The main 2026 paycheck changes are inflation-adjusted federal tax brackets, a larger standard deduction ($16,100 for single filers), a higher Social Security wage base of $184,500, and higher limits for 401(k) and HSA contributions. Several states also changed their income tax rates, and new federal deductions for tips, overtime, seniors and car-loan interest affect what you owe when you file.
Some of these changes show up automatically in your paycheck. Others only matter if you act, such as raising your 401(k) contribution or updating your W-4. Here's a rundown of what changed and how it plays out in real paychecks.
Federal income tax: new brackets and standard deduction
The IRS adjusts the brackets and standard deduction each year for inflation. For 2026, the standard deduction is:
| Filing status | 2026 standard deduction |
|---|---|
| Single | $16,100 |
| Married filing jointly | $32,200 |
| Married filing separately | $16,100 |
| Head of household | $24,150 |
The 2026 brackets for a single filer are 10% up to $12,400 of taxable income, 12% up to $50,400, 22% up to $105,700, 24% up to $201,775, 32% up to $256,225, 35% up to $640,600 and 37% above that. Our federal income tax brackets guide lists every filing status.
Employers build these figures into payroll through IRS Publication 15-T, so you don't need to do anything for this part to apply. Your federal withholding updates on its own.
Example: a $65,000 salary in Ohio
For a single filer in Ohio earning $65,000, paid biweekly, the PaycheckHubs paycheck calculator estimates:
| Per biweekly paycheck | Amount |
|---|---|
| Gross pay | $2,500.00 |
| Federal income tax | $216.15 |
| Social Security | $155.00 |
| Medicare | $36.25 |
| Ohio income tax (estimate) | $38.92 |
| Net pay before local tax | $2,053.68 |
Ohio moved to a single 2.75% rate for 2026 on income above $26,050, with no state tax below that. Most Ohio cities also levy a municipal income tax, which isn't included above; enter your city's rate in the Ohio paycheck calculator to include it.
Social Security and Medicare
The FICA rates didn't change: 6.2% for Social Security and 1.45% for Medicare, with employers paying a matching share. What changed is the Social Security wage base, which rose to $184,500 for 2026. Once your wages for the year reach that amount, Social Security withholding stops until January.
For a single filer in Minnesota earning $190,000, paid biweekly, the calculator estimates about $440 per paycheck in Social Security. Because wages reach $184,500 near the end of the year, total Social Security for 2026 comes to about $11,439 rather than 6.2% of the full $190,000. The final paycheck of the year is larger as a result. See the Social Security wage base guide for more.
Medicare has no cap. The 0.9% Additional Medicare Tax still starts once an employer pays you more than $200,000 in a year.
Retirement and HSA limits went up
| Account | 2026 limit |
|---|---|
| 401(k), 403(b), 457 employee deferral | $24,500 |
| Catch-up, age 50 and older | $8,000 |
| Catch-up, ages 60 to 63 | $11,250 |
| IRA | $7,500 (plus $1,100 catch-up at 50+) |
| HSA, self-only coverage | $4,400 |
| HSA, family coverage | $8,750 |
These limits don't raise your contributions automatically. If you want to contribute the full $24,500 to a 401(k), that works out to about $942 per paycheck with 26 biweekly paydays, or about $1,021 with 24 semimonthly paydays. You'll need to update your election with your plan.
Example: pre-tax deductions for a head of household in North Carolina
A head of household filer in North Carolina earning $95,000, paid semimonthly, contributes 8% to a traditional 401(k) and $150 per paycheck to an HSA. The calculator estimates:
- Gross pay: $3,958.33 per paycheck
- Pre-tax 401(k) and HSA: $466.67
- Federal income tax: $283.50
- Social Security and Medicare: $291.34
- North Carolina income tax at the flat 3.99% rate: $118.12
- Net pay: $2,798.70
Over the year that's $7,600 to the 401(k) and $3,600 to the HSA, both under the 2026 limits. The HSA contribution here also lowers Social Security and Medicare, because payroll HSA contributions through a cafeteria plan aren't subject to FICA.

New federal deductions claimed on your return
Federal legislation passed in 2025 added deductions for qualified tips, qualified overtime pay, seniors, and interest on some car loans. These are claimed on your tax return. They generally don't change standard paycheck withholding, so your pay stub may look the same even if you qualify.
Each one has eligibility rules and limits that the IRS explains on its page about the new provisions. Our article on the new tips and overtime deductions covers how they interact with your paycheck.
State income tax changes for 2026
Several states lowered or restructured their income taxes for 2026, based on Tax Foundation data:
- North Carolina: flat rate of 3.99%, continuing a schedule of rate cuts.
- Georgia: flat rate of 5.19%, as the state keeps lowering it each year.
- Ohio: a single 2.75% rate on income above $26,050.
- New York: lower rates on its lower and middle brackets, with rates now from 3.9% to 10.9%.
- Minnesota: paid family and medical leave premiums begin in 2026, a new payroll deduction for many workers.
The nine states with no wage tax, including Texas and Tennessee, still don't tax wages. Connecticut and Utah have income-based phase-outs, so their calculators show estimates and explain what isn't modeled. See every state in the state calculator directory.
What to do about the 2026 paycheck changes
- Check your first few 2026 pay stubs. Compare federal withholding, Social Security and state tax with last year's.
- Update retirement and HSA elections if you want to use the higher limits.
- Review your W-4 if your family, job or income changed. The IRS Tax Withholding Estimator uses your current pay stub.
- Run your numbers in the paycheck calculator to see your estimated 2026 take-home pay.
Frequently Asked Questions
Why did my take-home pay change in January 2026?
New federal brackets and standard deductions, state rate changes, new benefit elections and a reset of the Social Security wage base all take effect at the start of the year. Higher earners often see smaller January paychecks because Social Security withholding starts again.
Do I need a new W-4 for 2026?
Not necessarily. A W-4 doesn't expire, and the 2026 tax tables apply automatically. Submit a new one if your situation changed or your withholding is off.
What is the Social Security wage base for 2026?
It's $184,500. Wages above that amount aren't subject to the 6.2% Social Security tax for the rest of the year.
How much can I put in my 401(k) in 2026?
Up to $24,500 in employee deferrals, plus an $8,000 catch-up if you're 50 or older, or $11,250 if you're 60 to 63.
