- Businesses exceeding 200 million PLN in sales in 2024 must issue invoices via KSeF earlier.
- The mandatory invoicing start date depends on 2024 sales, not 2025 as previously thought.
- The threshold for early KSeF implementation is 200 million PLN in gross sales.
- Smaller businesses and those using cash registers have until the end of 2026 to prepare.
- Key dates include November 1, 2025, for certificate issuance and February 1, 2026, for mandatory KSeF use for large businesses.
