How to start a business in Poland — 2026

Poland has one of Central Europe's largest domestic markets and a mature, fully digital company registry — so for many founders it is one of the easier EU countries to start in. The two routes that matter for most small businesses are a sole proprietorship (registered free through CEIDG) and a limited liability company, the spółka z ograniczoną odpowiedzialnością or sp. z o.o., which you can now set up online in a day or two. This guide covers both, plus the tax and VAT rules you need to plan for in 2026.

This is general information, not legal or tax advice — rules vary by country and change; confirm with a qualified professional before acting.

Sole proprietorship (JDG) via CEIDG

The simplest legal form is jednoosobowa działalność gospodarcza (JDG) — a sole proprietorship. You register it for free in the CEIDG (Central Registration and Information on Business) by completing the CEIDG-1 form on the government portal biznes.gov.pl, signing it with a profil zaufany (trusted profile) or a qualified electronic signature. The entry is made no later than the next business day after submission.

A JDG gives you a single registration that covers your tax (NIP) and statistical (REGON) numbers. The trade-off, as with sole traders everywhere, is that there is no separation between you and the business — you are personally liable for its debts.

You also need to register with the social security institution, ZUS, which you can do during the CEIDG process or within seven days of starting activity.

How a JDG is taxed

A sole proprietor chooses one of three personal income tax regimes:

• Progressive scale — 12% up to PLN 120,000 of income and 32% above it, with a PLN 30,000 tax-free allowance.
• Flat tax — a flat 19% on business income.
• Lump sum on registered revenue (ryczałt) — rates from 2% to 17% depending on the type of activity, charged on revenue rather than profit.

The right choice depends heavily on your margins and costs, so it is worth modelling before you register.

Limited liability company (sp. z o.o.)

If you want limited liability, outside investors, or a more credible structure for larger contracts, the sp. z o.o. is the standard vehicle. Key facts:

• Minimum share capital is PLN 5,000 (roughly €1,150). Each share must have a nominal value of at least PLN 50 — so the common set-up is 100 shares of PLN 50.
• The full capital must be covered by the time of registration.
• Shareholders' liability is limited to the company; they are not personally liable for its debts.

The company itself is registered in the KRS (National Court Register), and modern registration issues the KRS, NIP and REGON numbers in a single automated flow.

Online registration through S24

You do not need a notary for a standard company. The S24 system lets you register an sp. z o.o. online using a template deed of association, signed with a profil zaufany or a qualified electronic signature. With documents correctly prepared, registration typically completes in about one to three business days — considerably faster and cheaper than the traditional notarial route.

The S24 route uses a fixed template, so if you need bespoke articles (unusual share classes, contributions in kind, tailored governance), you will still want the notarial path. For most first companies, the template is fine.

Corporate tax: 9% or 19%

An sp. z o.o. pays corporate income tax (CIT). The standard rate is 19%, but a reduced 9% rate applies to small and newly established companies on income other than capital gains.

To use the 9% rate in 2026 you generally need "small taxpayer" status (based on the previous year's sales, including VAT, up to PLN 8,517,000) and your current-year revenue must stay under PLN 8,431,000 (about €2 million, excluding VAT). Cross that current-year limit and you switch to 19% on cumulative income from the start of the tax year.

Bear in mind that profits distributed as dividends are taxed again at the shareholder level — the classic double-taxation of a company structure, which is one reason many small operators start as a JDG. If you are still weighing the company-versus-sole-trader question generally, our overview of how to start an online business in Europe walks through the decision, and it is worth comparing Poland with a fully digital alternative like starting a business in Estonia.

VAT

The standard Polish VAT rate is 23%, with reduced rates of 8%, 5% and 0% for specific goods and services.

You must register for VAT once your taxable turnover exceeds the small-business threshold. From 1 January 2026 that threshold rises to PLN 240,000 (about €56,000), up from PLN 200,000 — part of the package accompanying Poland's e-invoicing reform. Below it, registration is optional; many B2B businesses register voluntarily to reclaim input VAT. If you sell across the EU and need to work backwards from a gross price, our EU VAT calculator handles the maths.

E-invoicing (KSeF) is now mandatory

Poland's national e-invoicing system, KSeF, became mandatory in 2026. Large taxpayers (2024 turnover over PLN 200 million) had to start issuing structured e-invoices from 1 February 2026, and all other established taxpayers from 1 April 2026; the smallest micro-enterprises follow on 1 January 2027. In practice this means B2B invoices must be sent through KSeF in a structured XML format and are only treated as issued once the system validates them and assigns a KSeF ID. Factor this into your accounting software choice from day one.

Rough cost summary

• JDG: free to register via CEIDG; main ongoing cost is ZUS social contributions plus your chosen income tax.
• sp. z o.o.: PLN 5,000 minimum capital (which stays in the business), modest S24 registration fees, plus accounting — a company must keep full books, so budget for a bookkeeper or accounting software.
