How To Calculate Payroll Tax In the United States: Examples & Tips for Employers

What Are Payroll Taxes, and Why Are They Important?

Payroll taxes are mandatory contributions employers withhold from employee wages and pay themselves to fund programs like Social Security, Medicare, and unemployment insurance. In the U.S. payroll taxes follow fixed federal rates and wage caps that every U.S. employer must apply correctly on every payroll run.

Getting this right matters for two reasons. First, miscalculations are expensive. The IRS (International Revenue Service) issues billions in payroll-related penalties every year, and the most common cause is failing to deposit withheld taxes on the correct schedule. 

Second, faulty paychecks erode trust within your team. Nothing damages an employer brand quicker than a payroll error that shows up on payday. Accurate payroll taxes also give you a clearer view of your true cost of employment, which feeds into hiring budgets and headcount planning.

What Are The Types Of Payroll Taxes U.S. Employers Must Pay?

Payroll taxes fall into two buckets: taxes you withhold from employee wages, and taxes you pay directly as the employer. Here's the breakdown of the tax types you need to be aware of for 2026.

1. Federal Income Tax

You withhold federal income tax from every paycheck based on the employee's Form W-4 and the IRS wage bracket tables in Publication 15-T. The amount depends on the employee's taxable wages, filing status, dependents, and any extra withholding they've requested.

IRS Wage Bracket Tables (Publication 15-T)

The IRS wage bracket tables in Publication 15-T are lookup tables employers use to determine how much federal income tax to withhold based on an employee’s wages, filing status, and Form W-4. Instead of calculating percentages manually, you match the employee’s pay to a wage range and apply the corresponding withholding amount.

Example of a Weekly Wage Bracket Table (2026, Simplified – Single Filers, Standard Withholding)

Note: Actual IRS tables include hundreds of rows and vary by filing status, pay frequency, and W-4 adjustments. Employers typically use payroll software or the percentage method for precision.

2. Federal Insurance Contributions Act (FICA) Taxes

FICA covers Social Security and Medicare. Employers and employees split these contributions:

• Social Security Tax: 6.2% (employee) + 6.2% (employer) = 12.4% total, applied to wages up to the 2026 wage base of $184,500.
• Medicare Tax: 1.45% (employee) + 1.45% (employer) = 2.9% total, with no wage cap.
• Additional Medicare Tax: Employees earning over $200,000 (single) or $250,000 (married filing jointly) pay an extra 0.9%. Employers don't match this.

3. Federal Unemployment Tax Act (FUTA)

FUTA is an employer-only tax that funds federal unemployment benefits. The headline rate is 6.0% on the first $7,000 of each employee's wages, but most employers qualify for the 5.4% state unemployment credit, which drops the effective rate to 0.6% – so $42 per employee per year for employers in good standing.

4. State Income Tax

Most states require you to withhold state income tax based on the state's own withholding tables. Nine states – Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming – don't impose a state income tax on wages, which simplifies your calculation but doesn't eliminate state filing requirements.

See state-specific tax and other compliance details in our State Hiring Guides.

5. State Unemployment Tax Act (SUTA)

SUTA is the state-level equivalent of FUTA, and it's almost always paid by the employer. Each state sets its own rate based on your industry, your unemployment claims history, and the state's wage base. New employers usually start at a default rate and move up or down based on layoff history.

6. Local Payroll Taxes

Some cities, counties, and special districts layer additional payroll taxes on top of federal and state obligations. These aren’t standardized, which makes them one of the easiest compliance gaps for employers hiring across multiple locations.

The most common types include local income taxes (like New York City or Yonkers resident taxes), city-specific wage taxes (such as Philadelphia’s), and school district income taxes in parts of Ohio. In some jurisdictions, you’ll also see transit or mobility taxes tied to where employees work, like New York’s Metropolitan Commuter Transportation Mobility Tax (MCTMT), or local business payroll taxes in cities like San Francisco.

How To Calculate Payroll Taxes: Step-By-Step With Examples

Here's the full process, step by step. Use this as your checklist every pay run until it becomes muscle memory.

1. Calculate Employees' Gross Pay

Gross pay is what the employee earns before any deductions.

• Hourly Employees: Multiply hours worked by the hourly wage. Overtime (anything over 40 hours per week) is paid at 1.5 times the regular rate.
• Salaried Employees: Divide annual salary by the number of pay periods in the year (biweekly = 26, semi monthly = 24, monthly = 12).

2. Subtract Pre-Tax Deductions

Before you calculate any taxes, subtract pre tax deductions from gross pay. 

These include:

• 401(k) and traditional retirement contributions
• Health insurance premiums on a Section 125 plan
• HSA (Health Savings Account) and FSA (Flexible Spending Account) contributions
• Commuter benefits

These deductions reduce the wages subject to federal income tax, and most also reduce the wages subject to FICA. Getting this order right is the single most common place small employers slip up.

3. Calculate FICA (Social Security and Medicare)

FICA is a flat-rate calculation, which makes it the easiest part of the run.

• Social Security: 6.2% of wages up to the $184,500 cap (2026). Employer matches 6.2%.
• Medicare: 1.45% of all wages. Employer matches 1.45%. Add 0.9% on employee wages over $200,000 (no employer match).

4. Apply Federal Income Tax Withholding

This is where the W-4 and IRS Publication 15-T come in. 

Follow these steps:

1. Pull the employee's filing status from their W-4 (single, married filing jointly, head of household).
2. Check whether they used the 2020+ W-4 (which uses dollar amounts) or pre-2020 W-4 (which uses allowances).
3. Apply the correct wage bracket or percentage method table from Publication 15-T.
4. Account for any additional withholding the employee requested on Line 4(c) of the W-4.

5. Add State and Local Income Tax

Use your state's withholding certificates and tax tables to calculate state income tax. Then layer on any local income tax (city, county, or school district) for the employee's work location and, in some states, their residence.

6. Subtract Post-Tax Deductions

After tax withholdings, deduct any post-tax items:

• Wage garnishments (child support, federal tax levies, court-ordered payments)
• Roth 401(k) contributions
• Union dues
• Voluntary benefits paid after tax (e.g., supplemental life insurance)

What's left is the employee's net pay.

7. Calculate the Employer's Share of Payroll Taxes

You're not done when the employee's paycheck is finalized. You also owe:

• Social Security: 6.2% (matching the employee)
• Medicare: 1.45% (matching the employee)
• FUTA: 0.6% effective rate on the first $7,000 of wages
• SUTA: Your state-assigned rate, applied to your state's wage base

8. Deposit Payroll Taxes

You don't sit on withheld taxes, you need to deposit them on a strict schedule to avoid non-compliance and accompanying penalties..

• Federal Taxes (income tax + FICA): Deposited via the IRS EFTPS system. Most small employers are on a monthly schedule; larger employers deposit semi-weekly. The IRS assigns your schedule based on your prior-year tax liability.
• FUTA: Deposited quarterly if your liability exceeds $500.
• State taxes: Deadlines vary by state – check with your state department of revenue.

9. File the Right Forms (and Make Payments to the IRS)

Reporting runs on a quarterly and annual cadence:

• IRS Form 941 (quarterly): Reports withheld federal income tax, Social Security, and Medicare.
• IRS Form 940 (annual): Reports FUTA tax.
• Forms W-2 and W-3 (annual): Report wages and withholdings to employees and the SSA.
• State Equivalents: Each state has its own quarterly and annual filings.

Examples of Payroll Tax Calculations

Let’s take a look at two quick worked examples to put all of these steps together.

Example 1: Hourly Employee

A worker earns $20/hour and works 45 hours in a week.

Example 2: Salaried Employee

A salaried employee earns $60,000 per year, paid biweekly. These show how each tax component shapes take-home pay – and why two employees with similar gross wages can end up with very different paychecks depending on filing status and state.

Payroll Taxes vs Total Employment Cost

Payroll taxes are only one slice of what an employee actually costs you. When you're budgeting headcount or comparing offers across markets, the full picture includes benefits, bonuses, statutory leave, insurance contributions, and the admin overhead of running compliant payroll. 

As a rule of thumb, total employment cost typically runs 1.25× to 1.4× base salary in the U.S.

‍

This is why a $100,000 hire usually costs $125,000–$140,000 fully loaded – and why payroll tax accuracy is just the entry point to running a clean cost-of-employment model.

What Do You Need to Calculate Payroll Tax?

Before you run a single calculation, you need to gather the right paperwork and information for each employee. Skip any of these and you're either setting yourself up for an incorrect withholding amount or a compliance gap.

W-4 Certification

Form W-4, the Employee's Withholding Certificate, is filled in by the employee at hire. It captures their filing status, dependents, and any additional withholding they want. You use it to determine federal income tax withholding for every paycheck.

I-9 Form

Form I-9 verifies identity and US work authorization. You're required to collect it for every new hire and keep it on file – along with the supporting documents you reviewed (passport, Social Security card, etc.).

State Withholding Forms

Most states have their own version of the W-4 (NY's IT-2104, CA's DE 4, and so on). Use these to set up state income tax withholding correctly for each employee's work and residence location.

Employment Status

Classify every worker correctly as either an employee (W-2) or an independent contractor (1099). The misclassification penalties are steep – back taxes, interest, and potential FLSA exposure – and the IRS and DOL (Department of Labor) have both increased enforcement in recent years.

Taxable Deductions

Document every pre-tax deduction (health insurance, 401(k), HSA, FSA, commuter benefits) and every post-tax deduction (Roth contributions, garnishments, union dues). These determine which wages are subject to which taxes, and getting the order wrong throws off the whole calculation.

‍

Top Tips to Avoid Payroll Tax Errors

Calculating payroll taxes for employees across multiple states gets complex fast. Here are a few good habits to form that’ll help you keep errors out of your filings:

• Verify W-4 data matches withholding amounts – check that the amount actually being withheld lines up with the elections on the W-4 every quarter.
• Watch wage base limits for Social Security ($184,500) and FUTA ($7,000) so you stop withholding or remitting at the right point.
• Use payroll software to automate the math, apply current rates, and flag anomalies before they hit the bank.
• Lean on payroll analytics to spot trends, catch underpayments, and surface compliance risk across multi-state teams.
• Run quarterly payroll audits before you file Form 941 – it's cheaper to fix an error in your books than after the IRS sees it.
