Does anyone know if it is possible to view your "account" online relating to your ZUS and tax payments. I don't trust the fact that I'm paying these things every month but getting absolutely no confirmation whatsoever from either of the relevant authorities
If you're a private person, you can just go to them and ask them for a copy of your payments.
If you have a business, then your accountant should have access to ZUS records (mine does..) and they should also be able to get a copy of your payments to the tax office. Or of course, you can just go to them.
But online, no, it's not possible. Is it actually possible in most countries?
