Credit Swiss withholding tax
Hello,
my question is regarding the crediting of Swiss withholding tax.
I live and work (not self-employed) in Germany.
My husband works (not self-employed) and lives in Switzerland, not a cross-border commuter.
Withholding tax is deducted from his salary.
However, his main place of residence is in Germany.
In Germany, we file a joint tax return.
Swiss income is taken into account for the calculation of the tax rate in Germany (progression clause).
I have now learned that "if there is a double taxation agreement with the foreign country, the crediting of the foreign tax may be provided for, taking into account the maximum credit amount."
My question is: in which forms and lines should the withholding tax be entered so that the crediting method applies?
Are the attachments N and N-AUS sufficient or are additional attachments (AUS?) required?
Thank you!
