How Payroll Taxes Work in the US

Payroll taxes are levied on employee wages and are collected by employers through payroll deductions. These taxes fund various government programs and services. The two main types of payroll taxes are:

Federal Income Tax (FIT)
Social Security and Medicare Taxes

Employers must withhold these taxes from employee paychecks and remit them to the government. The rates and thresholds for these taxes change annually, so it's important to use current information when calculating payroll taxes.

Types of Payroll Taxes

There are several types of payroll taxes in the US, each serving different purposes:

The federal income tax is a progressive tax that varies by income level. It's calculated based on the employee's taxable wages and the applicable tax brackets.

2. Social Security Tax

The Social Security tax is a pay-as-you-go program that funds retirement, disability, and survivor benefits. The current rate is 6.2% for both employees and employers.

3. Medicare Tax

The Medicare tax funds healthcare programs for all Americans. The current rate is 1.45% for both employees and employers, with an additional 0.9% for wages over $200,000.

Payroll Tax Formula

Total Payroll Tax = Federal Income Tax + Social Security Tax + Medicare Tax

Social Security Tax = Wages × 6.2%

Medicare Tax = Wages × 1.45% + (Wages over $200,000 × 0.9%)
