Standard Deduction vs Itemized Deductions: Which Saves You More?

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.

2026 standard deduction amounts:

Filing Status	Standard Deduction
Single	$15,000
Married Filing Jointly	$30,000
Married Filing Separately	$15,000
Head of Household	$22,500

Additional amounts for age 65+ or legally blind: $1,550 (single) / $1,250 per spouse (MFJ).

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 $10,000 per return. Even if you paid $20,000 in property taxes, only $10,000 counts.

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 $600,000 mortgage at 7% pays roughly $42,000 in interest the first year. Add $10,000 SALT cap + $5,000 charitable giving = $57,000 in deductions vs. the $30,000 standard. Itemizing wins by $27,000.

High state income tax states: California, New York, New Jersey residents often pay $10,000+ in state taxes alone, maxing 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, $80,000 income):

• Mortgage interest: $12,000
• Property taxes + state income tax: $10,000 (SALT cap)
• Charitable donations: $2,500
• Total itemized: $24,500
• Standard deduction: $15,000
• Verdict: Itemize and save $9,500 more

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.
