When You Can Use State Aid Under the Corporate Income Tax Exemption – Key Regulations and Pitfalls

Introduction: Legal framework and two support models

Businesses planning new investments within the Polish Investment Zone (PSI) on the basis of a support decision can benefit from an attractive CIT or PIT corporate income tax exemption. The legal basis for this mechanism is the Regulation of the Council of Ministers of 27 December 2022 on state aid granted to certain entrepreneurs for the implementation of new investments.

What matters for business practice is understanding that state aid under PSI can be granted in two fundamentally different models, which directly affects when the exemption can start to be used:

Model A – Support based on investment costs: The basis for calculating the maximum aid is expenditure on tangible fixed assets (buildings, machinery, equipment) and intangible assets (licences, patents, know-how). In this variant the corporate income tax exemption begins after the investment is completed.

Model B – Support based on labour costs: The basis is two-year labour costs related to the creation of new jobs as part of the new investment. Here the exemption can begin earlier – as soon as employment costs are incurred, regardless of the completion of the entire investment.

Misunderstanding these mechanisms leads to the most common errors: businesses use the exemption too early (before the investment is completed in Model A) or fail to exploit the full potential of the relief (in Model B). This article explains these issues in detail.

General rule: Exemption after completion of the investment (§ 9(1))

For support decisions based on investment costs (Model A), the fundamental rule set out in § 9(1) of the regulation applies:

„Support for the eligible costs of a new investment is available to the entrepreneur starting from the month in which the investment completion deadline specified in the support decision expired, until the support decision expires or the maximum permissible regional aid is exhausted, whichever event occurs first, subject to the exception referred to in § 5(6)."

What does this mean in practice?

The CIT/PIT exemption begins only from the month following the investment completion date indicated in the support decision. If the decision sets the completion deadline at 31 December 2026, the first month of using the exemption is January 2027.

Key consequences:

• Income earned before the investment completion date is fully taxable – even if the entrepreneur is already operating at the new facility, selling products and generating revenue.
• The investment completion date must be precisely specified in the application for a support decision – it is not an estimated date but a binding administrative deadline.
• Using the exemption prematurely (e.g. from the first month of operations, while the investment is still in progress) breaches the conditions of state aid and may result in the obligation to repay the relief improperly used, together with interest.

Exception: Exemption from labour costs (§ 5(6))

For support decisions based on the creation of new jobs (Model B), a different, more favourable rule set out in § 5(6) of the regulation applies:

„The income tax exemption referred to in paragraph 1, for the creation of new jobs in connection with a new investment, is available starting from the month in which the entrepreneur began incurring labour costs, until the maximum permissible regional aid is exhausted."

The fundamental difference

In this model the corporate income tax exemption begins from the month in which the entrepreneur actually started incurring the costs of employing new staff – regardless of whether the whole investment has already been completed.

Practical implications:

• If a company hires its first employees in July 2026 and the investment is completed only in December 2026, the CIT/PIT exemption may cover income already from July 2025.
• This model is particularly advantageous for labour-intensive investments (shared service centres, BPO, manufacturing requiring large headcount).
• Condition: The new jobs must actually be created and maintained for the required period (usually 3-5 years, depending on the size of the entrepreneur).

The importance of the investment completion date

Problem 1: Extension of the investment deadline

In business practice, delays in implementing investments are common: supply problems, design changes, administrative difficulties. If the actual completion of the investment takes place after the deadline specified in the support decision, the entrepreneur is caught in a trap:

• The tax exemption has formally already "started" (from the month after the original completion date),
• But the investment has not actually been completed, which may be grounds for the tax authorities to challenge the right to the relief.

Solution: The entrepreneur must promptly notify the change of the investment completion deadline to the minister responsible for the economy (currently the Minister of Development and Technology). This procedure requires:

1. Filing an application to amend the support decision,
2. Justifying the reasons for the delay,
3. Indicating a new, realistic completion date,

Without a formal amendment of the decision, income earned between the original and the actual completion date may be deemed not eligible for the exemption.

Problem 2: Accelerating the investment

Less often, but also possible, is completing the investment earlier than planned. Can the entrepreneur then start using the exemption earlier? Not automatically – in this case too, a formal amendment of the support decision with a new, earlier completion date is required.

Problem 3: Imprecise specification of the deadline in the application

Some entrepreneurs give overly optimistic or overly distant investment completion deadlines in their application for a support decision. Both situations are disadvantageous:

• Deadline too short – risk of delay and the need to amend the decision,
• Deadline too distant – unnecessary delay in starting to use the exemption and loss of potential tax benefits.

Recommendation: Realistic planning with a time buffer.

The most frequently overlooked pitfall

The corporate income tax exemption applies exclusively to income from the business activity specified in the support decision. This limitation, although obvious in theory, leads to serious problems in practice.

Case Study: The warehousing trap

Situation: The company "ProdukcjaPlus" Sp. z o.o. obtained a support decision for the production of electronic components. The application described the production process in detail but did not mention warehousing.

After a year of operations, a key customer demanded that the company store the manufactured components for 2-3 months before shipment (just-in-time delivery). The company agreed, charging an additional storage fee.

Problem: Warehousing/storage is a separate activity not covered by the support decision. Income from storage fees (even if it makes up a small percentage of total revenue) must be taxed at the full corporate income tax rate and is not eligible for the exemption.

Consequences: The company had to separate warehousing revenue and costs in its accounts, calculate the income from this activity and pay tax. In addition – there was a risk of a tax audit and an allegation of improper use of the exemption.

How to avoid this? The application for a support decision should have indicated the full scope of activity from the outset, including:

• Production (core),
• Warehousing of own products,
• Possibly: other activities from which income may be generated in the future.

How to use the exemption safely?

Step 1: Careful preparation of the application for a support decision

• Set a realistic investment completion deadline – with a buffer, but without excessive delay.
• Describe the full scope of planned activity – not only the main one but all ancillary ones (warehousing, call centre, etc.).
• Indicate all PKWiU codes from which income may be generated.
• Consult an adviser on the application  – it is an investment that will pay off.

Step 2: Monitoring investment progress

• Maintain a physical and financial schedule for the investment.
• 3-6 months before the planned completion, assess whether the deadline is realistic.
• If there is a risk of delay – start the procedure to amend the decision immediately; do not wait until the last moment.

Step 3: Formal completion of the investment

• Document the completion of the investment (acceptance protocols, occupancy permits, invoices).
• Report the completion to the authority that issued the decision (if the decision requires it).
• From the following month you can use the exemption (Model A) or continue the exemption begun earlier (Model B).

Step 4: Proper accounting records

• Separate in your accounts the revenue and costs of the exempt activity from other activity.
• Keep separate records for each support decision (if you have several).
• Document eligible costs (fixed assets, labour costs) – they will be the basis for settling state aid.

Step 5: Responding to changes

• Every material change (deadline, scope of activity, location, investment value) requires a formal amendment of the support decision.
• Do not use the exemption for activity not covered by the decision – it is better to pay tax on a small part of income than to risk losing the entire relief.
• Consult an expert on any doubts – the cost of consultation is incomparably lower than the risk of losing the exemption.

The exemption is a benefit, but it requires discipline

The corporate income tax exemption under state aid for new investments is one of the most attractive tools for supporting business development in Poland. It can mean savings counted in millions of zlotys. However, the condition for using it effectively is precision, planning and compliance with procedures.

Key risks to remember:

• Premature use of the exemption (before the investment is completed in Model A),
• Failure to respond to delays in implementing the investment,
• Using the exemption for activity not covered by the decision,
• Improper accounting records – failure to separate income.

When to consult an expert?

• Before filing an application for a support decision – this is the key moment,
• When delays or changes in the implementation of the investment arise,
• When you plan to expand the activity covered by the decision,
• Before any tax audit – preparation of documentation.

State aid is a powerful tool, but it requires a professional approach. Investing in advisory services at the planning stage pays off many times over by avoiding costly mistakes and making full use of the available reliefs.
