This hub answers 22 of the most common questions about payroll tax rates, withholding calculations, and wage base caps for 2026. Asure organizes these answers into five sections: Payroll Tax Fundamentals, Employer vs. Employee Payroll Tax Split, Wage Base Caps and Limits, Taxability Rules, and Year-Over-Year Changes, giving growth-stage payroll operators clear, source-backed guidance for running compliant payroll and forecasting employer costs.
Running payroll accurately means tracking three things at once: current rates, which wages count as taxable, and where wage base caps reset for the year. Miss any one of them and the effects show up quickly: an employee whose Social Security withholding never stops after crossing the cap, a FUTA payment calculated on the wrong wage base, or a paycheck that looks different in January for no reason you can immediately explain.
For growth-stage employers, this gets harder every year your business adds states, crosses new headcount thresholds, or gives raises that push more employees toward the Social Security cap. The answers below cover the mechanics behind FICA, FUTA, and SUTA rates, how caps work, what counts as taxable wages, and why withholding shifts at the start of each year, all grounded in current guidance from the IRS, the Social Security Administration, and state unemployment agencies.
Payroll Tax Fundamentals
Before splitting payroll tax by party or capping it by wage base, it helps to establish the basic numbers you are working with. Federal payroll tax in the United States is really a bundle of separate taxes: Social Security, Medicare, and federal unemployment tax, each with its own rate and its own rules about which wages count. Employers also owe state unemployment tax, which varies by state and by employer's own experience with unemployment claims. The questions below define the baseline rates and clarify what payroll tax is actually calculated on: gross wages before certain pre-tax deductions apply, not your employees' net take-home pay. Get these fundamentals right first, and the employer and employee splits, wage base caps, and taxability rules that follow will make a lot more sense.
What is the federal payroll tax rate?
The combined FICA tax rate is 15.3% of wages, split evenly between employer and employee at 7.65% each, according to the Social Security Administration's 2026 Social Security Changes Fact Sheet. That 7.65% breaks down as 6.2% for Social Security and 1.45% for Medicare per party. Social Security applies only up to the annual wage base; Medicare has no wage cap.
Is payroll tax based on gross or net pay?
Payroll tax is calculated on gross wages, not net take-home pay. However, gross wages are not the same as taxable wages. Under IRS rules, pre-tax deductions such as health insurance premiums under a Section 125 cafeteria plan reduce the wage base subject to FICA. Once those deductions are removed, payroll tax applies to what remains, before federal or state income tax withholding is subtracted.
What percentage is used to calculate payroll taxes?
Social Security tax is calculated at 6.2%, Medicare at 1.45%, and federal unemployment tax at 6.0% before credits, according to the Social Security Administration and IRS FUTA guidance. Employers and employees each pay the 6.2% and 1.45% rates; FUTA's 6.0% rate is owed by employers only, and most receive a credit that lowers it substantially.
How much is payroll tax in the USA overall?
The combined employer and employee FICA burden is 15.3% of wages, up to the Social Security wage base of $184,500 for 2026, per the Social Security Administration. Above that amount, only the 2.9% combined Medicare rate continues, since Social Security tax stops once wages cross the annual cap. Federal and state unemployment taxes add further employer-only cost on top of FICA.
Employer vs. Employee Payroll Tax Split
Employers and employees do not owe payroll tax in equal measure across every category. FICA, the tax funding Social Security and Medicare, is split evenly between the two parties. Federal unemployment tax and, in nearly every state, state unemployment tax are different. They fall on you as the employer alone and never appear as a line-item deduction on an employee's pay stub. Knowing which taxes are shared and which are yours alone matters for two audiences: payroll teams reconciling withholding against actual liability, and finance leaders forecasting the true cost of each new hire.
How much does an employer pay in payroll taxes?
Employers pay 7.65% of each employee's wages in FICA tax (6.2% Social Security plus 1.45% Medicare), matching the employee's share, per the Social Security Administration. On top of that, employers owe federal unemployment tax on the first $7,000 of wages, typically netting to $42 per employee per year after the standard state credit, per IRS guidance.
How much does an employee pay in payroll taxes?
Employees pay 7.65% of gross wages in FICA tax, 6.2% for Social Security and 1.45% for Medicare, per the Social Security Administration. Social Security withholding stops once wages exceed the annual wage base, while Medicare withholding continues on all wages with no ceiling. Employees have no federal or state unemployment tax obligation; both are employer-only taxes.
Do employers and employees pay the same payroll tax rate?
For FICA, yes, employers and employees each pay 7.65%, an equal split confirmed by the Social Security Administration. For federal and state unemployment tax, no, those are employer-only obligations that never appear on an employee's paycheck. Net FUTA typically runs 0.6% of the first $7,000 in wages after the standard state credit, per IRS guidance.
What is the federal employer payroll tax rate?
The federal employer payroll tax rate is roughly 8.25%, combining 7.65% FICA with 0.6% net federal unemployment tax after the standard state credit, per the Social Security Administration and IRS guidance. That combined figure applies only to each employee's first $7,000 of wages. After that threshold, only the 7.65% FICA share continues, up to the Social Security wage base.
How is SUTA calculated for employers?
State unemployment tax is calculated by multiplying an employer's state-assigned experience rate by the state's wage base for that employee. California's 2026 wage base, for example, is $7,000 per employee, the same as the federal FUTA floor, per the California Employment Development Department. Rates and wage bases vary by state, and AsureCentral tracks each state's current figures as part of payroll tax processing, eliminating manual tracking.
Wage Base Caps and Limits
Not every payroll tax applies to every dollar your employees earn. Wage base caps stop Social Security, federal unemployment tax, and state unemployment tax once an employee's wages for the year cross a set threshold. Medicare is the exception: it applies to every dollar of wages with no ceiling at all. These caps reset every January 1, which means an employee who stopped having Social Security withheld in November could see it start again on your first payroll run of the new year. Getting the caps and their crossover points right is one of the more error-prone parts of running payroll, especially if you have a handful of employees near or above the threshold. Which taxes are capped, at what amounts, and what to expect when an employee crosses a cap mid-year are covered in the questions below.
Which payroll taxes have a wage base cap?
Social Security, federal unemployment tax, and state unemployment tax all have wage base caps, meaning each stops applying once an employee's wages for the year cross a set dollar threshold, per the Social Security Administration and IRS guidance. Medicare has no cap and applies to all wages. The specific cap amount differs by tax and, for state unemployment tax, by state.
What is the Social Security wage base limit for 2026?
The Social Security wage base for 2026 is $184,500, up $8,400 from 2025's $176,100, according to the Social Security Administration's 2026 Social Security Changes Fact Sheet, announced in October 2025. Wages above that amount are exempt from the 6.2% Social Security tax for both employer and employee. The Medicare portion of FICA has no comparable cap.
Which payroll taxes do NOT have a cap?
Medicare is the payroll tax with no wage base cap: its 1.45% rate applies to every dollar of wages, per the Social Security Administration. A related tax, the Additional Medicare Tax, adds 0.9% once an employee's wages from a single employer exceed $200,000 in a calendar year, per IRS Tax Topic 560. Unlike base Medicare tax, the employer does not match this additional 0.9%.
What happens when an employee earns over the Social Security wage base?
Social Security withholding stops for the rest of the year once an employee's wages reach $184,500 in 2026, per the Social Security Administration. Medicare withholding continues on every dollar earned after that, with no ceiling. AsureCentral tracks each employee's year-to-date wages automatically and stops Social Security withholding at the correct point, without requiring a manual check of the running total each pay period.
Is there a limit on FUTA tax?
Yes, FUTA applies only to the first $7,000 of each employee's wages every year, regardless of how much the employee earns beyond that, per IRS guidance on the FUTA credit reduction. At the standard 6.0% rate minus the typical 5.4% state credit, the net federal unemployment tax liability is $42 per employee per year at most. A few states with outstanding federal unemployment loan balances may see a reduced credit in a given year, which raises their employers' net rate slightly.
Taxability Rules and What Counts as Taxable Wages
Rates and caps only matter once you know which wages they apply to, and that is where payroll tax gets confusing fast. Overtime pay counts as ordinary wages for tax purposes, but not every form of compensation does. Retirement contributions, health insurance premiums, and certain reimbursements each get different tax treatment depending on how they are structured, and mixing up which pre-tax deductions reduce FICA-taxable wages versus which only reduce federal income tax is one of the most common payroll errors growth-stage employers make. What counts as taxable wages for payroll tax purposes, and what does not, is clarified in the four questions below.
Is overtime pay subject to payroll tax?
Yes, overtime pay is treated as ordinary wages for payroll tax purposes. FICA applies to overtime at the same 7.65% employer and 7.65% employee split as regular wages, and overtime counts toward the Social Security wage base the same way regular pay does. There is no separate or reduced payroll tax rate for overtime hours.
Are 401(k) contributions subject to payroll tax (FICA)?
Yes, traditional 401(k) employee deferrals are still subject to FICA under IRS rules, even though they reduce federal taxable income. The deferred amount is included in Social Security and Medicare wages at the time it is earned. Employer matching contributions work differently: they are not treated as wages to the employee and are not subject to FICA at all.
What payments are NOT subject to payroll tax?
Several categories of compensation are excluded from payroll tax under IRS rules, most notably employer-paid health insurance premiums under a Section 125 cafeteria plan, contributions to a health savings account, and qualified moving expense reimbursements for active-duty military members moving under military orders, per IRS Topic No. 455. These exclusions apply to FICA wages specifically; some may still be treated differently for federal income tax purposes.
Do payroll deductions reduce taxable income for payroll tax purposes?
It depends on the deduction. Under IRS rules, Section 125 cafeteria plan deductions, such as employee health insurance premium contributions, reduce FICA-taxable wages, which lowers the base Social Security and Medicare tax is calculated on. Traditional 401(k) deferrals do not: they reduce federal (and often state) income tax withholding, but the deferred amount remains fully subject to FICA.
Year-Over-Year Changes and Withholding Fluctuations
Payroll tax rates themselves rarely change year to year, but the numbers around them do, and that is what catches payroll teams off guard every January. Wage base caps reset on January 1, which means employees who stopped having Social Security withheld late in the prior year suddenly see it reappear on their first paycheck of the new year. You also need to apply that year's updated Social Security wage base, FUTA parameters, and state unemployment figures correctly from your very first pay run. Growth-stage employers, especially those with employees near the Social Security cap or expanding into new states, feel this most.
Why are payroll taxes higher at the beginning of the year?
Payroll taxes are not actually higher in January. Withholding patterns just reset. Any employee who crossed the prior year's Social Security wage base and stopped having it withheld resumes full 6.2% withholding on January 1, since the wage base and the cap it creates apply on a calendar-year basis, per the Social Security Administration. Employee take-home pay can look smaller as a result, even though the rate itself has not changed.
Do payroll tax rates go up every year?
No, FICA rates are set by statute and have been stable since 1990, with one exception: a temporary 2011-2012 payroll tax holiday when the employee-side Social Security rate was reduced to 4.2%, per the Tax Policy Center's compilation of Social Security Administration historical data. What does change annually is the wage base, which the Social Security Administration adjusts each year based on national wage growth.
What is the current payroll tax rate for 2026?
For 2026, Social Security is 6.2% each for employer and employee, Medicare is 1.45% each, and FUTA is 6.0% gross (typically 0.6% net after the standard state credit), per the Social Security Administration and IRS guidance. State unemployment tax rates vary by state and by each employer's experience rating, so there is no single national SUTA percentage.
How do annual wage base changes affect employer cost forecasting?
The Social Security wage base rose $8,400 from 2025 to 2026, from $176,100 to $184,500, which raises the maximum possible Social Security tax by $520.80 for both employer and employee, per the Social Security Administration. If you have several employees earning above the prior year's cap, build that increase into your January cost forecasts, since it applies from the very first paycheck of the new year, not gradually.
Payroll Tax Rates at a Glance for 2026
The table below pulls the rates and wage bases from this hub into a single reference. Use it as a quick check before a pay run, not as a substitute for the primary agency source cited in each answer above, since state unemployment figures in particular vary by state and by employer.

|---|---|---|---|---|
| Social Security (OASDI) | 12.4% combined | 6.2% | 6.2% | $184,500 |
| Medicare | 2.9% combined | 1.45% | 1.45% | No cap |
| Additional Medicare Tax | 0.9% | Not applicable | 0.9% above $200,000 | No cap |
| FUTA | 6.0% gross, typically 0.6% net | 6.0% gross, typically 0.6% net | Not owed | $7,000 |
| SUTA | Varies by state | State-specific experience rate | Varies by state, mostly employer-only | Varies by state, for example $7,000 in California |
Getting Rates and Caps Right All Year
Payroll tax accuracy comes down to three moving parts: current rates, taxable wages, and wage base caps, and all three shift slightly every year. This hub covered 22 of the most common questions across payroll tax fundamentals, the employer and employee split, wage base caps, taxability rules, and year-over-year changes, grounded in guidance from the Social Security Administration, the IRS, and state agencies.
Asure supports growth-stage employers on these rates and caps in two ways. Employers who want to run payroll themselves can do so on AsureCentral, Asure's connected payroll and HR platform, which applies each year's updated wage bases and rates and stops Social Security withholding automatically once an employee crosses the annual cap, without you tracking it pay period by pay period. Employers who would rather hand the work off entirely can use AsureWorks, Asure's done-for-you payroll and HR managed service. AsureWorks is a PEO alternative, not a co-employment arrangement; the client remains the employer of record throughout, and Asure specialists apply updated federal and state payroll tax rates and wage base changes on the client's behalf every January, alongside running payroll and handling routine compliance administration. Whichever path fits your business, Asure keeps the rate and cap mechanics in this hub accurate without guesswork, reducing the time you spend re-checking withholding math so you can focus on running the business.
