More and more professionals and businesses in Spain work with clients in other countries. This raises one of the most common tax questions:
- Do I need to charge VAT to clients in the EU?
- Do I charge VAT to clients outside the EU?
- What is the ROI (intra-community VAT registration)?
- Can I invoice without VAT from Spain?
The answer is not always the same. VAT in Spain for international services depends on several factors: the type of client, the country, the type of service and whether you are correctly registered.
In this guide, we explain how VAT works when invoicing foreign clients from Spain and the most common mistakes to avoid.
Do you charge VAT when invoicing foreign clients from Spain?
It depends.
VAT is based on place of supply rules, which determine whether Spanish VAT applies or not.
Services to EU businesses (B2B)
If you provide services to a company established in another EU country:
- you usually do not charge Spanish VAT
- the transaction must still be declared
- you must be registered in the ROI (Register of Intra-Community Operators)
- you must file the EC Sales List (form 349)
In this case, VAT is handled in the customer’s country through the reverse charge mechanism.
Services to EU private individuals (B2C)
If your client is a private individual in the EU:
- in many cases, you must charge VAT
- or apply the OSS (One Stop Shop) regime
This is one of the most common mistakes: treating businesses and individuals the same.
Services to clients outside the EU
If you provide services to clients outside the European Union:
- in many cases, Spanish VAT does not apply
- however, the transaction still has tax implications
The correct treatment depends on the type of service provided.
What is the ROI (intra-community VAT registration in Spain)?
The ROI (Registro de Operadores Intracomunitarios) is required to invoice EU businesses without VAT.
If you are not registered:
- you cannot issue VAT-free invoices to EU companies
- you may be applying VAT incorrectly
Being registered in the ROI is essential for working correctly with EU clients.
Buying services or goods from abroad: how VAT works
International purchases also have important VAT implications.
Purchases from EU suppliers
- you usually do not pay VAT to the supplier
- but you must declare VAT in Spain using the reverse charge
This is not a VAT exemption, but a different way of reporting VAT.
Purchases from outside the EU
- imports may be subject to import VAT
- additional obligations may apply
Common VAT mistakes when working with foreign clients
These are real and frequent errors:
- invoicing EU clients without VAT without being registered in the ROI
- not submitting form 349
- charging VAT incorrectly to EU private clients
- failing to report intra-community transactions
- assuming that “no VAT” means no tax obligations
- not analysing the type of service correctly
Many of these mistakes are discovered later and can lead to penalties.
Why correct VAT treatment is important
Incorrect VAT handling can result in:
- financial penalties
- tax reassessments
- loss of deductions
- issues during tax inspections
VAT is one of the most controlled taxes in international transactions.
Can you invoice without VAT from Spain?
Yes, in certain situations.
However, invoicing without VAT does not mean there are no obligations. You must still:
- be correctly registered
- apply the correct rules
- report the transaction properly
Each case must be analysed individually.
Conclusion
Working with international clients from Spain does not automatically mean that VAT does not apply.
VAT treatment depends on:
- the type of client (business or individual)
- the country
- the type of service
- your registration status
Understanding these rules is essential to avoid mistakes and ensure compliance.
