What is OSS and do I need to register for it?
OSS stands for One Stop Shop. It is a single EU VAT registration that covers your sales into every member state, instead of registering separately in each one. Whether you need it comes down to one thing: whether you are the seller on the invoice.
The problem it solves
VAT on a digital product is charged where the buyer is. Sell a course to a buyer in one country and another in the next, and you owe VAT in both, at each country's own rate.
Taken literally, that means registering for VAT in every country you sell into, filing a return in each, and dealing with each tax office in its own language. For one person selling a course, that is not a business. It is a full-time job.
What OSS actually is
One registration, made in a single country, covering your sales to consumers across the EU. You file one return that reports what you owe each country, and you pay it in one place. That country's tax office splits the money and sends it on.
It does not change how much VAT you owe. It changes how many tax offices you deal with.
So do I need to register?
Only if you are the one selling to the buyer.
VAT is owed by the seller of record, the party named on the invoice and contracting with the buyer. If that is you, the obligation is yours and OSS is how you handle it sanely. If someone else is the legal seller, the obligation is theirs, and you do not register at all.
| Who does what | Selling direct | Through a merchant of record |
|---|---|---|
| Registers for OSS | You | Them |
| Charges the buyer's rate | You | Them |
| Files the return | You | Them |
| Pays the VAT across | You | Them |
| Keeps the records | You | Them |
There is no in-between. Either you are the seller and it is all yours, or you are not and none of it is.
What OSS does not cover
It covers sales to buyers in the EU. Buyers elsewhere fall under their own country's rules, and those are a separate question with separate answers.
It also does not make the paperwork disappear. You still have to charge the correct rate, prove where the buyer was at the moment of sale, file on time, and keep the records.
The records last longer than you expect
Records of transactions declared under OSS have to be kept for ten years, counted from the end of the year the sale was made. That is longer than the retention period for ordinary business records, and it applies to the evidence of where each buyer was, not only the totals.
Whoever registers is the one holding that obligation for the next decade.
How to decide, in one question
Look at the invoice the buyer receives. If your name is on it, you are the seller, and OSS is your problem to solve. If another company's name is on it, it is theirs.
Where Click2Pop fits
Click2Pop is an Estonian company and the Merchant of Record on every sale, so Click2Pop is the name on the buyer's invoice. It is registered for OSS, charges the buyer's rate, files the return from Estonia in its own name, and holds the location evidence and the records for the full ten years.
You never register for OSS on these sales, never file a return, and never deal with a foreign tax office about them. Your own tax on the money you are paid stays yours, exactly as it would with any other income.
