All deadlines we track for NIS2 (Poland transposition - Ustawa o KSC). Each entry links to the official source and explains who is affected and what to do.
2 deadlines tracked. Dates are the legally binding application dates.
Medium and large entities in NIS2 sectors (energy, transport, finance, health, digital infrastructure/software, manufacturing, food/agri, and others designated by the Act), plus smaller entities the authorities designate as critical or sole providers of a service.
6 months from the amended KSC's entry into force on 2026-04-03; this deadline was extended from an originally proposed 3 months during the Sejm's second reading. Entities that qualify later must still register within 6 months of first meeting the criteria - an ongoing rule, not only a one-off deadline for this initial batch.
Medium and large companies in NIS2 sectors that are or become in scope of the amended KSC, plus smaller entities designated as critical or sole providers of a service.
