County that’s not so forthcoming to auditors (5)

I believe the answer is:

shire

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

'county' is the definition.
(term for a county, eg Hampshire, Warwickshire etc)

I don't understand the remainder of the clue.

Can you help me to learn more?

(Other definitions for shire that I've seen before include "County (esp. in England)" , "Breed of draught horse" , "Devon maybe" , "The -----: Tolkien's hobbit-land" , "Berks" .)

I've seen this clue in The Times.
