When is the quarterly tax deadline for autónomos?

For Q2 2026, the main quarterly filing deadline is generally 20 July 2026. Autónomos should prepare invoices, expenses, VAT information and tax forms before this date.

Which quarterly forms do autónomos usually file?

Many autónomos file Modelo 130 for income tax prepayments and Modelo 303 for VAT. The exact forms depend on the activity, VAT situation and registration details.

Do I need to file Modelo 303 if my VAT is 0%?

Possibly yes. Charging 0% VAT does not automatically mean there is no Modelo 303 obligation. The filing obligation depends on your tax registration and activity.

Should foreign client income be included?

Yes. Foreign client income should be reviewed before quarterly filing. It may have different VAT treatment, but it can still affect Spanish tax reporting.

Can I prepare quarterly taxes without a gestoría?

Some autónomos with simple activity prepare quarterly filings themselves, but mistakes can be costly. Complex VAT, foreign clients, multiple platforms or unclear expenses may justify professional help.

Collect all sales invoices before preparing returns.

What Is the Deadline for Q2 2026?

The main quarterly filing deadline for autónomos for Q2 2026 is generally 20 July 2026.

This is the date many autónomos associate with quarterly forms such as Modelo 130 and Modelo 303.

However, your exact obligations depend on how you are registered, your activity, your VAT position and whether you had income or expenses during the quarter.

Form	Purpose	Frequency
Modelo 130	IRPF prepayment	Quarterly
Modelo 303	VAT return	Quarterly
RETA	Social Security	Monthly

1. Gather All Sales Invoices

Start with your income records. Before preparing quarterly filings, make sure you have all invoices issued during the quarter.

This may include:

Spanish client invoices
EU client invoices
Non-EU client invoices
Upwork or freelance platform income
Stripe, PayPal, Wise or bank transfer records
Any cancelled or corrected invoices

Do not rely only on bank deposits. Your tax reporting should be based on invoices and accounting records, not simply on what appeared in your bank account.

2. Review Foreign Client Invoices

Foreign clients are one of the most common sources of confusion for autónomos in Spain.

A client outside Spain may change the VAT treatment of the invoice, but it does not make the income disappear from your Spanish tax reporting.

Depending on where your client is located, you may need to consider whether Spanish VAT applies, whether the reverse charge mechanism is relevant, and how the invoice should be reported.

For a detailed explanation, see our guide on how to invoice a client outside Spain as an autónomo.

3. Check Deductible Expenses

Your revenue is not the same as your taxable profit.

Before filing, collect and review business expenses connected to your activity.

Expense	Common treatment
Professional software	Often deductible
Accounting or gestoría fees	Often deductible
Coworking space	Often deductible
Laptop or work equipment	May be deductible
Personal purchases	Usually not deductible

The expense should normally be connected to your economic activity and properly documented.

In practice, this means you should keep a clear record of invoices issued to clients and invoices or expense documents received from suppliers.

Invoice date
Invoice number
Client or supplier name
Tax ID, if applicable
Taxable base
VAT rate
VAT amount
Total amount
Whether the invoice relates to Spanish, EU or non-EU activity

AEAT explains VAT record books on its official website:

AEAT — Libros registro de IVA

AEAT also publishes electronic formats for IVA and IRPF record books that may be used for tax reviews and for importing data into certain AEAT services.

Whether you file taxes yourself, work with a gestoría or use tax software, keeping accurate invoice records throughout the quarter will save significant time when preparing quarterly returns.

5. Review Your VAT Position

VAT is one of the most common areas where autónomos make mistakes.

Some freelancers assume that if they charged 0% VAT, they do not need to file Modelo 303.

That is not always correct.

Charging 0% VAT and having no VAT filing obligation are different questions.

Read our guide on whether you need to file Modelo 303 if your VAT is 0%.

6. Prepare Modelo 130

Modelo 130 is used by many autónomos for quarterly IRPF prepayments.

Before filing, review your quarterly income, deductible expenses and any previous payments.

You should understand the difference between revenue, deductible expenses and taxable profit.

For a detailed walkthrough, see our guide on how to file Modelo 130 yourself in Spain.

7. Prepare Modelo 303

Modelo 303 is the quarterly VAT return.

Before filing, review VAT collected on sales invoices and VAT paid on deductible business expenses.

If your activity includes foreign clients, 0% VAT invoices or no invoices during the quarter, do not assume the return is automatically unnecessary.

For a detailed walkthrough, see our guide on how to file Modelo 303 yourself in Spain.

8. Check Platform and Marketplace Income

If you receive income through platforms such as Upwork, Fiverr, Stripe, PayPal or similar services, review the records carefully.

Platform payments can create confusion because the money may arrive net of fees, in a different currency, or after the invoice date.

Hacienda may also receive information from digital platforms under DAC7 reporting rules.

Read our guide on whether Hacienda can see Upwork income through DAC7.

9. Verify AEAT Access Before the Deadline

Do not wait until the final day to check whether you can access the AEAT electronic office.

Problems with a digital certificate, Cl@ve access, browser setup or bank payment can turn a simple filing into a stressful last minute issue.

Before the deadline, make sure you can log in, access the correct forms and submit payment if tax is due.

Common Last-Minute Mistakes

Many quarterly filing problems are not caused by complex tax law. They are caused by poor preparation.

Missing invoices
Forgotten foreign income
Incorrect VAT treatment
Expenses without proper documentation
Confusing bank deposits with invoices
Waiting until the final day
Digital certificate or AEAT login problems
Assuming 0% VAT means no Modelo 303

Frequently Asked Questions

Do all autónomos file Modelo 130?

Not always. Many autónomos file Modelo 130, but the obligation depends on the activity and tax registration details.

Do all autónomos file Modelo 303?

Not always, but many do. Charging 0% VAT does not automatically mean Modelo 303 can be skipped.

What if I had no income this quarter?

No income does not automatically mean no filing obligation. Your obligations depend on your registration and active tax obligations.

Can I file without a gestoría?

Some autónomos with simple activity do their own quarterly filings. However, foreign clients, VAT questions, platforms and unclear expenses can make professional help useful.

What happens if I miss the quarterly deadline?

Late filing can lead to surcharges, interest or penalties. The exact result depends on the form, timing and whether Hacienda has already issued a requirement.
