Short answer
VAT status is a small field that answers three practical questions about a company on your list: is it trading at a meaningful level, how do you invoice it, and has something recently changed. Checking it takes seconds per company and should be part of cleaning any list before it is used.
How VAT registration works in Estonia
A company must register as a VAT payer once its taxable turnover exceeds 40,000 euros, counted from the start of the calendar year. Below that, registration is voluntary. Many companies register early anyway, because it lets them deduct the VAT they pay on purchases.
A registered company gets a VAT number: the letters EE and nine digits. This is not the registry code, which has eight digits and identifies the company itself. Mixing the two up is the most common error in imported company lists.
Registration can also end. A company can be removed from the VAT register at its own request when turnover drops, or by the tax authority. So VAT status has a history: a registration date and sometimes a removal date.
What VAT status tells a salesperson
- Registered: the company has, or expects, real turnover. For most B2B offers this is the minimum sign of an active business.
- Not registered: small, new, or in an exempt field such as certain health, education or financial services. Not a reason to exclude it, but a reason to look closer.
- Recently registered: the company has just crossed the threshold or is preparing to. It is growing into needing proper accounting, invoicing and banking tools.
- Recently removed: turnover has fallen, or the company is winding down. Usually a reason to drop it from an outreach list.
What it tells finance and operations
If you invoice the company, VAT status decides how. Selling from one EU country to a VAT-registered business in another generally means the buyer accounts for the VAT, and your invoice needs their valid VAT number. If the number is wrong or no longer valid, the problem lands on you. That is why finance teams validate VAT numbers at onboarding and again from time to time.
For validation, the European Commission's VIES service confirms whether an EU VAT number is currently valid. It does not tell you the history. A company profile that shows registration and removal dates does.
Checking a whole list
- Match every row to a registry code first. Names are ambiguous; the code is not.
- Pull VAT status and dates for each code.
- Split the list. Registered, never registered, and removed are three different conversations.
- Flag recent changes. A registration or removal in the last six months is news.
- Repeat on a schedule. Status changes. A list checked once goes stale.
A worked example
An invoicing-software company wants small businesses that are about to outgrow spreadsheets. It filters for companies registered in the last three years that became VAT payers in the last six months. Each one has just crossed 40,000 euros of turnover and has just taken on monthly VAT reporting. The message, "you now file VAT returns every month; here is how to stop doing it by hand", is relevant to every row.
Common mistakes
Treating a missing VAT number as a dead company. Storing the VAT number in the registry-code field. Validating once at import and never again. And assuming the VAT rate: the standard Estonian rate has changed in recent years and has been 24% since July 2025, so do not hard-code it in templates. For amounts, use the VAT calculator.
Next step
Open any company in ContactPit to see its VAT status and dates. To use VAT status as a filter across a whole segment, start in the leadlist builder. To check it automatically inside your own system, the Data API returns VAT registration status by company.
FAQ
How do I check if an Estonian company is VAT registered?
Look the company up by name or registry code. Its VAT number and registration date are shown on its ContactPit profile, and any EU VAT number can be validated in the European Commission's VIES service.
What does an Estonian VAT number look like?
The letters EE followed by nine digits. It is a different number from the eight-digit registry code.
When must an Estonian company register for VAT?
When its taxable turnover exceeds 40,000 euros counted from the start of the calendar year. A company can also register voluntarily before reaching the threshold.
Does no VAT number mean a company is inactive?
No. It usually means the company is small, new, or sells services that are exempt from VAT. It does tell you its taxable turnover has not passed the threshold, which is useful when you are estimating size.
