Charge of cab not going all the way (3)
I believe the answer is:
tax
'charge' is the definition.
(I know that tax is a type of levy)
'cab not going all the way' is the wordplay.
'cab' becomes 'taxi' (taxi cab).
'not going all the way' means to remove the last letter.
'taxi' with its last letter taken off is 'TAX'.
'of' acts as a link.
(Other definitions for tax that I've seen before include "Overburden with levy?" , "Strain; levy" , "Tariff" , "Levy for public purposes" , "Impost" .)
