What Hawaii Businesses Need to Know About Out-of-State Employees

As you begin to explore becoming a multi-state employer, the compliance side of things isn't always straightforward. When you have an employee in another state, you're responsible for that state's employment laws, tax requirements, and benefit mandates from day one. The rules vary a lot, and some of the most common mistakes are easy to make without realizing it.

Here's a practical breakdown of what to know before you make that first out-of-state hire:

#1. Every state has its own employment laws, and they apply to your employees from day one

One of the most common misconceptions Hawaii employers have is that their existing HR policies and practices will carry over when they hire in a new state. They won't. Employment law is largely governed at the state level, and the rules vary dramatically across the country. In some cases, they vary by city or county.

State-specific laws affect nearly every aspect of the employment relationship: minimum wage and overtime requirements, final paycheck timing, required leave, anti-discrimination protections, required workplace notices, and more. Missing a required policy or benefit program can result in government fines, employee complaints, or other legal exposure.

One of the most frequent errors Hawaii employers make is continuing to file a remote employee's payroll taxes in Hawaii after they've relocated. If your employee lives and works in California, their payroll taxes must be filed in California. Getting this wrong means corrections with multiple state agencies, potential penalties, and a time-consuming process to unravel. It's exactly the kind of issue that's easy to avoid with the right partner in place from the start.

#2. You must register your business in each state where you have employees, unless you work with a PEO

The moment you have an employee working in another state, you've established what's called “nexus” in that state, which triggers a series of registration and compliance obligations. At minimum, you'll typically need to register with that state's department of labor, set up a state withholding account, and register for state unemployment insurance (SUTA).

Here's where it gets more nuanced. In 27 “PEO reporting states,” companies that work with a PEO can skip this step entirely. In these states, the PEO uses its own tax rate and account to calculate and file your state unemployment taxes, so there's no need to register your business or open your own unemployment account separately. This means you can hire and onboard employees faster.

In the remaining 23 “client reporting states,” you must register your business and obtain your own SUTA account before a PEO can process payroll on your behalf. Registration looks different in every state. In some it's a single online application, in others it's a multi-step process that starts with the Secretary of State's office. If you're operating in a client reporting state, looping in your CPA and corporate advisors early will help the process move smoothly.

#3. State-mandated benefits vary widely, and your current setup may not cover your mainland employees

Workers' compensation alone illustrates how complicated this gets. Every state requires it, but four states (Ohio, North Dakota, Washington, and Wyoming) operate as monopolistic states, meaning private insurers aren't permitted to sell coverage there. In those states, you must obtain a workers' comp policy directly from a state-run fund before your employee's first day.

Beyond workers' comp, paid family and medical leave (PFML) is expanding. As of 2026, 14 states and Washington D.C. have mandatory PFML programs, covering an employee's own medical condition, bonding with a new child, caring for a seriously ill family member, and other qualifying purposes. What's covered, who's eligible, and how the benefit is funded varies by state. When you work with a PEO, contributions are calculated and remitted as part of your regular payroll process, but you still need to know the requirements apply.

One important note for Hawaii employers: Hawaii's Temporary Disability Insurance (TDI) is Hawaii-specific. Out-of-state employees aren't eligible for TDI. If your employees are located in California, New Jersey, New York, or Rhode Island, that state's own disability program will apply instead.

Healthcare is another consideration. Sourcing health plans state by state can be complex, and coverage options vary significantly across the country. One of the key advantages of working with a PEO is the ability to offer consistent, quality health coverage across all 50 states without having to source plans individually.

Building a stronger Hawaii workforce, wherever your team lives

Becoming a multi-state employer is one of the most effective ways Hawaii businesses can fight brain drain, retain their best people, and access a wider talent pool. The compliance, registration, and benefits complexity is real, but it's much more manageable with the right partner.
