Hiring in the United States: What International Employers Need to Know

Companies typically choose between an Employer of Record for first hires or a small footprint, in-country payroll management once a US entity exists, and full entity setup once headcount and state coverage justify direct ownership. The right route depends heavily on how many states you plan to employ in, expected headcount, and how quickly you need to start paying people compliantly.

Employer of Record in the United States

An EOR is the fastest way to legally employ staff in the US without incorporating first, and it is especially useful for testing a state before committing to it. Because employment law, payroll tax registration, and workers' compensation requirements are set at the state level, an EOR that already holds registrations across multiple states removes a real operational burden — you are not filing new state tax accounts every time you hire in a new location. This makes EOR a strong fit for companies making their first US hires, hiring senior individual contributors ahead of a broader build-out, or testing a specific state market without long-term commitment. It is a weaker fit once you have significant, concentrated headcount in one or two states and want direct control over benefits design and equity administration.

How payroll works in the United States

US payroll runs on a dual federal-and-state system. At the federal level, employers withhold federal income tax and FICA (Social Security and Medicare) from employee pay, and separately owe federal unemployment tax (FUTA). At the state level, most states layer on state income tax withholding, state unemployment insurance (SUTA), and in some cases additional payroll-related levies (paid family leave contributions, disability insurance, or local payroll taxes in specific cities). Pay frequency is employer-determined within state limits — biweekly and semi-monthly are the most common cycles for salaried staff, with weekly cycles more common in hourly and blue-collar roles. Employers must register for a federal EIN and separate state tax and unemployment accounts in every state where they have employees, and new-hire reporting to the state is mandatory within a short window of the hire date.

Payroll frequency and reporting obligations

Pay frequency rules vary by state — some states mandate a minimum frequency (e.g. weekly or biweekly for certain worker categories), so a national pay calendar has to respect the strictest applicable state rule. Federal reporting includes quarterly Form 941 filings and annual W-2/W-3 filings for employees (1099-NEC for contractors). At the state level, employers file quarterly wage and unemployment reports and annual reconciliations, and many states require electronic payslip access showing itemised deductions. New-hire reporting to a state new-hire registry is required within days of the start date in most states, feeding child-support enforcement databases. Getting this wrong is one of the more common compliance gaps for foreign employers entering the US without local payroll expertise.

Key payroll nuances

There is no federal 13th-month or mandatory bonus requirement — bonus and variable pay structures are entirely at employer discretion, which gives international employers latitude but also means expectations vary sharply by industry and seniority level. Overtime is federally mandated under the Fair Labor Standards Act (FLSA) at 1.5x pay after 40 hours per week for non-exempt employees, and several states have stricter daily-overtime or double-time rules (notably California). Final pay timing on termination is state-specific and in some states is required within 24 hours or the next business day — far stricter than most countries. Direct deposit is standard but cannot usually be mandated without an employee opt-out option in many states, so payroll systems need to support paper-check fallback.

Pay components and employer costs

Beyond base salary, typical pay components include overtime for non-exempt roles, discretionary or performance bonuses, commission for sales roles, and equity for many white-collar and tech positions. Employer costs on top of salary include the employer share of FICA (Social Security and Medicare), FUTA and SUTA unemployment contributions, workers' compensation insurance premiums (mandatory in nearly all states), and, in some states, additional payroll levies for paid family or medical leave. Health insurance is not government-mandated for all employers but is a de facto requirement for competitive hiring, and larger employers face Affordable Care Act coverage obligations. All-in employer costs on top of base salary typically add somewhere in the range of 20 to 35 percent depending on benefits generosity and state.

Benefits and leave entitlements

The US is unusual among large economies in having no federal mandate for paid annual leave, paid sick leave, or paid parental leave — these are set by a patchwork of state and city laws, or offered voluntarily by employers to stay competitive. Many states and cities mandate paid sick leave accrual; a smaller but growing number mandate paid family leave funded through payroll contributions. Federally, the Family and Medical Leave Act guarantees unpaid, job-protected leave for qualifying employees at larger employers, but pay during that leave depends on state programs or employer policy. Health insurance is the benefit employees expect most, and most competitive employers offer it even though it is not universally mandated. Public holidays are also employer-discretionary at the federal level, though most companies observe 10 to 11 standard days.

Hiring and employment contracts

Most US employment is "at-will," meaning either party can end the relationship at any time without cause, subject to anti-discrimination and contractual exceptions — this is a significant structural difference from most European and APAC markets and should be explained clearly to first-time entrants. Written contracts are common for senior roles and equity-holding employees but not legally required for most positions; offer letters are the norm. Probation periods are used informally rather than as a statutory concept. Worker classification — employee versus independent contractor — carries real audit and back-tax risk, and misclassification is one of the most common compliance issues international employers encounter when engaging US talent informally.

Entity setup in the United States

Foreign companies most commonly set up either a Delaware C-Corporation or an LLC, with Delaware, and to a lesser extent states like California, Texas, and New York, being common incorporation choices depending on where operations and hiring will concentrate. Incorporation itself can be completed within days through a registered agent, but the real timeline driver is obtaining a federal EIN, registering as a foreign entity ("qualifying to do business") in every state where you will have employees, opening a US bank account (which increasingly requires an in-person or verified process), and completing state tax and unemployment registrations before running payroll. Typical end-to-end setup, including all registrations needed before a first payroll run, takes four to eight weeks depending on the states involved and banking requirements.
