With the extended tax deadline, you’re likely searching for every possible write-off this tax season. And if you were healthy last year, you might be able to deduct extra expenses. Certain dental and medical-related procedures and programs are tax deductible—as long as their combined costs exceed 7.5% of your Annual Gross Income (AGI).

If you took charge of your health last year, here are 4 lesser-known deductions that might apply to you:

1. You took care of your teeth.

Preventive dental treatments such as cleanings, sealants, and fluoride are tax-deductible. Extensive eligible treatments include fillings, braces and dentures. Not surprisingly, teeth whitening is not included. Check the full list of potential write-offs.

2. You got your eyes examined.

Money spent on eye exams, eye glasses, contacts and eye surgery are all eligible for deductions.

3. You quit smoking.

If you participated in an IRS-approved program to stop smoking, you may be able to deduct the cost of your medical expenses. Patches, gum and other over-the-counter methods aren’t eligible.

4. You lost weight.

Weight loss programs may be tax-deductible as long as they’re related to a specific condition, such as hypertension or diagnosed obesity.

Remember, for your medical and dental deeds to meet the IRS’ expectations, your total dental and medical expenses must exceed 7.5% of your AGI.

If you have further questions, inquire with your tax consultant. If don’t have one on speed dial, many public libraries offer free tax prep help. Contact you local branch for more information.
