Standard Deduction 2026: How Much It Is, Who Gets It, and Why It Changed

The 2026 Standard Deduction Amounts

Let's start with the numbers. These come from IRS Revenue Procedure 2025-19, which sets the inflation-adjusted tax parameters for the 2026 tax year.

If you're 65 or older, blind, or both — you get extra. The additional standard deduction for 2026 is $1,950 for single and head of household filers, or $1,550 per qualifying spouse for married filers. So a married couple both over 65 filing jointly would get $30,000 + $1,550 + $1,550 = $33,100.

These numbers aren't dramatic year-over-year. The rounding at the $50 level means the small CPI-based adjustments didn't push the amounts into the next bracket. But the real story isn't the 2025-to-2026 change — it's what didn't happen.

The TCJA Cliff That Almost Was

Here's the context most people miss. Before the Tax Cuts and Jobs Act of 2017, the standard deduction for a single filer was $6,350. The TCJA nearly doubled it to $12,000 starting in 2018, and it's been inflation-adjusted every year since — climbing to $12,200, then $12,400, $12,550, $12,950, $13,850, $14,600, and eventually $15,000 for 2025.

But the TCJA was written with an expiration date: December 31, 2025.

Without new legislation, the standard deduction would have reverted to pre-TCJA levels for the 2026 tax year. That means roughly $8,300 for single filers — the old $6,350 base, adjusted for eight years of inflation. Married filing jointly would have dropped to about $16,600. That's a cut of nearly $7,000 for single filers and $13,400 for couples.

That didn't happen. The One Big Beautiful Bill Act — signed in early 2026 — preserved the TCJA's higher standard deduction levels and made them permanent. So the $15,000 / $30,000 / $22,500 numbers you see above are the continuation of the TCJA regime, not a reversion to the old system.

If you're wondering why your tax bill didn't spike this year — that's why.

What the Standard Deduction Actually Does to Your Paycheck

The standard deduction reduces your taxable income. Not your tax bill directly — your taxable income. That distinction matters because the tax savings depend on which bracket you're in.

Let's run real numbers for a single filer in 2026 using the standard deduction. These assume no other deductions or credits — just federal income tax and FICA.

The standard deduction saves every single filer at least $1,500 in federal tax (that's the 10% bracket floor applied to $15,000). At higher incomes, the savings climb because the top slice of that $15,000 deduction is coming out of a higher marginal bracket. A single filer earning $150,000 saves roughly $3,450 from the standard deduction alone — because a chunk of that deduction offsets income that would otherwise be taxed at 22% and 24%.

Standard Deduction vs. Itemizing: The 2026 Math

About 88% of taxpayers take the standard deduction. That number has held steady since the TCJA doubled the standard deduction in 2018 — before that, roughly 30% itemized.

Why don't more people itemize? Because $15,000 (single) or $30,000 (married) is a high bar to clear. To beat the standard deduction, your combined itemized deductions need to exceed those thresholds. Otherwise you're leaving money on the table.

The three big itemized deductions are:

• State and local taxes (SALT) — property tax, state income tax, or state sales tax. Capped at $10,000 under the original TCJA. The OBBB Act raised this to $40,000 for married filers ($20,000 single) with phaseouts for high incomes.
• Mortgage interest — deductible on up to $750,000 of acquisition debt. If you have a big mortgage in a high-cost area, this alone could be $15,000–$25,000 per year.
• Charitable contributions — cash donations up to 60% of AGI, plus fair market value of donated property.

Here's where 2026 gets interesting. The SALT cap increase under the OBBB Act means that taxpayers in high-tax states — New York, California, New Jersey, Connecticut, Illinois — can now deduct significantly more in state and local taxes than they could under the old $10,000 cap. A married couple in New Jersey paying $18,000 in property tax and $12,000 in state income tax was capped at $10,000 under the old rules. Under the new $40,000 cap, they can deduct the full $30,000.

Add a $20,000 mortgage interest deduction and $5,000 in charitable giving to that $30,000 SALT, and you're at $55,000 in itemized deductions. That crushes the $30,000 standard deduction. For married filers in expensive, high-tax states with large mortgages — itemizing is back on the table in a way it hasn't been since 2017.

For everyone else? The standard deduction almost certainly wins. If you're a renter in a no-income-tax state with modest charitable giving, you won't come close to $15,000 in itemized deductions. Don't overthink it — take the standard deduction and move on.

Who Can't Take the Standard Deduction

A few groups are excluded by law:

• Married filing separately when one spouse itemizes — if your spouse itemizes, you must too. Even if your itemized deductions are $400. This is one of the least-known quirks in the tax code and it bites people every year.
• Nonresident aliens — if you're filing as a nonresident alien (Form 1040-NR), you generally can't claim the standard deduction.
• Short tax years due to accounting period changes — rare, mostly affects businesses.
• Dependents — if you can be claimed as a dependent on someone else's return, your standard deduction is limited to the greater of $1,300 or your earned income plus $450, up to the normal standard deduction amount.

That dependent rule is the one that catches college students off guard. If your parents claim you, your standard deduction on your own return might be just $1,300 — not the full $15,000. Any unearned income (interest, investments) above that gets taxed at your rate.

The SALT Cap Change: Why It Matters Now

Let's be real: the $10,000 SALT cap was the most complained-about provision in the entire TCJA. Taxpayers in high-tax states — particularly New York, New Jersey, California, Connecticut, and Illinois — saw their federal tax bills jump because they could no longer deduct the full amount of their state and local taxes.

The One Big Beautiful Bill Act raised the SALT cap to $40,000 for married filers ($20,000 for single filers), with a phaseout beginning at $400,000 of modified AGI. That's a massive change. It means a married couple paying $35,000 in combined state income and property taxes can now deduct the full amount — whereas under the old cap, they lost $25,000 of that deduction entirely.

This directly affects the standard deduction vs. itemizing calculation. More taxpayers in high-tax states will now find that their itemized deductions exceed the standard deduction. If you live in a state with income tax above 5% and own property, it's worth running the numbers again. The math that pushed you to the standard deduction in 2019 may not hold in 2026.

How the Standard Deduction Has Changed Over Time

Some perspective on where we've been:

The 2017-to-2018 jump stands out. Going from $6,350 to $12,000 — an increase of $5,650 overnight — is the kind of change that reshapes filing behavior. And it did. The percentage of filers who itemize dropped from roughly 30% to about 12% in a single year. The TCJA effectively made the standard deduction the default for all but the wealthiest or most-indebted taxpayers.

The Tradeoff Nobody Talks About

When the TCJA doubled the standard deduction, it also eliminated personal exemptions. Before 2018, you could claim a $4,050 personal exemption for yourself, your spouse, and each dependent — on top of whatever deduction you took. A married couple with two kids got $4,050 x 4 = $16,200 in personal exemptions, plus a $12,700 standard deduction, for $28,900 total.

Under the TCJA — and now under the OBBB Act — personal exemptions are zero. You get $30,000 in standard deduction for that same married couple, but no personal exemptions. That's $30,000 vs. the old $28,900. Slightly better for a couple with no kids. Worse for large families.

The expanded Child Tax Credit partially offsets this for families with children, but the point remains: the "doubled standard deduction" headline obscures the fact that personal exemptions disappeared simultaneously. You didn't get twice the deduction for free — you traded one benefit for another.

What This Means for Your 2026 Return

If you're like most filers, the standard deduction is automatic. Your employer withholds based on it, your return claims it, done. No receipts needed, no Schedule A, no tracking charitable donations in a spreadsheet.

But if any of these apply to you, spend 15 minutes checking whether itemizing saves you money:

• You live in a state with income tax above 5% and own a home with property taxes above $8,000
• You have a mortgage balance above $300,000 at current interest rates
• You make significant charitable contributions — especially appreciated stock donations
• You had large unreimbursed medical expenses exceeding 7.5% of AGI

If none of those sound like you, take the standard deduction. Don't second-guess it. The $15,000 (or $30,000 for couples) is almost certainly more than you'd get by itemizing.
