Multi-State Payroll: Where to Withhold When Employees Work Remotely

The Physical Presence Rule: The Default Standard

In the majority of jurisdictions, the primary rule for state income tax withholding is based on physical presence. You must withhold taxes for the state where the employee is physically located while performing the work, regardless of where the company’s headquarters is situated.

Failure to register in the employee's home state creates a 'nexus' for the business, triggering not only payroll tax obligations but potentially corporate income and sales tax liabilities.

1. Determine State Reciprocity Agreements

State reciprocity agreements allow employees who live in one state but work in another to pay taxes only to their state of residence. This simplifies payroll for businesses operating near state borders.

• Check the Agreement: If State A and State B have reciprocity, the employee submits a non-residency certificate (e.g., Form VA-4 in Virginia for Maryland residents).
• Withholding Action: You withhold taxes for the state of residence rather than the state of physical work.

2. The 'Convenience of the Employer' Rule

Five states (New York, Pennsylvania, Nebraska, Delaware, and Connecticut) currently enforce a 'Convenience of the Employer' rule. Under this rule, if an employee works remotely for their own convenience rather than out of necessity for the employer, the employer must withhold taxes for the employer's state, not the employee's remote location.

3. Unemployment Insurance (SUTA) and the Four-Part Test

Unlike income tax, SUTA (State Unemployment Tax Act) follows a specific four-part hierarchy established by the U.S. Department of Labor to ensure an employee is only covered by one state:

1. Localization: Is the service performed entirely in one state?
2. Base of Operations: If not localized, where is the employee's base of operations?
3. Place of Direction and Control: Where does the manager supervise the employee from?
4. Residence: If none of the above apply, use the employee’s state of residence.

4. Operational Compliance Checklist

To maintain compliance when hiring in a new state, follow these granular steps:

• Register for a Withholding Account: Apply for a state tax ID with the Department of Revenue.
• Register for SUTA: Apply for an account with the state’s Department of Labor or Unemployment Commission.
• New Hire Reporting: Submit the required new hire reporting forms to the state agency within 20 days of hire.
• Workers' Compensation: Ensure your policy covers the specific state where the remote employee resides.

Note: Thresholds for 'nexus' vary. Some states require withholding after a single day of work, while others (like Georgia or Maine) have specific income or time-based thresholds before withholding is triggered.
