Polish Senate backs limiting tax authority access to bank account data
Contents

On Friday 6 November 2026 the Polish Senate proposed amendments to a bill restricting the National Revenue Administration (KAS) from accessing data on bank accounts. The Sejm must now vote on the amendments.

How the Senate voted

95 senators backed the bill amending the KAS Act and the Banking Law. None voted against and none abstained. According to Bankier.pl, the amendments are editorial.

The amendment concerns tax authorities' access to bank data.

What the amendment changes

The aim is to limit the tax authority's access to account information. Under the rules, data will be available for people suspected of a crime or offence, including fiscal ones. It also covers people who are not suspects but whose data a court has allowed a bank to pass to the tax authorities. Access will therefore not extend to every individual.

Earlier stage of the legislation

The Sejm had already passed the bill. According to Bankier.pl, 418 MPs voted in favour, 18 abstained and none were against. After the Senate, the bill returns to the Sejm, which will consider the amendments. The sources do not give a date for that vote or for the rules taking effect.

What this means for you

The changes concern Polish tax authorities and accounts held at Polish banks. They may matter to people living in the UK who still keep an account in Poland. The sources do not mention accounts at UK banks or information exchange with HMRC. The rules have not yet been finally adopted.
