A mid-level software engineer in Poland earns a median of about 231,000 zl a year in 2026. Warsaw pays about 6.3% above that and Poznan about 5.4% below, a narrower spread than most European markets.
The bigger number is the contract type. At the same 19,038 zl a month, umowa o prace nets 12,072 zl while B2B on ryczalt nets 14,277 zl, about 18% more for identical gross.

This is 19,038 zl a month, the mid-level benchmark, run through each Polish regime with our tax engine. The gross never changes. Only the rules do.
| Regime | Net a month | Effective rate | What comes with it |
|---|---|---|---|
| Umowa o prace (UoP) | 12,072 zl | 36.6% | Full employment rights, sick pay, paid holiday |
| B2B, skala podatkowa | 12,395 zl | 34.9% | Progressive rates, no employment protection |
| B2B, podatek liniowy | 13,181 zl | 30.8% | Flat 19%, no joint filing or child relief |
| B2B, ryczalt 12% | 14,277 zl | 25.0% | No expense deductions at all |
Note how little B2B on the progressive scale gains: 323 zl a month over employment, for which you give up every employment protection. If you are going B2B, the regime choice is where the money is, not the contract type by itself.
Gross and net by level, on umowa o prace
| Level | Gross a year | Net a month |
|---|---|---|
| Junior | 144,400 zl | 8,506 zl |
| Mid-level | 228,450 zl | 12,072 zl |
| Senior | 318,800 zl | 16,106 zl |
| Lead or Architect | 422,350 zl | 21,072 zl |
How solid are these numbers?
The city medians and the national figure are measured mid-level benchmarks from PayMetric's 2026 Polish dataset, drawn from a single source with a confidence score of 0.65. The junior, senior and lead bands are modelled outward from that mid-level point rather than measured separately. Every net figure on this page, including the four regimes above, is computed with our Polish tax engine at 2026 rates. For the current market range see software engineer salaries in Poland.
Five cities, under 13% between them
| City | Mid-level median | Against the national figure |
|---|---|---|
| Warsaw | 245,450 zl | +6.3% on the national median |
| Wroclaw | 233,500 zl | +1.1% |
| Krakow | 231,000 zl | the national median |
| Gdansk | 226,500 zl | -1.9% |
| Poznan | 218,550 zl | -5.4% |
Krakow, Wroclaw and Gdansk sit within 2% of the national median, and Warsaw's 6.3% premium does not cover the difference in rent. Choosing a Polish city on pay alone is not worth much. Choosing the right contract regime is worth roughly three times as much.
Could IP Box apply to your work?
If you are B2B and writing original software, the 5% rate on qualifying IP income can change the arithmetic again. Work out what share of your billing might qualify.

Frequently asked questions
What does a software engineer earn in Poland in 2026?
The national mid-level median is about 231,000 zl a year, with the middle of the market between roughly 226,500 zl and 233,500 zl. Warsaw pays about 6.3% above that and Poznan about 5.4% below. The city spread is narrow: under 13% between the highest and lowest of the five main tech cities.
What does 228,450 zl leave after tax on umowa o prace?
About 12,072 zl a month, an effective deduction rate near 36.6% once PIT, ZUS social contributions and the 9% health contribution are taken. That is the highest effective rate of any market on our Latin American and Asian benchmark pages, and it is why so much Polish engineering work runs on B2B instead.
How much more does B2B actually pay at the same rate?
On the same 19,038 zl a month, umowa o prace nets 12,072 zl while B2B on ryczalt at 12% nets about 14,277 zl. That is roughly 2,205 zl a month more, or about 18%, for the same gross. Podatek liniowy lands at 13,181 zl and B2B on the progressive scale at 12,395 zl, barely ahead of employment.
So is B2B always better?
No. Those figures are net of tax but not net of what you give up: paid holiday, sick pay, notice, ZUS accrual toward a pension and, at the start, the cost of running a company. Ryczalt also allows no expense deductions at all, so it only wins when your costs are genuinely low. And the IP Box regime can drop the rate on qualifying software income further, which changes the comparison again.
How reliable are the level bands on this page?
Treat them as a shape, not a measurement. PayMetric's 2026 Polish dataset measures the mid-level market from a single source with a confidence score of 0.65. The junior, senior and lead figures are modelled outward from that mid-level benchmark, not observed separately. The city medians are measured, and the net figures for every regime come from our Polish tax engine.
What is IP Box and does it apply to me?
IP Box taxes qualifying income from intellectual property rights at 5% rather than 19%. For a B2B developer creating original software it can apply to the part of income attributable to that IP, but it requires proper records separating qualifying income and a defensible basis for the split. It is not automatic and it is not a blanket 5% on everything you bill.
Why does my offer look different from these numbers?
Almost always the contract type. A B2B rate and a UoP salary are not the same currency: the B2B number has to cover everything the employer would otherwise pay, including ZUS, holiday and sick leave. A recruiter quoting 22,000 zl B2B against a 19,000 zl UoP offer is not offering you a raise. Run both through the comparison before deciding.
Are Polish tech salaries still growing?
The dataset shows about 7% year-on-year growth. Poland is no longer the low-cost option in the EU it was a decade ago, and the biggest employers are increasingly Polish and international product companies rather than outsourcing centres. Growth is strongest in the senior bands where the shortage is real.
Salary figures are PayMetric Labs' own modelled estimates from a 2026 single-source dataset with a confidence score of 0.65, not a survey or an offer. Level bands are modelled from the measured mid-level benchmark. Net figures come from our Polish tax engine at 2026 rates, for a single taxpayer with no child relief and no IP Box claim.
