Direct Answer
For 2025, the standard deduction is $15,000 (single), $30,000 (married filing jointly), and $22,500 (head of household). Itemize only if your Schedule A deductions - mortgage interest, state and local taxes up to $40,000, charitable contributions, and medical expenses above 7.5% of AGI - add up to more than your standard deduction. Most taxpayers take the standard deduction. Itemizing typically makes sense for homeowners in high-tax states who pay significant mortgage interest and property taxes.
Key Takeaways
- The 2025 standard deduction is $15,000 (single/MFS), $30,000 (MFJ/QSS), and $22,500 (HOH) - all confirmed by IRS Rev. Proc. 2024-40.
- If you are 65 or older or legally blind, add $2,000 (single/HOH) or $1,600 per qualifying condition per person (MFJ/MFS) to your standard deduction.
- The OBBBA increased the SALT deduction cap from $10,000 to $40,000 for tax years 2025-2029, making itemizing more attractive in high-tax states.
- Medical expenses are only deductible on Schedule A to the extent they exceed 7.5% of your AGI - the floor is applied before adding them to your itemized total.
- The OBBBA $6,000 senior deduction is separate from this comparison. It is available whether you itemize or take the standard deduction.
- If you are married filing separately and your spouse itemizes, you must also itemize. You cannot take the standard deduction in that case.
- The TCJA suspended most miscellaneous itemized deductions through 2028. Unreimbursed employee expenses and tax preparation fees are not deductible for most filers.

What Is the Standard Deduction for 2025-2026?
The standard deduction is a flat dollar amount that reduces your taxable income without requiring you to list individual expenses. The IRS adjusts it annually for inflation. For 2025 (returns filed in 2026), the standard deduction is the highest it has been, reflecting years of inflation-indexed increases and the OBBBA's confirmation of TCJA deduction levels.

You are considered 65 for 2025 if you were born before January 2, 1961. The age and blind add-ons apply only when taking the standard deduction - they do not increase itemized deductions. The OBBBA $6,000 senior deduction is a separate above-the-line item and applies regardless of which deduction method you choose.
When Should You Itemize Your Deductions?
Itemize when your total Schedule A deductions exceed the standard deduction for your filing status. The main categories that push people into itemizing:
Homeowners with Significant Mortgage Interest
A homeowner with a $600,000 mortgage at 6.5% pays roughly $38,400 in interest in the first year. Combined with property taxes, that alone often exceeds the standard deduction for a single filer ($15,000).
Taxpayers in High-Tax States
The OBBBA SALT cap increase to $40,000 restored meaningful deductions for filers in California, New York, New Jersey, Massachusetts, Connecticut, and Illinois. A family paying $20,000 in state income taxes and $15,000 in property taxes previously had $25,000 of that capped at $10,000 under TCJA. Under the OBBBA, all $35,000 is deductible in 2025.
Large Charitable Givers
If you donate $20,000 or more annually, those contributions alone can push your itemized deductions above the standard deduction - especially when combined with mortgage interest or state taxes.
High Medical Expenses
Serious illness, surgery, or long-term care costs can generate deductible medical expenses once they clear the 7.5% AGI floor. A person with $80,000 AGI who spent $15,000 on unreimbursed medical expenses can deduct $9,000 ($15,000 - $6,000 floor).
How the SALT Deduction Change Affects Your Decision
The state and local tax deduction covers your state income taxes (or state sales taxes if higher), plus local income taxes, plus real estate property taxes. Starting with 2025 taxes, the OBBBA increased the cap from $10,000 to $40,000 - the largest change for itemizers since TCJA.
SALT phase-out: The $40,000 cap phases out for taxpayers with MAGI above $500,000. The reduction is $300 per $1,000 of MAGI over the threshold. The cap cannot fall below $10,000 - you always get at least $10,000 in SALT regardless of income. Married filing separately filers have a $20,000 cap and a $250,000 phase-out threshold.
For most taxpayers, MAGI and AGI are the same or close. The calculator uses your AGI input as a proxy for MAGI. If you have significant above-the-line exclusions (foreign earned income, etc.), your actual MAGI may differ.

The OBBBA $6,000 Senior Deduction Is Not Part of This Comparison
The One Big Beautiful Bill Act created a separate enhanced deduction of $6,000 per eligible person age 65 or older under IRC §70103. This is a Schedule 1-A deduction (above the line), not a Schedule A deduction. It is available whether you itemize or take the standard deduction.

How to Use This Calculator
- Select your 2025 filing status. If married filing separately, note that if your spouse itemizes, you must also itemize regardless of this calculator's recommendation.
- Check the boxes for age (born before January 2, 1961 counts as 65 for 2025) and blindness. These add to your standard deduction baseline.
- Enter your AGI from Form 1040 line 11. This is used for the 7.5% medical expense floor and the SALT phase-out if your income is above $500,000.
- Enter mortgage interest from Form 1098. Use only the interest you actually paid, not your loan balance or monthly payment.
- Enter total state and local taxes paid (state income tax from W-2 plus property tax bills). Enter the actual amount paid - the calculator caps it at $40,000 automatically.
- Enter charitable contributions. Cash gifts require a written receipt for amounts over $250.
- Enter total unreimbursed medical expenses. The calculator subtracts the 7.5% floor from this figure - only the excess counts.
- Click Compare. The results show both totals side by side and identify which deduction saves more - along with the dollar advantage and a breakdown of how each figure was calculated.
How This Calculator Computes Your Deduction Comparison
The calculator runs two parallel computations and returns the larger result with a full breakdown.
Standard Deduction Computation
Starts with the base amount for your filing status ($15,000 / $30,000 / $22,500). Adds $2,000 per qualifying condition (age or blindness) for single and HOH filers, or $1,600 per qualifying condition per person for MFJ, MFS, and QSS filers. Does not include the OBBBA $6,000 senior deduction, which is shown separately.
Itemized Deduction Computation
Sums five categories after applying statutory limits:
- Mortgage interest: Entered amount used as-is. The $750,000 acquisition debt cap is a loan-balance limit applied at the source - your Form 1098 already reflects deductible interest only.
- SALT: Capped at $40,000 for most filers ($20,000 MFS). If your AGI exceeds $500,000, the cap is reduced by $300 per $1,000 of excess but never below $10,000.
- Charitable contributions: Entered amount used as-is. The 60% AGI limit for cash gifts is not enforced here - enter only amounts within IRS limits.
- Medical expenses: Max(0, entered amount minus 7.5% of AGI). If your medical expenses do not clear the floor, this term is zero.
- Other deductions: Entered amount used as-is. Confirm eligibility before including - most miscellaneous itemized deductions are suspended through 2028.

Practitioner Insight: Three Itemizing Mistakes We See Regularly
Mistake 1 - Counting SALT Without Applying the Cap
A family in New Jersey paid $22,000 in property taxes and $18,000 in state income taxes. They enter $40,000 in SALT and believe their deduction is $40,000. It is - exactly at the cap. But a family that paid $28,000 property and $25,000 income taxes cannot deduct $53,000. Their deduction is capped at $40,000 regardless of how much they actually paid. Many taxpayers in high-tax states assume the cap no longer applies because it went from $10,000 to $40,000. The cap still applies. Only the number changed.
Mistake 2 - Entering Gross Medical Bills Instead of Out-of-Pocket
Only unreimbursed medical expenses count. If you paid $20,000 for surgery but your insurance reimbursed $14,000, your deductible amount is $6,000, not $20,000. This is before the 7.5% floor even applies. Enter what you actually paid from your own pocket - not what was billed, and not what insurance initially adjudicated.
Mistake 3 - Forgetting to Compare After Each Major Life Event
Whether to itemize is not a fixed decision. Buying a home, paying off a mortgage, moving to a no-income-tax state, having a high-medical-expense year, or making a large charitable gift can each flip the answer. Run this comparison every year. The standard deduction grows with inflation, but your actual deductible expenses change with your life circumstances.
The Rule We Apply
In any year where a client has a mortgage, significant SALT payments, or large charitable gifts, we run the itemized comparison before assuming standard deduction. The OBBBA SALT increase to $40,000 flipped the answer for many clients who had previously been locked into standard deduction by the $10,000 TCJA cap. When in doubt, calculate both - the higher number is always correct.
When the Standard vs Itemized Comparison Does Not Apply
- Married filing separately when your spouse itemizes - you must itemize regardless of whether your deductions exceed the standard. The standard deduction is not available to you in this case.
- Nonresident aliens filing Form 1040-NR - the standard deduction is generally not available unless you are a resident of India under Article 21(2) of the US-India tax treaty or have elected to be treated as a US resident.
- Dual-status aliens in the year of arrival or departure - special rules apply; the standard deduction is not available for the nonresident portion of the year.
- Returns for a period of less than 12 months due to an accounting period change - the standard deduction is not available for short-period returns.
- Large state income tax refunds - if you deducted state taxes in a prior year and received a state refund, that refund may be partially taxable in the year received (the tax benefit rule). This does not change the current-year comparison but affects prior-year deduction recovery.
- Alternative minimum tax - the SALT deduction is not allowed for AMT purposes. High-income itemizers should compare regular tax vs AMT. If AMT applies, the SALT benefit disappears in the AMT calculation even if you itemize for regular tax.
Next Steps After Running This Calculator
If You Should Itemize
Your SALT deduction is often the largest itemized deduction. Use the SALT Deduction Calculator to verify your exact deductible amount including the phase-out if your MAGI is above $500,000. If you are age 65 or older, also run the Senior Standard Deduction Calculator to compute your separate $6,000 OBBBA deduction.
If Standard Deduction Wins
The standard deduction is simpler and records are not required. If you are age 65 or older, still check the Senior Standard Deduction Calculator - the $6,000 OBBBA deduction is available above the standard deduction and may significantly reduce your tax bill regardless of your itemizing decision. For a full breakdown of deductible expenses on Schedule A, see the Complete List of Itemized Deductions.
If You Are Married and Unsure Which Status to Use
Your filing status determines which standard deduction applies. MFJ gets $30,000 and MFS gets $15,000 each. If one MFS spouse itemizes, the other must also itemize - they cannot take the standard deduction. Use the Filing Status Calculator to compare MFJ and MFS on your actual income before making this decision.

Frequently Asked Questions
What is the standard deduction for 2025?
For tax year 2025, the standard deduction is $15,000 for single filers and married filing separately, $30,000 for married filing jointly and qualifying surviving spouses, and $22,500 for heads of household. Taxpayers age 65 or older or blind can add $2,000 (single or head of household) or $1,600 per qualifying condition per person (married filers). Source: IRS Revenue Procedure 2024-40.
Should I itemize or take the standard deduction?
Itemize if your total Schedule A deductions exceed the standard deduction for your filing status. The main expenses that make itemizing worthwhile are mortgage interest, state and local taxes (capped at $40,000 for 2025), charitable contributions, and medical expenses above 7.5% of AGI. Most renters without significant other deductions take the standard deduction. Homeowners in high-tax states often find itemizing saves significantly more.
How does the SALT cap change for 2025 affect my decision?
The OBBBA increased the state and local tax deduction cap from $10,000 to $40,000 for tax years 2025 through 2029. This is the biggest change for itemizers since TCJA. Many taxpayers in high-tax states who had been taking the standard deduction because $10,000 SALT was not enough to exceed the standard deduction may now find that $40,000 SALT plus mortgage interest pushes them into itemizing territory.
Can I deduct home office expenses if I itemize?
Unreimbursed employee business expenses, including home office costs for W-2 employees, are not deductible for most filers through 2028. The TCJA suspended the 2% AGI miscellaneous itemized deductions and the OBBBA extended that suspension. Self-employed filers deduct home office expenses on Schedule C, not Schedule A - those deductions reduce AGI regardless of whether you itemize or take the standard deduction.
What is the medical expense floor for 2025?
The threshold is 7.5% of your adjusted gross income. Only unreimbursed medical and dental expenses above this floor are deductible on Schedule A. For example, with $70,000 AGI, the floor is $5,250. If you paid $10,000 in unreimbursed medical expenses, only $4,750 is deductible. This threshold was made permanent at 7.5% by the TCJA and confirmed under the OBBBA.
Does the OBBBA $6,000 senior deduction count as an itemized deduction?
No. The OBBBA $6,000 enhanced senior deduction under §70103 is a Schedule 1-A above-the-line deduction. It is available whether you itemize or take the standard deduction. The age and blind add-ons under §63(f) (the $2,000/$1,600 amounts) increase only the standard deduction and do not apply when itemizing. The $6,000 senior deduction is entirely separate and always stacks on top of whichever deduction method you choose.
Can I switch between itemizing and standard deduction each year?
Yes. You are not locked into a method. Each tax year stands alone. If your itemized deductions exceed the standard deduction in a given year, itemize that year. If they do not, take the standard deduction. Many taxpayers alternate - for example, itemizing in a high-donation year and taking standard deduction in normal years. The calculation is made fresh each year using that year's figures and standard deduction amounts.
Is property tax fully deductible if I pay it on a rental property?
Property taxes on rental properties are deducted on Schedule E as a rental expense, not on Schedule A. The SALT cap on Schedule A applies only to personal-use state and local taxes on your primary and secondary residences. Rental property taxes are a business deduction and are not subject to the $40,000 SALT cap. Enter only the property taxes on your personal residence(s) in this calculator.
