Acho que você precisa:
WHERE (`DATE` between DATE_FORMAT(NOW() ,'%Y-01-01') AND NOW() )
Para ser honesto, você poderia fazer:
WHERE (`DATE` between DATE_FORMAT(NOW() ,'%Y') AND NOW() )
WHERE (`DATE` between DATE_FORMAT(NOW() ,'%Y-01-01') AND NOW() )
WHERE (`DATE` between DATE_FORMAT(NOW() ,'%Y') AND NOW() )
