Who can register a sole proprietorship?
EU and EEA citizens may generally conduct business in Poland on the same terms as Polish citizens.
For non-EU nationals, the answer depends on the residence document, citizenship and possible treaty rights. Certain residence permits, permanent residence, EU long-term resident status and other statutory grounds may provide access to sole proprietorship.
A visa or legal stay in Poland does not always give the holder the right to register in CEIDG. The specific legal basis should therefore be verified before the application is submitted.
What is needed for CEIDG registration?
Registration is made through CEIDG. The application may be submitted online or, depending on the circumstances, through a municipal office. Online registration requires an accepted electronic identification or signature method. A Polish Trusted Profile normally requires a PESEL number, while the technical compatibility of a foreign qualified electronic signature should be checked before relying on a fully remote procedure.
The entrepreneur provides personal and identification details, the business name, addresses, commencement date, PKD 2025 activity codes, the competent tax office, the selected income tax regime and information relevant to social insurance. The business name must include the entrepreneur's first name and surname, although an additional commercial name may be added.
Registration is free
CEIDG registration itself is free of charge. Unofficial letters requesting payment for entry in a commercial register should not be confused with official correspondence.
The CEIDG application transfers basic information to the tax and statistical authorities and the Social Insurance Institution. It does not replace every subsequent notification: separate VAT, social insurance, licensing or sector-specific filings may still be required.
Choosing the tax regime and VAT status
A sole proprietor may generally choose the progressive personal income tax scale, the 19% flat-rate income tax or a lump sum on recorded revenue, if available for the activity. Expected revenue, deductible costs, the type of services and the entrepreneur's personal situation should drive the choice.
Not every new entrepreneur must immediately become an active VAT taxpayer. In 2026, a domestic business may generally benefit from the small-business VAT exemption if annual sales do not exceed PLN 240,000, calculated proportionally when the business starts during the year. The exemption does not apply to every activity.
Providing services or selling goods across EU borders may require VAT-EU registration even where the entrepreneur otherwise benefits from the domestic VAT exemption.
Social security and health insurance
A sole proprietor is generally required to register for Polish social security and health insurance. Reliefs may be available to qualifying new entrepreneurs.
Cross-border situations require additional analysis. A person working in one EU or EEA country while operating a business in another may remain subject to the social security system of only one country under coordination rules.
KSeF and electronic communication
A new business should use accounting software that supports the Polish National e-Invoicing System, KSeF. By July 2026, mandatory KSeF already applies to most businesses.
The smallest taxpayers whose monthly invoiced sales do not exceed PLN 10,000 gross may use the transitional exemption from issuing invoices through KSeF until the end of 2026. Businesses should nevertheless be prepared to receive and process invoices issued through the system.
Personal liability remains the main risk
A sole proprietorship is not separate from its owner. The entrepreneur is personally responsible for contracts, taxes and business debts.
For low-risk service activity this may be acceptable. Where the business will employ staff, incur debt, handle substantial customer funds or assume significant contractual liability, a limited liability company may provide a more appropriate structure.
How the issue appears in practice
Hypothetical example: lawful stay does not always permit sole proprietorship
A non-EU national lawfully stays in Poland under a visa and agrees to start providing IT services to a client as a sole proprietor the following month. While preparing the CEIDG application, the founder learns that the visa alone does not provide the right to register a sole proprietorship. The planned engagement cannot begin or be invoiced through that model. Before accepting the commercial commitment, the founder should have verified the specific residence basis and the business rights attached to it, and then — depending on the outcome — registered a sole proprietorship, selected an available company structure or postponed the start date.
