Do I have to self-invoice if Booking doesn't charge VAT on the invoice?

Yes, if you've given Booking a VAT number valid for intra-EU transactions: in that case the obligation to apply Italian VAT shifts to you, through an electronic self-invoice under the reverse charge mechanism, typically using document code TD17. It isn't optional: it follows from articles 17, paragraph 2, and 7-ter of Italy's VAT decree, DPR 633/1972.

What's the risk if I forget the self-invoice?

Since 1 September 2024, following the reform of Italy's tax penalty system, a fixed penalty from 500 to 10,000 euros if Booking's invoice is otherwise recorded in your accounts, or 5% of the taxable amount with a minimum of 1,000 euros if the transaction isn't recorded anywhere. Before the reform the ceiling was higher, 20,000 euros: if you've read that figure online, it's the superseded version.

If I don't have a VAT number, do I need to do anything about VAT on the commission?

No. Since 1 May 2023 Booking has registered for VAT in Italy and applies 22% directly on the commission invoice to anyone who hasn't provided a VAT number valid for EU transactions, paying that VAT to the Italian tax authorities itself.

Is Booking's commission a deductible cost?

For anyone operating as a business, yes: it's payment for a service actually rendered, so it counts as a cost inherent to the activity. For anyone renting without a VAT number, the answer depends on the tax regime: under Italy's flat-rate rental tax (cedolare secca) it's never deductible, because the tax is calculated on the gross rent; outside that regime, deductibility depends on the legal title under which you collect the rent, and it's worth checking with whoever handles your tax return.

Does the same mechanism apply to Airbnb or other platforms?

The reverse charge principle for services received from an EU supplier with no establishment in Italy is general, not specific to Booking. But the dates and percentages in this article are verified against Booking.com's own official sources: before applying them to another platform, check its specific position, because timing and conditions can differ.

Booking.com commissions: VAT and deductibility, with or without a VAT number

Q: Does reverse charge mean I pay VAT twice?

No. If your business normally deducts VAT on its purchases, the amount you self-charge through the invoice enters as both VAT payable and VAT deductible in the same settlement. The cash effect tends to be zero. What changes is the paperwork you have to do, not the tax you owe.

Whoever searches for how Booking commissions get declared has usually already worked out one thing: the invoice isn't the same for everyone. Everything hinges on a single question that almost no article puts first: have you given Booking a VAT number valid for intra-EU transactions, or not? That answer decides who applies VAT, what you need to do, and what's at risk if you don't.

One caveat: I'm not an accountant, I'm a digital consultant. What follows comes from verifiable sources, not from advice on your specific case.

With a VAT number: the invoice arrives without Italian VAT, and it's on you to close it out

Booking.com is a company based in the Netherlands. When you give it a VAT number valid for intra-EU transactions, the kind checked against the VIES system, the commission invoice arrives without Italian VAT: Booking.com states this itself in the dedicated section of its Partner Hub, explaining that in that case it's the property's responsibility to account for the tax (source: partner.booking.com, VAT on commission invoices section, checked 3 August 2026).

That responsibility has a precise name: reverse charge, or self-accounting. It's on you, not Booking, to calculate and pay the Italian VAT on that commission, through an electronic self-invoice. The code to use, according to the Italian Revenue Agency's technical specifications for electronic invoicing, is TD17, "integration/self-invoice for services purchased abroad": the same guide clarifies that submitting a document with this code fulfils exactly the integration obligation set out in article 17, paragraph 2, of DPR 633/1972 (source: Agenzia delle Entrate, Annex A to the technical specifications for electronic invoicing, version 1.7.1, checked 3 August 2026).

The basis for why the transaction still counts as taking place in Italy, even though the service provider is based in another EU country, is article 7-ter of the same decree: for "generic" services like an intermediary's, what counts is where the customer is based, meaning you. Put together, the two articles explain the whole mechanism: the commission is treated as rendered in Italy (7-ter), and if whoever invoices it has no establishment here, the obligation to apply VAT shifts to you (17, paragraph 2).

If you forget it

A missing self-invoice isn't a detail that goes unnoticed: cross-checking received invoices against VAT registers is enough to catch it. The penalty, since 1 September 2024, following the reform of Italy's tax penalty system, is smaller than what's often reported online: from 500 to 10,000 euros, when Booking's invoice is otherwise recorded in your accounts and only the VAT integration is missing. It rises to 5% of the taxable amount, with a minimum of 1,000 euros, if the transaction isn't recorded anywhere at all (source: article 6, paragraph 9-bis, of Legislative Decree 471/1997, as amended by Legislative Decree 87/2024).

If you find higher figures out there, up to a 20,000-euro ceiling, that's the version that applied before the reform, in force until 31 August 2024: it's no longer the current one.

The commission stays a cost, however the invoice arrives

Whether you receive it with or without VAT, the commission Booking retains stays a cost of your business: it's payment for a service actually rendered, certain in amount and documented by the invoice, so it's deductible from business income under the inherency principles tied to article 109 of Italy's income tax code (TUIR). It isn't a representation expense, which has different deductibility limits: it's a cost directly and specifically tied to booking revenue, not a generic promotional expense.

On the cash side, if your business normally deducts VAT on its own purchases, the reverse charge self-invoice tends to be neutral: the same figure enters as both VAT payable and VAT deductible in the same settlement. What changes isn't how much you pay, it's the extra paperwork not to forget.

If you don't have a VAT number

For anyone renting in a non-business capacity, without a VAT number, or without one valid for intra-EU transactions, the situation since 1 May 2023 is different and simpler on the compliance side: Booking has registered for VAT in Italy, and from that date applies 22% directly on the commission invoice, paying the tax to the Italian authorities itself. There's no reverse charge to do: Booking states this itself in its Partner Hub (source: partner.booking.com, VAT on commission invoices in Italy section, checked 3 August 2026).

On deductibility, generalising here is riskier than useful. If you've chosen the flat-rate rental tax (cedolare secca), the answer is clear: the taxable base is the gross rent, including whatever the intermediary retains as commission, and cedolare secca doesn't allow any kind of deduction, as the Italian Revenue Agency itself clarifies (source: Circolare 24/E of 12 October 2017, paragraph 3.1). Outside cedolare secca, deductibility depends on the legal title under which you collect the rent, whether you're the owner or a sublessor, and it's a technical distinction worth checking with whoever handles your tax return rather than generalising here.

The two situations, side by side

	With a VAT number valid for EU transactions	Without a VAT number
Who applies VAT on the invoice	No one: Booking invoices without Italian VAT	Booking, directly, since 1 May 2023
Rate	Whatever you apply yourself through the self-invoice	22%
What you need to do	Electronic self-invoice, reverse charge, code TD17	Nothing: Booking handles it
Risk if you forget it	Penalty from 500 to 10,000 euros, or 5% of the taxable amount (min. 1,000 euros) if not recorded	Not applicable
Is the commission deductible	Yes, as a business cost	Depends on the regime: never under cedolare secca

Where to start

The first check is to look at the last commission invoice you have on hand: is there a VAT line with an amount, or is it zero? If it's zero and you have a VAT number, check your purchase VAT register to see whether the reverse charge self-invoice actually exists, not just Booking's invoice. If it's missing, it's the moment to fix it before someone else points it out.

This article explains the mechanism, it doesn't replace whoever files your return: if you have doubts about your specific case, bring it to whoever handles your taxes, with this framework already in hand instead of starting from scratch.

If instead the question is how much the commissions really cost you, not just how they're declared, the Booking versus Airbnb comparison and the OTA commission calculator are the next step.
