Medical expenses can lower taxes. It is important to keep good records and know what to deduct. Here are some tips to know what qualifies as medical and dental expenses:

• Itemize. Taxpayers can only claim medical expenses that they paid for in 2016 if they itemize deductions on a federal tax return.
• Qualifying Expenses. Taxpayers can include most medical and dental costs that they paid for themselves, spouses and dependents including:

• • The costs of diagnosing, treating, easing or preventing disease.
  • The costs paid for prescription drugs and insulin.
  • The costs paid for insurance premiums for policies that cover medical care.
  • Some long-term care insurance costs.

Exceptions and special rules apply. Costs reimbursed by insurance or other sources normally do not qualify for a deduction.

• Travel Costs Count. It is possible to deduct travel costs paid for medical care. This includes costs such as public transportation, ambulance service, tolls and parking fees. For use of a car, deduct either the actual costs or the standard mileage rate for medical travel. The rate is 19 cents per mile for 2016.
• No Double Benefit. Don’t claim a tax deduction for medical expenses paid with funds from your Health Savings Account or Flexible Spending. Amounts paid with funds from these plans are usually tax-free.
