You don't legally have to open a business bank account for an LLC, but doing so protects your personal assets and makes taxes simpler
An LLC (limited liability company) is a legal structure that separates your business from your personal finances. That separation only works if you actually keep them separate. Using your personal checking account for business deposits and expenses blurs the line between the two, and if your business gets sued, a court might decide your personal savings are fair game to cover the judgment.
A business bank account makes that separation clear and obvious. It also means your accountant doesn't have to dig through your personal transactions to find business ones, and the IRS can see at a glance that you're running a legitimate operation. Many business owners open one anyway because it's cheaper and faster than explaining to a lender or investor why they didn't.
Key Takeaways
- A business bank account is not legally required for an LLC, but it protects your personal assets if the business is sued.
- Mixing personal and business money can cause a court to ignore your LLC's liability protection in a lawsuit.
- A business account makes tax filing easier because all business transactions are in one place.
- Most banks require an EIN (Employer Identification Number) from the IRS before opening a business account, which takes a few days to get.
- Business checking accounts usually cost more per month than personal accounts but offer features like higher deposit limits and merchant processing.
What happens if you don't open a business account
If you run your LLC but deposit all income into your personal checking account and pay business expenses from the same account, you're not breaking any law. The IRS doesn't require a separate account. But you are taking on risk.
The main risk is called piercing the corporate veil. It means a court decides your LLC's liability protection doesn't apply because you didn't treat the business as separate from yourself. If someone sues your business and wins a judgment, they can go after your personal bank account, car, or house. A business bank account is the clearest evidence that you did treat the business as separate.
The second problem is practical: tax time becomes a mess. Your accountant has to sort through months of personal transactions to find the ones that belong to the business. That takes longer and costs more in accounting fees. A business account makes it obvious which transactions are business and which are personal.
How to open a business bank account for your LLC
Most banks follow the same basic steps. You'll need your LLC's legal name, an EIN from the IRS, and a government-issued ID. Some banks also ask for your LLC's operating agreement (the document that describes how your business is run) or a certificate of good standing from your state.
Start by getting an EIN if you don't have one. You can request one free from the IRS at irs.gov. It takes a few minutes online, and you get the number immediately. If you apply by phone or mail, it takes about two weeks.
Once you have an EIN, call or visit your bank. Most banks let you open a business account online, by phone, or in person. You'll provide your LLC's name, your EIN, your personal information, and how much you plan to deposit. Some banks require a minimum opening deposit (often $100 to $500). After you open the account, the bank will send you checks and a debit card, usually within 5 to 10 business days.
What documents you'll need to bring
Banks vary in what they ask for, but most want these items: your government-issued ID (driver's license or passport), your EIN documentation (the letter the IRS sends you, or a printout from irs.gov showing your EIN), and your LLC's legal name and formation documents (usually a certificate of formation or articles of organization from your state).
Some banks ask for an operating agreement, which is the document that describes how your LLC is managed. If you don't have one, ask the bank whether it's required or just preferred. Many banks will open an account without it, though some states recommend having one anyway for your own records.
If you're opening the account in person, bring originals or certified copies. If you're opening online, you'll upload scans or photos. Make sure the images are clear and all four corners of the document are visible.
Business checking account costs and features
Business checking accounts cost more than personal accounts. Monthly fees typically range from $10 to $30, depending on the bank and the account type. Some banks waive the fee if you keep a minimum balance (often $1,000 to $5,000) or set up direct deposit.
What you get for that fee varies. Most business accounts include unlimited check writing, a debit card, online banking, and mobile deposits. Some include merchant processing (the ability to accept credit cards), accounting software integration, or payroll services. Compare what each bank offers before you choose.
If you're just starting out and don't expect many transactions, some banks offer a basic business account with lower fees. As your business grows, you can upgrade to an account with more features.
When you might not need a separate account
If your LLC has no employees, makes very little money, and operates as a sole proprietorship (meaning you're the only owner), some accountants say a separate account is less critical. But even then, it's still a good idea. The cost is low, and the protection is real.
The only situation where you truly don't need a business account is if you're not actually running the LLC yet. If you formed an LLC but haven't started taking money or paying expenses, there's nothing to separate. Once you start doing business, open the account.
How a business account affects your taxes
A business bank account doesn't change how you file taxes. You still report your LLC's income and expenses on your personal tax return (unless you elect to be taxed as a corporation, which is a separate decision). But a business account makes it much easier to gather the numbers your accountant needs.
At the end of the year, your bank will send you a statement showing all deposits and withdrawals. Your accountant can use that statement to verify your income and expenses. Without a business account, you have to manually track which personal transactions were business-related, which is error-prone and time-consuming.
Some business accounts integrate with accounting software like QuickBooks or Wave, which automatically categorizes transactions as you make them. That saves even more time at tax time.
Frequently Asked Questions
Can I use a personal account for my LLC if I'm the only owner?
You can, but you shouldn't. Even as a sole owner, mixing personal and business money weakens your liability protection. A court might decide your LLC doesn't deserve protection because you didn't treat it as a separate entity. A business account costs $10 to $30 per month and is the clearest way to show you did.
What if I don't have an EIN yet?
Get one before you open the account. You can request an EIN free from the IRS at irs.gov in a few minutes, and you'll get the number immediately. Some banks will let you open an account with your Social Security number temporarily, but they'll ask for the EIN within a few days.
Do I need an operating agreement to open a business account?
Most banks don't require one, but some do. Call your bank and ask before you go in. If they require it and you don't have one, you can create a basic operating agreement online or ask a lawyer to draft one. It typically costs $100 to $300 if you hire someone.
Can I switch banks later if I don't like the one I choose?
Yes. You can close the account and open a new one at a different bank. The process is simple: open the new account, move your money, update any automatic deposits or payments, and close the old account. It usually takes a few days to a week.
What's the difference between a business checking account and a business savings account?
A checking account is for daily transactions — deposits, payments, and withdrawals. A savings account earns interest but limits how many withdrawals you can make per month. Most LLC owners use a checking account for operations and a savings account to hold emergency funds or money set aside for taxes.
