Coming out badly in tax claim is let-down
I believe the answer is:
anticlimax
'let-down' is the definition.
(I've seen this before)
'coming out badly in tax claim' is the wordplay.
'in tax claim' can be anagrammed to 'ANTICLIMAX'.
Though, I'm not sure how this is indicated.
'is' is the link.
Can you help me to learn more?
(Other definitions for anticlimax that I've seen before include "Disappointing result" , "Damp squib" , "Come-down" , "Disappointing ending" , "disappointing outcome" .)
