Poland Can Now Cancel Your B2B Contract Without a Court. Her

Since 8 July 2026 Polish labour inspectors can rule that a B2B contract is really employment — administratively, no lawsuit. The five markers they assess, what the advisers disagree about, and how to audit your own contract in ten minutes.

Roughly half the senior engineering roles advertised in Poland are structured as B2B — you invoice, you pay your own ZUS, you take home more. On 8 July 2026 that arrangement stopped being purely a matter between you and your employer. Poland's labour inspectorate can now issue an administrative decision declaring your contract an employment relationship, without suing anyone first. This is what they look at, and what nobody can tell you yet. Verified against primary and legal-adviser sources on 9 September 2026.

What actually changed on 8 July

Before that date, if the State Labour Inspectorate (PIP) believed a self-employment arrangement was really a job, it had to go to court and prove it. That is slow, expensive, and rare — which is why the B2B model spread through Polish tech almost unchallenged for fifteen years.

Now the inspector issues an order to conclude an employment contract. If the order is ignored, the district labour inspector issues a decision, and that decision stands as an administrative fact. The dispute moves to a labour court only if someone appeals it. The burden of initiating the fight has flipped, and that is the whole reform in one sentence.

The contract type did not become illegal. It became cheap to challenge. Those are very different things, and most of the panic online confuses them.

The five markers

Inspectors assess how the work is actually performed, not what the contract calls it. Renaming yourself a "vendor" changes nothing. Across the legal analyses published since July, the same five markers recur.

One: fixed hours. You are expected online 9 to 6, or you log hours rather than deliverables. Two: paid for time, not results. Your invoice is hours × rate, month after month, with no deliverable attached. Three: supervision. Someone assigns your tasks day to day, reviews your work, and can tell you how to do it, not just what to deliver.

Four: no right of substitution. Your contract requires you personally, and you could not send a qualified replacement even if you wanted to. Five: integration. You sit in the org chart, attend internal reviews, use company hardware and accounts, and have exactly one client — the same one, for years.

None of these is fatal alone. Plenty of genuine contractors work fixed hours for one big client. The picture that draws an inspector is all five at once, which — be honest — describes a large share of engineers currently invoicing Polish employers.

Audit your own contract in ten minutes

Open your contract and answer five questions with yes or no. Does it name working hours or availability windows? Is payment calculated on time rather than delivered scope? Does it give the client a right to instruct you on method? Does it forbid substitution or subcontracting? Does it require you to use client-provided equipment and systems?

Four or five yeses and your arrangement looks like employment on paper. That is not a prediction that anything will happen to you — it is the answer to the question your employer's lawyer is currently asking about their whole contractor base. Knowing the answer before your renewal conversation is worth more than any amount of forum reading.

What nobody can tell you yet

Three things are genuinely unsettled, and any page that states them with confidence is guessing. The appeal window: advisers have published both 7 days and 30 days. The retroactive reach: some analyses say three years of back contributions and holiday pay, others five. And whether a formal regularisation period exists — one prominent firm describes a twelve-month window to fix arrangements, others do not mention it at all.

The reason for the spread is that guidance was written at different stages of the legislative process, and a lot of it was copied rather than checked. If a number matters to your decision, get it from your own lawyer against the current text, not from a blog — including this one.

What this means if you are moving to Poland

If you have an offer in hand and it is B2B, the important question is not whether B2B is safe. It is whether your employer has done the audit. Ask directly: have you reviewed your contractor arrangements since July, and what did you change? A company that answers with specifics has thought about it. A company that says "everyone here works B2B, it's normal" has told you something too.

Ask one more thing: if my contract were reclassified, what happens to my residence permit? For most permits, the legal basis is tied to the specific arrangement you declared. A change in contract form is not automatically neutral for your right to stay, and that is the part almost nobody raises in the salary negotiation.

And if the answer is that B2B is non-negotiable, price it. The gap between a B2B rate and an equivalent employment salary is compensation for risk you are carrying. It has always been. As of July, there is simply more of it.
