CEIDG in Poland 2026: registration, data changes, suspension

CEIDG is Poland's free register for sole traders. Your entry appears by the next working day; most changes are due in 7 days. Also suspension, closing, PKD.

CEIDG (Centralna Ewidencja i Informacja o Działalności Gospodarczej, the business register for sole traders) is the public register of JDGs (jednoosobowa działalność gospodarcza, a sole proprietorship). The application is free, and the entry appears no later than the working day after the application is received. You may start trading on the day you file. Most data changes must be reported within 7 days. Switch your PKD codes to PKD 2025 by 31 December 2026, because after that CEIDG will switch them automatically and, where that is not possible, remove the entry.

What CEIDG is and what follows from it

CEIDG contains only entries of people running a JDG and partners in civil-law partnerships (spółka cywilna). The register is kept by the minister responsible for the economy (art. 2 of the CEIDG Act), and applications are handled through the Biznes.gov.pl portal.

The CEIDG-1 application works as a "single window": it also covers the NIP and REGON registration and the contribution payer registration with ZUS (the social insurance institution). You can attach your choice of tax form, VAT-R and your insurance registration.

Data in CEIDG is presumed to be true. You are liable for damage caused by a false entry or by reporting a change late (art. 16 of the CEIDG Act). The entry is public, so you do not need a certificate merely confirming that your business is in the register (see public entry).

CEIDG entry: how to register a JDG

The application asks for, among other things, your personal data, addresses, PKD codes including the main one, start date, tax office and the data for an e-Doręczenia (electronic delivery) address. You give your email if you have one; phone and website only if you want to. CEIDG publishes contact details only with your consent.

You can file online:

on Biznes.gov.pl (log in via Login.gov.pl, sign with a trusted profile, qualified signature or personal signature);
in the mObywatel app, with limitations (e.g. no VAT-R and no ZUS registration);
through selected banks and accounting firms (the CEIDG entry only).

When registering online you cannot act through an authorised representative.

Paper applications are an unclear point. The CEIDG Act (Dz.U. 2026 item 30, art. 8(2)) still allows you to file at a municipal office (gmina) or to send it by registered post with a notarised signature. The amending act (Dz.U. 2026 item 507) leaves only the electronic form, but not until 1 November 2028. Biznes.gov.pl, however, already says that registration can only be filed electronically, except for an application for a minor. Before filing on paper, ask the gmina whether it will accept it.

From 1 November 2026 a foreign person filing the application must have a PESEL number or, if none was assigned, an identifier issued by an EU member state for cross-border identification. Details: registration from 1 November 2026.

You register for insurance with ZUS within 7 days of starting the business. The whole start-up process is covered in the guide how to set up a JDG step by step.

Changing data in CEIDG: deadlines

The deadline depends on the type of data (art. 15 of the CEIDG Act). Within 7 days of the change you report:

first name and surname;
additional words in the business name;
citizenship;
the address for service, the address of your fixed place of business and of any additional places;
your email and other contact details you provided;
PKD codes.

Without delay, no later than the next working day, you report the details of a succession manager (zarządca sukcesyjny), if one has been appointed. At a time that suits you, but in line with the facts, you report changes such as the start, suspension and resumption dates.

Several changes made on the same day can go in one application. CEIDG updates your name (from the PESEL register) and addresses (from TERYT, where possible) by itself.

PKD 2025. Under art. 12 of the Act of 21 November 2025 (Dz.U. 2025 item 1792): if you do not change the codes in your entry to PKD 2025 by 31 December 2026, CEIDG will change them automatically by 31 January 2027, where possible. Where that is not possible, the entry will be removed ex officio after 31 January 2027.

Suspending and resuming the business

You can suspend a JDG if you have no employees, or if you employ only people on the leave types listed in art. 22(2) of the Entrepreneurs' Law (including maternity, parental and childcare leave). The suspension is for an indefinite period or for a fixed period of at least 30 days (art. 23(1)). If the suspension covers only the whole of February, the minimum is the number of days in February that year.

During suspension you do not carry on the business and do not earn current revenue from it. You may collect receivables and must pay liabilities that arose before the suspension; you may also sell your own fixed assets (art. 25). ZUS prepares the deregistration forms (ZWPA, ZWUA, ZCNA) itself, based on the CEIDG application.

If you give an end date in the application, CEIDG records the resumption ex officio from the following day. Without an end date, resumption requires your application.

Removal from CEIDG, i.e. closing the JDG

You apply for removal once you have actually stopped all business activity, including in a civil-law partnership. According to Biznes.gov.pl you can file at any time, in line with the facts: online, at a gmina, or by post with a notarised signature. It is free. Removal takes effect no later than the working day after the application is received, and CEIDG notifies the tax office, GUS and ZUS.

CEIDG generally deletes a removed entry after 10 years, unless you file a new entry in that time. Settlements after closing are covered in the guide how to close a JDG.

Example: moving, PKD and a winter break

Anna has PKD 2007 codes. On Monday 16 November 2026 she moves her fixed place of business.

New address. The deadline is 7 days from the change, counted from the next day: 16 November + 7 days = Monday 23 November 2026.
PKD. In the same application she changes her codes to PKD 2025 before 31 December 2026, so she does not wait for the automatic switch.
Suspension. A break from 1 to 20 December 2026 is 20 days, less than the 30-day minimum. The period from 1 to 31 December 2026 is 31 days, so it is allowed.
February. The whole of February alone, from 1 to 28 February 2027, is 28 days and is also allowed, because February 2027 has 28 days.

FAQ

Is a CEIDG entry free?

Yes. The application is free of charge (art. 13 of the CEIDG Act). Biznes.gov.pl mentions a stamp duty of PLN 17 only for the power of attorney of a representative not listed in CEIDG, e.g. when closing the business.

When can I issue my first invoice?

You may start the business on the day you file the application (art. 17 of the Entrepreneurs' Law), unless specific provisions say otherwise.

Do I need to go to ZUS separately when suspending?

Not for your own deregistration. ZUS does, however, ask you to deregister employees and registered family members before the suspension.
