What is state payroll tax?

State payroll taxes include income tax, unemployment tax, and local taxes in some states and cities. Income taxes are paid by employees, and unemployment taxes are paid by business owners.

Some states don’t have an income tax, but all states have an unemployment tax and a few states and cities also have local payroll taxes. For more info, we’ve covered everything you need to know about state payroll taxes previously.

But here’s a short summary of the elements that make up state payroll taxes.

State income tax

State income tax rates are not uniform across the U.S. Nine states—Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming—do not tax regular income. Employees in these states won’t have state income tax deducted from their paychecks.

Another nine states—Colorado, Illinois, Indiana, Kentucky, Massachusetts, Michigan, North Carolina, Pennsylvania, and Utah—impose a flat tax rate. The application of this rate varies by state, so consult your state’s tax rules for specifics.

The remaining states, along with Washington D.C., have progressive tax rates based on income levels. Tax brackets range from three to twelve. Always verify current rates and brackets with your state.

State unemployment tax

All states collect unemployment tax to fund benefits for qualifying jobless individuals under the Federal Unemployment Tax Act (FUTA) and State Unemployment Tax Act (SUTA). Business rates are determined by various factors including business tenure and former employee claims. These rates are subject to annual changes.

Local taxes

Local payroll taxes may apply depending on your state or city. Examples include Oregon's statewide transit tax and local taxes like California's Employment Training Tax (ETT) and State Disability Insurance (SDI), with the former paid by employers and the latter by employees. To avoid unexpected liabilities, confirm applicable local taxes with relevant government agencies before processing payroll.

States with no income tax

In states without an income tax, employers' payroll tasks are streamlined to federal obligations and any applicable state-specific taxes such as unemployment insurance. Here’s what employers in these states need to focus on:

• Federal payroll taxes: All employers must comply with federal tax obligations, including withholding Social Security and Medicare taxes under FICA.
• State unemployment insurance tax: Employers need to contribute to their state's unemployment insurance fund, with rates and policies varying by state.

This applies in:

• Alaska
• Florida
• Nevada
• South Dakota
• Texas (known as the Texas Unemployment Tax)
• Washington (includes workers' compensation insurance)
• Wyoming

States with flat income tax rates

Employers in states with flat income tax rates should withhold state income tax at the uniform rate provided by the state. Additionally, they must handle unemployment insurance and federal payroll taxes:

• Colorado
• Illinois
• Indiana (employers also need to manage county tax rates)
• Massachusetts
• Michigan
• North Carolina
• Pennsylvania (local tax considerations may also apply)
• Utah
• Kentucky

States with progressive income tax

For states with progressive income tax systems, employers must regularly update withholding tables to align with the varying tax brackets and rates. Employers are also responsible for state unemployment tax and federal payroll taxes. The list below includes states with progressive income tax systems, but it's essential for employers to check for any state-specific regulations that may affect payroll:

• Alabama

Other states

Some states have unique tax rules that employers must be aware of:

• New Hampshire: No state income tax is withheld, but taxes on dividend and interest income are applicable.
• Tennessee: Similar to New Hampshire, with the addition of the state tax on dividend and interest income. Employers should also handle federal payroll and unemployment taxes.

Reporting and Filing Requirements

As a business owner, you’ll need to adhere to various reporting and filing requirements to ensure compliance with payroll taxes:

• Federal Compliance: Annually file W-2 forms reporting wages and taxes withheld for each employee. Use Form W-3 to summarize these W-2s when submitting to the Social Security Administration. Quarterly, file Form 941 or annually Form 944 to report wages paid, and taxes collected for income, Social Security, and Medicare.
• State-Specific Reports: Depending on the state, you may be required to file additional quarterly reports. For instance, California businesses must submit DE 9 and DE 9C forms for unemployment insurance and state disability insurance contributions.
• Unemployment Insurance: Most states require quarterly filings to report wages and pay state unemployment insurance tax. The form names and specific requirements vary by state.
• New Hire Reporting: States also mandate reporting of new hires to track child support obligations.
• Local Taxes: Some localities require separate filings for taxes such as local income, school district, or other municipal taxes.
• Deadlines and Forms: Each state and locality may have different deadlines and forms. It is essential to consult your state's Department of Revenue and Employment website or a tax professional for the correct forms and filing schedules.
