Why Remote Work Creates Multi-State Legal Obligations

When an employee performs work from their home in a particular state, that state's employment laws apply to that employee. The employer's physical location is irrelevant for most purposes. This means a company headquartered in Texas with remote employees in California, New York, and Illinois is effectively operating under four separate sets of employment laws simultaneously.

The obligations triggered by a remote employee in a new state include: registering as a foreign entity doing business in that state, withholding state and local income taxes, paying state unemployment insurance, complying with that state's wage and hour laws (including its own minimum wage and overtime rules), providing all legally required notices and postings, maintaining workers' compensation coverage, and adhering to that state's leave laws, anti-discrimination laws, and any other employment regulations.

The cost and administrative complexity of operating in a new state are real and should factor into hiring decisions. Before approving a remote hire — or a remote employee's relocation — HR should assess the full compliance cost of establishing a legal presence in the new state.

The Hidden Cost of Unvetted Remote Hires

Hiring a remote employee in California without proper registration creates retroactive tax liability, potential penalties, and subjects the employer to California's expansive employment law — including strict overtime rules, meal and rest break requirements, expense reimbursement mandates, and enhanced discrimination protections. A single unvetted hire can create years of back-compliance obligations.

Pre-Hire Compliance: What to Do Before an Employee's First Day

For remote employees in states where the employer has not previously operated, the pre-hire compliance workflow should include:

  • State registration: Register with the Secretary of State as a foreign entity (if required) and obtain an Employer Identification Number with the state tax authority.
  • Payroll setup: Configure state and local income tax withholding and unemployment insurance contributions for the employee's home state.
  • Workers' compensation: Obtain coverage in the employee's state or confirm that existing coverage extends to that state.
  • Required notices: Identify and provide all required new hire notices for the employee's state. These vary significantly — California, for example, requires multiple specific notices at hire.
  • Policy review: Review the employee's offer letter and employment terms against the new state's requirements — particularly around at-will employment, non-competes, expense reimbursement, and leave.

Ongoing Compliance Obligations for Remote Workers

Compliance does not end at onboarding. Ongoing obligations for remote employees include:

Remote Work Compliance: Ongoing Obligations by Category

Payroll: apply correct state/local tax rates and withholding rules. Wage and hour: apply the higher of federal, state, or local minimum wage; apply state overtime rules (California requires daily overtime, for example). Leave: track and administer FMLA plus any applicable state leave programs. Benefits: ensure benefits comply with state requirements (some states mandate certain benefits or restrict plan design). Workplace notices: maintain required posters for the employee's state in digital or physical form. Workers' comp: maintain current coverage certificates.

Expense Reimbursement: A Commonly Overlooked Obligation

Several states require employers to reimburse employees for necessary work-from-home expenses. California is the most notable — Labor Code Section 2802 requires employers to indemnify employees for all "necessary expenditures" incurred in performing their duties. This can include a portion of internet service, cell phone use, home office equipment, and other work-related costs.

Illinois, Seattle, and other jurisdictions have similar requirements. Employers who fail to reimburse required expenses may face wage claims, and the damages can be substantial when multiplied across a remote workforce over several years. Review your expense reimbursement policy against the requirements of each state where you have remote employees.

Building a Remote Work Policy That Protects You

Every remote worker should have a signed remote work agreement that documents: approved work location, restrictions on working from other locations, equipment ownership and return requirements, data security obligations, applicable state law, and expense reimbursement terms. Using an ATS like Treegarden to track employee locations and documentation status helps ensure nothing slips through the cracks as your distributed workforce grows.

Managing Employee Relocations and Location Changes

Employee-initiated relocations are one of the most common sources of unexpected compliance risk. An employee who moves from Ohio to Colorado without formal approval — and without the employer's knowledge — creates Colorado compliance obligations retroactively from the date the move occurred.

Establish a formal pre-approval process for any change in an employee's work location. The policy should require employees to notify HR before moving to a new state or working remotely from a different location for more than a threshold number of days. Define what approval is required and document the decision. If the relocation creates significant new compliance costs, the employer may need to either absorb them or discuss a compensation adjustment with the employee.

Technology Tools That Support Remote Work Compliance

Managing multi-state compliance manually at scale is effectively impossible. Technology tools are essential. HRIS systems should maintain accurate, real-time employee location data. Payroll systems must support multi-state withholding. Document management systems should track which notices each employee has received. ATS platforms like Treegarden help ensure that remote hiring workflows include the necessary compliance steps before day one — reducing the risk that a new remote hire triggers overlooked state obligations.

Invest in regular audits of your technology stack to confirm that employee location data is accurate and that payroll, benefits, and leave administration reflect each employee's actual work state.

Frequently Asked Questions

Does hiring a remote employee in another state create a business presence there?

Yes, in most cases. A remote employee working from a state typically creates nexus — a taxable presence — in that state for the employer. This triggers obligations to register as a foreign business entity, withhold state income taxes, pay unemployment insurance contributions, comply with that state's employment laws, and potentially pay state corporate income tax. Consult a multi-state tax attorney before hiring in a new state.

Which state's employment laws apply to a remote employee?

Generally, the laws of the state where the employee physically performs work apply to that employee. This includes wage and hour laws, leave laws, anti-discrimination protections, and workers' compensation requirements. If an employee is based in California, California law applies to their employment — regardless of where the employer's headquarters is located. Some states have reciprocity agreements for tax withholding but not for substantive employment law.

How should employers handle remote employees who want to relocate?

Establish a formal remote work relocation request process. When an employee requests to relocate, assess the compliance obligations the new state would create before approving. Consider the cost and administrative burden of operating in a new state, whether the role can legally be performed there, and any compensation adjustments warranted by cost-of-living differences. Document the approval, update all HR systems, and notify payroll immediately.

What are the biggest compliance mistakes with remote employees?

The most common mistakes are: failing to register in the employee's home state before their start date; using the headquarters state's minimum wage instead of the employee's state minimum wage; not applying the correct state's leave laws; sending required workplace notices (like FMLA) appropriate to the headquarters state rather than the employee's state; and failing to maintain workers' compensation coverage in the employee's state.

Do remote employees need separate written employment agreements?

A remote work policy or addendum is strongly recommended and, in some situations, legally required. It should document the employee's approved work location, any restrictions on working from other locations, equipment and expense reimbursement terms, data security requirements, and the applicable state law. When employees work across state lines regularly (like commuters), the agreement should address which state's law governs and how taxes are handled.
