Quarterly VAT and IRPF checklist

The awkward part of a quarterly filing is rarely the final click. It is the half hour before it, when you realize one supplier invoice is missing, a client payment had withholding, or the deadline for direct debit is not the same as the deadline for filing.

For freelancers and small businesses in Spain, the usual quarterly rhythm brings two forms into the same calendar window: Modelo 303 for VAT self-assessment and Modelo 130 for IRPF prepayments when the activity is taxed under direct estimation. They are separate forms, but they should be prepared together. Not because the figures must match. They often will not. Because both forms depend on the same underlying discipline: knowing the period, checking the invoices, and choosing the payment method before the filing window gets tight.

Start with the calendar, not the form

For quarterly filers, AEAT lists Modelo 303 and Modelo 130 in the same main filing windows for 2026:

First quarter 2026: up to 20 April 2026.
Second quarter 2026: up to 20 July 2026.
Third quarter 2026: up to 20 October 2026.
Fourth-quarter filings are handled in January, with AEAT’s general quarterly presentation window running from 1 to 30 January for Models 130 and 303/309.

For an article dated 11 June 2026, the immediate practical date is the second quarter: the 2026 AEAT calendar places Q2 Modelo 303 and Q2 Modelo 130 up to 20 July 2026.

One detail matters if you pay by direct debit. AEAT’s 2026 calendar gives a shorter direct debit window for quarterly Modelo 130 and quarterly Modelo 303/309: generally from the 1st to the 15th of April, July and October, and from the 1st to the 25th of January. For Q2 2026, that means the direct debit window runs from 1 to 15 July 2026, while the general filing window runs to 20 July 2026.

If the last day falls on a non-business day, AEAT states that VAT filing deadlines move to the next business day, and its calendar also explains the general rule for local or regional holidays. Do not treat that as permission to wait. Treat it as a safety rule for edge cases.

Check whether Modelo 130 applies to you

Modelo 130 is for IRPF prepayments by entrepreneurs and professionals in direct estimation. AEAT describes it as the form that allows businesses and professionals to file and consult returns and make IRPF instalment payments.

There is an important exception for professional activities. AEAT’s Modelo 130 instructions state that individuals carrying out professional activities do not have to file the instalment payment return, or make a payment under that concept, if at least 70% of the income from those activities in the immediately previous calendar year was subject to withholding or payment on account. If the activity has just started, the percentage is checked using the income subject to withholding or payment on account during the quarterly period.

That rule is easy to misread. It does not say every freelancer is exempt. It says the exemption depends on the nature of the activity and the withholding percentage. Before filing, check your actual invoices for the period and the previous-year rule that applies to your case.

Prepare Modelo 303 as a VAT self-assessment

AEAT identifies Modelo 303 as the VAT self-assessment form. For quarterly VAT returns, AEAT’s VAT deadline page gives the general period as the 1st to the 20th of the month following the settlement period: April, July and October. The fourth quarter runs from the 1st to the 30th of January.

Before filing Modelo 303, the practical review is simple:

Confirm the quarter you are filing.
Check that all issued invoices for the period are included.
Check that supplier invoices and expenses used for the VAT return belong to the period and are properly recorded.
Decide whether you will pay by direct debit before the shorter direct debit window closes.
If you are using AEAT’s electronic service, make sure your identification method is ready before the final day.

AEAT’s Modelo 303 procedure page links to the 2026 electronic filing service, the Pre303 help service and the 303 simulator. Those tools do not replace a clean review of your records, but they are the official place to prepare or test the filing route.

Prepare Modelo 130 from accumulated figures

Modelo 130 is not built only from the quarter in isolation. AEAT’s instructions say that, for activities in direct estimation other than agricultural, livestock, forestry and fishing activities, the requested figures are generally accumulated from the first day of the year to the last day of the quarter being filed.

That means the second quarter is not just “April to June” in the way many people instinctively think about it. For the relevant Modelo 130 boxes, you are working with year-to-date figures up to the end of Q2.

AEAT’s instructions also set out the main mechanics:

Income and deductible expenses are reported for the accumulated period.
The net result is calculated by subtracting deductible expenses from computable income.
For the general direct-estimation activity section, the positive net result is multiplied by 20%.
Withholdings and payments on account supported during the period are included in the calculation.
Previous positive Modelo 130 amounts from the same year and certain negative results from prior quarters may affect the final amount, according to the form instructions.

There are special sections and percentages for agricultural, livestock, forestry and fishing activities, and specific rules for Ceuta and Melilla. If your activity falls into one of those categories, do not reuse the general professional-services workflow without checking the corresponding section of the AEAT instructions.

Reconcile the two forms before you submit

Modelo 303 and Modelo 130 answer different tax questions. VAT and IRPF are not the same calculation, and the final amounts do not need to mirror each other. Still, preparing them side by side catches boring mistakes before they become official mistakes.

A sensible pre-filing pass looks like this:

The quarter is the same on both forms.
The filing year is correct.
Invoices with IRPF withholding have been treated consistently in your records.
Expenses used for Modelo 130 are supported and assigned to the right period.
VAT records used for Modelo 303 are complete enough for the quarter.
The payment method is chosen before the direct debit deadline, if you plan to use direct debit.
Your certificate, DNI electronico or Cl@ve access is available before the final filing day.

AEAT states that electronic presentation may be made using certificate, electronic DNI, Cl@ve or reference number, with limits depending on the taxpayer and form. For companies such as S.A. and S.L., AEAT’s calendar reminder states that internet filing with electronic certificate is mandatory for informative returns, self-assessments and, generally, census returns.

A short filing-day checklist

Before submitting, do one final pass in this order:

Confirm the model: 303 for VAT self-assessment, 130 for IRPF instalment payment under direct estimation when applicable.
Confirm the period: first, second, third or fourth quarter.
Confirm the deadline: for Q2 2026, AEAT lists both quarterly Modelo 303 and Modelo 130 up to 20 July 2026.
Confirm direct debit timing: for Q2 2026, AEAT lists direct debit for quarterly Modelo 303/309 and Modelo 130/131 from 1 to 15 July 2026.
Review Modelo 130 with year-to-date figures where the instructions require accumulated amounts.
Check whether the 70% withholding rule affects your obligation to file Modelo 130.
Save the filing confirmation and payment evidence after submission.

The calm version of quarterly filing starts a few days before the form opens. By the time you enter AEAT’s site, the numbers should already have been reviewed, the payment route chosen, and the deadline checked against the official calendar.
