Modelo 347: your annual report of operations with third parties

What modelo 347 is and the 3,005.06 euro threshold

Modelo 347 is an annual, purely informative return: the Agencia Tributaria calls it the annual declaration of operations with third parties. You do not self-assess any tax with it; you simply report who you had a significant volume of business with during the year.

The core rule is the threshold: you declare each client or supplier with whom, adding up every operation in the calendar year, you went over 3,005.06 euros, with IVA (Spanish VAT) and the equivalence surcharge included. It is a threshold per third party, not a general total: you can have many small invoices that together cross the figure, and then that third party is in.

• The amount counts with VAT included, not the taxable base.
• It is measured person by person: the same supplier adds up all its invoices for the year.
• Cash payments: separately from the general threshold, if you received more than 6,000 euros in cash from the same person during the year, that amount is reported apart and in annual terms.

The official form page is on the Agencia Tributaria website.

Who must file it and who does not

The obligation falls on businesses and professionals, whether autónomos or companies, that during their activity carried out operations with a third party above the threshold. It also reaches communities of property, dormant estates and, in general, any entity carrying on an economic activity.

Among those who do not file the 347:

• Anyone below the threshold with every third party: if you did not pass 3,005.06 euros with anyone, there is nothing to declare.
• Taxpayers under the SII (the Immediate Supply of Information system), who keep their VAT books in real time through the AEAT website and are therefore exempt from the 347.
• Private individuals and anyone acting outside a business or professional activity.
• Operations with no invoicing obligation and carried out outside the activity.

A point for newcomers: the 347 does not depend on your nationality or where you live, but on having an economic activity in Spain and crossing the threshold with some client or supplier.

Which operations stay out (and the line with the 349)

The 347 avoids duplicating information: if an operation is already reported to the tax office through another periodic channel, it does not come in here again. Excluded in particular:

• Operations with retención (withholding) that you already declare in the annual summaries 190 and 180: professional fees with withholding and office rent with withholding do not go in the 347, because they already travel in those forms. They are explained in the guide to modelos 111 and 115.
• Intra-EU operations: your sales and purchases with businesses in other EU countries are declared in modelo 349, not in the 347.
• Imports and exports and operations with the Canary Islands, Ceuta and Melilla.

Hence the link with the modelo 349: for the same operation it is one or the other, never both. If a sale is intra-EU, it goes in the 349 and stays out of the 347; if it is a domestic operation with a Spanish client above the threshold, it goes in the 347. This split is what most confuses people who invoice inside and outside Spain at the same time.

The quarterly breakdown and where the figures come from

The 347 is not filed as a single figure per third party: the amounts are split by calendar quarter (first to fourth), on top of the annual total. Each operation is assigned to the quarter in which the invoice has to be entered in your VAT record books, which does not always match the issue date or the payment date.

Each third party is also identified with a key according to the type of operation:

• Key A: acquisitions of goods and services, that is, your suppliers and purchases.
• Key B: supplies of goods and services, that is, your clients and sales.
• There are other keys for specific cases, such as collections on behalf of third parties or subsidies.

The figures come from your bookkeeping, the same invoices that feed your modelo 303 VAT return. kontora builds the 347 draft box by box from those invoices, places each operation in its quarter and guides you through filing on the AEAT website; submitting the form is always done by you.

The mismatch with your client or supplier

The 347 is filed by both sides of an operation: you declare your supplier and your supplier declares you. The Agencia Tributaria cross-checks the two returns, and when the amounts do not match a flag goes up. It is the most common mismatch in the form, and it is almost never a real error.

The cause is usually the timing criterion. Because each side records the invoice in its own books when it is due to, an invoice issued in December may be booked by you in the fourth quarter and by your client in the first quarter of the next year, or even in the following fiscal year. Credit notes, volume rebates or a simple typo in an amount also cause mismatches.

How it is handled:

• The two figures do not have to be identical: each party declares according to its own bookkeeping.
• Keep your invoices and record books: if the tax office asks, you justify the quarter of entry and the amount.
• Review your large third parties before filing, because a striking mismatch is the one most likely to end in a formal query.

Deadline, filing and penalties

The 347 is filed in February of the year after the one you are declaring, and always electronically. For the 2026 fiscal year the window runs from 1 to 28 February 2027; because 28 February falls on a Sunday, the last working day moves to Monday 1 March 2027. You can confirm the dates in the tax calendar and in the AEAT taxpayer calendar.

The obligation and its content sit in the General Regulation of tax management and inspection (Real Decreto 1065/2007), and the form was approved by Orden EHA/3012/2008.

Not filing it, filing it late or with incorrect data is penalised with the fines set for informative returns: fixed amounts per omitted or inaccurate data item, with a minimum per return. Filing on your own initiative, before the tax office demands it, reduces the penalty, so if you missed it, put it right as soon as possible.
