When to Declare Airbnb VAT in Belgium: Payout Date, Not Booking Date

Many Belgian Airbnb hosts and their accountants assume that VAT on rental income should be declared based on the guest's booking date. This is incorrect. Under Belgian VAT law, the cash-basis system (incasseringsstelsel) applies: VAT becomes chargeable when the host receives payment from Airbnb — the payout date.

This article explains the Belgian VAT chargeability rules as they apply to Airbnb short-term rental, the 6% to 12% rate transition of March 2026, and the transitional measure for reservations made before the rate change.

Belgian VAT chargeability: when does VAT become due?

Under Belgian VAT law (the Wetboek BTW), the chargeability of VAT — called opeisbaarheid — depends on three events:

Since 1 January 2016, VAT becomes chargeable at the earlier of the invoice date or the payment date. The taxable event (completion of service) only determines when the invoice must be issued — it is no longer the primary trigger for chargeability.

B2C: the cash-basis system (incasseringsstelsel)

For B2C transactions — which is the vast majority of Airbnb bookings, since guests are private individuals — the host is generally not obliged to issue an invoice. In this case, the incasseringsstelsel applies under Article 22bis, §3 of the Belgian VAT Code (W.BTW): VAT becomes chargeable when payment is received.

A voluntarily issued invoice does not trigger chargeability on its own. The tax administration does accept that hosts who voluntarily issue invoices may use the invoice date, but only as an administrative tolerance, applied consistently across all invoices.

How this applies to Airbnb rentals

Understanding the Airbnb payment timeline is critical:

The booking date is when the guest reserves — no service has been performed and no payment has been received by the host. It has no VAT significance, except for the 6% → 12% transitional rule (see below).

For most Airbnb hosts (B2C, no mandatory invoice), revenue should be recognized for VAT purposes at the moment the host receives the payout from Airbnb. This is the cash-basis system. The VAT becomes chargeable when the money arrives.

Long stays (28+ nights)

For reservations of 28 nights or longer, Airbnb collects payments from the guest on a monthly basis and releases payouts to the host monthly. This creates multiple VAT chargeability moments for a single reservation — each payout is a separate VAT event. Hosts must account for each payout individually.

What amount is subject to VAT?

The VAT base for Airbnb rental income includes:

• The nightly rental rate
• Cleaning fees charged to the guest
• Any other fees charged to the guest (extra guest fee, etc.)
• Including the Airbnb host service fee (the commission Airbnb retains)

The total amount the guest pays for the accommodation (minus the guest service fee which Airbnb charges separately to the guest) forms the VAT base. The host must declare VAT on the full amount including Airbnb's commission, even though they never receive that portion in cash.

The 6% to 12% VAT rate change (1 March 2026)

As of 1 March 2026, the VAT rate for furnished accommodation (gemeubeld logies) and camping pitches increases from 6% to 12%. This applies to all short-term Airbnb rentals in Belgium.

Which rate applies?

The applicable rate is determined by when the VAT becomes chargeable (opeisbaar) — that is, the payout date:

Transitional rule

The minister has provided a transitional measure: for reservations made on or before 28 February 2026, the 6% rate continues to apply, provided that the VAT becomes chargeable (i.e. the host receives the payout) by 30 June 2026 at the latest.

The transitional rule does not apply to:

• Reservations made from 1 March 2026 onwards (always 12%)
• Reservations made before 1 March 2026 where the payout is received on 1 July 2026 or later (12%)

The host must be able to prove the reservation date (e.g., confirmation email or proof of deposit payment).

Practical examples

How accountants handle this in practice

Based on the practices of Belgian accounting firms:

• Small hosts using a dagontvangstenboek (daily receipts book): record each payout on the day the money is received. VAT is calculated on the full amount including platform commission.
• Larger hosts / accountants using Exact Online: create a sales journal entry for each reservation. The entry date is the payout date. The VAT amount is calculated on the gross rental amount (before Airbnb deducts its commission).
• Airbnb commission: booked as a separate cost line (usually ~3% host fee), with the VAT on the commission as input VAT (aftrekbare btw) since Airbnb invoices the host from Ireland (reverse charge / intracommunautaire dienst).
• Quarterly VAT return: all reservations with payouts in the quarter are included. The return is filed by the 20th of the month following the quarter.

Key takeaways

1. VAT on Airbnb rental income becomes chargeable at the payout date (when the host receives money from Airbnb), not the booking date or stay date.
2. The VAT base includes the full guest payment for accommodation, including the Airbnb host service fee.
3. The 6% → 12% rate transition is determined by the payout date, with a transitional rule for pre-March 2026 reservations (payout must be received by 30 June 2026).
4. Long stays (28+ nights) create multiple VAT events — one per monthly payout.
