Standard vs Itemized Comparison
How to Use This Standard vs Itemized Calculator
Enter your state and local taxes (SALT), mortgage interest, charitable donations, and medical expenses. The calculator automatically applies the SALT cap, 7.5% AGI floor for medical expenses, and compares your itemized total to the standard deduction for your filing status.
The Formula
SALT Deductible = min(SALT paid, $10,000)
Medical Deductible = max(0, Medical Expenses β 7.5% Γ AGI)
Total Itemized = SALT + Mortgage Interest + Charitable + Medical + Other
Extra Savings = (Total Itemized β Standard Deduction) Γ Marginal Rate
Medical Deductible = max(0, Medical Expenses β 7.5% Γ AGI)
Total Itemized = SALT + Mortgage Interest + Charitable + Medical + Other
Extra Savings = (Total Itemized β Standard Deduction) Γ Marginal Rate
Example
Jennifer, Married Filing Jointly, $150,000 AGI:
SALT: $10,000 (capped) + Mortgage interest: $14,000 + Charitable: $3,000 = $27,000
Standard deduction: $30,000
Result: Take standard deduction β saves $3,000 more
She would need $3,001+ more in deductible expenses to benefit from itemizing.
SALT: $10,000 (capped) + Mortgage interest: $14,000 + Charitable: $3,000 = $27,000
Standard deduction: $30,000
Result: Take standard deduction β saves $3,000 more
She would need $3,001+ more in deductible expenses to benefit from itemizing.

Deduction Bunching Strategy
How to bunch deductions into alternate years for maximum tax savings
Deduction Bunching Strategy
If your itemized deductions are close to the standard deduction, bunching them into alternate years can increase your total deduction over 2 years.

How to Implement Bunching
- Charitable donations: Give two years of planned donations in one year (or use a donor-advised fund)
- Property taxes: Prepay next year's property taxes in December (if below $10K SALT cap)
- Medical procedures: Schedule elective procedures in the high-deduction year
- Donor-Advised Fund (DAF): Contribute a large lump sum to a DAF in the bunching year, then distribute to charities over multiple years
When Bunching Works Best
- Your itemized deductions are 70-95% of your standard deduction amount
- You have flexible charitable giving (can shift timing by a few months)
- You're in the 22%+ tax bracket (larger benefit from extra deductions)
- You have predictable income and expenses each year
Frequently Asked Questions
What is the standard deduction for 2025?
The 2025 standard deduction is $15,000 for single filers, $30,000 for married filing jointly, $15,000 for married filing separately, and $22,500 for head of household. These amounts were increased from 2024 due to inflation adjustments.
What expenses can I include in itemized deductions?
Itemized deductions include: state and local taxes (SALT, capped at $10,000), mortgage interest on loans up to $750,000, charitable contributions (up to 60% of AGI for cash), and medical expenses exceeding 7.5% of AGI. Other deductions include casualty losses in federally declared disaster areas.
What is the SALT deduction cap?
The Tax Cuts and Jobs Act (TCJA) capped the state and local tax (SALT) deduction at $10,000 ($5,000 for married filing separately). This cap includes property taxes plus state income or sales taxes. The cap is currently scheduled to expire after 2025, but legislation may extend it.
Can I switch between standard and itemized deductions each year?
Yes, you can choose whichever method gives you a lower tax bill each year. You are not locked into one method. Many taxpayers with variable expenses (like large charitable donations some years) may switch back and forth.
What is the bunching strategy for itemized deductions?
Bunching means concentrating itemized deductions into alternate years β giving large charitable donations every other year, or prepaying property taxes. In "bunching" years you itemize; in other years you take the standard deduction. This can yield a larger total deduction over 2 years than taking standard both years.
