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:
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
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
Home Mortgage Interest
Interest on mortgages up to $750,000 (or $1M for older loans)
Includes points and mortgage insurance premiums (with limits)
Charitable Contributions
Cash and non-cash donations to qualified nonprofits
Keep proper records and receipts
Casualty and Theft Losses
Only for losses in federally declared disaster areas
Must exceed 10% of AGI after subtracting $100 per event
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.
TAXtical can compare both options to ensure you get the largest tax benefit.

❌ Not keeping proper receipts for charitable donations
