You don't legally need a business checking account, but mixing personal and business money creates real problems

A business checking account is not required by law. You can run a sole proprietorship or partnership using your personal bank account. However, the moment you start depositing customer payments or client invoices into a personal account, you blur the line between your money and your business money — and that blurring costs you in three concrete ways: it makes tax time harder because you have to manually separate business transactions from personal ones; it weakens your liability protection if you operate as an LLC or corporation, because commingling funds can make a court treat your business as an extension of your personal finances; and it makes it nearly impossible to understand whether your business is actually profitable, because you cannot see at a glance what money came in from customers versus what you spent on supplies.

The real question is not whether you need one, but whether the cost and effort of opening one is worth avoiding those three problems. For most people running any kind of business — even a part-time one — the answer is yes.

Key Takeaways

  • A business checking account costs between $0 and $30 per month depending on the bank and account type, and many banks waive the fee if you maintain a minimum balance or set up direct deposit.
  • Keeping business and personal money separate protects your liability shield if you operate as an LLC or S-corp, because courts look at whether you treated the business as a separate entity.
  • You will need an EIN (Employer Identification Number) from the IRS to open a business account, which takes about 15 minutes to request online and is free.
  • Banks require different documents depending on your business structure: sole proprietors need a driver's license and Social Security number, while LLCs and corporations need formation documents and an EIN.
  • Online banks and credit unions often charge less than traditional banks, but some do not offer business accounts or require higher minimum balances.

What separating your money actually protects you from

If you operate as a sole proprietor (you and your business are legally the same entity), a business account is mainly a bookkeeping tool. It makes your taxes cleaner and your profit calculation accurate, but it does not shield you from personal liability if someone sues your business.

If you operate as an LLC or S-corporation, the separation matters legally. These structures exist to protect your personal assets if the business gets sued or goes into debt. A court will honor that protection only if you treat the business as a separate entity — which means having a separate bank account, not paying personal expenses from business funds, and not paying business expenses from your personal account. If you commingle funds, a lawyer can argue to a judge that you never intended the business to be separate, and the court may "pierce the corporate veil," making you personally liable for business debts or judgments. A business checking account is the clearest evidence that you did treat the business as separate.

Even if you never get sued, the IRS looks at commingling as a red flag during an audit. The agency assumes that if you did not bother to keep the money separate, you probably did not keep good records either.

What you need before you can open an account

The documents required depend on your business structure. A sole proprietor needs only a driver's license and Social Security number — the same things you would use to open a personal account. Some banks will also ask for a business license, but many do not require it.

If you operate as an LLC or corporation, you will need your formation documents (the articles of organization or articles of incorporation filed with your state) and an Employer Identification Number (EIN) from the IRS. You can request an EIN free of charge at irs.gov/ein. The process takes about 15 minutes online, and you receive the number immediately. If you apply by phone or mail, it takes longer, but online is fastest. You do not need to have employees to get an EIN; it functions as your business's tax ID number whether you are a one-person LLC or a 50-person corporation.

Some banks will let you open an account with an EIN application number (the confirmation you receive when you apply) before the official EIN arrives in the mail. Others require the actual EIN. Call the bank before you go in, or check their website under "business accounts" or "small business banking."

How much a business account costs and what you get

Monthly fees range from $0 to $30 depending on the bank and the account tier. Many banks waive the fee if you maintain a minimum balance (often $500 to $2,500), set up direct deposit, or keep a certain number of transactions per month. Online banks and credit unions tend to charge less than brick-and-mortar banks, though some online banks do not offer business accounts at all.

What you get for the fee varies. Most business checking accounts include a debit card, online banking, bill pay, and the ability to deposit checks by phone or mobile app. Some accounts limit the number of deposits or withdrawals per month; others do not. A few banks charge per-check fees (typically $0.10 to $0.25 per check written) on top of the monthly fee, so read the fee schedule carefully.

If you expect to receive a lot of checks from customers, ask whether the bank offers remote deposit capture (the ability to photograph a check with your phone and deposit it without visiting a branch). If you will be making many transfers to other accounts, confirm that the bank does not charge for transfers or limits them per month. If you plan to accept credit card payments, some business accounts bundle merchant services at a discount.

The difference between a sole proprietor account and an LLC or corporate account

From a practical standpoint, the accounts work the same way. The difference is in what the bank requires to open it and how the IRS treats the money.

A sole proprietor account is opened in your personal name with your Social Security number, even though it is labeled "business." The bank may ask for a business license or DBA (Doing Business As) certificate, but many do not. On your tax return, business income and expenses flow through to your personal return on Schedule C.

An LLC or corporate account is opened in the business's name using the EIN. The bank will ask for formation documents to confirm the business exists and that you have authority to open the account. On your tax return, the business files its own return (Form 1120 for a C-corporation, Form 1120-S for an S-corp, or Schedule C if you have elected to be taxed as a sole proprietor), and you report your share of the profit or loss on your personal return.

The account itself functions identically. The main difference is that an LLC or corporate account makes it harder to accidentally commingle funds, because the account is in the business's name, not yours.

Where to open a business account and what to compare

You have three main options: a traditional bank (Wells Fargo, Bank of America, Chase, or a local bank), an online bank (Novo, Mercury, Brex, or others), or a credit union.

Traditional banks offer the most locations and the easiest access to a banker if you have questions, but they usually charge higher monthly fees and require higher minimum balances. Online banks typically charge less and have no minimum balance, but you cannot walk into a branch, and some do not accept checks by mail or offer all the services a traditional bank does. Credit unions often have the lowest fees and the most personalized service, but you have to be a member, which sometimes requires living or working in a specific area or belonging to a specific employer or organization.

When comparing, look at the monthly fee, any minimum balance requirement, per-check fees, transfer limits, and whether the bank offers the specific services you need (remote deposit, merchant processing, payroll integration, etc.). Many banks offer a free trial period or waive fees for the first few months, so you can test the account before committing.

When you might not need a separate business account

If you are a sole proprietor with very few transactions — for example, you freelance occasionally and receive only a handful of payments per year — the administrative burden of maintaining a separate account might outweigh the benefit. You can track business income and expenses in a spreadsheet and report them on Schedule C at tax time without a separate account.

However, even in this case, a business account costs little enough that it is usually worth opening. It takes the guesswork out of tax time, and it signals to the IRS that you take the business seriously. If you ever want to hire employees, apply for a business loan, or convert to an LLC, you will wish you had been keeping the money separate from the start.

Frequently Asked Questions

Can I use a personal account if I am a sole proprietor?

Yes, legally you can. But you will have to manually separate business transactions from personal ones at tax time, and you lose the liability protection that comes from treating the business as a separate entity. If you later convert to an LLC, the IRS may question why you did not have a separate account from the beginning.

Do I need a business account before I get my EIN?

No. You can request an EIN online at irs.gov/ein and receive it immediately. Some banks will open an account with your EIN application confirmation, but most require the actual EIN. If you are in a hurry, apply for the EIN online first, then open the account the same day.

What if my bank will not open a business account without a business license?

Try a different bank. Many banks do not require a business license for sole proprietors, and some do not require one for LLCs either. Online banks and credit unions are often more flexible. If you do need a license, you can obtain one from your city or county clerk's office, usually for a small fee and within a few days.

Can I have multiple business accounts at different banks?

Yes. Some people open one account for operating expenses and another for customer payments, or maintain accounts at multiple banks for redundancy. There is no limit, but each account will have its own monthly fee, so weigh the organizational benefit against the cost.

Will opening a business account affect my personal credit?

No. A business checking account does not appear on your personal credit report. The bank may do a soft credit check to verify your identity, but it will not lower your credit score.
