What Is a US Payroll Tax?

US Payroll Tax

Payroll tax can be described as taxes that must be deducted from an employee’s salary and are then paid to the concerned agencies of the government. Payroll taxes are used by the government to finance various projects, including Social Security, Medicare, and income taxes. It is a responsibility shared by employees and employers.

The Social Security tax and income taxes are generally deducted automatically around the time of every paycheck, but it's good to know how they are broken down so that a person can check his or her deductions and budget accordingly every month.

Why Use a US Payroll Tax Calculator?

A US payroll tax calculator helps you calculate the taxes before or after you receive your paycheck. While you could only guess the taxes due to earnings limits, you will find the information clearer from the calculator, considering federal taxes, contributions, and earnings limits.

A payroll calculator will also:

• Understand how much taxes are deducted from your salary
• Make an accurate estimate of your net (take-home) income

Salaried personnel, freelancers looking for payroll employment, or HR staff can benefit from this utility.
