Should You Itemize or Take the Standard Deduction in 2026? The Breakeven at Your Income

The 2026 standard deduction amounts you are comparing against

Before you can decide whether to itemize, you need the number you have to beat. These are finalized under IRS Rev. Proc. 2025-32, with the OBBBA making TCJA rates and deductions permanent.

The OBBBA senior bonus deduction ($6,000 per person age 65+) is an above-the-line deduction — it applies whether you itemize or take the standard deduction (OBBBA § 70103, tax years 2025–2028). It phases out starting at $75,000 single / $150,000 MFJ MAGI at a 6% rate, fully gone at $175,000 single / $250,000 MFJ. For seniors under the phase-out, this makes the standard deduction even harder to beat.

The four Schedule A categories that determine whether you itemize

Itemizing means adding up four buckets on Schedule A and comparing the total to the standard deduction for your filing status. If the total is higher, itemize. If it is lower, take the standard deduction. Here are the buckets and the rules that cap each one.

1. State and local taxes (SALT) — capped at $10,000

You can deduct the combined total of state income taxes (or state sales tax, if you elect) plus local property taxes — but only up to $10,000 ($5,000 if married filing separately). This cap was introduced by the 2017 TCJA and made permanent by the OBBBA. If your actual SALT bill is $25,000, you still deduct only $10,000 on Schedule A.

This cap is the single biggest reason most high-tax-state filers switched to the standard deduction after 2017. A New York single filer in the 5.85% state bracket paying $8,000 in property taxes might have $20,000+ in actual SALT — but only $10,000 counts on Schedule A.

2. Mortgage interest

You can deduct interest paid on up to $750,000 of mortgage acquisition indebtedness ($375,000 MFS). Mortgages originated before December 15, 2017 retain the prior $1,000,000 cap. Home equity loan interest is deductible only if the funds were used to buy, build, or substantially improve the home securing the loan.

At a 6.5% rate on a $500,000 mortgage, you pay roughly $32,000 in interest in year one. That alone nearly covers the $32,200 MFJ standard deduction. At a $300,000 mortgage, interest is closer to $19,000 — you need $12,200 more from SALT and charity to cross the MFJ threshold.

3. Charitable contributions

Cash contributions to qualifying public charities are deductible up to 60% of AGI. Appreciated long-term capital gains property is deductible at fair market value up to 30% of AGI. The pandemic-era $300/$600 above-the-line charitable deduction expired after 2021 — in 2026, charitable giving only reduces your tax if you itemize.

This is where charitable bunching becomes a lever. If you give $8,000 per year to charity, that is $16,000 over two years. Bunch it: give $16,000 in year one (via a donor-advised fund if you want to spread the actual grants), itemize that year, and take the standard deduction in year two. Two years of giving, but one year of itemizing — more total tax savings than giving $8,000 annually and never crossing the threshold.

4. Medical and dental expenses above 7.5% of AGI

Unreimbursed medical and dental expenses are deductible only to the extent they exceed 7.5% of your AGI. For a single filer with $80,000 AGI, the first $6,000 of medical expenses produces zero deduction. Only amounts above $6,000 count. This floor means medical expenses rarely push you over the threshold unless you had a major surgery, long-term care costs, or dental reconstruction in a single tax year.

Breakeven table: what it takes to beat the standard deduction

Here is the math at four common scenarios. Each row shows a filer’s Schedule A components and whether the total exceeds their standard deduction. The tax difference column shows how much more (or less) federal tax you owe by choosing the wrong method.

*Single age 68 standard deduction: $16,100 + $2,050 age-65 add-on = $18,150 (before the OBBBA senior bonus, which would add another $6,000 if MAGI is under $75,000). Medical net = $15,000 − 7.5% of $60,000 ($4,500 floor) = $10,500 deductible.

The second scenario is the instructive one. An MFJ couple with a $400,000 mortgage at ~6.5% barely crosses the $32,200 threshold — $300 of itemizing advantage translates to roughly $66 in tax savings at their 22% marginal rate. If that mortgage is a few years old and interest has dropped below $18,000, they flip back to the standard deduction. This is the knife-edge most homeowners sit on.

Decision tree: follow the branch that matches you

Branch 1: No mortgage, no unusually large medical bills

Take the standard deduction. Without mortgage interest, your Schedule A starts with at most $10,000 of SALT. You need $6,100 more (single) or $22,200 more (MFJ) from charity and medical alone to cross the threshold. Unless you are donating 15%+ of your income to charity or had a catastrophic medical year, the standard deduction wins — and it is not close.

Branch 2: Homeowner with a mortgage over $350,000

Run the Schedule A addition. At a 6.5% rate on a $500,000 mortgage, you generate roughly $32,000 in interest. Add the $10,000 SALT cap and you are at $42,000 before charity — well above the $32,200 MFJ standard deduction. At a $350,000 mortgage, interest is closer to $22,000; add $10,000 SALT and you are at $32,000 — just below the MFJ threshold. A few thousand dollars of charitable giving pushes you over.

The part most people miss: mortgage interest decreases every year as you pay down principal. A couple who itemized in year one of their mortgage may cross back under the standard deduction by year five or six. Recalculate annually — do not autopilot from last year’s return.

Branch 3: High-tax state, maxed SALT cap

Living in California (13.3% top rate), New York (10.9%), or New Jersey (10.75%) does not automatically mean you should itemize. The $10,000 SALT cap treats you the same as a filer in a no-income-tax state who pays $10,000 in property taxes alone. Your actual state tax burden might be $30,000 — but Schedule A caps it at $10,000 regardless.

A New York single filer earning $120,000 (5.85% state bracket, ~$7,000 state tax plus ~$8,000 property tax = $15,000 actual SALT) gets only $10,000 on Schedule A. They need $6,100 more from mortgage interest and charity to beat the $16,100 standard deduction. Without a mortgage, they take the standard deduction despite paying $15,000 in state and local taxes.

Branch 4: Big charitable giver (10%+ of income)

Itemize — or better yet, bunch. If you give $15,000+/year to charity and have $10,000 of SALT, your Schedule A starts at $25,000. Add even modest mortgage interest and you cross the MFJ threshold. If your giving is steady but falls just short, a donor-advised fund (DAF) bunching strategy puts two years of gifts into one tax year, crosses the threshold, and lets you take the standard deduction in the off year. Net result: more tax savings than giving the same annual amount every year.

Branch 5: Age 65+ with the OBBBA senior bonus

The math tilts harder toward the standard deduction. A single filer age 68 with MAGI under $75,000 gets: $16,100 standard deduction + $2,050 age-65 add-on + $6,000 OBBBA senior bonus = $24,150 effective standard deduction. That is higher than the head of household standard deduction for a younger filer. To beat $24,150 on Schedule A, a senior renter with no mortgage needs $14,150 beyond the $10,000 SALT cap from charity and medical alone — rare.

For an MFJ couple where both spouses are 65+ and MAGI is under $150,000: $32,200 + $3,300 (2 × $1,650 age add-on) + $12,000 (2 × $6,000 OBBBA bonus) = $47,500 effective standard deduction. Almost no combination of capped SALT, mortgage interest, and charity reaches $47,500. For seniors under the phase-out, itemizing is virtually dead.

Branch 6: Major medical year

A single year with $30,000+ in unreimbursed medical expenses can flip the itemize decision — but only the amount above 7.5% of AGI counts. On a $100,000 AGI, the floor is $7,500, so $30,000 of expenses produces a $22,500 medical deduction. Add $10,000 SALT and $2,000 charity and you are at $34,500 — well above the $16,100 single threshold. This is the one scenario where a filer with no mortgage can benefit from itemizing.

The catch: if you are over 65 and under the OBBBA phase-out, the effective standard deduction is $24,150 (single). Your $34,500 Schedule A total still wins, but by a narrower $10,350 — not the $18,400 it would be for a younger filer.

Worked example: the knife-edge MFJ homeowner

A Dallas couple, both 45, earns $180,000 combined. They bought a home in 2023 with a $420,000 mortgage at 6.75%. Their 2026 mortgage interest: roughly $27,200 (amortization table, year three). Texas has no state income tax, so their SALT is property taxes only: $7,800. They give $3,000/year to their church. No major medical expenses.

Schedule A total: $7,800 (SALT, under the $10,000 cap) + $27,200 (mortgage interest) + $3,000 (charity) = $38,000.

Standard deduction: $32,200 (MFJ).

Verdict: itemize. The $5,800 advantage at their 22% marginal rate saves them $1,276 in federal tax. But by year seven, the mortgage interest drops to ~$23,000. Their Schedule A falls to $33,800 — an advantage of only $1,600, or $352 in tax savings. By year nine, amortization pushes interest below $22,000 and the standard deduction wins. They should switch to standard at that point.

If the couple started bunching their charitable giving — $6,000 every other year instead of $3,000 annually — they could extend itemizing by an extra year or two. But at the margins, the effort of tracking Schedule A for $300 in savings is not always worth it.

Three myths that waste your time (or your money)

Myth 1: “High income means you should itemize”

Income does not determine the standard-vs-itemize decision — deductions do. A single software engineer earning $200,000 in a no-income-tax state (Texas, Florida, Washington), renting an apartment, giving $5,000 to charity, has a Schedule A total of roughly $5,000. The standard deduction ($16,100) wins by $11,100. High income without high deductible expenses means you take the standard deduction.

Myth 2: “The SALT cap does not affect me because I live in a low-tax state”

Property taxes alone can hit $10,000+ in many states, including Texas ($8,000–$15,000 on a median home in major metros), New Jersey ($9,000–$12,000), and Illinois ($6,000–$10,000). The SALT cap applies to total state and local taxes — property taxes count even when there is no state income tax.

Myth 3: “I should make extra charitable donations just to itemize”

Spending $1 to save 22 cents makes no economic sense. If your Schedule A total is $14,000 and the standard deduction is $16,100, donating an extra $2,100 to charity costs you $2,100 out of pocket to unlock the itemizing benefit. Your net tax savings from the marginal deduction — roughly $462 at the 22% rate — is far less than the $2,100 you spent. Give to charity because you want to. Never give solely to optimize your deduction.

Your next step depends on which branch matched you

No mortgage, no catastrophic medical year: stop here. Take the standard deduction. You are in the 90% majority.

Homeowner with a mortgage over $350K and in the first 5–7 years: add up your SALT (capped at $10,000), mortgage interest (check Form 1098), and charitable gifts. If the total exceeds your standard deduction by at least $2,000, itemize — the savings justify the effort. Recalculate next year.

Generous charitable giver but under the threshold: look into bunching via a donor-advised fund. One year on, one year off can save more than steady annual giving.

Age 65+ with MAGI under the OBBBA phase-out: your effective standard deduction is $24,150 (single) to $47,500 (MFJ, both 65+). Itemizing almost certainly loses. The one exception: a major medical event with $20,000+ in unreimbursed costs.

Right on the knife edge (Schedule A within $1,000 of the standard deduction): the tax savings at that margin is likely $200–$300. Take the standard deduction for simplicity unless you enjoy maintaining receipts.
