Sole proprietorship or LLC — which is better in Poland in 2026?

Q: When an LLC makes sense tax-wise

A spółka z o.o. is worthwhile when: 1. You reinvest profit. CIT 9% instead of PIT 19% — more stays for growth. 2. You have high personal costs. In an LLC you can pay a board member salary (a deductible cost for the company) and settle under the tax scale. 3. You need asset protection. Liability limited to capital. 4. You plan to work with investors. The share structure is flexible.

Sole proprietorship (JDG) vs. LLC (spółka z o.o.): taxes, ZUS, accounting costs, liability. Concrete 2026 numbers, no marketing fluff.

JDG and spółka z o.o. are the two most popular business forms in Poland. The choice isn't obvious — it depends on how much you earn, whether you reinvest, whether you need asset protection, and whether you employ anyone besides yourself. Below are concrete numbers for 2026, no theorizing.

Quick comparison

Registration: JDG — free in CEIDG (Central Registration and Information on Business), ready in 1 day. LLC — from 350 zł (S24) to 1500+ zł (notarial deed), registration in KRS (National Court Register) takes several days.
Starting capital: JDG — 0 zł. LLC — minimum 5 000 zł share capital.
Accounting: JDG — KPiR (tax revenue and expense ledger) or lump-sum revenue register (from 170 zł/mo). LLC — full accounting, mandatory (from 500 zł/mo).
Liability: JDG — all personal assets. LLC — up to the amount of contributed capital.
Taxes: JDG — tax scale 12%/32%, flat 19% or lump sum 2–17%. LLC — CIT 9% (small taxpayer) or 19%, plus 19% PIT on dividends.
ZUS (Social Insurance Institution): JDG — relief (6 months free, 24 months reduced). Single-member LLC — full ZUS from day one, no relief.

Taxes: what you actually pay

JDG

On a JDG you choose your taxation form:

Tax scale (12%/32%) — tax-free allowance of 30 000 zł, threshold at 120 000 zł. Good for lower incomes and with a child.
Flat rate (19%) — no tax-free allowance, but a single bracket. Stable at higher incomes.
Lump sum (2–17%) — you pay on revenue, without deducting costs. Best for services with low costs.

The maximum effective rate on a JDG is 19% (flat) or 32% (tax scale, second bracket).

Spółka z o.o.

The company pays CIT on profit:

9% CIT — if revenue does not exceed 2 million EUR (small taxpayer, Art. 2 point 25a of the CIT Act).
19% CIT — standard rate above this limit.

But that's not all. When you want to take money out of the company as a dividend, you pay an additional 19% PIT (Art. 30a sec. 1 point 4). The effective burden on profit withdrawn from the company is:

CIT 9% + PIT 19% = approx. 26% (for a small taxpayer)
CIT 19% + PIT 19% = approx. 34% (for the standard rate)

This is the key difference. On a JDG you pay once (max 19% flat). In an LLC you pay twice — unless you leave the profit in the company.

When an LLC makes sense tax-wise

A spółka z o.o. is worthwhile when:

You reinvest profit. CIT 9% instead of PIT 19% — more stays for growth.
You have high personal costs. In an LLC you can pay a board member salary (a deductible cost for the company) and settle under the tax scale.
You need asset protection. Liability limited to capital.
You plan to work with investors. The share structure is flexible.

When JDG is better

JDG wins when:

You withdraw everything. No double taxation — 19% flat and done.
You're starting out. 0 zł capital, startup relief (6 months without social ZUS), preferential ZUS (24 months).
You have low costs and simple operations. KPiR or lump sum, cheap accounting.
You don't need asset protection or you have separate OC (liability) insurance.

ZUS: an LLC pays more from day one

JDG

Startup relief: first 6 months without social contributions (you pay only health insurance).
Preferential ZUS: next 24 months on a lower base (30% of minimum wage = 1 441,80 zł).
Full ZUS: 1 926,76 zł/mo (social with sickness) + health insurance.

Single-member spółka z o.o.

No relief. Full social contributions from day one: 1 926,76 zł/mo.
Health contribution calculated as under the tax scale (9% of income, minimum 432,54 zł).
In 2026 the combined minimum is approx. 2 359 zł/mo.

Multi-member LLC (≥2 partners)

Partners in a multi-member spółka z o.o. are not subject to mandatory social insurance (Art. 6 sec. 1 point 5 of the Act on the Social Insurance System). This is a significant cost advantage — but a 2024 Supreme Court (SN) resolution confirmed that a "sham partner" (e.g. holding 1% of shares) does not release the main partner from ZUS.

Running costs

| Item | JDG | Spółka z o.o. | |---|---|---| | Registration | 0 zł | 350–1500 zł | | Share capital | 0 zł | min. 5 000 zł | | Accounting/mo | 170–350 zł | from 500 zł | | ZUS first year | from 0 (relief) | 2 359 zł/mo | | Full ZUS/mo | 1 926–2 400 zł | 2 359 zł/mo |

Personal liability

JDG: you are liable with all your personal assets — your home, car, savings. A creditor can seize everything, except assets excluded from enforcement.

Spółka z o.o.: a partner is liable up to the amount of their contribution. If the company goes bankrupt, your personal assets are safe. But note: the management board is jointly and severally liable for public-law obligations (ZUS, Tax Office) — here the protection is weaker.

What about accounting?

A JDG can keep a KPiR (tax revenue and expense ledger) or — on the lump sum — a simple revenue register. It costs from approx. 170 zł net/month. Full accounting applies only above the 2 million EUR revenue threshold.

A spółka z o.o. must keep full accounting books always, regardless of revenue. This means higher accounting costs (from 500 zł/mo) and more extensive financial reporting.

Practical decision: checklist

Choose JDG if:

You're starting out and don't know if the business will take off
You withdraw most of the profit for living expenses
You have low fixed costs
You don't need personal asset protection
You want minimal formal costs

Choose spółka z o.o. if:

Revenue is growing and you reinvest a significant portion
You need asset protection (B2B contracts, litigation risk)
You plan to bring in an investor or share the business
Your business has a high risk of liabilities
You've crossed the threshold where CIT 9% + reinvestment beats PIT 19%

How much you'll pay — comparative example

Assume: 100 000 zł of income (profit) that you want to withdraw in full.

JDG (flat 19%):

Tax: 19 000 zł
Remaining: 81 000 zł

Spółka z o.o. (CIT 9% + dividend 19%):

CIT (9%): 9 000 zł
Profit after CIT: 91 000 zł
PIT on dividend (19%): 17 290 zł
Remaining: 73 710 zł

Difference: 7 290 zł in favor of JDG.

Now the same profit, but reinvested (left in the company):

JDG: you paid 19 000 zł PIT. Available for reinvestment: 81 000 zł.

Spółka z o.o. (9% CIT): you paid 9 000 zł CIT. Available for reinvestment: 91 000 zł. Difference: +10 000 zł for the LLC.

Conclusion: if you withdraw — JDG. If you reinvest — LLC.
