What to know if you live in Poland

Deposits are covered up to the złoty equivalent of €100,000 per depositor per bank, converted at the average euro rate published by Narodowy Bank Polski on the day the guarantee is triggered, and paid out in złoty whatever currency the account was in. Up to €200,000 is covered for three months after a home sale, a division of property on divorce, an inheritance, a life or accident insurance payout, severance or a pension (BFG).

Interest is taxed at a flat 19% that a Polish bank withholds, so nothing goes in your annual return (podatki.gov.pl). Interest from a bank in another country has no Polish payer, so you declare it yourself at 19% in field 46 of PIT-38 and credit any tax withheld abroad in field 47, capped at the Polish 19%.
