PLN 7,000 gross is one of the most commonly searched salary amounts, and the answer to “how much is that net” depends not only on contributions but on what kind of contract you’re actually working under. Here’s the exact breakdown for an employment contract, a mandate contract (zlecenie), and B2B activity under a flat-rate tax, so the comparison is precise rather than just a rough guess.
- Under an employment contract, PLN 7,000 gross is about PLN 5,080 net a month, after employee ZUS contributions (13.71%), the health contribution (9%), and the PIT advance.
- Under a mandate contract (with no voluntary sickness contribution, for someone for whom this is their only insurance title), PLN 7,000 gross is about PLN 5,493 net, because you don’t pay the 2.45% sickness contribution that applies under employment.
- Under B2B activity (12% flat-rate tax for IT services, full ZUS), at PLN 7,000 revenue a month, you’re left with roughly PLN 3,756, because you pay the full ZUS contribution (PLN 1,788.49) regardless of how much you earn.
- These figures are approximate: PIT-2, tax reliefs, being under 26, or a different tax method all change the result.
- The lower your monthly revenue on B2B, the harder the fixed ZUS cost hits, because it’s the same amount whether you earn PLN 7,000 or PLN 17,000.

PLN 7,000 gross under an employment contract
Under an employment contract with PLN 7,000 gross, you subtract, in order: employee ZUS contributions (pension 9.76%, disability 1.5%, sickness 2.45%, together 13.71%), then the 9% health contribution on the base after social contributions, and finally the PIT advance (12% on the base after the PLN 250 standard deductible cost, minus the PLN 300 monthly tax-reducing amount).
| Item | Amount |
| Gross | PLN 7,000.00 |
| Employee ZUS contributions (13.71%) | PLN 959.70 |
| Health contribution (9%) | PLN 543.63 |
| PIT advance | PLN 417.00 |
| Net | PLN 5,079.67 |
PLN 7,000 gross under a mandate contract
Under a mandate contract (umowa zlecenie), for someone for whom this is their only insurance title, the pension (9.76%) and disability (1.5%) contributions are mandatory, while the sickness contribution is voluntary and isn’t paid in this calculation. The standard deductible cost is 20% (not the flat PLN 250 used for employment), which actually increases net pay compared to an employment contract at the same gross amount.
| Item | Amount |
| Gross | PLN 7,000.00 |
| Pension (9.76%) | PLN 683.20 |
| Disability (1.5%) | PLN 105.00 |
| Health contribution (9%) | PLN 559.07 |
| PIT advance (20% cost) | PLN 188.00 |
| Net | PLN 5,492.73 |
PLN 7,000 revenue on B2B (flat-rate tax)
Under B2B activity there’s no “gross” in the same sense as under a contract, there’s invoice revenue, from which you pay your own ZUS and tax. For a developer under a 12% flat-rate tax (the rate for software development services), with full (“large”) ZUS in 2026 (PLN 1,788.49 a month total, pension, disability, accident insurance, and Labour Fund, excluding voluntary sickness insurance), and PLN 7,000 in monthly revenue (which over 12 months gives you PLN 84,000 in annual revenue, the PLN 60,000-300,000 bracket, health contribution PLN 830.58):
| Item | Amount |
| Revenue | PLN 7,000.00 |
| Social ZUS (full, excluding sickness) | PLN 1,788.49 |
| Health contribution (PLN 60,000-300,000/year bracket) | PLN 830.58 |
| 12% flat-rate tax (on revenue minus social ZUS) | PLN 625.00 |
| Left roughly | PLN 3,755.93 |
At PLN 7,000 in revenue on B2B, full ZUS eats up nearly 25.6% of that amount before you even get to tax. That’s why at lower revenue it’s worth checking a preferential ZUS scheme or a different form of cooperation.
All three methods side by side
| Method | Gross / revenue | Left in hand |
| Employment contract | PLN 7,000 | PLN 5,079.67 |
| Mandate contract | PLN 7,000 | PLN 5,492.73 |
| B2B, 12% flat-rate tax, full ZUS | PLN 7,000 | ~PLN 3,755.93 |
Why B2B leaves the least at this amount
The difference isn’t because B2B is “worse”, it’s because full ZUS is a fixed amount, independent of revenue, which works differently from the progressive tax scale mechanism covered in our article on the second tax threshold. At PLN 7,000 in monthly revenue, the PLN 1,788.49 ZUS bill is nearly 25.6% of that, but the exact same ZUS amount at PLN 17,000 in revenue is only 12%. That’s why a “gross to net” comparison for B2B only makes sense in the context of a specific, real revenue figure, not as a universal rule. People just starting a business can also use preferential ZUS schemes (the start-up relief, then Mały ZUS Plus), which significantly improves this result in the first years.
If you’re still deciding which form of cooperation makes sense at your actual rate, it’s worth running the numbers on your own figures rather than just this one example amount. We cover the mechanism behind choosing a tax method in more detail in our article on revenue vs income, and if you’re starting from scratch and unsure whether a JDG is the right choice at all, our business incubator for freelancers is worth a look too, since it handles this accounting for you before you even register your own business.
Frequently asked questions
Is PLN 7,000 gross a good salary in Poland in 2026?
It depends on region and industry, but it’s close to the average wage in many sectors outside major cities and the IT industry. The net amount, roughly PLN 5,080, is worth comparing against actual living costs in your location.
Does a mandate contract always leave more net than an employment contract?
At the same gross amount and no voluntary sickness contribution, yes, because you skip the 2.45% sickness contribution and get a higher deductible cost (20% instead of PLN 250). In exchange, though, you have no right to paid leave or sick pay without paying that voluntary contribution separately.
Can I pay less than full ZUS on B2B?
Yes, if you’re just starting a business, you can use the start-up relief (6 months with no social contributions) and then Mały ZUS Plus (reduced contributions for a set period, depending on revenue). This article’s calculation assumes full ZUS, typical once those reliefs run out.
