2015 Tax Tip: Most Commonly-Overlooked Deductions

Home office expenses and some costly medical procedures can be deducted.

— -- In the midst of preparing taxes, there are many common things people forget they can claim as deductions.

One of the biggest deductions people overlook is the home office deduction, according to Tom Wheelwright with the CPA firm ProVision.

"You may have an office in your home that is strictly for what you do in your investing. There's a lot of deductions available there,” says Wheelwright.

Deductions can include an air conditioning bill, heating bill and even a water bill, according to Wheelwright.

“You even get to depreciate a part of your house,” Wheelwright says.

If you're drowning in student debt, you can also deduct your loan interest. Tax experts say that’s often overlooked by people who don't itemize their returns.

There’s also never been a better time to kick the habit. Smoking cessation programs and patches can be deducted.
