I'm a US citizen working as self-employed in Poland and in order to prove my exemption from paying US social security taxes, I must obtain a 'certificate of coverage' from ZUS.
Has anyone in a similar situation had any experience with this? If so it would be great to hear some advice about the best way to proceed.
It would be great to know how long this would take and how much of a hassle it is. From what I understand I must write to ZUS, and the certificate must be in English.
Looking forward to hearing from anyone who can provide some insight into this.
As long you spend more than 330days abroad and earn less than 90k USD per year, you don't have to pay a single dime to US tax office, yet still have to do your yearly declaration.
