ROI registration: the intra-community VAT number and VIES census

Last updated 22 September 2026 · Reviewed by Jaime Piñeira Pardo, lawyer registered with the ICAM bar, no. 138826 · English version of our Spanish guide.

The short answer

The ROI is the registry that assigns your VAT number with the ES prefix and lists you in the VIES census. You request it with form 036 before your first operation. The AEAT (the Spanish tax agency) has 3 months to resolve, and silence means denial. Without registration, your purchase arrives with foreign VAT and your sale cannot be exempt. Managora prepares and submits it for you.

We handle the whole procedure for you, from start to finish.

You describe your case in a chat and sign; we file it with the Spanish authorities. Fixed price from €220.00 (21% VAT included), plus the tasa (official fee) where there is one.

What is new, and the law that applies

  • Since 1 March 2020, and fully in force in 2026, the exemption of the intra-community delivery requires as a material condition that the acquirer has communicated a VAT number attributed by another Member State and that the supplier has included the operation in form 349. It comes from Directive (EU) 2018/1910 and was incorporated into Spanish law by Real Decreto-ley 3/2020. Previously they were formal requirements; now their absence overturns the exemption.
  • The annual declaration period for form 349 was abolished by Orden HAC/174/2020, of 4 February, precisely so that the information arrives close to the date of the operation. Only the monthly and quarterly frequencies now exist. However, the extended deadline for the monthly declaration for July remains in force, which can be submitted throughout the month of August and the first 20 calendar days of September.
  • Form 036 continues to be the one approved by Orden EHA/1274/2007, with subsequent updates included at the Tax Agency's electronic headquarters, the latest of them being Orden HAC/1526/2024, of 11 December.
  • In 2026, neither the 3 month period nor the negative meaning of silence has changed. What is maintained is the reinforced census control over new registrations in the ROI, with documentary verification and a visit to the declared address, aimed at cutting VAT fraud in intra-community operations.

What exactly is the ROI and what is the VAT number for?

The Registry of Intra-Community Operators (ROI) is part of the Census of Entrepreneurs, Professionals and Withholders managed by the Tax Agency. Being registered means you are assigned a VAT identification number, the NIF-IVA, which is your NIF (tax identification number) with the ES prefix in front, and this number is listed in the European VIES census, the system through which the tax administrations of the Member States check with each other who can operate without VAT within the Union.

The practical consequence is very specific. When your company is listed in VIES, the supplier from another Member State invoices you without VAT and you self-assess and deduct the tax in your own return, and your sale to a company in another Member State can be exempt. When it is not listed, the foreign supplier is obliged to charge you the VAT of their country (a VAT that you cannot deduct in your Spanish return) and your sale cannot benefit from the exemption: it must include Spanish VAT.

The VAT number is not a mere formality. It is the key that opens the destination taxation regime, and without it the operation immediately becomes more expensive and the money takes months to recover.

Who has to request registration and when?

The Tax Agency outlines 4 scenarios. First, anyone who is going to carry out intra-community deliveries or acquisitions of goods subject to the tax. Second, legal entities that do not act as entrepreneurs when their intra-community acquisitions are subject to it. Third, anyone who is the recipient of services provided by entrepreneurs not established in the territory where the tax applies and is the taxpayer for those services. And fourth, anyone who provides services that, due to location rules, are understood to be carried out in another Member State when the taxpayer is the recipient.

The third and fourth scenarios are the most overlooked. A company that only buys advertising or software from a community supplier, without moving a single box, is already obliged to register in the ROI and submit form 349, even if it does not sell anything outside Spain.

The timing is prior to the operation. The census declaration is submitted before the circumstances that justify inclusion in the registry occur, and it indicates the expected date for the first operation. Requesting registration when the invoice is already issued is late and is, furthermore, one of the reasons why the AEAT examines the file closely.

How do you apply with form 036 and how long does the AEAT take?

Registration is requested using census declaration form 036, for registration if the company is not yet in the census or for modification if it already is. You check box 582 to request registration in the Registry of Intra-Community Operators and enter the expected date for the first operation in box 584. Voluntary deregistration is requested with the same form by checking box 583 and indicating the date in box 584.

Submitting form 036 does not grant anything on its own. It opens a census verification procedure in which the Administration verifies that the declared data corresponds to reality, and to do so it can examine documentation and also the company's premises and establishments. The resolution period is 3 months.

The effect of silence is what confuses many companies: if the Tax Agency does not resolve within 3 months, the assignment of the number can be considered denied. Positive silence does not apply. Once that period has passed without an express resolution and without appearing in VIES, you are not registered, no matter how much form 036 is submitted and receipted.

If during the processing the Administration detects a discrepancy, it will notify you of a requirement or directly a proposed resolution, and the hearing process opens. Tax regulations set this period at no less than 10 days and no more than 15, and in practice the Tax Agency usually grants 10 working days. Always check the specific deadline indicated in the notification: it is, in practice, the real opportunity to save the file.

Why does the AEAT deny so much and how is the file prepared?

The ROI is the gateway to the fraud known as VAT carousel, and the Administration treats it as such. Census control over new registrations is strict and is not limited to reviewing papers: it is common for a tax agent to show up at the declared address to verify that there is a real activity there.

Denials are always repeated for the same reasons. A tax address that turns out to be just a mail reception address, with no trace of the company. Absence of material or human resources consistent with the volume of trade announced. Activity not started, without a single movement to support the forecast. Headings of the Tax on Economic Activities that do not fit with what is said to be bought or sold. And lack of any document identifying the foreign supplier or client with whom you are going to operate.

A file that holds up includes, at a minimum, proof of address (lease agreement and utilities in the company's name), proof of resources (employee registrations, service contracts, assets), identification of the community supplier or client with their VAT number verified in VIES, and proof of the commercial relationship: orders, accepted quotes, emails, pre-agreements, proformas or framework contracts. The more specific the first planned operation is, the less room there is to deny due to lack of evidence.

Managora prepares that file and submits form 036 for you, and attends to the requirement or the visit if the AEAT proposes them. You can see the updated amount in the form 036 file.

What do I do if my ROI registration is denied?

There are 2 avenues against the denial resolution, and neither can be used at the same time as the other: the optional appeal for reconsideration (recurso de reposición) before the same office that issued the act, and the economic-administrative claim. In both cases the deadline is 1 month from the day following the notification. If the denial comes by silence, the period is counted from the day the procedure can be understood as dismissed.

Appealing makes sense when the resolution ignores evidence that you did provide, when it is not motivated or when it is based on a false fact (for example, that there was no one at the address on the day of the visit, when there was). In those cases the appeal is won with the file: receipts, dated photographs, contracts and emails that dismantle the assessment of the management body.

Appealing does not make as much sense when the denial is correct. If resources were lacking, activity was lacking or documentation from the foreign client was lacking, an appeal only consumes the 1 month period and several more months of waiting. The effective thing then is to correct what was missing and submit a new application with form 036 and a better built file. The 2 avenues are not mutually exclusive: you can reapply for registration while the appeal runs its course.

Managora drafts and submits the appeal for reconsideration for you, with the ordered evidence and the request that the VAT number be assigned to you. You can see the updated amount in the AEAT appeal for reconsideration file.

How do I check a client's VAT number in VIES and why must that query be saved?

Since 1 March 2020, the exemption of the intra-community delivery ceased to be a formal issue. To apply it, it is not enough for the merchandise to leave Spain: the acquirer must have communicated a VAT number attributed by a Member State other than Spain, and you must have included the operation in form 349. These are material conditions of the exemption, not formal requirements that can be corrected later without consequences.

The verification is done in the European Commission's VIES validator or at the Tax Agency's electronic headquarters, in the query for non-Spanish intra-community operators, which requires identifying yourself with a certificate or electronic ID and indicating your NIF as the applicant, the operator's country and their VAT number. The Commission itself warns that VIES is a search engine that queries national databases in real time, and that today's validity does not guarantee tomorrow's.

That is why the query is archived. The result must be saved, with its date, together with the invoice for the operation. If months later the client loses their VAT number and a verification arrives, that receipt is what proves that you checked the number on the day you invoiced. Without it, the discussion is lost and your company ends up paying the VAT quota that it did not pass on.

The verification is done before each operation with a new client and is repeated periodically with recurring ones. Along with the receipt, it is advisable to keep proof of the transport of the merchandise, which is the other pillar of the exemption.

Can I be deregistered from the ROI without having requested it?

Yes. Registration is not for life. The Tax Agency can agree on a precautionary deregistration in the Registry of Intra-Community Operators through a motivated agreement, among other cases when it sees indications that the taxpayer participates in intra-community operations from which a tax breach or the improper obtaining of VAT refunds could derive. This precautionary deregistration becomes definitive when the census situation is rectified.

The signal that triggers the review is usually the same: stopping declaring. A registered operator who does not submit form 349 for consecutive periods, or whose VAT returns do not reflect any intra-community operation, is a natural candidate for census review. If you stop operating with the European Union, the clean thing is to request deregistration with form 036 and request registration again when needed.

Before invoicing without VAT, it is also advisable to check your own situation. The Tax Agency's headquarters allows you to consult the status of an intra-community operator and issues a tax certificate of intra-community operator that proves your registration to foreign clients and suppliers who request it.

Managora takes care of the registration, the file that supports it, the verifications in VIES and the form 349 for each period, and submits the appeal if the AEAT denies it. If your company is going to buy or sell within the European Union, leave the procedure in our hands before the first invoice, not after.

Step by step

  1. 1

    Confirm that your case requires registration(Before any operation)

    Check if you are going to make intra-community deliveries or acquisitions of goods, or receive or provide services located in another Member State where the taxpayer is the recipient. Sales to individuals in other Union countries do not go through here: they have their own regime. If your company is in the Canary Islands, Ceuta or Melilla, your shipments are exports and imports, not intra-community operations.

  2. 2

    Gather proof that the activity is real(Before submitting form 036)

    Lease agreement and utilities for the address, employee registrations or service contracts, IAE headings consistent with the activity, and documentation of the community supplier or client with whom you are going to operate: orders, quotes, emails, proformas or framework contracts.

  3. 3

    Submit form 036(Prior to the start of intra-community operations)

    Registration or modification declaration, checking box 582 to request registration in the ROI and entering the expected date for the first operation in box 584. It is submitted through the Tax Agency's electronic headquarters.

  4. 4

    Attend to the requirement or the visit from the tax agent(Hearing process of between 10 and 15 days; the specific one is set by the notification)

    The census verification may include a request for documentation, a proposed resolution or the physical examination of the address and premises. Faced with the proposed resolution, the hearing process opens, which by regulation cannot be less than 10 days or more than 15: the notification will tell you the exact deadline, which in practice is usually 10 working days. Do not answer with a generic statement: answer with documents.

  5. 5

    Check that you are listed in VIES(The AEAT has 3 months; if passed without resolution, it can be understood as denied)

    The registration is not live until your VAT number appears in the census. Check your situation at the Tax Agency's headquarters and, if a foreign client requests it, ask for the tax certificate of intra-community operator.

  6. 6

    Check and archive the VAT number of each client(Before each exempt invoice, and periodically with recurring clients)

    Before issuing an invoice without VAT, validate the client's number in VIES or at the Tax Agency's headquarters and save the result with its date next to the invoice. Also keep proof of the transport of the merchandise.

  7. 7

    Submit form 349 for each period with operations(From the 1st to the 20th of the following month, with the special deadlines for July (all of August and the first 20 days of September) and the last period of the year)

    Including the delivery in form 349 is a material condition of the exemption, not a secondary informative procedure. The frequency is monthly or quarterly depending on the € 50,000 threshold. It is not submitted in periods without operations.

  8. 8

    If denied, decide within 1 month(1 month from the notification of the denial)

    Appeal for reconsideration or economic-administrative claim if the denial ignores your evidence or is not motivated. New application with form 036 and a reinforced file if the denial is correct. The 2 avenues can coexist.

A worked example

A limited company with an address in Madrid buys merchandise for € 10,000 from a supplier in another Member State and sells merchandise for € 20,000 to a French business client. It has full right to deduction and all amounts are expressed without VAT.

  • Purchase while registered in the ROI and listed in VIES: the supplier issues an invoice for € 10,000 without VAT.
  • The company self-assesses Spanish VAT at the general rate of 21%: 10,000 x 21% = € 2,100 of accrued VAT in form 303.
  • In that same return it deducts the same € 2,100 of input VAT. Effect on the quota: 2,100 - 2,100 = € 0.
  • Purchase without being registered in the ROI: the supplier cannot apply the exemption and charges you the VAT of their country on the € 10,000. That VAT does not enter form 303: it must be claimed with form 360, with a deadline until 30 September of the following year.
  • Sale with the French client valid in VIES, proven transport and included in form 349: € 20,000 without VAT, quota € 0.
  • Sale with the client who is not listed as valid in VIES: 20,000 x 21% = € 4,200 of VAT that the company pays.

With the registration in force and the VIES query archived, the purchase results in a zero quota and the sale is exempt. Without registration and without verification, the same pair of operations leaves € 10,000 invoiced with foreign VAT pending refund for months and € 4,200 of Spanish VAT to be paid that the company rarely recovers from the client.

Frequently asked questions

How long does it take to get the VAT number?

The Tax Agency has 3 months to resolve. Many registrations are resolved sooner, but there is no guaranteed deadline and the file is not approved until your number appears in VIES. Do not plan the first intra-community delivery assuming it will arrive on time: request registration with a margin.

Can I invoice without VAT while waiting for the resolution?

No. The exemption requires that you operate as an intra-community operator and that the client has communicated a valid VAT number from another Member State. As long as you do not appear in VIES, the sale carries Spanish VAT. If you invoice without VAT and later your registration is denied, the quota will be demanded from you with interest.

What happens if I do not submit form 349 or submit it late?

Form 349 does not carry a quota, but since 2020 including the delivery in it is a material condition of the exemption. If it is missing, the Administration can deny the exemption and demand the VAT for the operation, in addition to the penalty specific to informative returns. Failing to submit it continuously is, furthermore, what usually triggers the review of your ROI registration.

Do I need the ROI to sell to individuals in other European Union countries?

That is another regime. The ROI regulates operations between companies. Distance sales to individuals in the Union are governed by a joint limit of € 10,000 per year in billing and, once exceeded, VAT is settled at the destination, normally through the one-stop shop. If you do both, you will need both registrations.

Does the ROI apply if my company is in the Canary Islands, Ceuta or Melilla?

Not for those operations. The Canary Islands, Ceuta and Melilla are outside the territory of the Community for VAT purposes, so shipments to another Member State are exports and purchases are imports, with their own customs regime. If your company pays taxes in a foral territory, the census registration is requested before your own foral tax authority with the corresponding census form.

Can I be penalised for invoicing without VAT to a client who was not in VIES?

The Administration can regularise the operation, demand the quota with late payment interest and open a disciplinary file. The defence that works is documentary: the receipt of the VIES query with the date the invoice was issued and proof of the transport of the merchandise. That is why these queries are archived operation by operation.
