Standard vs Itemized Deduction: Which Saves You More?

For 2026, the standard deduction is $14,600 for single filers and $29,200 for married filing jointly. You should only itemize if your total deductible expenses — mortgage interest, state and local taxes (capped at $10,000), charitable contributions, and medical expenses above 7.5% of AGI — exceed those amounts. For most filers earning under $200,000, the standard deduction wins. Roughly 90% of taxpayers take the standard deduction, and that percentage has remained steady since the 2017 Tax Cuts and Jobs Act nearly doubled it.

What the Standard Deduction Does

The standard deduction is a flat amount subtracted from your gross income before tax brackets apply. It requires no receipts, no tracking, no documentation beyond checking a box on your return. For a single filer earning $75,000, the $14,600 standard deduction reduces taxable income to $60,400. That reduction saves approximately $3,212 in federal tax at the 22% marginal rate on the deducted amount.

The standard deduction adjusts annually for inflation. In 2017, before tax reform, it was $6,350 for single filers — less than half the current amount. The near-doubling eliminated the itemization advantage for millions of taxpayers whose deductions fell between the old and new standard amounts.

Additional standard deduction amounts apply for age and blindness. Taxpayers 65 or older get an extra $1,550 (single/head of household) or $1,250 (married). A single filer over 65 gets a $16,150 standard deduction. These additions stack — a blind taxpayer over 65 filing single gets $17,700 total.

What You Can Itemize

Itemized deductions fall into several categories, each with specific rules and limitations that make the calculation less straightforward than most people assume.

Mortgage interest is deductible on loans up to $750,000 for homes purchased after December 15, 2017. On a $400,000 mortgage at 6.5%, first-year interest is approximately $25,800 — a significant deduction that by itself exceeds the single standard deduction. However, as the loan ages and more payments go toward principal, interest decreases. By year ten of the same loan, annual interest drops to about $20,500. By year twenty, it is roughly $11,800 — below the standard deduction threshold on its own.

State and local taxes (SALT) include state income tax or sales tax (you choose one, not both) plus property tax. The combined SALT deduction is capped at $10,000 regardless of filing status. A homeowner in New Jersey paying $12,000 in property tax and $5,000 in state income tax has $17,000 in SALT expenses but can only deduct $10,000. This cap is the single biggest reason many homeowners in high-tax states switched to the standard deduction after 2017.

Charitable contributions are deductible if you itemize, up to 60% of AGI for cash donations to qualifying organizations. Non-cash donations (clothing, furniture, vehicles) are deductible at fair market value. Contributions over $250 require written acknowledgment from the organization. Stock donations of appreciated securities let you deduct the full market value without paying capital gains tax — one of the most tax-efficient ways to give.

Medical and dental expenses are deductible only to the extent they exceed 7.5% of your AGI. If your AGI is $80,000, only medical expenses above $6,000 count. A $10,000 medical bill yields a $4,000 deduction. This threshold makes the medical deduction useful only in years with extraordinary healthcare costs — major surgery, dental reconstruction, fertility treatments, or ongoing expensive prescriptions.

When Itemizing Wins: The Breakeven Math

Itemizing beats the standard deduction when your total qualifying expenses exceed $14,600 (single) or $29,200 (married filing jointly). Here is how the numbers typically play out.

A single homeowner with a $350,000 mortgage at 6.5% pays about $22,600 in interest in year one, plus $5,000 in property tax and $3,000 in state income tax ($10,000 SALT cap applies, so $8,000 is usable), plus $1,500 in charitable giving. Total itemized deductions: approximately $32,100. Compared to the $14,600 standard deduction, itemizing saves an additional $17,500 in deductions, worth roughly $3,850 in tax savings at the 22% marginal rate.

A married couple renting an apartment with $6,000 in state taxes and $3,000 in charitable giving has $9,000 in itemizable expenses — far below the $29,200 standard deduction. They should take the standard deduction without question.

The gray zone exists for married homeowners with moderate mortgages. A couple with a $250,000 mortgage at 6% pays about $14,800 in interest, plus $6,000 property tax and $4,000 state income tax ($10,000 SALT cap), plus $2,000 charity. Total: $26,800. That is still $2,400 less than the $29,200 standard deduction. For this couple, paying off the mortgage faster actually saves them nothing in taxes since they would take the standard deduction anyway.

The Bunching Strategy

Bunching (also called "lumping") is a legitimate tax strategy where you concentrate two or more years of deductions into a single year to exceed the standard deduction threshold, then take the standard deduction in alternating years.

For example, a married couple normally donates $8,000 per year to charity and has $22,000 in other itemizable expenses ($30,000 total — barely exceeding the $29,200 standard deduction for a $800 benefit). Instead, they donate $16,000 every other year and zero in between. In the bunching year, itemized deductions are $38,000 — $8,800 above the standard deduction, saving roughly $2,112 at the 24% rate. In the off year, they take the $29,200 standard deduction. Over two years, they get $67,200 in total deductions versus $60,000 if they spread deductions evenly — an extra $7,200 in deductions worth approximately $1,728 in tax savings.

Donor-advised funds make bunching easier for charitable giving. You contribute a large lump sum to the fund (claiming the full deduction in that year), then distribute grants to your preferred charities over the following months or years. The upfront contribution gets the tax benefit immediately while the charitable giving continues on your preferred schedule.

Life Events That Change the Calculation

Buying a home is the most common trigger for switching from standard to itemized. But the home needs to carry enough mortgage interest to matter. On a $200,000 mortgage at 5%, first-year interest is only about $9,900 — not enough by itself to exceed the single standard deduction, even before SALT.

Divorce often forces the switch. A married couple taking the $29,200 joint standard deduction splits into two single filers each with a $14,600 threshold. If one spouse keeps the house, their mortgage interest plus SALT may push them into itemizing. The other spouse, now renting, almost certainly takes the standard deduction.

Large medical events — cancer treatment, major surgery, long-term care — can make itemizing worthwhile even for renters. If AGI is $70,000 and medical expenses reach $25,000, the deductible portion is $19,750 ($25,000 minus 7.5% of $70,000). Combined with even modest state tax and charitable deductions, this easily exceeds the standard deduction.

Retirement changes the math again. Once the mortgage is paid off, most retirees lose their biggest itemizable expense. But the additional standard deduction for age ($1,250 to $1,550 per person) partially compensates. Most retirees return to the standard deduction and stay there.

How to Decide Each Year

Run both calculations every year using our Income Tax Calculator. Tax situations change, and the right choice last year may not be right this year. Gather your mortgage interest statement (Form 1098), property tax records, state income tax paid, charitable receipts, and medical bills. Add them up. Compare to the standard deduction for your filing status. Take whichever is larger.

If the numbers are close — within $500 of each other — the standard deduction usually wins for its simplicity. Itemizing requires keeping records, increases audit risk slightly, and demands more time preparing your return or higher accountant fees. The $100 in extra tax savings from itemizing may not justify the effort if the margin is thin.
