The bank account: where the wall actually gets built

Every legal protection an LLC offers is, in practice, downstream of one habit: company money and owner money never touch.

The exhibit list

A lawyer trying to pierce an LLC’s protection, the doctrine in piercing the veil, gathers evidence that’s almost always some version of the same list: personal expenses paid from the business account, business revenue landing personally, no paper trail explaining transfers.

The insight almost nobody separates from the CTA conversation

The anonymous LLC page covers the Corporate Transparency Act’s beneficial ownership reporting in detail. A separate, older requirement sits at the bank itself: since 2018, federal regulation has required banks to collect and verify beneficial ownership information directly at account opening, under the Customer Due Diligence rule, entirely independent of whatever’s been filed with FinCEN under the CTA. The two regimes use different thresholds and are enforced through different mechanisms, and a company can be compliant with one while stumbling on the other.

The second insight: the bank’s own defaults can quietly outrun the operating agreement

An operating agreement might specify that any single distribution or expenditure above a certain amount requires two members’ signatures, a real and common protective clause. Opening the business bank account, most banks default to a simple setup: any authorized signer can act alone on the account, full stop, regardless of what the company’s own governing document says internally, unless someone specifically requests and configures dual-signature requirements on the account itself, a feature many banks offer but essentially never volunteer. A company whose operating agreement was carefully drafted to require joint approval on large transactions, but whose bank account was opened with the default any-one-signer setup, has a real governance provision that exists on paper and does nothing at the actual point where money moves, because the bank was never told to enforce it. This gap is invisible until the exact day one member acts alone on something the agreement was specifically written to prevent.

What actually counts as separation

A separate account is necessary and not sufficient alone. Revenue in, expenses out, and any personal withdrawal treated as a documented distribution, covered in distributions.

The convenience-app trap

Paying a contractor through Venmo or Zelle from a personal account builds the exact same commingling pattern as a shared bank account.

What to actually do

Open the account before the company’s first dollar moves. Complete the bank’s beneficial-ownership certification accurately. If the operating agreement requires joint signatures on anything, ask the bank explicitly to configure the account to enforce it, rather than assuming the document alone does the job.
