Former partners loaded with tax for such indulgences (8)
I believe the answer is:
excesses
'indulgences' is the definition.
(excess is a kind of indulgence)
'former partners loaded with tax' is the wordplay.
'former partners' becomes 'exes' (ex-lovers).
'loaded with' is an insertion indicator.
'tax' becomes 'cess' (I've seen this before).
'exes' going around 'cess' is 'EXCESSES'.
'for such' acts as a link.
(Other definitions for excesses that I've seen before include "Outrageous acts" , "they're sometimes included in insurance policies" , "Floods" .)
