avenues to save taxes in Poland?
Lots especially in terms of small tax deductible expenses, gifts to family members, etc. You do need a specialist tax adviser - and a good one, since the goalposts are always shifting and loopholes being closed. Any information from me on deductibles and tax breaks is likely to be out of date. I would suggest you keep any existing savings or investments in a jurisdiction that does not disclose anything to the Polish tax office.
