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_PERIOD_IN_THE_FUTUR

The period has to be closed before filling in a VAT Return.

Most likely, you’re trying to submit a VAT return for a quarter that hasn’t been closed yet.

You need to 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

User is Franchisee.

⚠️ You might have mistakenly charged VAT on sales invoices.

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

Do not submit VAT return. Update account settings.

Catch up on the past revenue/invoices in accounting.

Or reach out to the relevant administrative team (such as your business counter or by contacting the FPS) to verify your VAT status.

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 here

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.

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.
