When you submit your quarterly VAT return on Intervat, you may get an error code. The table below lists the recurring error codes and how to correct them in Accountable.

Please note that this article provides general guidance only. Tax rules may vary depending on your individual situation. When in doubt, ask your Tax Coach.

​

How to deal with those error codes?

In the table below, you will find the recurring error codes and how to correct them in Accountable:

Error code

Issue

Root cause

Solution

VAT return

W_TVA_GRID_5657_INCORRECT_VALUE

Grid 5657 incorrect value

There are values in cell 87, but the value in cell 56 or 57 is 0€. This is most likely due to an incorrect encoding of outside-EU expenses.

Double-check the encoding of expenses.

VAT return

W_TVA_GRID_59_INCORRECT_VALUE

Grid 59 incorrect value

The amount in cell 59 is higher than 21% VAT from the sum of cells 81 to 85. This may be due to incorrect encoding of expenses or import tax.

Double-check the encoding of expenses.

VAT return

W_TVA_GRID_55_INCORRECT_VALUE

Grid 86/88 vs. 55

There are values in cell 86/88, but the value in cell 55 is 0€. This is most likely due to an incorrect encoding of intra-EU expenses. It may also happen that one provider is not eligible for reverse-charge and therefore charged 0% VAT.

Double-check the encoding of intra-EU purchases.

VAT return

W_TVA_GRID_PRESENCE_444648

Warning message reminding you to also submit the intracom listing

The VAT return shows income from intra-EU clients.

Submit the intracom listing for the quarter.

VAT return

W_TVA_GRID_00_SUM_INCORRECT_VALUE

The amount of transactions subject to special arrangements (grid 00) is greater than the total of transactions in grids 81 to 85.

This often happens when you sell your business as a whole. Because the sale represents a large amount, it will likely be higher in the declaration in cells 81 to 85.

Justify it in the tab on Intervat by entering "sale of business according to article 11 VAT code". You can also add the sales invoice in the "justify" tab on Intervat.

VAT return

E_DECLARATION_EXIST_FOR_SAME_PERIOD

A VAT return was already submitted for the same period.

You most likely want to file a correction.

Follow the process described in our how to submit a VAT return correction article.

VAT return

E_PERIOD_IN_THE_FUTUR

The period must be closed before filing a VAT return.

You are most likely trying to submit a VAT return for a quarter that has not been closed yet.

Wait until the first day of the month following the end of the quarter to submit the VAT return.

VAT return

E_TVA_DECLARANT_REGIME_NOT_ALLOWED

VAT return cannot be submitted.

You are a franchisee.

⚠️ You may have mistakenly charged VAT on sales invoices.

Or your VAT number may not have been active during the selected period.

Do not submit the VAT return. Update your account settings and catch up on past revenue and invoices in your accounting.

Or contact the relevant administrative body (such as your business counter or the FPS Finance) to verify your VAT status.

VAT return

E_VATNUMBER_NOT_RECORDED

VAT return cannot be submitted.

The VAT number you entered is not currently recognised by Intervat. This usually means that your VAT registration is either not yet completed or still being processed by the authorities.

To activate your VAT number, fill out and submit the 604A form on the FPS Finance website.

If you have already submitted this form, allow a few days for the activation to appear in Intervat.

For confirmation or assistance, contact FPS Finance or your business counter.

When you submit your annual client listing on Intervat, you may get this error code:

Client listing

E_Year_Invalid

Client listing is from the wrong year.

You are uploading the current year's client listing. This is only possible if you are closing your VAT number.

Nothing to do.

​

Key takeaways

  • Most Intervat error codes point to an incorrect encoding of expenses or purchases in Accountable: always double-check your entries first.

  • If a VAT return was already submitted for the same period, follow the correction process rather than resubmitting.

  • You can only submit a VAT return from the first day of the month after the quarter closes.

  • If your VAT number is not recognised by Intervat, submit the 604A form and allow a few days for activation.

  • The E_Year_Invalid error on the client listing means you are uploading the current year's listing, which is only permitted when closing your VAT number.

They always answer right away to any question I have, they provide clear answers, and they are very patient even when I struggle to understand. They try to explain in different ways. They are very helpful, responsive and friendly.

This program is a lifesaver, and it is always improving. Plus, it has an AI chat feature that is actually useful.

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.
