'taxing period' is the definition.
'fiscal year' can be an answer for 'period' (fiscal year is a kind of period). I'm not sure about the 'taxing' bit.

'a scary life at sea' is the wordplay.
'at sea' indicates anagramming the letters.
'a'+'scary'+'life'='ascarylife'
'ascarylife' with letters rearranged gives 'FISCAL YEAR'.

'from' is the link.
