Rachel Reeves’s 2027 Tax Overhaul: What Savers Must Do Now

AI Summary
A series of tax reforms slated for April 2027 will slash cash ISA limits, raise rates on savings and rental income, and tighten the Making Tax Digital threshold. Financial advisers urge households to act now to preserve flexibility and minimise future tax bills.

The Upcoming 2027 Tax Landscape for Savers

From 6 April 2027 the UK government will introduce a package of changes that affect millions of taxpayers, from cash ISA allowances to the tax rates on interest, dividends and rental income. The reforms, announced by Chancellor Rachel Reeves, aim to narrow the tax gap between earned income and asset‑derived income.

Key Changes to Cash ISAs and Investment Allowances

  • Cash ISA cap: the annual cash‑only allowance drops from £20,000 to £12,000 for individuals under 65.
  • People aged 65 + retain the full £20,000 cash allowance.
  • Any contribution above the new cash limit must be placed in a stocks‑and‑shares ISA.
  • Making Tax Digital threshold falls from £50,000 to £30,000 for self‑employed and property income.
  • Higher tax rates on savings and rental income increase by 2 percentage points across all bands.

Financial Impact of New ISA Caps and Higher Income Tax Rates

The reduction in cash ISA capacity means that up to £8,000 of potential tax‑free savings per person will need to be moved into investment‑linked products. For basic‑rate taxpayers, the post‑reform savings tax rises to 22%, while higher‑rate and additional‑rate taxpayers face 42% and 47% respectively after allowances.

Illustrative impact:

  • A household saving £15,000 in a cash ISA this year would be forced to allocate £3,000 to a stocks‑and‑shares ISA.
  • Rental income of £10,000 previously taxed at 20% would rise to 22% for basic‑rate landlords.

How the Reforms Reshape Savings Behaviour and Property Markets

Advisors expect a surge in ISA transfers and a shift toward higher‑yielding investment vehicles as the cash‑ISA ceiling shrinks. The higher tax on rental income may accelerate the sell‑off of buy‑to‑let portfolios, prompting landlords to explore spouse transfers, corporate structures, or outright disposal.

Premium bonds, which remain tax‑free, could see renewed interest, especially given the current 3.3% prize‑fund rate.

Strategic Moves for Households Ahead of April 2027

  • Maximise the current year’s cash ISA allowance before it drops.
  • Consider regular direct‑debit contributions to spread cash flow and fully utilise both partners’ ISA limits.
  • Review ownership of savings; allocate cash to the lower‑taxed spouse where possible.
  • Evaluate the benefits of moving non‑ISA cash into premium bonds or other tax‑efficient products.
  • Landlords should model the impact of the higher rental tax and explore restructuring options well before the deadline.

Acting now, as advised by wealth‑management firms like Evelyn Partners, gives households the widest range of options and helps avoid a “use‑it‑or‑lose‑it” scenario when the 2027 reforms take effect.
