What Is Schedule A (Form 1040)?

Schedule A is an attachment to Form 1040, used to itemize your deductions rather than take the standard deduction. By listing qualified expenses like medical costs, mortgage interest, charitable donations, and state/local taxes, you may be able to lower your taxable income and pay less to the IRS.

Without Schedule A, most taxpayers simply claim the standard deduction, a fixed amount based on filing status. But for those with higher deductible expenses, Schedule A can yield bigger tax savings.

Who Should File Schedule A?

You should consider filing Schedule A if your itemized deductions exceed the standard deduction for your filing status:

2024 standard deduction amounts:

• $14,600 – Single

• $29,200 – Married Filing Jointly

• $21,900 – Head of Household

You’re likely a good candidate for Schedule A if you:

✅ Paid significant state and local taxes
✅ Paid mortgage interest on your home
✅ Had high medical or dental expenses
✅ Made large charitable contributions
✅ Incurred casualty or theft losses in a federal disaster area

What Can You Deduct on Schedule A?

Schedule A allows you to deduct eligible personal expenses in these categories:

1. Medical and Dental Expenses

   • Only the amount exceeding 7.5% of your adjusted gross income (AGI) is deductible

   • Includes doctor visits, prescriptions, surgeries, and medical equipment

2. State and Local Taxes Paid (SALT)

   • Deduct up to $10,000 ($5,000 if married filing separately)

   • Includes property taxes, income taxes, and sales tax

3. Home Mortgage Interest

   • Interest on mortgages up to $750,000 (or $1M for older loans)

   • Includes points and mortgage insurance premiums (with limits)

4. Charitable Contributions

   • Cash and non-cash donations to qualified nonprofits

   • Keep proper records and receipts

5. Casualty and Theft Losses

   • Only for losses in federally declared disaster areas

   • Must exceed 10% of AGI after subtracting $100 per event

6. Other Miscellaneous Deductions (limited)

   • Gambling losses (up to amount of winnings)

   • Impairment-related work expenses for the disabled

When to Use Standard Deduction vs. Itemizing

Use Schedule A if your total itemized deductions exceed the standard deduction. Otherwise, stick with the standard deduction—it’s simpler and often more beneficial for most filers.

Common Mistakes to Avoid

❌ Not keeping proper receipts for charitable donations
