Total newbie to this but I searched the internet and the forum and I couldn’t find a step by step guide on how to claim my 3a taxes back. My situation: based in ZH, taxed at source, started a 3a with finpension in 2020, I’ve never filed a tax return before.
I got the document from finpension confirming the deposit. Where do I find the tax return form for Zurich? Where do I send it? How/when do I get the money back? Do I fill in an IBAN?
Thanks a lot in advance!
