Payroll tax and income tax can both appear as deductions from an employee’s paycheck, but they are not the same. Payroll taxes primarily fund Social Security, Medicare, and unemployment programs. Federal income tax supports general government spending and is calculated using progressive tax rates.
Employers must calculate, withhold, deposit, and report several of these taxes. They also pay their own share of certain payroll taxes. This guide explains who pays each tax, how the 2026 rates work, and what employers must do to remain compliant.
What Is the Difference Between Payroll Tax and Income Tax?
Payroll taxes apply to wages and generally fund specific social insurance programs. Social Security and Medicare taxes are shared by employees and employers, while federal unemployment tax is normally paid only by the employer. Income tax is an employee’s tax liability based on taxable income, filing status, adjustments, deductions, and credits. The employer withholds an estimated amount from wages but does not match the employee’s federal income tax.
In short, payroll tax is generally calculated using set rates on covered wages, while income tax uses progressive rates and individual tax information. Employers administer both through payroll, but the money serves different purposes and the payment obligations are different.
Payroll Tax vs. Income Tax at a Glance
| Question | Payroll tax | Income tax |
|---|---|---|
| What does it generally fund? | Social Security, Medicare, and unemployment programs | General federal, state, and local government spending |
| Who pays it? | Employees and employers pay FICA; employers generally pay FUTA and SUTA, although state rules vary | The employee or individual taxpayer; the employer withholds and remits amounts from wages |
| How is it calculated? | Set percentages applied to wages, sometimes only up to a wage base | Progressive rates applied to taxable income |
| What income does it cover? | Generally wages and other employment compensation subject to the applicable tax | Potentially wages, business income, interest, dividends, capital gains, and other taxable income |
| Does the employer match it? | Employers normally match the employee Social Security and Medicare portions; there is no employer match for Additional Medicare Tax | No |
| Common federal forms | Forms 941, 940, W-2, and W-3 | Form W-4 determines withholding; withheld amounts are reported on Forms 941 and W-2 |
The term employment taxes is sometimes used broadly to include federal income tax withholding, Social Security, Medicare, and FUTA. That administrative grouping does not mean federal income tax and payroll tax are economically or legally identical.
What Are Payroll Taxes?
Payroll taxes are taxes connected to employee wages. In the United States, the main federal payroll taxes are Social Security and Medicare taxes under the Federal Insurance Contributions Act, commonly called FICA, and federal unemployment tax under FUTA. Employers may also owe state unemployment and other state or local employment taxes.
For a broader employer-focused explanation, see which payroll taxes employers pay.
Social Security tax
For 2026, Social Security tax is 6.2% for the employee and 6.2% for the employer. The combined rate is 12.4%. The tax applies to covered wages up to the 2026 Social Security wage base of $184,500. Once an employee’s covered wages from that employer reach the annual wage base, Social Security withholding normally stops for the remainder of the year.
Medicare tax
The regular Medicare tax rate is 1.45% for the employee and 1.45% for the employer, for a combined rate of 2.9%. Unlike Social Security tax, regular Medicare tax has no annual wage limit. These 2026 figures are published in IRS Topic No. 751.
Additional Medicare Tax
An additional 0.9% Medicare tax may apply to an individual’s Medicare wages, Railroad Retirement Tax Act compensation, and self-employment income above a threshold determined by filing status. An employer must begin withholding the additional 0.9% from wages it pays to an employee above $200,000 in a calendar year, regardless of that employee’s filing status. The employer does not match the Additional Medicare Tax.
The employee’s final liability can differ from the amount withheld because the tax-return threshold depends on filing status and may consider wages from multiple employers or a spouse. The IRS explains this distinction in its Additional Medicare Tax questions and answers.
Federal unemployment tax
FUTA helps fund the federal-state unemployment insurance system and is generally paid by employers, not withheld from employees. For 2026, the standard FUTA rate is 6.0% on the first $7,000 of wages paid to each employee. Employers that qualify for the maximum 5.4% state unemployment tax credit have an effective FUTA rate of 0.6%, or a maximum of $42 per employee before any credit-reduction adjustment.
Eligibility for the full credit depends on the employer’s state unemployment tax position, and employers in a FUTA credit-reduction state may owe more. Consult IRS Publication 15 and the current Form 940 instructions before calculating the liability.
State unemployment and other state payroll taxes
State unemployment insurance, often called SUTA or SUI, varies by state. Rates and wage bases can depend on the employer’s industry, claims history, location, and experience rating. Some jurisdictions also administer disability insurance, paid family leave, local occupational taxes, or other payroll-related programs. Employers should confirm requirements with every state and locality where an employee works.
What Is Income Tax Withholding?
Federal income tax withholding is a prepayment toward the employee’s expected annual federal income tax. The employer deducts the calculated amount from the employee’s wages and deposits it with the U.S. Treasury. The employer does not pay a matching federal income tax amount.
Withholding depends on factors that can include:
- The employee’s taxable wages for the pay period
- Pay frequency
- Filing status and other information on Form W-4
- Multiple jobs or a working spouse
- Dependents, deductions, credits, or additional requested withholding
- Current IRS withholding tables and procedures
Federal income tax rates are progressive. For 2026, the statutory marginal rates remain 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Moving into a higher bracket does not cause all of a person’s income to be taxed at the higher rate. Only the portion within that bracket is taxed at that rate. Current thresholds are available in the IRS 2026 inflation-adjustment guidance.
State and local income-tax withholding follows the rules of the applicable jurisdictions. An employer may need to consider where the employee performs services, where the employee lives, reciprocity agreements, and local withholding requirements. The employer’s office location alone does not always determine the correct withholding state.
Payroll Tax vs. Income Tax Calculation Example
Assume an employee earns $2,000 in regular wages during one pay period. The employee has not reached the Social Security wage base, and all $2,000 is subject to Social Security and Medicare tax.
Employee FICA withholding
- Social Security: $2,000 × 6.2% = $124.00
- Medicare: $2,000 × 1.45% = $29.00
- Total employee FICA withholding: $153.00
Employer FICA contribution
- Employer Social Security: $124.00
- Employer Medicare: $29.00
- Total employer FICA contribution: $153.00
Federal income tax withholding cannot be calculated accurately from gross pay alone. It must be determined using the employee’s Form W-4, pay frequency, taxable wages, and the applicable IRS withholding method. State and local deductions may also apply.
FUTA is a separate employer cost. If this is the employee’s first $2,000 of FUTA-taxable wages for the year and the employer qualifies for the full credit, the effective FUTA amount associated with those wages would be $12.00 at a 0.6% rate. The actual FUTA liability depends on eligibility, prior wages, exemptions, and any credit-reduction adjustment.
What this example shows
The employee sees FICA and estimated income tax taken from the paycheck. The employer remits those withheld amounts and also funds its own FICA share and applicable unemployment taxes. Income-tax withholding is not an additional matching tax paid by the employer.
Employer Payroll-Tax Responsibilities
An employer’s responsibility goes beyond calculating deductions. Amounts withheld from employees are held for the government and must be deposited and reported correctly. Outsourcing payroll administration can reduce operational workload, but the IRS notes that an employer generally remains responsible for its federal tax obligations even when it uses a third-party payer.
- Collect an accurate Form W-4 – Use the employee’s current withholding certificate and update payroll when the employee submits a valid replacement.
- Classify workers correctly – Employees and independent contractors are subject to different withholding and reporting rules. Review the relevant worker-classification factors before processing pay.
- Calculate taxable wages – Gross wages and wages subject to federal income tax, Social Security, Medicare, and FUTA are not always identical. Pretax benefits and fringe benefits may receive different treatment.
- Withhold employee taxes – Calculate federal income tax, the employee share of FICA, Additional Medicare Tax when the employer withholding threshold is crossed, and applicable state or local taxes.
- Calculate employer taxes – Account for the employer share of Social Security and Medicare, FUTA, SUTA, and any jurisdiction-specific employer assessments.
- Deposit taxes on time – Federal employment-tax deposits may follow monthly, semiweekly, quarterly, or next-day requirements depending on the tax and applicable rules. Filing a return and depositing tax are separate obligations.
- File and reconcile reports – Reconcile the payroll register, deposits, quarterly returns, and year-end wage statements before filing.
- Retain payroll records – Maintain the records required to support wage calculations, withholding, deposits, employee classifications, and filings.

Payroll Tax and Income Tax for Self-Employed Workers
Self-employed individuals generally do not have an employer withholding FICA from a paycheck. Instead, they may owe self-employment tax under SECA to fund Social Security and Medicare. The headline self-employment tax rate is generally 15.3%, consisting of 12.4% for Social Security and 2.9% for Medicare, subject to applicable wage bases, thresholds, and calculation rules.
A self-employed person may also need to make estimated income-tax payments during the year. Self-employment tax and income tax are separate calculations, even when both are paid through estimated payments or reported on the same individual return. Business structure, net earnings, additional Medicare tax, credits, and deductions can change the final amount, so individual advice may be necessary.
Common Payroll-Tax Mistakes Employers Should Avoid
Treating all paycheck deductions as the same tax
Federal income tax withholding, FICA, benefit deductions, garnishments, and state programs follow different rules. Combining them under one label makes reconciliation and employee communication harder.
Using outdated wage bases or withholding tables
Social Security wage bases and income-tax withholding procedures can change annually. Update payroll settings before the first payroll of the new year and document the effective date.
Applying the employee’s tax-return threshold to Additional Medicare withholding
The employer withholding trigger is wages above $200,000 paid by that employer during the calendar year, without regard to filing status. The employee resolves any difference when filing Form 8959.
Missing a deposit while still filing the return
Submitting Form 941 does not replace the duty to deposit employment taxes on the applicable schedule. The IRS failure-to-deposit penalty can range from 2% to 15% depending on timing and circumstances.
Misclassifying a worker
Calling a worker an independent contractor does not by itself determine tax status. Control, independence, and the overall working relationship matter. Misclassification can create withholding, reporting, wage, and benefit liabilities.
Failing to reconcile payroll records
Payroll registers, tax deposits, Forms 941, and Forms W-2 should agree. A consistent monthly and quarter-end reconciliation process can identify discrepancies before year-end reporting. Review these additional common payroll risks when designing controls.
Are Employer Payroll Taxes Tax-Deductible?
Employer-paid federal employment taxes are generally deductible as ordinary and necessary business expenses, subject to applicable tax rules and reductions for certain credits. This can include the employer share of Social Security and Medicare taxes and qualifying unemployment taxes.
The employee portion withheld from wages is different. It is part of the employee’s compensation that the employer remits to the government on the employee’s behalf, not an additional employer tax expense. Employers should work with a qualified tax adviser to determine the treatment of specific taxes, credits, and payroll costs.

Frequently Asked Questions About Payroll Tax vs. Income Tax
Are payroll tax and income tax the same?
No. Payroll taxes generally fund Social Security, Medicare, and unemployment programs and are tied to wages. Income tax is based on taxable income and funds broader government operations. Both may be processed through payroll, but they use different calculations and payment rules.
Do employees pay both payroll tax and income tax?
Many employees pay both. Their paychecks may include Social Security and Medicare withholding as well as federal, state, or local income-tax withholding. Eligibility, exemptions, taxable wages, and jurisdiction determine the actual deductions.
Which payroll taxes does an employer pay?
Employers generally pay a matching 6.2% Social Security tax and 1.45% Medicare tax on covered wages. They also generally pay FUTA and state unemployment tax. State and local employer taxes vary.
Does an employer pay an employee’s income tax?
No. The employer generally withholds federal income tax from the employee’s wages and remits it to the government. The employer does not match that income-tax withholding.
Is FICA a payroll tax?
Yes. FICA consists of Social Security and Medicare taxes. Employees and employers normally pay equal shares of regular FICA taxes, while Additional Medicare Tax has no employer match.
Is FUTA deducted from an employee’s paycheck?
Generally, no. FUTA is an employer-paid federal unemployment tax and should not be withheld from employee wages.
What is the 2026 Social Security wage base?
The Social Security wage base for 2026 is $184,500. Regular Medicare tax has no wage base limit.
What happens if payroll taxes are deposited late?
The IRS may assess a failure-to-deposit penalty. Rates generally progress from 2% to 15% depending on how late the deposit is and whether the amount remains unpaid after notice. Interest and other consequences may also apply.
Can employer payroll taxes be deducted as a business expense?
Employer-paid employment taxes are generally deductible as ordinary and necessary business expenses, subject to applicable tax rules and credits. Employee amounts withheld and remitted are treated differently because they are part of employee compensation.
Does outsourcing payroll transfer the employer’s tax liability?
Not necessarily. A provider may calculate, deposit, and file taxes for the employer, but the employer generally remains responsible for federal employment-tax obligations. Employers should verify deposits, filings, service agreements, and the provider’s authorization.
