What is Modelo 347 and Who Must File It?
Modelo 347 is an annual informative tax return that self-employed freelancers and businesses in Spain must submit to report transactions with any single client or supplier exceeding €3,005.06 (VAT included) within a calendar year.
While filing this form does not require any tax payment, it is one of the Spanish Tax Agency’s (AEAT) primary data-crosschecking mechanisms to detect discrepancies between declared sales and purchases. It applies to all individuals and legal entities operating in Spain, with specific exemptions such as:
* Businesses with operations that do not reach €3,005.06 with any single entity.
* Taxpayers already using the SII (Immediate Supply of Information) system.
* Transactions already declared in withholding returns (such as Modelo 190 for professional fees or Modelo 180 for property rentals).
How the €3,005.06 Threshold is Calculated
The calculation considers cumulative transactions linked to the same Tax ID (NIF/CIF) during the tax year. Key rules include:
1. VAT included: The threshold is evaluated on the final total invoice amount, including VAT and surcharges.
2. Quarterly breakdown: Operations must be reported broken down by fiscal quarter according to invoice dates.
3. Cash accounting regime: If enrolled in the Special Cash Basis Regime (*criterio de caja*), entries are declared in the quarter when payment or collection occurred.
Supplier and Client Reconciliation: Avoiding Audits
The most frequent discrepancies in Modelo 347 arise from timing differences: invoices issued late in one quarter that the receiving party registers in the subsequent one.
While the AEAT generally tolerates minor quarterly timing shifts if the overall annual figure matches, it is best practice to circulate balances and confirm totals with key business partners ahead of the February filing deadline.
Moving Toward Automated Reconciliation: The Role of VeriFactu
The ongoing digital tax rollout will fundamentally simplify this verification process. Under current regulations, compliance deadlines are set for January 1, 2027, for incorporated companies and July 1, 2027, for sole traders and freelancers.
In preparation for the mandatory calendar outlined in our guide to VeriFactu 2027, many businesses are moving away from manual spreadsheets. Modern workflows make it straightforward to importar Excel a VeriFactu, execute migrations when you importar Factusol a VeriFactu, or transition data when you importar Sage 50 and importar Holded into cloud platforms. For technical architectures, implementing an API VeriFactu, utilizing a pasarela VeriFactu para software, or configuring an integración ERP VeriFactu guarantees accurate, certified records.
