What are the main VAT implications if your company is registered for VAT purposes?
The following is based on the assumption that you have established an OÜ in Estonia and provide services to your clients. The provision of services to other Estonian companies and/or individuals is generally subject to the standard 24% VAT rate. However, if you provide services to clients in another EU member state or third countries, the 0% VAT rate usually applies.
If you invoice corporate customers (so-called business-to-business or B2B transactions) in other EU Member States or third countries, you must include the customer’s VAT registration number and a reference to a “reverse-charge mechanism”, meaning that you apply the 0% VAT and the customer applies and reports the VAT by self-assessment in the Member State that issued the VAT registration number.
The situation becomes a little more complicated when your customers are end consumers (so-called business-to-consumer or B2C transactions) in other EU member states or third countries. If services are supplied to end consumers outside Estonia, such supplies will be subject to Estonian VAT, unless an exception based on the nature of the service applies. In the latter case, there may be an obligation to register your company for VAT in the country where the end consumers are located and to comply with local VAT rules. Also note that depending on the type of service provided, there are rules that determine where a particular service should be subject to VAT.
If your company provides fully taxable services, you can deduct the VAT paid on the purchase of goods and services from all expenses related to your business activity of making taxable supplies (with some exceptions to the general rule). If at the end of the month you have paid more input VAT than you added to your taxable supplies, once officially approved by the tax authorities, these funds will be transferred to your prepayment account, and you can use them to cover other taxes, related liabilities or apply for a refund.
As a registered VAT payer, your company is obliged to calculate and pay VAT on its taxable supplies, goods and/or services purchased under the reverse-charge mechanism in other EU member states and third countries. In some rare cases, goods purchased from another Estonian taxpayer (e.g. scrap metal) are also subject to reverse chargeback.
The VAT taxable period is one month, and you must declare and pay VAT to the tax authorities by the 20th of the following month. You can file your VAT returns in the online e-Tax/e-Customs environment. KMD VAT returns and the KMD INF application, which lists all sales invoices with domestic counterparties that exceed €1,000 in one month, must be declared in KMD INF. Supplies of services to VAT registered customers from other EU Member States must be declared in the monthly VD declaration, due also by the 20th of the following month.
Please visit the website of the Estonian Tax and Customs Board for more information and, in particular, to understand cases where obligations may arise in a foreign country, and you may not be able to register as a VAT payer in Estonia.
Once you have decided whether you should register as a person liable to pay VAT in Estonia, you can follow the instructions of the Estonian Tax and Customs Board here.
Cases where a company must become a limited liability VAT payer.
Yes, there is another complication with VAT in the EU. Even if your company has not exceeded the €40,000 threshold, you may become restricted to paying VAT if:
- a company purchases from another VAT payer goods with a taxable value exceeding 10,000 euros (calculated from the beginning of the calendar year)
- a company receives certain services from a foreign person who is not registered as a VAT payer in Estonia. The list of services is quite large and includes such services as advertising, various types of consulting services and some financial services. We advise you to study the full list here and follow all these rules to avoid tax problems.
Thus, if a company fulfils the above framework, it is obliged to register as a VAT payer limited by guarantee. It is not a company obliged to pay VAT in the usual sense—the company must pay VAT only when purchasing goods within the Community and when receiving services from a foreign person. Please note that the company must submit a special application to the Estonian Tax and Customs Board within three days of becoming liable.
VAT Registration in Estonia: Compulsory Rules, Exemptions & How to Apply
VAT registration rules in Estonia can be complex – especially for non-residents, foreign businesses, and companies making zero-rated or intra-Community supplies. This guide breaks down exactly when registration is mandatory, when it’s optional, when you may be exempt, and how the registration process works in practice.
Compulsory VAT Registration for Non-Residents in Estonia
Foreign businesses and non-residents are required to register for VAT in Estonia if they make taxable supplies here, even without a permanent establishment in the country.
Key rules to know:
- There is no registration threshold for non-residents – unlike Estonian-resident companies (which have a €40,000 threshold), non-residents must register as soon as a taxable supply is made in Estonia
- Registration is required only when the supply falls outside the reverse-charge mechanism if the reverse-charge applies, the Estonian customer accounts for VAT instead
- Special VAT rules apply to fixed assets, distance sales, and e-commerce transactions
- If you only make zero-rated supplies in Estonia, VAT registration may not be required
If you’re unsure whether your business activities in Estonia trigger a VAT registration obligation, professional advice is strongly recommended.
Voluntary VAT Registration in Estonia
Estonian VAT law allows companies to register for VAT voluntarily before reaching the mandatory threshold or being required to do so.
To qualify for voluntary registration, your business must have actual or planned economic activity in Estonia. The main benefits of registering voluntarily include:
- Recovering input VAT – reclaiming the VAT paid on business purchases such as equipment, services, and supplies
- Smoother B2B cooperation – many VAT-registered partners and EU clients expect to see a valid VAT number on invoices
- Stronger market credibility – VAT registration signals that your business is active, compliant, and operating at scale
For startups and e-Residents with high upfront costs, voluntary registration can offer meaningful cash flow advantages from day one.
VAT Registration Exemption in Estonia: Zero-Rated Supplies
Not all businesses are required to register for VAT even when they are making taxable supplies. The key exemption applies when all of your taxable supplies are zero-rated.
However, this exemption has important limits:
- It does not apply to certain intra-Community supplies of goods and services
- In those cases, the reverse-charge mechanism may apply instead
- If any other taxable transactions (beyond zero-rated supplies) occur in Estonia, registration becomes mandatory
If your business operates primarily with zero-rated supplies but is expanding into other transaction types, it’s worth reviewing your VAT position proactively.
How to Apply for a VAT Number in Estonia: Step-by-Step
VAT registration applications in Estonia are submitted to the Estonian Tax and Customs Board (e-MTA). Here’s how the process works:
1. Submit your application electronically via the e-Customs portal (e-MTA online). This is the standard and fastest method
2. Prepare supporting documents e-MTA may request additional evidence of your business activity, such as contracts, invoices, or a business plan
3. Await the decision e-MTA will review your application and issue a decision on granting your VAT number
Processing times typically range from 5 to 10 working days for straightforward applications, though complex cases or incomplete submissions may take longer.
VAT Representatives in Estonia: When Non-EU Companies Need One
Non-EU businesses that do not have a permanent establishment in Estonia may be required to appoint a VAT fiscal representative.
This applies specifically to companies from countries that do not have VAT fraud prevention agreements with the EU. The VAT representative:
- Takes on legal responsibility for the company’s VAT obligations in Estonia
- Handles VAT filings, payments, and correspondence with e-MTA on the company’s behalf
Important exception: The VAT representative requirement does not apply to businesses registered under the OSS (One Stop Shop) scheme – except for IOSS (Import One Stop Shop), where different rules may apply.
If you’re a non-EU business selling into Estonia or the wider EU, understanding whether you need a VAT representative is a critical compliance step.
VAT representatives
Non-EU companies without an Estonian permanent establishment may have to designate a VAT representative. This is required for businesses from countries without VAT fraud prevention agreements with the EU. The representative handles the company’s VAT liabilities in Estonia. This does not apply in OSS scheme (except IOSS).
