Was sich an diesem Datum ändert

PolenPoland KSeF

Poland: KSeF e-invoicing mandatory for all VAT taxpayers (except the smallest micro-firms)

Since 1 April 2026 all businesses in Poland must issue B2B invoices through the National e-Invoicing System (KSeF) in the FA(3) XML schema; the system assigns the legal invoice number and the buyer receives it via KSeF. Only micro-entrepreneurs with monthly sales up to PLN 10,000 (gross) have until 2027. Paper and PDF invoices are no longer valid B2B invoices.

Connect your ERP or invoicing tool to KSeF 2.0 with authentication tokens or a qualified signature, implement the FA(3) schema and offline24 fallback mode, and train staff on retrieving purchase invoices from KSeF. Use the 2026 penalty-free period to fix errors.

PolenPoland fiscalisation rules (kasy fiskalne)

Poland: mandatory fiscal cash registers extended to parking services

From 1 April 2026, providers of parking services in Poland, including automated/unattended parking with payment machines, lost their exemption from the obligation to record sales on a fiscal cash register and issue a receipt.

If you operate or manage paid parking (including via a payment machine), register a fiscal cash register (an online or virtual cash register can be used) and ensure every parking payment is recorded and a receipt is issued or offered electronically. Vending/ticket-machine operators should plan for the same obligation from 1 April 2027.
