Lower Silesian tax offices invite entrepreneurs and anyone interested to open days dedicated to the National e-Invoicing System (KSeF). The event is organized by Izba Administracji Skarbowej we Wrocławiu and is intended to explain how the system works and clarify the most frequently raised questions.

The meetings are scheduled for three dates: Saturday, January 24, Sunday, January 25 and Saturday, January 31. On these days, the offices will be open from 9:00 a.m. to 3:00 p.m. The open days will also include KSeF training sessions, which will begin at 11:00 a.m. and last approximately one hour.

Additionally, from January 26 to 30, 2026, all tax offices in the region (excluding specialized tax offices) will provide special consultations with employees responsible for the National e-Invoicing System. During this period, office hours will be extended until 8:00 p.m. to enable people who work standard hours to take advantage of the consultations.

The organizers emphasize that the open days provide an opportunity to speak directly with experts, receive individual explanations and better prepare to use the National e-Invoicing System. Detailed and up-to-date information about the event is available on the ksef.podatki.gov.pl website.
