JDG or sp. z o.o. in Poland: which should you choose?

For most freelancers in Poland a JDG (sole trader) is cheaper and simpler than a sp. z o.o. (limited company), and it stays that way even at high incomes if you take all the profit home. A company is worth its extra cost when you leave profit in the business, share it with partners, or want business debts kept away from your own assets. For some foreigners it is the only option.

All amounts are for 2026. ZUS is the Social Insurance Institution.

JDG and sp. z o.o. side by side

A JDG, jednoosobowa działalność gospodarcza (one-person business activity), is you, registered as a business in CEIDG, the public register of sole traders. A sp. z o.o., spółka z ograniczoną odpowiedzialnością (limited liability company), is a separate legal person registered in KRS, the National Court Register.

VAT and KSeF, the national e-invoicing system, work the same way for both, including the 240,000 PLN a year VAT exemption limit.

What a company costs before it earns anything

The biggest surprise is ZUS. The only shareholder of a sp. z o.o. is treated like a self-employed person, even without working for the company or taking money out. In 2026 that is 1,926.76 PLN of social contributions and 830.58 PLN of health contribution: about 2,757 PLN a month, from the first month.

The start-up reliefs do not apply. Ulga na start (6 months without social ZUS), the 24 months of preferential ZUS and Mały ZUS Plus (lower ZUS on a low income) are only for people running a business in their own name. ZUS for a sp. z o.o. owner explains the details.

One exception: if you also have a job elsewhere paying at least the minimum wage (4,806 PLN in 2026), pension and disability contributions come from the job. You then pay mainly the 830.58 PLN health contribution.

Watch out: the rule covers only a sole shareholder, so in a company with two shareholders it does not apply. Whether ZUS or a court would accept a token 1% partner is not settled: ask an accountant or ZUS before you rely on it.

Every sp. z o.o. keeps full accounting books, whatever its size. Online accounting offices list prices from about 620–650 PLN a month for a small company (September 2026).

Each year the financial statements are signed by 31 March, approved by 30 June and filed in KRS within 15 days of approval. After registration you also report the company’s beneficial owners to CRBR, the register of beneficial owners, within 14 days.

Taxes: where a company wins and where it loses

A company’s profit is taxed twice: first corporate income tax (CIT) in the company, then 19% personal income tax (PIT) when it is paid to you as a dividend.

The 9% rate needs revenue in the year of no more than 2 million EUR (8,431,000 PLN in 2026) and, after the first year, small-taxpayer status. A company created by transforming a JDG, or one into which you contribute your existing business worth over 10,000 EUR, cannot use 9% in its first two years.

Example: 300,000 PLN profit in 2026, all of it taken home, full ZUS with sickness insurance on both sides, before the company’s higher accounting bill.

If you take everything out as dividends, the combined 26.29% is higher than the flat tax’s 19% plus 4.9%, and the company’s ZUS is no lower. On our 2026 arithmetic the JDG stays ahead until profit reaches several million złoty a year. At that point the 4% solidarity levy on JDG income above 1,000,000 PLN tips the balance, because dividends do not pay it.

The company pulls ahead on money you leave in it for equipment, staff or a cushion, which has so far paid only 9%.

Estonian CIT (ryczałt od dochodów spółek) changes the picture. The company pays no CIT while profit stays in. On a payout the total is about 20% for a small company, or 25% otherwise. It is only for companies owned by individuals, and it comes with an employment condition that new companies meet gradually. See Estonian CIT. A government bill of 22 September 2026 would change these rules from 2027; it is not law yet.

For a JDG, the tax form matters as much as the legal form: a programmer on 12% ryczałt may pay less than either option above. See choosing your tax form.

How you take money out

In a JDG the business’s money is yours. Tax is charged on the profit, and moving money to your private account changes nothing.

In a company, money needs a legal basis each time:

• Dividend: after the yearly statements are approved and the shareholders vote to share the profit. An interim dividend is possible only if the articles of association allow it and the last approved statements show a profit.
• Pay for sitting on the board, set by resolution: taxed on the tax scale, no social ZUS, 9% health contribution.
• An invoice from your own JDG to the company, at a market price.
• An employment contract: courts have questioned whether a sole shareholder can really be employed, so be careful.

If you are the sole shareholder and the only board member, even a loan from the company to you needs a notarial deed (unless made with an S24 template).

How limited is “limited liability”?

In a JDG you answer for business debts with everything you own, and property shared with a spouse can also be affected.

In a sp. z o.o., shareholders risk only what they put in. Board members are a different story. If a bailiff cannot recover a debt from the company, board members become personally liable. They escape only if they can show, for example, that they filed for bankruptcy within 30 days of the company becoming insolvent. The same applies to the company’s unpaid taxes and ZUS.

In a one-person company you are usually the board too, so act in time.

Which one can a foreigner or a Ukrainian open?

• EU, EEA and Swiss citizens can open either, on the same terms as Poles.
• Other foreigners can open a JDG only with one of the statuses the law lists, such as permanent residence, EU long-term residence, certain temporary residence permits (EU Blue Card, studies, family reunification), refugee status, temporary protection or a valid Karta Polaka (Pole’s Card). A work permit or a residence-and-work permit is not enough. See how a foreigner opens a JDG.
• Everyone else can do business only through a company. Any foreigner may set up or own a sp. z o.o., even one who lives abroad with no Polish permit.
• Ukrainians with temporary protection (PESEL status UKR) or a CUKR residence card (the card for former temporary-protection holders) can open a JDG on Polish terms. See starting a business as a Ukrainian.

For foreigners: from 1 November 2026 a foreigner registering a JDG in CEIDG needs a PESEL (Polish ID number) or an EU cross-border eID identifier. A sp. z o.o. needs no PESEL: KRS records a date of birth instead, and you sign in S24 with a qualified electronic signature or go to a notary. A non-EU board member working from Poland for more than 6 months in any 12 needs a work permit or free access to the labour market.

Can you switch later?

Yes, and starting with a JDG is the cheaper path.

JDG to company. You can transform the JDG: a notarial plan, an audit of the plan by an auditor the court appoints (up to 2 months), then registration in KRS. The company takes over your contracts and most permits. You stay jointly liable for the old JDG debts for 3 years, and the 9% CIT rate is closed for the first two years (Estonian CIT is not).

The other route is a new company in S24 while you suspend or close the JDG. It is faster, but contracts do not move by themselves. See moving from a JDG to a sp. z o.o..

Closing. A JDG closes with one free form. A solvent company needs a liquidation: a notice to creditors, at least 6 months before anything is shared out, and 300 PLN to strike it off KRS.

What to do next

1. If you work alone and can open one, start with a JDG and pick the tax form that suits your income.
2. Consider a sp. z o.o. if you will reinvest much of the profit, bring in partners, take risks you want kept away from your home, or cannot open a JDG.
3. Before you decide, ask an accountant to run both options with your own revenue, costs and plans. The 2027 ZUS amounts for a sole shareholder are not published yet; the minimum wage rises to 4,950 PLN on 1 January 2027.
4. Whichever you choose, keep every invoice and bank statement by month. Komplet, our free Mac app, files each document into the right month and prepares a folder for your accountant.
