Tax making wonderful profits (7,5)
I believe the answer is:
capital gains
'tax making wonderful profits' is the definition.
I can't tell whether this defines the answer.
'wonderful profits' is the wordplay.
'wonderful' becomes 'capital'.
'profits' becomes 'gains' ('gain' can be a synonym of 'profit').
'capital'+'gains'='CAPITAL GAINS'
Can you help me to learn more?
(Other definitions for capital gains that I've seen before include "target of 17, 8 [CHANCELLORS STATEMENT] - with 6a" , "Profits from investment sales" , "Profits from the sale of assets" , "post-war Honolulu and Juneau for US?" , "Profit" .)
