End the French tax levied by French king! (6)

I believe the answer is:

taille

'tax levied by french king' is the definition.
(historical tax in France)

'end the french' is the wordplay.
'end' becomes 'tail' (tail is a kind of end).
'the french' becomes 'le' ('the' in French).
'tail'+'le'='TAILLE'

(Another definition for taille that I've seen is " Tax levied on French".)

I've seen this clue in The Guardian.
