The periodic VAT return, your recurring appointment with the tax office
Every VAT-registered business in Belgium accounts to the tax office at regular intervals. The periodic VAT return is that appointment: period after period, it reports the VAT you charged your customers and the VAT you paid your suppliers, then produces the amount to pay the State or to reclaim. The balance is not an administrative footnote; it is where your cash flow meets your tax obligation.
Since 2025, the rules have shifted. The VAT chain reform moved one deadline, tightened corrections and created an automatic mechanism for latecomers. All the more reason to know exactly when and how to file.
This article sets out how the periodic return works: who files monthly or quarterly, the filing and payment deadlines, what the reform changed, and how to file through Intervat.
Monthly or quarterly filer: two regimes
Your filing rhythm depends on your profile. Monthly filing is the general rule: by default, a registered business files twelve returns a year. The lighter quarterly regime is an option, not an automatic right.
According to FPS Finance, you may opt for quarterly filing if your annual turnover does not exceed 2,500,000 euros excluding VAT. That ceiling drops to 250,000 euros excluding VAT for certain sensitive supplies (energy products, mobile phones, computers and their peripherals, motor vehicles subject to registration). Finally, the quarterly option is closed to a business required to file a monthly intra-community listing, meaning one whose intra-community supplies exceed 50,000 euros in a quarter.
| Monthly filer | Quarterly filer | |
|---|---|---|
| Returns per year | 12 | 4 |
| Default regime | ||
| Turnover ceiling | None | 2,500,000 EUR excl. VAT |
| Filing and payment deadline | 20th of the following month | 25th of the month after the quarter |
Filing and payment deadlines
The return and the payment share the same due date. For the monthly filer, it is the 20th of the month that follows the reported period: the January return is due by 20 February. For the quarterly filer, the VAT chain reform pushed the deadline to the 25th of the month after the quarter, up from the 20th previously.
In practice, a quarterly filer files four times a year: 25 April for the first quarter, 25 July for the second, 25 October for the third and 25 January for the fourth.

What the VAT chain reform changed
The law of 12 March 2023 modernising the VAT chain, whose entry into force was postponed to 1 January 2025, reworked several mechanisms of the periodic return. Three changes matter to a business day to day.
First, the quarterly deadline moves from the 20th to the 25th of the month after the quarter, giving five extra days to prepare the filing. Second, correction becomes stricter: a return can be amended only up to its deadline; after that date, the error is corrected in the next return rather than through a fresh submission. Third, the administration gains an automatic mechanism against non-filing: the substitute return.
Note that the reform does not touch advance payments. The quarterly advances and the December advance payment had already been abolished in earlier years, so you settle only the balance due at each deadline.
If you do not file: the substitute return
The reform also armed the administration against non-filing. If no return is submitted within three months of the deadline, FPS Finance issues a proposed substitute return. The amount is not symbolic: it equals the highest VAT due declared over the last twelve months, with a minimum of 2,100 euros.
That proposal is not final straight away. You keep a one-month window, running from the date it takes effect, to file your actual return. Once that window closes without a response, the proposed amount becomes payable. The message is clear: a prolonged omission costs more than a timely filing, even a provisional one.
Keep pace with your VAT returns
YouInv structures your invoices and VAT totals as you go, so you can prepare each periodic return without re-keying.
How to file through Intervat
Filing is electronic, through Intervat, the online service of FPS Finance. Paper filing is allowed only by exception, on justification. Two paths coexist in Intervat: manual entry of the boxes on screen, suited to modest volumes, and uploading an XML file generated by accounting software, safer as the number of transactions grows.
Before filing your return
Active VAT number
The business is identified and its filing regime (monthly or quarterly) is known.
Period totals closed
VAT collected and VAT deductible calculated from the invoices issued and received.
Intervat access
Authentication through eID, itsme or an agent, depending on your setup.
Up-to-date payment reference
The correct VAT provisions account number to pay the balance due.
Once Intervat accepts the return, keep the acknowledgement of receipt: it evidences the filing date. Any balance is paid separately, by the same deadline, using the structured reference provided.

When must you file your periodic VAT return in Belgium?
A monthly filer files and pays by the 20th of the month following the period. A quarterly filer has until the 25th of the month following the quarter, meaning 25 April, 25 July, 25 October and 25 January.
What is the difference between a monthly and a quarterly filer?
Monthly filing is the rule. The quarterly regime is an option open to businesses whose annual turnover does not exceed 2,500,000 euros excluding VAT, with a sub-threshold of 250,000 euros for certain sensitive goods and provided the business is not required to file a monthly intra-community listing.
How do you file a VAT return in Belgium?
The return is filed electronically through Intervat, the online service of FPS Finance, either by entering the boxes on screen or by uploading an XML file produced by your accounting software. Paper filing is allowed only by exception.
Does the December VAT advance payment still exist?
No. In Belgium the periodic VAT return no longer carries an advance payment: the quarterly advances and the December advance payment were abolished in earlier years, before the 2025 VAT chain reform. You now pay only the balance due at each filing deadline.
What happens if I do not file my VAT return?
If no return is filed within three months of the deadline, the administration issues a proposed substitute return equal to the highest VAT due declared over the last twelve months, with a minimum of 2,100 euros. You have one month to file your actual return before it becomes final.
