Intervat XML file

Generate the XML file of the periodic return for Intervat, understand its content and prepare the declarant's data.

Updated on 10/05/2026 Edit this page

Intervat is the application of FPS Finance for the electronic filing of VAT returns. NovaFisko produces the XML file of the return in the expected format: you download it, then you file it yourself on Intervat with your usual access.

Generating the file

  1. Open the VAT tab.
  2. Open a return in the Draft, Validated or Filed state.
  3. Click Intervat XML.
  4. The file is downloaded under the name intervat_CODE_YEAR_PERIOD.xml, where CODE is the code of the company file.
Warning

Generate the file to be filed from a validated return. The XML of a draft is technically available for a check, but its grids may still change. Each download is recorded in the activity of the company file.

What the file contains

The file is a VATConsignment consignment containing one return.

Item Value
Declarant reference NOVAFISKO- followed by the internal identifier of the return.
VAT number That of the company file, without the BE prefix.
Name Name of the company file.
Address Street, postal code and city taken from the address of the company file; country BE.
E-mail and phone Those of the firm.
Period The month or the quarter, and the year.
Amounts One line per non-zero grid, with its number and its amount to two decimal places.
Nil client listing "NO": the annual listing is the subject of a separate file.

Grids at zero are not written to the file: this is the behaviour Intervat expects.

Preparing the data of the company file

A correct file requires correct identity data. Before the first filing, check in Settings:

  1. Company details: the name, the VAT number and the Address. The address must fit on two lines, the street and number on the first, the postal code and city on the second: this is how the file tells the street, the postal code and the city apart.
  2. Admin. / VAT, VAT tab: the Periodicity and, if you use them, the administration cell number, the structured communication for payment, the directorate number and the collection office number.
  3. Admin. / VAT, VAT filer tab: the capacity of the filer, "The company itself" or "Accountant / accounting firm", with its name, enterprise number, phone and e-mail.
  4. Admin. / VAT, Declarant tab: to be filled in if the person who signs the return differs from the company file.

Also check the e-mail and the phone in Firm settings: they are the ones that appear in the file.

Note

The administrative references (cell, collection office, signatories) are recorded in the company file for your documents and your exchanges with the tax administration. The XML file, for its part, contains the identity of the declarant, the period and the grids.

Filing on Intervat

  1. Log in to Intervat with your certificate or your usual means of identification, as a proxy holder if you file for a client.
  2. Choose to file an XML file and select the downloaded file.
  3. Check the summary shown by Intervat: period, VAT number and grids.
  4. Sign and send.
  5. Keep the acknowledgement of receipt.
  6. In NovaFisko, click Mark as filed and enter the reference of the acknowledgement.

NovaFisko transmits nothing to the tax administration: filing remains an action you carry out on Intervat. Before your very first real filing with a NovaFisko file, check the summary shown by Intervat carefully and compare it with the return in the VAT tab.

If Intervat rejects the file

Likely cause Correction
VAT number missing or incorrect Correct the VAT number of the company file in Settings, then generate the file again.
Period already filed Check the state of the period on Intervat; a corrective return is filed according to the Intervat procedure.
Incomplete address Put the address of the company file on two lines, then generate the file again.
Inconsistency between grids Go back to the return and check the warnings and the VAT codes of the entries concerned.

The file can be generated again at any time: the grids of a validated return do not change, only the identity data is read again.
