Tolvern Business Account (emulated example) → Business bank account → Low-fee business checking → Clear deposit coverage
Answer in brief
An LLC should have its own business bank account. The IRS says to keep business checking separate from personal checking, and the SBA ties separate funds to limited personal liability protection.

Do I need a business bank account for an LLC?
Yes, in practice. IRS Publication 583 says opening a business checking account is one of the first things to do when starting a business, and that it should be kept separate from your personal account and used for business purposes only.
The SBA names limited personal liability protection as one of the benefits of keeping business funds separate from personal funds, and says to open a business account once you start accepting or spending money for the business.
What mixing funds puts at risk
The SBA says LLCs protect owners from personal liability in most instances, though not in every case. Running the company's money through your own account undercuts the separation you formed it to create. How a court would treat a particular mix of funds turns on state law and the facts, so talk to a lawyer if you have already mixed accounts.
Liability by structure. Source: SBA, choose a business structure.
| Structure | SBA description of owner liability | Banking consequence |
|---|---|---|
| Sole proprietorship | Unlimited personal liability; no separate business entity | Separate account is for clean records |
| LLC | Owners are not personally liable, in most instances | Separate account supports the structure |
Does a single-member LLC need its own EIN for banking?
The IRS treats a single-member LLC as a disregarded entity for income tax unless it elects otherwise, with income reported on the owner's return. That is a tax rule and gives you no reason to use your personal account. The same IRS page says a single-member LLC that does not otherwise need an EIN can still get one if it needs one to open a bank account.
An EIN is free from the IRS, and the IRS says it can be used immediately for most business needs, including opening a bank account.
How is an LLC insured at the bank?
Under the FDIC's guide, an LLC formed under state law is within the corporation category, with coverage of up to $250,000 if it is engaged in an independent activity. That coverage is separate from the owner's personal deposits, unlike a sole proprietor's position.
If you already mixed funds
Open the account and stop paying business costs personally. Then go back through every past transfer between you and the company and label it a contribution, a distribution or a loan. IRS Publication 583 advises noting the source of each deposit, including personal funds and loans. Your accountant can tell you how to treat the history.
