The VAT return is one of the most important tax obligations for any VAT-registered business in Belgium. Whether you are a sole trader, or you manage an SRL or an SA, you must regularly declare VAT collected and deductible to FPS Finance (SPF Finances). This detailed guide walks you step by step through completing, filing and checking your Belgian VAT return.
Who must file a VAT return in Belgium?
Under the Belgian VAT Code (articles 50 to 55), every business registered for VAT must file periodic returns. This covers:
- Sole traders carrying out an economic activity subject to VAT
- Companies (SRL, SA, SC, SNC, SCS) established in Belgium
- VAT groups formed by several related entities
- Foreign businesses with a permanent establishment in Belgium, or required to register there
Exceptions: businesses under the VAT exemption scheme (annual turnover below EUR 25,000) do not file a periodic return, but must submit an annual list of VAT-registered customers and an annual listing.
Monthly or quarterly return: how to choose?
The quarterly return
The quarterly return is the default regime for businesses whose annual turnover (excl. VAT) does not exceed EUR 2,500,000. The filing deadlines are:
| Quarter | Period covered | Filing deadline |
|---|---|---|
| Q1 | January–March | 20 April |
| Q2 | April–June | 20 July |
| Q3 | July–September | 20 October |
| Q4 | October–December | 20 January (following year) |
The monthly return
The monthly return is mandatory in the following cases:
- Annual turnover above EUR 2,500,000
- Intra-Community supplies exceeding EUR 400,000 a year
- Certain specific activities (energy products, manufactured tobacco)
It is optional for any business wanting to recover VAT credits more quickly. The deadline is the 20th of the month following the period concerned.
Practical tip: if your business regularly generates VAT credits (exports, reduced rate on sales but standard rate on purchases), switching to the monthly regime lets you recover your credit every month instead of waiting until the end of the quarter.
The December advance payment
Quarterly filers must pay a VAT advance payment by 24 December each year at the latest. This advance corresponds to the VAT due on October and November transactions. It is entered in grid 91 of the Q4 return.
Understanding the grids on the Belgian VAT return
The Belgian VAT return is made up of several numbered boxes and grids. Here is the full breakdown:

Worked example: completing a quarterly VAT return
Take the example of Sophie, a self-employed web developer in Brussels, registered under the quarterly regime.
Her transactions for Q1 2026:
Sales:
- Website development for a Belgian SME: EUR 5,000 excl. VAT (21%)
- Maintenance for a Belgian client: EUR 1,200 excl. VAT (21%)
- Website creation for a French company (B2B): EUR 3,000 excl. VAT (reverse charge)
Purchases:
- Hosting subscription (Belgian supplier): EUR 150 excl. VAT (21%)
- IT equipment (laptop): EUR 1,800 excl. VAT (21%)
- Adobe software subscription (Irish supplier): EUR 180 excl. VAT (reverse charge)
- Shared office rent: EUR 600 excl. VAT (21%)
- Accountant's fees: EUR 450 excl. VAT (21%)
Completing the grids:
| Grid | Amount | Calculation |
|---|---|---|
| 03 | EUR 6,200.00 | 5,000 + 1,200 |
| 44 | EUR 3,000.00 | Intra-Community services |
| 54 | EUR 1,302.00 | 6,200 x 21% |
| 82 | EUR 1,200.00 | 150 + 600 + 450 |
| 83 | EUR 1,800.00 | Laptop (capital good) |
| 87 | EUR 0.00 | – |
| 88 | EUR 180.00 | Adobe subscription |
| 55 | EUR 37.80 | 180 x 21% |
| 59 | EUR 667.80 | (1,200 + 1,800) x 21% + 37.80 |
| 71 | EUR 634.20 | 1,302.00 + 37.80 – 667.80 – 37.80 |
Sophie must pay EUR 634.20 to FPS Finance before 20 April 2026.
How to file your VAT return via Intervat
Step 1: Accessing the platform
Log in to Intervat using:
- eID (Belgian electronic identity card with card reader)
- itsme (Belgian authentication app)
- A digital certificate (class 3)
Step 2: Creating the return
You have two options:
- Manual entry: enter the amounts directly into the grids via the Intervat web interface
- XML file upload: most accounting software packages (Horus, WinBooks, BOB50, Octopus, Yuki, Dexxter) generate an XML file compliant with the Intervat schema. Simply import it.
Step 3: Validation and checking
Before submitting, check:
- The consistency between the output grids and the VAT due (grid 54 = 6% of 01 + 12% of 02 + 21% of 03)
- The match between grids 86/88 and grid 55
- The overall balance of the return
- That amounts are correctly rounded to the euro cent
Step 4: Submission and acknowledgement of receipt
After submission, Intervat generates an acknowledgement of receipt (PDF), which you must keep. This document proves the return was filed on time.
Step 5: Payment
If the return shows a balance in grid 71 (VAT payable), payment must be made to the FPS Finance VAT current account:
- IBAN: BE22 6792 0000 0150 (BNP Paribas Fortis)
- Structured reference: provided by Intervat when you file
Note: since 2023, FPS Finance has used a VAT current account system. Payments and refunds are centralised on this account. A VAT credit is first applied to any other outstanding tax debts before being refunded.
The most common mistakes and how to avoid them
1. Confusing grids 81, 82 and 83
- Grid 81: goods intended for resale or processing
- Grid 82: services and miscellaneous goods (office supplies, rent, fees, telecoms)
- Grid 83: capital goods (useful life over 1 year, depreciable)
Common mistake: entering an EUR 1,800 laptop in grid 82 instead of grid 83. Capital goods (generally over EUR 1,000 excl. VAT) belong in grid 83.
2. Forgetting the reverse charge on intra-Community services received
When you buy a service from an EU provider (web hosting from an Irish supplier, Google Ireland advertising, etc.), you must:
- Enter the amount in grid 88 (input)
- Calculate the Belgian VAT due in grid 55
- Deduct that same VAT in grid 59 (if you have full deduction rights)
The operation is financially neutral, but forgetting it can result in a fine.
3. Not declaring credit notes
Credit notes must always be declared in the appropriate grids (48, 49, 84, 85). Failing to declare them skews the return and can lead to a tax reassessment.
4. Missing filing deadlines
Late filing results in administrative fines:
| Delay | Fine (first offence) | Fine (repeat offence) |
|---|---|---|
| 1 to 3 months | EUR 100 | EUR 200 |
| 3 to 6 months | EUR 200 | EUR 400 |
| More than 6 months | EUR 500 | EUR 1,000 |
In addition, late-payment interest of 0.8% per month (2026 rate) applies to VAT due that is not paid on time.
The replacement return and corrections
The replacement return
If you spot an error after filing, you can submit a replacement return via Intervat. It fully replaces the original return. There is no time limit, but it is best to correct it as soon as possible.
Correction via grids 61 and 62
For minor corrections, you can use:
- Grid 61: adjustment in favour of the State (you owe extra VAT)
- Grid 62: adjustment in your favour (you have paid too much VAT)
These grids are used in the return for the period in which the error is detected.
The annual listing of VAT-registered customers
In addition to periodic returns, every business must file, before 31 March each year, an annual listing of VAT-registered customers showing:
- The VAT number of each VAT-registered Belgian customer
- Total turnover generated with each customer (excl. VAT)
- Total VAT invoiced to each customer
This listing is filed via Intervat. Customers with total annual turnover below EUR 250 excl. VAT can be omitted.
The intra-Community statement
Businesses making intra-Community supplies of goods (grid 46) or intra-Community supplies of services (grid 44) must file an intra-Community statement. Its frequency follows that of the VAT return (monthly or quarterly).
For each EU customer, this statement shows:
- The customer's intra-Community VAT number
- The total amount of transactions
- The transaction code (L for supplies, S for services, T for triangular transactions)

VAT audits: how to prepare
FPS Finance regularly carries out VAT audits. If audited, you must be able to produce:
- All your sales and purchase invoices (originals) for 7 years (article 60 of the VAT Code)
- The sales and purchases journal
- The outgoing and incoming invoice book
- The VAT returns filed and acknowledgements of receipt
- Proof of payment of amounts due
- The capital goods register, for VAT revision purposes (article 48, para. 2 of the VAT Code)
Tip: scan and file your documents systematically. Electronic storage is accepted by FPS Finance, provided it guarantees the authenticity of origin, integrity of content and readability of the document.
Special cases
VAT groups
Since 2007, Belgium has allowed entities linked financially, economically and organisationally to form a VAT group (article 4, para. 2 of the VAT Code). Transactions within the group fall outside the scope of VAT. The group files a single consolidated return through a representative member.
The flat-rate scheme
Certain sectors (bakers, butchers, hairdressers, café owners, etc.) can opt for the flat-rate VAT scheme. The taxable base is determined on a flat-rate basis using fixed coefficients. This scheme is being phased out, and new businesses have no longer been able to choose it since 2028 (under the latest legislative proposals).
Mixed taxpayers
Businesses carrying out both transactions giving a right to deduct and exempt transactions (article 44 of the VAT Code) must apply a deduction ratio (prorata). The ratio is calculated as the proportion of turnover giving a right to deduct against total turnover. It is finally determined on 20 April of the following year.

- Check the consistency of your return before submitting it
- Keep your documents for at least 7 years
- Use accounting software that generates the Intervat XML file, to minimise errors
