Remote work has opened doors for businesses of all sizes. It has also created new tax complications that many owners don’t see coming. When your team spreads out across multiple states, your tax obligations spread out with them.
A single employee living in another state can trigger filing requirements, payroll changes, and new compliance rules.
If your business has remote workers or is considering hiring across state lines, it’s important to understand what responsibilities fall on you. Knowing the rules early prevents penalties, unexpected tax bills, and last-minute scrambling during filing season.
Why Remote Work Changes Your Tax Picture
When employees work in different states, their physical location, not your company’s, often determines tax obligations. States want their share of income tax on wages earned within their borders. They also set rules for unemployment insurance, payroll withholding, and business registration.
In the past, companies avoided these issues by keeping staff in one location. Remote hiring changed that. Now, even one worker in another state can create what’s known as “nexus,” which is the point at which your business becomes subject to that state’s tax rules.
Nexus can be triggered by:
● An employee working from home
● Sales activity in a state
● Delivering services within a state
● Having a physical presence, even a small one
Once a nexus exists, businesses may be required to file returns, withhold payroll taxes, or register with the state’s tax department.
Payroll Withholding Rules Are Not the Same Everywhere
One of the biggest adjustments for multi-state employers is payroll withholding. Each state has its own withholding requirements, and you must follow the rules where the employee performs the work.
For example, if your business is based in Michigan but your employee works from Ohio, you are responsible for withholding Ohio income tax. Some states have reciprocal agreements that simplify things, but not all do.
Failing to withhold correctly can lead to fines, interest, and frustrated employees who end up with the wrong state’s taxes on their returns. It’s not enough to rely on your payroll software alone. You must register for withholding accounts in each state where you have remote workers, and you need to know which forms and deposit schedules apply.
Unemployment Insurance Is State-Specific Too
State unemployment insurance (SUTA) is another area where rules vary. Employers must pay unemployment tax to the state where the employee performs their work, not the state where the business is located.
Most states follow a “localization” rule that assigns unemployment tax responsibility to the state where the employee spends most of their time. When an employee splits time between states, things get more complicated. Because unemployment rules differ so widely, this is an area where many businesses accidentally fall out of compliance.
Corporate Tax Nexus and Business Registration
Hiring employees in a new state may require your business to register as a “foreign entity.” This does not mean international; it simply refers to doing business in a state where you weren’t originally formed.
Foreign registration usually involves:
● Filing paperwork with that state’s business division
● Paying registration fees
● Maintaining an in-state registered agent
Some states require annual reports once you register. Others have franchise taxes or minimum business taxes you must pay regardless of profit. Even if you have no customers in that state, the presence of an employee may be enough to create tax nexus.
Local Taxes Add Another Layer
Local taxes can be easy to overlook because not all states impose them. Cities like New York, Philadelphia, and San Francisco have local income taxes that employers are required to withhold. Some counties also have their own rates. If your employee works in a jurisdiction with local taxes, you may also need to register there.
Remote Workers Can Affect Your State Income Taxes
When an employee relocates, that state may attempt to tax part of your company’s income. This varies by state and depends on how each state defines corporate income apportionment. In some states, the physical presence of even one employee creates the right to tax a percentage of your company’s income. This can affect your annual state filings and increase tax preparation costs.
What Business Owners Can Do to Stay Compliant
1. Track where every employee physically works
2. Register early rather than waiting
3. Update payroll systems for each state
4. Keep an eye on remote-work legislation
5. Work with a tax professional familiar with multi-state compliance
