Poland company setup (2026): B2B sole trader vs sp. z o.o. and tax options

Founders & Company Structures
, ,
1

For most solo founders, company setup in Poland comes down to two choices. One is a sole trader (JDG) invoicing clients “B2B” and taxed at the progressive scale, a 19% flat rate or a lump sum on revenue, which is 12% for many IT services. The other is a limited company (sp. z o.o.) with PLN 5,000 capital, 9% corporate tax for small taxpayers and 19% tax on dividends. Social contributions (ZUS) and the health contribution often decide which is cheaper.

Last checked: October 2026

In short:

  • A JDG on the 12% lump sum (ryczałt) is the classic B2B setup for IT contractors, but you pay tax on revenue with no deduction for costs, plus ZUS of PLN 1,926.76 a month at the full 2026 rate and a health contribution.
  • An sp. z o.o. costs PLN 5,000 in capital and about PLN 350 in court and gazette fees through the online S24 system, and pays 9% CIT if revenue was under €2 million; dividends then cost 19%.
  • Poland suits founders who actually live there: Polish tax residence follows a centre of interests test or more than 183 days a year.

Option 1: the JDG (sole trader) and its four tax options

A JDG (jednoosobowa działalność gospodarcza) is registered in the central business register, CEIDG. It is not a separate legal person, so you are personally liable for its debts.

PwC lists the tax options for an individual’s business income:

Tax form Rate Costs deductible? Notes
Progressive scale 12% up to PLN 120,000, 32% above Yes PLN 30,000 tax-free amount
Flat (liniowy) 19% Yes No tax-free amount
Lump sum on recorded revenue (ryczałt) Fixed rate by activity, up to 17% No Revenue limit of €2 million in the previous year
Tax card Closed to new users since 2022

A 4% solidarity levy applies to an individual’s income above PLN 1 million a year (PwC).

The lump-sum rates that matter for nomads

Tax firm MDDP sets out the main ryczałt rates:

Rate Typical activities
17% Some liberal professions: translators, lawyers, legal advisers, auditors, accountants, tax advisers, and others
15% Management consulting, financial services, advertising, market research and similar services
14% Healthcare, architecture, engineering and technical design
12% IT services such as software development, software consultancy and computer facilities management
8.5% Other services not listed at a higher rate

The 12% IT rate is why many developers in Poland work as B2B contractors. The rate applies to the gross invoice amount. If your costs are low, that can beat the 19% flat rate. If your costs are high, it usually does not.

Check which rate fits your activity code (PKD and the statistical service classification) before choosing. MDDP also warns that the lump sum is not available if you provide services to a current or former employer matching the work you did for them as an employee. Converting an employment contract into a B2B contract with the same company is the classic trap.

ZUS and the health contribution in 2026

Social contributions are where many simple comparisons go wrong. ZUS published the 2026 figures for self-employed people:

Scheme Monthly base Social contributions per month
Full (“duży ZUS”) PLN 5,652 (60% of projected average wage of PLN 9,420) PLN 1,926.76 including voluntary sickness insurance
Preferential PLN 1,441.80 (30% of the PLN 4,806 minimum wage) PLN 456.18 including sickness insurance
Mały ZUS Plus Between PLN 1,441.80 and PLN 5,652, based on prior-year income Varies

The full-rate total breaks down as pension PLN 1,103.27, disability PLN 452.16, sickness PLN 138.47, accident PLN 94.39 and Labour Fund PLN 138.47. Tax software firm iFirma describes the sequence for new businesses: a six-month “ulga na start” with no social contributions, then 24 months at the preferential rate. Mały ZUS Plus can then be used for 36 months within a 60-month period if you qualify. None of these reliefs cover the health contribution.

Health contribution (składka zdrowotna). This is separate from social ZUS and depends on your tax form (iFirma, Pitax):

Tax form Health contribution
Progressive scale 9% of income, minimum PLN 432.54 a month from February 2026
Flat 19% 4.9% of income, same minimum
Lump sum, revenue up to PLN 60,000 PLN 498.35 a month
Lump sum, revenue PLN 60,001-300,000 PLN 830.58 a month
Lump sum, revenue above PLN 300,000 PLN 1,495.04 a month

So a JDG on the lump sum earning more than PLN 300,000 a year pays about PLN 3,422 a month in ZUS and health contributions combined at the full rate. That is our sum of the published figures, before income tax.

Option 2: the sp. z o.o.

The sp. z o.o. (spółka z ograniczoną odpowiedzialnością) is Poland’s limited liability company.

Setting it up through S24. Accounting platform inFakt sets out the online route:

  • Minimum share capital: PLN 5,000.
  • Court registration fee: PLN 250, plus PLN 100 for the announcement in the court and commercial gazette (MSiG).
  • Tax on civil-law transactions (PCC): 0.5% of the capital, after deducting registration costs.
  • Every shareholder and representative must sign with a qualified electronic signature or a Polish Trusted Profile (Profil Zaufany).
  • The S24 articles are a fixed template. If you need custom articles or non-cash contributions such as IP, you use a notary instead.

Getsix, an accounting group serving foreign investors, says a foreign investor can often form an sp. z o.o. without being present in Poland. It adds that a non-EU national who physically runs the company from Poland needs a lawful basis of stay and may need work authorisation.

Corporate tax. PwC gives the CIT rates:

Rate Who pays it
19% Standard rate
9% Small taxpayers, whose sales revenue including VAT did not exceed the PLN equivalent of €2 million in the previous year, and new companies in their first tax year (unless formed by transformation or merger)

Dividends. PwC says dividends paid to individuals are taxed at a flat 19%. Dividends paid to non-residents face 19% withholding, reduced by treaties. Dividends to EU, EEA or Swiss companies holding at least 10% for two years can be exempt.

Distributed profit at the 9% rate therefore costs about 26.3% in total (9% plus 19% of the remaining 91%). At 19% CIT it is about 34.4%. PwC uses the same two figures.

ZUS still applies to a sole shareholder. Business advisory site Mikroporady says the only shareholder of a single-member sp. z o.o. is treated as self-employed for ZUS, at the full base, and cannot use the preferential rates. Get advice on the shareholder structure before you form the company.

Estonian CIT (ryczałt od dochodów spółek)

Poland also has an optional “Estonian CIT”, where the company pays tax only when it distributes profit. PwC gives the rates and conditions:

  • 10% for small taxpayers and new businesses, 20% for others.
  • Shareholders must be natural persons only.
  • The company must employ at least three people besides the shareholders, or meet an alternative salary-spend test.
  • Passive revenue must not exceed 50% of revenue.

PwC puts the combined rate on distributed profit at about 18% for small taxpayers and about 21% for others, after a special credit against the shareholder’s personal tax. The three-employee condition rules it out for most solo founders.

VAT

Poland’s standard VAT rate is 23%, with reduced rates of 8% and 5% (PwC). Crowe says the turnover limit for the small-business VAT exemption rose from PLN 200,000 to PLN 240,000 from 1 January 2026. If you invoice foreign business clients, place-of-supply rules often make the service reverse-charged, but you may still need to register. Check with an accountant.

JDG on 12% lump sum JDG on 19% flat sp. z o.o. at 9% CIT
Liability Unlimited Unlimited Limited
Tax on profit 12% of revenue 19% of profit 9% CIT, then 19% on dividends
Costs deductible No Yes Yes
Social ZUS Full, or start-up and preferential reliefs Same Sole shareholder pays full ZUS
Health contribution Fixed by revenue band 4.9% of income Applies to the sole shareholder
Setup CEIDG registration Same PLN 5,000 capital plus fees

Who can use this, and residence

Getsix says citizens of EU and EEA countries, Switzerland and the United States can generally do business in Poland on the same terms as Poles. Other nationals need a qualifying residence status. Law firm Dudkowiak describes a temporary residence permit for business activity, with conditions that include either employing at least two people full-time or meeting income tests.

Taxes follow residence. PwC says you are Polish tax resident if your centre of personal or business interests is in Poland, or you spend more than 183 days there in a tax year. A JDG or sp. z o.o. makes most sense if you are a Polish tax resident. If you live elsewhere, your home country will usually tax your JDG income, and it may treat a Polish company you run from abroad as its own. Our guide on the 183-day rule explains why.

Non-EU founders should also watch the Schengen 90/180 limit while their permit is processed.

Pitfalls

  • Comparing only income tax. At low incomes the fixed ZUS and health payments dominate.
  • The former-employer rule. Lump sum and flat tax may be blocked if you invoice your old employer for the same work.
  • Wrong activity code. The 12% IT rate covers specific services. Some “IT-adjacent” work, such as some consulting or marketing, falls under 15% or 8.5%.
  • The sole-shareholder ZUS trap. A one-person sp. z o.o. does not escape full ZUS.
  • Estonian CIT conditions. Miss the employee test and you lose the regime.
  • Forms by deadline. Pitax notes that the deadline to change your tax form for 2026 was 20 February 2026.

Quick answers

Q: What is the 12% lump sum for IT in Poland?
It is a ryczałt rate on revenue for certain IT services, such as software development and consultancy, for sole traders. You pay 12% of invoiced revenue with no deduction for costs, plus ZUS and a health contribution fixed by revenue band, from PLN 498.35 to PLN 1,495.04 a month in 2026.

Q: How much does it cost to set up an sp. z o.o. in Poland?
Through the S24 online system you need PLN 5,000 of share capital, a PLN 250 court fee and PLN 100 for the gazette announcement, plus 0.5% PCC tax on capital. Signing needs a qualified e-signature or a Polish Trusted Profile. A notary route costs more but allows custom articles.

Q: Is a sp. z o.o. cheaper than B2B self-employment?
Not always. A small company pays 9% CIT and 19% on dividends, about 26.3% combined. A sole shareholder still pays full ZUS. A JDG on the 12% IT lump sum often costs less for high-revenue, low-cost contractors. Model both with an accountant using your real figures.
