Poland is a good place to work for yourself. Registering a sole proprietorship is free and fast, and the tax menu is wide. It is also a country where the rules for business have changed several times recently, with new deadlines this autumn. Here is what applies if you start a business in Poland now.
How do you register a sole proprietorship?
The sole proprietorship (jednoosobowa działalność gospodarcza, JDG) is registered in the central register CEIDG. Registration is free. One form (CEIDG-1) gives you the tax number (NIP) and statistical number (REGON) and, on biznes.gov.pl, can also register you with ZUS and for VAT. You may start on the day you file, and the entry is made at the latest the next working day.
You prepare your business name (at least your first and last name), address, activity codes (PKD), tax regime and VAT status. Since 1 October 2026 every entrepreneur must also have an electronic delivery address (e-Doręczenia): it is created during registration, and you activate it with the link you receive by email.
What changes on 1 November 2026?
According to biznes.gov.pl, a first CEIDG registration becomes online-only from 1 November 2026, and a foreigner needs a PESEL, or failing that a cross-border identifier issued by an EU state. Until 31 October 2026 you can still file at the town hall with your ID. After that date, a paper application for a first registration is not processed; you use biznes.gov.pl, the mObywatel app or online banking. Changes, suspensions and closures remain possible on paper until 31 October 2028.
Online filing means logging in through login.gov.pl and signing with a trusted profile, a qualified signature or an e-ID card. A proxy cannot file online. So get your PESEL first; see PESEL number in Poland and Poland e-government for expats.
Which tax regime, which activity code and which VAT status fit you is not obvious, and a wrong choice is expensive to fix. Moovy, our AI assistant, can walk through your case and list the options and their trade-offs. You file and sign yourself.
Which tax regime should you choose to start a business in Poland?
Three exist for a sole proprietor, and you declare your choice in the CEIDG form (otherwise the scale applies):
- Scale: 12% then 32% on profit; joint taxation with a spouse and the child credit are possible; health contribution 9% of income, at least 432.54 zloty a month (February 2026 to January 2027).
- Linear: flat 19% of profit, with no tax-free amount; health contribution 4.9%, same minimum.
- Lump sum (ryczałt): 2% to 17% of revenue depending on the activity, with no deduction of costs. Several IT services (software publishing, IT and software consulting, among others) are at 12%; 8.5% applies to many other services and is the default rate if you have mixed activities without separate records. Open if last year's revenue did not exceed 2 million euros (8,517,200 zloty for 2026).
Lump-sum health contributions are in brackets: 498.35, 830.58 or 1,495.04 zloty a month in 2026. The exact lump-sum rate depends on your activity code, so have it confirmed. See ZUS contributions for the self-employed in Poland.
Be careful if you plan to work for your current or former employer: selling them services in the same field as your job closes the linear tax (for the current year) and the lump sum (current or previous year). Only the scale then remains.
What about VAT and KSeF invoices?
You can stay outside VAT while sales stay under 240,000 zloty a year (2026), except for activities such as consulting or legal services, which charge VAT from the first zloty. The VAT-R form registers you, at the latest before your first taxable sale.
Invoices go through the national e-invoicing system KSeF: compulsory since 1 February 2026 for the largest companies and since 1 April 2026 for the others. Until 31 December 2026, businesses with invoices up to 10,000 zloty a month (VAT included) can still issue them outside KSeF, and the tolerance ends on 1 January 2027. On 16 September 2026 the Ministry proposed to extend the postponement of penalties for KSeF mistakes to the end of 2027; this needs a change in the law, and the duty to use KSeF stays. The Ministry offers free tools: the KSeF web and mobile applications.
VAT returns use JPK_V7M (monthly) or JPK_V7K (quarterly), sent by the 25th of the following month, even if they are nil.
Can you work without registering?
Yes, if your revenue stays under 225% of the minimum wage per quarter (10,813.50 zloty in 2026; the limit has been quarterly since 1 January 2026) and you had no business in the past 60 months. You pay no ZUS contributions for it, keep a simplified sales register, issue an invoice if the client asks, and declare the income in your annual return at the scale. Once you exceed the limit, you have seven days to register in CEIDG. Since 1 June 2025, foreigners other than EU, EEA, Swiss and US citizens can use this option only if they meet the conditions to run a business in Poland.
How do you start a business in Poland step by step?
- Get your PESEL. For a foreigner it is required from 1 November 2026 (or an EU cross-border identifier); see PESEL number in Poland.
- Create your digital identity, such as the trusted profile, to sign online.
- Prepare your choices: name, address, PKD activity codes, tax regime, VAT status.
- File the CEIDG-1 on biznes.gov.pl, in mObywatel, or through a bank or accounting office that offers it (registration only). The mObywatel app does not handle VAT or ZUS registration.
- Tick the ZUS and VAT boxes on biznes.gov.pl to save time.
- Receive your entry, at the latest the next working day, and activate your e-Doręczenia address.
- Register with ZUS within seven days if you did not do it in the form.
- Open a business account. If you are a VAT payer, clients check your account on the white list (biała lista) before paying.
Keep at hand your passport or identity card, your PESEL, a digital identity to sign online, and the title to the addresses you declare.
How do you keep the books, and which returns follow?
At the scale or linear tax, you keep a revenue and expense ledger (PKPiR). At the lump sum, a revenue register (ewidencja przychodów). The ledgers must be kept electronically in 2026 if you send a monthly JPK_V7M, and from 2027 for everyone; the 2026 ledger is sent to the tax office after year end, by 30 April. Full accounting becomes compulsory above 2.5 million euros of revenue (10,646,500 zloty for 2026). You can keep the books yourself or entrust them to an accounting office.
Tax advances are paid monthly (or quarterly if you qualify), then the annual return is filed between 15 February and 30 April: PIT-36 at the scale, PIT-36L at the linear tax, PIT-28 at the lump sum. The bigger picture of income tax in Poland is in income tax in Poland for new residents.
When is a limited company better?
A sole proprietor answers for business debts with all personal assets. A limited company (sp. z o.o.) is a separate legal person: the company answers for its debts, the shareholders up to their contributions, and managers can be liable if enforcement against the company fails. It needs capital of at least 5,000 zloty and registration in the KRS, simplest online through S24: 250 zloty in court fees plus 100 zloty for publication, or 500 zloty with a notary plus the notary's fees.
The company pays corporate income tax at 9% if it is a small taxpayer or in its first year (with exceptions), otherwise 19%, and dividends you pay yourself are taxed at 19%. Full accounting is compulsory, so an accountant is practically needed. A sole shareholder pays ZUS contributions like a self-employed person, unless already covered in another country. Non-EU citizens can also set up a sp. z o.o.
Are there special points for EU, British and other founders?
EU, EEA and Swiss citizens have the same rights as Poles. If you work in Poland, Polish social security applies; if you also work elsewhere, ask for an A1 certificate. British citizens covered by the Withdrawal Agreement keep EU-citizen rights, while others can run a sole proprietorship only with a residence status that allows it; see moving to Poland from the UK. Health cover comes through your ZUS registration; see healthcare in Poland for expats.
What are the common mistakes?
- Missing the 1 November change and arriving at the town hall with a paper form.
- Comparing only tax rates and not the health contribution.
- Wrong lump-sum rate for your activity: a wrong one can be expensive in an inspection.
- Working for your former employer in the same field, which excludes linear and lump-sum taxation.
- Believing a sole proprietorship shields you. It does not; only a company separates your assets from the business.
Before you start a business in Poland and choose your regime, your VAT status or your legal form, have your plan confirmed by a Polish accountant (księgowy) or tax adviser. It is the cheapest moment to get it right. Rules change; check biznes.gov.pl.
