An itemized deduction is a specific expense that taxpayers can list separately on their tax returns to reduce their taxable income. Unlike the standard deduction, which is a fixed amount that taxpayers can deduct, itemized deductions allow for a reduction in taxable income based on particular, eligible expenses. These deductions are recorded on Schedule A of Form 1040.
Types of Itemized Deductions
Medical and Dental Expenses
Taxpayers can deduct medical and dental expenses that exceed a certain percentage of their Adjusted Gross Income (AGI). These can include costs for prescription medications, hospital stays, and health insurance.
State and Local Taxes (SALT)
This includes deductions for state and local income, sales, or property taxes. However, there is a cap on the SALT deduction, currently set at $10,000.
Mortgage Interest
Interest on home mortgage debt can be deducted, up to a certain limit. This deduction is an incentive for homeownership.
Charitable Contributions
Donations to qualified charitable organizations can be deducted. These contributions must be documented and meet specific IRS criteria.
Casualty and Theft Losses
Losses incurred from federally-declared disasters can be deducted. These deductions are subject to specific criteria and thresholds.
Miscellaneous Deductions
These include job-related expenses, investment expenses, and other deductions that exceed 2% of AGI. However, many miscellaneous deductions have been suspended under the Tax Cuts and Jobs Act (TCJA) for tax years 2018 through 2025.
Special Considerations
Thresholds and Limits
Certain itemized deductions are only available if they exceed a specific percentage of the taxpayer’s income. For example, medical expenses must exceed 7.5% of AGI to be deductible.
Alternative Minimum Tax (AMT)
Some itemized deductions are not allowed when calculating the AMT. Taxpayers subject to the AMT may find it advantageous to take the standard deduction instead.
Documentation
Detailed records are essential for itemized deductions. Receipts, invoices, and other documentation must be maintained to substantiate each deduction.
Example
Consider a taxpayer with the following expenses:
- Medical expenses: $10,000 (with an AGI of $50,000)
- State income tax: $4,000
- Property tax: $3,000
- Mortgage interest: $5,000
- Charitable contributions: $1,000
Assuming the medical expense threshold is 7.5% of AGI:
Deductible medical expenses = $10,000 - (7.5% of $50,000) = $10,000 - $3,750 = $6,250
Total itemized deductions = $6,250 (medical) + $4,000 (state income tax) + $3,000 (property tax) + $5,000 (mortgage interest) + $1,000 (charitable) = $19,250
Historical Context
The concept of itemized deductions has been part of the U.S. tax system for many decades. It aims to provide tax relief for significant, necessary expenses, and to encourage certain behaviors, like charitable giving and homeownership. The Tax Cuts and Jobs Act of 2017 made substantial changes to the availability and limits of itemized deductions, affecting a wide range of taxpayers.
Applicability
Itemized deductions can significantly reduce taxable income for individuals with considerable deductible expenses. However, the choice between itemizing and taking the standard deduction should be made carefully, considering the specific financial situation and tax implications.
Comparisons
Itemized Deduction vs. Standard Deduction
The standard deduction is a flat amount set by the IRS, varying by filing status:
- Single: $12,550
- Married filing jointly: $25,100
- Head of household: $18,800
Taxpayers must choose between using the standard deduction or itemizing deductions based on which option provides a greater tax benefit.

Summary
Itemized deductions offer a means for taxpayers to reduce their taxable income based on specific eligible expenses. By listing these deductions separately on their tax returns, taxpayers might find greater tax benefits compared to the standard deduction. However, itemizing requires diligent record-keeping and an understanding of applicable thresholds and limits.
