In early May 2026, the Polish government broadened existing levies, adding a 1% reprographic fee on consumer electronics and raising the RTV subscription charge. Mid-May saw a parliamentary clash over cryptocurrency regulation, while June marked a shift toward structural reforms. The Ministry of Finance rolled out the mandatory National e-Invoice System (KSeF), mandating XML-based invoicing for most taxpayers. By August 2026, KSeF had processed over 340 million invoices from 2 million taxpayers, though integration challenges persisted. High-volume firms faced API throughput limits and file-size caps, while nearly 20% of corrective invoices contained structural or logical errors. Operational concerns regarding KSeF have intensified. Businesses report receiving invoices via PDF or paper outside the system, creating uncertainty regarding input VAT deductions. Security critics highlight that security gateways are managed by Imperva and analytical servers are located in Israel. Additionally, the ability to search for invoices anonymously using five data points is cited as a risk for data theft. While KSeF increases transparency, it is also exposing significant SME debt, with company debt to factoring entities reaching 296.2 million PLN. To support the transition, the Ministry of Finance has ~~extended~~ moved to delay the ~~grace period~~ imposition of administrative penalties for ~~KSeF-related penalties.~~ technical errors or non-compliance. While the system becomes mandatory for all entrepreneurs on January 1, 2027, a draft amendment to VAT regulations has been submitted to the ~~imposition of administrative penalties~~ Sejm to postpone financial sanctions—such as those for ~~technical errors~~ issuing invoices outside the system or ~~non-compliance has been postponed until~~ late submissions—until January 1, 2028. ~~Concurrently, the state is pushing for the digitalization of tax books, requiring computer programs for income tax records for most taxpayers starting after~~ This delay aims to allow businesses, particularly smaller enterprises, more time to adjust accounting systems and staff training. If passed, these regulations are expected to take effect on December 31, 2026.
