Register a Company in Poland EU Company, Low Costs

A Polish sp. z o.o. can be registered online in days for PLN 350 in fees, pays 9% corporate tax while small, and opens a residence route for its owner. Americans can also simply register a sole proprietorship under a 1990 treaty.

In short

The usual company is the sp. z o.o. (limited liability company): PLN 5,000 minimum capital, registered online through S24 for PLN 350 in court and publication fees — often in about 3 working days, without a notary — or by notarial deed for custom articles (PLN 600 in fees plus the notary). A PSA needs only PLN 1 of capital. Corporate tax is 19%, or 9% for small taxpayers with revenue up to €2 million; Estonian CIT taxes only distributed profit at 10% or 20% but requires individual shareholders. Dividends to US shareholders carry 15% withholding (5% for a US company with 10%+). VAT is 23%, with an exemption up to PLN 240,000 from 2026, and KSeF e-invoicing is mandatory from April 2026. Beneficial owners go to the CRBR within 14 days. US owners usually file Form 5471; a sp. z o.o. can elect to be disregarded, an S.A. cannot.

Not American?

Canadians, Australians, Brits and other non-EU citizens: the same rules apply

Polish company law is the same for every foreign founder. A few points differ for Americans:

  • Canada
  • Australia
  • New Zealand
  • United Kingdom
  • Japan
  • South Korea
  • + other visa-free countries
Sole proprietorshipUS citizens can register one like Poles under the 1990 treaty; most other non-EU citizens need a permit first.
Living in PolandA company does not give you residence by itself — you need a residence permit for business, which has an income or hiring test.
Tax treatyThe 1974 US–Poland treaty cuts dividend withholding from 19% to 15%, or 5% for US companies with 10%+.

Why Poland

Why Americans Register Companies in Poland

Poland offers fast online registration, a 9% rate for small companies, a 5% IP Box and lump-sum taxes for freelancers, plus a large, lower-cost workforce inside the EU. A US–Poland treaty lets Americans run a sole proprietorship like Poles.

The trade-offs: paperwork in Polish, mandatory e-invoicing since 2026, monthly VAT and accounting files, and residence permits that can take a year in the big cities.

Corporate Tax

Poland's Corporate Tax — Standard, Small and Estonian Model

The standard rate is 19%. Small taxpayers — revenue up to €2 million (PLN 8,517,000 for 2026) in the previous and current year — pay 9% on operating income, but not on capital gains. Estonian CIT defers tax until profits are distributed (10% for small and new companies, 20% for others); it requires individual shareholders only, at least 3 employees and limited passive income. The IP Box taxes qualifying IP income at 5%, and R&D relief adds a 200% deduction for R&D staff costs.

Step by Step

How to Register a Company in Poland

  1. Plan the structure

    Sp. z o.o., PSA or sole proprietorship — and US classification (Form 8832) before you start.

  2. Get a qualified e-signature

    Non-residents can sign S24 documents online with one; a representative is common but not required.

  3. File through S24 or a notary

    S24 with standard articles costs PLN 350 in fees and often takes about 3 working days; the notarial route costs PLN 600 in fees plus the notary and takes 2–8 weeks.

  4. Pay in the capital

    For S24 companies within 7 days of registration.

  5. Tax numbers and VAT

    NIP and REGON are assigned automatically; file the VAT-R registration separately.

  6. Beneficial owners and bank

    Report owners to the CRBR within 14 days and open a business account (Polish banks ask US citizens for a W-9).

  • Beneficial owners

    Owners of more than 25% are reported to the CRBR within 14 days; the register is still public. A draft law would limit public access from 2027.

  • Social security

    Sole traders pay reduced ZUS for their first 30 months.

Expert Notes

What Americans Should Know Before Registering in Poland

  • Watch the 9% rate and NCTI

    A Polish company taxed at 9% falls below the US high-tax threshold — get US advice before choosing.

  • Estonian CIT is not for LLC-owned companies

    It needs individual shareholders, so holding through a US LLC rules it out.

  • Budget for accounting

    Full accounting, monthly VAT files and KSeF mean you need a Polish accounting office.

  • A company does not give you residence

    The residence permit for business needs an income or hiring test — or use the treaty sole proprietorship plus a permit.

Registering a Polish company is right for you if…

  • You want a low-cost EU company with fast online registration.
  • You can work with a Polish accounting office.
  • You have US tax advice on Form 5471, NCTI and check-the-box.
  • You have a residence plan if you will live in Poland.

We work with Polish lawyers, notaries and accounting offices who set up companies for American founders and coordinate with US tax advisers.
