Everything you need to know before founding, during and after — costs, taxes, optimisation, mistakes to avoid.
1. When a Sp. z o.o. makes sense
Asset protection — liability limited to share capital (min. 5 000 PLN), not personal assets.
Scalability — easy to add partners, investors, or sell shares.
Optimisation with 2+ partners — no mandatory ZUS, greater salary flexibility.
Credibility — required by many large clients, banks, and grant programmes.
Estonian CIT — possibility of very low effective taxation.
2. Formation costs
3. Taxes — what a Sp. z o.o. pays
CIT — 9% (small taxpayer) or 19% (above ~9m revenue).
PIT on dividend — 19% on distributions to shareholders.
VAT — 23% (or reduced rates), depending on activity.
ZUS — only when there is a sole shareholder. With 2+ shareholders: no ZUS obligation from the company itself.
4. Estonian CIT — worth considering
See the full Estonian CIT guide →
An alternative to classical CIT — you pay tax only when you pay out profits. Often a 30–40% annual saving.
5. Obligations of a Sp. z o.o.
Full bookkeeping (commercial ledgers) — always, without exception.
Annual financial statements filed with KRS.
Beneficial owner entry (CRBR) within 7 days of registration.
KSeF from 1 July 2026 — mandatory.
JPK_V7M monthly (if an active VAT payer).
6. Most common mistakes in new companies
Missing CRBR entry — penalty up to 1 million PLN.
Incorrect settlement with the director (employment contract, B2B, contract for work — different consequences).
Mixing company and personal assets → risk of losing liability protection.
Failing to approve financial statements on time.
No minutes of shareholder resolutions → problems during a tax audit.
7. FAQ
How much does it cost to set up a sp. z o.o. in 2026?
Via S24 (online): PLN 250 in court fees + possibly PLN 17 in PCC. Classically via notary: from PLN 1,000 (notarial fee) + court fees. With our help: starter package PLN 1,499 net, company ready in 5 days.
What share capital is required?
Minimum PLN 5,000. Can be in cash or in-kind contribution. You don't need to deposit it before registration — a declaration is sufficient.
Sp. z o.o. or JDG?
Sp. z o.o. is worthwhile when: business risk (protection of personal assets), multiple founders, income above PLN 12–15k net/month, investment plans.
Do I need an accountant from day one?
Yes — a sp. z o.o. is required to keep full accounts from day one. You cannot use KPiR or lump-sum taxation.
What is Estonian CIT?
A form of taxation where you pay tax only when you distribute profit. Often wins for small and medium companies.
Can I be the sole shareholder?
Yes, but then you pay full ZUS (like a JDG). A second shareholder (even with 1% of shares) exempts from the ZUS obligation — this is a legal optimisation.
