Yes, a sole proprietor can open a business bank account at most banks and credit unions. There is no federal law requiring you to keep business money separate from personal money, but a dedicated account simplifies tax reporting, gives clients a professional payee name, and creates a clean paper trail if the IRS ever audits you. To open one, you’ll need personal identification, a taxpayer identification number, and, in most cases, a “Doing Business As” certificate if you operate under any name other than your own.
Why Open a Separate Account at All
A sole proprietorship isn’t a distinct legal entity. Your business income, expenses, debts, and liabilities all belong to you personally, and the IRS treats sole proprietor income as your personal income, reported on Schedule C of your individual return. That’s exactly why a separate account helps. Without one, you’ll spend tax season sorting through months of mixed transactions, which invites errors and makes legitimate deductions harder to defend.
A dedicated account also matters during an audit. When every business dollar flows through its own account, the trail matches your filings. Mingling funds gives the IRS room to question whether a deduction is really a business expense. Beyond taxes, a business account lets you accept checks written to your business name, invoice from an account that looks the part, and track cash flow without guesswork.
What You Need to Bring
Federal law requires every bank to verify the identity of anyone opening an account. That obligation comes from the Bank Secrecy Act and Section 326 of the USA PATRIOT Act, which together require banks to maintain a written Customer Identification Program.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks For a sole proprietor, that means a mix of personal and business documents.
Personal Identification
Bring a valid, unexpired government-issued photo ID, typically a driver’s license or passport.1eCFR. 31 CFR 1020.220 – Customer Identification Program Requirements for Banks You also need a taxpayer identification number. For most sole proprietors, that’s your Social Security Number. If you have employees or file excise tax returns, you’ll need an Employer Identification Number from the IRS instead.2Internal Revenue Service.

A DBA Certificate If You Use a Business Name
If your business operates under any name other than your full legal name, the bank will require a “Doing Business As” certificate or trade name registration. You file this with a local county clerk’s office or state agency. Fees generally range from $10 to $100 depending on where you live, and some states also require you to publish the trade name in a local newspaper, which adds to the cost. The certificate proves you have the legal right to use that business name for commercial purposes.
Basic Business Information
Expect the bank to ask for your residential address, your business address, a description of your industry, when you started the business, and roughly how much you plan to deposit each month. Banks use these details to build a risk profile and monitor for unusual activity, as required by federal anti-money laundering rules.4FFIEC BSA/AML Manual.

Should You Use Your SSN or Get an EIN?
Sole proprietors without employees or excise tax obligations can legally use a Social Security Number for everything: bank accounts, tax filings, and contractor payments. But there are good reasons to apply for a free EIN anyway. Handing your SSN to every client and vendor raises the odds that someone uses it for identity theft or files a fraudulent return in your name. An EIN gives you a separate number for business use and keeps your SSN limited to personal matters.
Many banks also prefer, or outright require, an EIN to open a business account, even for sole proprietors. Applying is free and takes only a few minutes on the IRS website, and you receive the number immediately after completing the online application.2Internal Revenue Service.

How the Application Works
Most banks let you apply online or in person. Online applications typically involve uploading scans of your photo ID and DBA certificate, after which the bank verifies the information against public records. In person, a banker reviews your physical documents and enters them into the system.
During the process, you’ll sign a signature card, the bank’s official record of who is authorized to make transactions on the account. For a sole proprietorship, you’re the only authorized signer. You’ll also need to make an initial deposit to activate the account. The amount varies by bank but commonly falls between $25 and $100 for basic business checking, though premium tiers may require more.
Many banks activate accounts the same day, giving you an account number and routing number right away. Others take a day or two to finish background verification and set up online banking access, particularly if any document needs a second look.
Fees to Compare Before You Sign Up
Business checking accounts carry fee structures that differ from personal accounts, and the differences can be significant if your transaction volume doesn’t match the account tier.
- Monthly maintenance fees run from $0 to $50 depending on the bank and tier. Many banks waive the fee if you maintain a minimum balance or hit a monthly transaction threshold, and several online banks and credit unions offer no-fee business checking with no conditions.
- Cash deposit fees often kick in above a free monthly allowance, commonly $5,000 to $20,000, with a charge of about $0.30 per $100 deposited above the limit.
- Transaction caps on some accounts limit free monthly deposits, withdrawals, and transfers. Going over the cap triggers a per-transaction fee, often $0.25 to $0.50 each.
- Wire transfer fees commonly run $10 to $30 for incoming or outgoing wires. ACH transfers are generally free or low-cost, and the current per-payment limit for same-day ACH processing is $1 million.5Federal Reserve Services. Same Day ACH Resource Center
If your business handles mostly digital payments and little cash, a free online business checking account may be all you need. If you regularly deposit large amounts of cash, look carefully at the cash deposit allowance before you commit.
One Thing to Know About FDIC Coverage
Because your sole proprietorship isn’t a separate legal entity, the FDIC does not insure your business account separately from your personal accounts. It treats sole proprietorship deposits as your personal funds and combines them with any other accounts you hold individually at the same bank. Total coverage across all of them is $250,000.6FDIC. Financial Institution Employee’s Guide to Deposit Insurance – Single Accounts
So if you have $150,000 in a personal savings account and $150,000 in your sole proprietorship checking at the same bank, your combined deposits total $300,000, but only $250,000 is insured. Corporations, partnerships, and LLCs get their own separate insurance category. Sole proprietorships do not.7FDIC. Corporation, Partnership and Unincorporated Association Accounts If your combined balances get near the $250,000 limit, spread funds across multiple banks so each institution’s deposits stay inside the insured amount.
