Remote and hybrid work have become a permanent part of the modern workforce. Many businesses are now hiring remote employees across state lines or allowing existing employees to relocate while continuing to work remotely.
While remote work provides flexibility and access to a wider talent pool, it can also create new payroll tax compliance requirements for employers. In particular, employers should understand how remote work affects:
- State income tax withholding
- State unemployment insurance (UI) taxes
Because these rules are largely based on where an employee physically works, even a single remote employee in another state may create additional payroll tax obligations.
Below is an overview of how state withholding and unemployment taxes typically apply to remote employees.
State Income Tax Withholding for Remote Employees
In most cases, employers are required to withhold state income tax based on the state where the employee performs their work, not necessarily where the employer’s office is located. For example:
- A company headquartered in Texas hires a remote employee who lives and works in Colorado.
- Even though the employer is located in Texas, the employer may need to register for Colorado payroll withholding and withhold Colorado income tax from that employee’s wages.
Similarly, if an employee moves to another state while working remotely, the employer may need to update payroll withholding beginning on the date the employee starts working in the new state.
Reciprocal Agreements Between States
Some states have reciprocity agreements that allow employees who live in one state but work in another to pay tax only in their state of residence.
In these cases, the employee may provide documentation allowing the employer to withhold tax only for the home state rather than the work state.
However, reciprocity agreements are limited and only apply to certain state pairs, so employers should confirm whether an agreement applies before relying on this rule.
Employer Registration Requirements
If a remote employee triggers withholding requirements in a new state, employers may need to:
- Register for a state payroll withholding account
- File periodic withholding tax returns
- Remit withheld taxes to the state
- Report wages on state-specific W-2 filings
Because each state has its own payroll tax rules and filing requirements, employers should review these obligations before hiring employees in a new state.
Unemployment Insurance (UI) Taxes for Remote Employees
State unemployment insurance taxes follow a different set of rules than state income tax withholding.
Instead of being based solely on where an employee works, unemployment taxes are determined using federal “localization of work” rules, which help determine which single state receives the employer’s unemployment tax contributions.
Generally, the determination follows this order:
1. Localization of Services
If most of the employee’s services are performed in one state, that state will typically receive the unemployment tax.
2. Base of Operations
If the employee works in multiple states but operates from a base in one state, unemployment tax may apply to that state.
3. Place of Direction & Control
If the employee’s work is directed or managed from a particular state, that state may determine where unemployment taxes are paid.
4. Employee’s State of Residence
If none of the previous rules apply, unemployment taxes may default to the employee’s home state. Unlike income tax withholding, unemployment insurance tax is typically paid to only one state per employee.
Additional Compliance Issues for Employers with Remote Workers
Beyond withholding and unemployment taxes, remote employees can create other state compliance considerations for employers. For example, having employees working in another state may trigger:
- State business registration requirements
- Local payroll taxes
- State labor law compliance
- Workers’ compensation coverage in the employee’s state
- Potential state tax nexus issues
Because state laws vary widely, employers should evaluate these requirements whenever employees begin working in a new location.
Best Practices for Managing Payroll Taxes for Remote Employees
Employers with remote or multi-state employees may want to consider several best practices to help reduce compliance risks:
- Track where employees are physically working
- Require employees to notify management before relocating
- Update payroll systems when employees move to another state
- Confirm state withholding requirements before hiring in a new state
- Periodically review payroll setup for multi-state compliance
Taking these steps early can help prevent unexpected payroll tax issues later.
