It's mid-April, the wrong time to send money! (5)
I believe the answer is:
remit
'send money' is the definition.
(I've seen this in another clue)
'it's mid-april the wrong time' is the wordplay.
'it's mid' says to take the centre (mid- can mean the middle of something).
'the wrong' indicates an anagram.
The central letter of 'april' is 'r'.
'time' anagrammed gives 'emit'.
'r'+'emit'='REMIT'
'to' acts as a link.
(Other definitions for remit that I've seen before include "Scope of prescribed job" , "Maybe suspend" , "Brief - transfer" , "Dispatch" , "Send (money) in payment; pardon" .)
