Men's assets as a basis for taxation (10)
I believe the answer is:
assessment
'for taxation' is the definition.
(thesaurus)
'men's assets as a basis' is the wordplay.
'men's assets' can be anagrammed to 'ASSESSMENT'.
However, I am not clear how the anagram is indicated.
Can you help me to learn more?
(Other definitions for assessment that I've seen before include "Opinion" , "Process of valuation" , "Review" , "Survey" , "amount to be paid" .)
