What Is Schedule A?
Schedule A is a tax form used to report itemized deductions. It is an attachment to your Form 1040 that you use to file your annual income taxes and allows U.S. taxpayers to list specific expenses that the IRS considers deductible. Schedule A gives you the option to total up eligible expenses in categories like medical costs, mortgage interest, and charitable donations for your tax deductions.
Alternatively, the IRS allows you to choose the standard deduction, which is a flat amount determined by your filing status.
If your itemized deductions add up to more than the standard deduction, using Schedule A can lower your taxable income and potentially your tax liability.

How Schedule A Works
Schedule A is organized into several sections, each corresponding to a different type of deductible expense. These categories include:
- Medical and dental expenses (only the amount that exceeds 7.5% of your adjusted gross income)[1]
- State and local taxes paid, such as state income or property tax (up to $40,000 total)[2]
- Mortgage interest and points paid on your home loan
- Charitable contributions to qualified organizations
- Casualty and theft losses from federally declared disasters
- Other miscellaneous deductions (subject to certain limits)
Once you calculate and total your deductions across these sections, you compare that amount to the standard deduction for your filing status. If the total itemized deductions exceed the standard deduction, then it makes sense to file using Schedule A.
When to File a Schedule A?
Not everyone needs to file a Schedule A. In fact, most Americans take the standard deduction because it is easier and often more beneficial. However, Schedule A is worth considering if:
- You own a home and pay mortgage interest and property taxes
- You had significant medical expenses during the year
- You made large charitable donations
- You experienced a casualty loss in a federally declared disaster area
- You paid high state or local income taxes
For example, if you are a homeowner in a high-tax state like New York or California, itemizing could save you more money than taking the standard deduction. In 2025, the standard deduction is $15,000 for single filers and $30,000 for married couples filing jointly. If your eligible itemized deductions exceed those amounts, you may benefit from itemizing.
| Filing Status | 2025 Standard Deduction | 2026 Standard Deduction |
|---|---|---|
| Single | $15,750 | $16,100 |
| Married Filing Jointly | $31,500 | $32,200 |
| Married Filing Separately | $15,750 | $16,100 |
| Head of Household | $23,625 | $24,150 |
| Qualifying surviving spouse | $31,500 | $32,200 |

How to File a Schedule A
Filing Schedule A is not difficult, but it does require good recordkeeping. To prepare, you will need:
- Receipts for medical expenses, charitable donations, and major purchases
- Mortgage interest statements (Form 1098)
- Property tax and income tax statements
- Proof of casualty or theft losses, if applicable
Schedule A is included in most tax software programs, and it will prompt you to enter information in each deduction category. The best tax filing software programs will automatically determine whether itemizing or taking the standard deduction is more advantageous.
If you are filing by hand or with the help of a tax professional, you can download the form from the IRS website and complete it manually. You do not need to submit your receipts with your tax forms, but you need to retain proof in case you get audited or the IRS has questions about your filing in the future.
Pros of Filing a Schedule A
There are several advantages to filing a Schedule A:
- Potential for larger deductions - If your qualifying expenses exceed the standard deduction, itemizing can lower your taxable income.
- Customized deductions - Schedule A allows your tax return to reflect your actual financial situation rather than relying on a one-size-fits-all approach.
- Maximized tax benefits - Homeowners, charitable givers, and those with significant medical bills often benefit most from itemizing.
Filing Schedule A is also a good way to take advantage of deductions that many taxpayers overlook—such as medical miles driven for care or the fair market value of donated goods.

What Is Not Included on a Schedule A?
It is essential to know what does not belong on Schedule A. Some everyday expenses that are not deductible on this form include:
- Personal living expenses (like groceries or clothing)
- Childcare costs
- Commuting costs to and from work
- Most unreimbursed work-related expenses
- Federal income taxes
- Homeowner’s association (HOA) fees
Just because you spend money on something does not mean it is deductible. Only expenses explicitly allowed by the IRS, and listed in the Schedule A categories, can be claimed.

Smart Summary
Schedule A is the IRS form used for itemized deductions. If your eligible expenses add up to more than the standard deduction, then filing a Schedule A can help you save money on your taxes. For most taxpayers, the standard deduction is the simpler and better choice to save on their taxes. But if you had a financially eventful year, it may be worth exploring if itemizing your deductions works in your favor.
