The Complete Guide to Hiring in the U.S.: Federal vs. State Laws, Payroll Tax, and Compliance

Hiring in the United States is one of the most complex employment landscapes in the world — and most business owners, HR leaders, and global companies don't realize just how much they don't know until they're already in trouble. Whether you're a foreign company expanding into the U.S. for the first time, a fast-growing startup scaling across multiple states, or an established business trying to clean up compliance gaps, the rules are layered, unforgiving, and constantly evolving. This guide breaks everything down — from federal mandates to state-by-state quirks, payroll tax obligations, worker classification, benefits requirements, and how tools like Deel can save you from the legal and financial landmines hiding in plain sight.

Why Hiring in the U.S. Is More Complicated Than You Think

Most people assume that once you understand federal employment law, you understand U.S. hiring. That assumption is wrong — and it's expensive.

The United States operates under a dual-layer legal system where federal law sets the floor, and state (and sometimes local) laws can raise the ceiling dramatically. You might be fully compliant with federal rules and still face a lawsuit or penalty because you missed a California meal break requirement or a New York City salary transparency ordinance.

Here's what makes U.S. hiring uniquely challenging:

• 50 states, 50 different sets of employment laws — and some cities and counties add even more layers
• No single federal mandate for paid leave, making benefits obligations a patchwork of state-specific rules
• Multiple federal agencies — the IRS, Department of Labor (DOL), Equal Employment Opportunity Commission (EEOC), and more — each with their own enforcement powers
• Independent contractor vs. employee misclassification is one of the most litigated areas of employment law, with consequences ranging from back taxes to class action lawsuits
• At-will employment exists in most states but comes with dozens of exceptions that vary by jurisdiction

If you're hiring even one person in the U.S., you need to understand how this system works — or partner with a platform that does it for you.

Federal Employment Law: The Foundation You Must Know

Before diving into state-specific rules, let's establish the federal baseline. These are the laws that apply to every employer in every state, regardless of company size (though some have employee-count thresholds).

The Fair Labor Standards Act (FLSA)

The FLSA is the cornerstone of U.S. wage and hour law. It governs:

• Federal minimum wage: Currently $7.25 per hour — though most states have set their own, higher minimums
• Overtime pay: Non-exempt employees must receive 1.5x their regular rate for hours worked over 40 in a workweek
• Child labor restrictions: Rules governing what work minors can do and when
• Exempt vs. non-exempt classifications: This is where many employers get tripped up

The exempt vs. non-exempt distinction is critical. Employees classified as "exempt" don't receive overtime pay. To qualify, they must meet both a salary threshold (currently $684/week as of the 2024 rule, though this has been subject to ongoing legal challenges) and a duties test based on their job function — executive, administrative, professional, outside sales, or computer employee exemptions.

Getting this wrong means potential liability for years of unpaid overtime, plus liquidated damages that can double the amount owed.

Title VII of the Civil Rights Act and Anti-Discrimination Laws

Federal law prohibits employment discrimination based on race, color, religion, sex, and national origin. Over the years, this framework has expanded significantly:

• Age Discrimination in Employment Act (ADEA): Protects workers 40 and older
• Americans with Disabilities Act (ADA): Requires reasonable accommodation for qualified individuals with disabilities
• Pregnancy Discrimination Act: Prohibits discrimination based on pregnancy, childbirth, or related conditions
• Pregnant Workers Fairness Act (PWFA): Enacted in 2023, requires reasonable accommodations for known limitations related to pregnancy
• LGBTQ+ Protections: The Supreme Court's 2020 ruling in Bostock v. Clayton County confirmed that Title VII's prohibition on sex discrimination includes sexual orientation and gender identity

These apply to employers with 15 or more employees (20 for the ADEA), but state laws often extend these protections to smaller employers.

The Family and Medical Leave Act (FMLA)

FMLA entitles eligible employees at covered employers to up to 12 weeks of unpaid, job-protected leave per year for:

• The birth or adoption of a child
• Caring for a spouse, child, or parent with a serious health condition
• The employee's own serious health condition
• Qualifying military exigencies

Coverage applies to employers with 50 or more employees. Employees must have worked for the employer for at least 12 months and logged at least 1,250 hours in the past year.

Here's the catch: many states have their own family leave laws that are more generous — shorter tenure requirements, paid leave, broader family definitions — and those apply regardless of company size.

I-9 Employment Eligibility Verification

Every employer in the United States — without exception — must complete Form I-9 for every employee hired. This verifies that the individual is legally authorized to work in the U.S.

• Employers must examine documents establishing identity and work authorization
• I-9s must be retained for three years after hire date or one year after termination, whichever is later
• E-Verify, the federal electronic verification system, is mandatory for federal contractors and in certain states — but voluntary for most private employers
• Failure to maintain proper I-9 records carries fines from $281 to $2,789 per violation for first-time paperwork violations, and significantly more for knowingly hiring unauthorized workers

The National Labor Relations Act (NLRA)

Even if your workforce isn't unionized, the NLRA applies to most private sector employers. It protects employees' rights to engage in "concerted activity" — discussing wages, working conditions, and organizing. This means:

• You cannot prohibit employees from discussing their salaries
• Blanket social media policies that restrict work-related discussion may be unlawful
• Retaliation against employees for protected concerted activity is a federal violation

Federal Payroll Taxes: What You're Required to Withhold and Pay

Payroll taxation is where compliance gets numerically complex. As an employer in the U.S., you have obligations on two fronts: withholding taxes from employee wages and paying employer-side taxes out of your own pocket.

Social Security and Medicare (FICA)

The Federal Insurance Contributions Act requires both employees and employers to contribute:

• Social Security: 6.2% from the employee + 6.2% from the employer = 12.4% total
  • Applied on wages up to the Social Security wage base ($168,600 in 2024)
• Medicare: 1.45% from the employee + 1.45% from the employer = 2.9% total
  • No wage cap — applies to all earned income
  • Employees earning over $200,000 are subject to an Additional Medicare Tax of 0.9% — but employers only withhold this, they don't match it

Federal Income Tax Withholding

Employers must withhold federal income tax from employees' wages based on:

• The employee's Form W-4 (Employee's Withholding Certificate)
• IRS withholding tables published in Publication 15-T
• Filing status (single, married filing jointly, head of household)
• Additional withholding amounts requested by the employee

The employer doesn't pay this — it's the employee's tax. But you are legally responsible for calculating, withholding, remitting, and reporting it correctly.

Federal Unemployment Tax (FUTA)

Employers pay 6% on the first $7,000 of each employee's wages annually. However, if you pay state unemployment taxes on time, you receive a credit of up to 5.4%, reducing the effective FUTA rate to just 0.6% for most employers.

FUTA is an employer-only tax — you cannot deduct it from employee wages.

Payroll Tax Deposit Schedule

The IRS requires employers to deposit payroll taxes on a schedule based on their lookback period liability:

• Monthly depositors: Deposit by the 15th of the following month
• Semi-weekly depositors: Deposit within 2-3 business days of payroll (based on payday timing)
• Next-day rule: If you accumulate $100,000 or more in tax liability on any single day, you must deposit the next business day

Failure to deposit on time triggers penalties ranging from 2% to 15% of the unpaid amount, depending on how late the deposit is. The Trust Fund Recovery Penalty can personally assess responsible individuals for the employee portion of FICA and income taxes — meaning owners, officers, and even some managers can be held personally liable.

Form 941 and Annual Filing Requirements

• Form 941 (Employer's Quarterly Federal Tax Return): Filed quarterly to report wages paid, taxes withheld, and employer FICA contributions
• Form 940 (Annual FUTA Return): Filed annually for unemployment tax
• Form W-2: Provided to employees and the SSA by January 31 each year, showing annual wages and tax withholdings
• Form W-3: The transmittal form accompanying W-2s to the Social Security Administration

State Employment Laws: Where Compliance Gets Really Complicated

Here's the truth most HR consultants won't tell you upfront: state law is where most compliance violations happen. Federal law provides a consistent baseline, but state laws create a fragmented, ever-changing landscape that trips up even experienced HR professionals.

State Minimum Wage Laws

As of 2024, only a handful of states still use the federal minimum wage of $7.25/hour. Most have enacted higher minimums:

• California: $16/hour statewide (higher in some cities like San Francisco at $18.67/hour)
• Washington: $16.28/hour
• New York: $16/hour in NYC, Long Island, and Westchester; $15/hour elsewhere
• Colorado: $14.42/hour
• Massachusetts: $15/hour
• Florida: $13/hour, on an annual escalator toward $15

And this is just the state level. Cities and counties can set their own minimums above the state level — which means a business with employees in multiple California cities might need to track four or five different minimum wages simultaneously.

State Income Tax Withholding

Nine states have no state income tax: Alaska, Florida, Nevada, New Hampshire (on wages), South Dakota, Tennessee (on wages), Texas, Washington, and Wyoming. Every other state requires employers to:

• Register with the state tax authority
• Obtain a state employer identification number (separate from the federal EIN)
• Withhold state income tax from employee wages
• Remit deposits on state-specific schedules
• File state payroll tax returns on quarterly or annual cycles

Some states — like Pennsylvania — have both state and local income taxes, requiring employers to handle withholding at multiple levels for the same employee.

State Unemployment Insurance (SUI)

Every state runs its own unemployment insurance program. Employers pay state unemployment tax on a portion of each employee's wages, and the rate varies based on:

• New employer rates: Assigned to newly registered employers (typically 2-4%)
• Experience-rated rates: Adjusted annually based on your claims history — more layoffs = higher rate
• Wage base: The amount of each employee's wages subject to SUI tax (varies widely by state, from $7,000 in California to $47,700 in Washington in 2024)

Multi-state employers face a particular challenge: determining which state's SUI applies to an employee who lives in one state and works in another — or works in multiple states. The general rule follows where the work is performed, but reciprocal agreements between states can complicate this further.

Paid Leave Laws: A State-by-State Patchwork

This is one of the most rapidly evolving areas of U.S. employment law. There is no federal paid leave mandate (FMLA is unpaid), so states have stepped in:

Paid Family and Medical Leave (PFML) States:

• California: Up to 60-70% wage replacement for up to 8 weeks of family leave; up to 52 weeks of disability
• New York: Up to 67% of the statewide average weekly wage for up to 12 weeks
• Washington: Up to 90% wage replacement for up to 12 weeks (family) or 18 weeks (own illness)
• Massachusetts: Up to 26 weeks combined family and medical leave
• Oregon: Up to 12-14 weeks at 60% wage replacement
• Colorado, Connecticut, New Jersey, Rhode Island, and others have similar programs

Paid Sick Leave Laws: Over 15 states and dozens of cities mandate paid sick leave. Requirements vary significantly:

• Accrual rate (commonly 1 hour per 30-40 hours worked)
• Cap on annual accrual (typically 40-80 hours)
• Permitted uses (illness, family care, domestic violence, preventive care)
• Carryover and payout requirements

Employers operating in multiple states must track which laws apply to each employee, manage separate accrual buckets, and ensure their PTO policies satisfy the most generous applicable requirements.

State-Specific Wage Payment Laws

Beyond minimum wage and overtime, states impose additional wage payment requirements:

Final paycheck timing:

• California: Immediately upon termination; within 72 hours if the employee quits without notice
• Texas: Within 6 days for discharged employees; by the next regular payday for voluntary resignations
• New York: By next regular payday

Late final paychecks trigger penalties — in California, waiting time penalties accrue at one day's wages for each day the payment is delayed, up to 30 days.

Pay frequency: Many states mandate minimum pay frequencies — weekly, biweekly, or semi-monthly — depending on the industry or employee type.

Wage statement requirements: California, New York, and several other states require detailed pay stubs listing:

• Hours worked
• Applicable pay rates
• Gross and net wages
• All deductions
• Employer name, address, and EIN
• Employee name and last four digits of SSN

Failure to provide compliant pay stubs in California carries penalties of $50 per employee per pay period for first violations and $100 per pay period thereafter, up to $4,000 per employee.

Worker Classification: The $100 Billion Compliance Problem

No topic in U.S. employment law generates more litigation, more back taxes, and more regulatory enforcement than worker misclassification — specifically, treating workers as independent contractors when they should legally be classified as employees.

Why It Matters So Much

Misclassifying employees as contractors means:

• No payroll taxes withheld or remitted
• No employer FICA contributions
• No unemployment insurance paid
• No workers' compensation coverage
• No benefits eligibility
• No wage and hour law protections

When the IRS or state labor agencies discover misclassification, the back liability is staggering: multiple years of unpaid taxes, penalties, interest, and sometimes liquidated damages — all at once.

The IRS Common Law Test

The IRS uses a multi-factor test focusing on behavioral control, financial control, and relationship type:

Behavioral Control:

• Does the company control how the work is done, not just the result?
• Does the company provide training and specify methods?

Financial Control:

• Does the worker have a significant investment in their tools and equipment?
• Can the worker profit or lose money from the engagement?
• Does the worker make services available to the general market?

Type of Relationship:

• Is there a written contract describing an independent contractor relationship?
• Are there employee-type benefits (health insurance, pension, vacation pay)?
• Is the relationship indefinite or for a specific project?
• Is the work central to the company's business?

No single factor is determinative — the IRS weighs the totality of circumstances.

State Tests: Often Stricter Than Federal

Many states apply more worker-friendly tests than the IRS:

The ABC Test (used by California under AB5, and many other states):

A worker is presumed to be an employee unless the hiring entity proves ALL three of the following:

• A: The worker is free from control and direction of the hiring entity in connection with the performance of the work
• B: The worker performs work outside the usual course of the hiring entity's business
• C: The worker is customarily engaged in an independently established trade, occupation, or business

The "B" prong is a game-changer. It means that if a software company hires a software engineer as a contractor, they almost certainly fail prong B — the work IS within the company's core business. California's AB5 has cost hundreds of companies tens of millions in reclassification liabilities.

States using the ABC test (fully or in part): California, New Jersey, Massachusetts, Illinois, Vermont, and others.

The DOL's 2024 Independent Contractor Rule

In January 2024, the Department of Labor issued a new final rule for determining contractor status under the FLSA, replacing the Trump-era 2021 rule. The 2024 rule:

• Returns to a totality-of-circumstances analysis using the "economic reality" test
• Weighs six factors equally (no two are "core" factors)
• Makes it harder to classify workers as contractors
• Increases enforcement risk for gig economy companies and others relying heavily on contractor workforces

This rule has faced legal challenges, but it represents the current regulatory environment employers must navigate.

Hiring Across State Lines: The Remote Work Compliance Explosion

Remote work has fundamentally changed the compliance calculus for U.S. employers. When an employee works from home in a different state than the company's headquarters, that company may:

• Create a tax nexus in the employee's state, triggering corporate income tax obligations
• Be required to register as a foreign employer doing business in that state
• Become subject to that state's employment laws — minimum wage, leave, termination requirements, etc.
• Need to withhold and remit that state's income tax
• Pay that state's unemployment insurance

The explosion of remote work post-pandemic created enormous compliance backlogs. Many companies with 5-10 remote employees spread across 10 different states suddenly realized they had obligations in 10 jurisdictions they'd never operated in before.

The Concept of "Nexus"

Tax nexus is established when a company has sufficient presence in a state to be subject to that state's taxes. One remote employee is generally sufficient to create payroll tax nexus — and often corporate income tax nexus.

States aggressively pursue out-of-state employers who have nexus but haven't registered or remitted taxes. Voluntary disclosure programs exist in most states but require coming clean about prior-year liabilities.

Reciprocity Agreements

Some states have reciprocity agreements that simplify withholding for employees who live in one state and work in another. For example:

• Virginia, Maryland, Washington D.C., West Virginia, Kentucky, and Pennsylvania have various reciprocity arrangements
• An employee who lives in Virginia but works in D.C. may only owe Virginia income tax

But reciprocity agreements are limited and don't exist between most state pairs. Employers must research the specific combination of states relevant to each employee.

Benefits Obligations: What You Must Provide vs. What's Expected

Unlike many countries, the U.S. doesn't mandate most employee benefits at the federal level. But "not mandated" doesn't mean "not expected" — and state mandates are growing rapidly.

Federally Mandated Benefits

• Social Security and Medicare: Through FICA contributions (described above)
• Unemployment insurance: Through FUTA and SUI contributions
• Workers' compensation: Required by state law (not federal), but nearly universal
• COBRA continuation coverage: For employers with 20+ employees, must offer continued health coverage after qualifying events

The Affordable Care Act (ACA) Employer Mandate

Employers with 50 or more full-time equivalent (FTE) employees are "Applicable Large Employers" (ALEs) under the ACA and must:

• Offer minimum essential coverage to full-time employees (those working 30+ hours/week) and their dependents
• Ensure coverage is affordable (employee premium ≤ 9.02% of household income in 2024)
• Ensure coverage provides minimum value (covers at least 60% of costs)
• File Form 1094-C and 1095-C annually

Failure to comply triggers the Employer Shared Responsibility Payment — currently $2,970 per full-time employee (minus the first 30) for not offering coverage at all, or $4,460 per employee who receives a premium tax credit for the affordability/minimum value failure.

State-Mandated Benefits

Several states require employers to provide specific benefits regardless of federal law:

State-mandated health insurance contributions:

• Hawaii requires employers to provide health insurance to employees working 20+ hours/week
• Some cities (San Francisco) require employers to make health spending contributions for covered employees

State disability insurance:

• California, New York, New Jersey, Rhode Island, and Hawaii require short-term disability insurance (typically funded through employee payroll deductions, with some employer contributions)

Retirement plans:

• Several states (California, Illinois, Oregon, Colorado, Connecticut, and others) now require employers without their own retirement plan to enroll employees in a state-run IRA program (e.g., CalSavers, Illinois Secure Choice)

Competitive Benefits: The Market Reality

Even where benefits aren't mandated, competitive hiring in the U.S. market practically requires:

• Health insurance: The most valued benefit; premiums are expensive, and employer contributions typically cover 70-80% for individual coverage
• 401(k) retirement plan: Expected at most mid-size and large employers; employer matching is standard
• Paid time off: Despite no federal mandate, most employers offer 10-20 days annually
• Dental and vision insurance: Near-universal at competitive employers
• Life and disability insurance: Common at larger employers
• Remote work flexibility: Post-pandemic, widely expected in white-collar roles

Onboarding Compliance: The First 30 Days Matter More Than You Think

The onboarding process isn't just about paperwork — it's where many compliance failures originate. Getting it right from day one protects you legally and sets the right tone with new hires.

Required Onboarding Documents

Federal requirements:

• Form I-9: Must be completed within 3 business days of the employee's first day
• Form W-4: Employee withholding certificate (new form required for new hires; existing employees may update at any time)
• FLSA notice: Required in some states (not at the federal level for all employers)

State-specific new hire notices:

Many states require employers to provide written notice at hire of:

• Pay rate and pay frequency
• Employment status (at-will, etc.)
• Applicable leave policies
• Employer name and address
• Workers' compensation carrier information

California's new hire notice requirements (under the Wage Theft Prevention Act) are among the most comprehensive — a written notice required in the employee's primary language containing 17 specific data points.

New Hire Reporting

Federal law requires employers to report all new hires and rehires to their State Directory of New Hires within 20 days of hire. This feeds into the National Directory of New Hires used to enforce child support orders. Failure to report carries penalties.

Background Check Compliance

Background checks are governed by:

• The Fair Credit Reporting Act (FCRA): For checks conducted through third-party agencies, employers must provide a standalone disclosure and authorization, and follow adverse action procedures (pre-adverse action notice, then final adverse action notice)
• Ban the Box laws: Over 35 states and 150+ cities restrict when employers can ask about criminal history — usually requiring a conditional offer first, then an individualized assessment
• EEOC guidance: Recommends against blanket exclusions based on criminal history; requires individualized assessment considering nature of crime, time elapsed, and job relevance

Termination Law: At-Will Employment Has More Exceptions Than You Think

The U.S. is famous for "at-will employment" — the doctrine that either party can end the employment relationship at any time, for any reason or no reason. But this principle has been eroded by so many exceptions that it's often more theoretical than practical.

Federal Protections Against Wrongful Termination

Employees cannot be terminated for:

• Discriminatory reasons: Race, color, religion, sex, national origin, age (40+), disability, pregnancy, genetic information
• Retaliation: Filing a discrimination complaint, participating in an investigation, engaging in protected concerted activity, whistleblowing
• FMLA interference or retaliation: Taking or requesting protected leave
• Exercising FLSA rights: Filing a wage complaint, discussing wages with coworkers
• Jury duty or military service: Protected under federal and state laws

State Wrongful Termination Protections

States have added layers of protection:

• Implied contract exceptions: Employee handbooks with language suggesting job security can create implied contracts in many states
• Implied covenant of good faith and fair dealing: Some states (notably California) recognize this as limiting at-will termination in certain circumstances
• Public policy exceptions: Terminating an employee for refusing to do something illegal, filing a workers' comp claim, or exercising other legal rights is wrongful in most states
• Expanded protected classes: Many states add marital status, sexual orientation, gender identity, source of income, credit history, or political affiliation as protected characteristics

WARN Act Notice Requirements

The federal Worker Adjustment and Retraining Notification (WARN) Act requires covered employers (100+ employees) to provide 60 days advance notice of:

• Plant closings affecting 50+ employees
• Mass layoffs affecting 500+ employees, or 50-499 employees if that's 33% of the workforce

Several states (California, New York, New Jersey, Illinois) have their own "mini-WARN" acts with lower thresholds and longer notice requirements.

The Entity Question: Do You Need a U.S. Legal Entity?

For international companies hiring in the U.S., one of the most consequential early decisions is whether to establish a U.S. legal entity — a corporation or LLC registered to do business in the U.S.

Why a Legal Entity Matters

A U.S. legal entity:

• Enables direct employment (company becomes the legal employer)
• Opens a U.S. bank account under the entity's name
• Allows you to sponsor H-1B and other work visas
• Provides limited liability protection for foreign parent company
• May be required for certain contracts (federal government, enterprise clients)

The Cost and Complexity of Entity Setup

Setting up a U.S. entity is not fast or cheap:

• Incorporation: Relatively straightforward ($500-2,000 in state fees)
• EIN registration: Required from the IRS before hiring
• State registration: "Foreign qualification" required in every state where you have employees or do significant business
• Registered agent: Required in each state where qualified ($100-300/year per state)
• Payroll setup: State registrations, UI accounts, tax withholding accounts in each state
• Compliance infrastructure: Ongoing HR, legal, accounting, and payroll management

For a company with employees in 5 states, you might be managing 10-15 separate government registrations and filing obligations.

The Employer of Record (EOR) Alternative

This is where platforms like Deel fundamentally change the equation.

An Employer of Record (EOR) is a third-party company that legally employs workers on your behalf. Deel becomes the legal employer in the U.S., handling:

• All federal and state payroll tax withholding and remittance
• State employment registrations and filings
• Workers' compensation insurance
• Benefits administration
• Legally compliant employment contracts for each jurisdiction
• New hire reporting and onboarding documentation
• Ongoing compliance monitoring across all applicable laws

You retain full control over the employee's day-to-day work, salary, title, and responsibilities. Deel handles the legal and administrative infrastructure.

This model is especially powerful for:

• International companies testing the U.S. market without committing to entity setup costs
• Companies with remote employees spread across many states (avoiding multi-state registration complexity)
• Fast-growing startups that need to hire quickly without building out HR infrastructure
• Companies in regulated industries where compliance risk is especially high

How Deel Solves U.S. Hiring Compliance End-to-End

Let's be direct: managing U.S. employment compliance in-house is a full-time job — and for multi-state hiring, it often requires a team. The penalties for getting it wrong are severe, and the rules change constantly.

Deel is built specifically to handle this complexity. Here's what makes it the leading choice for businesses hiring in the U.S.:

Locally Compliant Employment Contracts

Deel generates employment agreements that are automatically tailored to the state where your employee will work. A California employee's contract includes required at-will language, California-specific IP assignment provisions, wage statement rights, and other state-mandated disclosures. A New York City employee's contract includes the City's specific anti-discrimination protections and salary transparency compliance.

You don't need to know every state's requirements — Deel's legal infrastructure knows them for you.

Multi-State Payroll Tax Management

Deel handles registration, calculation, withholding, and remittance for:

• Federal income tax, FICA, and FUTA
• State income tax in every state where you have employees
• State unemployment insurance (SUI) in every applicable state
• Local income taxes where applicable (cities like New York City and Philadelphia)
• All quarterly and annual filings (941, 940, W-2s, state equivalents)

This means no missed deposit deadlines, no miscalculated withholding, and no penalties for late filings.

Benefits Administration

Deel offers access to competitive U.S. benefits packages including health, dental, vision, life insurance, and 401(k). Benefits are administered compliantly, and ACA affordability and minimum value requirements are tracked automatically for applicable large employers.

For companies that want to offer strong benefits to attract talent without the administrative burden, Deel's managed benefits solution handles enrollment, carrier management, and ongoing administration.

Worker Classification Support

Deel's platform supports both employee hiring (through EOR) and compliant contractor engagement. For businesses working with both employees and contractors, Deel's Contractor of Record and contractor compliance tools help ensure engagements are structured to minimize misclassification risk — including jurisdiction-specific analysis.

Visa and Immigration Support

For companies that want to sponsor foreign workers in the U.S., Deel connects employers with immigration attorneys for H-1B, O-1, TN, and other visa categories. Managing work authorization alongside payroll and compliance in one platform eliminates coordination gaps that create compliance failures.

Real-Time Compliance Monitoring

Employment law changes constantly — new minimum wages, updated leave requirements, new ordinances, revised overtime rules. Deel's compliance team monitors regulatory changes across all U.S. jurisdictions and updates the platform accordingly. You don't need a legislative tracking subscription — Deel builds that into the service.

The Cost Math

Consider what in-house multi-state U.S. compliance actually costs:

• HR/payroll manager or outsourced payroll service
• Employment attorney for contract review and compliance questions
• State registrations and registered agents in multiple states
• Workers' compensation insurance management
• Benefits administration overhead
• The risk of penalties and litigation if anything is missed

For many companies — especially those hiring in 3+ states — Deel's EOR model is less expensive than the fragmented in-house approach, even before accounting for risk mitigation.

Special Situations: Hiring in High-Complexity States

Some states deserve special attention because their employment laws are significantly more complex and more aggressively enforced than the national average.

California: The Gold Standard of Employee Protections

California is functionally a different employment law universe. Key considerations:

• AB5 and independent contractor classification: The ABC test makes true independent contractor relationships very narrow
• Meal and rest break requirements: Non-exempt employees must receive an unpaid 30-minute meal break before the end of the 5th hour of work and a paid 10-minute rest break every 4 hours — failure triggers premium pay (one additional hour at the regular rate per missed break)
• Wage statement requirements: One of the most detailed in the country; errors trigger per-employee, per-period penalties
• Final pay requirements: Immediate payment upon termination or discharge
• PAGA (Private Attorneys General Act): Allows employees to sue on behalf of the state for labor code violations, with 75% of penalties going to the state and 25% to the aggrieved employees — this law drives enormous amounts of litigation
• Salary history ban: Employers cannot ask about or consider candidates' prior salary history
• Pay scale transparency: Must provide pay scale to applicants upon request and include pay ranges in job postings

New York: Dense Urban Markets and Layered Local Laws

• New York City Human Rights Law: Broader protections than state or federal law, covering employers with 4+ employees
• NYC salary transparency: Job postings must include good-faith minimum and maximum salary ranges
• Paid safe leave: Employees can use sick leave for situations involving domestic violence
• Retail scheduling law: NYC fast food and retail employers face advance scheduling requirements and "clopening" restrictions
• State paid family leave: One of the most generous programs in the country, with regular benefit increases

Illinois: Chicago Adds Another Layer

• Chicago minimum wage: Higher than Illinois state minimum
• Chicago Paid Leave and Paid Sick and Safe Leave Ordinance: Up to 40 hours of paid leave (for any reason) plus up to 40 hours of paid sick and safe leave annually
• Illinois BIPA: Biometric privacy law with major implications for employers using time-tracking systems that capture fingerprints or facial recognition
• Illinois Human Rights Act: Covers employers with one or more employees (compared to federal Title VII's 15-employee threshold)

Key Compliance Checklist for U.S. Hiring

Whether you're building your compliance infrastructure from scratch or auditing existing processes, this checklist covers the critical bases:

Before You Hire:

• Obtain federal Employer Identification Number (EIN)
• Register with state tax authorities in each state where you'll employ workers
• Set up state unemployment insurance accounts
• Obtain workers' compensation insurance (required in virtually all states)
• Prepare legally compliant offer letters and employment agreements
• Establish a written employee handbook with state-required policies

At Onboarding:

• Complete Form I-9 within 3 business days
• Collect signed Form W-4 (and state equivalent if applicable)
• Provide all required state new hire notices
• Report new hire to state new hire directory within 20 days
• Enroll in benefits within applicable enrollment windows

Ongoing Payroll Compliance:

• Withhold and remit all federal, state, and local payroll taxes on schedule
• File Form 941 quarterly
• Provide compliant pay stubs on each payday
• Monitor minimum wage changes (annual or periodic in most states)
• Track leave accruals and balances under applicable state laws
• Provide ACA-required notices and maintain coverage for ALEs

At Termination:

• Issue final paycheck within state-required timeframe
• Provide COBRA or state continuation coverage notice within required period
• Properly document the reason for termination
• Comply with WARN Act or state mini-WARN requirements for mass layoffs

The Bottom Line: Don't Navigate U.S. Hiring Compliance Alone

The U.S. hiring landscape is genuinely one of the most complex in the world — not because of any single law, but because of the compounding effect of federal, state, and local requirements that interact differently in every jurisdiction. Miss a California meal break requirement, misclassify a contractor in Massachusetts, or fail to provide a New York City salary range on a job posting, and you're looking at real financial exposure.

The companies that get this right are the ones that build or buy the infrastructure to manage it — not the ones that hope they're in compliance or rely on outdated templates from a quick Google search.

If you're hiring across U.S. states — whether you're a domestic company managing remote workers or an international company entering the U.S. market — the most important decision you'll make isn't which state to incorporate in or which payroll software to buy. It's whether you have the right compliance partner to manage this complexity as it evolves.
