The True Cost of US Expansion for International Businesses
Expanding into the United States is a major growth step, and it costs more than most first budgets assume. The headline costs are easy to spot. The hidden ones, from state compliance to benefits and banking, are what catch international companies out.
This guide sets out the main costs of US expansion for international businesses, with a focus on remote teams rather than physical offices. Use it to build a realistic first-year budget before you commit.
Understanding the American market
The US is a large and valuable market. Its population was about 341.8 million in 2025, according to the US Census Bureau. Foreign direct investment in the US reached $5.86 trillion at the end of 2025, according to the Bureau of Economic Analysis.
Scale brings complexity. The US has federal rules, 50 sets of state rules and many local ones. Each layer adds costs that do not exist, or look very different, in your home market.
Hidden costs to consider when expanding to the US
1. Legal and regulatory compliance
Federal agencies regulate areas such as employment, workplace safety and specific industries. Each state then adds its own rules on employment, data privacy, licensing and tax. Cities and counties can add business licences and local taxes.
Typical legal costs include:
- Business registration and state licensing fees
- Drafting and reviewing contracts for US law
- Trademark and patent filings
- Annual reports, registered agent fees and compliance checks
- Advice on industry-specific regulations
Tip: budget for ongoing legal and compliance support, not just setup. Employment rules change often, especially at state level.
2. Taxes and accounting
The federal corporate income tax rate is 21%. Most states add their own corporate income tax, while a few have none. Many states also charge sales tax, and you can owe tax in a state because of your sales there, even without a physical presence.
Cross-border businesses also need advice on how their home company and US entity interact. That makes US tax and accounting support a significant annual cost. Foothold does not give tax advice, so work with a qualified US tax adviser from the start.
Tip: check where your sales and employees create tax obligations before you hire or sell in a new state.
3. Employment costs
Employment is usually the largest cost of US expansion. Salary is only part of it. In the private sector, benefits made up 30% of employers’ compensation costs in June 2026, according to the Bureau of Labor Statistics.
- Payroll taxes: employers pay 6.2% Social Security tax on wages up to $184,500 in 2026, according to the Social Security Administration, plus 1.45% Medicare tax on all wages. Federal and state unemployment taxes come on top.
- Health insurance: there is no NHS equivalent, so employers usually provide cover. In KFF’s 2025 Employer Health Benefits Survey, employers paid an average of $7,885 a year towards single cover and $20,143 towards family cover.
- Workers’ compensation insurance: required in almost every state, with rates that vary by state and job type.
- Paid time off: there is no federal requirement for paid holiday, but US employers usually offer it to compete for talent. Some states and cities require paid sick leave.
- Retirement plans: many employers offer a 401(k) plan with a company match.
- Outsourced HR and compliance: an Employer of Record typically costs about $9,000 to $12,000 per employee per year, charged as a flat monthly fee. See our guide to Employer of Record costs. If you have your own entity, our PEO+ Cross-Border Support covers payroll, benefits and HR compliance.
Tip: budget salary plus benefits and taxes, not salary alone. An Employer of Record makes these costs predictable while you test the market.
4. Remote work infrastructure
A remote US team needs secure laptops, collaboration tools, cybersecurity and IT support that covers US hours. Many companies also contribute to home office equipment. Data protection matters too, especially when US staff handle data about UK or EU individuals.
Tip: agree remote work policies, equipment and IT support before your first hire starts.
5. Marketing and localisation
US buyers expect US spelling, dollar pricing, US case studies and messaging that suits their market. Many companies need a localised website, new sales materials and a budget for events, paid media and partners. Regional differences in buyer behaviour can also mean different campaigns for different parts of the country.
Tip: test your messaging with US buyers early and adjust it based on results.
6. Banking and financial services
Opening a US business bank account can take time for international founders, and some banks still ask for an in-person visit. Expect monthly account fees, international transfer and currency costs, and payment processing fees. Building a US credit history also takes time.
Tip: start banking early, compare banks and fintech providers, and plan for currency swings in your budget.
Industry-specific insights
Life sciences
Regulatory approval, clinical work and specialist advisers are the main extra costs. FDA requirements shape timelines and budgets, and intellectual property protection is essential. Many companies partner with US research institutions or contract research organisations to share the load.
Technology
Talent is the main cost driver, especially in established tech hubs. Data privacy laws, such as California’s, and US intellectual property protection add legal costs. Many tech companies hire in lower-cost hubs to balance salaries and access to talent.
Recruitment and staffing
US labour and anti-discrimination laws apply to how you recruit as well as who you employ. Multi-state operations need advice on each state’s rules. Employer branding for the US market is a further cost to plan for.
Online education
Accreditation, student data privacy rules and a crowded market add cost and time. Content often needs adapting for US learners and institutions.
Professional services
Many professions need state licences, and professional liability insurance is essential in the US. Building a reputation takes time and investment in networking, events and partnerships.
Navigating the complexities of US expansion
The costs of US expansion span six main areas:
- Legal and regulatory compliance: federal, state and local rules need ongoing attention.
- Taxes and accounting: the multi-layered US tax system needs expert advice.
- Employment: payroll taxes and benefits add significantly to salary.
- Remote work infrastructure: secure, supported systems for a distributed team.
- Marketing and localisation: messaging and materials built for US buyers.
- Banking and financial services: account setup, transfers and currency costs.
Industry-specific requirements add further costs in sectors such as life sciences, technology, recruitment, online education and professional services.

Frequently Asked Questions
Get answers to all your questions and take the first step towards a US business expansion.
What are the typical costs of expanding a business into the US market?
The main costs are entity setup and compliance, US taxes, employment, IT, marketing and banking. Employment is usually the largest. On top of salary, you pay payroll taxes, health insurance and other benefits. An Employer of Record replaces much of the setup cost with a flat monthly fee per employee, which makes early costs easier to predict.
How can a company estimate the budget required for a successful expansion into the US?
Start with your entry route, then list every cost by category: setup, compliance, salaries and benefits, IT, marketing, travel and advisers. Add industry costs such as licences or certification. Then add a contingency, because hiring and sales often take longer than planned. Our team can review your budget against what similar companies have spent.
What role does market research play in determining the cost of expanding into the US?
Market research shows where your customers are, what they will pay and who you compete with. That shapes your costs, from which city you hire in to how much you spend on marketing and localisation. Good research also cuts the risk of surprise costs, such as reworking your pricing or product after launch.
Are there any government incentives or grants available to offset the costs of US expansion?
Yes. States and cities offer incentives such as tax credits, training grants and economic development programmes, usually tied to job creation or investment. SelectUSA, the federal investment programme, can point you to state contacts. Eligibility and value vary widely, so check the terms before you build any incentive into your budget.
