How to avoid tax on £30,000 savings
With £30,000 in savings, you cannot shelter everything in an ISA in a single year (the allowance is £20,000). But over 2 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
