Estonia made development projects easier to implement and expanded access to large-scale investment support. At the same time, new EU AI transparency and packaging requirements began to apply. The August changes matter most for investment decisions in three areas: project financing, permitting and construction timelines, and product or service compliance. Legal preparation should begin before binding investment or supply contracts are signed.
This edition of RegRally covers the period from 1 to 31 August 2026 and is written for businesses and international investors operating or investing in Estonia.
This month at a glance
- Investment support: the general threshold for large-scale investment support was lowered from EUR 100 million to EUR 70 million, with EUR 35 million for priority technology projects and EUR 20 million for defense industry projects, and the job creation requirement reduced from 30 to 20. The amendment entered into force on 8 August. The grant cap is EUR 20 million per project, and supported activities must not begin before the application is submitted.
- Construction: the Building Code reform took effect on 1 August. Building notice validity was extended from two to four years, one use permit can cover several buildings, and a use notice replaces the use permit for one- and two-apartment dwellings. Requirements became stricter for certain alterations of residential buildings with three or more apartments.
- AI Act: Article 50 transparency obligations apply from 2 August. The AI Omnibus moved the high-risk deadlines to 2 December 2027 (Annex III) and 2 August 2028 (Annex I), and systems placed on the market before 2 August 2026 must meet the Article 50(2) marking requirements from 2 December 2026.
- Packaging: the EU Packaging and Packaging Waste Regulation entered general application on 12 August, including limits on PFAS in food-contact packaging. Most recyclability, labeling and reuse requirements follow in later stages, predominantly from 2028 or 2030.
- Electricity: from 1 August, consumption points with a bidirectional meter are billed on 15-minute net quantities, which changes the economics of on-site generation.
- From 1 September: online traders must offer consumers a clearly visible withdrawal button. The Consumer Protection and Technical Regulatory Authority flagged this at the end of August as an immediate preparation item.

Large-scale investment support expanded
Date: 8 August 2026 | Source: Minister of Economic Affairs and Industry Regulation No. 25, Riigi Teataja
Link
What happened?
Minister of Economic Affairs and Industry Regulation No. 25 of 3 August 2026 amended the conditions for large-scale investment support. The amendment was published on 5 August (RT I, 05.08.2026, 1) and entered into force on 8 August.
Estonia’s large-scale investment support thresholds after the August 2026 amendment:
- General investment threshold: lowered from EUR 100 million to EUR 70 million
- Priority technology projects: EUR 35 million, where previously the general EUR 100 million threshold applied
- Defense industry projects: EUR 20 million, where previously the general EUR 100 million threshold applied
- Jobs to be created: at least 20, down from at least 30
The thresholds concern eligible project costs. An applicant must be registered in the Estonian Commercial Register, and may be an Estonian company owned by a foreign investor. Priority projects include strategic digital and net-zero technologies, deep and biotechnology, and food and beverage production.
The grant cap is EUR 20 million per project. The standard maximum intensity is 10%. Up to 15% may apply outside Harju County, the region around Tallinn, where the average gross salary for newly created jobs exceeds 1.5 times the benchmark referred to in the regulation. Location outside Harju alone does not qualify a project for 15%. Applicable State aid ceilings must also be checked.
Supported project activities must not begin, and commitments for their implementation must not be undertaken, before the application is submitted. Pre-consultation and pre-assessment with the Estonian Business and Innovation Agency (EIS) must be completed before applying. A binding order or investment commitment may therefore jeopardize eligibility even if construction or equipment delivery has not yet started.
Why does it matter for businesses and investors?
Lower thresholds make Estonia a realistic candidate for medium-sized international industrial projects as well. Grant eligibility, site rights and the order of contract signing should be integrated into one investment plan.
Recommended actions
Businesses considering an application should:
- verify eligible costs, salary conditions and the timing of commitments before applying
- complete EIS pre-consultation and pre-assessment before submitting the application
- not begin supported activities or undertake binding commitments, including orders, before the application is submitted
- check the applicable State aid ceilings

Construction procedures became more flexible
Date: 1 August 2026 | Source: Act amending the Building Code and related legislation (RT I, 11.07.2026, 3)
Link
What happened?
The Act amending the Building Code and related legislation reduced procedural burden in several situations. The changes affect both new developments and the reconstruction and regularization of existing buildings, as set out in the Ministry of Climate explanation.
What changed on 1 August 2026:
- Building notice validity: extended from two to four years, so there is less need to repeat proceedings if construction is delayed
- Design conditions (projekteerimistingimused): their use was expanded, and where permitted, the solution can be refined without amending the detailed plan
- Use permits: a single use-permit application can cover several buildings in the same project, so they can be commissioned together
- One- and two-apartment dwellings: the use permit was replaced by a use notice
- Small non-residential buildings and selected structures: requirements were eased, with the procedure depending on the structure’s size, type and intended use
The reform is not a blanket simplification of all construction works. Requirements for a building permit became stricter for certain alterations and extensions of residential buildings with three or more apartments. Project schedules should therefore be based on the procedure applicable to the specific activity, not on the reform’s general purpose.
For buildings constructed before 1 July 2015, regularization continues to focus on safety. Buildings constructed before 22 July 1995 are treated as lawful. The EUR 500 state fee for registering a previously unregistered building was abolished. The publication of personal data in the Building Register was also clarified: personal data may be disclosed only where necessary for the proceedings or to demonstrate compliance.
Why does it matter for businesses and investors?
The four-year building notice validity gives developers more time to start construction after the notice has been submitted. This can reduce the need to repeat the procedure where a project is delayed.
When acquiring real estate, compare the physical situation with registry data, permits and planning instruments. Simplified procedures may help remedy defects, but the purchase agreement must still allocate responsibility, remediation duties and deadlines clearly. The availability of design conditions does not automatically guarantee the desired development rights.
Recommended actions
Developers and buyers should:
- base project schedules on the procedure applicable to the specific activity
- check whether previously unregistered buildings can now be registered, as the EUR 500 state fee was abolished

AI transparency obligations began to apply
Date: 2 August 2026 | Source: Regulation (EU) 2024/1689 (AI Act), European Commission
Link
What happened?
Article 50 of the EU Artificial Intelligence Act applies to certain providers and deployers of AI systems. It is relevant to customer-service chatbots, AI-enabled software, and synthetic marketing or media content.
Who has to do what under Article 50:
- Provider of an AI system interacting directly with people: ensure the person is informed that they are interacting with AI, unless this is obvious from the circumstances
- Provider of a system generating synthetic content: ensure machine-readable marking and detectability of AI origin to the applicable extent
- Deployer of a deepfake system: disclose that content was artificially generated or altered, subject to statutory exceptions
- Deployer publishing AI text on a matter of public interest: observe the disclosure duty and the human-review or editorial-control exception
The European Commission’s guidance helps define roles, exceptions and practical compliance methods. Neither the guidance nor the voluntary code of practice replaces the obligations laid down in the Regulation.
The AI Omnibus, which entered into force on 27 July 2026, changed the implementation calendar for high-risk systems. Requirements under Annex III of the AI Act apply from 2 December 2027. Requirements for high-risk systems integrated into regulated products under Annex I apply from 2 August 2028. It is therefore inaccurate to say that all high-risk AI requirements applied from 2 August 2026.
Article 50 has its own narrow transition rule. For providers of systems placed on the market before 2 August 2026, the marking and detectability requirements under Article 50(2) must be met from 2 December 2026. This is not a general four-month extension covering all transparency obligations.
Why does it matter for businesses and investors?
An AI-using business should identify its role for each solution, verify user-facing notices, and agree with its supplier on content marking and the delivery of compliance information. In a technology acquisition, this review should form part of legal due diligence.
A business does not need to build AI to be affected. The duty follows from how a bought chatbot, drafting tool or content generator is used, and a company can be a deployer for one system and a provider for another. The contract should clearly allocate responsibility for marking, detectability and the information needed to demonstrate compliance.
Recommended actions
Businesses using or acquiring AI systems should:
- identify whether each relevant system makes the business a provider or a deployer and which Article 50 obligations apply
- review user-facing notices, marking and labeling arrangements, including the 2 December 2026 transition for systems placed on the market before 2 August 2026
- allocate compliance responsibilities and access to the required evidence in supplier and technology agreements
New EU packaging rules started to apply
Date: 12 August 2026 | Source: Regulation (EU) 2025/40 (PPWR), European Commission
Link
What happened?
The new Packaging and Packaging Waste Regulation entered general application on 12 August. It affects packaging manufacturers, importers, food businesses, retailers and e-commerce operators.
One requirement applies already in August. Food-contact packaging may not be placed on the market where its content of per- and polyfluoroalkyl substances (PFAS), the group of persistent chemicals used for grease and water resistance, exceeds the applicable limits. Businesses must be able to assess and demonstrate packaging compliance.
According to the Commission’s implementation guidance, having produced stock before 12 August does not, by itself, allow packaging that fails the PFAS requirements to be placed on the market later. The production date and the first placing on the market must be distinguished. Packaging placed on the market before 12 August may remain there under the guidance and does not have to be recalled solely because of the new PFAS restriction.
The PPWR did not apply all of its objectives at once in August. Harmonized sorting labels and several recyclability, recycled-plastic, empty-space and reuse requirements take effect in later stages, predominantly from 2028 or 2030, subject to the specific deadlines of each provision.
Why does it matter for businesses and investors?
The restriction applies at the first placing on the market.
Check packaging composition evidence, supplier confirmations and the timing of placing existing stock on the market. Supply agreements should address compliance documents, packaging replacement and cost allocation. A harmonized EU framework may support investment in compliant packaging and circular-economy solutions.
Recommended actions
Businesses placing packaged goods on the market should:
- distinguish production dates from the first placing on the market when managing existing stock
- map which later PPWR requirements, predominantly from 2028 and 2030, affect the product range
Electricity billing moves to 15-minute netting
Date: 1 August 2026 | Source: Electricity Market Act amendment, Elektrilevi
Link
What happened?
At consumption points with a bidirectional meter, grid and electricity bills are based on the difference between electricity taken from and fed into the grid during each 15-minute trading period. For example, 4 kWh taken from the grid and 3 kWh fed into it result in net consumption of 1 kWh for that period. This is not monthly or annual netting.
Why does it matter for businesses and investors?
The effect depends on the timing overlap between generation and consumption, so identical savings cannot be assumed for every producer. For businesses with on-site generation, the new methodology feeds directly into project economics.
Recommended actions
Businesses with on-site generation should:
- check their August billing under the new methodology
- update project economics using actual 15-minute data rather than monthly totals

E-commerce withdrawal button required from 1 September
Date: 1 September 2026 | Source: Consumer Protection and Technical Regulatory Authority (TTJA)
Link
What happened?
From 1 September 2026, an online trader must enable consumers to submit a withdrawal statement through a clearly visible withdrawal button or an equivalent function. The Consumer Protection and Technical Regulatory Authority highlighted the need to prepare for this at the end of August.
The solution must allow the consumer and the contract to be identified, confirm submission of the withdrawal statement, and immediately send an acknowledgement on a durable medium stating the content and time of submission.
Why does it matter for businesses and investors?
The requirement covers more than the button itself: identification, confirmation and the durable-medium acknowledgement all have to work end to end.
Recommended actions
Online traders should:
- implement the withdrawal button or an equivalent clearly visible function
- ensure the solution identifies the consumer and the contract, confirms submission, and immediately sends an acknowledgement on a durable medium with the content and time of submission
- test the entire workflow from button to acknowledgement, on a real order

What international investors should take from August
The strongest combined effect of the August changes is on industrial and technology investments: a lower support threshold may improve financing, the construction reform may facilitate delivery, and the new electricity methodology may change the economics of on-site generation. The impact must be assessed project by project.
Large-scale investment support does not replace foreign investment clearance. Under the existing framework, an investor from a third country may require clearance for an investment in a designated target undertaking, and a company established in the EU but controlled by a third-country person may also qualify as a foreign investor. The regime covers, among other things, the acquisition of significant participation or control and certain asset transactions. This is an existing framework, not a new August requirement.
Four checks for management:
- Investment project: verify eligible costs, salary conditions and the timing of commitments before applying
- Real estate: update the permit schedule and check consistency between the physical building and registry documents
- AI and packaging: assign responsibility, identify applicable requirements and collect supplier evidence
- Energy and e-commerce: verify the new billing method and the actual operation of the withdrawal function
