can I top up my isa now before end of tax year to gain intrest

bethA84

I have a cash isa can i top it up now to the maximum before the tax year ends as does the interest get paid based on the total amount in the isa on the 5th April ? 
allowing me to gain the most of this interest payment ? - then once the  interest has been paid can i look at taking if back out to invest in a higher rate fixed saving account.

No, interest is paid pro rata, i.e. money that's in there for a week will earn a week's worth of interest, rather than a year's worth!
