Estonia is an attractive country for companies due to its digital state infrastructure and simple corporate tax system. However, these advantages come with a quite technical framework of accounting and tax legislation, especially with the reforms in 2025–2026. Understanding topics such as Estonian GAAP, IFRS, distribution-based corporate tax, mandatory e-invoicing, and changing audit thresholds is critical for reducing tax risks and maintaining investor confidence.
General Framework of Accounting Legislation in Estonia
The foundation of accounting in Estonia is formed by the Accounting Act and its related secondary regulations. In practice, companies choose one of two main financial reporting standards:
- Estonian GAAP (Estonian Financial Reporting Standard)
- IFRS (full IFRS accepted by the EU)
The choice varies according to the size of the company, the area of activity, and the profile of investors:
- Full IFRS: Mandatory for banks, insurance companies, and other public interest entities.
- SMEs: Generally use Estonian GAAP. However, companies attracting international investors, having a group structure, or aiming to go public may opt for IFRS.
Both standards include the following items in the annual financial report:
- Balance sheet
- Profit/Loss statement
- Depending on the applied standard, cash flow statement and statement of changes in equity
- Notes to the financial statements
- Management report – a narrative section regarding the company’s activities, risks, and expectations
This structure is compliant with EU accounting directives and supports Estonia’s digital, data-driven tax audit approach.
Annual Reporting Obligations and Digital Infrastructure
Annual Report – Who, When, Where?
In Estonia, there is an obligation for all companies (OÜ, AS, branch, NGO, even dormant companies) to submit an annual report.
Basic rules:
- You must submit the report within 6 months following the end of the financial year.
- For companies whose financial year is the calendar year, the deadline is usually June 30.
- All reports are submitted completely digitally via the e-Business Register.
This digital system is compatible with the e-signature infrastructure and allows remote management for both residents and e-Residents. However, since the system easily detects incomplete or erroneous reports, the accuracy and timing of accounting data become more critical than ever.
Independent Audit and Limited Audit – 2025 Threshold Changes
Starting from 2025, Estonia has updated audit thresholds. This revision particularly affects medium-sized companies directly.
For mandatory independent audit, at least two of the following three criteria must be met for two consecutive accounting periods:
- Revenue: ≥ 5,000,000 €
- Total assets: ≥ 2,500,000 €
- Average number of employees: ≥ 50
Additionally, if only one of these indicators reaches three times (for example, revenue ≥ 15 million €), an audit becomes mandatory. For the number of employees, the threefold rule has an exception limit of 180.
Review (limited audit) has higher thresholds (for example; approximately 6 million € revenue, 3 million € assets, 72 employees) and details are explained in the audit threshold guides.
Moreover, many public limited companies (AS) may have mandatory audit obligations independent of size, depending on the area of activity and partnership structure. This difference should be considered when planning the company structure.
Estonia’s Corporate Tax System: Distribution-Based Model
When is Profit Taxed?
Estonia’s most well-known feature is that profits are taxed not when earned, but when distributed. That is:
- While the company’s annual profit accumulates on the balance sheet, corporate tax does not arise.
- Tax is calculated when profit is distributed in the form of dividends, hidden distributions, additional benefits, or certain types of expenses.
As of 2025:
- The standard corporate tax rate on distributed profits is 22%.
- Tax is calculated as 22/78 of the net distributed amount (grossing method).
- The previously applied 20% standard rate and 14/86 reduced rates have been removed.
- For credit institutions, the advance corporate income tax (bank levy) rate has increased from 14% to 18% as of January 1, 2025.
- There is still no advance corporate tax on retained earnings.
This model offers a strong cash flow advantage for companies that reinvest profits in the business. However, it is essential to remember that distributions lead to taxation when designing dividend policies, intra-group distributions, and executive payments.
How to Declare Distributed Profit?
- Profit distribution is declared using the e-Tax (e-MTA) system with the TSD form.
- The declaration and payment deadline is the 10th day of the month following the distribution.
- The TSD is a combined declaration that covers not only profit distribution but also employee incomes and social security liabilities.
This integrated structure requires continuous and consistent accounting records with tax declarations. Misclassified payments can lead to severe penalties on both corporate tax and payroll taxes.
VAT Regime and Changes in 2025–2026
VAT Registration Threshold and Rates
In Estonia, VAT is applied at every stage of the value chain and significant changes in both rates and reporting are taking place in the 2025–2026 period.
- VAT liability threshold: Annual 40,000 € taxable revenue.
- Standard VAT rate:
- January 1 – June 30, 2025: 22%
- Permanent rate from July 1, 2025: 24%
- The reduced rate for accommodation services has been increased from 9% to 13% as of January 1, 2025.
This increase in VAT rates directly affects pricing strategies, especially in tourism, hospitality, and retail sectors. It is essential to review the provisions regarding whether VAT is included/excluded in your contracts to prevent margin erosion.
VAT Declaration and Reporting Transformation
- The deadline for VAT declaration is the 20th day of the following month.
- As of 2025, preparations are underway to combine VAT declarations with EC Sales List (ESL) forms and transition from declaration-based systems to data-based reporting.
According to the new rules, when calculating the VAT registration threshold:
- Only revenue generated in Estonia is considered.
- Some transactions related to financial services, insurance, and real estate (except for exempt ones) are included in the threshold calculation.
The digitizing VAT audit allows for data comparison on an invoice basis, making it easier to quickly detect incorrect rate usage or misclassified transactions.
Other Important Tax Developments (2025–2026)
The 2025–2026 reform package is not only about corporate tax and VAT. There are significant innovations, especially for financial assets and individual investors.
- Regulated crypto assets: New regulations bring clearer rules for the taxation of licensed/exchange-traded crypto assets and a loss offset regime. This directly affects the reporting burden and tax planning for fintech and crypto-focused Estonian companies.
- Investment account system: The system that allows deferral of individual investment income has narrowed its scope; unlicensed small fund units have been excluded from the system as of 2025.
These areas are strategically important for tax compliance and investor relations in Estonian structures, especially for investors within and outside the EU.
Monthly and Annual Tax Declaration Calendar
TSD – Common Platform for Income, Social Security, and Distributed Profit
The Estonian tax system tends to combine multiple obligations into a single form. The TSD form is the most prominent example of this.
- Scope: Taxes calculated on employee incomes, social security contributions, and distributed profits.
- Declaration period: Monthly.
- Deadline: The 10th day of the month following the relevant period.
This structure necessitates integrated work between accounting and human resources teams in payroll and distribution processes. For Estonian companies sending personnel abroad under the posted worker model, it is critical to plan which payments are classified as payroll and which are considered profit distribution or additional benefits.
VAT, CbCR, and Other Notifications
- VAT declaration: Under KMD (and planned KMD+VD integration), by the 20th day of the following month.
- Country-by-Country Reporting (CbCR): Mandatory for international groups with consolidated revenue of €750 million or more.
- The report is usually submitted by the group’s parent company.
- The Estonian subsidiary must inform the Estonian tax authority who reports in which country.
- To avoid penalties, coordination between the group’s global tax team and the Estonian accounting team is essential.
The annual deadline for CbCR is usually December 31, but it may vary according to the group’s reporting calendar. It is necessary to create a calendar-based checklist to align group policies with Estonian obligations.
Electronic Invoicing Regime – From 2019 to 2025 Reform
Mandatory E-Invoicing in B2G Transactions
Since July 1, 2019, Estonia has made e-invoicing mandatory for all B2G (Business-to-Government) transactions. Public institutions only accept e-invoices, and these invoices are sent in the national XML standard or a format compliant with EN 16931.
This obligation is also included in the e-Invoicing country profiles prepared at the EU level, positioning Estonia as one of the leading countries in digitization.
After July 1, 2025: Common Regime for B2B + B2G
With the amendment of the Accounting Act, Estonia will transition to a single and standardized e-invoicing regime for B2B and B2G transactions starting July 1, 2025.
The foundation of the new system is the “buyer’s choice” principle:
- A buyer registered as an “e-invoice recipient” in the Commercial Register can only request e-invoices from their supplier.
- In this case, the seller cannot send paper or PDF invoices to that buyer; they must use the structured e-invoice format.
- The buyer can update their preference for receiving e-invoices at any time through the system, gradually promoting digitization throughout the supply chain.
This new regime significantly enhances data quality in VAT audits, providing serious protection against incorrect declarations and fraudulent invoices. However, the technical integration (ERP, accounting software, e-invoicing service provider selection, etc.) creates a need for additional investment and project management for companies.
The Importance of Estonian Legislation for International Structures, Posted Workers, and Payroll
The impact of legislation is even broader for companies established in Estonia that assign personnel within the EU, employ remote workers, or have an international group structure.
- Payroll management: Integrated declaration through TSD can lead to penalties for misclassified payments on both income tax and social security.
- Posted worker model: Sending temporary personnel from Estonia-based companies to other EU countries requires compliance with both Estonian legislation and the legislation of the host country. Poorly structured compensation packages can lead to double contributions and unnecessary tax burdens.
- Intra-group service and royalty payments: The distribution-based corporate tax system directly affects the pricing of intra-group transactions (transfer pricing) and profit distribution strategy.
Therefore, knowing only Estonian domestic legislation is often not sufficient. It is necessary to read Estonian rules in conjunction with tax, social security, and immigration legislation in the target country.
Corpenza Perspective: How to Navigate in a Digital, Distribution-Based, and Cross-Border Environment?
Estonia offers an ecosystem that provides both tax efficiency and operational flexibility when used correctly. However:
- Changing VAT rates with the 2025–2026 reforms,
- Rising audit and review thresholds,
- Expansion of e-invoicing obligation to the B2B sector,
- New tax rules in areas such as crypto assets and investment accounts,
require companies to redesign their accounting, tax, and legal compliance processes.
As Corpenza, we provide end-to-end support to companies, especially in the following areas:
- Company establishment and structuring in Estonia: Designing the choice of Estonian GAAP / IFRS, capital, and partnership structure with tax advantages in mind.
- International accounting and tax compliance: Solutions that align Estonia’s distribution-based corporate tax regime with group structure and other countries’ tax systems.
- Payroll, EOR, and posted worker models: Optimizing payroll, social security, and tax planning for Estonian-based employees and personnel assigned to other EU countries.
- Digital compliance projects: Establishing accounting infrastructure compatible with e-invoicing, e-Business Register, and e-Tax systems.
- Investment-based residency and citizenship structures: Designing the legal and tax framework for individuals and entities wishing to enter the EU market through an Estonian company.
Thus, we aim not only to ensure compliance with legislation but also to maximize the benefits of Estonia’s tax and digital infrastructure.
Conclusion: Accounting and Tax Management in Estonia After 2025
Estonia will continue to hold a unique position in Europe with its high level of digitization, modern accounting standards, and distribution-based corporate tax regime throughout 2025–2026.
However, this advantageous environment also comes with:
- Increasingly stringent audit and reporting obligations,
- Changes in VAT rates and thresholds,
- Mandatory e-invoicing transition in B2B and B2G,
- Pressure for international tax transparency (CbCR, data-based reporting)
It is necessary to plan these changes early with your accounting team or outsourced accountant; review financial statements, contracts, and tax strategies.
When making Estonia a part of your company formation, international expansion, posted worker, or investment-based residency/citizenship strategy, working with an experienced consultancy like Corpenza in international mobility and tax optimization significantly reduces potential risks and costs.
