Side hustles: the trading allowance triples

From 6 April 2027, the trading allowance rises from £1,000 to £3,000, and so does the point at which you need to tell HMRC about trading income. If you earn up to £3,000 a year from selling, making or small gigs, it is tax free and does not need reporting.

Above £3,000 you can still choose between the allowance and your actual expenses. The calculator below now has a 2027/28 setting.

The Making Tax Digital timetable is unchanged: £30,000 from April 2027 and £20,000 from April 2028. HMRC will not give penalty points for late quarterly updates in 2027/28 to people joining in April 2027.

ISAs: the cash ISA cut is cancelled

The plan to limit under-65s to £12,000 a year in cash ISAs from April 2027 has been reversed. You can keep putting the full £20,000 into cash ISAs. The Budget also dropped a planned charge on uninvested cash in stocks and shares ISAs, according to Which?.

Savings and property: higher tax rates

From 6 April 2027, income tax on savings interest and property income rises to:

Higher rate40%44%
Additional rate45%49%

Savings interest inside your Personal Savings Allowance, and inside an ISA, stays tax free. Income under the Rent a Room scheme stays tax free up to £7,500.

First-time buyers

  • A new First Time Buyer ISA replaces the Lifetime ISA for new savers from April 2029, with up to £4,000 a year and a 25% bonus. Existing Lifetime ISAs carry on.
  • The penalty for using a Lifetime ISA on a home over the £450,000 cap falls from 25% to 20%, from 29 October 2026.

Work and pay

  • The National Living Wage rises by 3.9% to £13.21 an hour for over-21s, and to £11.27 for 18 to 20 year olds, from April 2027.
  • From April 2029, people who make payments on account will make more regular, automated payments through the year instead of two large ones.

What to do now

  1. Side hustlers: if you earn between £1,000 and £3,000, your 2027/28 income will not need reporting. You still need to report 2025/26 and 2026/27 as normal.
  2. Savers: use your ISA allowance, especially if your savings interest is above your Personal Savings Allowance.
  3. Landlords: budget for the higher tax rate on rental profits from April 2027.
