A refund from the government, after you submit this? (3,6)
I believe the answer is:
tax return
'government after you submit this?' is the definition.
The definition suggests a singular noun which matches the answer.
'a refund from the' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
'refund' could be 'return' (synonyms) and 'return' is found within the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is located in the answer.
A single letter 'x' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tax return that I've seen before include "Citizen's annual responsibility" , "financial statement" .)
