What a buyer pays, in short
On a resale the notary collects 2% PCC on deed day, so you do not file PCC-3 yourself. A home abroad removes the first-home relief. In Poznań the 2026 property tax is 1.25 PLN per m² a year, and IN-1 goes to the city within 14 days. A sale is taxed at 19% of income if five years from the end of the purchase year have not passed.
