Changes to B2B contracts in 2026?

At the intersection of economics, law and day-to-day business practice, B2B contracts have for years served as a safety valve for the Polish labour market. For many entrepreneurs and professionals, self-employment has meant freedom, whilst for companies it has meant efficiency and cost predictability. However, the forthcoming changes to B2B contracts in 2026 are causing concern that goes far beyond simply adapting documents to the new regulations. Some experts and media outlets simplify the narrative: ‘the end of bogus self-employment’, ‘equal rights at last’, ‘the National Labour Inspectorate will gain new powers’. Meanwhile, the real tension lies elsewhere – in the growing disconnect between the idea of a flexible labour market and the mounting regulatory and tax pressures that risk stifling the spirit of entrepreneurship.

The line between contract work and permanent employment – an illusion of control or a practical tool?

The biggest misconception surrounding the changes to B2B contracts in 2026 is the belief that simply drafting a few clauses correctly is enough to protect against the risk of a contract being reclassified as a permanent post. The new B2B 2026 regulations place in the hands of PIP inspectors a tool that operates like Ockham’s razor: it does not matter what you call the contract – what matters is what the day-to-day collaboration actually looks like. If a self-employed person carries out instructions, is subject to supervision, works during hours specified by the client and uses the client’s tools, the inspector may immediately – by administrative decision – determine that the arrangement constitutes permanent employment.

These are no longer protracted court battles in which each party could present their arguments. From 2026, in accordance with the 2026 B2B contract regulations, the inspector’s decision takes immediate effect – the company must treat the contractor as an employee, regardless of the contractor’s wishes. An appeal does not suspend the effects of the decision. The paradox is that even if a self-employed person consciously chooses the flexibility of a B2B arrangement, an official may ‘know better’ what is good for them.

Is the fight against bogus self-employment really about protecting workers’ rights?

The 2026 B2B legislative changes are presented as a shield protecting those forced into self-employment. However, the reality is more complex. For many professionals, particularly in IT, consultancy or the creative industries, B2B is not a compulsion but a conscious choice and the key to professional development. The ability to work for several clients, set one’s own schedule and determine terms of remuneration are values that cannot be reduced to the simple dichotomy of ‘exploited worker – bad employer’.

Example: Anna, a software developer from Wrocław, has spent years building up her portfolio as a freelancer, choosing projects and negotiating her rates. The new legal reality may force her main client to employ her on a permanent basis, which will restrict her freedom and cut off her access to other commissions. In the name of protecting against abuses, are we not risking the loss of what has been a key advantage of the Polish labour market?

Equal treatment in length of service – symbolic justice or practical chaos?

From 2026, periods spent running a business and working under contracts for specific tasks will be counted towards length of service. At first glance, this is a long-awaited gesture of fairness – at last, every form of legal professional activity counts. However, updating B2B contracts for 2026 and adapting HR systems to these changes is a challenge whose scale is underestimated by both legislators and some experts.

An employee with five years’ experience on B2B contracts suddenly becomes entitled to longer annual leave, a higher severance payment or a longer notice period – even if they have been a ‘freelancer’ up to now. Employers, particularly in the private sector, must quickly review their procedures, update their data and prepare for claims. In practice, this amounts to an avalanche of administrative tasks, which could hit smaller firms particularly hard.

New obligations for businesses – is flexibility no longer worth it?

The obligations of B2B businesses in 2026 will extend far beyond the mere terms of the contract. Whether a working relationship is genuinely based on partnership and independence will be assessed on the basis of facts, not declarations. The introduction of the possibility for the National Labour Inspectorate (PIP) to reclassify contracts immediately is forcing companies to conduct a thorough audit of all B2B relationships. Bringing B2B contracts into line with the 2026 requirements demands not only changes to the wording, but above all a change in practice: a clear separation of work tools, autonomy in carrying out tasks, and the absence of organisational subordination.

At the same time, there is a tax risk: reclassifying a B2B arrangement as a permanent employment contract entails not only outstanding social security contributions and personal income tax advances, but also a potential problem with VAT settlement – so-called ‘empty invoices’ may result in both parties losing their right to deduct tax. Consequently, what was intended to be a tool for tightening up the system may become a source of unpredictable costs and disputes.

Changes to B2B contracts in 2026 present businesses with a dilemma: should they stick with flexible forms of collaboration and risk sudden reclassification by the National Labour Inspectorate (PIP), or switch to permanent employment and lose the competitive advantage derived from flexibility? In sectors reliant on project-based work and rapid responses to market changes, the rigidity of permanent employment may prove to be an insurmountable barrier.

For example, a small creative agency which has hitherto employed graphic designers and copywriters on a B2B basis suddenly has to recruit HR and payroll specialists, implement procedures familiar from large corporations, and come to terms with rising labour costs. On the other hand, ignoring new regulations carries the risk of severe penalties and disputes with state authorities.

The hidden truth – not all flexibility is a problem

The greatest paradox of the new regulations lies in the assumption that flexibility always amounts to abuse. Meanwhile, for years the Polish labour market has served as a testing ground for innovative models of collaboration, enabling companies and professionals to adapt quickly to change. B2B contracts and the 2026 Act are not only about combating abuse, but also carry the risk of losing competitive advantages to more rigid Western models.

Statistics show that the proportion of abuses in civil law contracts is falling steadily. In 2024, PIP inspectors classified only 3.6 per cent of the contracts inspected as fictitious. This means that the majority of business owners and the self-employed use these arrangements in good faith – for mutual benefit.

What will happen to the Polish labour market after 2026?

Changes to B2B contracts in 2026 could trigger a profound transformation. Some companies will opt for a full transition to permanent employment, whilst others will seek new, more sophisticated models of collaboration or relocate their operations to countries with less restrictive regulations. Micro-entrepreneurs, who lack the legal or accounting resources to adapt quickly to the new realities, may suffer the most.

For specialists who have hitherto relied on B2B as a tool for growth and independence, the spectre of losing control over their own careers looms large. Employers who have so far built their competitive edge on flexibility must now reckon with higher costs and greater uncertainty.

Is a compromise between protection and freedom possible?

The changes to B2B contracts in 2026 are not merely a matter of labour law – they are a test of the market’s maturity and its ability to distinguish between abuse and genuine entrepreneurship. The real challenge lies in striking a balance: protecting those who are forced into self-employment must not lead to penalising those who consciously choose flexibility.

Perhaps the future lies in a more nuanced approach: rather than automatic responses and suspicion, it is worth focusing on education, clear criteria and dialogue between market participants. The adaptation of B2B 2026 contracts will only be effective if it becomes a collaborative process, rather than a unilateral enforcement of new regulations. Otherwise, the Polish labour market risks losing what has been its greatest strength for years – the ability to adapt quickly and collaborate creatively.

This is precisely why the discussion on the B2B 2026 legal changes should go beyond simplistic frameworks. It is not merely a matter of ‘complying with the regulations’, but a debate about what sort of Poland – as a place to work and do business – we want to build after 2026.

Frequently asked questions

When exactly will the changes to B2B contracts come into force, and which companies will they affect?

The changes concerning B2B contracts and the inclusion of business activities and civil law contracts in the calculation of length of service will come into force on 1 January 2026 for the public sector. In the private sector, the new regulations will come into force on the first day of the month following the expiry of a six-month period from the date of the Act’s promulgation.

Will every B2B contract be automatically reclassified as a permanent position?

No, the changes do not mean that all B2B contracts will automatically be reclassified as employment contracts. However, the new powers granted to the National Labour Inspectorate (PIP) allow inspectors to assess independently whether a given working arrangement meets the criteria for an employment relationship. In such cases, the PIP may issue a decision to convert a B2B contract into a permanent employment contract, even without the consent of the parties.

What are the key criteria the PIP will use to assess B2B contracts?

The PIP will analyse whether, in practice, the working arrangement has the characteristics of an employment relationship, i.e. including subordination to the employer, performing work at a specified place and time, and performing the work in person. The actual conditions under which the work is carried out will be key, rather than merely the provisions of the contract.

What are the potential consequences for a company if a B2B contract is deemed to be an employment relationship?

If a B2B contract is deemed to be an employment relationship, the company must immediately treat the contractor as a permanent employee, with all the resulting obligations. This may mean having to pay outstanding social security contributions and income tax, as well as ensuring that the contractor is granted employee rights, such as annual leave and a notice period. A decision by the National Labour Inspectorate (PIP) is immediately enforceable, even if an appeal is lodged.

Will the period of work under B2B contracts count towards length of service, and what benefits does this bring?

Yes, from 2026, periods spent running a business and working under contracts of mandate and B2B contracts will count towards length of service. This will, amongst other things, allow employees to claim longer annual leave, a higher severance payment or a longer notice period, even if part of their professional career was spent outside of permanent employment.

How do you document previous periods of work under a B2B contract or a contract for specific tasks?

The primary document confirming these periods will be a certificate from ZUS regarding paid contributions. If ZUS does not have complete records, other documents may be submitted, such as contracts, invoices, bank transfer confirmations or certificates from clients. Employees have 24 months from the date the Act comes into force to provide these documents to their employer.

Do these changes mean the end of self-employment in Poland?

No, the aim of the new regulations is not to abolish self-employment, but to eliminate abuses involving bogus self-employment. Properly drawn up B2B contracts, based on genuine business cooperation, will continue to be permitted and legal.
