I am an Italian citizen, resident in the UK since 2007 and now with settled status.
I started working for a Polish company 2 weeks ago, and still did not receive my first pay check.
The company requested a Certificate of Fiscal residence - Relief from Polish Tax.
I've requested this on on-line 8/9/23 but I've only received a letter of confirmation of residence dated 13/9/23.
My new company legal department says that is not sufficient to get relief from double taxation.
How do I get the appropriate CoR?
Thank you for your help
