Almost certainly not, and the rules were rewritten specifically so that you would not have to.
But there is one thing to get straight before any of the detail, because it decides which half of the rulebook applies to you. Sell to a business in Germany and the VAT is largely their problem. Sell to a person in Germany and it is yours, and there is a machine built so that you only file in Estonia.
Those two situations get mixed together in almost every article on this, which is how founders end up paying for registrations they never needed. Everything below comes from the Commission’s own guidance. None of it is tax advice, and the detail turns on exactly what you sell.
B2B first, because it is usually not your problem
For cross-border supplies to a VAT-registered business in another member state, the customer accounts for the VAT under the reverse charge. You invoice without VAT, they declare it at their end.
That is why a consultancy in Tartu billing clients in four countries can run for years with one Estonian VAT number and no foreign registrations whatsoever.
There is one obligation that comes with it and it is the bit people forget. Those supplies have to be reported in a recapitulative statement, the EC sales list, governed by Articles 262 to 271 of the VAT Directive. It lists each business customer and the total value supplied to them. The default is monthly, with member states permitted to allow quarterly filing.
All of which applies inside the EU only. The moment you sell outside it the logic changes completely, and I went through the UK version separately, where the threshold everyone quotes does not apply to you at all.
Worth knowing that the EC sales list is on its way out. Directive (EU) 2025/516, the ViDA directive, provides for removing the recapitulative statement obligation and folding those transactions into digital reporting requirements instead, with more detailed and more timely data. I could not confirm the application date for that part from the sources I could reach, so treat it as a change coming rather than one to plan a quarter around.
B2C: the threshold, exactly
Here is where the EUR 10,000 figure comes in, and it is worth having precisely rather than roughly, because the precise version is narrower than the folklore.
Per the Commission’s Guide to the VAT One Stop Shop, the threshold applies when three conditions are all met. You are established in only one member state. You supply B2C telecommunications, broadcasting and electronic services into another member state, or goods dispatched from the member state where you are established. And the total of those supplies does not exceed EUR 10,000 excluding VAT in the current and the preceding calendar year.
That last clause catches people. One good year above the line and the following year starts above it too.
Under the threshold, you charge Estonian VAT and the supplies are treated as domestic. The guide is explicit that the One Stop Shop is not relevant in that situation, because those supplies cannot be declared in it at all. Over the threshold, VAT belongs to the customer’s member state, and the Union scheme lets you charge each country’s rate and declare the lot in one return filed in Estonia.
One thing to decide deliberately rather than by accident: you may opt into destination taxation voluntarily while still under the threshold, and that decision binds you for two calendar years. Registering for the Union scheme applies the destination rules automatically.
Two traps that break the threshold entirely
Both of these are in the guidance and neither is in the summaries.
Only goods shipped from Estonia count. The guide states that only intra-Community distance sales supplied from the member state where you are established go into the EUR 10,000 calculation. Sales made from a stock of goods held in another member state are excluded from the calculation, and the place of supply for those is the destination country regardless of your volume.
Read that twice if you use a fulfilment network. The moment your stock sits in a warehouse in Poland or Germany, those sales are taxable there whether you have sold EUR 500 or EUR 500,000, and that is the situation where a local registration genuinely is required.
There is relief coming. The same guide notes that a new transfer of own goods scheme enters into force on 1 July 2028, along with a broader extension of the schemes, with completely new guidelines to follow. Until then, holding stock abroad means registering there.
The threshold does not cover ordinary services. It applies to TBE services and to intra-Community distance sales of goods, and the guide says plainly that it does not apply to services which are not TBE services, nor to distance sales of imported goods.
So if you sell a service to consumers in other member states and it is not telecommunications, broadcasting or electronic, the EUR 10,000 line is simply not your rule. Which rule applies depends on the service, and that is the point at which you want an accountant rather than an article.
What the One Stop Shop actually costs you in admin
Not much, and the four things worth knowing in advance.
The Union scheme return is quarterly, due by the end of the month following the end of the period. So the first quarter is due on 30 April.
If you make no OSS supplies anywhere in the EU in a period and have no corrections, you still file a nil return.
The OSS return does not replace your Estonian domestic return. It sits alongside it.
And the one that surprises people: you cannot offset input VAT in the OSS return. Expenses incurred in a member state of consumption have to be reclaimed through the electronic VAT refund mechanism under Directive 2008/9/EC, or through a domestic return if you are registered but not established there. So OSS simplifies declaring the VAT you owe and does nothing about the VAT you have paid.
Records, incidentally, have to be kept for ten years from the end of the year in which the transaction took place.
What changes on 1 January 2027
Worth knowing because it means the guidance you find on a random accountancy blog is probably describing 2021.
The current Commission guide is dated July 2026 and has been revised specifically for the ViDA changes entering into force on 14 April 2025 and on 1 January 2027. Among the 2027 changes, the Union scheme’s scope for intra-EU goods widens between 1 January 2027 and 1 July 2028, website data stops being a mandatory registration field, and a VAT group indicator becomes required where applicable.
The guide also says, in its own words, that it is not legally binding and is informal practical guidance reflecting the views of DG TAXUD. I would read that as an instruction to use it for orientation and your accountant for decisions, which is roughly how I would treat this post too.
Before lunch
Thirty minutes, and the first item is the one that costs money if you get it wrong.
Split last year’s non-Estonian sales into two columns: sales to VAT-registered businesses, and sales to consumers. Only the second column is in scope for any of this.
Add up the consumer column, excluding VAT, for this year and last year separately, counting only goods dispatched from Estonia and TBE services. Compare each against EUR 10,000.
Then answer one question honestly: does any of your stock sit outside Estonia? If it does, that is a separate and more urgent conversation, and it is worth having this week rather than at year end.
If you’d like to think through which column your revenue actually sits in before you take it to an accountant, drop me a line on email, WhatsApp, phone or LinkedIn and we can have a quick chat, and my notes on how I work cover the rest. I’m taking on a small number of contracts at the moment, so I’ll tell you straight whether it’s something I could help with.
