What is the double taxation agreement (DTA)?
A double taxation agreement (DTA) determines where and how income is taxed when work is carried out in a foreign country. To avoid double taxation, Germany has concluded such agreements with over 70 countries.
If you are taxable in the neighbouring country, you will be exempt from tax in Germany. If you pay taxes on your cross-border employment in Germany, you do not have to pay tax on the income again in the neighbouring country. However, the income taxed abroad is included in the progression clause in Germany. This means that a total income is calculated from the income as a cross-border commuter and other income in Germany. This total income results in a higher tax rate, but only the income received in Germany is taxed at this rate.
Exceptions: For France, Austria and Switzerland, a special cross-border commuter regulation applies under the respective double taxation agreement. If you work in France or Austria, you do not have to pay taxes there, but must declare the wages in your German tax return and pay tax on them normally. Civil servants or public sector employees, however, pay tax on their income in the country where they work, as the principle of the paying state applies.
If you work as a cross-border commuter in Switzerland, your employer may deduct a wage tax of 4.5 percent, which is credited against the tax in Germany. If you are a civil servant or public sector employee, you must pay tax on your income entirely in Germany.
Please note that there are special regulations for cross-border commuters during the coronavirus period, as many employees are or were working from home and do not or did not commute daily (see also: Double taxation agreements and other agreements in the tax sector).

What is tax-free income under DBA/ATE?
This refers to tax-free wages under double taxation agreements (DTA) or the decree on employment abroad (ATE). A DTA stipulates how employees working abroad must tax their income to avoid double taxation. Wages for work abroad can be tax-free under the ATE if there is no double taxation agreement with the relevant country and the work lasts for at least three consecutive months. Illness or leave do not affect the duration of employment but are not counted towards the three-month period.
If your salary is taxable abroad, you will be exempt from tax in Germany under the DTA or ATE. However, income taxed abroad is included in the progression clause in Germany. This means that a total income is calculated from the foreign income and other income in Germany. This total income results in a higher tax rate, which is only applied to the income earned in Germany.
Exceptions:
For France, Austria, and Switzerland, a special cross-border commuter regulation applies under the double taxation agreement. If you work in these countries, the wages are taxed in the country of residence, Germany.
In Switzerland, the employer may deduct a wage tax of 4.5 percent, which is credited against the tax in Germany.
Civil servants and public sector employees always tax their income in the country where they work, as the principle of the paying state applies.
