The IRS raised 2026 tax brackets by roughly 2.7% under Rev. Proc. 2025-32, and the Social Security Administration delivered a 2.5% COLA effective January 2026 — two adjustments that together affect nearly every working and retired American’s bottom line. If you’re using an income tax calculator for 2026, the numbers below are the only official figures you should be entering.
2026 Federal Tax Brackets: Indexed 2.7% Above 2025 Levels
Every bracket threshold moved upward for 2026 under the Rev. Proc. 2025-32 inflation adjustments. The top marginal rate stays at 37%, but you reach it at a higher income than in 2025. The practical effect: a household with the same nominal income as last year pays slightly less in federal tax, because more of that income falls in lower brackets.
The standard deduction is the first number any income tax calculator applies. For 2026, single filers deduct $15,750 (up from $15,000 in 2025), married filing jointly deduct $31,500 (up from $30,000), and head of household filers deduct $23,625 (up from $22,500). These figures come directly from IRS Rev. Proc. 2025-32.
| Filing Status | 2025 Standard Deduction | 2026 Standard Deduction |
|---|---|---|
| Single | $15,000 | $15,750 |
| Married Filing Jointly | $30,000 | $31,500 |
| Head of Household | $22,500 | $23,625 |
The Child Tax Credit for the 2025 tax year — the return due April 15, 2026 — remains up to $2,200 per qualifying child. That figure applies to 2025 income, not 2026 income, so if you’re filing this spring, use $2,200. The 2026 credit amount will be confirmed when Congress acts or the IRS issues further guidance.
The $24,500 401(k) Limit and Who Gets the $11,250 Super Catch-Up
The 401(k) employee deferral limit for 2026 is $24,500, up from $23,500 in 2025. Workers age 50 and older can add a standard catch-up contribution of $8,000, bringing their total to $32,500. But the most significant change for 2026 is the SECURE 2.0-created “super catch-up” for workers ages 60 through 63: they can contribute an additional $11,250 instead of the standard $8,000 catch-up, for a total of $35,750.
The super catch-up does not apply at age 64 — it ends the calendar year you turn 64. If you turn 64 in 2026, you revert to the $8,000 standard catch-up for the remainder of the year. Confirm your plan accepts super catch-up contributions; not all recordkeepers had systems updated by January 1, 2026.
IRA contributions for 2026 are $7,500 for all filers, with a catch-up of $1,100 for those 50 and older — making the maximum IRA contribution $8,600. Note that the IRA catch-up is now indexed to inflation under SECURE 2.0; in 2025 it was $1,000. The $100 increase to $1,100 is the first adjustment since the provision took effect.
HSA Limits Hit $8,750 for Family Coverage in 2026
Health Savings Account limits for 2026 are $4,400 for self-only coverage and $8,750 for family coverage, both up from $4,300 and $8,550 in 2025. The $1,000 catch-up contribution for HSA holders age 55 and older is not indexed and remains $1,000. HSA contributions reduce your adjusted gross income dollar-for-dollar, making them one of the most efficient line items in any income tax calculation.
The Flexible Spending Account limit for 2026 is $3,400, up from $3,300 in 2025. Unlike HSAs, FSA funds are use-it-or-lose-it (with limited rollover provisions set by your employer plan). The IRS business mileage rate for 2026 is 70 cents per mile, relevant for self-employed filers and those with unreimbursed business travel deductible on Schedule C.
| Account / Limit | 2025 | 2026 |
|---|---|---|
| 401(k) employee deferral | $23,500 | $24,500 |
| 401(k) catch-up (50+) | $7,500 | $8,000 |
| 401(k) super catch-up (60–63) | $11,250 | $11,250 |
| IRA contribution | $7,000 | $7,500 |
| IRA catch-up (50+) | $1,000 | $1,100 |
| HSA self-only | $4,300 | $4,400 |
| HSA family | $8,550 | $8,750 |
| FSA | $3,300 | $3,400 |
Social Security 2026: 2.5% COLA, $176,100 Wage Base, and the $23,400 Earnings Test
The SSA’s 2.5% COLA took effect January 2026, lifting the average retired-worker benefit from roughly $1,927 to about $1,976 per month. The maximum monthly benefit for a worker claiming at full retirement age (67 for anyone born 1960 or later) is approximately $4,018. These are not projections — they are the official figures SSA announced in October 2025.
The Social Security wage base for 2026 is $176,100, up from $168,600 in 2025. Every dollar of wages up to that threshold is subject to the 6.2% employee Social Security tax (12.4% for self-employed). A worker earning exactly $176,100 pays $10,918.20 in Social Security tax in 2026; a worker earning $200,000 pays the same $10,918.20, because the tax stops at the wage base.
If you collect Social Security before reaching your full retirement age of 67 and continue working, the earnings test applies. In 2026, SSA withholds $1 for every $2 you earn above $23,400 per year. In the calendar year you reach FRA, the threshold rises to $62,160, and the withholding rate drops to $1 for every $3 above that limit. Withheld benefits are not lost permanently — SSA recalculates your benefit upward at FRA to credit the months it withheld payments.
SSI federal maximums for 2026 are $967 per month for an individual and $1,450 per month for a couple. These figures also reflect the 2.5% COLA and are confirmed at SSA.gov.
Medicare Part B at $206.50/Month in 2026 and the IRMAA Threshold at $106,000
The standard Medicare Part B premium for 2026 is $206.50 per month, up from $185.00 in 2025. The Part B deductible is $257 for 2026. Most Medicare beneficiaries pay the standard premium; higher earners pay more through the Income-Related Monthly Adjustment Amount (IRMAA).
You are 62 years old, earning $130,000 in W-2 wages in 2026, and your employer’s 401(k) plan accepts super catch-up contributions. You have $18,000 already deferred this year. You are deciding how to deploy the remaining $17,750 in potential contributions before December 31, 2026.
IRMAA surcharges begin at $106,000 of modified adjusted gross income for single filers and $212,000 for married filing jointly, based on your 2024 tax return (the most recent year SSA has on file when 2026 premiums are set). If your income dropped significantly in 2024 or 2025 due to retirement, divorce, or another life event, you can appeal the IRMAA determination using Medicare.gov Form SSA-44.
Estate and Gift Tax: $13.99 Million Exclusion and $19,000 Annual Gift Limit in 2026
The federal estate and gift tax lifetime exclusion for 2026 is $13.99 million per individual, up from $13.61 million in 2025. Married couples can shelter up to $27.98 million from federal estate tax through portability. This elevated exclusion is scheduled to sunset after December 31, 2025 under the Tax Cuts and Jobs Act unless Congress acts — but the IRS has confirmed the 2026 figure at $13.99 million, meaning the sunset did not take effect as originally written. Consult your estate attorney for current legislative status.
The annual gift tax exclusion for 2026 is $19,000 per recipient, up from $18,000 in 2025. You can give $19,000 to as many individuals as you choose without filing a gift tax return or touching your lifetime exclusion. A married couple can combine exclusions to give $38,000 per recipient per year through gift-splitting.
9 States With No Income Tax and the Federal $7.25 Minimum Wage in 2026
Nine states impose no state income tax on wages: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. Residents of these states calculate their total tax burden using only federal brackets — a meaningful advantage for high earners. New Hampshire taxes interest and dividend income for tax years prior to 2025; that tax has been fully phased out.
Confirm your 2025 W-2s, 1099s, and all income documents are received and match your records before filing — employers must mail W-2s by January 31, 2026 *
Verify your total 401(k) employee contributions did not exceed $23,500 for 2025 (or $31,000 if age 50+) to avoid a 6% excess contribution penalty *
Check whether you qualify for a filing extension by April 15, 2026 — note that an extension to file is NOT an extension to pay any taxes owed *
Review your 2025 federal tax bracket based on your filing status to ensure any estimated tax payments made during the year cover at least 90% of your 2025 liability or 100% of your 2024 liability to avoid underpayment penalties
Confirm your Traditional IRA or Roth IRA contributions for 2025 do not exceed $7,000 ($8,000 if age 50+) and verify your income falls within Roth eligibility limits
Gather documentation for any above-the-line deductions you plan to claim — such as student loan interest, HSA contributions, or self-employment expenses — to maximize your adjusted gross income reduction before choosing standard vs. itemized deductions
The federal minimum wage remains $7.25 per hour, unchanged since 2009. Several states raised their minimums effective January 1, 2026; workers in those states should use their state wage floor when calculating annual income for withholding purposes. State minimum wage changes affect the income side of any tax calculator, not the federal bracket structure itself.
Your 2026 Tax Calendar: April 15, Q1 Estimates, and October COLA Announcement
The IRS Tax Withholding Estimator at IRS.gov uses current-year bracket data and is updated each January. It is the most accurate free tool for estimating 2026 federal withholding, particularly after a life change — marriage, a new job, a Roth conversion, or the start of Social Security benefits. Run it after any event that changes your income or filing status, not just once at year-end.
SSA announces the 2027 COLA in October 2026, and the IRS will release 2027 inflation-adjusted bracket figures — the successor to Rev. Proc. 2025-32 — in the same window.
