FAQ

How much does a full-stack developer earn in Poland in 2026?

Junior full-stack developers earn 8 000–10 400 PLN gross monthly on UoP, mid-level 14 000–18 200 PLN and senior 22 000–30 800 PLN. On B2B the same experience typically translates to 16 000–28 000 PLN net per month after ZUS and accounting costs. Stacks combining TypeScript with cloud (AWS/GCP) and a backend language like Java, Go or .NET sit at the top of these ranges.

Is B2B or UoP better for a full-stack developer in Poland?

B2B usually nets 20–35% more for mid and senior developers thanks to flat 19% PIT, deductible expenses and lower ZUS in the first months, but you trade away paid leave, sick pay and employer-funded benefits. UoP is often the safer pick for juniors who want stability, parental rights and clear social-insurance coverage. Run a side-by-side calculation with realistic accountant and ZUS Plus costs before switching.

Does IP Box apply to full-stack developers?

Yes — code that is original and qualifies as a computer program under Polish copyright law can be eligible for the 5% IP Box rate on the qualifying portion of income. You need proper documentation (KPiR, time-tracking, identification of qualifying IP) and ideally a tax ruling. Combined with B2B structure, qualifying developers often reach effective tax rates near 8–12% on a large share of income.

How do salaries compare across Polish cities for developers?

Warsaw remains the baseline; Kraków and Wrocław come in at 88–95%, Gdańsk and Poznań 85–92%, Łódź 80–88%. Remote work for foreign clients can exceed Warsaw rates by 30–60% when billing in EUR or USD. Cost of living scales similarly, so net purchasing power across mid-sized cities is often close to Warsaw.

How should a full-stack developer plan emergency fund and investing?

Aim for 3–6 months of expenses in liquid savings — roughly 29 400–58 800 PLN at typical developer cost structures, with B2B contractors leaning toward 6 months because they carry their own risk. After that, allocate 15–20% of net income to globally diversified equity ETFs inside an IKE for tax-sheltered growth. Freenance lets you track net worth, runway and progress to financial independence in one place.
