In our paycheck calculators, SUI is used to refer to the unemployment tax paid by the employee. AK, NJ, and PA have an employee unemployment tax.

The federal income tax is a tax on annual earnings for individuals, businesses, and other legal entities. All wages, salaries, cash gifts from employers, business income, tips, gambling income, bonuses, and unemployment benefits are subject to a federal income tax.

For each payroll, federal income tax is calculated based on wages and the answers provided on the W-4 and year to date income, which is then referenced to the tax tables in IRS Publication 15-T. The current tax rates are 0%, 10%, 12%, 22%, 24%, 32%, 35%, or 37%. Again, the percentage chosen is based on the paycheck amount and your W4 answers.

Social Security tax is 6.2% on $147,000 of earned income. The maximum Social Security tax for employees is $9,114. Social Security is also known as OASDI (Old Age, Survivors, and Disability Insurance). Employees can log into www.ssa.gov to verify their wages and confirm their benefits at various retirement ages.

Medicare is meant to supplement an employee’s healthcare benefits when they reach retirement age. Both employers and employees are required to contribute to Medicare at a rate of 1.45%. For employees, there is an additional 0.9% Medicare tax on wages earned after a $200,000 threshold ($250,000 for married filing jointly, or $125,000 for married filing separately). This means when an employee’s income reaches the threshold in a calendar year, the employer should withhold 2.35% for the employee’s Medicare, and it’s called the Additional Medicare Tax. The Social Security and Medicare taxes are collectively known as FICA (Federal Insurance Contributions Act). Discover how FICA taxes impact your paycheck and benefits.
