- From 1 February 2026, e-invoicing via Poland’s KSeF system becomes mandatory, impacting VAT reporting.
- The JPK_VDEK (SAF-T VAT return) schema will require new mandatory invoice reference fields: a KSeF identification number or one of the codes (OFF, BFK, DI).
- VAT returns missing these fields will be rejected, with no grace period, leading to compliance risks and possible penalties.
- Businesses must update their systems and data extraction processes to ensure these fields are included before filing.
- Avalara will update its products, but customers are responsible for ensuring their data includes the required fields.
