A Guide to Understanding What Makes Up Payroll Taxes
Once you hire staff, you must start paying payroll taxes for each new employee you take on. Payroll taxes include federal income, Social Security and Medicare. Depending on where your business is, this may also include state and city taxes.
Before paying taxes, all businesses must acquire a Federal Employer Identification Number (EIN) from the US government. Once a business has an EIN, they can file payroll taxes with the government.
Employers are required to withhold the full amount of federal income tax. Employers are also required to withhold half of the Social Security tax and half of the Medicare tax from each employee’s paycheck, and pay the remaining half of Social Security and Medicare taxes themselves.
What Factors Make Up Payroll Taxes
Federal Income Tax
- To figure out federal taxes, employers should have employees fill out a mandatory IRS W-4 form. This form is used to figure out federal taxes, and state and city taxes where applicable. To calculate total federal tax, use the employee's W-4, Employer's Tax Guide and Supplemental Employer's Tax Guide.
Social Security Tax
- Social Security tax makes up one half of FICA (Federal Insurance Contributions Act). The tax rate for Social Security during 2018 was 6.2 percent of each employee’s salary, with the employer paying a matching amount. Both the employer and employee are only responsible for a limited amount of Social Security tax. This amount is paid for anything earned up to a wage base of $128,400 for the year 2018.
- The other half of FICA is Medicare. Employers must withhold 1.45 percent of each employee's salary for the Medicare tax. Also, employers must pay a matching amount.
- In addition to the payroll taxes listed above, employers must pay an unemployment tax for each individual that works at the company. This is called State and Federal Unemployment Taxes (SUTA and FUTA). The tax rate for FUTA is 6.0 percent, and it's applied to the first $7,000 paid in wages to each employee during the year. Employers who pay their SUTA on a timely basis receive an offset credit of up to 5.4 percent. SUTA taxes vary by state.
State Income Tax
- Depending on the state where a business is located, employers and employees may be required to pay state income tax. Taxes vary by state.
City and County Income Tax
- Though there aren’t many cities or counties with an income tax, a few, like New York City, do have this tax. Check with the local government to see if there is an applicable local tax.
Penalties for Non-Payment of Payroll Taxes
The requirement to submit payroll taxes is enforced by a system of strict penalty assessments. Companies receive an automatic penalty from 2 percent to 10 percent for not paying federal payroll taxes properly and promptly, and state and city taxing entities assess similar penalties.
A business will also receive additional penalties for not filing monthly, and quarterly payroll tax returns, and forgetting to submit a W-2 form for each new employee could cost $50 per form that wasn't filed promptly.
The IRS enforces a much more severe penalty for companies that don't submit their withholding and social security tax fund payments as required. The IRS will charge a penalty of up to 100 percent of the unpaid amount to any company or individual, such as a corporate executive in charge of making sure the payments take place.
