Toll, tax (4)
I believe the answer is:
levy
This clue is a double definition.
'toll' is the first definition.
(I've seen this before)
'tax' is the second definition.
(I've seen this in another clue)
(Other definitions for levy that I've seen before include "enlisted troops" , "Financial charge" , "Raise - army (or money for it)" , "Tax, fee, fine, etc" , "Charge imposed and collected" .)
