Holy see tax I preserve (7)

I believe the answer is:

vatican

'holy see' is the definition.
(I've seen this before)

'tax i preserve' is the wordplay.
'tax' becomes 'VAT' (UK Value Added Tax).
'preserve' becomes 'can' (canning is a kind of preserving).
'vat'+'i'+'can'='VATICAN'

(Other definitions for vatican that I've seen before include "Papal residence" , "Papal palace" , "City within Rome" , "Papal authority" , "Pope's home" .)

I've seen this clue in The Telegraph.
