If your business operates across the United States — or if you hire remote employees in multiple states — you already know that payroll gets complicated fast. Multi-state payroll isn’t just about running numbers. It involves navigating different state income tax requirements, unemployment insurance rates, workers’ compensation rules, and filing deadlines across every state where you have employees.
At Southern Payroll & Bookkeeping, we specialize in multi-state payroll for small and mid-sized businesses throughout the Southeast. Here’s what every business owner should understand before their first multi-state payroll run.
What Makes Multi-State Payroll Different?
When you pay employees in more than one state, you take on separate compliance obligations in each state. These include state income tax withholding (not all states have income tax — Tennessee eliminated individual income tax in 2021, but Georgia and Alabama both have it), state unemployment insurance (SUI) rates that vary by employer and state, workers’ compensation insurance requirements that differ by state, and local taxes in certain cities and counties.
The most common mistake small business owners make is assuming payroll works the same across state lines. It doesn’t. And the penalties for getting it wrong — underpaying SUI, filing in the wrong state, or missing a registration deadline — can be costly.
State-by-State Payroll Overview: TN, GA & AL
Tennessee Payroll
Tennessee has no state income tax on wages, which simplifies withholding. However, Tennessee employers are still responsible for federal payroll taxes, FUTA, and Tennessee’s state unemployment insurance (SUTA). Tennessee SUTA rates range from 0.01% to 10%, depending on your employer experience rating.
Georgia Payroll
Georgia has a flat individual income tax rate (recently moving toward a 5.39% flat rate under ongoing legislation). Georgia employers must withhold state income tax, register for a Georgia withholding number, and file Georgia G-7 quarterly withholding returns. Georgia SUTA rates vary based on employer experience.
Alabama Payroll
Alabama has a progressive individual income tax with rates ranging from 2% to 5%. Alabama employers must register with the Alabama Department of Revenue and file A-1 or A-3 withholding returns. Certain Alabama cities — including Birmingham and Montgomery — also have local occupational taxes that must be withheld and remitted separately.
Nexus: When Does a State Tax Obligation Begin?
Payroll nexus is triggered when you have an employee working in a state — even temporarily, even remotely. If your Chattanooga business hires a remote employee in Atlanta, you now have Georgia payroll obligations. This is a common surprise for growing businesses expanding across state lines.
Before you hire your first out-of-state employee, make sure you’ve registered for the appropriate state employer accounts and set up correct tax withholding in your payroll software.
