1. What is Form 349?

Form 349 is an informative tax return that must be filed by business owners or professionals who conduct transactions with other businesses or professionals located in different countries within the European Union. Its primary purpose is to collect information on intra-Community transactions subject to VAT.

2. Who is required to file Form 349?

Business owners and professionals who carry out the following transactions are required to file the Recapitulative Statement of Intra-Community Transactions:

Supplies of goods destined for another Member State that are subject to VAT.
Intra-Community acquisitions of goods subject to VAT made by persons or entities within the territory where the tax applies.
Subsequent supplies of goods following the intra-Community acquisitions of goods mentioned above.
Intra-Community supplies of services subject to tax.
Intra-Community acquisitions of services subject to tax.
Transfers of goods dispatched or transported from the territory where the tax applies to another Member State under consignment sales agreements.

3. When is Form 349 filed?

This summary return may be filed in two ways: monthly or quarterly.

  • In the case of monthly filing: this summary return shall cover transactions carried out during each calendar month and shall generally be filed during the first twenty calendar days of the month immediately following the corresponding monthly period, except for the declaration corresponding to the month of July, which may be filed during the month of August and the first twenty calendar days of September, and the declaration corresponding to the month of December, which must be filed during the first 30 calendar days of January.
  • For quarterly filings: the return must be filed within the first twenty calendar days of the month immediately following the relevant quarterly period, except for the return covering the last quarter of the year, which must be filed within the first thirty calendar days of January.

When, during the relevant quarter and in each of the four preceding calendar quarters, the total amount of supplies of goods and services to be included in the return does not exceed 50,000 euros, excluding VAT, it must be filed within the first twenty calendar days of the month immediately following the relevant quarterly period, except for the return for the last quarter of the year, which must be filed within the first thirty calendar days of January.

If, at the end of any of the months comprising each calendar quarter, the amount exceeds 50,000 euros, a return must be filed for the month or months that have elapsed since the beginning of that calendar quarter within the first twenty calendar days following, in accordance with the following criteria:

  • a) If the threshold of 50,000 euros is exceeded in the first month of the calendar quarter, a monthly return must be filed, including the transactions carried out in that month.
  • b) If the amount exceeds 50,000 euros in the second month of the calendar quarter, a monthly return must be filed, which must include the transactions corresponding to the first two months of the quarter and must include a notation indicating that it is a truncated quarter.
