Standard Deduction vs. Itemizing in 2026: Which Strategy Wins Under OBBBA?
Every April, millions of Americans face a critical decision: should I take the standard deduction or itemize my deductions? This year, that decision is even more important. The OBBBA of 2026 raised the SALT (State and Local Tax) deduction cap from $10,000 to $40,000, making itemization attractive to a broader range of high-income households. Meanwhile, the standard deduction also increased with inflation. The result: some taxpayers who previously didn't benefit from itemization now save thousands by itemizing, while others should stick with the standard deduction. Here's the complete framework to decide which strategy is right for you.
2026 Standard Deductions
First, the baseline: what is the standard deduction for 2026?
2026 Standard Deduction Amounts:
- Single: $15,000
- Married Filing Jointly (MFJ): $30,000
- Married Filing Separately (MFS): $15,000
- Head of Household (HOH): $22,500
- Qualifying Widow(er): $30,000
For Taxpayers Age 65 or Older (2026):
- Single: $15,000 + $2,000 = $17,000
- MFJ (one spouse 65+): $30,000 + $1,550 = $31,550
- MFJ (both spouses 65+): $30,000 + $3,100 = $33,100
- HOH: $22,500 + $2,500 = $25,000
These amounts increased from 2025 due to annual inflation adjustments. The standard deduction is indexed to inflation and rises each year.
What Can You Itemize?
When you itemize, you add up eligible deductions and report them on Schedule A. Here's what qualifies for 2026:
Fully Deductible Items (No Limitations)
State and Local Taxes (SALT) — up to $40,000 total
- State income tax (or sales tax in some cases)
- Local income tax (NYC, Philadelphia, etc.)
- Property tax
- The $40,000 cap is NEW under OBBBA and is the biggest change for 2026
Mortgage Interest — Limited to $750,000 of debt
- Interest on your primary residence and one secondary residence
- Interest on home equity loans (debt used to acquire, construct, or improve a home)
- Not deductible on home equity loans used for other purposes (under current law)
Charitable Contributions
- Cash donations to IRS-qualified charities (100% of AGI for most taxpayers in 2026)
- Appreciated property donations (50%, 30%, or 20% of AGI depending on asset type)
- Donor-advised fund contributions
- Bunching strategy: Donate in alternate years to maximize deduction in some years
Partially Deductible Items (Subject to Limitations)
Medical Expenses
- Only expenses exceeding 7.5% of your adjusted gross income
- Includes insurance premiums, prescriptions, doctor visits, hospital costs, dental, vision, hearing aids, etc.
- Example: AGI $100,000 → only medical expenses over $7,500 are deductible
Investment Interest (Rarely Deductible)
- Only interest on money borrowed to buy taxable investments (not retirement accounts)
- Limited to investment income for the year
- Usually not significant for most taxpayers
NOT Deductible (Starting in 2026 Under OBBBA)
- Employee business expenses (eliminated)
- Hobby losses (never deductible)
- Personal expenses
- Federal income tax
- Self-employment tax (though you can deduct half of it above the line)
- Alimony (if divorce/separation after 2018)
The Decision Tree: Should You Itemize?
Here's the simple rule:
Itemize if: Your total itemized deductions exceed your standard deduction Take standard deduction if: Your total itemized deductions are less than your standard deduction
For example:
- Single filer, standard deduction: $15,000
- Your SALT + mortgage interest + charitable giving = $22,000
- Itemize: Deduction of $22,000 beats $15,000 standard deduction
But if:
- Your SALT + mortgage interest + charitable giving = $12,000
- Take standard deduction: $15,000 beats $12,000 itemized
Real-World Scenarios: Five Household Examples
Let's walk through five different households to see who benefits from itemization in 2026.
Scenario 1: High-Income New York City Homeowner (MFJ)
Profile:
- Married filing jointly, NYC resident
- Combined income: $400,000
- Home value: $1,500,000 (mortgage balance: $750,000)
- Annual mortgage interest: $30,000
- NYC real estate tax: $25,000
- NY state income tax: $22,000
- Charitable giving: $15,000
Deduction Calculation:
- SALT deduction: $25,000 (property tax) + $22,000 (state income tax) = $47,000 → capped at $40,000
- Mortgage interest: $30,000
- Charitable giving: $15,000
- Total itemized deductions: $85,000
- Standard deduction: $30,000
- Decision: Itemize
- Benefit: $55,000 additional deductions at 35% bracket = $19,250 tax savings
Scenario 2: Middle-Income Texas Homeowner (MFJ)
Profile:
- Married filing jointly, Texas resident (no state income tax)
- Combined income: $180,000
- Home value: $600,000 (mortgage balance: $400,000)
- Annual mortgage interest: $15,000
- Property tax (TX): $8,000
- Charitable giving: $4,000
Deduction Calculation:
- SALT deduction: $8,000 (property tax, no state income tax in TX)
- Mortgage interest: $15,000
- Charitable giving: $4,000
- Total itemized deductions: $27,000
- Standard deduction: $30,000
- Decision: Take standard deduction
- The $30,000 standard deduction exceeds the $27,000 itemized total
Scenario 3: High-Earning Connecticut Business Owner (Single)
Profile:
- Single, Connecticut resident
- Income: $250,000
- Home value: $1,200,000 (mortgage balance: $600,000)
- Annual mortgage interest: $18,000
- Connecticut property tax: $18,000
- Connecticut state income tax: $15,000
- Charitable giving: $8,000
Deduction Calculation:
- SALT deduction: $18,000 + $15,000 = $33,000 (below $40K cap, fully deductible)
- Mortgage interest: $18,000
- Charitable giving: $8,000
- Total itemized deductions: $59,000
- Standard deduction: $15,000
- Decision: Itemize
- Benefit: $44,000 additional deductions at 32% bracket = $14,080 tax savings
Scenario 4: Senior Married Couple (HOH, Age 70)
Profile:
- Head of household, age 70
- Income: $100,000
- Home value: $400,000 (paid off, no mortgage)
- Property tax: $6,000
- State income tax: $3,000
- Charitable giving: $5,000
- Medical expenses: $12,000 (but must exceed 7.5% of $100K = $7,500)
Deduction Calculation:
- SALT deduction: $6,000 + $3,000 = $9,000
- Mortgage interest: $0 (home paid off)
- Charitable giving: $5,000
- Medical expenses (over 7.5% of AGI): $12,000 - $7,500 = $4,500
- Total itemized deductions: $18,500
- Standard deduction (age 65+ HOH): $25,000 (higher)
- Decision: Take standard deduction
- Even though medically expensive, the high standard deduction for seniors makes itemization unnecessary
Scenario 5: High-Net-Worth San Francisco Investor (MFJ)
Profile:
- Married filing jointly, San Francisco resident
- Investment income: $300,000 (capital gains, dividends)
- Home value: $2,500,000 (mortgage balance: $800,000)
- Annual mortgage interest: $23,000
- California state income tax: $35,000
- Property tax (CA): $28,000
- Charitable giving: $20,000
Deduction Calculation:
- SALT deduction: $28,000 + $35,000 = $63,000 → capped at $40,000 under OBBBA
- Mortgage interest: $23,000
- Charitable giving: $20,000
- Total itemized deductions: $83,000
- Standard deduction: $30,000
- Decision: Itemize
- Benefit: $53,000 additional deductions at 37% bracket = $19,610 tax savings
Note: Even though this couple's SALT is $63,000, the $40,000 cap limits their deduction. They still benefit from itemization, but the SALT cap "costs" them $23,000 in uncapped deductions.
The SALT Cap Impact Under OBBBA
The $40,000 SALT cap is critical to understand:
Before OBBBA (2025): $10,000 cap meant many high earners in high-tax states couldn't deduct much of their SALT
Under OBBBA (2026): $40,000 cap allows:
- New Jerseyans with $45,000 in SALT to deduct $40,000 (vs. only $10,000 before)
- Californians with $60,000 in SALT to deduct $40,000 (vs. only $10,000 before)
- But ultra-wealthy residents (SALT over $40,000) still hit the ceiling
The $40,000 cap is a significant expansion but remains a cap—it doesn't help families with SALT exceeding $40,000.
Bunching Strategy: Alternate-Year Itemizing
If your itemized deductions are close to the standard deduction (within $5,000-10,000), consider a bunching strategy:
Bunching Example:
Year 1 (Bunching Year):
- Charitable giving: $15,000 (instead of $7,500/year)
- Mortgage interest: $20,000
- SALT: $18,000
- Total itemized: $53,000 (exceeds $30,000 standard deduction)
- Itemize and save $23,000 in deductions
Year 2 (Non-Bunching Year):
- Charitable giving: $0 (saved in Year 1)
- Mortgage interest: $20,000
- SALT: $18,000
- Total itemized: $38,000 (exceeds standard deduction)
- Take standard deduction ($30,000) and save only $8,000
2-Year Total Deductions: $53,000 (Year 1) + $30,000 (Year 2) = $83,000 vs. Regular 2-Year Deductions: $46,000 + $46,000 = $92,000
Actually, this example shows bunching doesn't always help unless you're close to the threshold. But for borderline cases, bunching can increase total deductions over a two-year cycle.
Bunching Tools:
- Donor-Advised Funds (DAFs): Contribute $20,000 to a DAF in Year 1 (deductible immediately), then distribute to charities over Years 1-3. Creates a tax deduction spike in Year 1.
- Charitable gift annuities: Similar bunching effect.
- Accelerated charitable giving: Pay next year's charitable commitment in December of the current year.
The Mortgage Interest Deduction: Still Valuable in 2026
While the mortgage interest deduction has limitations, it remains one of the most valuable itemized deductions for homeowners:
2026 Mortgage Interest Deduction Limits:
- Deductible on loans up to $750,000 of principal (combined primary + secondary residence)
- Interest on home equity lines of credit (HELOCs) is deductible only if used to buy, construct, or substantially improve the home
- Interest on purchases made before December 16, 2017, can be deducted on loans up to $1 million
Real Impact:
- Homeowner with $500,000 mortgage at 6% interest = $30,000/year in deductible interest
- At 22% tax bracket = $6,600 annual tax savings
- Over 30-year mortgage = $198,000 in cumulative tax savings
For homeowners, the mortgage interest deduction combined with SALT (now up to $40,000) often makes itemization worthwhile.
Medical Expenses: When They Help
Medical expenses only become deductible once they exceed 7.5% of your adjusted gross income. This is a high bar:
Threshold Examples:
- AGI $75,000: Medical expenses over $5,625 are deductible
- AGI $150,000: Medical expenses over $11,250 are deductible
- AGI $300,000: Medical expenses over $22,500 are deductible
Who Benefits:
- Retirees with high out-of-pocket costs (prescriptions, assisted living, private duty care)
- Families with chronic illnesses or disabilities
- People paying for long-term care or nursing facilities
For most middle-income families, medical expenses don't exceed the 7.5% threshold and thus don't help itemization.
Charitable Giving: The Ultimate Deduction
Charitable contributions are fully deductible (within limits based on AGI and asset type). For high earners, this is one of the easiest ways to exceed the standard deduction:
2026 Charitable Contribution Limits:
- Cash contributions: Up to 100% of AGI for most taxpayers
- Appreciated securities: Up to 30% of AGI
- Real estate: Up to 30% of AGI
Example:
- Income: $200,000
- Annual charitable giving: $12,000
- Combined with $25,000 SALT + $18,000 mortgage interest = $55,000 itemized
- This exceeds the $30,000 MFJ standard deduction by $25,000
For high earners who support charities, bunching giving via a Donor-Advised Fund can create meaningful tax deductions and make itemization worthwhile.
Action Steps: Decide Your 2026 Strategy
Calculate your total potential itemized deductions:
- SALT (property tax + state income tax + local income tax, capped at $40,000)
- Mortgage interest (if applicable)
- Charitable giving
- Medical expenses (only over 7.5% of AGI)
Compare to your 2026 standard deduction (based on filing status and age)
If itemized exceeds standard deduction by $2,000+: Itemize If standard exceeds itemized by $2,000+:** Take standard deduction If they're within $1,000:** Consider whether any tax planning changes (bunching, charitable timing) could tilt the scales
For borderline cases: Consider bunching charitable giving into alternate years using a Donor-Advised Fund
Update Form W-4: If itemizing significantly more than last year, your withholding may be off. Adjust to avoid a large tax bill in April 2027.
Key Takeaways
The OBBBA SALT cap increase to $40,000 is a game-changer for high-income households in high-tax states, making itemization attractive to many who couldn't benefit before.
2026 standard deductions are: Single $15,000 / MFJ $30,000 / HOH $22,500 (plus extra for those 65+)
Itemize if your SALT + mortgage interest + charitable giving + medical expenses exceed your standard deduction.
The SALT cap benefits most households in states with high income or property taxes (NY, CA, NJ, IL, MA, CT, etc.), but high earners with SALT over $40,000 still hit the ceiling.
Bunching charitable giving via Donor-Advised Funds can be a powerful strategy for households on the borderline of itemization.
For homeowners with mortgages and charitable interests in high-tax states, itemization is almost certainly better than the standard deduction in 2026.
Run the numbers for your specific situation, but if you live in a high-tax state and earn over $200,000, itemization is highly likely to be your optimal strategy in 2026.
