How do I know if itemizing saves me money?

Standard vs Itemizedbeginner3 answers · 5 min readUpdated February 28, 2026

Quick Answer

Itemizing saves money if your deductible expenses exceed the standard deduction: $15,000 (single) or $30,000 (married filing jointly) for 2026. About 13% of taxpayers itemize because most don't have enough deductions to beat the standard amount.

How to calculate if itemizing saves you money


Itemizing saves money when your total deductible expenses exceed the standard deduction. For 2026, that threshold is $15,000 for single filers and $30,000 for married couples filing jointly.


The math is simple: Add up your potential itemized deductions and compare to your standard deduction amount. If itemized is higher, you save money. If not, stick with the standard deduction.


Example: Single filer with $18,000 in deductions


Sarah is single and earned $75,000 in 2026. Her potential itemized deductions include:


  • State and local taxes (SALT): $10,000 (capped)
  • Mortgage interest: $6,500
  • Charitable donations: $1,500
  • Total itemized deductions: $18,000

  • Since $18,000 exceeds the $15,000 standard deduction, Sarah saves money by itemizing. Her tax savings: ($18,000 - $15,000) × 22% marginal rate = $660 extra tax savings.



    Main categories of itemized deductions


  • State and local taxes (SALT): Up to $10,000 cap for state income/sales tax plus property tax
  • Mortgage interest: Interest on up to $750,000 in mortgage debt
  • Charitable donations: Generally up to 60% of adjusted gross income
  • Medical expenses: Only the amount exceeding 7.5% of your AGI
  • Casualty and theft losses: Only federally declared disasters, exceeding 10% of AGI

  • Key factors that make itemizing worthwhile


  • High property taxes + state income tax: If you live in a high-tax state and own a home, you'll likely hit the $10,000 SALT cap
  • Large mortgage: Higher mortgage interest pushes you closer to the itemizing threshold
  • Significant charitable giving: Regular donors to charity often benefit from itemizing
  • Major medical expenses: High out-of-pocket medical costs can tip the scales

  • What you should do


    1. Gather your tax documents (1098 mortgage interest, property tax statements, charitable receipts)

    2. Add up your potential itemized deductions

    3. Compare to your standard deduction amount

    4. Use our return scanner tool to identify deductions you might have missed


    If you're close to the threshold, consider timing strategies like bunching charitable donations into alternating years.


    Key takeaway: Itemizing saves money when your deductions exceed $15,000 (single) or $30,000 (married). Most taxpayers don't reach this threshold, but homeowners with mortgages and charitable givers often do.

    Best for homeowners evaluating their mortgage interest and property tax deductions

    Why homeowners are most likely to benefit from itemizing


    As a homeowner, you have access to two major deduction categories that renters don't: mortgage interest and property taxes. These alone often push you over the standard deduction threshold.


    Example: Homeowner analysis


    Mike and Lisa are married homeowners in Texas with a $400,000 mortgage at 6.5% interest:


  • Mortgage interest: $25,000 (first year of loan)
  • Property taxes: $8,000
  • State sales tax: $2,000 (Texas has no income tax)
  • Charitable donations: $3,000
  • Total: $38,000

  • Since $38,000 exceeds the $30,000 standard deduction, they save an extra $1,920 in taxes (at 24% marginal rate) by itemizing.


    When homeowners should still take the standard deduction


  • Small mortgage or paid-off home: Low interest payments
  • Low property tax areas: Rural areas with low property values
  • Recent refinance to lower rate: Less interest to deduct

  • Even homeowners should run the numbers annually, as mortgage interest decreases over time while the standard deduction may increase with inflation adjustments.


    Key takeaway: Homeowners with mortgages over $200,000 or property taxes over $5,000 annually should always compare itemizing vs. standard deduction.

    Best for W-2 employees with straightforward tax situations

    Why most W-2 employees take the standard deduction


    If you're a W-2 employee who rents your home, you likely lack the major deduction categories (mortgage interest, property taxes) that make itemizing worthwhile. The 2017 tax reform nearly doubled the standard deduction while eliminating many employee deductions.


    Deductions W-2 employees lost in 2018


  • Unreimbursed employee expenses
  • Tax preparation fees
  • Investment advisory fees
  • Union dues (unless state allows)

  • When W-2 employees might still itemize


  • High charitable giving: Donating 20%+ of income to charity
  • Major medical expenses: Surgery, chronic illness treatments exceeding 7.5% of AGI
  • Casualty losses: Home damaged in federally declared disaster
  • High state taxes: Living in high-tax states like California or New York

  • Example: W-2 employee who should itemize


    Jenna earns $60,000, rents her apartment, but had $12,000 in medical expenses after a surgery:


  • Medical expenses above 7.5% AGI: $12,000 - $4,500 = $7,500
  • State income tax: $3,000
  • Charitable donations: $2,000
  • Property tax (none - she rents): $0
  • Total: $12,500

  • Since $12,500 is less than the $15,000 standard deduction, Jenna should take the standard deduction despite significant medical expenses.


    Key takeaway: Most W-2 employees benefit from the standard deduction unless they have extraordinary medical expenses, very high charitable giving, or live in high-tax states.
