There are some big changes to ISA limits in the 2014/15 tax year. In particular ISAs will change with effect from 1 July 2014 both in the amount you can save and the way you can save it.
So in general the ISA limit from 6 April 2014 is that you can pay £5,940 into a cash ISA and the total amount you can pay into both stocks and shares, and your cash ISA is £11,800.
Then on 1 July 2014 the name will change to a New Individual Savings Account (NISA) and the combined limit on cash and stocks and shares NISAs is £15,000 – this amount includes any money that you have paid into your old ISAs after 6 April 2014.
All old ISAs will be renamed NISAs from 1 July but cash and stocks and shares can be held within the same NISA.
