Sources: 4. Developments: 2. Polish tax authorities have intensified monitoring of bank account operations and cryptocurrency transactions, specifically targeting profits on platforms like Zondacrypto. Officials have utilized the Common Reporting Standard to exchange data with OECD member states to detect income hidden in foreign jurisdictions, with a focus on settlements from 2021. Following these increased scrutiny efforts, the Polish Sejm amended the National Revenue Administration Act and banking laws. These new regulations restrict the ability of tax authorities to inspect bank accounts. Under the amended laws, banks must provide information regarding a “suspect” rather than a broadly defined “natural person.” Additionally, tax officials are now required to obtain a court order to request information from banks during preparatory proceedings involving potential tax crimes or fraud. ## Timeline ### 2026-10-31: Poland implements new laws limiting tax authority access to bank accounts Poland has amended laws to restrict tax authorities' access to bank accounts, now requiring a court order to obtain information regarding suspects during preparatory proceedings. 2 sources. https://clstr.news/cluster/poland-implements-new-laws-limiting-tax-authority-access-to-bank-accounts ### 2026-10-24: Polish tax authorities increase scrutiny of bank transfers and cryptocurrency Polish tax authorities are increasing scrutiny of bank transfers and cryptocurrency transactions, utilizing the OECD's Common Reporting Standard to monitor foreign accounts and prevent tax evasion. 2 sources. https://clstr.news/cluster/polish-tax-authorities-increase-scrutiny-of-bank-transfers-and-cryptocurrency --- Cite as: Polish tax authority oversight and regulation.
