9. Understanding Medical Expenses and Deductions

Navigating the healthcare system often involves understanding medical expenses, especially when it comes to taxes. Let’s explore what medical expenses are, what you can include, and how to potentially deduct them.

9.1. What Qualifies as a Medical Expense?

Medical expenses are defined as the costs of diagnosis, cure, mitigation, treatment, or prevention of disease. They also include expenses for affecting any part or function of the body. These expenses cover payments for legal medical services rendered by physicians, surgeons, dentists, and other medical practitioners. The costs of equipment, supplies, and diagnostic devices needed for these purposes are also included.

Key Points:

• Medical care expenses must primarily alleviate or prevent a physical or mental disability or illness.
• Expenses that are merely beneficial to general health, such as vitamins or a vacation, are not included.
• Premiums paid for insurance covering medical care expenses and transportation costs to receive medical care are includible.
• Amounts paid for qualified long-term care services and qualified long-term care insurance contracts may also be included.

9.2. Expenses You Can Include This Year

You can include only the medical and dental expenses you paid this year. Generally, payments for medical or dental care you will receive in a future year are excluded. However, there are exceptions, such as in the case of a decedent.

Payment Methods:

• If you pay medical expenses by check, the day you mail or deliver the check is generally the date of payment.
• For “pay-by-phone” or “online” accounts, the date reported on the statement of the financial institution is the date of payment.
• If you use a credit card, include medical expenses in the year the charge is made, not when you actually pay the amount charged.

Amending Prior Returns:

If you did not claim a medical or dental expense that would have been deductible in an earlier year, you can file Form 1040-X, Amended U.S. Individual Income Tax Return, to claim a refund.

9.3. What Medical Expenses Can Be Deducted?

Generally, you can deduct on Schedule A (Form 1040) only the amount of your medical and dental expenses that is more than 7.5% of your Adjusted Gross Income (AGI).

Example:

If your AGI is $60,000, 7.5% of your AGI is $4,500. If your medical expenses total $7,000, you can deduct $2,500 ($7,000 – $4,500).

9.4. Whose Medical Expenses Can You Include?

You can include medical expenses you pay for yourself, as well as those you pay for someone who was your spouse or your dependent either when the services were provided or when you paid for them. Different rules apply for decedents and individuals under multiple support agreements.

Spouse:

You can include medical expenses you paid for your spouse if you were married either at the time your spouse received the medical services or when you paid the medical expenses.

Dependent:

You can include medical expenses you paid for your dependent if the person was your dependent either at the time the medical services were provided or at the time you paid the expenses.
