We did not save our over-the-counter medical receipts (aspirin, heat pads, advil etc.). Is there a number we or percent we can use for this cost?

[KathrynG3]

No. To include any value in your tax return, it must be defensible. See below for some suggestions in determining value without receipts. But, remember, that medical expenses must exceed 7.5% of your 2019 adjusted gross income to be deductible. For example, if you earned $10,000 for the year, 7/5% is $750. If you had $1,000 in deductible medical expenses, you would be allowed to deduction $250. ($1,000-$750=$250)

A best practice is to save the actual receipts. The next best approach would be to document the medical expenses being claimed by rebuilding a reasonable estimate. There is no need to attach this to your return, but do keep these records with your 2019 tax records. Likewise, the support does not have to take a tremendous amount of time.

For example, go through credit card statements and check actual costs. Or, use a spreadsheet to capture the expense that is reasonably valued including amounts for a predictable pattern for recurring purchases, An example for single purchases like the heating pad would be to include a screenshot of the item or one of comparable value in your records.

The IRS does not allow you to claim over the counter medical expenses.

MEDICAL EXPENSES

The medical expense deduction has to meet a rather large threshold before it can affect your return. The amount of medical (including dental, vision, etc.)  expenses that will count toward itemization is the amount that is OVER 7.5% of your adjusted gross income. You should only enter the amount that you paid in 2019—do not include any amounts that were covered by insurance or that are still outstanding. Of course, your medical expenses plus your other itemized deductions still have to exceed your standard deduction before you will see a difference in your tax due or refund.

To enter your medical expenses go to Federal>Deductions and Credits>Medical>Medical Expenses
