VAT fiscal representative Spain: +80 foreign companies, 100% returns on time, recover unpaid VAT

A VAT fiscal representative in Spain (representante fiscal a efectos del IVA) is a person or entity resident in Spain appointed by a non-established foreign company to manage its Spanish VAT obligations before the AEAT (Spanish Tax Agency). Under Article 164 of the Spanish VAT Law (Ley 37/1992) and its implementing regulations, companies established outside the EU that carry out VAT-liable transactions in Spain without a permanent establishment are legally required to appoint a fiscal representative; EU-established companies may register directly but frequently appoint a representative for practical compliance management. The fiscal representative assumes joint liability to the AEAT for the represented company's Spanish VAT obligations.

We act as VAT fiscal representative for more than 80 foreign companies with operations in Spain. Our knowledge of Spanish VAT law and AEAT procedures ensures timely compliance and correct management of indirect tax obligations.

When Spanish VAT applies to non-established businesses — and when it doesn’t

The Spanish VAT system applies specific rules to companies that carry out transactions in Spanish territory without having their registered office or a permanent establishment there. The registration obligation is not automatic: it depends on the type of transactions performed, whether the customer is a business or a final consumer, and the country of establishment of the foreign company. Foreign companies that begin operating in Spain — selling to Spanish clients, attending trade fairs, purchasing materials from local suppliers, or providing digital services to final consumers — frequently do not know that these operations can generate Spanish VAT obligations even without a permanent establishment in Spain.

Undeclared VAT accumulates month after month with late-payment interest at 3.75% per year and surcharges that can reach 20% of the unpaid amount. And when the AEAT initiates a review — typically because the Spanish customer has deducted VAT from invoices issued by the foreign company without the company being registered — the regularisation includes retroactivity of up to four years with all accumulated interest and surcharges. The complexity increases with the various special regimes: the reverse charge mechanism, the OSS/IOSS regime for digital sales, and the non-established business refund procedure. A company that ignores these rules may be accumulating undeclared tax obligations without being aware of it.

Our VAT fiscal representation model

Acting as a VAT fiscal representative in Spain implies assuming joint liability to the AEAT for the tax obligations of the represented company. For this reason, our service always begins with a rigorous analysis of all transactions the company carries out or plans to carry out in Spain, defining the precise perimeter of VAT obligations: we review the nature of the operations — supply of goods, intra-community services, B2C e-commerce — and determine whether they generate Spanish VAT, whether the reverse charge rule applies (transferring the settlement obligation to the Spanish customer), or whether the company can operate under the applicable special VAT regime.

Once obligations are determined, we manage census registration via AEAT Form 036, enrolment in the Register of Intra-Community Operators (ROI) where the company carries out intra-community transactions, and the formal designation of the fiscal representative. From there we manage the periodic declaration cycle and, where applicable, claims for refund of VAT incurred.

This service integrates naturally with our international tax advisory, where we analyse the interaction between Spanish VAT and the direct taxes of the company in its home country, including IRNR where the activity generates income subject to Spanish non-resident income tax. For companies that also have other Spanish taxes to manage, our non-resident taxation service provides complete coverage. If your company is considering establishing a permanent legal presence in Spain, our entity management team can accompany that next step without losing continuity of the tax compliance already established.

What our VAT representation service includes

The service covers the Spanish VAT obligations analysis for the client’s specific business model, census registration with the AEAT (Form 036) and ROI enrolment, formal fiscal representative designation before the AEAT, periodic Form 303 submission (monthly or quarterly), Form 349 for intra-community transactions, annual summary Form 390, claims for refund of VAT incurred under Directive 2008/9/EC or reciprocity procedure, OSS/IOSS regime management for digital sales to EU final consumers, and direct AEAT liaison for all information requests, inspections, and appeals related to Spanish VAT.

Real results for foreign companies operating in Spain

100% of returns filed on time across our active client base, with zero surcharges for late filing. Retrospective review of Spanish VAT incurred by new clients has identified on average recoverable amounts of EUR 1,500 to EUR 15,000 in the first year of review, depending on the volume of expenses in Spain. Census registration and fiscal representative designation are completed in under two weeks from mandate, enabling the company to begin operating correctly in Spain without risk of accumulating undeclared obligations. And the joint liability we assume as fiscal representatives is the strongest guarantee that we manage each obligation with maximum diligence.

Frequently asked questions about Spanish VAT for foreign companies

Many foreign companies are unaware that they can recover Spanish VAT they have incurred on purchases in Spain: expenses at trade fairs and events, material purchases, local professional services, or fuel. The non-established business refund procedure — Directive 2008/9/EC for EU companies, or the reciprocity procedure for third-country companies — allows recovery of amounts that are in some cases significant. Our team reviews the history of Spanish expenses for each new client to identify whether there is recoverable VAT from prior years and manages the claim accordingly. For companies with international trade operations, this service complements our customs and trade advisory, where correct management of import VAT is another relevant vector of tax optimisation.
