Name the woman taking the tax people in (7)

'name the woman' is the definition.
'Mirabel' can be an answer for 'name'. I am unsure of the 'the woman' bit.

'taking the tax people in' is the wordplay.
'taking' becomes 'mabel' (I can't justify this - if you can you should give a lot more credence to this answer).
'the tax people' becomes 'IR' (abbreviation for Inland Revenue).
'in' indicates putting letters inside.
'mabel' enclosing 'ir' is 'MIRABEL'.

Can you help me to learn more?
