Registering a jednoosobowa działalność gospodarcza — a JDG, Poland’s sole proprietorship — is free, online, and takes an afternoon. There is no capital requirement, no notary, no office lease and no Polish partner. The company-formation services advertising against this search are selling you the easy half.
The hard half is the two hours before and the seven days after: whether your residence title permits you to run a business here at all, and registering with ZUS once you have. Get those wrong and the free afternoon becomes the expensive part.
Checked on 7 September 2026.
Before anything: the eligibility check
Do this first. Not as due diligence — as a gate.
Your residence title decides whether you may register a JDG. The rules are in the Act on the rules of participation of foreign entrepreneurs in economic activity in Poland, which lists the titles that let a foreign national trade on the same terms as a Polish citizen. Permanent residence and the EU long-term resident permit are on that list. So is a specific set of temporary residence permits, granted for particular reasons.
The temporary residence and work permit — the single permit — is commonly not among them. That is the trap this whole post exists for, and it catches people who did everything else correctly. CEIDG will not stop you: the register does not adjudicate your immigration status, so a registration that your permit does not support can complete without a single error message and sit there, visible, until someone at Mazowieckie reads your file.
So:
- Take out your residence decision, not the card. The legal basis is on the decision.
- Check that basis against the statute’s list.
- If it is not unambiguously there, pay a lawyer for one hour before you register. This is the cheapest hour in the entire process.
If you are still deciding which permit to hold, the permit class is chosen once, at the start, and this is one of the consequences of that choice.
What you actually need
Assuming the gate is open, four things. Two of them you probably already have.
A PESEL. Your Polish identification number. You can register a business without one in some circumstances, but every part of the process afterwards — the tax office, ZUS, e-filing, the bank — assumes it, and doing this without one is choosing the hard path for no gain.
A profil zaufany or a qualified e-signature. The profil zaufany is Poland’s free trusted profile, the login that signs official filings, and it is what you will use to submit the registration. Most banks operating here can confirm one for their customers online; failing that it is confirmed in person at a punkt potwierdzający. Set this up before you sit down to register, because doing it mid-form is where an afternoon becomes two.
An address for the business. A Polish address you are entitled to use. This is the one that surprises people who have not signed a lease yet, and it connects to the lease problem the rest of this site covers — the address on your business registration and the address on your meldunek are separate questions, but both need somewhere real.
A view on your tax regime and your PKD codes. PKD is the Polish classification of business activity, and you select the codes that describe what you do. The codes matter more than they look — on the ryczałt the rate applied to your revenue follows from what your activity actually is, and the codes are the first thing anyone reads to work that out. If you are heading for the lump-sum regime, read the *ryczałt* arithmetic before you pick, not after.
What you do not need
- A lawyer, for the registration itself. The form is the form. Save the lawyer for the eligibility question above, which is a genuinely hard reading of a statute.
- A company registration service. They fill in a free government form on your behalf. Where they add value is the accounting relationship, and you can buy that directly.
- Share capital. A JDG has none. You are not forming a company; you are registering yourself as a trader.
- An office. A registered address is not a leased office.
- A Polish co-signer, partner or director. None of these exist in a JDG. If someone has told you otherwise, they are describing a spółka z o.o., which is a different instrument with a different cost base.
- VAT registration, necessarily. Whether you must register depends on what you sell and to whom, and the answer changes the moment a client is outside Poland — invoicing a foreign client from a Warsaw JDG covers that specifically.
The registration, in order
The form is CEIDG-1, filed through the CEIDG service on biznes.gov.pl. It is free. There is no fee to register a JDG and anyone charging you a government fee for it is charging you their fee.
- Sign in with your profil zaufany.
- Enter your identification details and your business address.
- Select your PKD codes — a main code and as many secondary ones as genuinely apply.
- Give your start date. This is a real decision, not a formality: it starts the clock on everything in the next section. Do not backdate it and do not set it to tomorrow because the form is in front of you today.
- Choose your form of taxation — the scale, podatek liniowy, or the ryczałt.
- Nominate your bank account and your tax office.
- Submit.
The registration propagates to the tax office, the statistical office and ZUS from the single filing. That consolidation is the genuinely good part of the Polish system and it is why this is an afternoon rather than a week.
On the tax regime: it is a choice, not a permanent one, but the window to change it is tied to your first revenue of the year rather than to the annual filing deadline — so it is early, and it is easy to miss by assuming it runs to April. Ask your księgowa for this year’s exact date before you rely on being able to switch.
The seven days after
Registering with CEIDG does not register you with ZUS as a contributor. The business exists; your insurance does not. You have seven days from the start date to file the ZUS declaration, and which form depends on what you are claiming:
- ZUS ZZA — health contribution only. This is what you file if you are on ulga na start, the relief that removes social contributions for the first six full months.
- ZUS ZUA — social and health contributions. This is what you file when the social contributions apply.
This is the single most common administrative miss in the whole process, because CEIDG’s confirmation email reads like completion. It is not. The ZUS ladder — *ulga na start*, preferential, full sets out what each stage costs in 2026 and, more usefully, what each of those totals actually contains.
The health contribution is separate from the social ones and it is never waived. Even on ulga na start you pay it — that is exactly why the form is ZZA rather than ZUA. A reading of the relief as “no ZUS for six months” is wrong in the direction that costs you NFZ cover.
What this costs
The registration: nothing.
The first month, realistically: the health contribution, which on the ryczałt is banded and starts at 498.35 zł monthly for revenue under 60,000 zł on 2026 figures published by gofin and Symfonia, derived from the average enterprise-sector wage for Q4 2025 of 9,228.64 zł. Plus a księgowa, whose fee is a market rate rather than a published one — get two quotes and expect the cheaper to be a filing service and the dearer to be someone who answers questions.
The steady state, once the relief runs out: full ZUS at 1,926.76 zł a month on the Firmove and poradnikprzedsiebiorcy figures, including voluntary sickness cover and Fundusz Pracy. State those components whenever you quote that number — other sources publish roughly 1,575 zł and roughly 1,600 zł for 2026 counting differently, and comparing two of these totals without knowing what is inside them produces a conclusion about nothing.
Where this post is uncertain
The registration mechanics above are stable and the CEIDG service documents them itself. The eligibility rules for a foreign national are summarised from the statute named at the top, and the statute is the authority — not this post, and not the eligibility page published by a company that sells registrations. The 2026 contribution figures are dated and attributed and they reset each January and February. Whether your particular permit, in your particular case, supports a JDG is a question for a lawyer reading your decision or for the office holding your file, and it is the one question here where a general answer is worse than none.
