🇵🇱 Poland — sp. z o.o. Owner ZUS Obligations in 2026

Does a sp. z o.o. owner get the same ZUS relief as a new JDG founder?

No. A new JDG founder gets a real, meaningful discount: no social contributions for the first 6 months (only health insurance), then a reduced "preferential" rate for the next 24 months, and the full rate only from month 31 onward.

None of that applies to a sole shareholder of a sp. z o.o., even if they take no salary at all. Those relief stages are tied to registering a JDG specifically — not to owning or running a company — so a sp. z o.o. owner pays full ZUS contributions from the very first month.

Is the health insurance base also different?

Yes. Under the tax scale and flat tax, a JDG has an income-linked health contribution with a minimum-wage floor; ryczałt instead uses revenue bands. A sole shareholder has no personal JDG income to use, so the company-shareholder title is charged at 9% of 100% of the prior fourth quarter's average wage — numerically the same base used for the middle ryczałt band in 2026.

Does this affect the choice between JDG and sp. z o.o.?

Yes, especially for an eligible person just starting out. A new JDG may have little social ZUS for the first six months, while a single-member sp. z o.o. shareholder pays full contributions immediately. A genuine multi-member company is treated differently, but adding a merely token shareholder may not reliably avoid sole-shareholder treatment.
