When filing your quarterly VAT return on Intervat, you may realize that a mistake was made in your submission. If this happens, don't worry, you can correct it. Below is a guide on how to correct your VAT return, 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. For assistance, please reach out to your Tax Coaches.

1. Correction during the submission period

A. Submission via Accountable

To submit a VAT return correction through Accountable:

  1. Log into your Accountable account and navigate to the "Taxes" section.

  2. 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.)

  3. Click on the "Mark as not done" button to unlock the VAT period.

  4. Make the necessary corrections in the "Revenue" or "Expenses" section.

  5. Return to the "Taxes" screen and locate your VAT return.

  6. Click on "Submit to SPF Finance".

  7. Input the number of declarations already filed. The app will usually suggest this automatically.

  8. Submit the correction.

This process will send a new submission directly on Intervat, making sure your correction is filed correctly within the designated period.

B. Submission via XML File

Alternatively, you can correct your VAT return using an XML file. Here's how:

  1. Log into your Accountable account and navigate to the "Taxes" section.

  2. 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.)

  3. Click on the "Mark as not done" button to unlock the VAT period.

  4. Make the necessary corrections in the "Revenue" or "Expenses" section.

  5. Return to the "Taxes" screen and locate your VAT return.

  6. Click on the 3 dots next to the "Submit to SPF Finance" option.

  7. Click on "Email VAT return to me" to receive the XML file via email.

  8. Download the XML file from the email.

  9. Log in to Intervat and upload the corrected VAT return (XML file) in the 'Declaration by file' section of the dashboard.

  10. Tick the 'Reload into the screen' option, then click "Continue".

  11. Paste your reference number (available in your (previous) submission receipt on Intervat)

  12. Validate the data

  13. Click 'Next Step' and provide your comments explaining the correction.

  14. Finally, submit your correction.

2. Correction after the submission period

If you missed the submission period, you still have options:

  1. Submit the corrected figures in the next quarter's VAT return.

  2. Make necessary adjustments to the grid (e.g., grid 62 in the XML file) to account for any discrepancies from the previous VAT return.

  3. Contact SPF Finances for assistance in handling corrections.

The coaching session on tax management was excellent, good material, excellent explanations and very insightful. Combined with the AI I never feel alone with Accountable.

The availability of your team to help and guide people to understand their finances better is what really makes Accountable valuable. While the AI is able to give answers to most basic questions, specific scenarios need counsel from a human which your team performs beautifully.

They always answer for questions wherever is via direct e-mail or through app. If they can’t answer fully they will forward you to the right place. Documents were always prepared well and ready to send further to government. Everything is intuitive in the app and easy to sort out even for someone completely green in this field.
