JDG vs Sp. z o.o. vs Sp. k. in Poland — Which Company Type for IT Freelancers?

When going self-employed in Poland, you have several business structure options. The three most relevant for IT freelancers and contractors are:

• JDG — Jednoosobowa Działalność Gospodarcza (sole proprietorship)
• Sp. z o.o. — Spółka z ograniczoną odpowiedzialnością (limited liability company, equivalent to UK Ltd or German GmbH)
• Sp. k. — Spółka komandytowa (limited partnership)

For the vast majority of IT freelancers in Poland, the answer is: start with JDG. But knowing when and why to consider the others is important as your business grows.

Quick Comparison Table

JDG — Sole Proprietorship

How It Works

You and your business are the same legal entity. Income from the business is your personal income, taxed directly under PIT (Personal Income Tax).

Taxes

• Ryczałt 12%: Applied to gross revenue. No deduction of costs. Best for IT services with low expenses.
• Podatek liniowy 19%: Applied to profit (revenue minus costs). Better if you have significant business expenses.
• Health insurance: Tied to revenue or income depending on tax form.

ZUS Contributions

Full ZUS applies, with the start relief and small ZUS phases reducing burden in early years (see ZUS Social Security guide).

Liability

You are personally liable for all business debts. Your personal assets (bank accounts, property) can be seized to satisfy business obligations.

Best For

• IT freelancers billing 10,000–500,000 PLN/year
• Single-person operations
• Those who want minimal admin overhead
• Anyone in the first 3–5 years of self-employment

Sp. z o.o. — Limited Liability Company

How It Works

A separate legal entity owned by shareholders. You can be the sole shareholder and director. The company pays its own taxes (CIT), and you pay PIT on salary or dividends extracted from it.

Taxes — The Double Taxation Challenge

The traditional sp. z o.o. structure involves double taxation:

1. Company pays CIT: 9% (for companies with revenue under 2M EUR) or 19% on profit
2. Owner pays PIT on dividends: 19% — no ZUS on dividends, but no deductions either

Effective rate example (9% CIT + 19% dividend PIT):

• 100,000 PLN company profit
• CIT: 9,000 PLN → 91,000 PLN remains
• Dividend: 91,000 PLN × 19% = 17,290 PLN
• Net to owner: 73,710 PLN (73.7%)

Compare to JDG ryczałt 12%: 100,000 PLN revenue → effective ~17–20% total burden → net ~80,000 PLN+

Estonian CIT (Estoński CIT)

Since 2022, Polish sp. z o.o. can opt for Estonian CIT — no corporate tax is paid until profits are distributed. If you reinvest profits in the business, CIT is deferred indefinitely.

For IT companies reinvesting in growth, Estonian CIT can be compelling. For solo contractors who extract all income monthly, the benefit is minimal.

ZUS for Sp. z o.o. Owners

If you work as an employee of your own sp. z o.o., standard employee ZUS applies. If you're a shareholder-only without employment, there are complex rules — many multi-shareholder setups use this to reduce ZUS.

Accounting Cost

Sp. z o.o. requires full commercial accounting (pełna księgowość), plus annual financial statements, company registration fees, and potentially an auditor above certain thresholds. Budget 400–800 PLN/month minimum for accounting.

Best For

• Revenue exceeding 500,000–1,000,000 PLN/year
• Building a product or SaaS business
• Multiple founders
• When personal liability protection is critical (security, fintech, healthcare software)
• Long-term reinvestment of profits

Sp. k. — Limited Partnership

How It Works

A partnership with at least two partners: one general partner (komplementariusz) with unlimited liability, and one or more limited partners (komandytariusze) with liability capped at their contribution.

Common structure: an sp. z o.o. acts as the general partner (protecting individuals from unlimited liability), with individuals as limited partners.

Taxes

Since 2021, sp. k. is subject to CIT at the entity level (9% or 19%), plus PIT on distributions to partners — creating double taxation similar to sp. z o.o. The 2021 change eliminated most tax advantages of sp. k.

Why It's Rarely Used for Solo IT Freelancers

• Requires at least 2 partners (or an sp. z o.o. as a partner)
• Complex structure with high setup and accounting costs
• Double taxation since 2021 removes the main historic benefit
• No meaningful advantage over sp. z o.o. for IT in most scenarios

When to Consider Upgrading from JDG to Sp. z o.o.

The Bottom Line for IT Freelancers in 2026

For a solo IT freelancer or contractor billing 15,000–50,000 PLN/month in Poland, JDG with ryczałt at 12% is almost certainly the best structure. Lower administrative burden, simpler accounting, favourable tax rates, and faster setup make it the clear winner at this stage.

Consider sp. z o.o. only when your revenue consistently exceeds ~600,000 PLN/year, you need liability protection for specific contract types, or you're building a business with employees or co-founders.
