Tax refers to the compulsory monetary contribution made to the revenue of a country that is levied on the residents – it comes from income of the workers, business profits, cost of goods, services and transactions.
In Germany, whether you are a citizen or resident, the law requires you to pay taxes. The Federal Government “Bundersregierung” is in charge of the tax collection, which is done locally by the tax offices called “Finanzamt”. If you are an expat, employed in Germany, you would have noticed the term “Lohnsteuer” on your paycheck. This deduction is the monthly tax on your income. However, if you have your business, second job or a freelancer, then you need to submit the annual tax return, so the government calculates the income tax that you need to pay.
