OTC tax refund is money the IRS sends back because you overpaid taxes on over-the-counter medicines and medical supplies
An OTC tax refund is a refund from the Internal Revenue Service (IRS) for taxes you paid on over-the-counter medicines and certain medical supplies. The IRS allows you to deduct these costs from your taxable income under specific conditions, and if you paid more in taxes than you owed, you get money back.
This is different from a general tax refund. A general refund means you had too much money withheld from your paychecks or made estimated tax payments that were too high. An OTC refund specifically recognizes that you spent money on medical items that the tax code treats as deductible medical expenses.
The catch: you can only claim OTC medicines and supplies if you itemize your deductions on your tax return. Most people use the standard deduction instead, which means they cannot claim OTC costs. If you do itemize and your total medical expenses (including OTC items) exceed a certain percentage of your income, you can deduct the amount above that threshold.
Key Takeaways
- OTC medicines and supplies are only deductible if you itemize deductions on your tax return, not if you take the standard deduction.
- You must keep receipts for all OTC purchases you want to claim, including the date, amount, and what the item was.
- Your total medical expenses (including OTC items, doctor visits, prescriptions, and insurance premiums) must exceed 7.5% of your adjusted gross income before you can deduct any of them.
- The IRS considers insulin, pain relievers, cold medicine, allergy medicine, and antacids deductible, but not vitamins or supplements unless prescribed by a doctor.
Which OTC items count as deductible medical expenses
The IRS has a specific list of over-the-counter medicines and supplies that count. Common ones include insulin, pain relievers like ibuprofen and acetaminophen, cold and flu medicines, allergy medicines, antacids, and first-aid supplies like bandages and antiseptic ointment.
Items that do not count include vitamins, minerals, and supplements — unless a doctor prescribed them specifically for you in writing. Toothpaste, deodorant, shampoo, and other personal hygiene items also do not count, even if they are over-the-counter.
Medical equipment and devices can count if they treat a specific condition. Examples include blood pressure monitors, glucose meters, heating pads, crutches, and wheelchairs. The item must be primarily medical in nature, not something used for general wellness.
How the medical expense deduction actually works
To claim an OTC refund, you first add up all your medical expenses for the year — prescriptions, doctor visits, hospital bills, insurance premiums, dental work, glasses, hearing aids, and OTC items. Then you subtract 7.5% of your adjusted gross income (AGI) from that total. Only the amount above that threshold is deductible.
For example, if your AGI is $50,000, the threshold is $3,750. If your total medical expenses are $5,000, you can deduct $1,250 ($5,000 minus $3,750). That deduction reduces your taxable income, which lowers the tax you owe or increases your refund.
This is why most people do not claim OTC costs: the 7.5% threshold is high. You need significant medical expenses in a single year to benefit. If your medical costs are spread across years or are modest, you may not reach the threshold at all.
When itemizing makes sense versus taking the standard deduction
You can only deduct medical expenses if you itemize deductions on Schedule A of your tax return. The standard deduction is a flat amount the IRS lets you subtract from your income without listing anything — for 2024, it is $14,600 for single filers and $29,200 for married couples filing jointly. These amounts change each year.
If your total itemized deductions (medical expenses plus mortgage interest, state taxes, charitable donations, and other deductible items) exceed the standard deduction, itemizing saves you money. If they do not, you are better off taking the standard deduction.
Many people with modest medical expenses should not itemize. You would need both high medical costs and other deductible expenses to make itemizing worthwhile. A tax professional can help you calculate which approach saves you more money in your specific situation.
What records you need to keep
The IRS does not require you to send receipts with your tax return, but you must keep them for your records in case of an audit. For each OTC purchase, save the receipt showing the date, the amount paid, and what the item was.
If you bought items at a pharmacy or drugstore, the receipt usually lists the product name. If you are unsure whether something counts, write a note on the receipt or keep a separate list. This makes it much easier to add everything up at tax time and to defend your deduction if the IRS asks.
Keep receipts for at least three years. The IRS can audit returns from the past three years, and in some cases up to six years if they suspect underreporting of income.
How to report OTC expenses on your tax return
You report medical expenses on Schedule A (Form 1040), which is the form you use to itemize deductions. Line 1 of Schedule A is where you enter your total medical and dental expenses for the year.
You do not list each individual OTC item. Instead, you add them all together — OTC medicines, OTC supplies, prescriptions, doctor bills, hospital bills, insurance premiums, dental work, vision care, and anything else medical — and enter one total number.
Then the form automatically subtracts 7.5% of your AGI. The result is your deductible medical expense amount. If that number is zero or negative, you cannot deduct any medical expenses that year.
Common reasons people do not get an OTC tax refund
The most common reason is that people take the standard deduction instead of itemizing. If you do not itemize, OTC costs do not reduce your taxes at all, and you get no refund for them.
The second reason is that medical expenses do not reach the 7.5% threshold. If your income is $60,000 and your total medical expenses are $3,000, the threshold is $4,500. You cannot deduct anything because your expenses are below the threshold.
A third reason is that people do not keep receipts or do not realize OTC items count. If you throw away receipts or do not track purchases, you cannot claim them. The IRS will not take your word for it without documentation.
Frequently Asked Questions
Can I claim OTC medicines I bought last year on this year's tax return?
No. You report medical expenses in the year you paid for them. If you bought ibuprofen in December 2023, you claim it on your 2023 return. Expenses from different years cannot be combined to reach the 7.5% threshold.
Does my spouse's medical expenses count if we file jointly?
Yes. If you file a joint return, you combine both spouses' medical expenses and use the joint AGI to calculate the 7.5% threshold. This sometimes helps couples reach the threshold when one spouse has high medical costs.
What if I have a Health Savings Account or Flexible Spending Account?
If you paid for OTC items with money from an HSA or FSA, you cannot also deduct them on your tax return. You are using pre-tax money to buy them, so you get the tax benefit through the account, not through itemization. Keep receipts to prove the items were paid from the account.
Are prescription drugs treated differently than OTC medicines?
No. Both prescription and OTC medicines are treated the same way for tax purposes. Both count as medical expenses, both require receipts, and both are subject to the 7.5% threshold. The difference is that prescriptions are usually more expensive, so they are easier to track.
If I get a refund, does that mean I overpaid my taxes?
Not necessarily. A refund means the total tax you paid (through withholding or estimated payments) was more than the tax you actually owed after all deductions and credits. The OTC deduction reduces your taxable income, which can lower your tax bill and result in a refund, but the refund comes from overpayment overall, not from the OTC items themselves.
