No federal or state law explicitly requires your LLC to have a separate bank account — but mixing personal and business money is the most common evidence courts use to strip away your liability protection. A separate account costs little and protects everything the LLC was formed for.
What Is Commingling?
Commingling is mixing personal money and business money — paying your rent from the business account, depositing client payments into your personal account, or using the business card for groceries. A separate business bank account is an account held in the LLC’s name, used only for business income and expenses. Keeping the two apart is what makes the LLC a real, separate entity in practice, not just on paper.
Can Commingling Cost You Your Liability Protection?
Yes. “Piercing the corporate veil” is when a court ignores the LLC and holds the owner personally liable for the business’s debts. Commingling is the single most common piece of evidence courts look for when deciding whether to pierce the veil. If you treat the LLC’s money as your own, a court can decide the LLC was never really separate from you — and your personal savings, property and income become fair game for business creditors.
Single-member LLCs face extra scrutiny here. With only one owner, there is nobody else watching the money, so courts look harder at whether the owner respected the boundary between personal and business finances. A dedicated business account, used consistently, is your strongest defence.
What Does the IRS Say About Separate Accounts?
IRS Publication 583 advises businesses to keep business accounts separate from personal ones. Beyond the liability risk, mixing money creates tax problems: business expenses paid from a personal account are easy to miss or misdocument, and personal expenses paid from the business account are not deductible. If the IRS disallows deductions because your records are muddled, the accuracy-related penalty is 20% of the underpaid tax. Clean separation makes both your bookkeeping and any future audit far simpler.
How Do I Take Money Out of My LLC Correctly?
Never pay personal expenses directly from the business account. The correct way to take money out is a documented owner’s draw (for a single-member LLC) or distribution (for a multi-member LLC): transfer a set amount from the business account to your personal account, record it in your books, and then spend it personally. The transfer itself is not a business expense — it is a movement of your own money after the business has earned it.
What Will a Bank Ask for When I Open the Account?
Banks still ask for beneficial-owner identification — anyone who owns 25% or more of the LLC must be identified — even though the FinCEN beneficial-ownership (BOI) filing requirement for US companies has ended under the final rule of August 2026. Expect to provide your EIN, formation documents, operating agreement and ID. Approval is each bank’s own decision, and non-resident owners should expect extra verification steps — Mercury, Wise and Relay are common starting points, but no provider’s approval can be guaranteed.
