No. The IRS does not allow this. If you paid for Invisalign using pre-tax dollars, you have already received a tax benefit. You cannot claim those same dollars as an itemized deduction.
Invisalign is a tax-deductible medical expense used to treat functional dental issues like malocclusion, crowding, and bite misalignment. Under the IRS publication 502, McKinney patients can claim unreimbursed orthodontic costs as an itemized deduction on Schedule A, provided their total medical expenses exceed 7.5% of their income. At Enamel Dentistry McKinney, we believe that a healthy smile should be easy on your wallet.
According to a publication by the IRS, medical and dental expenses are deductible if they are to prevent or alleviate dental disease (IRS, 2018). This includes structural changes such as Invisalign. While purely cosmetic whitening is usually excluded, Invisalign is almost always used to correct crowding, spacing, or bite issues. In McKinney, we often see patients whose bite alignment causes traumatic occlusion. This means that the teeth are coming into contact with each other with too much force, causing wear. Because these issues lead to gum disease and tooth loss if ignored, the IRS views the correction as a medical necessity. This means that the aligners, X-rays, and even the final retainers are all part of the deductible medical pool.
To claim Invisalign on your taxes, you must itemize your deductions on Form 1040. The IRS states that you can deduct part of your total unreimbursed medical expenses that is more than 7.5% of your adjusted gross income (IRS, n.d.). For example, if your adjusted gross income is $100,000, the first $7,500 of your medical bills are not deductible. However, if your Invisalign treatment costs $5,500 and you had another $4,000 in medical bills, you would have $9,500 in total medical expenses. In this scenario, you could deduct $2,000 from your taxable income. This is why many patients in McKinney choose to start treatment in the same year that they have other major medical procedures to clear the 7.5% threshold.
The IRS is quite strict about the difference between cosmetic and medical care. To protect yourself in the event of an audit, you will need more than a receipt. At Enamel Dentistry McKinney, we provide our patients with a letter of medical necessity. The FSA governing store supports that a letter of medical necessity is needed to receive reimbursement (FSA Store, 2026). This document outlines the clinical reasons for treatment. We may cite issues such as crowding-induced periodontitis or malocclusion leading to jaw dysfunction. By documenting that the treatment is preventing bone loss in the future, this helps your CPA to categorize the expense correctly. This clinical oversight is the difference between a claim being accepted or rejected.
