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 |
| Wells Fargo Initiate Business Checking | $10 | Maintain $500 daily balance | 100 free transactions | Wide branch network, basic business needs |
| 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.
Option 1: Online Banks (Recommended)
Mercury, Relay, and other neobanks accept non-US residents and can open accounts remotely. The process typically requires:
- A US-registered business entity (LLC or Corp)
- An EIN
- Valid passport
- Proof of foreign address
- 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
- Keep personal and business finances completely separate: Never use your business account for personal expenses or vice versa
- Maintain adequate records: Download and save monthly statements; categorize transactions
- Reconcile monthly: Match bank statements to your accounting records every month
- Set up proper access controls: Use multi-user access with appropriate permission levels
- Monitor for fraud: Enable transaction alerts and review account activity regularly
- 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.
