What is form 347?
Form 347 is an informative declaration that must be submitted by companies, freelancers and entities that have carried out transactions with third parties for an amount exceeding 3,005.06 euros during the calendar year. Its purpose is to provide the Tax Agency with detailed information on economic transactions carried out with customers and suppliers, allowing for better supervision and fiscal control.
Main features of form 347
- It is an informative declaration: It does not involve the payment of taxes, but its presentation is compulsory for certain taxpayers.
- Annual periodicity: It is presented once a year and includes the operations carried out in the previous fiscal year.
- Declaration limit: Only those operations with the same third party are included when the total sum exceeds 3,005.06 euros (VAT included).
- Mandatory online filing: It must be filed exclusively through the Tax Agency’s Electronic Office, thus ensuring greater efficiency and control in the process.
This form allows the Tax Agency to cross-check information between companies and professionals, verifying the accuracy of the data and avoiding possible tax discrepancies that could lead to inspections or sanctions.
Who should file it?
Form 347 must be submitted by individuals and legal entities, including the self-employed, companies and entities without legal personality, provided that they have exceeded the threshold of 3,005.06 euros in transactions with the same third party within the tax year.
Subjects required to submit form 347
- Self-employed and companies: All those who carry out economic activities and maintain transactions with suppliers or customers above the established limit.
- Non-profit organizations and homeowners’ associations: Provided that they carry out economic transactions within the business sphere that exceed the declaration threshold.
- Professionals: Lawyers, architects, consultants, doctors and any other professional who provides services subject to invoicing and who maintains commercial relations with third parties above the established threshold.
- Landlords of real estate: If the total amount of rent received during the year exceeds 3,005.06 euros.
- Public administrations: This includes town councils, official bodies and other public entities that contract or purchase goods and services that exceed the declaration threshold.
It should be noted that the obligation to submit form 347 is not limited only to those who sell products or provide services, but also to those who receive goods or contract services within the established limits.

Who is not obliged to submit it?
Not all taxpayers are required to submit form 347. There are certain exceptions and exemptions provided for in the regulations, which means that some companies, freelancers and entities are not subject to this tax obligation. It is essential to be aware of these cases in order to avoid unnecessary submissions and to ensure proper regulatory compliance.
Taxpayers exempt from submitting form 347
Below, we will mention the cases in which it is not compulsory to present this informative declaration:
- Companies and self-employed workers covered by the SII (Immediate Supply of VAT Information): Those taxpayers who present VAT through the SII are exempt from form 347, since their economic operations are reported immediately to the Tax Agency. This real-time declaration system avoids duplication of information.
- Taxpayers who have only carried out transactions exempt from VAT: Activities such as healthcare, education and financial services are exempt from VAT. In these cases, form 347 does not have to be submitted, given that no transactions subject to this tax are generated.
- Individuals under the objective estimation system (modules): Self-employed individuals who pay tax under the modules system and do not issue invoices with withholdings are not obliged to declare their operations in form 347, unless they carry out transactions outside this system.
- Operations already declared in other tax forms: Some economic operations are reported through specific forms, so they should not be included in form 347. For example:
- Form 180: Declaration of withholdings on urban leases.
- Form 180: Declaration of withholdings on urban leases.
- Form 190: Declaration of withholdings and payments on account of personal income tax for workers and professionals.
- Form 190: Declaration of withholdings and payments on account of personal income tax for workers and professionals.
- Form 349: Recapitulative statement of intra-Community transactions.
- Form 349: Recapitulative statement of intra-Community transactions.
- Forms 303 and 390: VAT returns where certain accounting movements are already reflected.
- Forms 303 and 390: VAT returns where certain accounting movements are already reflected.
It is important to check whether transactions have already been declared on another form, to avoid redundancies and possible errors in the information provided to the Tax Agency.
New developments in 2025 in relation to form 347
Every year, the Tax Agency introduces modifications and improvements to tax regulations with the aim of reinforcing transparency and control over economic operations. In 2025, some new developments have been announced that will affect the presentation of form 347, with the aim of improving auditing and facilitating tax compliance by companies and the self-employed.
Main changes in 2025 in relation to form 347
- Revision of the obligation for the self-employed to file in modules: The possibility of including in form 347 certain operations that are currently exempt is being evaluated. This modification seeks to increase control over the economic transactions of the self-employed who pay taxes under the objective estimation regime.
- Greater control over leases: The Tax Agency will strengthen surveillance of the rental of commercial premises and their correct declaration in form 347. The aim is to avoid tax fraud in leasing operations, ensuring that the income generated by these contracts is correctly declared.
- Optimization of digital auditing: Improvements will be implemented in the online filing platform for form 347, facilitating the cross-referencing of data with other tax forms. This will enable the Tax Agency to detect discrepancies more efficiently and reduce the margin of error in the filing of tax returns.
- Revision of penalties for errors in filing: In 2025, penalties for the omission of relevant data or late filing will be tightened. The aim is to encourage regulatory compliance and avoid inconsistencies in the information provided by taxpayers.
All these changes aim to increase fiscal transparency and reinforce control over economic operations, guaranteeing greater coherence in the information presented by companies and the self-employed.
