Registering a company in Poland as a Sp. z oo for business and production is the best solution in 2026. Poland has become a key economic and logistics hub in Central Europe, as well as the primary home for millions of Ukrainians. The country combines a clear language, developed infrastructure, and easy access to the EU market.
Opening an account for a Sp. z o.o. / JDG company in Poland
Company account in Poland: bank, IBAN and payment system
After company registration, the next practical step is to open a working account. For a Sp. z o.o. or JDG, you can consider a local bank, a bank in another European country, or a European payment system / EMI, depending on where your clients and suppliers are located. For domestic settlements, an account in PLN can be used, while work with clients and suppliers across Europe can use EUR, IBAN and SEPA. International contracts can also be handled in USD when needed. It makes sense to select the account around your actual clients, suppliers and incoming and outgoing payment flows from the start. For an owner from Ukraine or Eastern Europe, this is especially convenient: the company is registered for specific business operations, not simply for an entry in a foreign register.
1. Special legal regime for Ukrainians
Thanks to the Special Act (Ustawa o pomocy obywatelom Ukrainy), Poland has created one of the simplest legalization systems for Ukrainian citizens:
PESEL UKR: It is issued under a simplified procedure and provides official protection status, the right to work without additional permits, and access to free healthcare (NFZ) and education.
Residence Card (Karta Pobytu): Ukrainians with UKR status can apply for a residence permit, either on the basis of employment or sole proprietorship, or under the special simplified CUKR procedure.
Social programs: Access to family benefits, for example the 800+ program for each child subject to enrollment in a Polish school.
2. Running a business: sole proprietorship and Spółka z o.o.
Unlike many other EU countries where foreigners are limited in their choice of business forms, Ukrainians with UKR status may register a sole proprietorship on the same terms as Polish citizens.
| Business form | Best suited for | Key features | Taxation |
|---|---|---|---|
| JDG (Jednoosobowa Działalność Gospodarcza) — sole proprietorship | Freelancers, IT specialists, services and small businesses. | Fast online registration through CEIDG. Full personal liability of the owner. | Ryczałt, a fixed turnover tax from 3% to 15% depending on the activity, or Skala podatkowa at 12%/32%. |
| Spółka z o.o. — limited liability company | Mid-sized businesses, trading companies and projects with several partners. | Minimum share capital — PLN 5,000. Liability is limited to the company capital. | Standard CIT — 19%, or the preferential 9% rate for small businesses with revenue up to ˆ2 million. Estonian CIT at 10%/20% is also available. |
3. Estonian CIT in Poland (CIT Estoński)
Poland has adapted the Estonian tax model. It is available to legal entities, including Spółka z o.o.:
0% income tax while funds remain inside the company and are used for its development.
Tax is paid only when dividends are distributed.
Rates: 10% for small businesses (Small Taxpayer) and 20% for others.
4. Why Poland is convenient for living and integration
Language barrier: Polish belongs to the Slavic language group, which makes it possible to reach a working B1–B2 level in 6–9 months.
Financial and logistics connectivity: A developed banking system (PKO, Pekao, mBank, Santander) with Ukrainian-language support in applications. Convenient transportation links with Ukraine, including Ukrzaliznytsia trains, bus routes and nearby airports in Rzeszów, Kraków and Warsaw.
Digital services (mObywatel): Government services, the TRUSTED profile (Profil Zaufany), tax returns and medical prescriptions are available on a smartphone.
The choice between a JDG on Ryczałt and a Spółka z o.o. in Poland depends on income level, cost structure, the number of partners and how you plan to withdraw profits.

1. JDG on Ryczałt — ideal for solo specialists and B2B
The Ryczałt od przychodów ewidencjonowanych tax is paid on total turnover (revenue) without deducting expenses.
Tax rates for IT and services:
12% — software development, programming and IT consulting.
8.5% — network administration, QA/testing, systems administration, web design, marketing and customer support.
Mandatory ZUS and Składka Zdrowotna contributions:
Social ZUS: First 6 months — ˆ0 (Ulga na start). Then 24 months — about PLN 450 (Mały ZUS). Full ZUS — about PLN 1,900/month.
Health contribution (Składka Zdrowotna): Linked to annual income, with three thresholds: up to PLN 60k, PLN 60k to PLN 300k, and above PLN 300k — from about PLN 450 to PLN 1,300/month.
Main advantage: All funds remaining after taxes and ZUS are your personal funds and can be spent immediately from your card.
Disadvantage: You are liable for sole-proprietorship debts with all of your personal assets.
2. Spółka z o.o. — for projects, agencies and work with investors
The company is a separate legal entity, so your personal assets are protected.
Profit taxation (CIT):
Standard CIT: 9% on profit for small businesses with annual revenue up to ˆ2 million.
Estonian CIT (CIT Estoński): 0% income tax while funds remain in the company account and are reinvested.
Withdrawing money personally (double taxation):
Dividend payments are subject to an additional 19% tax (PIT).
How to optimize: Paying compensation to a management board member (Powołanie), entering into a B2B contract with your own company, or receiving payments for intellectual property rights.
ZUS:
If a Spółka z o.o. has two or more shareholders, for example 90% and 10%, the company and shareholders do not pay ZUS merely because they own the company.
If there is only one shareholder, ZUS is paid at the full JDG level.
Comparative calculation (Example: IT contract of ˆ5,000 / about PLN 21,500 per month)
| Parameter | JDG (Ryczałt 12%) | Spółka z o.o. (CIT 9% + Dividends) |
|---|---|---|
| Monthly revenue | 21,500 PLN | 21,500 PLN |
| Business expenses | Not deducted | Assume PLN 3,500 (equipment, accountant, software) |
| Income/profit tax | ~PLN 2,580 (12% of 21.5k) | ~PLN 1,620 (9% CIT on net profit of 18k) |
| ZUS + Healthcare | ~PLN 2,500 (full ZUS + highest threshold) | PLN 0 (with 2+ shareholders) |
| Tax when dividends are distributed | PLN 0 (the money is immediately yours) | ~3,110 PLN (19% PIT) |
| Net cash to owner | ~16,420 PLN | ~PLN 13,270 (without withdrawal optimization) |
| Accounting | Simple (~PLN 300–500/month) | Full accounting (Pełna księgowość, ~PLN 800–1,500/month) |
Final conclusion
1. Choose a JDG on Ryczałt if you work as a solo contractor/freelancer (B2B), your main cost is your time, and your service code falls under the 8.5% or 12% rate. This provides strong net income with minimum bureaucracy.
2. Choose a Spółka z o.o. if you plan to launch an IT agency, hire staff, have business partners, your expenses exceed 30–40% of turnover, or limiting personal financial liability is important to you.
