Free Payroll Tax Calculator (2026)

How This Free Payroll Tax Calculator Works

Payroll taxes are split between employees and employers. Employees pay federal income tax withholding and their share of FICA taxes (Social Security and Medicare). Employers pay a matching share of FICA taxes on top of the employee’s gross wages. This free payroll tax calculator shows both sides of the equation in a single calculation.

Step 1 — Gross Wages and Pay Period

Enter the employee’s gross wages per pay period and select how often they are paid. The calculator annualizes the wages to calculate accurate federal income tax withholding and FICA taxes, then converts the results back to a per paycheck amount.

Step 2 — Pre-Tax Deductions

Pre-tax deductions such as 401(k) contributions and HSA contributions reduce the amount of wages subject to federal income tax withholding. However, FICA taxes (Social Security and Medicare) are calculated on the full gross wages before pre-tax deductions in most cases.

Step 3 — Employee FICA Taxes

The employee pays 6.2% Social Security tax on gross wages up to the $168,600 wage base and 1.45% Medicare tax on all gross wages. These amounts are withheld directly from the employee’s paycheck.

Step 4 — Employer FICA Taxes

The employer pays a matching 6.2% Social Security tax and 1.45% Medicare tax on the employee’s gross wages. This is an additional cost to the employer above and beyond the employee’s gross wages. The calculator shows the total employer cost per paycheck including both gross wages and employer FICA.

Step 5 — Federal Income Tax Withholding

Federal income tax withholding is estimated using the annualized wage method with the 2026 tax brackets and standard deduction. The annual tax is divided by the number of pay periods to calculate the per paycheck withholding amount.

Frequently Asked Questions

What are payroll taxes?

Payroll taxes are taxes withheld from an employee’s paycheck and paid by both the employee and employer to fund federal programs. They include federal income tax withholding, Social Security tax, and Medicare tax. Employers are also responsible for federal unemployment tax (FUTA) and state unemployment tax (SUTA), which are not included in this calculator.

What is the Social Security tax rate for 2026?

The Social Security tax rate is 6.2% for both the employee and employer in 2026. The employee pays 6.2% withheld from their paycheck and the employer pays a matching 6.2%. Social Security tax only applies to the first $168,600 of wages — the 2026 Social Security wage base. Wages above that amount are not subject to Social Security tax for the remainder of the year.

What is the Medicare tax rate for 2026?

The Medicare tax rate is 1.45% for both the employee and employer with no wage cap. All wages are subject to Medicare tax regardless of how much the employee earns. High earners over $200,000 (single) or $250,000 (married filing jointly) also pay an additional 0.9% Additional Medicare Tax, which is not included in this calculator.

What is the total FICA tax rate?

The total FICA tax rate is 15.3% — split equally between employee and employer at 7.65% each. The employee’s 7.65% consists of 6.2% Social Security and 1.45% Medicare. The employer pays a matching 7.65%. Self-employed individuals pay the full 15.3% themselves, which is why self-employment tax equals the combined FICA rate.

How is federal income tax withholding calculated from a paycheck?

Federal income tax withholding is calculated using the IRS percentage method. The employee’s per period wages are annualized, reduced by the standard deduction based on filing status, and then the applicable 2026 tax brackets are applied. The resulting annual tax is divided by the number of pay periods to determine per paycheck withholding. Employees can adjust their withholding by submitting a new W-4 form to their employer.

What payroll taxes does the employer pay?

Employers are responsible for the following payroll taxes: matching Social Security tax (6.2%), matching Medicare tax (1.45%), federal unemployment tax (FUTA at 6% on the first $7,000 of wages, reduced by state credits), and state unemployment tax (SUTA, which varies by state). This calculator covers the employer FICA match only and does not include FUTA or SUTA.

Do pre-tax deductions reduce FICA taxes?

Most pre-tax deductions reduce federal income tax withholding but do not reduce FICA taxes. For example, 401(k) contributions reduce the wages subject to federal income tax but Social Security and Medicare taxes are still calculated on the full gross wages. Health insurance premiums paid through a Section 125 cafeteria plan are one exception — they reduce both federal income tax and FICA taxable wages.

Understanding Payroll Taxes for Employers and Employees

Payroll taxes affect every working American and every business that hires employees. Understanding how payroll taxes are calculated — from the employee’s withholding to the employer’s matching contributions — helps both workers and small business owners manage their finances more effectively. This free payroll tax calculator gives you full visibility into both sides of every paycheck.

The Employee Side of Payroll Taxes

Every time an employee receives a paycheck, three federal taxes are withheld. Federal income tax is withheld based on the employee’s W-4 elections and the IRS withholding tables. Social Security tax is withheld at 6.2% on wages up to $168,600. Medicare tax is withheld at 1.45% on all wages. Together, these deductions reduce the employee’s gross pay to their net take-home amount.

The Employer Side of Payroll Taxes

Employers pay payroll taxes in addition to the employee’s gross wages. For every dollar of Social Security tax withheld from an employee’s check, the employer pays a matching dollar. The same applies to Medicare. This means the true cost of an employee to an employer is their gross wages plus 7.65% for the employer FICA match, plus any FUTA and SUTA obligations. For a small business owner budgeting for staff, understanding this total employer cost is critical.

The Social Security Wage Base

Social Security tax only applies to wages up to the annual wage base, which is $168,600 for 2026. Once an employee’s cumulative wages for the year exceed this threshold, Social Security tax stops being withheld for both the employee and the employer. Medicare tax has no wage cap and continues on all wages for the full year.

Payroll Tax Deposits and Employer Obligations

Employers must deposit withheld payroll taxes to the IRS on a schedule determined by their total tax liability. Most small employers deposit monthly. Larger employers with higher payroll tax liabilities deposit on a semi-weekly schedule. The IRS requires employers to file Form 941 quarterly to report wages paid and taxes withheld. Failure to deposit payroll taxes on time results in significant penalties.

Payroll Taxes vs. Self-Employment Tax

Self-employed individuals and independent contractors do not have an employer to split FICA taxes with. Instead, they pay the full 15.3% self-employment tax themselves — covering both the employee and employer share of Social Security and Medicare. This is why comparing W2 employment to 1099 contractor status involves more than just the gross pay difference. Use our 1099 vs W2 calculator to see the full comparison.
