Joining the EU VAT register

The mechanism, in one paragraph

Airbnb invoices its service from Ireland. Booking invoices from the Netherlands. Those are services supplied to a business customer in Spain, and under the general place-of-supply rule they are taxed where the customer is — here. The supplier therefore issues an invoice without VAT, and the Spanish customer accounts for the Spanish VAT itself. That is the reverse charge. For it to work, both sides need a VAT number valid for intra-EU trade, and in Spain that means being entered in the register of intra-Community operators, which produces a VAT number visible in the EU-wide VIES database.

How to apply

1. File form 036 requesting entry in the register. It can be done in the same filing as your initial registration, which saves a procedure, or later as a modification. There is no separate form and no fee.
2. Expect to be asked to justify the activity. Entry is not automatic. The tax office routinely issues a request for information before granting it, asking what the activity is, where it is carried on and what evidence exists of intra-EU operations. Answer it with documents: the tourism register entry, the property details, a platform contract or a commission statement.
3. Wait. Three to six weeks is ordinary. It can be longer in busy offices, and a request for further information restarts the clock. If your first payout is imminent, start now rather than in June.
4. Verify the number in VIES once granted. Being registered in Spain and being visible in VIES are technically the same thing but occasionally lag by a day or two. Until it is visible, the platform will keep charging you its own country's VAT.
5. Give the number to every platform you use, in the tax section of the host account. This is the step that actually changes what you are charged, and it is the one people forget after waiting six weeks for the number.
6. File the returns that now exist. The reverse charge is reported on the quarterly VAT return, and the intra-Community services received are listed on the EC sales list, form 349, for each period in which there were any.

What changes on your invoices and returns

Situation	What the platform charges	What you file
No EU VAT number	Commission plus its own country's VAT, which you cannot recover	Nothing — and that is the problem, because the obligation existed anyway
Registered, exempt lets (no hotel services: the position today)	Commission with no VAT	Quarterly VAT return declaring the reverse charge, VAT not deductible; form 349 in periods with commission
Registered, rent at 10 % (hotel services today; short stays once their VAT starts)	Commission with no VAT	Quarterly VAT return with output tax on your rents, reverse charge and input tax deducted; annual summary; form 349

The EC sales list is filed quarterly as a rule, and monthly if the volume of intra-Community operations passes the threshold set in the regulations. For a private owner with one or two flats, quarterly is what applies.

What usually goes wrong

• The request is refused for lack of evidence. Applying before any activity exists, with nothing to show, invites a refusal. Apply with the licence, the listing or the first statement in hand.
• The number is granted and never given to the platform. You continue to be charged foreign VAT you cannot recover, and you still owe the Spanish reverse charge. The worst of both.
• Only one co-owner registers. If the property is owned jointly and the activity is carried on by both, the position of each owner has to be looked at. A single registration covering a couple is a simplification somebody will eventually question.
• The reverse charge is declared but the EC sales list is not. A common and easily fixed omission, and one the system detects by cross-matching what the platform reported.
• The activity ends and the registration stays open. Returns continue to be expected. Deregister through form 036 when you stop.

If you are not resident in Spain

A non-resident owner letting a Spanish property is in exactly the same position on the commission question: the service is located where the property activity is, and the obligation is Spanish. What differs is everything else — the income itself is declared through Modelo 210 rather than through a resident return, with the rates and deadlines set out in our Modelo 210 guide. The two things run in parallel and neither substitutes for the other.

Where this sits in the bigger picture

Registration in the ROI also matters for anybody invoicing services to businesses elsewhere in the EU, which is a different conversation with the same register: no Spanish VAT on the invoice, the customer's number verified in VIES before issuing it, and the operation reported on form 349. That side is covered in invoicing abroad from Spain.

For holiday lets, the wider position — the 10 % VAT on stays of up to 30 nights, now without a start date, and the hotel-services line that decides in the meantime — is on our holiday let tax page. For clients, the registration is filed as part of the set-up, the reverse charge is computed from the platform statements you forward, and the quarterly returns follow without further involvement from you. The figures are on the pricing page.

Javier in Almuñécar and the email about a "VAT ID"

Javier lets a flat in Almuñécar with no services during the stay: his rent is exempt from VAT and he has always declared it that way. One day the platform writes asking for his "VAT ID" and warns that, without one, it will keep adding VAT to its commission. Javier replies that VAT has nothing to do with him. He is half wrong: he charges no VAT to his guests, but every month he receives a service from a European company, and that service is taxed in Spain at his expense. What is at stake is several years of VAT self-assessments and Modelo 349 returns that were never filed, and VAT that, because his letting is exempt, he cannot even recover.

What the number will look like

Your EU VAT number, the NIF-IVA, is simply your Spanish tax number with ES in front of it. The application always goes through the 036: the Modelo 037 was abolished in February 2025, so any guide telling you to use it is out of date.

One point to confirm with your adviser: if your only activity is an exempt letting, check which self-assessment form you should use to declare the reverse charge on the commission. The obligation is the same; the form is the detail to get right. The worked examples are in Modelo 349 and platform commission and the reverse charge explained.

If you have gone years without registering

This is the usual picture when someone first writes to us. The sensible course is to register and bring the missing quarters up to date before the Agencia Tributaria does, under article 27 of the General Tax Act. The cost starts small — 1 %, then a further point for every complete month of delay — and from twelve months it is 15 % with interest running from that point; paying on time and not appealing brings it down by a quarter. Once a procedure has opened for a period, that period moves from surcharge to penalty. The figures, with real numbers, are in working out the article 27 surcharge.

When the letting stops, file a further 036 to leave both the ROI and the census. An open registration keeps generating expected returns long after the last guest.
