Payroll nexus

What is payroll nexus?

Payroll nexus is the tax obligation created in a state because you have an employee working there. Hiring one remote person in a new state typically triggers employer registration, state income tax withholding, unemployment insurance, and sometimes local taxes. Unlike revenue thresholds, payroll nexus often starts with a single employee and a single day of work. For firms that hired remotely during growth, this is the most common hidden compliance gap.

What one remote hire actually requires

You generally need a state withholding account, a state unemployment account, and sometimes registration with the secretary of state. Workers compensation coverage must extend to that state. Some cities add their own payroll taxes. Your payroll provider can file once accounts exist, but someone has to open them, and that someone is usually you or your accountant. Paid family leave programs in several states add another registration and another rate.

Where it spreads beyond payroll

An employee in a state can also create income tax nexus for the firm itself, pulling you into apportionment and a new income tax return. A remote salesperson almost always does. Even a fully remote administrative employee can be enough in some states. Tell your accountant before you make an out-of-state hire, not after the first paycheck clears. Retroactive registration with penalties costs far more than doing it in order.
