Poland's tax authority ran roughly 2.3 million automated verification checks in 2025 using JPK and KSeF data, about 19 a minute, and recovered nearly 11 billion zloty in arrears, up 25% on the prior year.
Why It Matters
These are remote checks, not site visits: KAS cross-references your JPK files, KSeF invoices and online cash register data to flag mismatches before an inspector ever calls. For a normal SMB this means errors that used to sit unnoticed for years now surface within weeks, and VAT settlements are the authority's stated top priority for 2026.
What To Do About It
Have your accountant reconcile JPK_V7 filings against KSeF invoice data monthly rather than at quarter-end, the gap is exactly what a czynnosci sprawdzajace notice targets first. Transport, construction, textiles and e-commerce are named as the highest-risk sectors right now.
