Employee vs B2B contractor in Poland

Nadia was one email away from closing a hire that had dragged on for two months.

She runs a Swedish software house, and she had just found the senior she really wanted — a developer from Kraków who, in the technical interview, took her architecture apart and put it back together better than it was before. The team wanted him. She wanted him. One step remained: the form of the engagement.

And here the developer said something that sounded like a gift: “You don’t need to put me on an employment contract. I’ll invoice you — B2B, the way almost everyone in Polish IT works.”

Nadia was relieved. No employer payroll setup, she thought — simpler and cheaper. But the contract label alone would not settle either party’s obligations. She was about to write “great, let’s draw up the contract” when a friend of hers, a Pole who runs a business there and to whom she had shown the details, cut in. He replied briefly: “Check how the work will actually be organised. Working under your direction and within your working arrangements can point towards employment. The whole relationship needs to be assessed — and the labour inspectorate has stronger tools from July 2026.”

Nadia wasn’t doing anything dishonest. She simply wanted to hire a good person by the simplest route. The snag is that in Polish IT the simplest route and the safest route aren’t always the same one — and the rules have just changed.

This story comes up at Certa Poland almost every week. Below: when B2B is fine, when it becomes a trap, and how Nadia worked out which side she was on — before she signed.

(The 2026 reform section was checked against official sources on 3 October 2026. This is general information, not legal or tax advice. The characters are illustrative examples. We confirm your case individually, in writing.)

The short answer: B2B can be fine, but not always — and the rules have just tightened

A B2B contract with a Polish IT specialist is legal and often sensible — but only when it describes a genuinely independent relationship between two businesses. If in practice it looks like employment — particularly work under the engager’s direction and within working arrangements the engager controls — then, whatever the contract is called, there’s a risk it will be treated as an employment relationship. Having one client does not decide the classification by itself.

Since 8 July 2026, Poland’s labour-inspectorate reform has provided an administrative route for a district labour inspector to establish an employment relationship after a prior instruction to remedy the breach has not been followed. The parties can appeal to the labour court. Genuine independent contracting remains lawful; the practical question is whether the chosen contract matches the work.

Why “everyone in Polish IT is on B2B”

Nadia’s developer wasn’t making it up — in Poland’s IT sector self-employment (a sole proprietorship, “JDG”) is very common. The reason is mainly tax: someone running their own business can use more favourable tax treatment and lower social-security contributions than an employee. Many experienced developers choose this deliberately and genuinely run their own business — several clients, their own equipment, their own way of organising the work.

So the problem isn’t that B2B is “bad”. It’s that the same form is used for two different things: for a genuine relationship between independent businesses — or to disguise ordinary employment so both sides pay less. The 2026 reform targets the second.

Employee or B2B: what actually differs for you

Before you decide, it’s worth seeing what separates the two models from an employer’s perspective:

• Cost and charges — with employment you bear the contributions and payer obligations; with B2B the contractor handles their own tax and ZUS settlements. But “cheaper” on B2B can be illusory if the contract is really employment (see below).
• Direction and organisation — an employee can be subject to the company’s direction and control (hours, place, instructions). An independent contractor decides for themselves how and when they work. That’s one of the key tests.
• Copyright / IP — an underrated difference: for computer programs created by an employee in the course of their duties, the employer generally acquires the economic copyright by operation of law (Article 74(3) of the Copyright Act), whereas with B2B the rights have to be expressly assigned in the contract (Articles 41 and 53). Without that assignment, you can be paying for code whose rights you don’t hold.
• Benefits and protection — employment means paid leave, sick pay and protection on dismissal. B2B gives none of that — an advantage for a genuine business, a problem if it was really employment.
• Team stability — an employee is tied to the company; a contractor is an independent supplier of services.

The 2026 labour-inspectorate reform: where the risk lies

The assessment concerns how the work is performed in practice. Direction, organisation, responsibility and business risk need to be considered together. A single feature, such as having one client or using the client’s equipment, does not decide the classification by itself.

The main changes in force since 8 July 2026 are:

• A procedure before a decision. The parties can state their positions. A district labour inspector can then establish employment by administrative decision if the prior instruction to remedy the employment breach has not been followed.
• An appeal to the labour court. A timely appeal ordinarily postpones enforceability until a final court ruling. A decision can, however, be given immediate enforceability; an appeal is not an unconditional stay in every case.
• Higher penalties for relevant offences. The general Labour Code fine band for the offences affected by the reform is now PLN 2,000–60,000. Other bands and on-the-spot fine limits depend on the specific offence and circumstances.
• Limited transitional relief. For eligible arrangements already in place before 8 July 2026, voluntarily entering into an employment contract within 12 months of the reform taking effect on that date can remove liability for the specific offence of using a civil contract in place of employment. The period does not restart when an individual contract is signed. This is not a general cancellation of tax, social-security or employee claims.
• An individual interpretation. An eligible engager can request an interpretation from the Chief Labour Inspector. It binds PIP for the applicant and the facts described; it does not bind ZUS, the tax authorities or the courts.

For a foreign employer, the useful next step is a documented review of the working arrangement, followed by a properly planned change where employment is required.

Nadia had not yet signed, so her review concerned the proposed arrangement. If you already have a contractor in place, include the earlier period in the review with the relevant legal and tax advisers. The consequences depend on the facts and the applicable procedures.

Two things are worth adding:

• A Swedish head office does not settle the applicable law. If the relationship is employment, choosing a foreign law cannot remove the mandatory employee protections that would apply without that choice under the Rome I Regulation. The country in which or from which the employee habitually works is normally the starting point, but the relationship may be more closely connected with another country. A cross-border arrangement needs that assessment.
• Not every contractor is a time bomb. One collaborator is a different scale from fifty people on B2B in a single open-plan office. But Nadia’s situation — one client, her hours, her team — was worth checking.

When B2B is safe, and when it’s risky

Use these indicators to prepare a review, not to decide the classification yourself. No single item is decisive; the whole working arrangement matters:

Usually fine:

• the specialist has several clients, not just you,
• decides for themselves when and how they work,
• uses their own equipment and bears their own business risk,
• is paid for a result or a project, not simply for putting in the hours.

Getting risky:

• you are their only client,
• they work the hours you set,
• they’re part of the team and take instructions like an employee,
• the arrangement has run for a long time and looks identical to the employment of the colleagues beside them.

Nadia’s proposed working arrangement called for a closer review, especially the direction and control she expected to exercise. If that review points to employment, a foreign employer can also assess the direct-employment route described in this guide without assuming that a Polish company must be the first step.

What to check before you sign

• Does the specialist genuinely run an independent business (several clients, own tools, own risk)?
• Will the relationship be based on subordination and fixed hours — or on independently delivering tasks?
• How will you assign the rights to the code (IP)?
• At this scope, wouldn’t employment be safer from the outset — and do you even need a Polish company for it (not always)?

Moving from B2B to employment with a clear handover

If you are reviewing a contractor arrangement, start with how the work is actually organised. Who assigns tasks? Who directs how they are completed? What can the specialist decide independently? Collect examples from everyday work alongside the agreement. A single feature does not settle the classification of the relationship.

Once the appropriate route has been assessed, prepare the change as a joint HR, finance and operations task:

Prepare	Resolve before the handover
Scope and timing	Agree the future role, reporting line and intended employment start.
Compensation	Compare the proposed gross salary, employer budget and benefits with the current commercial arrangement.
Existing contract	Have the relevant adviser review how the current agreement ends and what obligations remain.
Work product and access	Check IP provisions, confidentiality, equipment and system access.
First payroll	Confirm the required employee information, registrations and monthly responsibilities.

Give the adviser a timeline covering the earlier agreement as well as the proposed change. Ask which periods and obligations the review will cover, and include any unresolved questions in the handover.

For a foreign company, the next practical question is who will be the employer. Read about hiring an employee in Poland without your own entity and the monthly payroll process, then request an assessment of your route.

Have a developer in Poland on B2B and not sure it’s safe?

Like Nadia — before you sign, it’s worth checking whether it’s real B2B or employment in disguise, which from July 2026 an inspector can formally challenge.
