From April 2027, rental income faces an extra 4 percentage points of income tax, according to Budget coverage in This is Money.
That is on top of the earlier rise announced by Reeves. It applies to rental profit and savings interest above your personal allowance.
So this is not a tweak to the rate. It is a surcharge stacked on a surcharge, and it lands on income you are already receiving from tenancies you signed years ago.
Worth being precise about what it hits. Not turnover. Rental profit, after allowable costs, with finance costs still only getting the 20% tax credit under Section 24 (the rule that stopped full mortgage interest relief).
For a higher rate landlord with a mortgage, that credit was already doing a lot of heavy lifting. Another 4 points on the gross figure changes what is left at the bottom.
Most people will model this on their next purchase. The bigger number is sitting in the properties you already hold.
Run one existing property through it. Current profit, current rate, then the 2027 rate. If the answer surprises you, the other ones will too.
An accountant should confirm your own position before you act on anything.
Which property in your portfolio would you check first?
