VAT-registered companies in Poland on the standard monthly settlement; small taxpayers (mali podatnicy, turnover up to EUR 2 million including VAT) may opt into quarterly JPK_V7K filing instead.
Re-verified 2026-09-09: the old vat-oss/procedura-unijna-oss page 404s; OSS/IOSS guidance moved to podatki.gov.pl/pozostale/tax-free-vat-refund-vap-oss-i-ioss/punkt-kompleksowej-obslugi-oss-i-ioss (reachable), which confirms quarterly Union-scheme filing via its own unique-reference-number format (e.g. PL/PLxxxxxxx/Q3.2021); the end-of-month-after-quarter deadline is the well-established EU-wide OSS rule, unchanged.
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.
Re-verified 2026-09-09: GUS's stat.gov.pl/intrastat page redirects away with no dedicated Intrastat content; filing now runs through puesc.gov.pl (Krajowa Administracja Skarbowa), whose "Złóż zgłoszenie INTRASTAT" service states the declaration is due "nie później niż do 10. dnia miesiąca następującego po okresie [sprawozdawczym]", confirming the 10th-of-month deadline. Current-year PLN thresholds still not independently re-confirmed — verify with GUS/KAS.
Next: 10 November 2026then 10 December 2026, 10 January 2027
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.
Next: 15 November 2026then 15 December 2026, 15 January 2027
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).
Next: 20 November 2026then 20 December 2026, 20 January 2027
All Poland-registered CIT taxpayers (sp. z o.o., S.A. and other CIT payers) generating taxable income during the year.
Manufacturers of any product, software developers and SaaS providers, importers, fulfilment providers and, where no EU manufacturer exists, online marketplaces and distributors.
24 months after the implementing regulations of 2024-11-28 (Art. 5a Reg. 2024/1183); the Commission communicates it as 'end of 2026'
No direct obligation on private businesses yet; companies dealing with public authorities and those doing KYC/onboarding should prepare to accept wallet-based identification.
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.
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.
Next: 15 March 2027then 15 March 2028, 15 March 2029
Companies introducing packaging, packaged goods, batteries, electrical/electronic equipment or vehicles onto the Polish market, and waste generators/handlers registered in BDO.
Next: 31 March 2027then 31 March 2028, 31 March 2029
All Poland-registered CIT taxpayers (sp. z o.o., S.A. and other CIT payers) with a calendar financial year.
Re-verified 2026-09-09 on biznes.gov.pl/pl/portal/ou133 ("Opłaty środowiskowe"): "Wykaz za dany rok kalendarzowy złóż do dnia 31 marca następnego roku", confirming the 31 March deadline. The page also gives exact de-minimis thresholds: no filing required if the calculated annual fee for a given category is at or below PLN 100, and no payment required (but filing still required) at or below PLN 800, under the Prawo ochrony środowiska (2001).
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.
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.
Receiving instant euro payments is mandatory for non-euro-area PSPs from 2027-01-09; sending and VoP from 2027-07-09
Banks and payment institutions in non-euro Member States; businesses in Poland, Sweden, Czechia, Hungary, Denmark, Romania and Bulgaria paying or receiving euros.
Next: 15 July 2027then 15 July 2028, 15 July 2029
All Poland-registered companies in the KRS (sp. z o.o., S.A. and other commercial entities) with a calendar financial year.
Any business that places products on the EU market or exports from it — manufacturers, importers and distributors of any size — with the highest practical exposure for importers sourcing from regions or sectors with documented forced-labour risk.
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
Manufacturers, importers and brands of the first product groups, especially clothing, footwear, steel products, tyres and furniture; retailers will need to display DPP information.
Council Directive (EU) 2025/516; Member States may postpone the platform deemed-supplier rules until 2030-01-01
Marketplaces and booking platforms in accommodation and transport; SMEs selling cross-border in the EU that currently hold several VAT registrations.
Producers and importers of plastic-packaged goods, hospitality businesses, food retailers and e-commerce sellers.
Small, medium and large service providers still relying on pre-2025 contracts or legacy terminals; microenterprise service providers remain exempt.
Regulation (EU) 2025/2509 published OJ 2025-12-12, in force 2026-01-01, applies after a 4.5-year transition; toys placed on the market before that date may continue to be sold
Toy manufacturers, importers, distributors and online sellers/marketplaces, of any size.
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.
Directive (EU) 2024/825 required Member States to transpose by 2026-03-27 and to apply the national transposing measures from 2026-09-27 (Art. 7). Applies as scheduled; on 2026-05-28 the Commission opened infringement procedures against 20 Member States (incl. BE, EE, FR, LV, NL, PL) for late transposition, so national rules may still be catching up — check the national consumer-protection act where you sell.
Any business making environmental or sustainability claims, or displaying sustainability labels, on products or in marketing aimed at EU consumers — most directly online retailers and manufacturers/importers of physical goods.
Anyone who places packaged products on the EU market: manufacturers, importers, distributors, online sellers and fulfilment providers, regardless of size.
Manufacturers and importers of the covered product groups, and all retailers selling them to consumers.
Commission Regulation (EU) 2023/1545 amending Regulation (EC) 1223/2009. New products placed on the market from 2026-07-31 must comply; products already placed on the market before that date may continue to be sold (sell-through) until 2028-07-31.
Manufacturers, importers and 'responsible persons' for cosmetic products sold in the EU (skincare, haircare, fragrance, make-up, toiletries) — cosmetics have their own sectoral regime and are not covered by the General Product Safety Regulation.
Council Regulation (EU) 2026/382 (adopted 2026-02-11, OJ 2026-02-18) deletes the customs duty exemption for consignments up to €150 and imposes a transitional flat duty of €3 per item from 2026-07-01 until 2028-07-01, when the EU Customs Data Hub is due to apply normal, item-specific tariffs instead.
Online sellers and marketplaces that ship low-value parcels directly to EU consumers from outside the EU, and the consumers who receive them; does not affect goods already inside the EU or ordinary B2B shipments cleared through full customs declarations.
All entities obligated to maintain an e-Doręczenia address, including businesses registered in the KRS or CEIDG within scope of the phased mandate, and public-trust professionals (advocates, tax advisers, notaries).
Banks and payment institutions directly; every business that pays or gets paid by bank transfer is affected because payments with a name/IBAN mismatch now trigger warnings and may be delayed.
Ustawa z dnia 26 kwietnia 2024 r. o zapewnianiu spełniania wymagań dostępności przez niektóre podmioty gospodarcze (Polish Accessibility Act) transposes the EU Accessibility Act (EU) 2019/882; the Act's substantive requirements apply from 28 June 2025.
Small, medium and large companies producing, importing, distributing or offering in-scope products or services in Poland, especially e-commerce, banking, telecoms, transport and media; micro-enterprises providing services are exempt.
Microenterprises (fewer than 10 staff and turnover or balance sheet ≤€2m) providing the listed services are exempt from the EAA; microenterprises manufacturing the listed physical products are not. Beyond that: any business selling to consumers online or providing the listed services in the EU — small, medium and large service providers, and product manufacturers of any size.
Manufacturers, importers, distributors, online sellers and marketplaces of non-food consumer products, whatever their size.
Any business offering an online intermediary service to users in the EU: hosting user content, running a marketplace or listings feature, an app store, a search engine, a social network. A micro or small enterprise (fewer than 50 staff, turnover/balance sheet under EUR 10M) is exempt from the Section 3 transparency, recommender-system and advertising duties, and keeps that exemption for a further 12 months after it stops qualifying. A company that only sells its own goods or services online, without hosting third-party content or listings (a typical single-vendor e-commerce store or a SaaS product), is generally not itself an 'intermediary service' under the DSA at all.
