UoP vs B2B — What You Actually Take Home
Example: Mid Developer, 16,000 PLN Gross UoP
Employment contract (UoP):
- Gross: 16,000 PLN
- Employee ZUS: ~2,195 PLN
- Health insurance: ~953 PLN
- PIT advance: ~1,143 PLN
- Net: ~11,709 PLN
- Employer cost: ~19,280 PLN
B2B (12% lump-sum tax):
- Invoice (net): 19,280 PLN (equivalent to employer cost)
- ZUS (full): ~1,600 PLN
- Health insurance: ~660 PLN
- Lump-sum 12%: ~2,314 PLN
- Net: ~14,706 PLN
Difference: +2,997 PLN/month in favor of B2B. But remember: on B2B you don't get paid vacation (worth ~1,800 PLN/month annualized), sick leave, or severance pay.
Real Difference After Benefits
Accounting for vacation (26 days), sick leave, severance, and benefits (gym membership, private healthcare ~300 PLN), the real B2B advantage drops to ~1,500-2,000 PLN/month. Still significant, but requires financial discipline.
Factors Affecting Salary

How to Invest Your Surplus
With a median of 14,500 PLN gross (~10,400 PLN net) and average expenses of 6,000-7,000 PLN/month, you have 3,400-4,400 PLN to invest monthly.
The "60/20/20" Strategy for Developers
- 60% of surplus → Global ETF (e.g., VWCE / iShares MSCI ACWI) — long-term capital growth
- 20% of surplus → Government bonds (EDO, COI) — stability and inflation protection
- 20% of surplus → IKZE (retirement account) — tax deduction of ~1,200-2,400 PLN/year
Savings Simulation
| Monthly savings | 5 years | 10 years | 15 years |
|---|---|---|---|
| 2,000 PLN | 143,000 PLN | 350,000 PLN | 650,000 PLN |
| 3,500 PLN | 250,000 PLN | 612,000 PLN | 1,137,000 PLN |

FAQ
Can a junior developer earn 12,000 PLN?
Yes, but typically in Warsaw, at a foreign company, or in a niche technology (Go, Rust). A typical junior at a mid-size Polish company earns 8,000-10,000 PLN gross. Key: internships and commercial projects during studies.
How much does a developer earn working remotely for a US company?
A senior developer working remotely for a US company typically earns $5,000-$10,000/month (21,000-42,000 PLN). On B2B with 12% lump-sum tax, net is 17,000-35,000 PLN. That's 2-3x more than the domestic market.
When should a developer switch to B2B?
When gross exceeds 12,000-15,000 PLN. Below that, the UoP tax-free allowance and employer benefits can outweigh B2B advantages. Above it, the difference grows in B2B's favor.
Is it worth learning Go or Rust for higher pay?
Yes — Go/Rust seniors earn 15-30% more than Java/Python at comparable levels. But note: smaller job market. Best strategy: solid foundation (Python/Java/JS) + niche technology as a second skill.
