Rush to pocket daily tax (9)
I believe the answer is:
surcharge
'tax' is the definition.
(I've seen this before)
'rush to pocket daily' is the wordplay.
'rush' becomes 'surge' ('surge' can be a synonym of 'rush').
'to pocket' means one lot of letters goes inside another.
'daily' becomes 'char' (I've seen this before).
'surge' going around 'char' is 'SURCHARGE'.
(Other definitions for surcharge that I've seen before include "extra amount" , "Addition to usual payment" , "More to pay" , "Additional sum demanded" , "Extra payment" .)
