Cash ISA

HSBC e-ISA customers should diarise to transfer their cash as the bank has confirmed interest rates will tumble from October.

Over one-and-a-half million Barclays NISA customers will see their rates drop this autumn as the bank will be moving most of its old NISA customers onto a new deal.

If you've taken advantage of your tax-free ISA allowance every year since the accounts were introduced in 1999, you should check how much you've saved as you may now have breached the UK's £85,000 safe savings limit.

ISAs transform into NISAs (New ISAs) today, meaning everyone can now put £15,000 into cash or shares savings without paying tax on it.

16 and 17-year-olds can save up to £19,000 tax-free this year under today's ISA revamp, meaning they could net £100s in interest if they put the maximum amount away.

Savers torn between easy-access, fixed cash and regular saver ISAs can now open one of each in the same tax year at certain building societies and banks and still earn top rates, MoneySavingExpert.com has discovered.

If you opened a Santander Direct ISA Saver last year, check your rate now. If you haven't upgraded, it could now be paying as little as 0.5%.

Savers can get up to 2.75% tax-free interest on cash put into an ISA. But with the deadline looming you need to use your ISA allowance now or you'll lose it.

Chancellor George Osborne announced big changes for the UK's savers in today's Budget, including a revamp of the Isa system and new bonds for over-65s.
