Tax Authority Rules: When B2B is "Fake"

Polish tax authorities closely scrutinize B2B contracts to prevent abuse. B2B is considered "fake" (should be employment) if:

• Exclusivity: Contractor works only for one client
• Control: Client controls work hours and methods
• Permanence: Contract is indefinite or very long-term
• Integration: Contractor treated like employee (attends meetings, uses company systems)
• Compensation: Payment is stable monthly salary equivalent

If tax authority determines B2B is fake, both parties face penalties.

FAQ: Employment vs B2B Decision

Is B2B cheaper for business?

Short-term yes (15% lower costs). But if tax authority reclassifies it, you face significant penalties. Employment is legally safer.

Can I use B2B for permanent positions?

Legally yes, but risky. Tax authorities watch for this. If work appears permanent/exclusive, reclassification risk is high.

What if contractor says they prefer B2B?

Contractor preference doesn't matter for tax purposes. If relationship looks like employment, it is employment regardless of what parties call it.

Can I have both employees and B2B contractors?

Yes. Use employment for core team, B2B for occasional specialized work. This is normal and acceptable.

What happens if I get audited?

Tax authority will examine contracts, payment patterns, work arrangements. If B2B looks like employment, you'll face back-taxes (including employer ZUS), penalties and interest on several years of payments.
