If you're a full-time employee, then income tax in Germany is deducted "at source", meaning it's taken out of your paychecks by your
employer.
If your employment situation is a bit more complicated, such as having multiple jobs, being self-employed, or running your own
business, then you must calculate and file your own taxes.
If you need to submit a tax declaration for 2021, the deadline is October 31st 2022 if you file without the help of a tax advisor,
or August 31st 2023 otherwise.
You can file a tax declaration by using the official online form
ELSTER (Elektronische Steuererklärung), hiring
a tax advisor, joining a tax assistance association (Lohnsteuerhilfeverein), or using third-party software.
You can quickly estimate your taxes using our German tax calculator above!
