B2B vs Employment Contract — Detailed Financial Comparison

Switching from an employment contract (umowa o pracę) to B2B is one of the most common career moves among Polish IT professionals, marketers, and consultants. The promise of higher earnings is tempting, but reality is more nuanced. How much do you actually gain, and what do you lose?

This article presents hard numbers — calculations for different salary levels, tax forms, and career stages.

How Employment Contracts Work — Costs and Mechanics

What the Employee Pays

From your gross salary, the following are deducted:

• Pension contribution (emerytalna): 9.76%
• Disability contribution (rentowa): 1.5%
• Sickness contribution (chorobowa): 2.45%
• Health contribution (zdrowotna): 9% (from the base after deducting social contributions)
• PIT advance: 12% or 32% (after deducting costs and the tax-free allowance)

What the Employer Pays

Additionally, the employer contributes:

• Pension: 9.76%
• Disability: 6.5%
• Accident insurance: 1.67% (average)
• Labour Fund (FP): 2.45%
• FGŚP: 0.1%

Result: At a gross salary of 15,000 PLN, the total employer cost is ~18,100 PLN, while the employee receives ~10,800 PLN net. The ~7,300 PLN difference goes to taxes and contributions.

How B2B Works — Costs and Mechanics

ZUS Contributions on B2B

On B2B, you pay ZUS yourself. The amount depends on your stage:

Start-up relief (first 6 months):

• Health contribution only: ~381 PLN (minimum on flat tax)
• No social contributions

Preferential ZUS (next 24 months):

• Social contributions from 30% of minimum wage: ~450 PLN
• Health contribution: depends on tax form

Full ZUS (after 30 months):

• Social contributions from 60% of projected average salary: ~1,600 PLN
• Health contribution: depends on tax form

Tax on B2B

Three options:

Flat tax (podatek liniowy) 19%:

• Health contribution: 9% of income
• Expense deductions: YES
• Tax-free allowance: NO

Progressive scale (skala podatkowa) 12%/32%:

• Health contribution: 9% of income
• Expense deductions: YES
• Tax-free allowance: 30,000 PLN

Lump-sum (ryczałt):

• Health contribution: fixed (~381–760 PLN/month)
• Expense deductions: NO
• Rate: 8.5%, 12%, or 15%

Calculations for Different Salary Levels

Scenario 1: 10,000 PLN (employer cost ~12,100 PLN)

Employment — 10,000 PLN gross:

• Employee contributions: 1,371 PLN
• Health: 776 PLN
• PIT: 483 PLN
• Take-home: 7,370 PLN

B2B — 12,100 PLN revenue (equivalent to employer cost):

Difference: On B2B you gain 722 PLN to 1,696 PLN more per month.

Scenario 2: 20,000 PLN (employer cost ~24,100 PLN)

Employment — 20,000 PLN gross:

• Take-home: ~15,058 PLN

B2B — 24,100 PLN revenue:

Difference: On B2B you gain 1,673 PLN to 4,169 PLN more per month.

Scenario 3: 30,000 PLN (employer cost ~36,200 PLN)

Employment — 30,000 PLN gross:

• Take-home: ~20,700 PLN (note: 32% bracket applies after exceeding 120,000 PLN annually)

B2B — 36,200 PLN revenue:

Difference: On B2B you gain 3,426 PLN to 8,796 PLN more per month.

What You Lose by Switching to B2B

Employee Rights

On B2B, you do not have:

• Paid vacation — 26 days × your daily rate = potential loss of 15,000–40,000 PLN/year
• Paid sick leave — illness = zero income
• Notice period — client can terminate in 1–30 days
• Severance pay — zero protection upon "dismissal"
• Employment protection — no protection during pregnancy, before retirement, etc.

Value of Lost Benefits

Let us calculate the real value of what you lose:

That is 2,500–5,000 PLN per month. Subtract this from your B2B "profit."

When B2B Pays Off — The Break-Even Point

After accounting for lost benefits, B2B truly pays off when:

• Your B2B rate is at least 30–50% higher than gross on employment
• You have real expenses to deduct (equipment, office, car)
• You are past the preferential ZUS period and still earning well
• You have multiple clients (risk diversification)

Approximate break-even points:

• At 10,000 PLN employment cost → B2B pays from ~14,000 PLN revenue
• At 20,000 PLN employment cost → B2B pays from ~26,000 PLN revenue
• At 30,000 PLN employment cost → B2B pays from ~36,000 PLN revenue

Legal Risks of B2B

Bogus Self-Employment

If you meet the following conditions, ZUS and the tax office may challenge your B2B arrangement:

• You work for only one client
• You have fixed working hours
• You work under the client's direction
• You use the client's equipment
• You bear no business risk

Consequences: Retroactive social security contributions + interest + penalties. This can mean a debt of tens of thousands of PLN.

How to Protect Yourself

• Work with at least 2–3 clients
• Use your own equipment
• Agree on flexible hours in your contract
• Run a real business (own website, marketing)
• Invoice for projects/results, not hours

Practical Steps — Transitioning from Employment to B2B

1. Financial Preparation

• Build an emergency fund: at least 6 months of expenses
• Calculate the real break-even point for your situation
• Factor in the cost of benefits you will lose

2. Setting Up Your Business

• Register in CEIDG (free, online)
• Choose your tax form
• Open a business bank account
• Select an accounting firm or bookkeeping software

3. Managing Your Finances

• Separate business and personal finances
• Set aside 30% of revenue for taxes and ZUS
• Monitor cash flow — Freenance helps track all aspects of freelancer finances in one place

4. Building Security

• Professional liability insurance
• Private healthcare
• Voluntary sickness insurance (if cost-effective)
• Client diversification

Summary

B2B offers higher net earnings but requires:

• Financial self-discipline
• An emergency fund
• Active tax and ZUS management
• Giving up the comfort of employment

The golden rule: If your B2B rate is not at least 30% higher than your gross employment salary — stay employed. The extra stress and risk are not worth a marginal difference.

Before making your decision, calculate your exact situation. Account for all costs — not just the visible ones (ZUS, taxes) but also the hidden ones (lost benefits, risk, time spent on administration). Only the full picture allows for a truly informed decision.
