What the client should know
Mandatory KSeF began in stages in 2026: generally 1 February for the largest taxpayers and 1 April for other entrepreneurs, subject to the statutory small-invoice transitional rule through 2026.
KSeF readiness is not only software installation; authorisation, corrections, outages and internal approval controls must also work.
