Poland: JPK_CIT digital accounting-books reporting becomes mandatory for remaining CIT taxpayers

Updated 2026-09-09: primary-source-confirmed via api.sejm.gov.pl -- the Ustawa z dnia 15 maja 2026 r. (Dz.U. 2026 poz. 779), in force 2026-07-01, amended the CIT Act's JPK_CIT submission-deadline provision. The submission deadline for the structured accounting books is no longer tied to the CIT-8 filing deadline; it is now "do końca siódmego miesiąca po zakończeniu roku podatkowego" (the end of the 7th month after the tax year ends) -- e.g. 31 July for a calendar-year filer, not ~31 March. This entry's 2027-01-01 date still correctly marks when the final phase (remaining CIT taxpayers) becomes obligated to keep the books electronically, but the first SUBMISSION under that phase now falls around 31 July 2028 (7 months after the FY2027 year-end), not alongside CIT-8 the following spring. Separately: this entry only models the final (2027) phase. A small VAT-registered CIT taxpayer (e.g. a small SaaS or e-commerce sp. z o.o. already filing JPK_V7M) plausibly falls into the EARLIER "other CIT payers already obligated to file JPK_VAT" phase (tax years starting after 31 Dec 2025, i.e. FY2026), which is not represented by a separate dataset entry -- this phase-2 gap could not be independently confirmed to primary-source standard this session (podatki.gov.pl's JPK page loaded with no extractable article text) and is flagged for a follow-up audit rather than guessed at.

Polish CIT taxpayers, including smaller companies and non-legal-person entities keeping accounting books, not already brought into scope by the 2025 (large taxpayers/tax capital groups) or 2026 (other JPK_VAT-obligated CIT payers) phases.

Poland: 2027 minimum wage proposed at PLN 4,950; final regulation due by 15 September 2026

The Rada Dialogu Społecznego (Social Dialogue Council) did not reach a unanimous position, so under the Minimum Wage Act the Council of Ministers must set the 2027 figure by regulation no later than 15 September 2026, and cannot set it below the PLN 4,950 gross / PLN 32.30 hourly figure it already proposed to the social partners. As of this run (2026-09-08), the confirming Dziennik Ustaw regulation had not yet been published - treat PLN 4,950 as the legal floor, not yet the final confirmed figure.

Every employer in Poland with staff paid at or near the minimum wage, regardless of sector.
