planning and optimization in the context of business administration.
Taxable income (zu versteuerndes Einkommen, zvE) is the assessment base for German income tax: the sum of all income categories minus deductible expenses, special expenses, extraordinary burdens, and allowances. It is significantly lower than gross income – only what remains after all deductions is actually taxed.
"Taxable income" is a term used in tax law and refers to the amount of income to which the tax rate is applied in order to calculate income tax. It results from the income of a taxpayer after deduction of certain amounts and allowances.
These are the steps that usually lead to the determination of taxable income:
The taxable income is therefore the amount that remains after all the permitted deductions and allowances have been taken into account and to which the respective tax rate is applied to determine the amount of income tax. The tax rate is progressive, which means that the tax rate increases as the taxable income increases. [1]
Taxation of taxable income in Germany (and in many other countries) follows the principle of ability to pay. This principle states that people should be taxed according to their economic performance. This means that those who earn more and therefore have a higher economic capacity should also make a higher contribution in the form of taxes. The calculation of taxable income serves to determine this capacity as fairly and accurately as possible.
The purpose of taxing taxable income is to distribute the tax burden according to individual financial ability while supporting political, social and economic goals. Here are some reasons why only taxable income is taxed:
| Aspect/category | Explanation and objective |
| Consideration of personal circumstances | By deducting certain expenses and personal circumstances (such as special expenses, extraordinary burdens, allowances for children) from gross income, the tax base is adjusted to individual financial capacity. This takes into account social and economic differences between taxpayers. |
| Progressive tax system | Determining taxable income allows for the application of a progressive tax system, which imposes a higher tax rate on higher incomes. This promotes social justice by ensuring that the tax burden is distributed according to economic capacity. |
| Promotion of certain policies | The option of deducting certain expenses from gross income can be used to promote specific economic or social goals. For example, tax breaks for investments in sustainable technologies or for retirement provisions can help to steer investment in these areas. |
| Avoiding double taxation | Specific deductions and allowances can prevent income from being taxed multiple times. This applies, for example, to income that has already been taxed in another country or for which capital gains tax has already been paid. |
| Simplicity and administrative burden | Although the income tax calculation system may seem complex, it aims to enable fair and efficient taxation. The focus on taxable income allows for a standardized calculation method that takes into account a wide range of personal circumstances. |
Taxable income can be found in the annual income tax return submitted to the tax office. Once all relevant information has been entered in the tax return, the taxable income is determined by the tax office or by tax calculation programs.
In order to determine your taxable income, it is therefore necessary to fill out your tax return carefully and completely and to include all relevant receipts and supporting documents. Tax software or advice from a tax advisor can help you avoid mistakes and ensure that you take advantage of all tax benefits. Here are the steps to follow to find out:
In Germany, income is divided into seven categories for tax purposes. This classification is relevant for calculating taxable income and, consequently, for determining income tax.
Only income that falls under one of these seven categories is subject to taxation. Tap a card:
This category covers income from the systematic use of land for the production of plant or animal goods. Taxable income equals revenues minus operating expenses.
Example: A farmer runs a holding with grain crops and dairy cattle. Income includes proceeds from selling milk and grain, as well as subsidies received for agricultural activities.
Further examples: wineries, tree nurseries, beekeeping, forestry operations
Profits from an independent, ongoing activity with a profit motive in trade, crafts, industry, or another commercial sector – with participation in economic commerce. Subject to trade tax (Gewerbesteuer) in addition to income tax.
Example: A self-employed carpenter earns income from selling furniture and providing services, minus operating expenses such as material costs, workshop rent, and staff salaries.
Further examples: retail businesses, online shops, restaurants, manufacturing companies
Profits from freelance work – scientific, artistic, literary, educational, or one of the catalogue professions listed in § 18 EStG. Unlike business income, no trade tax (Gewerbesteuer) applies.
Example: A freelance architect earns fees for planning services, minus profession-related expenses such as office rent, software licences, and travel costs.
Further examples: doctors, lawyers, tax advisors, freelance journalists, consultants
Income from an employment relationship where the employer withholds wage tax (Lohnsteuer) directly. Deductible: employment-related expenses (Werbungskosten), at minimum the standard employee allowance of €1,230.
Example: A teacher at a public school receives her monthly salary, reduced by wage tax and social security contributions withheld by the employer.
Further examples: salary, wages, Christmas bonus, non-cash benefits such as a company car
Income from interest, dividends, and other capital returns. These are generally subject to the flat-rate withholding tax (Abgeltungsteuer) of 25 % and therefore do not appear in the taxable income base – unless the more favourable individual rate check (Günstigerprüfung) applies.
Example: An investor holds shares in a company that pays an annual dividend. The dividend income, minus capital gains tax and any investment-related expenses, constitutes the taxable capital income.
Further examples: interest on savings accounts, gains from investment fund units
Income from letting real estate or movable property, minus deductible expenses such as depreciation (AfA), loan interest, and maintenance costs. Losses can be offset against other income categories.
Example: A property owner rents out several apartments. Taxable income equals rental receipts minus maintenance costs, mortgage interest, and depreciation allowances.
Further examples: leased plots of land, subletting, rented garages or parking spaces
The catch-all provision of § 22 EStG – but only for the types of income explicitly listed there. Income that does not fall under any of the seven categories is not taxable at all (e.g. lottery winnings).
Example: Gains from private disposal transactions – such as selling shares held for less than one year (within the speculation period). The difference between the sale price and the purchase price, minus transaction costs, constitutes the taxable income.
Further examples: statutory pensions, maintenance payments (Realsplitting), distributions from retirement savings contracts
The calculation of taxable income in Germany is done in several steps and takes into account different types of income, expenses, deductions and allowances. Here is a simplified illustration of the calculation process:
1. Determination of income from various sources
First, the income from all seven types of income is compiled: agriculture and forestry, business, self-employment, employment (e.g. salary), capital assets, renting and leasing and other income (e.g. pensions, maintenance payments). However, it is rare for income to come from all seven sources. Usually only a few sources occur at the same time.
2. Deduction of income-related expenses
Income-related expenses can be deducted from income. Income-related expenses are expenses that serve to acquire, secure and maintain income. These include, for example, travel costs to work, training costs or expenses for work equipment.
3. Total amount of income
After deducting the income-related expenses from the income from the various sources, the total amount of income is obtained.
4. Deduction of special expenses and extraordinary expenses
Special expenses and extraordinary expenses can be deducted from the total amount of income. Special expenses include contributions to health and long-term care insurance, pension contributions, donations and church tax. Extraordinary expenses are major expenses that a taxpayer inevitably incurs and that exceed the normal standard of living, such as high medical costs.
5. Deduction of allowances
In addition, allowances such as the basic allowance, child allowances or the age relief amount can be deducted to reduce the tax burden.
6. Taxable income
After deducting all allowable amounts from the total amount of income, the taxable income is obtained. The tax rate is applied to this income to calculate the income tax.
Simplified calculation based on § 2 EStG for employment income – enter your figures:
Of this, 34,422 € exceeds the basic personal allowance of €12,348 (2026) – only this portion is taxed progressively at 14–45 %.
Simplified model with sample values, as of 2026 – excluding pension provisions, church tax, and special cases. Not tax advice.
Tax-free amounts are amounts that are deducted from taxable income before income tax is calculated. They are used to take into account the tax-free basic needs of a taxpayer or certain personal circumstances. There are different types of tax-free amounts that can be applied to taxable income depending on the taxpayer's individual situation. The amount and applicability of these tax-free amounts can change over the years, depending on legal adjustments.
These are some of the most important tax-free amounts in Germany:
1. Basic tax-free allowance
2. Child allowance
3. Single parent relief amount
4. Employee lump sum
5. Saver's lump sum
6. Relief amount for single parents
These tax free amounts are automatically taken into account in the income tax return, provided that the requirements are met and the corresponding information is provided. They reduce the taxable income and thus the tax burden. It is important to check the current tax free amounts and requirements regularly, as legal regulations can change.
Income tax in Germany is calculated using a progressive tax scale, which means that the tax rate increases as income rises. There are different tax brackets and rates that apply depending on the amount of taxable income and personal situation (e.g. single, married). As of 2023, here are the main features of the German income tax scale:
These figures are general guidelines. The actual tax burden may vary depending on individual circumstances (e.g. special expenses, extraordinary expenses, tax-free amounts, taxable income). There are also different tax brackets for different life situations, which can influence the amount of tax prepayments. For an exact calculation of the tax burden on taxable income or for specific questions, it is advisable to consult a tax advisor or use an up-to-date tax calculation program.
Taxable income below the basic tax-free allowance is the amount of income below the tax-free threshold up to which no income tax is levied. In Germany, the basic tax-free allowance is the amount of income up to which there is no tax liability in order to make the minimum subsistence level tax-free. If a person's taxable income is below this amount, they do not have to pay income tax. The basic tax-free allowance therefore serves to protect the taxable minimum subsistence level.
Parental allowance is not considered taxable income in Germany as it is tax-free. However, it is subject to the progression proviso, which means that it is taken into account when determining the tax rate applied to other taxable income. This can lead to an increase in the tax rate on other income and thus indirectly increase the tax burden, even though the parental allowance itself is not taxed.
You will find your relevant taxable income in the income tax assessment notice issued by the tax office after your tax return has been submitted and checked. The tax assessment notice contains detailed information about the calculation of your tax liability, including the taxable income on which the tax was calculated.
To reduce your taxable income, you can claim income-related expenses, special expenses, extraordinary expenses and tax free amounts such as the employee lump sum, pension expenses and donations. You can also deduct depreciation for items used for professional purposes and costs for professional training. Claiming child allowances and using tax-privileged pension products are further ways to reduce your tax burden.
Taxable income refers to the amount that remains from gross income after deducting all permitted expenses, tax-free amounts and lump sums and to which income tax is applied. It is therefore neither directly the gross income nor the net income in the everyday sense (net income is often understood as the income after deduction of taxes and social security contributions).
Here is a brief explanation:
The taxable income is therefore a calculated figure that forms the basis for determining the income tax liability. It is the result of a calculation process that aims to fairly capture the taxpayer's taxable capacity.
