One of the most important decisions on your tax return is whether to take the standard deduction or itemize. For the vast majority of taxpayers, the standard deduction is the better choice — but not always. Here is how to decide for 2025.
2025 Standard Deduction Amounts
The IRS has increased the standard deduction for 2025 to account for inflation:
| Filing Status | Standard Deduction |
|---|---|
| Single | $15,000 |
| Married Filing Jointly | $30,000 |
| Married Filing Separately | $15,000 |
| Head of Household | $22,500 |
Taxpayers age 65 or older get an additional $1,950 (single/HOH) or $1,550 per spouse (married filing jointly).
When Does Itemizing Make Sense?
You should itemize only if your total itemized deductions exceed the standard deduction. The most common itemized deductions include:
- State and local taxes (SALT): Property taxes plus state income or sales taxes, capped at $10,000 total. This cap, introduced by the 2017 Tax Cuts and Jobs Act, remains in effect for 2025.
- Mortgage interest: On loans up to $750,000 for homes purchased after December 15, 2017.
- Charitable contributions: Cash donations up to 60% of AGI, plus fair market value of donated property.
- Medical expenses: Only the amount exceeding 7.5% of your adjusted gross income (AGI).
The SALT Cap Impact
Before 2018, taxpayers in high-tax states like California, New York, and New Jersey could deduct the full amount of their state and local taxes. The $10,000 SALT cap dramatically reduced the value of itemizing for many of these filers. A homeowner paying $15,000 in property taxes and $12,000 in state income tax can only deduct $10,000 total — losing $17,000 in deductions compared to the old rules.
A Quick Decision Framework
You are likely better off with the standard deduction if:
- You rent rather than own a home
- You live in a low-tax state
- Your mortgage is small or paid off
- Your charitable giving is modest
Itemizing may save you more if:
- You have a large mortgage on a high-value home
- You make substantial charitable donations
- You had major unreimbursed medical expenses
- Your combined deductions clearly exceed the standard deduction threshold
Practical Example
Consider a married couple in 2025 with:
- $10,000 in SALT (at the cap)
- $14,000 in mortgage interest
- $8,000 in charitable donations
Their total itemized deductions would be $32,000, which exceeds the $30,000 standard deduction by $2,000. At the 22% bracket, that saves them $440 — enough to be worthwhile, but close enough that they should double-check their numbers.
Do Not Forget: Bunching Strategy
If your itemized deductions are close to the standard deduction, consider bunching — concentrating two years of charitable donations into one year so you can itemize in the high year and take the standard deduction in the other year. Donor-advised funds make this strategy especially easy.
Bottom Line
About 87% of taxpayers take the standard deduction, and for good reason: the 2025 amounts are generous. But if you have significant mortgage interest, charitable giving, or medical expenses, run the numbers both ways before filing.
