Taxed at source only for a half-year

In 2021 I had a job in a different canton than my residence. For the first half of 2021 I was taxed at the source, then not anymore.

I know that I have to file my tax declaration for 2021 in my canton of residence on 31.12.2021. But what about the period that I was taxed at the source: will it also be taken into account by the tax declaration in the canton of residence or shall I also file a separate Antrag auf Quellensteuer-Rückerstattung?

I believe my question has an obvious answer, but I just want to be sure

It should be taken in account in your canton of residence on 31-Dec, where you will file your tax return. The previous canton should pay the other canton. It can take time to have your final decision because of this.

Many thanks 🙌

I also suspected that I had to do only one tax declaration, but I was not so sure...
