Itemized Deductions: How to Maximize Your Tax Savings

Every April, millions of Americans face the same question without realizing how much money is at stake: should they list their actual expenses or simply accept a flat government amount? Itemized deductions, the specific qualifying expenses a taxpayer lists individually on Schedule A of Form 1040, are at the center of this decision. For 2026, the answer has changed for more people than most expect.

The One Big Beautiful Bill Act (OBBBA), signed into law in July 2025, rewired the deduction landscape in ways that are simultaneously more generous and more restrictive, depending on who is filing.

The state and local tax cap jumped from $10,000 to over $40,000, a new charitable deduction floor arrived, and a limitation on the tax benefit of deductions hit the highest earners. These are not minor tweaks.

This article breaks down how itemized deductions work in 2026, who benefits most, and how to strategize around the new rules. It also includes a critical clarification for self-employed taxpayers who may be approaching this decision incorrectly.

The Foundation: Standard Deduction vs. Itemized Deductions

Before evaluating any individual expense category, it helps to understand the core mechanic. Every taxpayer chooses between two paths: claim the standard deduction, a fixed dollar amount set by the IRS based on filing status, or itemize, listing each eligible expense separately on Schedule A and deducting the actual total.

The rule is straightforward: whichever path produces the larger deduction wins. However, calculating which path actually wins requires knowing the numbers for 2026.

For 2026, per the IRS official tax year 2026 inflation adjustments, the standard deduction figures are as follows:

Filing Status	2026 Standard Deduction
Single / Married Filing Separately	$16,100
Married Filing Jointly	$32,200
Head of Household	$24,150

These thresholds are the targets. A taxpayer’s Schedule A total must exceed them to make itemizing worthwhile. For most Americans (such as renters, residents of low-tax states, and those without large mortgage balances), the standard deduction still wins easily.

However, 2026’s legislative changes have shifted that calculation meaningfully for a segment of filers who have been defaulting to the standard deduction since 2018.

The SALT Deduction: The Biggest Shift in 2026

The state and local tax (SALT) deduction covers state income taxes (or sales taxes, whichever is greater), real estate taxes, and personal property taxes like value-based vehicle registration fees.

Since 2018, this deduction had been capped at $10,000, effectively neutralizing it for homeowners in states like California, New York, New Jersey, and Connecticut, where property taxes alone frequently exceeded that limit.

Under the OBBBA, the cap rose to $40,400 for 2026, with annual 1% increases running through 2029 before reverting to $10,000 in 2030. This change reactivates itemizing for a large segment of middle-class homeowners who had abandoned Schedule A years ago.

How the SALT Phase-Out Works for Higher Earners

The expanded cap does not apply uniformly at all income levels. Taxpayers whose modified adjusted gross income (MAGI) exceeds $505,000, or $252,500 for those married filing separately, face a phase-down of 30 cents for every dollar of MAGI above that threshold, with a hard floor of $10,000.

Consider a practical example: a single filer with a MAGI of $555,000 has income that exceeds the threshold by $50,000.

Thirty percent of this excess ($15,000) reduces their available cap to $25,400. The deduction is still substantial but not the full ceiling, and it effectively returns to $10,000 at approximately $640,000 MAGI.

For most middle-income homeowners in high-tax states, though, the full cap applies. A homeowner in New Jersey paying $14,000 in property taxes and $10,000 in state income taxes now has $24,000 in deductible SALT, more than double what the previous rules allowed. Combined with mortgage interest, this alone can push a single filer well past the $16,100 standard deduction threshold.

Mortgage Interest: Still the Anchor for Most Itemizers

For homeowners with significant loan balances, mortgage interest remains the most reliable contributor to itemizing. The rules here depend on when the loan originated.

Mortgages taken out after December 15, 2017 allow interest deductions on up to $750,000 of acquisition debt (loans used to buy, build, or substantially improve a primary or secondary home).

Older mortgages carry a higher $1,000,000 ceiling. A homeowner with a $600,000 mortgage at 6.5% generates roughly $38,000 in annual interest, which on its own exceeds the single filer standard deduction.

Additionally, mortgage insurance premiums return as a deductible item starting in tax year 2026, phasing out between $100,000 and $110,000 of AGI. This reinstated deduction can make a difference for buyers who put down less than 20% and carry private mortgage insurance.

Home equity loan interest, by contrast, remains deductible only when the borrowed funds were used to buy, build, or improve the home, not for personal expenses like paying off credit cards or vacations.

Medical Expenses, Charitable Contributions, and Casualty Losses

Medical and Dental Expenses

Medical and dental expenses are only deductible to the extent they exceed 7.5% of adjusted gross income. On a $100,000 AGI, the first $7,500 in medical costs produces no deduction; only the amount above that floor counts.

Qualifying expenses include doctor and dentist visits, prescription medications, health insurance premiums paid out-of-pocket, mental health treatment, hearing aids, vision care, and mileage driven to medical appointments.

Notably, this deduction rarely moves the needle for healthy working-age adults. It tends to matter most during years involving major surgery, serious illness, or significant ongoing care costs that push spending far above the AGI threshold.

Charitable Contributions: A New Floor in 2026

Starting with the 2026 tax year, the OBBBA introduced a 0.5% AGI floor on charitable contributions for itemizers. Only donations exceeding that floor count toward the deduction. For a taxpayer with $150,000 AGI, the first $750 in charitable giving produces no deduction. On $4,000 in total donations, only $3,250 is deductible.

This change rewards larger givers and creates an incentive to front-load charitable activity. Taxpayers who donate regularly should consider bunching two years of giving into a single tax year (itemizing in the donation year, then taking the standard deduction the following year).

Moreover, a donor-advised fund can facilitate this approach, allowing a large contribution in year one with grants to specific charities distributed over time.

Importantly, the pandemic-era above-the-line deduction for non-itemizers was replaced with a new permanent version under OBBBA, allowing non-itemizers to deduct up to $1,000 in cash charitable donations ($2,000 for married couples filing jointly). This is a separate provision and does not apply to property donations or contributions through donor-advised funds.

Casualty and Theft Losses

Since 2018, personal casualty and theft losses are only deductible when they stem from a federally declared disaster. Each qualifying loss is reduced by $100, and only the portion exceeding 10% of AGI is deductible.

This deduction rarely applies for most filers but can be significant for those affected by hurricanes, wildfires, or flooding in declared disaster areas.

Who Benefits Most from Itemizing in 2026

Three types of taxpayers stand out as the most likely to benefit from itemizing in 2026. Knowing whether you fit into one or more of these categories is the fastest way to determine whether running the Schedule A numbers is worth the effort.

• Homeowners in high-tax states, particularly those in California, New York, New Jersey, Connecticut, or Massachusetts, who pay significant property and state income taxes. With the SALT cap now at $40,400, many of these filers can itemize for the first time since 2018.
• Taxpayers with large mortgages, especially anyone carrying $500,000 or more in mortgage debt, generate substantial annual interest payments and have a strong case for Schedule A.
• Significant charitable givers who donate meaningfully each year can often exceed the standard deduction, especially when their contributions are combined with SALT and mortgage interest.
• Taxpayers with major medical events, as years involving serious surgery, hospitalization, or ongoing specialized care can generate deductible expenses above the 7.5% AGI floor.

Conversely, renters in low-tax states with modest incomes and average charitable giving will almost always find the standard deduction more advantageous. The key is running the actual numbers rather than assuming.

A Critical Clarification for Self-Employed Taxpayers

One of the most persistent and costly misunderstandings in the self-employed community is the idea that itemizing on Schedule A is how business expenses get deducted. It is not.

Business deductions like office supplies, professional development, vehicle use, and business software belong on Schedule C, not Schedule A. These are separate forms serving entirely separate purposes.

A freelance consultant who deducts $25,000 in business expenses on Schedule C can still take the standard deduction on their personal return. They can also itemize if their personal Schedule A expenses, such as SALT, mortgage interest, and charitable giving, exceed the standard deduction threshold. The two decisions are completely independent of each other.

Additionally, self-employed individuals who pay their own health insurance premiums typically claim that deduction on Schedule 1 as an above-the-line reduction, not on Schedule A. This approach is generally more beneficial because it reduces AGI before the standard vs. itemized calculation even begins.

Strategies to Get the Most from Schedule A

Approaching Schedule A strategically, rather than reactively, can produce meaningfully better outcomes. Several specific techniques apply directly to 2026 filers.

• Time property tax payments carefully. If a state or locality allows prepayment, doing so before December 31 pulls the deduction into the current tax year.
• Bunch charitable donations into alternating years, especially given the new 0.5% AGI floor. Concentrating two years of giving into one year produces a larger deduction.
• Track medical mileage and out-of-pocket costs throughout the year. Many taxpayers overlook travel to appointments, which qualifies at the IRS medical mileage rate.
• Request Form 1098 from your mortgage lender each January and verify the reported interest matches your payment records before filing.
• Compare both options explicitly before filing. Tax software calculates both paths, but reviewing the numbers manually builds awareness of which expenses are driving the outcome.

Furthermore, high earners in the 37% tax bracket face a new OBBBA limitation that reduces the tax benefit of itemized deductions.

This nuance warrants direct consultation with a tax professional before finalizing a filing strategy. PKF O’Connor Davies provides a detailed breakdown of how the OBBBA reshapes itemized deductions for top earners, including the mechanics of the new 2/37 limitation.

Final Thoughts on Making the Right Call

The shift introduced by the OBBBA makes 2026 a consequential year for itemized deductions, not because the concept changed, but because the numbers shifted enough to move many taxpayers across the threshold. Filers who have reflexively claimed the standard deduction for the past several years owe it to themselves to recalculate.

For self-employed individuals, the most important takeaway may simply be this: business deductions and personal deductions operate on parallel tracks, and maximizing one does not come at the expense of the other.

Taxes reward preparation and specificity. Keeping organized records throughout the year, such as mortgage statements, donation receipts, property tax bills, and medical invoices, is what separates a well-executed Schedule A from a missed opportunity.
