If you spot a mistake in your quarterly VAT return after submitting it on Intervat, you can correct it. This article explains how to submit a VAT return correction both during and after the submission period.
⚠️ You can submit your VAT return between the 1st and the 25th of the month following each quarter.
After the deadline, corrective submissions are not possible. If the submission period has closed, you can adjust your VAT in the next quarter's return. For guidance on your specific situation, contact your Tax Coach.
1. Correction during the submission period
A. Submission via Accountable
To submit a VAT return correction through Accountable:
Log into your Accountable account and navigate to the "Taxes" section.
Locate your VAT return for the relevant quarter (Don’t forget to toggle ‘Show all [year]’ (e.g., Show all 2025) to be able to find your past submissions.)
Click on the "Mark as not done" button to unlock the VAT period.
Make the necessary corrections in the "Revenue" or "Expenses" section.
Return to the "Taxes" screen and locate your VAT return.
Click on "Submit to SPF Finance".
Input the number of declarations already filed. The app will usually suggest this automatically.
Submit the correction.
This process sends a new submission directly to Intervat, making sure your correction is filed correctly within the designated period.
B. Submission via XML file
You can also correct your VAT return using an XML file. Here is how:
Log into your Accountable account and navigate to the "Taxes" section.
Locate your VAT return for the relevant quarter (Don’t forget to toggle ‘Show all [year]’ (e.g., Show all 2025) to be able to find your past submissions.)
Click on the "Mark as not done" button to unlock the VAT period.
Make the necessary corrections in the "Revenue" or "Expenses" section.
Return to the "Taxes" screen and locate your VAT return.
Click on the 3 dots next to the "Submit to SPF Finance" option.
Click on "Email VAT return to me" to receive the XML file via email.
Download the XML file from the email.
Log in to Intervat and upload the corrected VAT return (XML file) in the 'Declaration by file' section of the dashboard.
Tick the 'Reload into the screen' option, then click "Continue".
Paste your reference number (available in your (previous) submission receipt on Intervat)
Validate the data
Click 'Next Step' and provide your comments explaining the correction.
Finally, submit your correction.
2. Correction after the submission period
If you missed the submission period, you still have options:
Submit the corrected figures in the next quarter's VAT return.
Make the necessary adjustments to the relevant grid (for example, grid 62 in the XML file) to account for any discrepancies from the previous VAT return.
Contact SPF Finances for assistance with handling corrections.
