Criminally dump 'income' for collection (10)
I believe the answer is:
compendium
'collection' is the definition.
(synonyms)
'criminally dump income' is the wordplay.
'criminally' indicates anagramming the letters.
'dump'+'income'='dumpincome'
'dumpincome' anagrammed gives 'COMPENDIUM'.
'for' acts as a link.
(Other definitions for compendium that I've seen before include "Box containing many games" , "Digest - anthology" , "Collection of similar items" , "Box of games; handbook" .)
