Quick Answer In 2026, employers withhold 6.2% of each employee’s wages for Social Security tax up to a wage base of $184,500 and match that amount from their own funds. Once an employee crosses $184,500 in earnings, Social Security withholding stops — but Medicare tax continues on all wages with no ceiling. |
What Is Social Security Tax?
Social Security tax is the employer and employee contribution required under the Federal Insurance Contributions Act (FICA) to fund the Old-Age, Survivors, and Disability Insurance (OASDI) program. It provides retirement income, disability payments, and survivor benefits to eligible individuals.
Both employees and employers pay an equal share. The employer withholds the employee’s portion from each paycheck and remits both shares to the IRS on a set deposit schedule.
Social Security Tax Rates: 2024–2026
The tax rate has not changed in decades. What changes annually is the wage base limit — the earnings ceiling above which Social Security tax no longer applies.

Your Responsibilities as an Employer
- Withhold the employee’s 6.2%
Deduct from each paycheck every pay period. Stop once the employee’s year-to-date wages reach $184,500. Medicare withholding continues on all wages regardless. - Match with your own 6.2%
The employer’s portion comes from your own funds — never deducted from employee pay. Remit both shares together on your assigned IRS deposit schedule. - Follow your deposit schedule
Monthly depositors (lookback liability ≤$50K) deposit by the 15th of the following month. Semi-weekly depositors must deposit taxes by Wednesday for Wednesday–Friday paydays and by Friday for Saturday–Tuesday paydays. - File Form 941 quarterly
Report all wages, SS/Medicare withheld, and employer contributions. Due April 30, July 31, October 31, and January 31 each year.
Does the One Big Beautiful Bill Change Your Payroll Obligations? The One Big Beautiful Bill Act (OBBBA) is generating a lot of employee questions — but it does not change a single employer FICA obligation. Your 6.2% withholding, employer match, $184,500 wage base, and Form 941 filing schedule are all unchanged. What the law does do: it adds a new $6,000 income tax deduction for seniors aged 65+ (2025–2028), which — combined with the higher 2026 standard deduction — means roughly 88% of Social Security recipients will owe no federal income tax on their benefits. It also introduces employee-side deductions for qualified tips and overtime. These are all income tax deductions employees claim on their annual return, not payroll adjustments. Employees asking about these changes should update their Form W-4 if they want to adjust withholding. 📄 IRS — Full OBBBA Provisions · IRS — Senior Deduction Details |

Frequently Asked Questions
What is the Social Security wage base for 2026?
The wage base for 2026 is $184,500, up from $176,100 in 2025. Employers withhold and match 6.2% on wages up to this limit. Wages above it is exempt from Social Security tax for the rest of the calendar year.

What happens once an employee hits the wage base?
Social Security withholding stops automatically once wages reach $184,500. Medicare tax (1.45%) continues on all earnings — there is no Medicare wage cap. The Additional Medicare Tax (0.9%) begins above $200,000.
Is Social Security tax applied to bonuses?
Yes — bonuses are supplemental wages and subject to the 6.2% Social Security tax, up to the annual wage base. If an employee has already crossed $184,500 in regular wages before receiving a bonus, Social Security tax does not apply to that bonus.
What form do employers use to report Social Security taxes?
Most employers file IRS Form 941 quarterly. Very small employers with an annual payroll tax liability of $1,000 or less may file Form 944 annually, but only if the IRS notifies them to do so.
