What Are Itemized Deductions?

Itemized deductions are specific expenses you can subtract from your adjusted gross income (AGI) to lower your taxable income. Reported on Schedule A with Form 1040, they’re an alternative to the standard deduction. You choose to itemize if your total deductions exceed the standard deduction, saving you more on taxes. Part of the U.S. tax code, itemized deductions encourage spending on things like homeownership, charity, or healthcare.

Common Itemized Deductions

  • Medical Expenses: Costs exceeding 7.5% of your AGI.

  • State and Local Taxes (SALT): Up to $10,000 for property, income, or sales taxes.

  • Mortgage Interest: Interest on home loans up to $750,000.

  • Charitable Donations: Cash or property given to qualified organizations.

  • Casualty and Theft Losses: Losses from federally declared disasters.

  • Other Deductions: Gambling losses or unreimbursed employee expenses (limited).

Why Choose Itemized Deductions?

Itemized deductions offer big benefits if your expenses are high:

1. Bigger Tax Savings

If your deductions exceed the standard deduction ($15,000 single, $30,000 married filing jointly in 2025), itemizing lowers your taxable income more.

2. Tailored to Your Spending

Itemized deductions reward expenses like homeownership, medical care, or charity, fitting your lifestyle.

3. Flexibility

Combine with other tax breaks, like the Qualified Business Income (QBI) Deduction or retirement contributions.

4. Maximizes Refunds

Itemizing often leads to larger tax refunds for high earners or homeowners.

A Real-Life Story: How Lisa Saved with Itemized Deductions

Lisa, a 40-year-old teacher, thought the standard deduction was her only option. After buying a home, she learned about itemized deductions from a friend. Using TurboTax, Lisa listed $18,000 in expenses: $10,000 in mortgage interest, $5,000 in state taxes, and $3,000 in charitable donations. This beat the $15,000 standard deduction, saving her $1,200 in taxes. “Itemized deductions turned my home into a tax break,” Lisa says. Her story shows how itemizing can boost your refund.

Understanding the Tax Implications of Itemized Deductions

The tax implications of itemized deductions are key to maximizing savings, but there are rules to know.

1. Medical Expenses

Deduct medical expenses exceeding 7.5% of your AGI. Examples:

  • Doctor visits, prescriptions, or surgeries.

  • Dental care or eyeglasses.

  • Health insurance premiums (if self-employed).

For example, if your AGI is $50,000, deduct expenses over $3,750. Report on Schedule A, Line 1.

2. State and Local Taxes (SALT)

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

  • State income taxes or sales taxes (choose one).

  • Property taxes on your home or car.

Report on Schedule A, Line 5. The $10,000 cap, set by the Tax Cuts and Jobs Act, limits high earners.

3. Mortgage Interest

Deduct mortgage interest on loans up to $750,000 ($375,000 if married filing separately) for your primary or second home. Includes:

  • Interest on home mortgages.

  • Home equity loan interest (if used for home improvements).

Report on Schedule A, Line 8, with Form 1098.

4. Charitable Donations

Deduct charitable donations to qualified organizations, like:

  • Cash or checks.

  • Property (e.g., clothes, cars).

  • Volunteer expenses (e.g., mileage at 14 cents/mile).

Limits apply: 20%–60% of AGI, depending on the donation type. Report on Schedule A, Line 11, with Form 8283 for non-cash donations over $500.

5. Casualty and Theft Losses

Deduct casualty and theft losses from federally declared disasters, like hurricanes. Calculate:

  • Loss amount minus insurance reimbursements.

  • Subtract $100 per event and 10% of AGI.

Report on Schedule A, Line 15, with Form 4684.

6. Other Itemized Deductions

Limited deductions include:

  • Gambling losses: Up to gambling winnings.

  • Unreimbursed employee expenses (rare post-2017).

Report on Schedule A, Line 16.

7. Alternative Minimum Tax (AMT)

Some itemized deductions, like state taxes, are disallowed under the AMT, affecting high earners. Check with Form 6251.

For more, see IRS Publication 529.

Risks of Itemized Deductions

While itemized deductions can save money, there are pitfalls:

1. Deduction Limits

Caps like $10,000 for SALT or 7.5% of AGI for medical expenses limit savings.

2. Audit Risk

Large deductions, like high charitable donations, may trigger an IRS audit. Keep receipts.

3. Complexity

Itemizing requires detailed records and forms, unlike the standard deduction.

4. Phase-Outs

High earners may lose deductions under AMT or Pease limitations (if reinstated).

Another Anecdote: How Mike Maximized Itemized Deductions

He used H&R Block to itemize $22,000 in deductions: $10,000 in SALT, $8,000 in medical expenses, and $4,000 in charitable donations. This beat the $15,000 standard deduction, saving him $1,800. “Itemized deductions made my taxes manageable,” Mike says. His story proves itemizing can be a lifesaver.
