Standard Deduction vs Itemized Deductions: Which Saves You More?

Every taxpayer must choose between two ways to reduce their taxable income: the standard deduction or itemized deductions. You can only use one method per year, so understanding when to itemize — and when to stick with the standard — can save you hundreds or even thousands of dollars.

The Standard Deduction in 2026

The standard deduction is a flat dollar amount that reduces your taxable income. No receipts, no calculations — you just take it.

Standard deduction amounts (IRS):

Additional amounts for age 65+ or legally blind, per qualifying condition: $2,000 if single or head of household and $1,600 if married for 2025; $2,050 if unmarried and $1,650 if married for 2026.

After the Tax Cuts and Jobs Act of 2017 roughly doubled the standard deduction, approximately 90% of taxpayers now take the standard deduction rather than itemizing.

What Are Itemized Deductions?

Itemized deductions are specific expenses the IRS allows you to subtract from your gross income. They're listed on Schedule A and include:

1. Mortgage Interest

Interest paid on a primary or secondary home mortgage (up to $750,000 in loan principal). This is typically the biggest itemized deduction for homeowners.

2. State and Local Taxes (SALT)

The combined deduction for state income taxes (or sales taxes) plus local property taxes is capped at $40,000 per return for 2025 and $40,400 for 2026 ($20,000 and $20,200 if married filing separately). The cap is reduced when modified AGI is more than $500,000 for 2025 or $505,000 for 2026, but not below $10,000 ($5,000 if married filing separately).

3. Charitable Contributions

Cash donations to qualifying 501(c)(3) organizations are fully deductible (up to 60% of AGI). Non-cash donations (clothing, household goods) require a receipt.

4. Medical and Dental Expenses

Only expenses exceeding 7.5% of your adjusted gross income are deductible. On a $70,000 income, you'd need more than $5,250 in medical expenses before a single dollar counts.

5. Casualty and Theft Losses

Limited to federally declared disaster areas only under current law.

6. Gambling Losses

Deductible, but only up to the amount of gambling winnings you reported.

When Itemizing Beats the Standard Deduction

Itemizing pays off when your qualifying expenses add up to more than your standard deduction. Run the math in these common scenarios:

Homeowners with large mortgages: A couple with a large mortgage, sizable state and local taxes and regular charitable giving can end up with itemized deductions above the joint-return standard deduction ($31,500 for 2025 returns, $32,200 for 2026). If their total is larger, itemizing wins.

High state income tax states: California, New York and New Jersey residents often pay large state and local tax bills, which count toward the SALT cap. If they also have mortgage interest, itemizing frequently beats the standard.

Large charitable donors: Donating $20,000 per year? Combined with other deductions, you likely exceed the standard deduction threshold.

High medical expenses: After major surgery, cancer treatment, or long-term care costs, medical expenses can easily exceed 7.5% of AGI and push total itemized deductions above the standard amount.

How to Calculate Which Is Better

1. Add up all your qualifying itemized deductions
2. Compare the total to your standard deduction
3. Choose whichever is larger

Example (single filer): add up mortgage interest, state and local taxes (up to the SALT cap) and charitable gifts, then compare the total with the single standard deduction ($15,750 for 2025 returns, $16,100 for 2026). Itemize only if your total is larger.

Common Mistakes When Deciding

• Not tracking donations: Small recurring gifts add up. $50/month = $600/year.
• Forgetting investment interest: If you borrowed to buy investments, the interest may be deductible.
• Missing self-employment deductions: These go on Schedule C (not Schedule A), so they reduce income regardless of whether you itemize.
• Assuming homeownership always means itemizing: With a modest mortgage and low property taxes, the standard deduction may still win.

The Bottom Line

Most Americans take the standard deduction — it's simpler and often larger. But if you own a home with a significant mortgage, pay high state taxes, or have large deductible expenses, itemizing can substantially reduce your tax bill. Pull out a calculator before you choose.
