The deadline for using your annual ISA investment allowance is April 5th.  If it is your intention to invest money into an ISA before the end of this tax tear make sure you leave sufficient time to do so. 

In recent years many investors have found their money stranded in no-mans-land because the banks etc. have struggled to process new ISA applications made within the final week or so before the cut-off date, meaning that the investments can’t qualify for the tax-free status.
