Services provided by businesspersons or professionals are taxed, as a general rule:
When the customer is a trader or professional, where they have the base of their economic activity or they have a permanent establishment or their habitual residence where they receive the service
When the customer is a private individual, where the provider has their place of business, a fixed establishment or their habitual residence from which they provide the service.
If a trader established in the territory of application of the Spanish VAT (TAI) supplies a service to a trader established in another country, the transaction is not subject to Spanish VAT, giving the right to deduct input VAT on purchases of goods and services that are affected by this activity in the same way as if it had been carried out in the TAI.If the customer is a businessperson from another Member State, this is an Intra-EU supply of services to be reported on Form 349.Finally, if the customer is a private individual, the transaction is subject to Spanish VAT, which will be paid by the service provider, except for certain services when the customer is established outside the Community (except for the Canary Islands, Ceuta or Melilla), for example, advertising, advisory, auditing, engineering, legal, consultancy or translation services.
If a trader established in the Spanish VAT territory receives a service from a trader established in another country, the transaction is subject to Spanish VAT.VAT is settled by the customer, through the mechanism known as reverse charge, declaring, as a general rule on Form 303, the Spanish VAT accrued on the transaction which, in turn, may be deducted when the established requirements are met (Articles 92 et seq.Law 37/1992).If the supplier is a businessperson from another Member State, this is an Intra-EU acquisition of services, which is also to be reported on Form 349.
However, there are special rules for certain services set out in Article 70 of Law 37/1992, e.g. services related to immovable property are located where the property is situated, access to cultural events in the territory where they take place or catering services where they are physically provided.
In order to find out whether the service you are going to perform is subject to Spanish VAT, you can access the "Locator", located in the "VAT Tools".
