Freelancers in Spain file quarterly tax returns four times a year, and the mix of returns grows when you have clients abroad. Knowing what each modelo is for, what goes in it and when it is due keeps you away from penalties and surprises at the end of the year.
The short answer: most autónomos with foreign clients file modelo 130 (income tax prepayment) and modelo 303 (VAT) every quarter, and modelo 349 (intra-EU summary) if they invoice EU business clients without VAT. The usual deadlines are the first 20 days of April, July and October and 30 January for the fourth quarter, with some differences for direct debit. Always check the current official calendar.
Forms, deadlines and rules change, and some freelancers are exempt from certain returns. This guide is general information, not tax advice. Check the calendar of the Agencia Tributaria or ask a gestor.

The three quarterly tax returns for freelancers with foreign clients
| Modelo | What it is | Who files it |
|---|---|---|
| 130 | Prepayment of IRPF for professionals in direct estimation | Most autónomos, unless most of their invoices carry withholding (the usual exemption) |
| 303 | Self-assessment of VAT | Autónomos who are VAT taxpayers, including those who invoice foreign clients |
| 349 | Summary of intra-EU operations | Those who supply services to EU business clients under the reverse charge |
Some activities use a different system for income tax prepayment, so confirm yours with a gestor.
Deadlines for quarterly tax returns
| Quarter | Period | Usual deadline |
|---|---|---|
| 1st | January–March | 1–20 April |
| 2nd | April–June | 1–20 July |
| 3rd | July–September | 1–20 October |
| 4th | October–December | 1–30 January |
If a deadline falls on a weekend or a holiday, it moves to the next business day. If you pay by direct debit, the deadline to file is a few days earlier. Check the official calendar every year.
Modelo 130: income tax prepayment
Modelo 130 is calculated on your accumulated net profit since the start of the year. As a general rule, you pay 20% of that profit, minus the prepayments from earlier quarters and any withholding already applied to your invoices. Foreign clients do not withhold IRPF, so more of the tax is paid through this return. The payment is an advance on your annual income tax; it is settled in the annual return.
- Include all income, in euros, including income received in other currencies.
- Deduct documented business expenses and, where applicable, the standard allowance for hard-to-document expenses.
- If the result is negative or zero, you may still have to file.
Modelo 303: VAT and foreign-client operations
Modelo 303 reports the VAT you charged and the VAT you paid on business expenses. Operations with foreign clients are reported in specific boxes: services to EU business clients under the reverse charge and services that are not subject to Spanish VAT are reported separately from your domestic sales. Because the boxes change from time to time, ask your gestor or follow the Agencia Tributaria instructions for the current form.
The invoice wording that supports these entries is explained in how to invoice an EU client and how to invoice a US client from Spain.
Modelo 349: summary of intra-EU services
Modelo 349 lists each EU client by VAT number, with the total amount and the operation key. It is monthly, quarterly or annual depending on the volume of your intra-EU operations. If you invoice EU business clients regularly, add it to your calendar so you never miss it.
How to prepare your quarterly tax returns in 7 steps
- Export all invoices issued and received in the quarter.
- Convert foreign-currency invoices to euros using a documented rate. See how to invoice in dollars and which rate to apply.
- Separate Spanish clients, EU business clients and non-EU clients.
- Check that every EU client has a validated VAT number.
- Total your deductible expenses and match them to invoices.
- Calculate or review modelos 130, 303 and, if needed, 349.
- File, pay and save the confirmation.
Common mistakes with quarterly tax returns
- Not reporting a foreign-client invoice because there was no VAT.
- Reporting income when it was paid instead of when it was invoiced, or vice versa, without a consistent method.
- Using an unexplained exchange rate.
- Forgetting modelo 349 for EU clients.
- Missing a deadline because the date fell on a weekend.
- Not keeping the filing receipts.
