Polish tax code and adjudication has been a mess for a very long time. The actual rates have not changed, interpretations do change constantly and you can't get a binding one. There is no such thing. You can officially request some advice from the ministry explaining what the dues are in your case, but what this says is not binding for the revenue service if they choose not to refrain from harassing you with their creative interpretations. Combined with lack of precedence law every issue becomes a potential court gamble (and it is a gamble) if not resolved amicably. That this is new is just hot air about the current government (despicable for other good reasons).
