Polish Investment Zone: tax relief for foreign investors in Poland

Legal position: 9 October 2026

Before your group approves a factory, a new production line or a service operation in Poland, you need to know whether the tax incentive fits the business case. A headline aid percentage is only part of the answer. The Polish entity must qualify, the investment must follow the right sequence, and the activity must generate income eligible for exemption.

Polish Investment Zone: the short answer

The Polish Investment Zone (Polska Strefa Inwestycji, PSI) allows a qualifying business to use a Polish income-tax exemption under a decision on support (decyzja o wsparciu). For a company, this normally means corporate income tax (CIT). Foreign ownership does not, by itself, exclude a Polish company. Relief is conditional, capped and linked to the activity and site specified in the decision; it is not an upfront cash grant or an exemption from every Polish tax.

Check the Polish investment before you commit

Can a foreign-owned company qualify?

The starting point is the business carrying out the investment in Poland, rather than the nationality of its shareholders. A Polish subsidiary of an international group may qualify if its project and activity meet the rules. Simply selling goods into Poland from abroad does not establish eligibility.

A new establishment, an increase in production capacity, a qualifying diversification or a fundamental production-process change can fall within the definition of a new investment. An ordinary replacement purchase, a share acquisition or a distribution business should not be assumed to qualify. Certain service investments can be considered, but the actual activity and its Polish classification, PKWiU, must be checked against exclusions.

For a market-entry project, identify who will own or use the assets, employ the team, carry out the supported activity and earn the relevant income. A company-registration plan and a tax-incentive plan need to fit together.

Location and group size change the assessment

PSI is not restricted to buying land in one of the old special economic zones. However, support availability and intensity still depend on the exact location and the regional aid rules. Compare candidate sites before using one tax assumption across your Polish investment budget.

There are two core tests: a quantitative test concerning eligible expenditure and qualitative criteria concerning the investment’s contribution to economic and social development. Applicable thresholds and scoring vary. Select commitments the Polish team can deliver and document, rather than promises chosen only to obtain points.

A small Polish subsidiary is not automatically an SME. Under the EU definition, relevant staff and financial data of partner and linked enterprises must also be taken into account, including foreign group companies. A new company with a handful of employees may therefore be assessed as a large enterprise.

For large enterprises investing in Lower Silesia, Wielkopolska or the specified municipalities of the Warsaw metropolitan region, support is restricted to an initial investment that creates a new economic activity within the meaning of the regional aid rules. Merely expanding an existing establishment carrying on the same or a similar activity may therefore be insufficient.

Check the sequence before headquarters orders equipment

Start the PSI assessment before construction or a binding equipment order makes the project irreversible. The start-of-works test can be triggered before the first invoice is paid. A group purchasing team’s commitment relating to the Polish project needs to be reviewed alongside the subsidiary’s contracts.

Buying land, obtaining permits and carrying out feasibility studies are generally preparatory steps for this test. That does not mean every related cost will qualify. There are two separate questions: whether the aid application precedes the start of works, and whether expenditure meets the qualifying-cost rules and falls within the relevant period under the decision.

Submitting an application is not an award of support. Do not assume that expenditure incurred between application and decision is covered simply because the application was filed.

An aid ceiling is not the same as tax savings

In a simplified investment-cost model, the ceiling starts with eligible expenditure multiplied by the applicable aid intensity. The detailed calculation must also consider discounting, other aid for the same costs and, where relevant, large-investment rules. An advertised percentage should never be treated as a guaranteed cash return.

Hypothetical assumptionIllustrative result
PLN 10 million eligible costs; assumed 40% intensityPLN 4 million nominal aid ceiling
PLN 2 million eligible taxable income per year; assumed 19% CITPLN 380,000 tax saving per eligible year
Ten eligible years at that level of incomePLN 3.8 million before discounting, below the nominal ceiling

This is a teaching example, not a client result or a project forecast. The 40% intensity, 19% rate and ten eligible years are assumptions, not terms offered to every investor. Actual timing, discounting, income and decision conditions can change the result.

For current support decisions based on eligible investment costs, relief generally becomes available from the month in which the investment completion deadline specified in the decision expires. Exceptions and earlier decisions require a separate review.

For headquarters, model the ramp-up period, eligible Polish taxable income and the date relief can actually begin. Sales growth and group EBITDA do not establish the subsidiary’s exempt income. Intragroup pricing, royalties, services and financing should be consistent with the operating model; related transfer pricing issues merit a separate review.

A practical plan from screening to implementation

  1. Screen the project. Check activity, site, investment type, group status, progress, costs and available evidence. Identify any eligibility issue before the group commits.
  2. Build the application and financial case. Reconcile the investment schedule, realistic tax forecast and proposed obligations. Prepare the application for the competent area manager acting under the relevant authorisation.
  3. Implement and monitor the decision. Set up records for eligible income, costs, deadlines and the aid limit. Agree who in Poland and at headquarters will report changes.

The budget should include the mandatory paid services agreement with the area manager, as well as application, accounting and monitoring work. TLP can assist with the agreed stages; the scope should be set around the project’s actual needs.

What remains the Polish company’s responsibility?

The decision sets the supported activity, site, expenditure, completion deadline and other conditions. Investment, asset-retention and employment requirements must be monitored for the applicable periods. Relevant qualitative commitments also need evidence.

Accounting must distinguish the supported activity from activity outside the decision. If a group later changes the production model, sells assets, moves operations or restructures the subsidiary, check the effect before implementation. Failure to meet conditions can put the relief at risk and, depending on the circumstances, require repayment.

PSI does not settle VAT, customs duties, withholding tax or the parent company’s home-country treatment. Separate international tax questions belong in the group-level investment analysis.

Before the group commits: an investment checklist

  • Which Polish business will invest and earn the supported income?
  • What activity will it carry out, and is it excluded?
  • Which exact sites are being compared?
  • What is the enterprise’s size after applying EU group rules?
  • Has anyone signed a binding order or started construction?
  • Which costs and expenditure dates can qualify?
  • How much eligible taxable income is realistically expected?
  • Who will track commitments, other aid and later project changes?

Questions international investors ask

Can we apply before the Polish subsidiary is established?

Plan the sequence early, but the application must identify a qualifying investor. Establishing the company, transferring the project and contracting for assets raise separate timing and eligibility questions. Do not assume a parent company’s application will automatically cover a future subsidiary.

Is PSI only for manufacturing?

No. Some service investments can qualify. Eligibility depends on the specific activity, classification, investment and exclusions; calling a project a shared services centre or an IT hub is not enough.

Will the decision exempt all income of the Polish company?

No. Relief concerns eligible income from the activity and site covered by the decision, within its conditions and the available aid limit. The company needs a defensible method of identifying that income.

Can the parent company’s profits use the Polish aid limit?

Not merely because the parent owns the Polish business. The forecast must focus on the taxpayer and income covered by the Polish relief. The group’s wider tax position requires separate analysis.

Does a decision guarantee that the whole aid ceiling will be used?

No. Utilisation depends on eligible income, when exemption is available, the decision’s validity and ongoing compliance. A larger investment does not automatically produce a larger realised tax saving.

What if machinery has already been ordered?

Provide the order, contractual terms, dates and project history before assuming the project remains eligible. A binding commitment can matter even if delivery, payment and construction are still in the future.
