Taxes get dismissal (3)
I believe the answer is:
axe
'dismissal' is the definition.
'taxes get' is the wordplay.
'get' indicates the answer is hidden within the clue (I've seen 'gets' mean this).
'AXE' is hidden within 'taxes'.
(Other definitions for axe that I've seen before include "cancellation" , "Cut (jobs)" , "flower in Devon" , "US jazz instrument" , "Abandon project or cut back on resources" .)
