a lot of people recommended me inFakt to do accountability month by month, is there something cheaper than this?
There is a very good online accountant called Taxe.pl. My husband used them when self-employed and they were very efficient. The package he used cost under 100zl per month and they did his monthly income tax and VAT returns and ZUS for that. They send in the relevant paperwork to the tax office and notify you of how much you have to pay.
