Every year, you choose between two ways to reduce your taxable income: take the standard deduction or itemize your deductions on Schedule A. Most people default to standard — but that decision could be costing you money.
What Is the Standard Deduction?
The standard deduction is a flat amount that reduces your taxable income without requiring documentation. For 2024, the amounts are:
| Filing Status | Standard Deduction | |---|---| | Single | $14,600 | | Married Filing Jointly | $29,200 | | Head of Household | $21,900 | | Single, age 65+ | $16,550 | | MFJ, both age 65+ | $32,300 |
You claim it automatically — no receipts, no forms, no tracking needed.
What Does Itemizing Mean?
Itemizing means listing your actual deductible expenses on Schedule A. Common itemized deductions include:
- Mortgage interest (Form 1098 from your lender)
- State and local taxes (SALT) — capped at $10,000 for income, sales, and property taxes combined
- Charitable contributions — cash and non-cash donations to qualifying organizations
- Medical expenses — only the amount exceeding 7.5% of your adjusted gross income
- Casualty and theft losses — limited to federally declared disaster areas
When Does Itemizing Beat the Standard Deduction?
You should itemize when your total qualifying deductions exceed your standard deduction amount. This commonly happens when you:
- Own a home with a mortgage — mortgage interest alone can push you over the threshold
- Pay high property taxes in addition to state income taxes
- Made large charitable donations during the year
- Had significant medical expenses — especially if you were uninsured or had a major procedure
- Live in a high-tax state like California, New York, or New Jersey
The $10,000 SALT Cap Changes the Math
Before 2018, you could deduct unlimited state and local taxes. Now the cap is $10,000. This significantly reduced the benefit of itemizing for many homeowners in high-tax states — because even if property taxes alone exceed $10,000, you can't deduct the excess.
A Simple Test
Add up your estimated itemized deductions:
- Mortgage interest (from your year-end statement)
- Property taxes (up to the $10,000 SALT cap combined with state income taxes)
- Charitable contributions
- Medical expenses above 7.5% of your AGI
If the total exceeds your standard deduction, itemizing wins. If not, take the standard deduction and move on.
You Can't Do Both
It's one or the other — you cannot claim both the standard deduction and itemized deductions on the same return.
What About Bunching?
If your itemized deductions are close to the standard deduction in a given year, consider bunching: concentrating two years' worth of charitable donations into one year, then taking the standard deduction the next. This lets you maximize the itemized deduction every other year while still benefiting from the standard deduction in between.
The Bottom Line
For most W-2 employees without a mortgage or major expenses, the standard deduction is the right call. For homeowners, those in high-tax states, and people with large charitable or medical expenses, itemizing often wins. Run the numbers — or let a tax preparer run them — before you assume one is always better.
