Hiring in the United States: EOR Guide & Compliance Overview

Overview

If you are hiring your first 1-10 employees in United States, using an EOR is usually the lowest-risk option because onboarding often starts in 2-6 weeks, while entity setup can take several months.

The US has no single employment law, it has 50 of them, plus federal statutes layered on top. Employer costs are lower than most of Europe (no mandatory severance, limited statutory benefits), but the compliance complexity is in the patchwork: California’s meal-break rules differ from New York’s wage-theft protections, which differ from Texas’s at-will framework. Health insurance isn’t statutory, but failing to offer it makes you uncompetitive for any skilled hire.

This framework is strongest when combined with vendor comparisons, hiring demand by country, and clear definitions from the EOR glossary.

Foreign companies use a US EOR to skip the entire entity setup process. Without one, you need a US legal entity (LLC or C-Corp), an EIN from the IRS, state-level employer registrations in every state where you have workers, and a registered agent in each of those states. That’s 4–8 weeks of legal work and $5,000–$15,000 in formation and compliance fees before you’ve made a single hire. An EOR eliminates all of it. You sign a service agreement, the EOR’s entity becomes the legal employer, and your hire starts in days.

Three states drive most of the regulatory headaches. California layers its own overtime rules (daily overtime after 8 hours, not just weekly), mandatory meal and rest breaks with penalty pay for violations, and the strictest worker classification standards in the country under AB 5. New York adds the WARN Act at 25 employees (versus 100 federal), predictive scheduling laws in New York City, and aggressive wage-theft enforcement. Massachusetts requires earned sick time accrual from day one and has its own paid family and medical leave program funded by payroll contributions. If your first US hires are in any of these states, an EOR that handles state-specific compliance well isn’t optional, it’s the whole point.

Key Employment Facts

Statutory Benefits

Federal law requires very little: Social Security and Medicare contributions, unemployment insurance, workers’ compensation (state-mandated), and FMLA leave (unpaid, for employers with 50+ employees). There is no federal paid vacation, no federal paid sick leave, and no federal paid parental leave.

COBRA adds a post-employment obligation that catches some foreign employers off guard. When an employee leaves or loses coverage, the employer (or EOR) must offer 18 months of continued health coverage at the employee’s expense plus a 2% admin fee. The employer doesn’t pay the premium, but administering the notice requirements incorrectly triggers penalties of $110 per day per affected individual. For employers with 50 or more full-time employees, the ACA’s employer mandate also kicks in: you must offer affordable minimum-essential health coverage or face penalties of $2,970 per full-time employee per year (2025 figure). Most EOR entities are large enough to trigger this threshold, so your EOR should already be ACA-compliant.

State laws fill some gaps, and more are adding them every year. California mandates paid family leave (up to 8 weeks at 60–70% of wages) and state disability insurance. New York requires paid family leave (up to 12 weeks at 67% of average weekly wage) and short-term disability. Washington mandates paid family and medical leave funded by shared employer-employee premiums. Massachusetts, Connecticut, and Oregon have each launched their own paid leave programs since 2021. If you’re hiring across multiple states, the leave entitlements differ enough that tracking them manually is a compliance trap.

The practical floor for competitive US employment includes health insurance, dental, vision, 401(k), and 2–4 weeks PTO. None of these are legally required federally, but all of them are expected by any candidate worth hiring. Skip health insurance and you lose the offer. Skip 401(k) matching and your retention drops. This is the gap EOR providers fill: they bundle benefits packages that meet market expectations so a foreign company doesn’t have to negotiate group health plans or set up retirement accounts independently.

Work Visas and Immigration

Foreign worker sponsorship in the US is one of the most complex and expensive immigration systems globally. Many EOR hires are local residents or existing visa holders, but for companies that need to relocate talent, the process demands planning months in advance.

EOR providers can sponsor work visas as the petitioning employer, but this is where it gets complicated. For H-1B petitions, the EOR’s entity must be the employer of record and demonstrate a legitimate employer-employee relationship — USCIS scrutinizes staffing-like arrangements. The H-1B lottery has a roughly 25–30% selection rate, meaning most first-time registrations don’t get picked. L-1 visas don’t apply to standard EOR setups because they require a qualifying corporate relationship between the foreign and US entities. O-1 visas are employer-agnostic and work well through an EOR, but the evidentiary bar for “extraordinary ability” is high.

The prevailing wage requirement applies to all sponsored employment-based visas. The EOR must pay at least the Department of Labor’s prevailing wage for the occupation and location, which in high-cost metros like San Francisco or New York can set a salary floor above what you’d planned. Immigration legal fees run $5,000–$15,000 per visa petition on top of USCIS filing fees. Not all EOR providers handle immigration in-house — some partner with external firms, adding coordination overhead. If visa sponsorship is a core part of your US hiring strategy, confirm your provider’s immigration capabilities before signing.

Top EOR Providers for United States

Rippling runs US payroll natively and offers the deepest integration for domestic HR operations. Deel provides all-50-states EOR coverage with fast onboarding (1–3 days). Remote operates through its owned US entity, appealing for compliance-sensitive employers. Pebl (formerly Velocity Global) adds value when US hiring involves immigration complexity.

Pricing for US EOR runs $500–$700/month per employee with most providers. Rippling stands apart because it’s both an HR platform and an EOR: if you later set up your own US entity, you can migrate employees off EOR onto Rippling’s direct payroll without switching systems. Deel onboards fastest (often same-day for straightforward hires), which matters if you have a signed candidate waiting. Remote’s owned-entity model means no third-party partners sit between you and the legal employer, a selling point for companies with strict IP or data requirements. For multi-state compliance specifically, Rippling and Deel handle the patchwork best because they’ve built automation around state tax registration, local withholding, and jurisdiction-specific reporting.

Employer Cost

Federal statutory employer costs are low — but health insurance and 401(k) matching make the real total significantly higher.

Federal payroll taxes: Social Security (FICA) at 6.2% on wages up to $176,100 (2025 wage base) + Medicare at 1.45% with no cap. Total: 7.65% up to the SS wage base, 1.45% above it.

State unemployment insurance (FUTA/SUTA): Federal FUTA: 0.6% on first $7,000 (effectively $42/employee/year after credits). State rates vary dramatically: 0.1–5.4% depending on the employer’s experience rating and state. California’s maximum rate reaches 6.2% on $7,000; Texas is 2.7% on $9,000.

Workers’ compensation: State-mandated and procured from state funds or private insurers. Rates vary by occupation and state: office roles in Texas might cost $0.10–$0.50 per $100 of payroll; construction in California can reach $5–$15 per $100. The EOR’s experience modification rate affects the actual cost.

Market-essential benefits (not legally required but functionally mandatory): Health insurance for a competitive candidate: employer covers 70–80% of the premium — approximately $5,000–$12,000/year per employee depending on plan tier, family status, and state. 401(k) match at 3–6%: $3,600–$7,200/year for a $120,000 salary.

Total employer cost above salary for a $120,000 tech hire in California: FICA ~$9,180, FUTA/SUTA ~$500–$1,500, workers’ comp ~$600, health insurance ~$8,000, 401(k) match ~$4,800, EOR fee ~$7,200. Total: approximately $30,000–$31,000 above gross salary, or 25–26%. Budget 25–35% above base salary for a fully loaded US employee with competitive benefits.

Termination Rules

At-will employment is the default in 49 states (Montana is the exception post-probation). Either party can end the employment relationship at any time, for any reason, without notice — unless the contract specifies otherwise.

What at-will doesn’t permit: Termination for discriminatory reasons (race, sex, age, disability, religion, national origin, pregnancy under Title VII, ADEA, ADA), in retaliation for protected activities (filing an EEOC complaint, taking FMLA leave, whistleblowing), or in violation of public policy (refusing to commit a crime, serving on a jury). These restrictions have no qualifying period and no cap on damages.

State exceptions: California’s Tameny wrongful discharge doctrine, implied contract exceptions in multiple states, and covenant of good faith exceptions in California and a handful of others extend employee protections beyond the federal baseline. In California specifically, the WARN Act applies at 75 employees (versus 100 federal), plant closure rules are stricter, and final pay must be issued immediately on termination (versus the next scheduled pay date in most states).

Severance: No federal requirement. Market practice is 1–2 weeks per year of service, negotiated as a condition of signing a separation agreement and release. The release is the employer’s primary protection against future claims — and it’s only enforceable if the employee had time to review it (21 days, 45 days if part of a group layoff) and a 7-day revocation period under the ADEA for employees over 40.

WARN Act (Worker Adjustment and Retraining Notification Act): For employers with 100+ full-time employees: 60 days’ advance written notice required for mass layoffs (50+ employees at a single site) or plant closings. Failure triggers liability of up to 60 days’ pay and benefits per affected employee. State mini-WARN laws (California, New York, New Jersey) lower these thresholds significantly.

Budget: final paycheck (includes all accrued, unused PTO in states where PTO vests, such as California), COBRA administration obligations, and any negotiated severance package. Most clean exits cost 0–4 weeks’ salary unless voluntary severance is offered.

Frequently Asked Questions

What are the real employer costs beyond salary in the US?

Budget for 7.65% in payroll taxes (Social Security + Medicare), 0.5–5.4% for state unemployment insurance, $500–$5,000/year for workers’ compensation (varies dramatically by state and role), and $6,000–$15,000/year for health insurance if you’re offering it. Total employer burden is typically 20–30% above base salary when benefits are included.

Can I hire in any US state through an EOR without registering there?

Yes, that’s the primary value of US EOR. The EOR entity is the registered employer in each state, handling state tax withholding, new hire reporting, and local compliance. You don’t need to register your company in any state. This is particularly valuable for foreign companies with no US legal presence.

Is at-will employment really as simple as it sounds?

Simpler than most international markets, but not without risk. At-will means either party can end employment without cause or notice. However, you still can’t terminate for discriminatory reasons (Title VII, ADA, ADEA), in retaliation for protected activities, or in violation of implied contracts. Montana is the only state that requires cause for termination after a probationary period. In practice, documenting a performance trail before terminating reduces litigation risk, even in at-will states.

What benefits do I need to offer to be competitive for US tech talent?

More than the law requires. Federal statutory benefits are almost nothing, but the market demands a full package. Health insurance is the non-negotiable: competitive employers cover 70–80% of the monthly premium, which means the employer pays $5,000–$12,000/year per employee depending on plan tier and state. A 401(k) with 3–6% employer match is table stakes for any engineering or product role. Below 3% match, candidates notice. PTO of 15–20 days per year is standard; unlimited PTO policies are common at startups but increasingly viewed skeptically by candidates who’ve seen them used to avoid payout obligations. Dental and vision coverage adds $500–$1,500/year per employee and signals that the benefits package isn’t an afterthought. Most EOR providers bundle these into their offering. Deel and Remote include benefits administration in their per-employee fee, while Rippling lets you customize plan options through its benefits marketplace. Budget 25–35% above base salary for the full cost of a competitively compensated US employee.
