VAT Registration in Spain: Guide for Online Sellers

If you store goods in Spain, sell to Spanish consumers above the EU-wide distance selling threshold, or make taxable supplies on Spanish territory, you will need a Spanish VAT number. Registration is handled by the Agencia Estatal de Administración Tributaria (AEAT), and for non-established businesses the file is more demanding than in most other EU countries: notarised powers of attorney, corporate documents and — for many non-EU companies — a fiscal representative with joint liability.

This guide covers when VAT registration in Spain is mandatory, what the tax office expects, how the procedure runs, and which filing obligations start once your number is issued. We prepare and submit the file; the VAT number itself is issued by the AEAT.

When do I need a VAT registration in Spain?

There is no single trigger. In practice, online sellers fall into one of four situations — and any one of them is enough.

Reason 1: You store goods in Spain

Holding stock on Spanish territory makes you liable for Spanish VAT on the local supplies you make from that stock, regardless of turnover. This applies whether the warehouse is your own, a third-party logistics provider’s, or a marketplace fulfilment centre. Moving your own goods from another Member State into a Spanish warehouse is itself an intra-Community transaction that has to be reported on both sides, so the registration has to be in place before the first shipment arrives.

Reason 2: You participate in an FBA or pan-European fulfilment programme

This is the same trigger as above, but sellers frequently miss it. Programmes such as Amazon Pan-EU move inventory between countries automatically, and once your goods are allocated to a Spanish fulfilment centre the storage rule applies — enabling Spain as a storage country without a Spanish VAT number in place is one of the most common compliance failures we see.

Reason 3: You cross the EU-wide €10,000 threshold and do not use OSS

Since 1 July 2021, the individual country thresholds have been replaced by a single EU-wide threshold of €10,000, calculated as the combined total of intra-Community distance sales of goods and telecommunications, broadcasting and electronic (TBE) services to consumers across all Member States. According to the European Commission, the threshold applies to the sum of those supplies rather than to each category separately, and only to taxable persons established in a single Member State.

Once you exceed it, VAT is due in the country of the customer. From that point you have two options: register for VAT locally in Spain, or declare the Spanish VAT through the One Stop Shop. See our overview of VAT registration in Europe for how this plays out across several countries at once.

Reason 4: You make other taxable supplies in Spain

Domestic B2B sales inside Spain, intra-Community acquisitions, imports cleared in Spain and certain services connected to Spanish immovable property all create a Spanish VAT footprint. If you want to buy and sell cross-border under an EU VAT number, you also need to be listed in the Registro de Operadores Intracomunitarios (ROI) so that your number appears in VIES.

Do I need a fiscal representative in Spain?

This is the decisive question for non-EU sellers. The AEAT states that businesses established outside the European Union must appoint a representative with a tax domicile in Spain in order to comply with the obligations of Law 37/1992 (the Spanish VAT Act), unless mutual assistance instruments comparable to those in force within the Community exist with that country — currently only Norway.

• EU-established businesses: no fiscal representative required. You can register directly.
• Norway-established businesses: exempt under the mutual assistance exception.
• All other non-EU businesses (US, UK, China, Switzerland, etc.): a Spanish fiscal representative is mandatory. The AEAT confirms that UK-established businesses fall under the general rule after Brexit.

A fiscal representative is not an optional service provider: they are the point of contact for the tax office and they carry responsibility for your Spanish VAT obligations. Our guide to fiscal representation in the EU explains what the role covers.

What does a Spanish VAT number look like?

Official name	Número de Identificación Fiscal (NIF) / NIF-IVA
Country code	ES
Structure	ES + 9 characters (the first and last position may be letters)
Non-resident entities	The NIF begins with the letter N — e.g. ESN1234567X
Issuing authority	Agencia Estatal de Administración Tributaria (AEAT)

Note that having a Spanish NIF is not the same as being VIES-listed. Inclusion in the ROI is requested separately on the census declaration, and until it is granted your number will not validate for intra-Community transactions. We cover the distinction in detail in our article on the VAT number in Spain.

What documents are required for VAT registration in Spain?

• Your VAT registration certificate from your country of establishment
• A declaration stating that your company has no permanent establishment in Spain
• A notarised power of attorney appointing your local representative
• Articles of association and memorandum of the company
• A recent extract from your national commercial register
• Identification documents of the legal representative (who may need a Spanish NIF of their own, requested on form 030)
• A description of the activity to be carried out in Spain — contracts, warehouse agreements, marketplace documentation

The registration process step by step

1. Confirm the trigger and the date — first shipment into a Spanish warehouse, or the day the €10,000 threshold is crossed.
2. Appoint a representative. Mandatory for most non-EU businesses; advisable in any case, since correspondence is in Spanish.
3. Assemble and legalise the file: corporate documents, notarised power of attorney and evidence of the Spanish activity.
4. File the census declaration (modelo 036). This is the form used to request the NIF and to register in the census of entrepreneurs, professionals and withholders. For non-established businesses it is filed with the AEAT office corresponding to the tax domicile of the representative.
5. Request ROI / VIES inclusion. Registration in the Register of Intra-Community Operators is requested on the same modelo 036, by ticking box 582.
6. Answer the AEAT’s follow-up questions. The office frequently asks for further evidence of genuine economic activity in Spain before granting the number or the ROI entry — in Spanish, and on time.
7. Set up your filing calendar. Obligations start as soon as the number is active.

How long does VAT registration in Spain take?

In our own casework, a complete Spanish file is typically processed in around 4 to 6 weeks from submission. Delays are almost always caused by the same two things: incomplete legalisation of the corporate documents, and unanswered requests for additional information. ROI/VIES activation can take longer than the NIF itself, so plan your intra-Community flows accordingly.

What happens if I participate in the OSS programme?

The Union One Stop Shop lets you declare and pay the VAT due on cross-border B2C sales to all Member States through a single quarterly return filed in your country of identification, instead of registering in each destination country. The OSS return period is the calendar quarter and the return is due by the end of the month following that quarter.

What OSS does not do is remove a storage-based registration. If you hold stock in Spain, the supplies you make from that stock are domestic Spanish supplies, and they belong in a Spanish VAT return — not in the OSS return. Sellers with Spanish inventory therefore need both: a Spanish VAT number for the local flows, and OSS for the cross-border distance sales. Our guide to the One Stop Shop sets out where the line falls, and EU VAT registration explains how the two fit together.

Obligations after registration

Spanish VAT rates are 21% (standard), 10% (reduced) and 4% (super-reduced). Once registered, the following returns apply.

Return	What it is	Deadline
Modelo 303 (quarterly)	Periodic VAT return — the default regime	1–20 April, July and October; Q4 from 1 to 30 January
Modelo 303 (monthly)	Mandatory for businesses registered in the monthly refund register (REDEME) and for large companies, i.e. turnover above €6,010,121.04	1st to 30th of the following month; the January return until the last day of February
Modelo 390	Annual VAT summary	By 30 January of the following year
Modelo 349	Recapitulative statement of intra-Community transactions	First 20 calendar days of the month following the period; December / Q4 within the first 30 days of January
SII	Immediate Supply of Information — real-time invoice ledgers, mandatory for taxpayers with a monthly VAT period (REDEME and large companies)	Invoice records within 4 days; in any case before the 16th of the month following the chargeable event

Common mistakes to avoid

• Registering after the goods arrive. The obligation starts with the first taxable transaction, not with the first invoice you notice.
• Assuming OSS is enough. It never covers supplies made from Spanish stock.
• Confusing the NIF with VIES status. A valid Spanish NIF that is not in the ROI will fail a VIES check, and your B2B customers will refuse to zero-rate.
• Ignoring AEAT correspondence. Requests for information carry short deadlines and arrive in Spanish; a missed reply can mean the file is archived and you start again.
• Under-estimating the fiscal representative requirement. Non-EU sellers who plan around it lose weeks.
• Filing nil returns incorrectly. Periods with no activity still have to be declared.

FAQ – VAT registration in Spain

Which VAT rates apply in Spain?

The standard rate is 21%. Reduced rates of 10% and 4% apply to categories defined in the Spanish VAT Act, including most foodstuffs at 10% and basic staples such as bread, milk, eggs, fruit and vegetables at 4%.

How often do I have to file VAT returns in Spain?

Quarterly by default, on modelo 303. Monthly filing is mandatory for businesses registered in REDEME and for large companies with turnover above €6,010,121.04 — and monthly filers are also subject to the SII real-time ledger obligation.

Do I need a Spanish VAT number if I only sell through Amazon FBA?

If any of your inventory is stored in a Spanish fulfilment centre, yes. The marketplace may collect and remit VAT on certain sales, but it does not remove your own registration obligation arising from holding stock in Spain.

Is a fiscal representative mandatory for a US or UK company?

Yes. The AEAT requires businesses established outside the EU to appoint a representative with a tax domicile in Spain, with the sole exception of countries covered by comparable mutual assistance instruments — currently only Norway. UK-established businesses fall under the general rule following Brexit.

What happens if I register late?

Late registration does not cancel the VAT you owed in the meantime. The Spanish VAT due on past transactions has to be declared retroactively, together with late-payment interest, and surcharges or penalties may apply.

Getting your Spanish VAT registration right the first time

Spain rewards a complete file and punishes an improvised one. We prepare the documentation, handle the notarised power of attorney, file the modelo 036 with the competent AEAT office, request ROI/VIES inclusion and answer the tax office’s follow-up questions in Spanish. The number is issued by the AEAT — our job is to make sure nothing in your file gives them a reason to delay it.
