When expanding your workforce across U.S. states or hiring remote employees in different jurisdictions, one of the most critical challenges is EOR compliance.

In this guide, we’ll walk through what “EOR compliance” means in the U.S., key legal pitfalls, best practices, and how HireArt can help ensure you stay on the right side of the law.

What Is EOR Compliance?

“EOR compliance” refers to the legal, regulatory, and administrative obligations that must be met by an Employer of Record (EOR) and its client when employees are engaged under that arrangement. 

An EOR is a third-party entity that becomes the legal employer of workers on behalf of another company, handling payroll, taxes, benefits, and compliance with labor laws, while the client retains day-to-day control of work, projects, and performance. 

In the U.S., EOR compliance covers both federal and state regulations, which can vary widely by jurisdiction. Some of the core compliance domains include:

  • Employment eligibility and I-9 / E-Verify

  • Wage and hour laws (minimum wage, overtime, predictive scheduling)

  • Payroll tax withholding, reporting, and unemployment insurance

  • Workers’ compensation

  • Employee benefits and leave (e.g. FMLA, state family leave laws)

  • Worker classification (employee vs. independent contractor)

  • Notice, wage statements, and record keeping

  • Terminations, severance, and final pay

  • Local laws and ordinances (city or county mandates)

An EOR is expected to assume many of these responsibilities on behalf of the hiring company, but clarity regarding responsibility allocation is crucial.

Why EOR Compliance Matters in the US

1. Complexity across states. U.S. federal laws set minimum standards, but states and even localities can impose stricter requirements. For example, states may mandate additional leave, unique pay frequency rules, or overtime thresholds more generous than the federal standard.

2. Worker misclassification risk. Misclassifying a worker as an independent contractor instead of an employee can lead to back taxes, penalties, and lawsuits. An EOR should help guide proper classification. 

3. Liability and risk mitigation. If an EOR is truly acting as the legal employer, it can protect the client from certain compliance risks, shifting the burden of regulatory responsibility. 

4. Scalability and speed. When entering new states or hiring in places where your company doesn’t already have a legal entity, leveraging an EOR with compliance infrastructure helps you scale faster while mitigating legal risk.

Key U.S. Compliance Areas in Depth

Employment Eligibility & I-9/E-Verify

Under federal law, all U.S. employees must complete Form I-9 to verify identity and eligibility to work. Some employers (e.g. federal contractors) or states may also require use of E-Verify. An EOR must maintain properly completed I-9 records and comply with audit requests.

Wage & Hour Laws

The Fair Labor Standards Act (FLSA) is the baseline, but many states have higher minimum wages or stricter overtime triggers. EORs must ensure that pay, overtime, record keeping, and break/rest rules comply with applicable state law.

Payroll Taxes & Reporting

An EOR must withhold and remit federal income tax, Social Security, Medicare, and relevant state and local taxes. It must file quarterly and annual returns (e.g. Form 941, Form W-2s) and handle unemployment insurance contributions.

Workers’ Compensation & Unemployment Insurance

Each state has unique workers’ compensation and unemployment insurance systems. The EOR must register appropriately, pay premiums, and manage claims in compliance with state regulations.

Benefits, Leave & Protections

Federal laws like FMLA and ADA apply, and states may have additional leave laws (e.g. paid sick leave, paid family leave). EORs must integrate these into benefits administration and ensure employee rights are honored.

Termination & Final Pay

EOR compliance also extends to lawful termination, final pay deadlines, severance (where required), and any mandated notices (e.g. WARN Act). Some states demand immediate payment of all wages owed at termination.

Shared Responsibilities: What the Client vs. the EOR Must Handle

Even with an EOR, not all compliance tasks can or should be handed off. Clear delineation matters.

Responsibility
EOR’s Role
Client’s Role / Oversight
Legal employment status & contract
Draft and maintain compliant contracts

Run payroll, remit taxes, file reports
Fund payroll, provide compensation data
Benefits, insurance, leaves
Administer benefits, leave compliance
Determine benefit strategy
Worker classification guidance
Advise on classification
Provide job duties, control
I-9 / employment eligibility
Maintain I-9, E-Verify if applicable
Provide onboarding data
Performance management, daily work
No
Full responsibility
Termination compliance
Execute termination in line with the law
Initiate termination, inform EOR

Common Compliance Pitfalls & How to Avoid Them

  1. Ignoring state-specific laws — assuming federal law suffices.

  2. Misclassifying workers — e.g. labeling someone “contractor” when control, hours, or expectations align with employee status.

  3. Overlooking city-level ordinances — cities like San Francisco, Seattle, or New York may impose local mandates.

  4. Delays or errors in payroll/tax filing — missing deadlines risks penalties.

  5. Inadequate I-9 / E-Verify record maintenance — audits of I-9 files can be triggered by ICE.

  6. Failing to incorporate new leave laws — e.g. state paid family leave programs.

  7. Ambiguous agreement scopes — poor delineation can lead to liability disputes between company and EOR.

Best practices include: regular audits of compliance protocols, updating contracts when laws change, employing legal counsel in key states, and choosing an EOR with strong compliance track record.

Compliance to Improve Employee Experience

t HireArt, we believe compliance isn’t just about risk mitigation—it’s about trust. A compliant, W-2 employment experience helps workers feel valued, supported, and secure. When compliance works well, it actually improves worker satisfaction, retention, and performance.

Here’s how:

1. W-2 Status Means Greater Stability and Benefits

Unlike 1099 arrangements, W-2 employment ensures workers receive steady paychecks, tax withholdings handled on their behalf, and eligibility for benefits such as health insurance, PTO, and retirement plans. This creates real security for professionals working on long-term projects—a theme we’ve discussed in our article “Why Compliance Is the Foundation of a Better Contractor Experience.”

2. Transparent Pay and Protections Build Trust

From overtime pay to paid sick leave, compliant employment ensures workers are fairly compensated and protected under law. Creating predictable processes and consistent policies make workers feel safe and respected. This is the secret key to building engagement across contingent teams.

3. Legal Protections Promote Equity

Compliance brings parity between contract and full-time workers. It eliminates gray areas that often lead to unequal treatment in pay or opportunity. By using an EOR like HireArt that adheres to strict wage-and-hour and anti-discrimination standards, companies demonstrate their commitment to fairness and inclusion.

4. Consistency Across States Enhances Experience

A consistent employment experience—regardless of where workers are based—helps teams feel unified.

5. Compliance as a Cultural Advantage

Finally, compliance can actually elevate your brand. Workers talk, and reputation spreads. When contractors know they’ll be paid accurately, receive clear documentation, and access the benefits they deserve, your company becomes an employer of choice—especially in the competitive AI, tech, and professional contracting markets HireArt serves.
