Income concerning chosen location (7)
I believe the answer is:
revenue
'income' is the definition.
(I know that revenue is a type of government income)
'concerning chosen location' is the wordplay.
'concerning' becomes 're' (both can mean on a particular topic).
'chosen location' becomes 'venue' (I've seen this before).
're'+'venue'='REVENUE'
(Other definitions for revenue that I've seen before include "Gross business income" , "profit" , "Takings" , "Income from tax" , "Money coming in" .)
