Payroll tax rates are the percentages used to calculate employment taxes on wages that are subject to those taxes. In the United States, they determine amounts withheld from employees and amounts employers pay for programs such as Social Security and Medicare. Some rates apply to wages only up to an annual limit while others apply to all covered wages or begin after a threshold is reached. Federal rates are set nationally, but unemployment insurance and certain other payroll-related obligations can vary by state or locality. A payroll tax rate is not the same as an income tax withholding rate or a worker’s total tax rate. The amount due depends on both the applicable rate and which wages are taxable under the specific rule.

Which Federal Payroll Tax Rates Apply?
For 2026, Social Security tax is 6.2% for the employee and 6.2% for the employer on each employee’s covered wages up to $184,500. Medicare tax is 1.45% for the employee and the same amount for the employer on all covered wages, with no annual wage limit. These taxes are commonly grouped as FICA. Below the Social Security wage limit, the standard employee share is 7.65% and the employer owes a separate 7.65%. The Social Security tax rate and wage cap are set federally and can change by year. The Social Security Administration publishes the annual taxable earnings limit.
Employers must also withhold an additional 0.9% Medicare tax from an employee’s Medicare wages above $200,000 paid by that employer during the calendar year. There is no employer match for this additional tax. The withholding threshold is not adjusted for filing status or income from another employer. An employee’s final liability is determined on the tax return and may depend on filing status and other income. The IRS explains the distinction between the employer’s withholding duty and the individual’s liability in its guidance on Additional Medicare Tax.
How Are Rates Applied to Wages?
The basic calculation is taxable wages multiplied by the rate that applies to those wages. The key is identifying the wage amount for each tax, rather than applying every rate to gross pay. A taxable wage base is the maximum amount of a worker’s wages subject to a particular tax during a specified period. Payroll records must track cumulative wages so a capped tax stops at the correct point. Other taxes may have no wage cap or may use a different definition of taxable pay.
For example, an employee receives $2,000 in wages during 2026 that are fully subject to FICA. The employee is below the Social Security wage limit and has not reached the Additional Medicare Tax withholding threshold. The employee’s Social Security withholding is $124 and Medicare withholding is $29. The employer separately owes $124 for Social Security and $29 for Medicare. This example covers FICA only. It does not include federal or state income tax withholding or unemployment taxes.
Taxable wages may differ from gross pay because particular payments or benefits can receive different treatment under tax rules. Payroll must apply the correct wage definition before multiplying by a rate. A correct percentage cannot make up for including wages that are excluded or omitting wages that are covered. This is why payroll processing involves both rate calculation and accurate wage classification.
How Do Unemployment Tax Rates Work?
Federal unemployment tax under FUTA is generally an employer-paid tax. For 2026, the standard rate is 6% on the first $7,000 of each employee’s FUTA-taxable wages. An eligible employer may generally claim a credit of up to 5.4% for qualifying state unemployment contributions. If the full credit applies, the effective federal rate is 0.6%, with a maximum federal tax of $42 per employee for the year. This federal tax is separate from FUTA reporting and payment requirements.
The full credit is not automatic in every circumstance. State contribution payment status and federal credit-reduction rules can affect the credit. Employers should check the applicable tax year rather than assume the lowest effective rate. State unemployment insurance is calculated separately. States set their own wage bases and rate systems, and an employer’s assigned rate may reflect its unemployment claims experience. The federal effective rate alone therefore does not show an employer’s full unemployment tax cost.
Why Do Rates Vary by Location?
There is no single state payroll tax rate that applies nationwide. States establish unemployment insurance rules and may also require contributions for programs such as disability insurance or paid leave. Some local jurisdictions impose additional obligations tied to employment or wages. Each tax must be considered on its own terms because its taxable wages and payer may differ from those of another tax. An employer should use its assigned rate and verify the wage base and coverage rules for the relevant jurisdiction.
Work location can matter when a worker is remote or moves during the year. The correct payroll setup may depend on where services are performed and on the applicable state rules. A rate notice for one state should not be carried over automatically to a different work location. Employers also need to identify which state unemployment system applies before calculating contributions. Applying the right percentage to the wrong jurisdiction can still produce an incorrect payment.
How Do Rates Affect Pay and Contingent Work?
Employee payroll tax withholding and employer payroll taxes are separate amounts. Employee withholding reduces the worker’s take-home pay. The employer’s share is an additional employment cost and is not a deduction from the employee’s wages. Federal income tax withholding is also separate from FICA. It is calculated using the employee’s Form W-4 and the applicable IRS method, not by adding an income tax bracket to the FICA rate. The IRS Employer’s Tax Guide describes federal employment tax rates and employer responsibilities.
For contingent workforce programs, assignment length does not by itself determine whether payroll taxes apply. A contingent worker treated as an employee is generally subject to the applicable employee withholding and employer taxes. Federal tax treatment depends on the actual working relationship rather than only the contract label. The IRS describes the relevant employment relationship through the common-law employee concept. State classification tests may differ from federal standards, so classification should be checked under the rules that apply.
When TCWGlobal serves as employer of record for contingent employees, the employing entity’s payroll responsibilities and the way employer taxes are reflected in assignment costs are practical details for the program to establish. Clients should know who handles payroll information and communicate changes in work location or assignment status before affected payroll is processed. For a genuinely self-employed individual, different rules apply and the worker may owe self-employment tax. The classification decision should follow the applicable legal tests rather than a preference about which party pays tax.
