Dear jttraveller,

Life would have been much simple would it have been the process. It takes long time and plus if you are expats working in ch and you want to claim other expenses there are many forms and supporting docs which you will need to submit.

Some canton have online apps but not sure if your canton have one.

Atleast I had to follow this process and got some tax back.

But at last it depends on Canton as every canton have their own TAX dept.
