Corbynistas to tax loaf and ginger nuts (8)

I believe the answer is:

redheads

I'm a little stuck... Click here to teach me more about this clue!

'corbynistas to tax' is the definition.
I can't judge whether this defines the answer.

'loaf and ginger nuts' is the wordplay.
'loaf' becomes 'head' (slang term).
'and' is a charade indicator (letters next to each other).
'ginger' becomes 'red ginger' (red hair).
'nuts' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'head' put after 'red' is 'redhead'.
'redhead'+'s'='REDHEADS'

Can you help me to learn more?

(Other definitions for redheads that I've seen before include "ducks" , "ginger group" .)
