Tax and compliance calendar 2026 for companies in Poland
This calendar lists every deadline that applies to a company in Poland in 2026: national tax and reporting duties alongside EU-wide regulations - such as the AI Act, NIS2 and the Cyber Resilience Act - that apply across the whole EU.
Recurring obligations - monthly VAT returns, quarterly filings, annual reports - are expanded into their individual due dates for the year using the rule shown on each deadline's own page. This calendar does not shift dates that fall on a weekend or public holiday; always check the linked official source for the exact filing deadline.
From 1 January 2026, registered electronic delivery (e-Doręczenia) replaced ePUAP as the primary channel Polish public authorities use to correspond with businesses and citizens that hold an e-Doręczenia address. Correspondence sent to an entity's e-Doręczenia address has the same legal effect as registered mail; relying only on the old ePUAP inbox after the cutover can be legally ineffective for parties obligated to hold an e-Doręczenia address.
Poland's minimum monthly wage for full-time work is PLN 4,806 gross from 1 January 2026 (up from PLN 4,666 in 2025), with a minimum hourly rate of PLN 31.40 for specified civil-law contracts, set by a Council of Ministers regulation of 11 September 2025.
Since 1 April 2026 all businesses in Poland must issue B2B invoices through the National e-Invoicing System (KSeF) in the FA(3) XML schema; the system assigns the legal invoice number and the buyer receives it via KSeF. Only micro-entrepreneurs with monthly sales up to PLN 10,000 (gross) have until 2027. Paper and PDF invoices are no longer valid B2B invoices.
From 1 April 2026, providers of parking services in Poland, including automated/unattended parking with payment machines, lost their exemption from the obligation to record sales on a fiscal cash register and issue a receipt.
The amendment to Poland's Act on the National Cybersecurity System (Ustawa o krajowym systemie cyberbezpieczeństwa, KSC), transposing the EU NIS2 Directive (EU) 2022/2555, was adopted by the Sejm on 23 January 2026, signed by the President on 19 February 2026, published in the Journal of Laws on 2 March 2026, and entered into force on 3 April 2026. It expands the categories of 'key' and 'important' entities subject to cybersecurity risk-management and incident-reporting duties.
Directive (EU) 2023/970 requires every employer in the EU, whatever its size, to give job applicants the initial pay or pay range for the role before the interview or in the job ad, and bans asking applicants about their pay history. Workers also get the right to ask, in writing, for their own pay level and the average pay level by sex for people doing the same or equal-value work.
Until mid-2026, parcels worth up to €150 sent to EU consumers from outside the EU were exempt from customs duty (VAT has already been due on them since 2021). Council Regulation (EU) 2026/382 removed that exemption and, from 1 July 2026, applies a flat transitional duty of €3 per item to such low-value consignments, ahead of full ad-valorem tariffs once the EU Customs Data Hub is operational (targeted around mid-2028).
The Cosmetic Products Regulation's list of fragrance allergens that must be individually named on the label grows from about 26 to more than 80 substances, whenever present above 0.001% in leave-on products or 0.01% in rinse-off products. New cosmetic products placed on the market from 31 July 2026 must use the expanded list; stock already on the market before that date can still be sold until 31 July 2028.
Directive (EU) 2024/1799 applies nationally from 31 July 2026. Manufacturers of products with EU repairability requirements (washing machines, fridges, dishwashers, vacuum cleaners, displays, phones, tablets, servers, e-bike batteries) must repair them at a reasonable price and time even outside the legal guarantee. When a consumer chooses repair under the guarantee, the guarantee is extended by 12 months. Sellers must offer repair when it is not more expensive than replacement.
Users must be told when they interact with an AI system (chatbots, voice bots). AI-generated or manipulated images, audio, video and text must be marked in a machine-readable way, and deepfakes must be labelled. Since the same date national authorities can fine companies for most AI Act breaches.
Regulation (EU) 2025/40 applies directly in all Member States. Packaging must be minimised (e-commerce parcels max 40% empty space), food-contact packaging with PFAS above limits is banned, every packaging type needs a conformity assessment and technical documentation, and producers must register for extended producer responsibility in each country where they place packaged goods. Further deadlines follow (harmonised labels 2028, recycled-content minimums 2030).
Businesses whose intra-EU trade in goods (arrivals or dispatches) exceeds the basic statistical reporting threshold set annually by GUS must file a monthly INTRASTAT declaration covering the value and nature of goods moved to or from other EU member states, by the 10th of the following month.
Manufacturers of products with digital elements (hardware and software, including SaaS-connected devices and standalone apps) must report actively exploited vulnerabilities and severe security incidents through ENISA's single reporting platform: early warning within 24 hours, full notification within 72 hours, final report within 14 days (vulnerabilities) or one month (incidents). It applies to products already on the market.
Connected products (IoT devices, machines, vehicles, smart appliances) placed on the market from this date must be built so that the data they generate is easily, securely and free of charge accessible to the user, directly on the device where feasible. Since September 2025 users can already request their data and share it with third parties, and pre-contract information about generated data is mandatory.
Employers must calculate and transfer employee and employer PPK (Employee Capital Plan) contributions, deducted from salaries paid during the month, to the selected PPK financial institution by no later than the 15th of the following month.
Employers must submit the ZUS settlement declaration (ZUS DRA) together with personal monthly reports (ZUS RCA/RSA/RPA), and pay social and health insurance contributions for the reporting month, by a deadline that depends on the payer's legal form: the 15th of the following month for payers with legal personality (e.g. sp. z o.o.), the 20th for other payers (sole traders, personal partnerships), and the 5th for budget units.
CIT taxpayers must calculate and pay a monthly advance on corporate income tax by the 20th of the following month. Small taxpayers (mali podatnicy, turnover up to EUR 2 million) may instead elect quarterly advances, due by the 20th of the month after each quarter, provided they notify the choice via their annual CIT return.
Employers with at least 25 full-time-equivalent employees whose disability-employment rate is below the statutory 6% must calculate, declare (DEK-I-0 or the applicable DEK-I-a/b form), and pay their monthly contribution to the State Fund for Rehabilitation of Disabled Persons (PFRON) by the 20th of the month following the month the obligation arose.
Employers acting as PIT withholding agents (płatnik) must calculate, withhold and pay personal income tax advances on salaries and other reportable employment income by the 20th of the month following payment. There is no monthly PIT-4R filing - the withheld amounts are only reported once a year in the annual PIT-4R declaration.
VAT-registered businesses in Poland must submit the JPK_V7M structured VAT records-and-declaration file and pay any VAT due by the 25th of the month following the settlement period. Small taxpayers may instead settle quarterly as JPK_V7K, though the records portion is still sent every month.
VAT-registered businesses that made intra-EU supplies of goods, intra-EU acquisitions of goods, or reverse-charge B2B services in a given month must file a VAT-UE summary information return listing the counterparties and values, by the 25th of the following month. No filing is required for a month with no such intra-EU transactions.
Directive (EU) 2024/825 amends EU consumer-protection law (the Unfair Commercial Practices Directive and the Consumer Rights Directive) to ban generic environmental claims not backed by recognised excellent environmental performance (e.g. 'climate neutral', 'eco-friendly', 'green' used without substantiation), bans claims based purely on carbon-offsetting, and requires sustainability labels to come from a certification scheme or a public authority rather than being self-created. It also bans planned-obsolescence practices and requires clearer product durability/reparability information.
From 1 October 2026, sole traders and other businesses registered in Poland's CEIDG (Central Registration and Information on Business) before 1 January 2025 must hold and use a registered electronic delivery (e-Doręczenia) address for official correspondence with public authorities, completing the phased rollout that already covers new CEIDG registrations, KRS-registered companies and public-trust professions.

Does this calendar include EU-wide obligations, or only national ones?
Both. It combines every national deadline for this country with EU-wide regulations - such as the AI Act or NIS2 - that apply to companies here regardless of country.
How are recurring deadlines like monthly VAT returns shown?
Each recurring obligation (a monthly VAT return, a quarterly filing) is expanded into its actual due date for every month, quarter or year it applies, using the recurrence rule published on its own deadline page.
How current is this calendar?
Every entry links to its official source and shows a last-verified date. Dates can move, so always confirm against the official source before relying on one.
