Poland: INTRASTAT declaration due by the 10th (once statistical thresholds are exceeded)

Re-checked 2026-09-09: stat.gov.pl/intrastat/ redirects to the new.stat.gov.pl homepage; no dedicated Intrastat page was found this session. Current-year PLN thresholds and the 10th-of-month deadline could not be independently re-verified. Verify with GUS/KAS before relying on the exact PLN figures.

Next: 10 September 2026then 10 October 2026, 10 November 2026

Poland-registered importers/exporters trading goods with other EU countries above the annual GUS threshold - most relevant to an e-commerce importer sourcing or shipping stock across the EU at meaningful volume; a small SaaS business with no physical goods trade is not affected.

Poland: ZUS social insurance contributions and DRA declaration due by the 15th (legal persons)

Next: 15 September 2026then 15 October 2026, 15 November 2026

Every Poland-registered ZUS contribution payer, including a self-employed sole trader (JDG) paying only their own contributions; a sp. z o.o. (a capital company with legal personality) falls under the 15th-of-month deadline described here, while sole traders and personal partnerships use the 20th (see the action text below).

Poland: monthly CIT advance payment due by the 20th (quarterly option for small taxpayers)

Next: 20 September 2026then 20 October 2026, 20 November 2026

Next: 25 September 2026then 25 October 2026, 25 November 2026

Poland: e-Doręczenia address becomes mandatory for CEIDG businesses registered before 2025

Applies to sole traders/businesses registered in CEIDG before 1 January 2025. Businesses registering in CEIDG from 1 January 2025 onward, and any pre-2025 CEIDG entrepreneur who filed a CEIDG update request after 30 June 2025, already had to set up an e-Doręczenia address earlier. Companies registered in the KRS had an earlier deadline: 1 April 2025 for those registered before 1 January 2025, and immediately at registration from 1 January 2025 for new KRS entities.

Sole traders (jednoosobowa działalność gospodarcza) and other CEIDG-registered businesses in Poland that registered before 1 January 2025 and have not already set up an e-Doręczenia address.

Poland: VAT OSS Union-scheme return and payment due by the end of the month after each quarter

Re-checked 2026-09-09: podatki.gov.pl/vat/vat-oss/procedura-unijna-oss still returns a 404 (site restructure). The end-of-month-after-quarter deadline is the well-established EU-wide OSS rule, consistent with the same rule confirmed elsewhere in this dataset (e.g. Lithuania, Estonia); not independently re-confirmed against podatki.gov.pl this session.

Next: 31 October 2026then 31 January 2027, 30 April 2027

Poland-registered e-commerce and services businesses selling goods or digital/other services to consumers in other EU countries that have opted into the Union OSS scheme instead of registering for VAT separately in each destination country.

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: annual report to the national GHG/emissions database (KOBiZE) due by end of February

Confirmed 2026-09-09 via kobize.pl's own "Informacja ogólna" page: "Informacje wymienione w punktach 1-12 dotyczące poprzedniego roku kalendarzowego są wprowadzane do Krajowej bazy przez podmioty korzystające ze środowiska w raportach rocznych składanych do końca lutego każdego roku" (prior-year data is submitted in annual reports filed by the end of February each year) -- matches the dataset's end-of-February deadline.

Next: 28 February 2027then 29 February 2028, 28 February 2029

Businesses operating emission sources in Poland - in practice this reaches far beyond heavy industry, since it covers company vehicle fleets and building heating/generator equipment above minor thresholds, making it a commonly overlooked obligation for ordinary office-based companies.

Poland: annual BDO report on packaging and products due 15 March

Next: 15 March 2027then 15 March 2028, 15 March 2029

Poland: annual environmental-use fee (opłata za korzystanie ze środowiska) due by 31 March

Re-checked 2026-09-09: gov.pl/web/gov/zloz-sprawozdanie-o-korzystaniu-ze-srodowiska-oraz-wniesionych-oplatach now redirects to the gov.pl homepage (the page appears to have been removed or moved). The 31 March deadline and the de-minimis fee threshold could not be independently re-confirmed this session.

Next: 31 March 2027then 31 March 2028, 31 March 2029

Businesses operating vehicles or other emission/water-use sources in Poland above the de-minimis threshold - like the KOBiZE report, this reaches beyond heavy industry to ordinary companies with a company vehicle fleet.

EU Deforestation Regulation: due diligence applies for micro and small enterprises

Postponed by Regulation (EU) 2025/2650; micro/small primary operators in low-risk countries only file a one-off simplified declaration. Tag scoping clarified 2026-09-08: sectors/flags cannot express 'only these 7 commodities' in this dataset's tag vocabulary, so a general importer in the listed sectors can still match by tags alone — read whoIsAffected below to check whether your actual goods are covered before treating this as applicable.

ONLY micro and small importers, wood and furniture makers, coffee roasters, chocolate makers, printers and retailers that actually deal in EUDR Annex I commodities and their derived products: cattle (incl. leather), cocoa (incl. chocolate), coffee, palm oil, rubber (incl. tyres), soy, and wood (incl. furniture, paper, printed products). This does NOT cover general consumer goods, electronics, textiles or other imports/exports outside that Annex I list — e.g. a general e-commerce importer of unrelated goods (even one that also imports batteries) is out of scope even though the sector/flag tags below cannot fully exclude that profile.

Indicative. Per the Commission's ESPR working plan 2025-2030 delegated acts are targeted for iron & steel in 2026 and textiles, tyres and aluminium in 2027; obligations typically apply ~18 months after adoption. As of August 2026 no delegated act has been adopted
