When you submit your quarterly VAT return on Intervat, it may happen that you get an error code.

How to deal with those error codes?

In the table below, you will find the recurring error codes and how to correct 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 value in cell 56 or 57 is 0€ → This is most likely due to an incorrect encoding of outside-EU expenses.

Double check 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 sum of cells 81 to 85 → possibly due to wrong encoding of expenses, or import tax?

Double check encoding of expenses

VAT return

W_TVA_GRID_55_INCORRECT_VALUE

Grid 86/88 vs. 55

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

Double check encoding of intra-EU purchases

VAT return

W_TVA_GRID_PRESENCE_444648

Warning message to remind users to also submit the intracom listing

The VAT return shows income from intra-EU clients

Submit intracom listing for the quarter

VAT Return

W_TVA_GRID_00_SUM_INCORRECT_VALUE

The amount of transactions subjects 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. As the sale of your business is a large amount, this amount will probably be higher in the declaration in cells 81 to 85.

It's enough to justify it in the tab on intervat by 'putting sale of business according to article 11 VAT code'. You can also add the sales invoice in the tab 'justify' on intervat.

VAT Return

E_DECLARATION_EXIST_FOR_SAME_PERIOD

A VAT return was already submitted for the same period

Most likely, you want to file a correction

Follow the process from the Help Center Article

VAT Return

E_VATNUMBER_NOT_RECORDED

VAT return cannot be submitted.

The VAT number you entered is not currently recognized 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, you must fill out and submit the 604A form online:

https://finance.belgium.be/en/enterprises/vat/declaration/registration-change-cancellation-activity

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

For confirmation or assistance, we recommend contacting FPS Finance or your business counter.

When you submit your annual client listing on Intervat, it may happen that you 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.
