Do You Need a Separate Business Bank Account? In Plain Words
General information only — not tax or legal advice. This page reports, in plain words, what the U.S. Small Business Administration (SBA) and the Internal Revenue Service (IRS) say on their own pages listed below. It does not decide any reader’s situation.
What the two sources say about a requirement
The SBA says to open a business account when you are ready to start accepting or spending money as your business, and that a business bank account helps you stay legally compliant and protected, and provides benefits to your customers and employees. The SBA page does not state a law that requires a sole proprietor to have one.
The IRS, in Publication 583, uses “should” for the account: you should open a business checking account, you should keep your business account separate from your personal checking account, you should deposit all daily receipts in your business checking account, and you should use the business account for business purposes only.
The “must” in Publication 583 is about records, not about the account. It says: “Everyone in business must keep records.” It also says: “Except in a few cases, the law does not require any special kind of records. You can choose any recordkeeping system suited to your business that clearly shows your income and expenses.”
Side by side: sole proprietor vs. LLC or corporation
| Question | Sole proprietor | LLC or corporation |
|---|---|---|
| Does either source state a legal requirement to have a separate business bank account? | No. Neither the SBA nor the IRS states one. Both sources say “should,” as quoted above. | Neither source states a “must have a bank account” rule for these types either. The SBA instead links keeping funds separate to protection: “Business banking offers limited personal liability protection by keeping your business funds separate from your personal funds.” |
| Is the business separate from the owner? | No. The SBA says sole proprietorships do not produce a separate business entity, business assets and liabilities are not separate from personal assets and liabilities, and the owner can be held personally liable for the debts and obligations of the business. Publication 583 says the business has no existence apart from the owner, its liabilities are the owner’s personal liabilities, and the owner includes the income and expenses of the business on the personal tax return. | An LLC is formed under state law by filing articles of organization, and its members are not personally liable for its debts (Publication 583). The SBA says LLCs protect you from personal liability in most instances. A corporation is a legal entity that is separate from its owners (SBA), and the SBA says corporations offer the strongest protection to owners from personal liability and require more extensive record-keeping, operational processes, and reporting. |
| What number do the SBA’s opening documents list? | An Employer Identification Number (EIN), or a Social Security number, if you’re a sole proprietorship — that Social Security number option is listed by the SBA only for a sole proprietorship. | An Employer Identification Number (EIN). The SBA also says: “You can open a business bank account once you’ve gotten your federal EIN.” Publication 583 says EINs are assigned to sole proprietors, LLCs, corporations, and partnerships for tax filing and reporting purposes. |
| What does the IRS say about records? | The same record rules are stated for everyone in business. Good records help you monitor the progress of your business, prepare your financial statements, identify the source of your receipts — which you need to separate business from nonbusiness receipts and taxable from nontaxable income — keep track of deductible expenses, prepare your tax returns, and support items reported on your tax returns. You must keep your business records available at all times for inspection by the IRS. If the IRS examines any of your tax returns, you may be asked to explain the items reported, and a complete set of records will speed up the examination. For most small businesses, the business checkbook is the main source for entries in the business books. If you are in more than one business, you should keep a complete and separate set of records for each business. | |
| What benefits does the SBA list for business bank accounts? | The SBA lists these benefits for business bank accounts in general; it does not assign them to one business type. Protection: business banking offers limited personal liability protection by keeping business funds separate from personal funds, and merchant services offer purchase protection for customers and ensure their personal information is secure. Professionalism: customers can pay with credit cards and make checks out to the business instead of directly to the owner, and employees can be authorized to handle day-to-day banking tasks on behalf of the business. Preparedness: business banking usually comes with the option for a line of credit for the company, which can be used in an emergency or if the business needs new equipment. Purchasing power: credit card accounts can help a business make large startup purchases and help establish a credit history for the business. The SBA also says most business bank accounts offer perks that do not come with a standard personal bank account. | |
Kinds of business accounts the SBA names
Common business accounts include a checking account, a savings account, a credit card account, and a merchant services account. Merchant services accounts allow you to accept credit and debit card transactions from your customers.
What banks may ask for when you open an account
The SBA lists these as some of the most common documents banks ask for when you open a business bank account, and notes that some banks may ask for more:
- Employer Identification Number (EIN) — or a Social Security number, if you’re a sole proprietorship
- Your business’s formation documents
- Ownership agreements
- Business license
The SBA says opening a business bank account is easy once you have picked your bank, and that you can go online or to a local branch to begin the process.
Factors the two sources give you to weigh
This page does not rule on any reader’s case. The factors named by the SBA and the IRS are:
- Timing: the SBA ties opening the account to the point when a business starts accepting or spending money as the business.
- Separation and protection: the SBA describes limited personal liability protection from keeping business funds separate from personal funds, while also stating that a sole proprietorship itself does not produce a separate business entity.
- How customers pay: whether customers will pay by credit card or with checks made out to the business, and whether employees will handle day-to-day banking.
- Credit: whether the option of a line of credit for the company, and building a credit history for the business with a credit card account, matter to the business.
- Records: whether your records clearly show income and expenses, support the income, expenses, and credits you report, identify the source of receipts, and can be shown to the IRS if a return is examined — the duties Publication 583 states for everyone in business, with or without a separate account.
- Paperwork in hand: whether you have the documents the SBA lists that banks commonly ask for, shown above.
General information only — not tax or legal advice. This page is a plain-words summary of the SBA and IRS sources listed below. Neither source, as read for this page, states that a sole proprietor must by law have a separate business bank account; both use “should” for the account and “must” for keeping records.
