How long does EU VAT registration take?
EU VAT registration can take a very different amount of time in each country. You need to factor this in when you plan to trade in new territories, so you remain compliant. The Taxually team of tax experts has compiled the guide below. It shows how long EU VAT registration takes in key markets.

Why do VAT registration times differ between EU countries?
Each EU country runs its own VAT registration process. Tax authorities set their own document requirements, checks and language rules. An application that is incomplete, or that triggers follow-up questions, takes longer to approve.
How can you avoid VAT registration delays?
- Confirm you need to register. Check which activity triggers registration in each country. Our guide to the common triggers for VAT registration in the EU covers the main cases.
- Prepare documents early. Gather your company documents and home-country tax details before you apply. Check whether the tax authority needs translations.
- Apply before you start selling. Use the registration times above to plan your launch date in each market.
- Check if you need a fiscal representative. Non-EU businesses often need one. Appointing one adds a step, so start early. See what fiscal representation is and whether you need it.
- Answer queries quickly. Tax authority questions pause your application until you reply.
Do you need a VAT number in every EU country you sell to?
Not always. A €10,000 EU-wide threshold applies to distance sales to consumers in other EU countries. Below it, certain sales can stay taxable in your home EU country.
Above the threshold, the One Stop Shop (OSS) lets you register in one EU country to declare and pay VAT on your cross-border distance sales. This is explained on the EU's Your Europe cross-border VAT page. Other activities, such as storing goods in another EU country, can still require a local VAT registration.
When does an OSS registration take effect?
An OSS registration normally takes effect on the first day of the calendar quarter after you notify your EU country of identification. You can start earlier if you notify that country quickly after your first sale.
The European Commission sets out the rules on its OSS registration page:
- Standard start: if you notify on 15 February, the scheme applies from 1 April.
- Early start: if your first eligible sale comes before that date, OSS can apply from the date of that sale. You must notify by the 10th day of the month after the sale.
- Late notification: if you miss that deadline, you must register and account for VAT directly in each EU country where your customers are.
- Changes to your details: report them by the 10th day of the month after the change.
For example, a seller whose first cross-border sale to a consumer is on 20 May must notify by 10 June to use OSS from 20 May.
When are OSS returns due?
OSS returns under the Union and non-Union schemes are filed every quarter. The return and the payment are due by the end of the month after the quarter:
- Q1: 30 April
- Q2: 31 July
- Q3: 31 October
- Q4: 31 January of the following year
The Import One Stop Shop (IOSS) works differently. Its tax period is the calendar month.
How do you check that an EU VAT number is valid?
Use the European Commission's VIES tool. It searches the national VAT database of the country that issued the number and shows whether it is valid for cross-border trade.
- Search the number. Enter the country and VAT number in VIES.
- Read the result. An invalid result means the number is not in the national database.
- Find out why. The number may not exist, may not be activated for intra-EU trade, or the registration may not be finished.
- Ask the national tax authority if needed. It will not give out a name or address. It can confirm whether a name and address match a number.
- Keep a record of each check. You may need it in a tax audit.
This matters for your own new number too. National database updates may not show in VIES straight away, so check your number before you give it to EU business customers.
