The standard deduction is the single most widely claimed tax deduction in the United States — taken by roughly 90% of all taxpayers. For 2026 it moved for two SEPARATE reasons, not one: the OBBBA (One Big Beautiful Bill Act, signed July 2025) permanently reset the 2025 baseline above what the pre-OBBBA inflation schedule would have produced, and then the IRS’s routine annual inflation adjustment (Rev. Proc. 2025-32) applied on top of that higher baseline to produce the 2026 figures. Both moves point the same direction — up — but they’re legally distinct events, and only the second one repeats every year.
For the full 2026 table by filing status, the age-65/blind add-on breakdown, the OBBBA senior bonus rules, and how a dependent’s deduction is figured, see the 2026 standard deduction reference page. This article focuses on what changed and why, and what that means for the standard-vs-itemize decision.
What actually changed for 2026
Two things happened in sequence:
- OBBBA reset the 2025 baseline (one-time, now permanent). Before OBBBA, the 2025 standard deduction was on track to be a smaller, purely inflation-indexed figure. OBBBA §70102 raised that 2025 starting point directly and made the higher baseline permanent (no more TCJA-style sunset risk).
- Rev. Proc. 2025-32 applied the normal annual inflation adjustment for 2026. This is the same routine mechanism that has run every year since the Tax Cuts and Jobs Act took effect — it just now compounds on top of the OBBBA-raised 2025 number instead of the smaller pre-OBBBA figure.
The net effect: every filing status is higher in 2026 than in 2025, and higher than it would have been without OBBBA at all. The reference page above has the exact dollar table and year-over-year deltas for every filing status.
Additional standard deduction for age 65+ and blindness
Filers age 65+ or legally blind still receive the separate additional standard deduction on top of the base amount shown above — also inflation-adjusted for 2026. The full single/married breakdown (including when a couple filing jointly has two qualifying spouses) is on the 2026 standard deduction reference page; note that this permanent add-on is DIFFERENT from the new, temporary OBBBA senior bonus deduction — the reference page has a dedicated section walking through the distinction.
Why the Standard Deduction Matters
The standard deduction reduces your taxable income dollar-for-dollar. For a single filer earning $60,000 in wages:
- Without any deduction, taxable income = $60,000
- After the $16,100 standard deduction, taxable income = $43,900
- At the 12% marginal rate, that $16,100 deduction saves approximately $1,932 in federal tax
The actual savings depend on your marginal rate. The higher your bracket, the more valuable each additional dollar of deduction.
| Filing Status | 2026 Standard Deduction | Tax Savings at 12% | Tax Savings at 22% | Tax Savings at 24% |
|---|---|---|---|---|
| Single | $16,100 | $1,932 | $3,542 | $3,864 |
| Married Filing Jointly | $32,200 | $3,864 | $7,084 | $7,728 |
| Head of Household | $24,150 | $2,898 | $5,313 | $5,796 |
Standard Deduction vs. Itemizing in 2026
For most people, the standard deduction is the right choice — but if your qualifying expenses exceed the threshold, itemizing may save you more. Common itemized deductions include:
- State and local taxes (SALT): under OBBBA (2025+), capped at $40,000 per return ($20,000 MFS) in 2025, rising to $40,400 / $20,200 in 2026 (1% indexing under OBBBA §70120). Phases out above $500,000 MAGI ($250,000 MFS; $505,000 / $252,500 in 2026) toward a $10,000 floor. Pre-OBBBA 2018–2024 was $10,000 flat.
- Mortgage interest: on the first $750,000 of acquisition debt
- Charitable contributions: generally up to 60% of AGI for cash donations
- Medical expenses: the portion exceeding 7.5% of AGI
- Casualty and theft losses: only for federally declared disaster areas
The itemizing math for a single filer in 2026:
If your SALT is $8,000, mortgage interest is $6,500, and charitable giving is $2,000, your itemized total is $16,500 — only $400 more than the $16,100 standard deduction. The extra paperwork and record-keeping may not be worth the modest benefit.
For most middle-income single filers, itemizing is worthwhile only if mortgage interest alone is substantial, or if a combination of SALT, mortgage interest, and significant charitable giving clearly clears the bar.
Two eligibility edge cases worth knowing
Not everyone gets a choice: a married person filing separately whose spouse itemizes must also itemize, most nonresident aliens can’t take the standard deduction at all, and a short tax year (under 12 months, from an accounting-period change) forecloses it too. Separately, if you’re claimed as someone else’s dependent, a different greater-of calculation tied to your earned income applies instead of the usual filing-status number. The reference page walks through both rules with the exact current-year dollar amounts and worked examples, rather than repeating them here.
Practical Planning Tips for 2026
Bunch deductions in alternating years. If your itemizable expenses hover near the standard deduction threshold, consider concentrating deductions in even-numbered years and claiming the standard deduction in odd years (or vice versa). For example, making two years of charitable contributions in a single year can push you over the bar in that year while the standard deduction covers the other year.
Donor-Advised Funds (DAFs) for charitable bunching. Contributing a large lump sum to a DAF allows you to claim the full charitable deduction in the year of contribution, then distribute grants to charities over time.
Medical expense timing. If you have elective procedures or predictable medical costs that might breach the 7.5%-of-AGI threshold, grouping them in the same calendar year maximizes the deduction.
Review SALT impact. The OBBBA SALT cap for 2026 is $40,400 ($20,200 MFS) with the phaseout starting at MAGI above $505,000 ($252,500 MFS) and reverting toward a $10,000 floor. Ultra-high-income taxpayers in high-tax states still effectively hit the $10,000 floor and need significantly higher mortgage interest or charitable giving to exceed the standard deduction.
Key takeaway
The 2026 increase is two layered effects, not one: OBBBA’s permanent baseline reset plus this year’s routine inflation adjustment on top of it. Either way, it’s a straightforward benefit requiring no action on your part — you simply claim it on your return. If you currently itemize, it’s worth re-running the comparison to confirm your itemized total still clears the new, higher bar; see the 2026 standard deduction reference page for the exact numbers and the standard-vs-itemize calculators.
