Taxes have to end (3)
I believe the answer is:
axe
'end' is the definition.
(axing is a kind of ending)
'taxes have' is the wordplay.
'have' says the answer is hidden in the clue.
'AXE' is hidden within 'taxes'.
'to' is the link.
(Other definitions for axe that I've seen before include "Eliminate" , "fell" , "Chop" , "Means of cutting" , "flower in Devon" .)
