Itemized Deductions
What is Itemized Deductions?
Itemized deductions are specific expenses allowed by the IRS that taxpayers can subtract from their adjusted gross income to reduce taxable income. Unlike the standard deduction, itemized deductions require detailed record-keeping and are only beneficial when they exceed the standard deduction amount. Common itemized deductions include mortgage interest, property taxes, charitable contributions, and medical expenses.
Why it matters
Itemized deductions can significantly lower your tax bill if your deductible expenses exceed the standard deduction. They provide tax relief for major life expenses like homeownership, healthcare, and charitable giving. Choosing between itemizing and taking the standard deduction can save you thousands in taxes, making it crucial to track and compare your options annually.
How it works
Taxpayers list eligible expenses on Schedule A of Form 1040. The IRS allows deductions for specific categories including home mortgage interest, state and local taxes (up to $10,000), charitable donations, medical expenses (over 7.5% of AGI), and casualty losses. The total itemized amount is compared to the standard deduction, and you choose the larger amount to subtract from AGI.
Examples
- A homeowner with $12,000 mortgage interest, $8,000 property taxes, and $5,000 charitable donations has $25,000 in itemized deductions, exceeding the $14,600 standard deduction for single filers.
- A taxpayer with $18,000 medical expenses (AGI is $150,000, so 7.5% threshold is $11,250) can deduct $6,750 after the threshold, plus $4,000 in charitable contributions for $10,750 total.
- A couple with $15,000 mortgage interest and $6,000 state taxes hits the $10,000 SALT limit, resulting in $21,000 itemized deductions vs. $29,200 standard deduction.
Common mistakes
- Not keeping adequate records and receipts
- Forgetting the medical expense threshold (7.5% of AGI)
- Exceeding SALT deduction limits without realizing it
- Double-counting expenses or charitable contributions
- Not comparing itemized total to standard deduction
- Claiming non-deductible expenses
