What the New Rates Mean in Pounds
Here's a simple example for a landlord with £12,000 of rental profit, all of it taxed at the same rate. In 2026-27, rental profit is taxed at 20%, 40% and 45%.
- Basic rate: £2,400 now, rising to £2,880 at 24%, which is £480 more
- Higher rate: £4,800 now, rising to £5,280 at 44%, which is also £480 more
- Additional rate: £5,400 now, rising to £5,880 at 49%
Allowable expenses still reduce your profit as they do now, so your own figures will differ.
How Payments on Account Could Change
If your last Self Assessment bill was more than £1,000, and less than 80% of your tax was taken at source, HMRC usually asks for payments on account. These are two advance payments towards your next bill, due on 31 January and 31 July, each normally half of your previous year's bill.
They're based on your whole Self Assessment bill, so rental and savings income count as well as self-employed profits. A bigger 2027-28 bill can therefore push up the payments on account you make for 2028-29. If your income falls, you can ask HMRC to reduce them, but if you cut them too far you'll pay interest on the difference.
A Quick Checklist
- Work out your rental profit and savings interest for 2026-27
- Estimate what they'd cost at the new rates from 6 April 2027
- Check whether your qualifying income brings you into Making Tax Digital from April 2027
- Set aside a little extra each month for the higher bill
- Keep this year's bank statements and letting agent summaries together, ready for your return
