Yes, itemized deductions can increase your tax refund—but only when the total of your itemized expenses exceeds the standard deduction for your filing status. The IRS allows you to choose between taking a flat standard deduction or listing out specific expenses you paid during the year. Internal Revenue Code Section 63 creates this either-or choice, and selecting the wrong option can leave money on the table or result in a smaller refund than you deserve.
About 90% of taxpayers now take the standard deduction rather than itemizing—a dramatic shift from 2017, when roughly 31% itemized. The Tax Cuts and Jobs Act of 2017 nearly doubled the standard deduction while capping or eliminating several itemized deductions, making it harder for many filers to benefit from itemizing.

How The Standard Deduction Works in 2025 and 2026
The standard deduction reduces your taxable income by a fixed dollar amount based on your filing status. You do not need to track receipts or prove expenses. The IRS automatically gives you this deduction if you choose not to itemize.
For the 2025 tax year, the One Big Beautiful Bill Act (OBBBA) increased the standard deduction amounts by approximately 7.9% from 2024. The 2026 amounts have also been released by the IRS.
| Filing Status | 2025 Standard Deduction | 2026 Standard Deduction |
|---|---|---|
| Single | $15,750 | $16,100 |
| Married Filing Separately | $15,750 | $16,100 |
| Married Filing Jointly | $31,500 | $32,200 |
| Head of Household | $23,625 | $24,150 |
| Surviving Spouse | $31,500 | $32,200 |
If you are 65 or older, you qualify for an additional standard deduction of $2,000 (single/head of household) or $1,600 per spouse (married filing jointly). The OBBBA also created a new senior bonus deduction of up to $6,000 for qualifying taxpayers age 65 and older with modified adjusted gross income below $75,000 (single) or $150,000 (joint).
What Itemized Deductions Are and How They Reduce Your Tax Bill
Itemized deductions are specific expenses the IRS allows you to subtract from your adjusted gross income (AGI). Unlike the standard deduction, you must list and document each eligible expense on Schedule A attached to your Form 1040.
When you itemize, the total of all your qualifying expenses becomes your deduction. If that total exceeds the standard deduction for your filing status, itemizing will result in a lower taxable income and potentially a larger refund (or smaller tax bill).
The main categories of itemized deductions include:
| Category | Description | Key Limitation |
|---|---|---|
| Medical & Dental Expenses | Out-of-pocket costs not reimbursed by insurance | Only amounts exceeding 7.5% of AGI |
| State and Local Taxes (SALT) | Income/sales tax + property taxes | Capped at $40,000 (2025) |
| Mortgage Interest | Interest on home acquisition debt | Limited to $750,000 of debt |
| Charitable Contributions | Donations to qualified organizations | Up to 60% of AGI for cash gifts |
| Casualty & Theft Losses | Losses from federally or state-declared disasters | Must exceed 10% of AGI after $100 reduction |
| Other Deductions | Gambling losses, certain investment expenses | Gambling losses limited to winnings |
The Math Behind Whether Itemizing Increases Your Refund
The core principle is straightforward: you benefit from itemizing only when your total itemized deductions exceed your standard deduction. The excess amount is what provides additional tax savings.
Your marginal tax rate determines how much each extra dollar of deductions saves you. A taxpayer in the 22% bracket saves 22 cents for every dollar of deductions above the standard deduction threshold.
| Scenario | Standard Deduction Benefit | Itemized Deduction Benefit | Better Choice |
|---|---|---|---|
| Single filer with $12,000 itemized expenses | $15,750 reduction | $12,000 reduction | Standard |
| Single filer with $18,000 itemized expenses | $15,750 reduction | $18,000 reduction | Itemize |
| Married couple with $28,000 itemized expenses | $31,500 reduction | $28,000 reduction | Standard |
| Married couple with $38,000 itemized expenses | $31,500 reduction | $38,000 reduction | Itemize |
A married couple with $38,000 in itemized deductions would see $6,500 more in deductions than the standard amount. In the 22% bracket, this translates to approximately $1,430 in additional tax savings. If their withholding remained the same, this extra savings would increase their refund by that amount.
The $40,000 SALT Cap: A Game-Changer for High-Tax State Residents
The state and local tax (SALT) deduction allows you to deduct property taxes plus either state income taxes or state sales taxes (but not both). The TCJA capped this deduction at $10,000 starting in 2018, devastating taxpayers in high-tax states who previously had no limit.
The One Big Beautiful Bill Act quadrupled this cap to $40,000 for 2025 through 2029. This is the most significant change affecting whether itemizing now makes sense for you.
| Tax Year | SALT Cap (Most Filers) | Married Filing Separately Cap |
|---|---|---|
| 2024 | $10,000 | $5,000 |
| 2025 | $40,000 | $20,000 |
| 2026 | $40,400 | $20,200 |
| 2027 | $40,800 | $20,400 |
| 2030+ | $10,000 (reverts) | $5,000 |
There is an income-based phaseout. For taxpayers with modified AGI exceeding $500,000 in 2025, the SALT cap is reduced by 30% of the excess income. The cap cannot go below $10,000 regardless of income.
Example: A married couple in New York with MAGI of $540,000 exceeds the $500,000 threshold by $40,000. Their SALT cap is reduced by $12,000 ($40,000 × 30%), leaving them with a maximum SALT deduction of $28,000 instead of $40,000.
Taxpayers in California, New York, New Jersey, and Connecticut stand to benefit most from the increased cap because these states have the highest combined income and property tax burdens.
Mortgage Interest Deduction: The Homeowner’s Key Tax Break
If you have a mortgage, you can deduct the interest you pay on loans used to buy, build, or substantially improve your home. The deduction is limited to interest on the first $750,000 of mortgage debt ($375,000 if married filing separately).
For mortgages taken out before December 16, 2017, the limit is higher: you can deduct interest on up to $1 million of debt ($500,000 if married filing separately). The OBBBA made the $750,000 limit permanent for new loans.
| Loan Origin Date | Maximum Deductible Debt | MFS Limit |
|---|---|---|
| Before Dec. 16, 2017 | $1,000,000 | $500,000 |
| After Dec. 15, 2017 | $750,000 | $375,000 |
Home equity loan interest is deductible only if the funds were used to substantially improve the home. Using home equity debt for personal expenses like credit card payoff or vacation does not qualify for the deduction.
Example: Jennifer took out a $400,000 mortgage in 2023 at 6.5% interest. In her first full year, she paid approximately $25,800 in mortgage interest. She also paid $9,000 in property taxes and $3,000 in state income taxes. Her total potential itemized deductions from homeownership alone reach $37,800—well above the $15,750 single filer standard deduction. Itemizing saves her money.
Medical Expense Deduction: When High Healthcare Costs Help Your Taxes
You can deduct medical and dental expenses that exceed 7.5% of your AGI if you itemize. This includes costs for diagnosis, treatment, and prevention of disease, as well as insurance premiums you pay out of pocket.
| Your AGI | 7.5% Threshold | Medical Expenses Must Exceed |
|---|---|---|
| $50,000 | $3,750 | $3,750 to start deducting |
| $75,000 | $5,625 | $5,625 to start deducting |
| $100,000 | $7,500 | $7,500 to start deducting |
| $150,000 | $11,250 | $11,250 to start deducting |
Qualifying medical expenses include:
- Doctor, dentist, and specialist visits
- Hospital stays and surgeries
- Prescription medications
- Health insurance premiums (if paid with after-tax dollars)
- Long-term care insurance premiums (subject to age-based limits)
- Medical equipment and supplies
- Transportation to medical appointments
- Hearing aids, glasses, and contacts
Example: Robert has an AGI of $75,000 and paid $11,000 in unreimbursed medical expenses due to a surgery. His 7.5% threshold is $5,625. He can deduct $5,375 ($11,000 – $5,625). Combined with his other itemized deductions, this may push him over the standard deduction threshold.
Charitable Contributions: Deducting Your Generosity
Cash donations to qualified charitable organizations are generally deductible up to 60% of your AGI. Donations of appreciated property (like stocks) are typically limited to 30% of AGI but allow you to avoid paying capital gains tax on the appreciation.
Starting in 2026, a new 0.5% AGI floor applies to charitable deductions for itemizers. This means only the portion of your charitable giving that exceeds 0.5% of your AGI is deductible. For someone with $100,000 AGI, the first $500 of charitable donations provides no deduction.
Good news for non-itemizers: Starting in 2026, taxpayers who take the standard deduction can deduct up to $1,000 ($2,000 for joint filers) of cash contributions to certain qualified organizations—a new above-the-line deduction.
| Donation Type | Deduction Limit (% of AGI) |
|---|---|
| Cash to public charities | 60% |
| Appreciated property to public charities | 30% |
| Cash to private foundations | 30% |
| Appreciated property to private foundations | 20% |
The “Bunching” Strategy: Maximizing Deductions Across Multiple Years
If your itemized deductions fall just below the standard deduction threshold, bunching allows you to concentrate multiple years of deductions into a single year. This creates one year where you itemize with a large deduction and other years where you take the standard deduction.
| Strategy | Deductions 2025 | Deductions 2026 | Two-Year Total |
|---|---|---|---|
| Without Bunching | $28,000 (take standard $31,500) | $28,000 (take standard $31,500) | $63,000 |
| With Bunching | $48,000 (itemize) | $18,000 (take standard $31,500) | $79,500 |
In this example, a married couple who bunches gains $16,500 more in total deductions over two years. In the 22% bracket, this saves approximately $3,630 in federal taxes.
How to bunch: Contribute two or three years’ worth of charitable donations to a donor-advised fund in a single year. You receive the full tax deduction in the contribution year, and the fund distributes the money to your chosen charities over time.
Three Real-World Scenarios: When Itemizing Does (and Doesn’t) Increase Your Refund
Scenario 1: The New Homeowner in a High-Tax State
Marcus and Lisa are married, filing jointly, and recently bought a home in New Jersey. Their 2025 deductible expenses:
| Expense | Amount |
|---|---|
| Mortgage interest | $22,000 |
| Property taxes | $14,000 |
| State income taxes | $8,000 |
| Charitable contributions | $3,000 |
| SALT subtotal | $22,000 (capped at $40,000) |
| Total Itemized Deductions | $47,000 |
Their standard deduction is $31,500. By itemizing, they deduct $15,500 more than the standard deduction. At the 24% marginal rate, this saves them $3,720 in federal taxes—increasing their refund significantly.
Scenario 2: The Renter with Modest Expenses
David is single, rents his apartment, and lives in Texas (no state income tax). His 2025 deductible expenses:
| Expense | Amount |
|---|---|
| Charitable contributions | $2,500 |
| Medical expenses (AGI: $60,000) | $6,000 |
| Less 7.5% AGI threshold | -$4,500 |
| Deductible medical | $1,500 |
| Total Itemized Deductions | $4,000 |
David’s standard deduction is $15,750. His itemized deductions total only $4,000. Taking the standard deduction saves him $11,750 more in deductions. Itemizing would reduce his refund.
Scenario 3: The Retiree with High Medical Expenses
Sandra is 68, single, retired, and had a major surgery in 2025. Her AGI is $45,000.
| Expense | Amount |
|---|---|
| Medicare premiums + supplemental insurance | $8,000 |
| Surgery and hospital costs | $12,000 |
| Prescriptions | $3,000 |
| Total medical expenses | $23,000 |
| Less 7.5% AGI threshold ($3,375) | -$3,375 |
| Deductible medical | $19,625 |
| Property taxes | $4,000 |
| Charitable contributions | $1,500 |
| Total Itemized Deductions | $25,125 |
Sandra’s standard deduction as a single filer 65+ is $17,750 (base $15,750 + $2,000 additional). She may also qualify for the new $6,000 senior bonus deduction, bringing her potential standard deduction to $23,750. Her itemized deductions of $25,125 slightly exceed this, making itemizing the better choice by approximately $1,375.
Mistakes to Avoid When Deciding Whether to Itemize
Mistake 1: Assuming a $30,000 Deduction Means $30,000 in Tax Savings
A tax deduction reduces your taxable income—it does not reduce your tax bill dollar-for-dollar. A $30,000 deduction for someone in the 22% bracket saves approximately $6,600 in taxes, not $30,000.
| Misconception | Reality |
|---|---|
| “$30,000 deduction = $30,000 less tax” | $30,000 × 22% bracket = $6,600 tax savings |
Mistake 2: Not Comparing Itemized Total to Standard Deduction
Many taxpayers itemize without checking whether their total exceeds the standard deduction. Always calculate both options before filing. Tax software does this automatically, but if filing by hand, you must compare.
Mistake 3: Confusing Tax Deductions with Tax Credits
Deductions reduce taxable income; credits reduce the actual tax owed. A $1,000 tax credit is worth significantly more than a $1,000 tax deduction. For someone in the 22% bracket, a $1,000 deduction saves $220, while a $1,000 credit saves the full $1,000.
Mistake 4: Paying Mortgage Interest Just for the Tax Deduction
Paying $10,000 in mortgage interest to save $2,200 in taxes (22% bracket) is not financially advantageous. You lose $7,800 net. Do not maintain a mortgage purely for the tax benefit.
Mistake 5: Missing Documentation Requirements
The IRS can disallow deductions without proper documentation. Keep receipts, cancelled checks, bank statements, and written acknowledgments from charities for donations over $250. For noncash contributions over $500, you must file Form 8283.
Do’s and Don’ts When Deciding Whether to Itemize
| Do’s | Why |
|---|---|
| Do track all potentially deductible expenses year-round | You cannot claim what you cannot document |
| Do calculate both options before filing | The larger deduction saves more money |
| Do consider bunching if you are close to the threshold | Concentrating deductions maximizes benefits |
| Do include your spouse’s itemized expenses if married | Joint filers combine deductions |
| Do claim the additional standard deduction if 65+ | Extra $1,600-$2,000 per qualifying person |
| Don’ts | Why |
|---|---|
| Don’t itemize if your total is below the standard deduction | You leave money on the table |
| Don’t assume homeownership automatically means itemizing | Higher standard deductions changed this math |
| Don’t include expenses reimbursed by insurance | Only unreimbursed amounts qualify |
| Don’t deduct state income taxes and sales taxes | You must choose one or the other |
| Don’t forget about the SALT cap on your taxes | Property + income/sales taxes limited to $40,000 |
Pros and Cons of Itemizing Deductions
| Pros | Cons |
|---|---|
| Can reduce taxable income more than standard deduction if expenses are high | Requires significantly more recordkeeping and documentation |
| Allows deduction of large medical expenses, mortgage interest, and charitable gifts | Tax filing becomes more complex and time-consuming |
| Higher-income filers in high-tax states can save thousands | Risk of IRS audit is higher for itemizers |
| Bunching strategies can optimize deductions over multiple years | Many deductions have caps, floors, or income phaseouts |
| Newer homeowners with high mortgage interest often benefit | Standard deduction is now so high that most filers cannot exceed it |
Special Rules That Can Affect Your Itemized Deduction Strategy
State Tax Refunds May Become Taxable Income
If you itemized deductions last year and claimed state income taxes, your state tax refund may be taxable as federal income this year. This is called the “tax benefit rule”—you received a tax benefit from deducting those taxes, so the IRS recaptures part of that benefit when you get money back.
Exception: If your state income taxes were capped at $10,000 (or $40,000 under the new rules) and you paid more than the cap, the refund is not taxable because you did not actually receive a tax benefit on the capped portion. If you took the standard deduction or deducted sales tax instead of income tax, your refund is not taxable.
Married Filing Separately: Both Spouses Must Use the Same Method
If you file married filing separately, both spouses must either itemize or both take the standard deduction. One spouse cannot itemize while the other takes the standard deduction.
Gambling Losses: New 90% Limitation in 2026
Prior to 2026, you could deduct gambling losses up to the amount of gambling winnings. Starting in 2026, the OBBBA limits the deduction to 90% of your gambling losses or 90% of gambling gains, whichever is less. Even if you break even, you will owe taxes on 10% of your winnings.
Casualty Losses: Now Include State-Declared Disasters
For 2018-2025, casualty loss deductions are limited to federally declared disasters. Starting in 2026, the OBBBA expands eligibility to include state-declared disasters. Each loss must still be reduced by $100, and total losses must exceed 10% of AGI.
How to Fill Out Schedule A (Step-by-Step)
Schedule A is a one-page form with six main sections. You report your itemized deductions here and transfer the total to Form 1040, line 12.
| Schedule A Section | What to Enter |
|---|---|
| Lines 1-4: Medical Expenses | Total unreimbursed medical/dental expenses, then subtract 7.5% of AGI |
| Lines 5a-5e: Taxes Paid | State income OR sales tax + property tax (subject to $40,000 SALT cap) |
| Lines 8a-8e: Interest Paid | Mortgage interest from Form 1098 + points + investment interest |
| Lines 11-14: Charitable Contributions | Cash donations + noncash donations (may need Form 8283) |
| Line 15: Casualty Losses | Losses from federally/state-declared disasters only |
| Line 16: Other Deductions | Gambling losses, impairment-related work expenses, estate tax on income |
| Line 17: Total | Sum of all sections—compare to standard deduction |
Line 5e (SALT cap): If your state and local taxes exceed $40,000, enter only $40,000. If your MAGI exceeds $500,000, calculate your reduced cap based on the phaseout rules.
Who Benefits Most from Itemizing in 2025-2026
The expanded SALT cap and permanent mortgage interest deduction mean itemizing is now worthwhile for more taxpayers than in recent years. Those most likely to benefit include:
| Taxpayer Profile | Why Itemizing May Help |
|---|---|
| Homeowners in high-tax states (CA, NY, NJ, CT) | Combined property + income taxes can now exceed standard deduction |
| High-income earners with MAGI under $500,000 | Full $40,000 SALT cap + mortgage interest + charitable |
| Those with major medical expenses | Surgery, chronic illness, or long-term care costs can exceed 7.5% AGI |
| Substantial charitable donors | Bunching strategies + 60% AGI limit for cash |
| Seniors with significant healthcare costs | Medicare premiums + out-of-pocket expenses |
| Victims of federally or state-declared disasters | Casualty loss deductions available |
FAQs
Does itemizing always increase my refund?
No. Itemizing increases your refund only if your total itemized deductions exceed your standard deduction amount. Otherwise, taking the standard deduction saves you more.
Can I switch between itemizing and standard deduction each year?
Yes. You can choose the more beneficial option each tax year. There is no requirement to be consistent from year to year.
Do I need receipts for all my itemized deductions?
Yes. The IRS may request documentation to verify your deductions. Keep records for at least three years after filing.
What happens if my itemized deductions equal my standard deduction?
Take the standard deduction. It requires less documentation and reduces audit risk. There is no tax difference when amounts are equal.
Can I deduct property taxes if I don’t itemize?
No. Property tax deductions are only available on Schedule A. Taking the standard deduction means you cannot claim property taxes.
Is mortgage interest deductible if I take the standard deduction?
No. Mortgage interest is an itemized deduction only. You cannot add it on top of the standard deduction.
Are medical expenses deductible for everyone?
No. Only unreimbursed medical expenses exceeding 7.5% of your AGI qualify, and only if you itemize your deductions.
Does the $40,000 SALT cap apply to everyone?
No. The cap phases down for taxpayers with MAGI over $500,000 and fully reverts to $10,000 for those with MAGI over $600,000.
Can I deduct charitable donations without itemizing?
Starting in 2026, yes. Non-itemizers can deduct up to $1,000 ($2,000 for joint filers) of cash charitable contributions as an above-the-line deduction.
Will my state tax refund be taxable if I itemize?
Possibly. If you deducted state income taxes and received a tax benefit, your refund may be taxable. If you deducted sales tax instead, the refund is not taxable.
Do gambling winnings count as income even if I don’t itemize?
Yes. You must report all gambling winnings as income regardless of whether you itemize. Losses can only offset winnings if you itemize.
Can married couples split—one itemizes, one takes standard?
No. If married filing separately, both spouses must use the same method. Both itemize or both take the standard deduction.
