The Globalli team, Globalli13 Nov 2025

The United States represents 28.4% of the global PEO and EOR market, yet international businesses expanding into American territory face a complex web of federal, state, and local compliance requirements that can derail even the most promising market entry strategies. With cross-border hiring accelerating and evolving tax legislation reshaping international business incentives, companies need sophisticated Employer of Record solutions to navigate the complexities of U.S. employment, payroll, and taxation without the delays of entity establishment.

This article outlines actionable strategies for expanding your business into the United States, covering entity setup decisions, hiring practices, payroll compliance, tax obligations, and ongoing workforce management to ensure legal compliance and operational success in the world's largest economy.

How to Plan Your Global Expansion Strategy for the United States

Step 1: Choose Your Market Entry Structure

International companies entering the U.S. market face a strategic decision between establishing local legal entities or leveraging alternative employment structures. Traditional entity establishment involves 6-12 month timelines, state-specific registration fees ranging from $500-$5,000, ongoing annual compliance costs ($10,000-$50,000), legal counsel fees ($5,000-$25,000), and physical address requirements.

The EOR alternative provides immediate hiring capability without entity establishment. The EOR serves as the legal employer, handling federal and state compliance obligations, while your company maintains operational control over day-to-day work activities.

Use EOR when:

You need immediate market entry without multi-month setup delays
Initial team size will be under 50 employees
You require flexibility to scale based on market response
You want to test the U.S. market before committing to permanent infrastructure
You lack local compliance expertise

Establish a local entity when:

Long-term operations with 100+ employees are planned
Manufacturing facilities or physical infrastructure are required
Government contracts demand local incorporation
Your market commitment exceeds 5-10 years with substantial revenue projections

Globalli enables seamless flexible employment transitions, allowing companies to shift workers from contractor status to EOR arrangements to direct employment as business needs evolve, all within the same platform.

Step 2: Understand Worker Classification Requirements

The IRS applies rigorous tests to determine worker classification, with misclassification penalties including retroactive tax payments, benefit obligations, and potential legal action. The IRS evaluates worker relationships across these dimensions:

Behavioral Control: Instructions about when, where, and how work is performed; training provided; degree of supervision; requirements to follow company processes
Financial Control: Investment in equipment by worker; unreimbursed business expenses; opportunity for profit or loss; services available to relevant market
Relationship Type: Written contracts; employee-type benefits; permanency expectations; services as key aspect of regular business
State-specific classification rules: Many states impose stricter standards than federal guidelines. California's ABC test presumes employment status unless the company proves the worker is free from control, performs work outside the usual business course, and is engaged in an independently established trade.

Consider transitioning contractors to employees when work duration extends beyond 6-12 months continuously, the company exercises significant control, the worker provides services exclusively for your organization, or the role involves core business functions.

Globalli Agent of Record services assume legal liability for contractor relationships with AI-powered misclassification risk assessments, protecting against IRS penalties while enabling workforce flexibility.

Step 3: Navigate Federal Tax Obligations

U.S. employers face comprehensive federal tax obligations administered by the IRS. Foreign companies must obtain an Employer Identification Number (EIN) before hiring U.S. workers—immediate for online applications, 4-5 weeks for international mail applications.

Federal Employment Tax Components:

Social Security Tax:

6.2% employer contribution on wages up to $176,100 annual cap (2025)
6.2% employee withholding (total 12.4% combined)

Medicare Tax:

1.45% employer contribution on all wages (no cap)
1.45% employee withholding (total 2.9% combined)
Additional 0.9% Medicare tax on employee wages exceeding $200,000 (employee-only)

Federal Unemployment Tax (FUTA):

6.0% on first $7,000 of each employee's annual wages
Reduced to 0.6% effective rate with state unemployment tax credit

Federal Income Tax Withholding:

The U.S. employs progressive federal income tax with seven brackets for 2025:

Single Filers:

10% on income up to $11,925
12% on income $11,926 to $48,475
22% on income $48,476 to $103,350
24% on income $103,351 to $197,300
32% on income $197,301 to $250,525
35% on income $250,526 to $626,350
37% on income over $626,350

Married Filing Jointly:

10% on income up to $23,850
12% on income $23,851 to $96,950
22% on income $96,951 to $206,700
24% on income $206,701 to $394,600
32% on income $394,601 to $501,050
35% on income $501,051 to $751,600
37% on income over $751,600

Employee Form W-4 elections determine withholding through filing status selection, multiple jobs adjustment, dependent credits, other income reporting, and additional withholding amounts.

Globalli’s Global Payroll automates tax withholding calculations with real-time rate updates, ensuring compliance with federal IRS obligations through AI-powered gross-to-net calculations.

Step 4: Manage State and Local Tax Complexity

Beyond federal obligations, U.S. employers must navigate complex state and local taxation systems varying dramatically across 50 states and thousands of municipalities.

State Income Tax Variations:

Zero Wage Income Tax States (9 total): Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (NH historically taxed interest/dividends but repealed this for wage income).

Progressive Tax States:

California: 1% to 13.3% (highest marginal rate nationally)
New York: 4% to 10.9%
Hawaii: 1.4% to 11%

Flat Tax States:

Illinois: 4.95%
Pennsylvania: 3.07%
Michigan: 4.25%

Remote Work Tax Implications:

The shift to remote work creates complex nexus scenarios. New York's "convenience of employer" rule taxes nonresidents working remotely for NY-based employers if work is performed for "convenience" rather than employer necessity. Some states maintain reciprocal agreements allowing employees to pay income tax only to their state of residence. Employers must withhold for the state where work is physically performed in most circumstances.

State Unemployment Insurance (SUI):

Each state administers independent unemployment insurance programs with tax rates from 0.1% to 14% depending on state and employer experience rating, and wage bases varying significantly by state.

State Disability Insurance (SDI):

Five states require disability insurance:

California: 1.1% on all wages (no cap as of 2024)
Hawaii: Varies by plan; employer may require employee contributions up to 0.5%
New Jersey: 0.14% on wages up to $161,400
New York: 0.5% capped at $0.60 per week
Rhode Island: 1.1% on wages up to $84,000

Globalli’s country-specific configuration workflows ensure adherence to state and local U.S. regulations with automated compliance monitoring across all jurisdictions.

Step 5: Establish Compliant Payroll Infrastructure

Setting up U.S. payroll requires systematic registration and robust processing infrastructure.

Essential Registration Requirements:

Federal: EIN from IRS, EFTPS enrollment, E-Verify authorization (if required)
State: Tax identification number(s), unemployment insurance account, workers' compensation insurance, new hire reporting
Local: Municipal tax registration (applicable in ~5,000 jurisdictions), occupational privilege taxes

Payroll Frequency Requirements:

Most states require payment at least biweekly (every 16 days). Some states allow monthly payment for exempt employees only. Manual laborers often require weekly payment in several states.

Direct Deposit Infrastructure:

Federal law (Regulation E) prohibits requiring employees to use a specific bank; employers may require electronic payment if employees can choose the financial institution, subject to stricter state laws. Infrastructure requires NACHA authorization, banking relationship with ACH capability, employee authorization forms, prenote verification, and backup payment methods.

Globalli’s Global Payroll supports monthly, semi-monthly, and bi-weekly pay cycles with flexible pay date selection while maintaining compliance with state-specific requirements through virtual banking infrastructure in 20 currencies.

Step 6: Implement Employee Benefits and Compliance Mandates

Affordable Care Act (ACA) Employer Mandate:

Organizations with 50+ full-time equivalent employees must offer minimum essential coverage to 95% of full-time employees. Coverage must be affordable (employee premium ≤ 8.39% of household income for 2025) and provide minimum value (60% actuarial value).

ACA Reporting Requirements:

Form 1095-C to each full-time employee by March 2
Forms 1094-C and 1095-C to IRS by February 28 (paper) or March 31 (electronic)
Penalties: $3,060 per full-time employee (minus first 30) for failure to offer coverage
Affordability penalties: $4,590 per affected employee receiving marketplace subsidy

Family and Medical Leave Act (FMLA):

Employers with 50+ employees within a 75-mile radius must provide 12 weeks unpaid leave for birth/adoption, serious health conditions, or military family reasons, with job protection and benefits continuation.

State-Mandated Benefits:

Many states require paid family and medical leave, short-term disability, and paid sick leave beyond federal requirements. Eighteen states and numerous municipalities mandate paid sick leave with a typical accrual of 1 hour per 30-40 hours worked.

Globalli’s Benefits Administration delivers automated enrollment workflows with compliance tracking for ACA, ERISA, and HIPAA, plus country-specific benefits configuration.

Step 7: Complete Hiring Documentation and Year-End Reporting

Form I-9 Employment Eligibility Verification:

All U.S. employers must complete Form I-9 for every hire. Section 1 must be completed on or before the first day of work; Section 2 within 3 business days with physical examination of original documents. COVID-era flexibilities ended July 31, 2023 (with remediation through August 30, 2023). Penalties for non-compliance range from $272 to $2,701 per form for paperwork violations, up to $27,018 per violation for knowingly hiring unauthorized workers.

E-Verify Requirements:

E-Verify is mandatory for federal contractors and subcontractors and in several states with varying requirements by employer type and size. Voluntary for other employers. Alternative procedures exist for E-Verify participants conducting remote document examination.

Contractor Payments and 1099 Reporting:

Businesses must file Form 1099-NEC for independent contractors paid $600+ annually for services. The filing deadline is January 31 to both recipient and IRS. Late filing penalties range from $60 to $310 per form depending on delay.

Year-End Tax Reporting:

January 31 deadline:

Furnish Form W-2 to employees
Furnish Form 1099-NEC to contractors
File Form 1099-NEC with IRS
Submit Form W-2 to Social Security Administration (paper or electronic)
File Form 940 (FUTA) OR extension to February 10 if deposits made timely

March 31 deadline (electronic filing):

File Form 1099-MISC electronically with IRS
File ACA Forms 1094-C and 1095-C with IRS

Frequently Asked Questions

Can foreign companies hire U.S. employees without establishing a legal entity?

Yes, through Employer of Record (EOR) arrangements. EOR providers act as the legal employer, handling all compliance, payroll, benefits, and tax obligations while the foreign company maintains day-to-day management of workers. This enables hiring within weeks versus 6-12 months for entity establishment, making it ideal for testing U.S. markets or expanding rapidly without infrastructure delays. Companies planning significant long-term operations (100+ employees, multiple locations) may eventually find direct entity establishment more cost-effective.

What are the penalties for misclassifying employees as independent contractors?

Misclassification penalties can be severe. Federal consequences include retroactive payment of employer Social Security and Medicare taxes (7.65% of wages), unemployment taxes, federal income tax withholding shortfalls, and retroactive employee benefits. The IRS may assess penalties up to $50 per Form W-2 not filed plus 1.5% of wages for failure to withhold income tax and 40% of FICA taxes not withheld. The Department of Labor may assess penalties up to $2,074 per violation for FLSA violations. Some states impose fines of $5,000-$25,000 per misclassified worker plus criminal penalties for willful violations.

Do all U.S. states have the same payroll tax requirements?

No, requirements vary dramatically. Nine states impose no wage income tax, while California's top rate reaches 13.3%. State unemployment insurance tax rates range from 0.1% to 14% on varying wage bases. Some states mandate paid family leave, short-term disability, and paid sick leave while others impose no such requirements. Minimum wage varies from $7.25 federal minimum to over $16.50 in several jurisdictions. Overtime rules differ, with California requiring daily overtime while most states follow only weekly standards. This complexity makes automated compliance platforms essential for multi-state operations.

How do companies handle payroll when employees work remotely across multiple states?

Multi-state remote work creates complex withholding obligations. Generally, employers must withhold income tax for the state where work is physically performed. This requires tracking employee work locations, registering for withholding accounts in each applicable state, applying state-specific calculations, and filing quarterly returns in each jurisdiction. Some states impose "convenience of employer" rules (notably New York) taxing nonresidents working remotely for in-state employers. Companies must also establish nexus determinations for state unemployment insurance and consider local municipality taxes in approximately 5,000 jurisdictions nationwide.

What are the essential first steps for hiring your first U.S. employee?

Begin 3-6 months before intended hire: (1) Determine expansion model—EOR for speed versus entity establishment for long-term commitment, (2) Obtain Employer Identification Number from IRS, (3) Decide employment structure—employees versus contractors based on IRS classification tests, (4) Research state-specific requirements for target locations including registration and labor law obligations, (5) Select payroll processing solution with U.S. multi-jurisdictional capabilities, (6) Develop compliant employment contracts addressing at-will employment, benefits, and intellectual property, (7) Establish I-9 verification procedures and E-Verify enrollment if required, (8) Set up payment infrastructure. Companies seeking to hire within weeks typically find EOR arrangements most practical for initial market entry.
