Opening a US Business Bank Account: Requirements for Foreign and Domestic Businesses

Complete guide to opening a US business bank account in 2026. Required documents, best banks for businesses, non-resident options, Mercury, Wise, Relay, Brex, EIN and ITIN requirements.

A dedicated business bank account is one of the first operational necessities for any US company. Beyond basic financial management, a business bank account is essential for maintaining the legal separation between personal and business finances that protects the limited liability of your LLC or corporation. Commingling personal and business funds is one of the most common reasons courts "pierce the corporate veil," leaving business owners personally liable for company debts and obligations.

The US banking landscape for businesses ranges from traditional banks with thousands of physical branches to fully digital neobanks designed specifically for startups and online businesses. For domestic entrepreneurs, opening a business bank account is relatively straightforward. For foreign nationals operating US companies from abroad, the process is more complex but has been dramatically simplified by online banking platforms that cater specifically to international entrepreneurs.

This guide covers everything you need to know about opening and managing a US business bank account in 2026: required documents, the best banks for different business types, options for non-resident business owners, fee comparisons, and practical recommendations.

Required Documents

The exact requirements vary by bank, but most require the following:

For LLCs

Document Required? Notes
EIN (Employer Identification Number) Yes Obtain free from IRS
Articles of Organization Yes Filed with your state of formation
Operating Agreement Usually Some banks require it; always recommended
Government-issued photo ID Yes For all signers/members
Proof of business address Sometimes Utility bill, lease, or registered agent letter
Business license Sometimes If required in your jurisdiction

For Corporations

Document Required? Notes
EIN Yes Obtain free from IRS
Articles of Incorporation Yes Filed with your state of formation
Corporate bylaws Usually Document governing corporate operations
Board resolution authorizing account opening Sometimes Required by some banks
Government-issued photo ID Yes For all authorized signers
Certificate of Good Standing Sometimes Recent certificate from secretary of state

Additional Documents for Non-Residents

Document Required? Notes
Passport Yes Current, valid passport
ITIN (Individual Taxpayer Identification Number) Sometimes Required by some traditional banks
Proof of foreign address Usually Utility bill or bank statement
US business address Usually Registered agent address may suffice
Visa (if present in the US) Sometimes Traditional banks may request

One of the most common frustrations for new business owners is arriving at a bank only to discover they are missing a required document. Before visiting a branch or beginning an online application, call the bank or check their website for the specific requirements. Requirements can vary not only between banks but between branches of the same bank. Having all documents ready -- including the EIN confirmation letter (CP 575), original or certified copies of formation documents, and all identification -- will save time and prevent the need for multiple visits.

Best Banks for US Businesses

Traditional Banks

Traditional banks offer the advantage of physical branches, ATM networks, and a full range of business services including loans, lines of credit, and merchant services.

Bank Monthly Fee Fee Waiver Free Transactions Key Features
Chase Business Complete $15 Maintain $2,000 balance or use Chase card 20 free transactions Largest branch/ATM network, QuickBooks integration
Bank of America Business Advantage $16 Maintain $5,000 balance 200 free transactions Preferred Rewards program, extensive online tools

US Bank Silver Business Checking $0 No fee 150 free transactions Free account with good feature set
PNC Business Checking $7 Maintain $500 balance 150 free transactions Strong business lending, regional presence

Online / Neobanks

Digital banks have emerged as strong alternatives for businesses that do not need physical branches. They typically offer lower fees, better digital tools, and faster account opening.

Bank Monthly Fee Key Features Best For
Mercury $0 API access, FDIC insured, team permissions, integrations, up to $5M FDIC via partner banks Startups, tech companies, non-residents
Relay $0 Up to 20 checking accounts, profit-first budgeting, auto-transfers Small businesses, freelancers
Brex $0 (basic) Corporate cards with no personal guarantee, spend management, bill pay Startups, funded companies
Novo $0 Invoicing, integrations, reserves feature Freelancers, small businesses
Bluevine $0 2.0% APY on balances up to $250K, checks, bill pay Businesses wanting to earn interest

Mercury has become the dominant choice for startup and tech company banking due to its combination of zero fees, excellent API and integration capabilities, and willingness to serve non-US residents. Mercury offers virtual and physical debit cards, domestic and international wire transfers, and integrates with major accounting software. For non-resident business owners who cannot visit a US bank branch, Mercury's fully remote account opening process is a significant advantage. However, Mercury is not a bank itself -- it partners with Choice Financial Group and Column N.A. for banking services.

Opening an Account as a Non-US Resident

Foreign entrepreneurs face additional challenges when opening US business bank accounts, but several viable pathways exist.

Mercury, Relay, and other neobanks accept non-US residents and can open accounts remotely. The process typically requires:

  1. A US-registered business entity (LLC or Corp)
  2. An EIN
  3. Valid passport
  4. Proof of foreign address
  5. Company formation documents

Processing typically takes 1 to 5 business days. No US visit is required.

Option 2: Traditional Banks (In-Person)

If you prefer a traditional bank and can visit the US, major banks like Chase, Bank of America, and Wells Fargo will open business accounts for non-resident company owners. Requirements are stricter:

  • Must visit a branch in person
  • May require ITIN or SSN (requirements vary by branch)
  • May require a minimum opening deposit ($100 to $1,000+)
  • May require a US address beyond just a registered agent

Option 3: International Banking Solutions

Service Type Features Fees
Wise Business Multi-currency account USD account details, 40+ currencies, cheap international transfers Low percentage-based fees
Payoneer Payment platform USD receiving account, multi-currency, marketplace integration Varies by service
Airwallex Business account USD and multi-currency accounts, international payments, card issuance Low fees, some free features

These are not traditional bank accounts but provide US account numbers (routing and account numbers) that can receive payments. They are useful for businesses that primarily receive payments from US clients but are managed internationally.

Business Banking Fees Comparison

Common Fee Categories

Fee Type Traditional Banks Online Banks
Monthly maintenance $0-$30 $0 (typically)
Domestic wire (outgoing) $15-$30 $0-$5
International wire (outgoing) $35-$50 $5-$16
ACH transfer $0-$3 $0
Cash deposit First $5-10K free, then fee Often not available
Debit card replacement $5-$10 $0
Paper checks $15-$50 per box Often not offered
Overdraft fee $30-$35 Varies (some have none)

Total Annual Cost Comparison (Typical Small Business)

Scenario Chase Business Complete Mercury Relay
Monthly fee $180/year (or $0 with $2K balance) $0 $0
5 domestic wires/month $900-$1,800/year $0 $0
2 international wires/month $840-$1,200/year $120-$384/year $120-$384/year
Estimated annual cost $1,920-$3,180 $120-$384 $120-$384

The fee difference between traditional and online banks is substantial for businesses that make frequent wire transfers. A startup making 5 domestic wires and 2 international wires per month could save $1,500 to $2,800 per year by using Mercury or Relay instead of a traditional bank. The main trade-off is the lack of physical branches (important for cash-intensive businesses) and the absence of traditional business lending relationships. Many businesses maintain both: a traditional bank account for local banking and cash deposits, and an online account for day-to-day operations and payments.

Maintaining Your Business Bank Account

Best Practices

  1. Keep personal and business finances completely separate: Never use your business account for personal expenses or vice versa
  2. Maintain adequate records: Download and save monthly statements; categorize transactions
  3. Reconcile monthly: Match bank statements to your accounting records every month
  4. Set up proper access controls: Use multi-user access with appropriate permission levels
  5. Monitor for fraud: Enable transaction alerts and review account activity regularly
  6. Maintain minimum balances: Avoid fees and maintain a cash cushion for unexpected expenses

Account Closure and Migration

If you need to change banks, plan the transition carefully:

  • Open the new account before closing the old one
  • Update all automatic payments and deposits to the new account
  • Maintain both accounts for at least 1 to 2 months during transition
  • Request final statements from the closed account for your records
  • Update your EIN records if the bank account is referenced in any IRS filings

Business Banking and Credit

Your business bank account history is a foundation for building business credit. Maintaining healthy balances, consistent deposits, and responsible use of any credit products (business credit cards, lines of credit) linked to your bank account contributes to your overall creditworthiness. See our business credit building guide for detailed strategies.

Frequently Asked Questions

What documents do I need to open a US business bank account?

Required documents typically include: EIN (Employer Identification Number) from the IRS, articles of organization or incorporation, operating agreement or bylaws, government-issued photo ID for all signers, proof of business address, and in some cases a business license. Some banks require additional documentation for non-US owners, such as a passport, visa, and proof of foreign address. Requirements vary by bank.

Can a non-US resident open a business bank account in the USA?

Yes, but options are more limited. Traditional banks like Chase, Bank of America, and Wells Fargo typically require in-person visits and may require a US visa or Social Security Number. Online banking options like Mercury, Relay, and Brex specifically cater to non-resident business owners and can be opened remotely. You will need at minimum an EIN and your company formation documents. An ITIN (Individual Taxpayer Identification Number) may also be required.

Which banks are best for small businesses in the USA?

For traditional banking: Chase Business Complete is the most widely available with extensive branch and ATM networks. For online-first banking: Mercury offers free business banking with excellent digital tools and API access. Relay provides free business banking with multiple accounts and profit-first budgeting features. Brex is designed for startups and offers corporate cards without personal guarantees. The best choice depends on whether you need physical branches, international features, or startup-specific tools.

Is an EIN required to open a business bank account?

For multi-member LLCs and all corporations, an EIN is required. Single-member LLCs can technically use the owner's Social Security Number, but most banks strongly prefer or require an EIN regardless. Obtaining an EIN is free and can be done instantly online at irs.gov if you have a US Social Security Number or ITIN. Foreign applicants without SSN/ITIN must apply by fax or mail, which takes 4 to 6 weeks.
