Modelo 347: Third-Party Operations

Modelo 347 is the annual informative declaration in which autónomos and businesses report to the Agencia Tributaria all third-party operations (clients and suppliers) where the total annual amount exceeds 3,005.06€ (IVA included). It is a purely informative filing: no tax payment is made. However, filing Modelo 347 correctly and on time is essential to avoid penalties and formal inquiries from Hacienda.

What is Modelo 347?

Modelo 347 is an annual informative declaration regulated by Real Decreto 1065/2007 (arts. 31 to 35) that requires reporting all economic operations with any single client or supplier when the annual total exceeds 3,005.06€ (IVA included).

Its purpose is to allow the AEAT to cross-check data between buyers and sellers. If you declare 8,000€ in operations with a supplier and they declare 6,000€, Hacienda will detect the discrepancy and may send a formal inquiry to both parties.

Unlike other modelos such as Modelo 303 (quarterly IVA), the 347 is not a self-assessment and does not generate any payment. It is exclusively an information obligation.

Who must file Modelo 347

Every autónomo and business that has carried out operations with any client or supplier totaling more than 3,005.06€ (IVA included) over the course of a calendar year is required to file Modelo 347.

Main exceptions — the following are not required to file:

• Those taxed under the módulos (estimación objetiva) regime for IRPF and the simplified IVA regimes, for activities subject to those regimes
• Operations already declared in Modelo 349 (intra-EU operations)
• Operations where retención was applied and already reported via Modelos 111, 115 (quarterly) or their annual summaries 190, 180, since Hacienda already has that information through those filings. In practice, this means many autónomos who declare all their operations through retenciones models do not need to file 347 at all

When is Modelo 347 due

Modelo 347 is filed once per year, during the month of February:

• Filing period: from the 1st to the last day of February. If the last day falls on a weekend or public holiday, the deadline extends to the next business day
• Year covered: all operations from the previous calendar year (January to December)

Deadline examples

Tax year	Standard period	Effective deadline
2024	February 2025	February 28, 2025 (Friday)
2025	February 2026	March 2, 2026 (February 28 falls on Saturday)
2026	February 2027	February 28, 2027 (Sunday) → March 1, 2027

What operations are included in Modelo 347

Modelo 347 reports operations with each third party that exceed the 3,005.06€ annual threshold:

• Sales and services rendered: amounts invoiced to each client
• Purchases and services received: amounts paid to each supplier
• Subsidies and grants: those received from public bodies
• Business premises rentals: if not already reported through another filing

Amounts must be broken down by calendar quarter, showing the volume of operations for each period (Q1, Q2, Q3, and Q4).

Excluded operations:

• Intra-EU operations already declared in Modelo 349
• Operations with retención already reported via Modelo 190 or Modelo 180
• Imports and exports of goods
• Intra-EU acquisitions and deliveries of goods

The 3,005.06€ threshold: worked example

The 3,005.06€ figure is calculated as the cumulative annual total (IVA included) of all operations with a single third party, not per individual invoice.

Example: Which operations must I declare?

Imagine you are a freelance designer (autónomo). During 2025, you worked with these clients:

Client	Invoices issued	Annual total (IVA incl.)	Declare in 347?
Company A	12 invoices × 300€	3,600€	Yes (exceeds 3,005.06€)
Company B	4 invoices × 600€	2,400€	No (below threshold)
Company C	2 invoices × 1,800€	3,600€	Yes (exceeds 3,005.06€)
Autónomo D	1 invoice × 3,025€	3,025€	Yes (exceeds 3,005.06€)

For Company A, in addition to the annual total (3,600€), you must provide the quarterly breakdown: for example, 900€ in Q1, 900€ in Q2, 900€ in Q3, and 900€ in Q4.

Key points for the calculation:

• Amounts are calculated with IVA included
• All invoices from the calendar year with the same third party are added together
• Both parties (buyer and seller) must declare the same amounts — Hacienda cross-checks the data

How to file Modelo 347 step by step

1. Gather your documentation

• Invoice record books (issued and received) for the full year
• NIF of each client and supplier with whom you exceeded the threshold
• Digital certificate, DNI electrónico, or Cl@ve PIN to access the Sede Electrónica

2. Calculate amounts per third party and quarter

Add up all invoices for the year with each client/supplier (IVA included). If the total exceeds 3,005.06€, you must include them with a quarterly breakdown.

3. Access the AEAT Sede Electrónica

Go to the Sede Electrónica de la Agencia Tributaria and locate Modelo 347. You can file using:

• Web form: for declarations with few records
• File import: if your invoicing software generates the file in BOE format

4. Fill in the data

For each third party exceeding the threshold, enter:

• NIF and name or business name
• Province
• Total annual amount of operations
• Quarterly breakdown (Q1, Q2, Q3, Q4)
• Operation type code (purchase, sale, rental, etc.)

5. Review and submit

Before submitting, verify that the amounts match what your clients and suppliers will declare on their end. Discrepancies are the leading cause of formal inquiries related to the 347.

Penalties for not filing Modelo 347

Since Modelo 347 is an informative declaration, penalties are governed by article 198 of the Ley General Tributaria (LGT):

Failure to file or filing with errors

• 20€ per omitted or incorrect data item
• Minimum: 300€ per declaration
• Maximum: 20,000€ per declaration

Late filing without prior formal notice from Hacienda

• Penalties are reduced to half: 10€ per item, minimum 150€, maximum 10,000€

Filing after a formal notice (requerimiento) from Hacienda

• Full penalties apply: 20€ per item, minimum 300€, maximum 20,000€

Example: If you omit 5 clients from your declaration, the base penalty would be 5 × 20€ = 100€, but the 300€ minimum applies. If you omit them and Hacienda has not yet sent a formal notice, you would pay 150€ (half of the minimum).

Note: These penalties are independent of any additional consequences if Hacienda discovers, through data cross-checking, that you have incorrectly declared IVA or other taxes.

Common mistakes when filing Modelo 347

• Mismatched amounts with the other party: if you declare 5,000€ with a supplier and they declare 4,800€, Hacienda may send a formal inquiry to both sides. Verify amounts before filing
• Excluding IVA from the calculation: the 3,005.06€ threshold refers to amounts with IVA included. Calculating without IVA may cause you to omit operations that should be declared
• Including operations already reported in other modelos: intra-EU operations (Modelo 349) and those with retención declared (Modelo 190/180) should not be duplicated in Modelo 347
• Forgetting the quarterly breakdown: in addition to the annual total, you are required to report the amounts corresponding to each quarter
• Wrong attribution period: operations are attributed to the quarter in which the invoice should be recorded, not the quarter in which payment was received or made
