Business Bank Account Basics for Multi-Entity Firms in LA

You own six LLCs. Four hold properties, one runs the operating business, and one exists mostly because your accountant suggested it in 2019.

How many bank accounts do you have?

If the answer is fewer than six, you have a problem. And if money moves between those entities without documentation, you have a bigger one.

Most guidance on business banking addresses a single company keeping personal and business funds apart. That advice is sound and we have written about it separately. Running multiple entities creates a different set of risks, and the mistakes are less obvious.

Why Multi-Entity Banking Works Differently

A single business owner has one clear line to respect: personal money on one side, business money on the other.

Add entities and the lines multiply. Six entities means fifteen possible pairings, and every one of them is a boundary someone could argue you failed to observe.

The alter ego problem

You formed separate entities to contain liability. A claim against one property or one line of business should not reach the others.

Courts test whether that separation is real. If entities share a bank account, pay each other’s expenses casually, and keep no records of who owes whom, a plaintiff can argue they operate as a single enterprise. When that argument succeeds, the liability containment you paid for disappears.

The frustrating part is that this happens to owners with legitimate structures. The entities were formed properly, and the operating agreements are fine. Banking is what fails.

What courts actually examine

They look at behavior rather than paperwork. Separate accounts, separate books, documented transfers, and observed formalities all point toward genuine separation.

Shared accounts, undocumented money movement, and expenses paid by whichever entity happens to have cash point the other way.

Your bank statements are evidence. Think of them that way from the start.

One Account Per Entity, Without Exception

This is the rule, and it does not bend for convenience.

Every entity needs its own bank account, opened under its own name, with its own EIN. Not a sub-account under the parent. Not a nickname on a shared account. A separate account.

Why sub-accounts are not enough

Some banks offer sub-accounts or virtual accounts under a single master relationship. These help with internal tracking and they do not establish legal separation.

If the underlying account belongs to one entity, funds sitting in a sub-account still belong to that entity. Ask your banker directly whether each account is titled to the individual entity, because the answer determines whether the arrangement helps you.

The cost objection

Six accounts mean six sets of fees, six reconciliations, and six statements to review. That overhead is real, and owners resist it.

Compare the cost against what the accounts protect. If your entities hold meaningful equity or face genuine liability exposure, the annual banking cost is trivial next to the risk of consolidation.

If the overhead genuinely does not justify itself, the correct response is fewer entities rather than fewer accounts. An entity you cannot afford to maintain properly provides weaker protection than no entity at all.

Signatory authority

Each account needs a banking resolution documenting who may sign. Adopt it at the entity level and keep it with your records.

The same person can sign for multiple entities. What matters is that each entity authorized that person through its own governance.

Moving Money Between Entities

This is where most multi-entity owners create their exposure, and usually without realizing it.

Money frequently needs to move. The operating company covers a property expense. The holding company funds a new acquisition. One entity has cash and another has a payment due.

Moving the money is fine. Moving it without characterizing it is not.

Every transfer needs a reason

Each intercompany transfer should be one of three things, documented as such.

A loan. Papered with a note, an interest rate, and repayment terms. This is the most common and the most often skipped.

A capital contribution. Recorded in the receiving entity’s books as an increase in the contributing member’s capital account.

Payment for services or rent. Supported by an actual agreement and an invoice, at rates that reflect what an unrelated party would charge.

What undocumented transfers look like later

Picture a plaintiff’s attorney reviewing three years of statements. Money moves between entities monthly with no notes, no invoices, and no loan documents.

Their argument writes itself. If these entities do not respect their own boundaries, why should the court?

Documentation is not difficult. It is a written note or an invoice, created at the time. Reconstructing it years later is far harder and considerably less persuasive.

The management company structure

Many multi-entity owners run one entity that provides administrative services to the others. That entity employs staff, holds the software subscriptions, and invoices the operating entities.

This works well when the invoices are real and the rates are reasonable. It works poorly when the management company simply pays whatever bills arrive and nobody tracks which entity benefited.

What to Look For in a Bank

Not every bank handles multi-entity relationships well.

Multiple entities, one login

Ask whether their online platform lets you view and manage all entity accounts from a single login while keeping the accounts legally separate. Some banks do this cleanly and some require six separate logins, which is genuinely painful.

Fee structure across relationships

Some banks waive or reduce fees based on aggregate balances across related entities. Others charge each account independently.

Ask specifically. The difference across six accounts adds up.

A banker who understands the structure

Relationship banking matters more here than for a single-entity business. You will open accounts repeatedly as you form entities, and a banker who already understands your structure makes each one faster.

Community banks and regional banks often serve multi-entity real estate and holding company clients better than large national banks. That is worth exploring locally.

Account types you may need

Beyond an operating checking account per entity, consider reserve savings accounts for property entities, a payroll account if you employ staff, and merchant processing where the entity takes customer payments.

Keep them titled to the correct entity. A merchant account depositing into the wrong entity’s checking account creates exactly the confusion you are trying to avoid.

Documentation to Bring

Banks ask for more from entities than from individuals. Gather these before your appointment.

For each entity: Articles of Organization or Incorporation, the EIN confirmation letter from the IRS, the operating agreement or bylaws, a banking resolution authorizing account opening and signatories, and a current Statement of Information filing.

Also expect identification for every signatory and, frequently, for owners above a certain ownership percentage.

Beneficial ownership reporting

Federal beneficial ownership reporting requirements have changed materially in recent years, and banks have their own customer identification obligations that operate separately from any federal filing rule.

Confirm current requirements with your bank and your counsel rather than relying on guidance published a year ago. This area has moved quickly.

Good standing matters

Banks check entity status. An entity suspended for a missed Statement of Information or unpaid franchise tax may not be able to open an account at all.

That is one more reason entity maintenance is not optional busywork.

Expect the process to be slow

Opening six entity accounts takes longer than most owners plan for. Each one requires its own review, and banks handle entity onboarding far less efficiently than personal accounts.

Build in several weeks if you are forming entities and opening accounts ahead of a closing. Deals have been delayed because an acquisition entity could not receive funds in time.

Mistakes That Cost the Most

Five patterns show up repeatedly.

One account serving several entities. The single most damaging error. It undermines every entity in the group, not just one.

Paying entity A’s expenses from entity B. Convenient in the moment, and it accumulates into a pattern that looks like the entities are interchangeable.

Undocumented intercompany transfers. Money moving without a note, invoice, or contribution record.

Personal cards for entity expenses. Even with reimbursement, this blurs lines. Get a card per entity where possible.

Letting bookkeeping lag. Separate accounts with commingled books provide much weaker protection than you think. The records have to match the structure.

Skipping banking resolutions. Accounts opened without documented authority raise questions about whether the entity actually authorized the relationship.

Ignoring an entity you no longer use. A dormant entity with an open account and no bookkeeping is a liability rather than an asset. Either maintain it properly or dissolve it deliberately.

Depositing into whichever account is convenient. Revenue belongs to the entity that earned it, every time.

The common thread

Every one of these is a convenience decision made under time pressure. None feels significant on the day it happens, and the damage only appears years later when someone reviews the pattern rather than the individual choice.

Regulatory Obligations That Follow Each Entity

Multi-entity structures multiply compliance obligations, and banking is where the failures surface.

Each California entity owes the annual $800 franchise tax regardless of activity, plus any income-based LLC fee. Six entities means at least $4,800 annually before anything else.

Each entity needs its own EIN, files its own Statement of Information on its own schedule, and may need its own City of Los Angeles Business Tax Registration Certificate depending on where and how it operates.

If entities employ people, each employing entity needs payroll tax accounts with the Employment Development Department and its own workers’ compensation coverage.

Keep a single calendar tracking every deadline across every entity. Missed filings suspend entities, and suspended entities cannot bank, contract, or defend themselves.

Assign clear ownership

Someone has to own this calendar. In practice, obligations spread across several entities get missed precisely because everyone assumes another person is watching.

Name one person, whether internal staff, your bookkeeper, or outside counsel. Then review the full list quarterly rather than reacting to notices as they arrive.
