Why the sums changed in 2025
Until April 2025, furnished holiday lets had their own tax rules. Owners could deduct all their mortgage interest, claim capital allowances on furniture and pay less capital gains tax on a sale. Those rules have gone. A short let is now taxed like any other rental, so the comparison comes down to what's left after the extra running costs.
What eats into short-let income
Platform fees typically take around 15% if you pay the host-only fee. Each changeover needs a clean and fresh laundry, so shorter stays cost more per night. You also pay the bills, broadband, council tax or business rates, and replace worn furnishings. A long-let tenant normally covers bills and council tax themselves.
Worked example
A flat outside London that would long-let for £1,850 a month, short-let at £165 a night and booked 70% of the year, keeps its owner about £2,200 a year more as a short let after tax. That's before counting the time spent on messages, check-ins and reviews. Tick the London box and the 90-night limit puts the short let far behind.
Questions landlords ask
Is Airbnb income taxed differently from normal rent?
Not since April 2025. Short-let profit is taxed as property income, mortgage interest gets only the basic-rate credit, and capital gains on a sale are taxed like any other rental.
What is London's 90-night rule?
Letting a whole home in London for more than 90 nights a year needs planning permission. The limit counts nights across all platforms and direct bookings.
Will I pay council tax or business rates?
To pay business rates, the property must be available for at least 140 nights a year and actually let for at least 70. Otherwise it pays council tax, and councils can charge up to double on second homes.
Do I need my lender's permission?
Usually. Most buy-to-let mortgages and many leases don't allow short lets. You may need a holiday-let mortgage, your freeholder's consent and specialist insurance.
