VAT and OSS for Estonian E-Resident Companies

What You Need to Know

Running an Estonian company remotely often means doing business across borders. That can make VAT more complex than simply looking at where your company is registered.

E-Resident Store helps e-resident companies understand their VAT obligations, register where required and manage ongoing VAT and OSS reporting.

Does an Estonian company need to register for VAT?

Not automatically.

An Estonian company does not automatically receive a VAT number when it is incorporated. VAT registration is a separate process and must be applied for with the Estonian Tax and Customs Board.

In Estonia, mandatory VAT registration generally arises when the company’s taxable turnover with Estonia as the place of supply exceeds €40,000 from the beginning of the calendar year.

Not all international sales count toward this threshold. For example, certain B2B services supplied to foreign VAT-registered companies may be subject to the reverse-charge mechanism and may therefore not count toward the Estonian VAT registration threshold.

VAT registration can also be voluntary before the threshold is reached, but the Estonian Tax and Customs Board may require evidence that the company has genuine business activity and a sufficient connection to Estonia.

What happens after VAT registration?

Once registered for VAT in Estonia, the company receives an Estonian VAT number beginning with EE.

VAT-registered companies generally need to:

  • issue invoices according to applicable VAT rules;

  • keep VAT-compliant accounting records;

  • submit monthly VAT returns;

  • report relevant EU transactions where required;

  • pay VAT due to the Estonian Tax and Customs Board.

Estonian VAT returns are submitted monthly, including for periods where no taxable sales or input VAT occurred.

What is OSS?

The One Stop Shop (OSS) is an EU VAT reporting system designed to simplify VAT compliance for certain cross-border sales to private customers in the European Union.

Instead of registering separately for VAT in every EU country where eligible B2C sales are made, a business can use OSS to declare and pay VAT due in multiple EU Member States through a single registration.

OSS is particularly relevant for businesses selling:

  • goods online to consumers in other EU countries;

  • certain digital services to EU consumers;

  • telecommunications and broadcasting services;

  • other qualifying cross-border B2C services.

When does the €10,000 EU threshold apply?

There is an EU-wide €10,000 annual threshold for certain cross-border B2C supplies.

It applies primarily to:

  • intra-EU distance sales of goods; and

  • telecommunications, broadcasting and electronically supplied services to consumers in other EU Member States.

Subject to the applicable conditions, sales below this threshold may remain taxable in the supplier’s Member State.

Once the threshold is exceeded, VAT is generally due according to the customer’s Member State. OSS can then be used to report qualifying sales instead of registering separately in each destination country.

The €10,000 threshold does not apply to every type of cross-border service, so each business model should be reviewed individually.

Do e-residents automatically pay VAT in Estonia?

No.

E-Residency itself does not determine where VAT is payable.

VAT treatment depends on factors such as:

  • what goods or services the company sells;

  • whether the customer is a business or private individual;

  • where the customer is located;

  • where goods are stored and dispatched from;

  • whether the customer has a valid VAT number;

  • whether the transaction is B2B or B2C;

  • whether a marketplace is involved.

For example, an Estonian company providing qualifying B2B services to a VAT-registered company in another EU country may often invoice under the reverse-charge mechanism rather than adding Estonian VAT.

VAT for e-commerce businesses

VAT can become more complicated when an Estonian company sells physical goods online.

Important factors include:

  • where inventory is physically stored;

  • where goods are dispatched from;

  • the countries where customers are located;

  • whether sales are B2B or B2C;

  • whether Amazon or another marketplace is used;

  • whether local VAT registrations are required.

Storing goods in another EU Member State may create a local VAT registration obligation even where OSS is used for certain customer sales.

This is why e-commerce VAT should be reviewed before launching sales or moving inventory into a new country.

VAT for digital and SaaS businesses

For digital businesses, VAT treatment depends heavily on the type of service and customer.

For B2B services, the place of supply is often the customer’s country and reverse charge may apply.

For qualifying digital services supplied to EU consumers, VAT may instead be due in the customer’s country. OSS can be used to report eligible sales through one EU registration.

SaaS businesses should therefore collect and retain appropriate customer information to determine:

  • whether the customer is a business or consumer;

  • the customer’s location;

  • whether a VAT number is valid;

  • which VAT rate should be applied.

​Can Sunio register my company for VAT?

We can assist with Estonian VAT registration where your company has a valid basis for registration.

VAT registration is available only to customers with an active subscription to a Sunio accounting plan that supports VAT accounting. Eligible plans are:

  • Advanced

  • Advanced+

  • Flex

  • Flex Pro

The Lite plan does not support VAT accounting and is therefore not eligible for VAT registration through Sunio.


The Estonian Tax and Customs Board requests supporting information before approving an application, particularly for newly established or internationally managed companies.

This may include:

  • a description of the business model;

  • customer or supplier agreements;

  • sample invoices;

  • website information;

  • evidence of planned transactions;

  • information showing the company’s economic connection to Estonia.

Registration is therefore not automatic and is ultimately subject to approval by the Estonian Tax and Customs Board.

Can Sunio handle OSS reporting?

Yes.

We can support eligible companies with:

  • OSS registration;

  • determining the appropriate VAT treatment of transactions;

  • preparation of OSS declarations;

  • ongoing accounting for OSS sales;

  • VAT reporting in Estonia;

  • review of cross-border sales data.

Where your activity creates VAT obligations outside Estonia that cannot be handled through OSS, additional local VAT registrations or local tax support may be required.

VAT support for international businesses

To assess your VAT and OSS obligations, we may ask for information such as:

  • your business activity;

  • expected annual turnover;

  • countries where customers are located;

  • whether customers are businesses or consumers;

  • products or services being sold;

  • where goods are stored and dispatched from;

  • sales platforms and marketplaces used;

  • existing VAT registrations;

  • expected transaction volumes.

  • The earlier VAT is reviewed, the easier it is to structure invoicing and accounting correctly from the beginning.
