Cash Isa deals of the week 26 March 20152014/15 Isa deadline fast approaching

26 March 2015

With the deadline to put money into your tax-free cash Isa account just over a week away, Which? provides our weekly look at the best deals out there.

Cash Isa deadline is 5 April 2015

The cash Isa deadline is important as it signifies the end of the tax year. You'll lose this year's tax-free savings allowance if you haven't put money into an Isa before that date.

Each year you can deposit your savings into a cash or a stocks and shares Isa, or both. The overall limit for the tax year ending 5 April 2015 is £15,000 (for both cash and stocks & shares) and this goes up to £15,240 for the new tax year of 2015/16 starting 6 April 2015. 

In his 2015 Budget, Mr Osborne announced that savers will be able to take out and put money back into their cash Isa without it counting towards their annual tax-free Isa entitlement for that tax year. These changes will be introduced in Autumn 2015.

To maximise your tax-free allowance, remember to save in a cash Isa before putting your money in an ordinary taxable savings account.

Here, we take a look at some of the best cash Isa deals currently available. For the Best Rate cash Isas, we've also included a link to the Which? Money Compare tables where you can find out more details.
