IAG’s €638 million Avios VAT dispute: Will Avios Become More Expensive?

IAG (the parent company of British Airways) is challenging how VAT applies to Avios. The outcome could have some unwelcome consequences for collectors. If HMRC wins, we could eventually see fewer Avios earned, less generous bonuses and potentially more expensive redemptions. IAG provided more detail in its Q3 results, which we covered on Friday.
In October 2024, HMRC issued a decision stating that IAG Loyalty must pay VAT at the standard 20% rate on Avios issued from March 2018 onwards.
HMRC argues that IAG Loyalty provides the services of developing, operating and maintaining the loyalty programme, so 20% VAT should apply regardless of how the Avios are used.
IAG disagrees, arguing that VAT should depend on what Avios are eventually redeemed for. Since most redemptions are flights, which are generally zero-rated for VAT, IAG has historically accounted for VAT on that basis.
IAG has paid €516 million to HMRC without admitting liability, with a further €122 million relating to VAT payments made since HMRC’s October 2024 decision (recorded separately in its accounts). Together, the amounts total €638 million, and the case is now heading to the tax tribunal.
The first-tier tribunal is scheduled for Q4 2026, with a decision anticipated in 2027.
Although IAG’s board doesn’t expect an adverse outcome, there’s clearly a lot at stake.
For Avios collectors, the concern is where that additional cost might eventually end up. If IAG loses, it could pass some of the cost on to its commercial partners, who may then pass it on to customers through lower earning rates, smaller welcome bonuses or fewer promotions. Some partners could even decide that offering Avios is no longer worthwhile.
There’s also the possibility of changes to redemption pricing or cash charges, although none of this has been announced.
And let’s face it, Avios collectors have already had their fair share of changes recently, particularly with the overhaul of the British Airways Club and the changes to earning and retaining status. The last thing members need is another reason to question whether they’re getting good value from their loyalty.
Of course, it’s important not to get ahead of ourselves. IAG is confident in its position, and even an unfavourable ruling wouldn’t necessarily mean an immediate change for members.
Our hope is that whatever happens, the cost doesn’t end up being passed on to the people who have spent years collecting Avios. Loyalty programmes only work when members feel they’re getting something worthwhile in return.
We’ll be following the case closely and will report on any developments.

AMEX Marriott Cashback Offer – Up to 20% Back

AMEX has launched a Marriott offer on selected cards. You can now receive £100 cashback when you spend £500 or more at participating hotels in Europe and the Middle East until 31st December 2026.
If you have a Marriott stay coming up, or you’re planning a trip, check that the offer is showing on your AMEX card and any supplementary cards you hold. It seems to be showing on a range of Platinum, Gold, BA, and business cards. Make sure you save the promotion to your card before spending; otherwise, you won’t qualify for cashback.
There’s a long list of participating hotels in 19 countries, including the UK, France, Spain, Italy and Greece, but make sure your chosen hotel is on the list before booking. View the full list here. You must also pay at the hotel.
You can spread the £500 spend across multiple transactions, rather than all at once. If two cards have the offer saved, you could potentially split a £1,000 hotel bill and receive £200 cashback.
If you hold a Marriott AMEX, there’s a more lucrative targeted promotion running of £70 back on £200 spend until 31st December. You can also combine the offer with Marriott’s latest global promotion of 1,500 bonus points on every qualifying paid stay of 2+ nights (plus an extra 3,000 points at participating resorts), as long as you remember to register before 13th November and complete your stay before 22nd November 2026.
