Opportunity for tax rebate is a present help (4,3)

Ross

I believe the answer is:

gift aid

'opportunity for tax rebate' is the definition.
(charities can get a tax rebate with gift aid)

'present help' is the wordplay.
'present' becomes 'gift' (synonyms).
'help' becomes 'aid' (synonyms).
'gift'+'aid'='GIFT AID'

'is a' acts as a link.

I've seen this clue in The Guardian.
