Key Facts
- Federal level: Federal payroll taxes generally include federal income-tax withholding, Social Security and Medicare taxes under FICA, and federal unemployment tax under FUTA.
- Federal level: In 2026, the ordinary Social Security rate is 6.2% for the employee and 6.2% for the employer, while the ordinary Medicare rate is 1.45% for each.
- Federal level: Employers withhold the employee FICA share and generally pay a matching employer share; FUTA ordinarily comes only from employer funds.
- Federal level: Additional Medicare Tax is withheld at 0.9% after an employer pays an employee more than $200,000 in Medicare wages during a calendar year, without an employer match.
- Federal level: Most employers report income-tax withholding and FICA on Form 941 and report FUTA separately on Form 940.
- Federal level: Worker classification matters because businesses generally handle payroll withholding for employees, while independent contractors generally handle their own self-employment tax.
What federal payroll taxes include
“Federal payroll taxes” is an umbrella term rather than the name of one tax. For a typical private employer, the main components are federal income tax withheld from employee pay, Social Security and Medicare taxes imposed under the Federal Insurance Contributions Act, and federal unemployment tax imposed under FUTA.
These amounts do not all work the same way. Federal income-tax withholding is an employee income-tax prepayment. FICA has employee and employer components, while FUTA is generally an employer-funded tax reported separately from withholding and FICA.
Federal income-tax withholding follows the employee’s information
An employer generally withholds federal income tax from wages using the employee’s Form W-4, the applicable payroll period, and the methods in IRS Publication 15-T. The amount withheld is credited toward the employee’s federal income-tax liability rather than becoming a separate employer tax.
A change in wages, payroll frequency, Form W-4 entries, or certain supplemental-wage rules can change withholding. Withholding and final income-tax liability are not necessarily equal, which is why a return can show either tax due or a refund.
FICA combines Social Security and Medicare taxes
Section 3101 imposes the employee FICA taxes. The ordinary employee rate is 6.2% for Social Security and 1.45% for Medicare. Section 3111 imposes matching ordinary rates on employers.
Social Security tax applies only up to an annually adjusted wage base. For 2026, the IRS identifies that base as $184,500. Medicare tax has no comparable wage-base ceiling, so covered Medicare wages remain subject to the ordinary Medicare rate after Social Security withholding stops.
Additional Medicare Tax is different from the ordinary matching structure. An employer begins withholding the additional 0.9% when wages paid to one employee exceed $200,000 during the calendar year, without regard to that employee’s filing status, and the employer does not match it.
FUTA finances the federal-state unemployment system
Section 3301 imposes a 6% federal unemployment tax on wages within the statutory FUTA wage base. Credits connected to state unemployment contributions can reduce the effective federal rate when the governing requirements are met.
Employees do not have FUTA withheld from their pay. Employers ordinarily compute and report FUTA on Form 940, separate from Form 941 reporting for withheld income tax and FICA.
Reporting and depositing are separate duties
Most employers use Form 941 each quarter to report wages, federal income-tax withholding, Social Security tax, Medicare tax, and Additional Medicare Tax. Some eligible small employers use Form 944 when the IRS authorizes annual filing, while agricultural and household employment can involve different returns.
A return reports the liability; a federal tax deposit transfers money on the required schedule. Deposit frequency depends on the employer’s lookback-period liability and special next-day rules can apply after a sufficiently large accumulated liability.
Federal tax deposits generally must be made electronically. The IRS lists the Electronic Federal Tax Payment System and other approved electronic methods, but using a payroll provider does not eliminate the employer’s underlying federal responsibility.
Employee status controls the payroll-tax framework
Federal employment-tax treatment depends on whether a worker is an employee under the applicable common-law and statutory rules. A contract label alone does not control when the actual relationship shows the business has the relevant right to direct and control the work.
Businesses generally withhold income tax and employee FICA from employee wages, pay employer FICA, and may owe FUTA. Payments to a true independent contractor are generally not subject to those payroll withholdings; the worker instead may owe self-employment and estimated taxes.
The distinction also affects information reporting. Employees ordinarily receive Form W-2, while qualifying nonemployee compensation is generally reported on Form 1099-NEC; the related overview of 1099 worker taxes explains the nonemployee side.
A simplified payroll example
Suppose an employee receives $2,000 of covered regular wages before reaching the Social Security wage base. At ordinary 2026 rates, the employee Social Security withholding would be $124 and ordinary Medicare withholding would be $29. The employer would ordinarily owe matching amounts, apart from federal income-tax withholding and any FUTA liability.
This simplified calculation does not address pretax benefits, tip rules, sick pay, household or agricultural employment, railroad employment, territorial rules, or another statutory exception. Those details can change which payments count as wages and which return applies.
Late deposits and unpaid trust-fund taxes have distinct consequences
Amounts withheld from employee wages are commonly called trust-fund taxes because the employer holds them for the United States until deposit. Federal law can impose deposit penalties, return penalties, interest, and personal trust-fund recovery liability when responsible persons willfully fail to collect, account for, or pay over covered taxes.
Payroll deposit failures and individual estimated-tax underpayments belong to different penalty frameworks and should not be treated as the same issue.
Federal rules are only one payroll layer
State unemployment insurance, state or local income-tax withholding, paid-leave contributions, workers’ compensation, and wage-law deductions may add separate obligations. A federal payroll calculation does not establish compliance with those state and local systems.
Payroll records therefore need to distinguish gross wages, taxable wages for each tax, employee withholding, employer tax, deposits, returns, and corrections. That separation makes it possible to reconcile Forms 941 and 940 with Forms W-2 and the employer’s deposit history.
