Estonia ERP and accounting: e-invoices on request, 24% VAT

Estonian compliance in one view

Estonia runs one of Europe's most digital tax systems without a general e-invoicing mandate. Since 1 July 2025 any business registered as an e-invoice recipient can demand e-invoices from its suppliers, VAT is filed monthly with an invoice-level annex, payroll is declared on form TSD, and records are kept for seven years. It matters because customers, not the state, now decide when you must e-invoice.

Tax administration is national. The Estonian Tax and Customs Board (EMTA) runs VAT, income and social tax, excise and customs, and businesses file through the e-MTA portal or send returns machine-to-machine from their accounting software over X-tee, the state data exchange layer. The e-invoicing rules sit in the Accounting Act, maintained by the Ministry of Finance, and company data and annual reports go to the e-Business Register.

This page explains why Estonia chose the buyer's-choice model, how e-invoices move, every dated step as of September 2026, and what Skyline Nexus ERP does for an Estonian business.

• Tax authority: EMTA, through e-MTA and X-tee
• Currency: euro; standard VAT rate 24%
• E-invoicing: buyer's choice since 1 July 2025, EN 16931
• Accounts: Estonian financial reporting standard or IFRS
• Retention: source documents for seven years

Why Estonia chose e-invoices on request

Estonia made e-invoices compulsory for invoices to the public sector in 2019. In 2025 it replaced that rule with a broader principle: the buyer chooses the invoice format, and the right to demand an e-invoice extended from the public sector to the private sector. The aim is efficiency more than enforcement. An e-invoice is created digitally in a machine-readable file under a common standard, so it can pass from the seller's software into the buyer's for checking, approval and posting without retyping.

Enforcement comes from elsewhere. Monthly VAT returns carry the KMD INF annex, which lists invoices with each partner above 1,000 euro a month, so EMTA can compare what a seller declared with what the buyer deducted. That cross-check targets the VAT gap, the difference between the VAT a country should collect and what it actually collects, which the European Commission estimates every year for each member state.

Estonia's approach also prepares for the EU's VAT in the Digital Age package (ViDA). From 1 July 2030 EN 16931 e-invoices and digital reporting become the norm for intra-EU B2B supplies. The European Commission's country page notes that the Ministry of Finance has considered making e-invoices compulsory for all B2B transactions subject to VAT and removing the 1,000 euro threshold, but as of September 2026 no such change is in force.

How an Estonian e-invoice moves

A buyer that wants e-invoices registers publicly as an e-invoice recipient in the e-Business Register. From then on, its suppliers must send e-invoices on request. Delivery runs through e-invoice operators, which exchange invoices with each other under roaming agreements, so the seller and buyer do not need the same provider. The operators named by the Ministry of Finance include E-arveldaja, Telema, Billberry, Unifiedpost and Finbite; E-arveldaja, run by the state Centre of Registers and Information Systems, lets small businesses issue e-invoices at no cost.

The public sector continued its earlier practice, but the 2025 change also removed the old prohibition on public bodies accepting invoices in other forms, so they may now make exceptions. For cross-border trade, the Peppol network connects Estonian operators with access points across Europe.

Whatever the form, an invoice issued by a VAT-registered business must meet the content rules of section 37 of the VAT Act, and under the Accounting Act source documents must be in a form that allows written reproduction and machine processing. The Accounting Act sets no mandatory form for a source document; its main test is that a reader can understand the substance of the transaction.

• Right to demand: accounting entities registered as e-invoice recipients
• Standard: EN 16931 since July 2025; national standard by agreement
• Operators: E-arveldaja, Telema, Billberry, Unifiedpost, Finbite
• Cross-border: Peppol
• Invoice content: section 37 of the VAT Act

Deadlines: every dated step as of September 2026

The dates below come from the Ministry of Finance's e-invoice page, last updated in January 2026, EMTA's VAT pages and the European Commission's country page. They describe the position as of September 2026. There has been no postponement, because there is no general mandate to postpone; the date that applies to every business trading within the EU is 1 July 2030.

• 2019: e-invoices compulsory for invoices to the public sector
• 1 January 2025: income tax rate rises to 22%, and 22/78 for distributed profits
• 1 July 2025: buyer's choice principle; any registered accounting entity may demand e-invoices; EN 16931 becomes the standard
• 1 July 2025: standard VAT rate rises from 22% to 24%
• 20th of each month: KMD return, KMD INF annex and VD report for intra-EU supplies
• 10th of each month: form TSD for payroll taxes
• 1 July 2030: EU-wide e-invoicing and digital reporting for intra-EU B2B supplies under ViDA

VAT rates, registration and filing

Estonia has four VAT rates as of September 2026: 24% standard since 1 July 2025, 13% for accommodation and accommodation with breakfast, 9% for items such as press publications, and 0% for exports of goods and certain other supplies. The rise to 24% affected every standard-rated price list and contract, and rates must be applied by the date of supply.

A business must register for VAT once its taxable supplies exceed 40,000 euro from the beginning of the calendar year. The tax period is one calendar month, and the VAT return (KMD) and the report on intra-Community supplies (VD) are due by the 20th of the following month. They can be filed on e-MTA by hand or as an XML or CSV upload, or sent machine-to-machine through X-tee.

The KMD INF annex is where Estonian VAT is most demanding for systems. It declares sales and purchase invoices wherever the total without VAT per transaction partner is at least 1,000 euro in the month, so the ledger has to hold each invoice with the partner's registry code and invoice number, not just VAT totals.

• 24% standard rate since 1 July 2025
• 13% accommodation; 9% items such as press publications
• Registration above 40,000 euro of supplies in a calendar year
• KMD, KMD INF and VD: by the 20th of the following month

Accounting Act, annual reports and retention

Every legal person and every sole proprietor registered in the Commercial Register must keep accounts under the Accounting Act. The Act requires them to document all business transactions, record them by double entry on the basis of source documents, prepare and file annual reports, and keep source documents for seven years after the end of the financial year. Corrections are allowed, but they must be documented and traceable later, exactly like the original entry.

Annual reports are prepared under the Estonian financial reporting standard, issued through the Ministry of Finance's Accounting Standards Board, or under IFRS as adopted in the EU, which listed companies use. They are filed through the e-Business Register. Each business can also set its own rules on document formats and retention in its internal accounting rules, as the Act allows.

Estonia's corporate income tax works differently from most countries. Companies pay income tax only when profit is distributed, at 22/78 of the net distribution since 2025, so retained profit is not taxed. For bookkeeping, that makes dividends and other distributions the events that trigger tax, declared on form TSD.

Payroll: TSD, social tax and unemployment insurance

Employers declare income tax, social tax, unemployment insurance premiums and funded pension contributions on form TSD, a summary form with annexes, by the 10th of the month following the month in which salary was paid. Payments are made to EMTA by the same date.

The main rates are straightforward. Income tax is 22% since 2025, after the basic exemption. The employer pays social tax of 33% of gross salary and an unemployment insurance premium of 0.8%; the employee's unemployment insurance premium of 1.6% is withheld. Employees in the funded pension scheme contribute 2%, or 4% or 6% if they chose a higher rate, while the state directs 4 points of the 33% social tax to their pension.

For the ledger, that means a payroll journal each month with separate liabilities for income tax, social tax, unemployment insurance and pension contributions, reconciled to the TSD and to the payments made.

Cities and regions: where the rules differ

VAT, income tax, social tax and e-invoicing are national, so a business in Tallinn, Tartu, Narva, Pärnu, Kohtla-Järve, Viljandi, Rakvere, Maardu or Kuressaare works under the same rates, forms and deadlines. There is no regional e-invoicing regime and no regional VAT rate.

The only local differences are small. Municipalities set land tax rates within national limits and may levy local taxes such as an advertisement tax, so property and signage costs vary by location. For finance teams they are cost items to track by site rather than compliance regimes, which is why multi-site Estonian businesses mostly need location reporting for management, not for tax.

• Land tax and local taxes: set by municipalities
• VAT, TSD, e-invoicing: identical nationwide

How Skyline Nexus ERP handles Estonian requirements

Skyline Nexus ERP is a cloud ERP with a double-entry general ledger under Fiscal Authority. With the auto-post switches on, final sales, purchases, payments, expenses and depreciation post balanced journals in the background, and output VAT is computed per line on the same basis as the tax report, so 24%, 13% and 9% lines each post correctly. The VAT Return screen prefills tax-exclusive sales and purchase bases and VAT for a date range and location, ready for the KMD, and customer and supplier ledgers and statements give the per-partner totals behind the KMD INF annex.

The Accounting Act's traceability rule is built in: every automatic journal comes from a source document, posted journals are reversed rather than edited, sales returns are recorded as credit notes, fiscal periods can be soft-closed or locked, and the Accounting Audit Trail records who changed what, with old and new values. The Audit Pack exports a year's ledger, journals, sales, purchases and VAT summary to one Excel workbook for the seven-year archive, and the chart of accounts can be imported from CSV or Excel.

National e-invoicing connectors are being rolled out market by market, and Estonian EN 16931 e-invoicing through operators is part of that programme: tell us your country and we will confirm your go-live date. When a customer demands e-invoices before then, the working route is Skyline Nexus ERP alongside an Estonian e-invoice operator, with a partner-led integration reading sales and sales returns through the Skyline Nexus ERP Connector REST API. Estonian payroll and form TSD run in local payroll software or through a payroll partner, with the payroll journal posted to the ledger each month.

Rates, regimes and deadlines in this summary change, and many countries are actively legislating on e-invoicing. This is general information, not tax or legal advice — confirm the current position with the authority named above or with your tax adviser before you rely on it.
