Can an expenditure that was not specified in the business plan or in the application for an investment support decision be treated as an eligible cost?

This is one of those questions that arises with considerable frequency in the course of implementing investments covered by an investment support decision: can an expenditure that was not specified in the business plan or in the application for an investment support decision be treated as an eligible cost?

In my view, the answer is, as a general rule, yes.

But as always in the Polish Investment Zone, the devil is in the detail.

A business plan is a plan – not a fixed investment blueprint

In practice, investments very rarely unfold exactly as described at the application stage. Market conditions shift, prices change, the availability of technology evolves, the entrepreneur’s operational requirements develop — and sometimes the very concept of the project only matures during the course of implementation.

Consider a straightforward scenario. A company plans an investment worth PLN 40 million. Under the original assumptions, half of the funds are to be allocated to the construction of a production facility and the other half to the acquisition of machinery. In the course of implementation, however, the entrepreneur concludes that it would be more economically rational to scale back the construction component and redirect a larger share of the budget towards the machinery pool.

Does this mean that the “additional” expenditure on machinery – not originally envisaged at that scale – automatically falls outside the scope of eligible costs?

In my assessment, no.

Not literal compliance, but a functional connection to the investment

The starting point should be that a business plan describes an investment intention – not a closed and immutable catalogue of all future expenditure.

Were one to adopt a strictly formalistic approach, one would have to conclude that any significant modification to the expenditure structure leads to the loss of eligibility for part of the costs incurred. Such an interpretation would, however, be detached from economic reality and would, in practice, render the investment process unnecessarily rigid.

What matters far more, therefore, is not whether a given expenditure was described in full detail in the business plan, but:

  • whether it falls within the statutory catalogue of eligible costs,
  • whether it is functionally connected to the investment being implemented,
  • and whether the modification does not alter the fundamental nature of the project.

It is precisely these criteria that should carry decisive weight.

When can additional expenditure qualify as eligible?

In practice, the assessment of such expenditure should be based on three core questions.

  1. Does the expenditure fall within the statutory catalogue of eligible costs? This is the threshold requirement. Alignment with the business logic of the project is insufficient in itself if the expenditure falls outside the framework established by the applicable regulations.
  2. Is the expenditure genuinely connected to the investment covered by the support decision? Functionality is the key consideration here. It is necessary to assess whether the expenditure serves the implementation of that specific investment, or whether it relates, in substance, to an entirely different project.
  3. Does the modification alter the nature of the investment? The Polish Investment Zone affords the entrepreneur a degree of flexibility, but this does not translate into unlimited latitude. If the modifications are so far-reaching that the project ceases to be the undertaking originally described in the application, a material risk arises.

If, however, the investment retains its fundamental character and the change in expenditure structure is underpinned by a sound business rationale, the mere absence of a given cost item from the business plan should not automatically render it ineligible.

Where does this practical caution originate?

Against this backdrop, it is worth drawing attention to the increasing level of detail recently observed in the documentation prepared in connection with investment support decisions – particularly with regard to the reasoning set out therein. This trend reflects measures taken by the Ministry of Economic Development and Technology aimed at harmonising the approach adopted by the individual management companies of special economic zones. The objective of these changes is, above all, to introduce order and standardisation in the documentation process – not to curtail investors’ flexibility in the course of project implementation.

The greater level of detail in the reasoning accompanying an investment support decision should not, however, be conflated with a complete rigidity of the investment itself.

The reasoning set out in an investment support decision is not conclusive in nature and does not constitute an independent source of obligations for the entrepreneur. The content of the reasoning and the business plan may, of course, play an important role in the assessment of a project, but they should not be treated as a closed and immutable catalogue of each and every expenditure that the entrepreneur may incur.

Were this not the case, the investment support decision would begin to function as a document that effectively “freezes” the investment — and yet economic reality looks quite different. This would also sit uneasily with the increasingly articulated policy objective of enhancing Poland’s investment attractiveness, particularly within the framework of the Polish Investment Zone.

What is the practical takeaway?

For this reason, what is of decisive importance is not so much the literal correspondence of the expenditures incurred with the original description of the investment, but rather their genuine connection to the project and their consistency with its core assumptions. From a practical standpoint, the critical question is whether the entrepreneur is able to demonstrate that the modification:

  • falls within the boundaries of the project covered by PSI support,
  • is underpinned by a sound business rationale,
  • does not undermine the fundamental assumptions of the investment,
  • and does not result in the creation of, in substance, an entirely new undertaking under the guise of the original one.

This approach seems to me consistent not only with the logic of the applicable regulations, but also with the underlying economic rationale of the Polish Investment Zone. After all, the purpose of this mechanism is to support genuine investments — not to require that every project be reproduced precisely as it was described at the planning stage.

Summary

Can an expenditure not specified in the business plan constitute an eligible cost under the Polish Investment Zone?

In my view, yes – provided that it falls within the catalogue of eligible costs, is functionally connected to the investment, and does not alter its fundamental character.

It is these elements that should be assessed in the first instance – not the mere fact that a given expenditure was not previously described in explicit terms or with a specific level of detail.

In practice, an investment is a process, not a static blueprint. And that is precisely why, in the context of the Polish Investment Zone, one should look not only at the document itself, but above all at the genuine purpose and overall coherence of the project as a whole.

I work with the standards that entrepreneurs know from the biggest consulting firms, but in a more direct, attentive, and flexible way.

I speak clearly, act with purpose, and do not create distance where trust and peace of mind are needed most.

An important part of my work is also operating in an international environment, including clear and business-focused communication with clients and business partners in German and English. I provide not only expert knowledge, but also something equally important: the feeling that someone is truly in control of a complex matter.

Because in demanding projects, clients do not only need a tax expert — they need a partner who can connect complex elements into one logical whole and give decisions the right direction.
