First remember ALL of your deductions (personal and business).
Remember your charitable deductions (you did give $100.00 of product to the cub scouts right?

).
Your medical deductions??? (co-pays, prescriptions, mileage, lodging, meals... the last three may not apply to you)
Your phone bill (or a portion there of), and any office expenses.
There are many more exemptions and deductions to be taken.
