How to avoid tax on £80,000 savings

With £80,000 in savings, you cannot shelter everything in an ISA in a single year (the allowance is £20,000). But over 4 years of maximum ISA contributions, you could move the full balance into a tax-free wrapper.

In the meantime, prioritise moving your highest-rate savings into ISAs first to maximise the tax saving.

Other strategies to reduce tax on savings interest:

  • Use your ISA allowance — £20,000 per year, completely tax-free
  • Spread between partners — Each person has their own PSA. If one partner is basic rate (£1,000 PSA) and the other is higher rate (£500 PSA), hold more savings in the basic rate partner's name
  • Premium Bonds — Returns are tax-free (prizes instead of interest). Average "prize rate" around 4%
  • NS&I products — Some National Savings products offer tax-free returns
See ISA returns on £80,000 for a detailed comparison.

At what savings level do you start paying tax?

At 4.5%, the PSA breakeven points are:

  • Basic rate (£1,000 PSA): Tax-free on savings up to £22,222
  • Higher rate (£500 PSA): Tax-free on savings up to £11,111
  • Additional rate (£0 PSA): Tax on all savings interest from £1
Your £80,000 exceeds the basic rate threshold of £22,222, so all taxpayers will pay some tax on the interest at 4.5%.
