Wager’s banked after tax for woman (7)
I believe the answer is:
'woman' is the definition.
'wager's banked after tax' is the wordplay.
'wager' becomes 'ante' (ante can mean a stake for a bet or wager).
'banked' means one lot of letters goes inside another (inserted letters get stored or banked).
'after tax' becomes 'net' (I've seen this before).
'ante' going around 'net' is 'ANNETTE'.
'for' is the link.
(Other definitions for annette that I've seen before include "Name; teen tan (anag.)" , "Girl's name" , "- - Crosbie (TV)" , "girl" , "Female" .)
