How to Invoice a Client Outside Spain as an Autónomo

One of the most common questions among freelancers in Spain is how to invoice foreign clients correctly.

The answer depends largely on where the client is located, whether the client is a business or a private individual, and what type of service is being provided.

Many autónomos work exclusively with companies outside Spain. This is especially common among software developers, consultants, designers, marketers and remote professionals working for international companies.

Understanding how VAT (IVA) works in these situations is essential to avoid mistakes when preparing Modelo 303 and Modelo 130.

Can an Autónomo Invoice Clients Outside Spain?

Yes.

Being registered as an autónomo in Spain does not limit you to Spanish customers.

You can invoice:

• Companies in the United States
• Companies in the United Kingdom
• Companies in other EU countries
• Clients located elsewhere in the world

If you are not yet registered as self-employed, see our guide on how to register as an autónomo in Spain.

What Information Should Appear on the Invoice?

A typical invoice issued to a foreign client should include the same basic information as any professional invoice.

• Your full name or business name
• Your NIF
• Your address
• Invoice number
• Invoice date
• Description of services
• Client details
• Tax treatment applied
• Total amount due

Invoices should be numbered sequentially and retained together with your accounting records.

Example: Invoicing a US Company

Suppose you provide software development services to a company located in California.

In many professional service scenarios involving a business client outside the European Union, Spanish VAT is not charged on the invoice.

The client pays the invoice amount, and the income is generally included in your normal business income reporting.

Foreign-client invoices may also become important when applying for a mortgage, renting an apartment, renewing a residence permit or responding to a bank compliance request. Learn more about what documents autónomos use instead of payslips in Spain.

Example: Invoicing an EU Company

Suppose your client is a German company that has a valid EU VAT number.

In many B2B situations, the invoice may also be issued without Spanish VAT, subject to the applicable place-of-supply rules and VAT requirements.

This is one area where freelancers should be particularly careful, because the rules may differ depending on:

• Whether the client is a business or private individual
• Whether the client has a valid VAT number
• The country where the client is established
• The type of services provided

Does 0% VAT Mean No Tax Reporting?

No.

An invoice issued without Spanish VAT does not mean the income disappears from your tax obligations.

The income may still need to be included in your accounting records and reflected in the relevant tax forms.

This is a common source of confusion for freelancers who work only with foreign clients.

What Happens in Modelo 303?

Many freelancers assume that if they do not charge Spanish VAT, they do not need to file Modelo 303.

This is often incorrect.

If you are registered for VAT obligations, Modelo 303 may still need to be filed even when no Spanish VAT has been charged to customers.

The return may still reflect business activity and deductible VAT expenses incurred during the quarter.

For a broader explanation of quarterly VAT reporting, see our guide on how to file Modelo 303 yourself in Spain.

What About Business Expenses in Spain?

This is where Modelo 303 becomes particularly important.

Imagine that during the quarter you purchased a laptop in Spain for professional use.

The VAT element and the business expense element serve different purposes.

The expense base may affect income tax calculations, while deductible input VAT is generally handled through VAT reporting.

In other words, the VAT portion should not simply be treated as the same type of expense as the taxable base.

Why VAT Should Not Be Mixed With Modelo 130

Modelo 130 and Modelo 303 serve different purposes.

If a Spanish business expense includes deductible VAT, that VAT is generally considered through Modelo 303. The base amount of the expense may be relevant for Modelo 130.

This distinction is economically important. Deductible VAT may be recovered through VAT reporting, while treating VAT only as an income tax expense generally produces a much weaker result.

For example, if €210 of VAT is deductible, VAT reporting may allow the full deductible VAT amount to be offset or recovered according to the applicable rules. Treating the same €210 only as an income tax expense would normally reduce taxable profit rather than recover the VAT directly.

For income tax prepayments, see our guide on how to file Modelo 130 yourself in Spain.

Practical Example

Consider a freelancer who:

• Earns €8,000 from a US company during the quarter
• Does not charge Spanish VAT on the client invoice
• Purchases a laptop in Spain for professional use
• Pays for Spanish internet and software services

Even though no Spanish VAT may have been charged on the client invoice, deductible VAT may still exist on some Spanish business expenses.

This is why proper accounting records remain important regardless of where clients are located.

Common Mistakes When Invoicing Foreign Clients

Charging Spanish VAT Automatically

Many new freelancers automatically add 21% VAT to every invoice. Depending on the client's location and status, this may not always be correct.

Ignoring Modelo 303

Some freelancers believe that having foreign clients means they no longer need to think about VAT returns. In reality, VAT obligations may still exist even when invoices are issued without Spanish VAT.

Mixing VAT and Income Tax

VAT reporting and income tax reporting are separate obligations. Confusing the two is one of the most common mistakes made by newly registered autónomos.

Poor Record Keeping

Invoices, expense receipts, contracts and payment records should be retained and organized.

These records are useful not only for tax purposes. Banks, landlords and immigration authorities may also request them when evaluating your income. See our guide on the autónomo equivalent of a payslip in Spain.

These documents can become important if Hacienda requests supporting information for a previously filed VAT return.

What If You Work Through Upwork or Another Platform?

If you receive income through platforms such as Upwork, the same general principles apply: the income should be recorded and reported according to your tax situation.

In addition, platform income may be reported under DAC7. You can learn more in our guide on whether Hacienda can see Upwork income through DAC7.

Final Thoughts

Working with foreign clients is completely normal for many autónomos in Spain.

The key is understanding that invoicing, VAT obligations and income tax obligations are not always the same thing.

By maintaining proper records, issuing invoices correctly and understanding the roles of Modelo 130 and Modelo 303, freelancers can avoid many common mistakes during their first years of self-employment.
