I believe the answer is:

taxable

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

'to burden the fit fiscally' is the definition.
I can't tell whether this defines the answer.

'to burden the fit' is the wordplay.
'to burden' becomes 'tax' (I've seen this before).
'the fit' becomes 'able' (I've seen this before).
'tax'+'able'='TAXABLE'

Can you help me to learn more?

(Another definition for taxable that I've seen is " Subject to levy".)

I've seen this clue in the Evening Standard.
