Draft amendments to the Act on Supporting New Investments – what foreign investors should know
| Legislative status – as of June 2026
This guide discusses a draft amendment to the Polish Act on Supporting New Investments. Its assumptions have been entered in the Government’s List of Legislative and Programme Work, and the proposed direction was presented publicly in June 2026. These are proposed, not binding, rules. The final shape of the legislation – and indeed whether it enters into force at all – depends on the course of the legislative process. Until the act is promulgated in the Journal of Laws, the current legal framework described below remains in force. |
Why this matters for foreign investors
For an inbound investor, the Polish Investment Zone (PSI) is the single most important tax incentive in the country: a corporate or personal income tax exemption granted by a so-called decision on support, in exchange for carrying out a qualifying investment of a defined value and creating a declared number of jobs. Unlike the earlier special economic zone (SEZ) model, the PSI exemption is available across the entire territory of Poland rather than within demarcated areas only.
In June 2026 the government outlined a broad amendment to the regime. Three features make it directly relevant to capital allocation decisions. First, the maximum period of the support decision is to be extended, lengthening the horizon over which the exemption can be used. Second, that extension interacts with the global minimum tax, potentially preserving the real value of the incentive for multinational groups. Third, a new mandatory tax-authority opinion will apply to the largest projects, adding a procedural step that must be planned for. The remainder of this guide explains the current regime, then walks through what is set to change.
The PSI in brief – the regime as it stands
Support for a new investment is granted, under Article 3 of the Act on Supporting New Investments of 10 May 2018 (consolidated text: Journal of Laws of 2023, item 74, as amended), in the form of an income tax exemption. For corporate taxpayers the legal basis is Article 17(1)(34a) of the CIT Act; for individuals carrying on business activity, Article 21(1)(63b) of the PIT Act. The exemption covers income from the business activity specified in the support decision, carried out within the area indicated in that decision, up to the ceiling of available State aid.
Support decisions are issued, on behalf of the minister responsible for the economy, by the area manager – historically the companies managing the special economic zones. Today a decision runs for ten, twelve or fifteen years, depending on the regional aid intensity applicable to the location. The amount of aid is calculated as the product of the maximum aid intensity for the region and either the eligible costs of the new investment or the two-year labour costs of newly employed staff.
The instrument has a strong track record. Between September 2018 and 31 December 2025, roughly 3,700 support decisions were issued, covering a declared investment value of around PLN 154.4 billion and close to 55,570 new jobs. Polish small and medium-sized enterprises accounted for about 72 percent of the projects, confirming that the regime reaches well beyond large multinationals.
What the draft changes
Extension of the support-decision period and the global minimum tax
The most consequential proposal is to extend the maximum period of a support decision to twenty years, against the current ceiling of fifteen. A longer horizon increases certainty across the full life cycle of an investment and helps absorb capital outlays in long-payback projects typical of manufacturing and logistics.
The extension carries particular weight under the OECD Pillar Two global minimum tax (the top-up tax, implemented in part through the QDMTT mechanism). The structure of that levy can mean that benefiting from PSI-style exemptions triggers a top-up tax payable outside Poland by international groups. Spreading the same support over a longer period lowers its annual intensity and may therefore soften the top-up effect, helping to preserve the real value of the incentive for groups within scope of minimum taxation. For multinational investors, this is the change most likely to alter the post-tax economics of a Polish project.
A mandatory opinion from the Head of the National Revenue Administration
A genuinely new feature is an opinion issued by the Head of the National Revenue Administration (KAS) on a new investment. The opinion is to address the subject matter of the business activity connected with the investment and the area where it is to be carried out, to the extent these bear on the scope of the tax exemption. Under the assumptions, the opinion will be mandatory where the maximum permissible amount of State aid for an investor is to exceed PLN 25 million.
The mechanism strengthens fiscal oversight before a decision is issued and, in the drafters’ intention, gives the taxpayer certainty as to how the exempt activity and its location will be understood. In practice it adds a procedural stage to large projects. Investors should build this step into their timelines and ensure that the description of the activity and the investment area is consistent across the application, the project documentation and the transfer pricing policy – consistency that matters most where the Polish entity performs functions for related parties within a group.
Express treatment of reinvestments
The draft expressly confirms the right to exempt income generated by the expansion of existing plants – so-called reinvestments. The eligibility of reinvestments has, to date, raised interpretive doubts, even though reinvestments feature in roughly 70 percent of the support decisions issued. A statutory confirmation materially improves the tax certainty of businesses scaling capacity within facilities that are already operating.
Digitalisation through the ePSI platform
The draft provides for an Electronic Platform of the Polish Investment Zone, operating under the working name ePSI. It is to allow applications, correspondence with the authority and the issuing, amendment and expiry of decisions to be handled electronically. The system is also expected to verify simple formal errors automatically – a frequent cause of delay to date – and to support monitoring of the effects of granted support. For investors running parallel projects across several locations, the resulting standardisation of documentary requirements is a practical benefit.
A new definition of the employment level
The draft introduces a new definition of the employment level. To date the concept has been read – including in the case law of the Supreme Administrative Court – not only as a headcount but also in temporal terms, as an average workforce maintained over a given period. The proposed provision is to state unambiguously that the employment level is the number of employees engaged at the establishment where the new investment is located. The change simplifies verification of the commitments under a support decision, but obliges investors to revisit how they declare and monitor employment, particularly in multi-site structures and where flexible forms of engagement are used.
Defining the area manager after the zones expire
The reform is prompted by the expiry of the Special Economic Zones Act of 20 October 1994, which ceases to have effect on 31 December 2026. On that date the existing area managers would lose their legal basis to act. The draft adds an autonomous definition of the area manager to the Act on Supporting New Investments and transfers to it the competences to service investors and to issue, amend and monitor support decisions – securing institutional continuity for investors after the zones are wound down.
Foreign investor considerations
On balance, the proposed changes are favourable to inbound investors. The longer decision period and its link to the global minimum tax address one of the principal tax risks faced by multinational groups using Polish incentives, while digitalisation and the express treatment of reinvestments improve the predictability of the investment process.
At the same time, the mandatory KAS opinion for projects with aid exceeding PLN 25 million means that the largest foreign investments will undergo additional, prior scrutiny by the revenue administration. This step should be reflected in project timelines, and the description of the activity and investment area should be coherent across all documentation. Investors should also recall that zone-exempt income is subject to separate accounting from other preferences – including the R&D relief and the IP Box – requiring careful segregation of the costs and revenues of exempt and taxable activity. The reform does not change this principle; it tidies the regulatory environment in which it operates.
Current regime versus proposed rules – at a glance
The table below contrasts the key elements of the instrument as it stands with the shape suggested by the draft assumptions. The right-hand column should be read subject to its non-binding, draft character.
| Area | Current regime | Proposed rule |
| Application process | Paper / mixed, fragmented | Electronic ePSI platform, automated error checks |
| Support-decision period | 10, 12 or 15 years | Extended up to 20 years |
| Global minimum tax | No mitigation of effect | Longer period lowers annual aid intensity |
| Employment level | Headcount-and-time reading (case law) | Headcount at the investment establishment |
| Fiscal oversight | No prior KAS opinion | Mandatory KAS opinion where aid > PLN 25m |
| Reinvestments | Eligibility uncertain | Right to exemption stated expressly |
| Area manager | Based on the SEZ Act | Autonomous definition in the WNI Act |
Timeline and entry into force
Under the assumptions, the draft is to be adopted by the Council of Ministers in the second or third quarter of 2026. Allowing for the usual course of the legislative process, the tax measures could apply to income tax settlements for periods beginning on or after 1 January 2027, while non-tax elements – including the operational aspects of the ePSI platform and the provisions regularising the status of area managers – could enter into force earlier.
These are projections based on published assumptions. The full text of the draft, its final wording and the effective dates of individual measures remain dependent on further legislative work. Investors planning to apply for support decisions in 2026 should monitor the progress of the work and factor in the possibility that the rules change while a procedure is pending.
Conclusions and practical recommendations
The proposed PSI reform points in an investor-friendly direction: it digitalises and accelerates the procedure, lengthens the horizon of the exemption, eases the tension between zone aid and the global minimum tax, and removes a significant interpretive doubt around reinvestments. In parallel, it introduces a new oversight stage in the form of the mandatory KAS opinion for the largest projects.
Investors holding a support decision, or planning new projects, should already assess the impact of the proposed changes on their strategy – in particular the time horizon of the investment, the way employment is declared, and the consistency of the documentation that determines the scope of the exemption. Decisions to commence or pause application proceedings in 2026 are best taken in light of the current state of legislative work, with the risk of change in mind. Given the draft character of the measures discussed, we recommend verifying the legal position immediately before any investment decision.
| Editorial note
This guide reflects the amendment assumptions known as of June 2026 and deliberately omits details whose wording has not yet been finalised – including the precise scope of transitional rules for decisions issued before the reform takes effect, the technical parameters of the ePSI platform, and any regional differentiation of the maximum decision period. It also does not cover the detailed rules for calculating the State aid ceiling, the regional aid intensity applicable in individual voivodeships, or the interaction between the zone exemption and the R&D relief and IP Box, all of which call for separate, case-specific analysis.
