You can open most business checking accounts entirely online in 15 to 30 minutes
The process starts with choosing a bank or credit union, then moving through their online application. You'll enter your business information, personal details, and tax identification number. Most banks fund the account the same day or within one business day, though some require a small deposit first. You won't need to visit a branch unless the bank asks you to verify documents in person, which is rare.
The speed depends on the bank. Online-first banks like Mercury, Brex, and Novo often complete the process in under an hour. Traditional banks like Chase, Bank of America, and Wells Fargo typically take one to three business days because they run additional verification checks. Credit unions vary widely—some finish the same day, others take up to a week.
Key Takeaways
- You will need your Social Security number or Individual Tax Identification Number, your business structure (sole proprietorship, LLC, S-corp, etc.), and either an EIN or your business registration documents.
- Most banks ask for your personal address, business address, and expected monthly transaction volume during the online application.
- The account is usually ready to use the same day or next business day, though some banks hold deposits for 24 to 48 hours before releasing funds.
- Online-first banks move faster but may have higher fees or stricter limits on cash deposits; traditional banks are slower but offer more branch access and services.
What documents and information to gather before you start
Have these items ready before you begin the application. You'll need your Social Security number or ITIN, your business's Employer Identification Number (EIN) if you have one, or your state business registration number if you don't. If your business is an LLC, corporation, or partnership, have your formation documents or a copy of your Articles of Organization.
You'll also need a personal address (yours, not just the business address), your business address, and your phone number. Some banks ask for your expected monthly deposit and withdrawal amounts. If your business is brand new and you don't have an EIN yet, most banks will let you use your Social Security number temporarily, though you'll need to provide the EIN within 90 days.
Have a government-issued ID ready—a driver's license or passport. A few banks ask for a photo during the application, so make sure the lighting is clear. If you're opening the account for a business that's less than a year old, some banks may ask for a business plan or proof of income, though this is less common for online applications.
The step-by-step process at most banks
Start by going to the bank's website and clicking the link for business checking. You'll enter your business type (sole proprietor, LLC, S-corp, C-corp, partnership, nonprofit, or other). The form then asks for your business name, the date you started, and your industry or business description.
Next, you'll enter your personal information: full name, date of birth, Social Security number or ITIN, and personal address. Then comes your business address. Some banks ask whether you own the building or rent it. You'll provide your phone number and email.
The bank will ask for your EIN or, if you don't have one, your state business registration number. If you have neither, some banks let you proceed with your Social Security number and add the EIN later. You'll confirm your expected monthly transaction volume—this helps the bank assign the right account tier and fee structure.
Finally, you'll review the account terms, agree to the bank's privacy policy, and submit. Most banks send a confirmation email within minutes. Your account number and routing number appear in your online dashboard immediately, though some banks delay access to the full platform for a few hours.
How long it takes to fund and use the account
Online-first banks like Mercury and Brex typically show your account as active within 30 minutes to 2 hours. You can see your account number and routing number right away and start receiving transfers. Some let you order a debit card during signup; it arrives in 3 to 7 business days.
Traditional banks usually take 1 to 3 business days to fully activate the account. Chase and Bank of America may show your account number the same day but hold it in a pending state until their verification team reviews your application. You can't transfer money or write checks until the account moves to active status.
If the bank requires an initial deposit, it typically must clear before you can use the account. A check deposit takes 3 to 5 business days; an ACH transfer from another bank takes 1 to 2 business days. Wire transfers are fastest—usually same-day or next-day. Some banks waive the initial deposit requirement if you're opening online.
Differences between online-first banks and traditional banks
Online-first banks (Mercury, Brex, Novo, Lemonade) are built for speed and simplicity. They finish the application in under an hour, charge lower monthly fees or no fees at all, and offer better integration with accounting software. The trade-off: they have limits on cash deposits (often $5,000 to $10,000 per month), no physical branches, and fewer services like business loans or merchant processing.
Traditional banks (Chase, Bank of America, Wells Fargo, Citibank) take longer to open an account but offer more services under one roof. You can deposit cash at a branch, talk to a banker about loans, and process merchant payments. Monthly fees are often higher ($15 to $35), and they may require a minimum balance. Their online platforms are sometimes slower and less intuitive than online-first banks.
Credit unions fall in the middle. They're often faster than big banks but slower than online-first banks. Fees are usually lower than traditional banks, and they may offer better rates on business loans. The downside: you must be a member (which may require living or working in a certain area), and their online platforms vary widely in quality.
What happens if the bank asks for more information
Some banks flag applications for manual review, especially if your business is new, your industry is high-risk (like cannabis or cryptocurrency), or your personal credit is poor. The bank will email you asking for additional documents. This usually means a copy of your business license, a recent bank statement from a personal account, or a utility bill showing your business address.
If the bank asks for these documents, upload them through the link in the email or log into your account dashboard. Don't email them directly unless the bank specifically asks you to. The review usually takes 1 to 3 business days. Some banks approve you conditionally—the account opens, but you can't make large transfers until they verify the documents.
If your application is denied, the bank will tell you why in writing. Common reasons are mismatched information (your name spelled differently on different documents), a mismatch between your personal address and business address, or a history of fraud or money laundering concerns. You can usually reapply after fixing the issue, but wait at least a few days before trying again.
Frequently Asked Questions
Do I need an EIN to open a business checking account online?
No. If you're a sole proprietor without employees, you can use your Social Security number. If you have an LLC, corporation, or partnership, you should have an EIN, but most banks let you use your Social Security number temporarily and add the EIN later within 90 days. You can get an EIN for free from the IRS website in about 15 minutes.
Can I open an account if my business is brand new and I haven't made any money yet?
Yes. Banks don't require proof of income for a new business checking account. They may ask about your expected monthly volume or your business plan, but this is informational. Some banks do ask for a business license or registration, so have that ready if you have it.
What if I'm a sole proprietor—do I still need a separate business account?
You're not legally required to, but it's strongly recommended. A separate account makes tax time easier, looks more professional to customers, and protects your personal assets if there's a legal issue. Most sole proprietors open a business checking account even if they're the only owner.
How much money do I need to open an account?
Most online banks require no minimum deposit to open. Some traditional banks require $100 to $500 as an initial deposit. A few banks waive the minimum if you set up direct deposit. Check the bank's website before you start the application—they list the minimum upfront.
Can I open a business checking account if I have bad personal credit?
Yes. Most banks don't run a hard credit check for business checking accounts. They may check ChexSystems (a banking history database) or run a soft credit inquiry, but a low credit score usually won't disqualify you. If the bank denies you, it's more likely due to a history of overdrafts, fraud, or closed accounts.
