Poland: confirmed, your date is 1 January 2027
In Poland you will need to issue structured e-invoices (FA(3) structured XML) from 1 January 2027.
You must already be able to receive a structured e-invoice (since 1 February 2026), the duty to receive arrives before the duty to issue.
Until your issue date, a compliant invoice PDF (including reverse charge) is valid. euinvoice creates compliant PDFs today, and Pro users can export Factur-X (EN 16931) e-invoices.
