The rise in interest rates over the past couple of years means more taxpayers are suffering tax on their savings– a problem few have had to worry about for years.
Millions are now affected.
Now with interest rates on savings on the way down, learning how to protect your savings from tax has never been more important.
We explain how savings are taxed, how much you might pay and how you can avoid paying tax on your savings.
This guide will cover:
How much interest on savings is tax-free?
Your tax-free savings allowance is largely determined by your income tax bracket – the highest rate of tax you pay on your income.
For basic-rate (20pc) taxpayers (who earn between £12,571–£50,270 is £1,000, meaning you can earn up to that amount in interest without paying tax.
This reduces to £500 for those who pay higher-rate (40pc) tax (earning between £50,271–£125,140). If you’re an additional-rate (45pc) taxpayer (earning more than £125,140), then all savings interest is taxable.
To help provide some context, to make £1,000 in interest in one year, you would need to have £20,000 in a savings account with a 5pc interest rate.
How to increase your tax-free savings allowance
You could shield even more of your savings from tax if your annual income is below £17,571. That’s because those with a lower income are eligible for the “starting rate for savings”. This is up to £5,000 of tax-free savings interest.
Those who earn less than £12,570 (the personal allowance) get the full benefit, but it decreases pound for pound when you earn above and beyond the allowance.
Therefore, by the time you earn £17,570 all of the extra tax-free allowance will be used up.
The 0pc tax rate on savings interest is intended as a savings incentive for those on lower incomes, but it can benefit well-off households, too – as long as one spouse earns less than £17,570.
How does the allowance work for couples?
As the tax break is granted at an individual level, irrespective of the higher-earning spouse’s income, it means the couple can cut their prospective tax bills by transferring savings to the lower-earning spouse.
This could work for couples where, for example, one parent is working full-time while the other has a part-time job and looks after the children. Alternatively, among couples in later life, one spouse may have retired on a good occupational pension while the other spouse receives a lower one.In cases where one spouse earns, say, £12,000 and the other earns £50,000, as a couple they could potentially earn up to £7,000 in savings interest before paying tax, were they to use the full allowances available to them – as long as the lion’s share of savings were held by the spouse with a lower income.
Alternatively, you could look at options to reduce your income tax band. Ways to do this include increasing your pension contributions, giving money to charity and taking advantage of salary sacrifice schemes.
