Tax Rates (Lohnsteuer)
A basic personal allowance is deducted from taxable income; it is EUR 8,354 for single persons and EUR 16,708 for married couples.
The minimum tax rate is 14%. To start with, this rate increases progressively up to a rate of 42% for a taxable income of EUR 52,882 / EUR 105,762 (single persons/ married couples). Above this income, their are flat rates.
NOTE: The above table is valid for year 2022. For earlier years, there are little different tax rates.
As you can note above the tax allowance is double for married person. The basic principal is that income is divided half between couple to calculate income tax liability. You may be wondering about the tax range between the income level. This is a different concept than India, it is called progressive tax. See the progressive chart graph here.
