The Tax Implications of Hiring an Out-of-State Employee

June 10, 2025 - 8 minutes read

Hiring employees from other states can be a strategic move, allowing your business to tap into a wider talent pool and grow geographically. But with this expansion comes a key consideration: tax implications. State tax laws vary widely, and having an employee in another state can impact your payroll, employer obligations, and overall compliance. Setting up your business to handle these requirements is crucial to avoid risks and unexpected costs. Here’s what you need to know.

Why Do State Taxes Matter?

When an employee works in a different state from where your business is physically located, you are likely to be subject to that state’s tax laws. This affects withholding taxes, unemployment insurance, and possibly other liabilities, such as income tax or sales tax nexus. Essentially, having employees in other states creates a “business presence” that holds your company accountable for specific tax responsibilities in that jurisdiction.

Key Tax Considerations

1. State Income Tax Withholding

Every state with an income tax requires employers to withhold taxes from employees’ wages and file them with the state tax authority.

  • Employer’s Role: You are responsible for registering your business with the tax authority in the state where your employee resides. Once you’re registered, you’ll need to set up payroll systems to comply with that state’s withholding rules and ensure remittance happens on time.
  • Reciprocity Agreements: Some states have reciprocity agreements that simplify withholding for employees who work in one state and live in another. These agreements allow employees to pay taxes only in their home state, saving businesses added hassle. Check whether the states involved in your situation have reciprocal agreements.

2. Unemployment Insurance Taxes

Unemployment insurance is a payroll tax typically paid by the employer into a state’s unemployment fund.

  • Which State Gets Paid? Unemployment taxes are generally determined by where the employee works rather than where the company is located. Each state has its own unemployment tax rate and wage base limits, and you’ll need to register with the appropriate state agency to begin contributions.
  • State Variance: Keep in mind that unemployment tax rates and maximum taxable wages vary. Be sure to review the requirements for the state in question to ensure compliance.

3. Workers’ Compensation Insurance

Workers’ compensation is not a tax, but it is required in almost every U.S. state to protect employees in the event of a work-related injury or illness.

  • State-Specific Rules: The workers’ compensation laws, requirements, and policies vary between states. If your new hire operates in another state, you’ll need workers’ compensation coverage that complies with that state’s laws.

4. State and Local Business Taxes

Bringing on an employee in a new state may create a “nexus,” or taxable presence, for your business. The rules for this vary depending on where your employee lives and works.

  • Income Tax Nexus: Some states interpret hiring even one out-of-state employee as establishing a taxable presence for corporate income tax purposes. This means you may be required to file a corporate tax return in that state, even if your business doesn’t otherwise operate there.
  • Sales Tax Nexus: If you sell goods and services, check whether having an employee in a given state triggers sales tax nexus. Some states consider this type of business presence sufficient to collect and remit sales tax for transactions in that state.

5. Local Taxes

Some areas levy local income taxes that employers must withhold and pay. For example, states like Ohio and Pennsylvania have numerous local tax jurisdictions. Be aware of city and county tax requirements that may apply based on your employee’s address.

6. Compliance When Hiring Remote Employees

Remote work has only grown in popularity, prompting new questions about how state tax and labor laws apply. Here’s what businesses must keep in mind when employing remote workers in other states:

  • Labor Laws: Beyond taxes, other employment laws vary by state, including wage-and-hour rules (minimum wage and overtime requirements), paid sick leave, and mandatory benefits.
  • Permanent Remote Work vs. Temporary Assignments: For employees who temporarily relocate, some states offer grace periods where taxes don’t need to be withheld. However, this period usually ranges from 30 to 90 days.

How to Set Your Business Up for Success

Navigating state tax requirements may feel daunting, but there are steps you can take to ensure your business remains compliant and ready to grow.

Register with State Authorities

Once you’ve identified the state where your new employee is based, you’ll need to register your business with that state’s tax and labor departments. This enables you to start withholding taxes, paying into unemployment insurance, and filing necessary returns.

Use a Robust Payroll System

A capable payroll platform makes it easier to manage multi-state employee payroll by automating calculations for various withholding and employer contributions. Look for systems with built-in compliance checks and multi-state functionalities.

Partner with an Accountant or Tax Professional

One of the best ways to avoid mistakes and penalties is by consulting professionals who specialize in multi-state tax compliance. A tax expert or payroll advisor will help ensure you’re covering all obligations, from filing deadlines to obtaining workers’ compensation policies.

Monitor for Changes

State tax laws can and often do change. Set up a system or partner with a service provider to monitor updates in states where your business operates to keep your compliance status intact.

Final Thoughts

Having employees in different states can certainly expand your company’s reach and capabilities, but it also comes with a set of tax implications that must be carefully managed. From income tax withholding to creating a nexus, each consideration plays a role in ensuring compliance and minimizing risk for your business.
