B2B vs Employment for Programmers in 2026 - Complete Comparison
B2B or employment contract in 2026? Net pay comparison, Social Insurance contributions, and legal risks with current ZUS and health insurance rates.
Prefer to read with AI?
Choosing B2B or employment is not just about the net amount in your account. In 2026, Social Insurance contributions, tax thresholds, and the risk of a Labour Inspectorate audit change the equation enough to warrant recalculating everything from scratch. This article provides current figures, comparison tables, and concrete calculations, and at the end suggests when to run your own rate through Bookeper AI calculators.
Comparison methodology: In the tables
15,000 PLN / 20,000 PLN / 30,000 PLNI treat this amount as the monthly nominal rate: for employment it's the employee's gross salary, and for B2B the net value on the invoice.
What changed in 2026?
Several changes directly affect B2B vs employment profitability for programmers:
- Higher social ZUS contributions -- full ZUS with sickness insurance is now PLN 1,926.76/month (up from PLN 1,773.96 in 2025).
- Higher health insurance thresholds for lump-sum tax -- three brackets are 498.35 / 830.58 / 1,495.04 PLN respectively.
- Higher health insurance deduction limit for flat tax -- PLN 14,100 per year (was PLN 12,900 in 2025).
- Higher VAT exemption threshold -- PLN 240,000 (was PLN 200,000 in 2025).
- Higher minimum wage -- PLN 4,806 gross (affects preferential contributions and Small ZUS Plus).
- Small ZUS Plus -- extended to 36 months within a 60-month window (was 24/48).
Comprehensive comparison: Employment vs B2B
| Aspect | Employment (UoP) | B2B (sole proprietorship) |
|---|---|---|
| Taxation form | Progressive scale 12%/32% (no choice) | Lump-sum 12% / flat 19% / progressive 12-32% / IP Box 5% |
| Employee/entrepreneur ZUS | ~13.71% of gross | From PLN 0 (Startup Relief) to PLN 1,926.76/month |
| Employer ZUS | ~20.48% of gross (paid by employer) | None -- you pay all contributions yourself |
| Health insurance | 9% of base (non-deductible) | 4.9% (flat) / 9% (progressive) / flat-rate fixed amount |
| Tax-free amount | PLN 30,000/year | Only on progressive tax scale |
| Paid leave | 20-26 days | None -- every day off means no revenue |
| Sick leave | 80-100% of salary | Optional -- requires paying sickness contribution |
| Termination protection | Notice periods, special protections | None -- B2B contract can be terminated immediately |
| Liability | Limited (up to 3 months' salary) | Full personal asset liability |
| Flexibility | Low -- fixed hours, one employer | High -- multiple clients, your own terms |
| Credit score | Higher -- banks prefer employment | Lower -- requires 12-24 months of history |
| Benefits | Medical packages, training, MultiSport | None -- you buy them yourself |
| Administration | Zero -- employer handles everything | High -- accounting, ZUS DRA, SAF-T, VAT |
Net pay comparison: 15,000, 20,000 and 30,000 PLN
| Monthly rate level | Employment (net) | B2B lump-sum 12% | B2B flat 19% | B2B IP Box 5%* |
|---|---|---|---|---|
| 15,000 PLN | ~10,017 PLN | ~10,724 PLN | ~10,070 PLN | ~11,811 PLN |
| 20,000 PLN | ~12,562 PLN | ~15,124 PLN | ~13,922 PLN | ~16,328 PLN |
| 30,000 PLN | ~17,653 PLN | ~23,299 PLN | ~21,587 PLN | ~25,353 PLN |
* IP Box shown as an optional variant for programmers who actually meet R&D requirements and maintain qualified IP records.
Key takeaways:
- At 15,000 PLN B2B on lump-sum gives an advantage, but it's not massive. If you value paid leave, job stability and easier mortgage access, employment may still be a reasonable choice.
- At 20,000 PLN the difference becomes significant. Lump-sum gives about PLN 2,560 more net monthly than employment.
- At 30,000 PLN the B2B advantage grows strongest, as employment falls deep into the 32% bracket.
ZUS optimization path -- from PLN 0 to full contributions
1. Startup Relief (months 1-6)
For the first 6 full months you don't pay social contributions. You pay only health insurance.
- Social contributions: PLN 0
- Health insurance: PLN 432.54 -- 498.35/month
2. Preferential ZUS (months 7-30)
For the next 24 months you pay contributions from a reduced base (30% of minimum wage = PLN 1,441.80).
- With sickness: PLN 456.18/month
- Without sickness: PLN 420.86/month
3. Small ZUS Plus (up to 36 months within 60 months)
Available if previous year's revenue was below PLN 120,000.
4. Full ZUS (indefinite)
- With sickness: PLN 1,926.76/month
- Without sickness: PLN 1,788.29/month

| Total (excl. leave) | 530-1,450 PLN | 6,360-17,400 PLN |
When does B2B pay off?
B2B is worth it when:
- You invoice above PLN 15,000 net -- at lower amounts the tax benefit doesn't compensate for risks
- You have low fixed costs -- lump-sum 12% is most beneficial with low costs
- You have a stable contract for at least 6-12 months
- Your work model doesn't resemble employment -- multiple clients, own equipment
- You have a financial cushion -- 3-6 months of living expenses
Employment is better when:
- You need stability -- family, mortgage, no savings cushion
- You're planning parental leave -- ZUS benefits are significantly higher on employment
- You don't want to deal with administration -- accounting, declarations, VAT
- Your rate is below PLN 12,000 gross -- B2B benefit is minimal
