Preparing a Belgian VAT return involves more than adding up invoices. The correct reporting period, VAT treatment and a well-organised set of records all matter. This checklist helps you prepare before submission.
This article concerns businesses subject to periodic Belgian VAT returns. Special exemption schemes and particular types of activity may have different obligations.
1. Confirm which VAT scheme applies
Most businesses under the standard VAT regime file periodic returns, either monthly or quarterly according to the relevant rules. Some qualifying small businesses may use a VAT exemption scheme with different requirements. Exemption does not necessarily mean there are no administrative obligations.
Ask your accountant to review your VAT regime when turnover, activities or cross-border transactions change. See the Belgian Federal Public Service Finance.
2. Collect all sales and purchase invoices
Gather outgoing invoices, credit notes and incoming supplier invoices. Check the correct period and look for missing or duplicate records.
- Have all sales invoices and credit notes been included?
- Are supplier invoices complete and assigned to the correct supplier?
- Is the VAT treatment correct for each type of good or service?
- Have foreign purchases and sales been reviewed separately where necessary?
- Do you need clarification from any supplier?
3. Distinguish costs from deductible input VAT
An expense incurred for business purposes is not automatically fully deductible for VAT. The nature of the expense, how it is used and your business’s entitlement to deduction all matter. Mixed private and business use and certain statutory limitations require particular care.
4. Record the deadlines and check the current calendar
For monthly VAT filers, the ordinary payment deadline is generally the twentieth day of the following month. The Belgian VAT chain reform sets the ordinary quarterly deadline at the twenty-fifth day of the month after the quarter. Specific submission and payment dates can be affected by calendars and exceptions.
Check current Belgian VAT payment guidance and agree on a document-submission date well before the official deadline.
5. Review Peppol and e-invoicing
Since 1 January 2026, many domestic B2B transactions in Belgium require structured electronic invoices. This can make exchange easier, but it does not automatically ensure correct VAT codes or eliminate the need for controls. Read our article on Peppol and e-invoicing in Belgium.
6. Resolve open questions before submitting
List unusual invoices, corrections, uncertain VAT categories and foreign transactions. Provide clear explanations to your accountant rather than guessing. A filing obligation may apply even when no VAT is payable.
Frequently asked VAT questions
Does every self-employed person file quarterly?
No. Requirements depend on the applicable VAT regime and activity. Some businesses file monthly; others quarterly; special schemes work differently.
Can I recover VAT on every business expense?
No. The right to deduct input VAT can be restricted or excluded. Consider this separately from whether the cost qualifies for income tax purposes.
What if I forgot an invoice?
Contact your accountant promptly. Corrections depend on the transaction and applicable rules.
