5) Points on Refinancing With interest rates remaining so low over the past few years, lots of homes have been refinanced, sometimes more than once. Any points you pay to refinance your home can be deducted on a monthly basis over the life of the new loan.
6) Any health insurance premiums you pay, including some long-term-care premiums based on your age and Medicare premiums you pay, are potentially deductible. But you have to add these to your medical expense pot. Medical expenses have to exceed 7.5% (as of 2011) of your adjusted gross income before they give you any tax benefit.
7) If you're a teacher and each year you're buying kleenex and crayons and computer equipment with your own money, you can deduct up to $250 per year as of 2011.
8) Business related parking and tolls, and business related mileage ($0.51 per mile as of 2011). You can't double dip if your employer is reimbursing your mileage though.
