How an Isa works and why you should have one
Each year in April, savers are given a fresh Isa allowance that qualifies for tax-free interest.
For the 2023/24 financial year, starting 6 April 2023 and ending 5 April 2024, the limit is £20,000.
Piggy five: We round-up the best tax-free deals – and it is slim pickings at the moment
You can transfer Isa money whichever way you wish between an investment account to savings account, whereas previously you could only shift it from saving to investments.
Cash Isa rates have been rising, along with non-tax free rates. It is worth opening one to shield money away from the taxman, especially with rates moving upwards.
Isa rules state you can only contribute to one Isa per tax year.
You can also transfer an old Isa for better returns. Here’s a quick guide to Isa saving.
It is possible to switch your current year’s cash Isa if you move the entire amount, but it is far simpler to get your choice right in the first place.
Rates are rising meaning the potential for a tax bill
The cash Isa savings market has seen considerable improvement over the past year off the back of Bank of England rate rises.
The best buy easy-access rates on a tax-free account pay more than 4 per cent. It also comes at a time as inflation races higher, leaving all savers with a serious headache.
Many may ask themselves why bother? Especially given that rates on non tax-free accounts are typically higher.
Yet when inflation is raging, it becomes even more important to make sure you are getting as much as you can from your savings.
An Isa is worth having, despite the tax-free savings interest allowance of £1,000 a year for basic rate taxpayers and £500 for higher rate taxpayers.
Essentially, with rates rising, more are likely to face a tax bill on their regular savings.
If you’re a basic-rate taxpayer earning 5 per cent interest, having more than £20,000 in savings will tick you over your PSA – and for a higher-rate taxpayer, that figure is £10,000.
Money sheltered in an Isa will deliver a tax-free income, even above that £1,000 level and if you are building up a long-term pot, you may one day be very grateful for that.
And who knows if the personal savings allowance will be around forever – it is much more likely to disappear than the Isa wrapper.
