Estonia invoice requirements 2026: what an invoice must include

Quick answer: what must an Estonia VAT invoice include?

• Use a unique, traceable invoice serial number and include the date of issue.
• Show the seller’s name, address and VAT registration number when the seller is VAT-registered.
• Show the customer’s name and address, and the customer’s VAT registration number where the VAT Act requires it.
• Describe the goods or services clearly and state the quantity or extent supplied.
• Include the supply date or advance-payment date if it can be determined and differs from the invoice date.
• Show the price excluding VAT, relevant discounts, the taxable amount by VAT rate, the applicable rate and the VAT payable in euros.

Required VAT invoice fields under § 37

The Estonian Tax and Customs Board (MTA) summarises the mandatory VAT invoice information from § 37(7) of the Value-Added Tax Act. The exact requirement can depend on the transaction, but the standard list is as follows.

Required by VAT law vs recommended in practice

Businesses often add information that is useful for payment and bookkeeping even though it is not part of the core list in § 37(7). The distinction matters: a field can be commercially useful without being a statutory VAT-invoice requirement.

VAT rates in Estonia in 2026

Estonia’s standard VAT rate is 24% from 1 July 2025. Reduced rates of 13% and 9%, a 0% rate and VAT exemptions apply only where the Value-Added Tax Act provides for them.

When must an invoice be issued in Estonia?

For a taxable person, the general rule is to issue an invoice within seven calendar days from the date the goods are dispatched or made available to the customer, or the services are provided. If the supply arises when full or partial payment is received, the invoice is generally due within seven calendar days from receipt of that payment.

There are special timing rules for some intra-Community supplies and services. For certain transactions, the invoice may be issued by the 15th day of the following calendar month. That is why cross-border transactions should not be handled by applying the domestic seven-day rule automatically.

Simplified invoices: a narrow exception

The VAT Act allows simplified invoices in specific situations, such as certain passenger transport services, parking meters, automated petrol stations and similar machines. MTA states that simplified invoices may be used when the amount invoiced does not exceed €160 excluding VAT.

A normal shop receipt is not automatically a simplified VAT invoice. MTA specifically notes that a standard retail receipt or a receipt from a staffed petrol station does not become a simplified invoice merely because it contains VAT information.

• date of issue;
• name and VAT registration number of the taxable seller;
• name or description of the goods or services;
• taxable amount and VAT payable.

Cross-border, zero-rated and reverse-charge invoices

Cross-border invoices can require additional information. For example, MTA highlights the importance of the customer’s valid VAT registration number for intra-Community supplies of goods. Special wording may also be required for reverse charge, self-billing, exemptions or other specific VAT treatments.

For intra-Community supplies, exports or services taxed outside Estonia, do not rely on a generic domestic invoice template without checking the VAT treatment. The correct wording and VAT number requirements depend on the transaction.

Is a PDF invoice valid in Estonia? What about an electronic invoice?

Yes. MTA states that an invoice may be issued on paper or, subject to acceptance by the customer, electronically. A PDF can therefore be a valid electronic invoice document when the required invoice information is present.

However, a PDF is not the same as a structured e-invoice. A structured e-invoice contains machine-readable invoice data that accounting systems can process automatically. The distinction matters when a customer is entitled to require an e-invoice rather than a PDF.

When can a customer require an e-invoice?

From 1 July 2025, an accounting entity registered in the Estonian Commercial Register as an e-invoice recipient may require the seller to submit an e-invoice for purchased goods or services. Under the Accounting Act, an e-invoice is presumed compliant if it follows the European e-invoicing standard EN 16931-1, unless the parties agree on another relevant standard.
