Advice on declaring Freelance income from the UK in Poland [15]
I'm resident in Poland so you pay tax where you live for more than 183 days or something like that... So being a freelancer in the UK is not really possible.
Found this on the Polish Ministry of Finance Website:
"The lump sum tax rates on registered revenue could be for example:"
20 % for revenue from freelance professions" 8,5 % for revenue from services, incl. catering connected with the sale of beverages containing over 1.5 % alcohol,
5,5 % for revenue from production and construction works,
3,0 % for catering services, with the exception of revenue from the sale of beverages containing over 1.5 % of alcohol.

Its not totally clear but it seems to me that you can pay tax in a lump sum if you are a freelancer... just not sure how it works if you started earning income before officially registering as a sole trader...
