Polish tax authorities reminded businesses and sole proprietors of KSeF’s February 2026 rollout in pre-Christmas notices.
Christmas Reminder
I received an unforgettable experience on Christmas Eve Eve. A notice arrived in my e-Delivery inbox from the tax office. The classic saying goes: the innocent have nothing to fear, but anyone opening such a “gift” from this sender, considering the timing, must feel at least a shiver of emotion.
KSeF Implementation
The notice was a polite reminder from the tax office that the KSeF system will begin operating on February 1, 2026. It was not only sent to large companies but also to millions of people running sole proprietorships.
Broad Impact
It’s as if someone deserves a prize for choosing December 23rd for such a notification.
