B2B vs Employment – comparison calculator 2026

The answer depends on your income level, tax form and stage of business. With revenue above 7,000–8,000 PLN/month, B2B usually leaves more net — especially with 12% lump-sum or flat tax. At lower amounts UoP can have the edge because the employer covers part of ZUS. Use the B2B vs UoP calculator to check your specific case.

The approximate break-even point for B2B (with full ZUS) is around 7,000–9,000 PLN/month. Below that, high ZUS contributions can offset the tax advantage. At higher revenues — especially with 12% lump-sum or 5% IP Box — the B2B advantage grows quickly. Use the comparison calculator to find the exact threshold for your situation.

On B2B, the entrepreneur chooses the most favourable tax form (e.g. 12% lump-sum or 5% IP Box) and can deduct business costs. On UoP, contributions and tax are less flexible. With the right rate and efficient taxation, the effective tax burden on B2B can be significantly lower than total employment costs on UoP.

Key B2B advantages: higher net pay at the right revenue level, ability to deduct business costs (equipment, office, training, car), freedom to choose your tax form (lump-sum, flat tax, IP Box), flexibility in setting rates with clients and the ability to work with multiple clients simultaneously. No cap on earnings from a single client.

B2B disadvantages: no paid leave or sick pay (unless you buy voluntary sickness insurance), you must manage your own accounting and pay ZUS regardless of revenue, no protection against contract termination, no severance or minimum wage guarantee. You also need to register your business and handle all admin yourself.

Employment is better when your salary is low (below ~6,000–7,000 PLN gross), you value job stability and employee protections, you need paid leave or sick pay, you don't want to deal with business admin, or your industry requires employment. UoP also provides greater social security and employee benefits.

Yes. An employee on UoP pays ZUS on gross salary (the employer adds their share). A B2B entrepreneur pays ZUS on a fixed contribution base: with full ZUS ~1,773 PLN/month (2026), with preferential ZUS ~408 PLN/month, and with ulga na start — 0 PLN in social contributions. The structure and bases differ significantly from those of employees.

Compare net take-home amounts. Enter the B2B rate and the equivalent UoP gross in the B2B vs UoP calculator — it instantly shows net pay for both. Remember to account for B2B costs: accounting, private health insurance and unpaid days off, which reduce the real financial advantage of B2B.

Yes. On the B2B side you can choose any tax form: lump-sum (ryczałt, rates 2–17%), flat tax 19% (with IP Box 5% option) or progressive scale (12%/32%). Each form gives a different net result — the calculator computes it live and compares it with UoP salary, helping you find the optimal configuration for your situation.

The calculator runs two computation engines in parallel: the B2B calculator and the UoP calculator. For B2B it computes net income after deducting tax, ZUS and health insurance. For UoP — net after deducting employee contributions and PIT advance. It then compares the results and shows the absolute difference in PLN and the percentage advantage of one form over the other.
