As an independent in Belgium, you have to submit your VAT return periodically. This declaration contains a summary of VAT you’ve collected yourself via your sales invoices, and VAT you’ve paid on your professional purchases. Your VAT balance is calculated based on this return, and you find out whether you’re entitled to a VAT refund or have to pay.

In this guide, we take you step-by-step through the VAT return: from preparing it to submitting it via Intervat, to paying the outstanding balance. Let's go!

Deadline for filing VAT returns

The periodic VAT return can be submitted either through a monthly return or a quarterly return.

• Quarterly return if you earn less than 2,500,000 euros (excluding VAT).
• Monthly VAT return if you earn more than 2,500,000 euros (excluding VAT).

Your VAT return or quarterly return must be submitted between the 1st and the 25th of the month following the quarter for which you need to file.

Note these VAT return deadlines in your calendar:

27-04-2026: payment and return for Q1
25-07-2026: payment and return for Q2
25-10-2026: payment and return for Q3
25-01-2027: payment and return for Q4

Step 1: Prepare your VAT return

Follow the step-by-step guide below to submit your VAT return quickly and easily yourself.

If you work with an accountant, chances are they’ll prepare your VAT return and maybe even submit it for you. It’s important to agree on this up front with your accountant to avoid any surprises.

Do you keep track of your VAT expenses and income yourself? In that case, grab them now, because in the next step, we’ll start working with them!

If you have systematically kept track of all your income and expenses in Accountable, you’ll be able to create the VAT return in just a few clicks. That saves you a lot of time and work. Easy, right?

Are you an Accountable user?

First, check that all your income and expenses are in Accountable. The best way is to prepare your sales invoices in Accountable or upload them systematically. The same goes for all receipts and purchase invoices; add them as soon as you receive them. 

In the web version of Accountable, go to the 'Taxes' tab.

• Go to the quarter for which you want to file the return, then click on 'VAT' and select 'Review and Submit'.

• Check your income and expenses. Our app automatically detects possible errors and may ask you to review certain items, such as expenses or transactions. Everything okay? Then click on 'Continue'.

Step 2: Submit to the FPS Finance (Intervat)

Now that you’ve passed all the checks, it’s time to submit your VAT return. You can do this with just one click, directly from our app.

Next, a quick authentication will follow to give Accountable permission to submit your VAT return via Intervat.

• Choose your preferred login method, for example "Itsme".
• Follow the authentication process, scroll down and tick “I accept.”
• Then click “Agree.”

Yes! Your VAT return has now been submitted to Intervat.

You can view your submitted VAT return at any time via the ‘Submissions history’ button (clock icon) at the top right of your screen.

Would you like to check yourself if your VAT return has been successfully received by the FPS Finance?

There are two ways to do this:

• Option 1: Log in to Intervat on behalf of your company. You can then view your VAT return under "My declarations". If the status shows "Success", your VAT return has been successfully received.

• Option 2: Log in to MyMinfin on behalf of your company. Under "Mes documents" (FR) or "Mijn documenten" (NL) you will find the receipt confirmation of your return.

Step 3: Pay your VAT balance (if necessary)

After successfully submitting your VAT return, you’re not quite finished yet.

Do you need to pay VAT?

• Go back to Accountable.
• Pay your VAT balance via the QR code.
• Mark your VAT return as submitted and paid.

Will you get a VAT refund?

In that case, you don’t need to do anything; the money will automatically appear in your account.
