Michigan LLC Business Bank Account: Exact Documents Banks Ask For

To open a Michigan LLC business bank account, nearly every bank in the state will ask for four things: a filed copy of your Articles of Organization stamped by LARA, your EIN confirmation from the IRS, a government-issued photo ID for every person who will sign on the account, and — if you have more than one member — your operating agreement. Some banks add a certificate of good standing, a banking resolution, or an assumed name certificate. That’s the whole list for most small LLCs, and if you walk in with those documents in a folder, you’re usually out the door with an account number in under an hour.

The second half of this article matters more, though. Opening the account is easy. Using it correctly is the part that determines whether the liability protection you paid $50 to LARA for actually holds up when someone sues you.

The document checklist, and why each item exists

Banks are not being difficult. Every request traces back to a specific federal or state obligation.

Document	Where it comes from	Why the bank wants it
Articles of Organization (filed copy)	LARA, via the MiBusiness Registry Portal	Proves the LLC legally exists and shows the exact legal name, entity ID, and formation date
EIN confirmation letter (CP 575) or Letter 147C	IRS	The account’s tax ID; banks report interest and are required to have a correct TIN on file
Photo ID for each signer	Michigan driver’s license, state ID, or passport	Customer Identification Program rules under the Bank Secrecy Act
Operating agreement	You (or your formation service)	Shows who has authority to open accounts, borrow, and sign — Michigan does not require one, but banks often do
Beneficial ownership certification	Bank form, filled out on the spot	FinCEN customer due diligence rules require banks to identify owners at 25% or more, plus one control person
Certificate of good standing	LARA, for a small certificate fee	Confirms your annual statements are current and the LLC is in active status
Assumed name (DBA) certificate	LARA filing	Required if you want to deposit checks written to a trade name rather than the legal LLC name
Banking resolution	Usually the bank’s own template	Written record that the members authorized this account and these signers
Occupational or trade license	State board, city, or county	Required by some banks for regulated trades — cosmetology, contracting, food service, childcare

A few notes on the items people get tripped up by.

The Articles copy has to be the filed version. A draft you typed yourself is not evidence of anything. After LARA processes your filing through the MiBusiness Registry Portal, you can download the stamped document with the file date and your entity ID. Standard online processing is included in the $50 Articles of Organization fee; the optional $50 expedited service returns the filing within 24 hours, which is worth it only if you have a closing, a lease signing, or a vendor onboarding deadline. If you want the full picture of what formation actually costs before the bank step, our Michigan LLC cost calculator breaks out the state fees from the optional ones.

The EIN confirmation is not optional, even for single-member LLCs. A single-member LLC with no employees is technically allowed to use the owner’s Social Security number for federal tax purposes. Banks almost universally refuse to open a business account that way, because the account name and the TIN won’t match. Get the EIN. It’s free from the IRS and takes minutes online, or you can have us handle the EIN application alongsideyour formation so the confirmation letter is in hand before you visit the bank.

Your legal name must match exactly. If LARA has you as “Great Lakes Fabrication L.L.C.” and you tell the banker “Great Lakes Fabrication LLC,” the systems may reject the match. Bring the stamped Articles and let the banker copy the name character for character from it, including punctuation.

Registered agent address ≠ business address. Banks ask for a physical street address for the business, and a commercial registered agent’s address will sometimes bounce their verification checks. This is one of several reasons to understand what your Michigan registered agent does and does not do for you — the agent receives service of process, not your mail from the bank.

Multi-member LLCs should expect real scrutiny of the operating agreement. Michigan’s LLC Act lets members structure management largely as they see fit (MCL 450.4308 and following), which means the bank has no way to know whether one member can unilaterally open accounts or whether two signatures are required. If your agreement is silent on banking authority, the bank will either require every member to sign or make you adopt a resolution. Fix this in the operating agreement instead.

Where Michigan owners actually open these accounts

There’s no single right answer, but the trade-offs are predictable.

• National banks with heavy Michigan branch networks — Chase, Fifth Third, Huntington, PNC, Comerica. Strong apps, broad ATM access, fast merchant services integration. Expect monthly maintenance fees waived only at a minimum balance or transaction volume, and expect a stricter document review at the branch.
• Michigan community banks — Independent Bank, Mercantile Bank of Michigan, Isabella Bank, and dozens of regional institutions. The underwriting relationship is the value here: if you’ll eventually want a line of credit, an equipment loan, or a commercial mortgage on a rental property, a local lender who knows your deposits is a real asset.
• Credit unions — Lake Michigan Credit Union, Michigan First, MSU Federal Credit Union and others offer business accounts. Often the lowest fees. Verify cash deposit limits and merchant processing options before committing if you run a cash-heavy operation.
• Online-only business banking platforms — no branch, no cash deposits (or awkward third-party workarounds), but fast onboarding and clean bookkeeping integrations. Fine for a freelance or e-commerce LLC, poor for a food truck or a salon.

Match the bank to your cash flow, not to the signup bonus. A food truck taking hundreds of dollars in small bills every night needs a branch with a night drop within a reasonable drive. A freelancer invoicing five clients a month via ACH does not.

Why commingling funds quietly destroys your liability protection

Here is the part most formation guides skip.

Michigan’s LLC Act is clear that members are shielded: under MCL 450.4501(4), a person who is a member or manager of an LLC is not liable for the acts, debts, or obligations of the company solely because of that status. That’s the whole point of forming an entity.

But that shield is not unconditional. Michigan courts will disregard the entity — “pierce the veil” — when a plaintiff shows that the LLC was a mere instrumentality of its owner, that the owner used it to commit a wrong or an injustice, and that the plaintiff suffered an unjust loss as a result. Courts look at a pattern of conduct, and the single most commonly cited evidence in that pattern is the failure to keep business and personal money separate.

Think about how this plays out practically. A tenant sues your rental LLC over a stairway injury. Their lawyer requests two years of bank statements in discovery. If the statements show the LLC’s checking account paying your mortgage, your Consumers Energy bill, your daughter’s tuition, and a Mackinac Island weekend — and show your personal account paying the LLC’s roofer and property insurance — the lawyer now has an exhibit arguing the LLC was never a real, separate business. It was your wallet with a name on it. At that point your house and personal savings are in play, and the $50 you spent at LARA bought you nothing. If you hold real estate, the mechanics of keeping that separation clean are worth reading in detail in our guide to using an LLC as a Michigan landlord.

Commingling rarely happens as one dramatic act. It happens because you left your business card at home and paid for lumber with the personal Visa, then never reimbursed yourself properly. Repeat that forty times and you’ve built the other side’s case for them.

The rules that keep the wall standing

1. Every dollar of revenue lands in the LLC account first. No Venmo to your personal account, no client checks deposited personally with a plan to “transfer it over.”
2. Every business expense leaves the LLC account. Use a debit or credit card in the LLC’s name. If you must front money personally, record it as a member contribution or a documented expense reimbursement, and actually process the reimbursement.
3. Pay yourself deliberately. For a single-member LLC taxed as a sole proprietorship, that’s an owner’s draw: a transfer from the business account to your personal account, labeled as such, on a predictable schedule. Not a card swipe at Meijer.
4. Never pay a personal bill from the business account. Not once. This is the single clearest red flag in a bank statement.
5. Capitalize the LLC adequately. Undercapitalization — running a business with essentially no money or insurance in it — is another factor courts weigh. Fund the account with a real opening contribution and carry appropriate liability coverage.
6. Keep the entity in good standing. File the $25 annual statement with LARA by February 15 each year. A dissolved or delinquent LLC is a gift to opposing counsel, and it will also block you from getting a certificate of good standing when your bank or lender asks for one. If the deadline is the kind of thing that slips, our annual statement filing service tracks it for you.
7. Sign as the LLC, not as yourself. Contracts, leases, and estimates should read “Great Lakes Fabrication LLC, by Jordan Reyes, Member,” not just your name.

None of this requires an accountant on retainer. It requires one account, one card, and the discipline to never mix them.

Your first two weeks, in order

1. File Articles of Organization with LARA and download the stamped copy ($50; add $50 if you need it in 24 hours).
2. Apply for the EIN and save the confirmation letter as a PDF.
3. Write or finalize an operating agreement that names who can open accounts and sign.
4. Order a certificate of good standing only if your chosen bank specifically asks.
5. File an assumed name certificate if you’ll operate under a trade name.
6. Call the branch, confirm their document list, and book an appointment — walk-ins often get turned away for business accounts.
7. Fund the account with a real opening deposit from your personal funds, recorded as a capital contribution.
8. Order the debit card and set up bookkeeping before the first transaction, not after.

Frequently Asked Questions

Can I use my personal checking account if I’m the only member? Legally nothing stops you, but it’s the fastest way to undermine the liability protection the LLC exists to provide. A plaintiff’s attorney who sees personal and business funds flowing through one account has a ready-made argument that the entity was never separate from you.

Does Michigan require a certificate of good standing to open an account? No state law requires it, but individual banks sometimes do, and lenders almost always will. You can order one from LARA through the MiBusiness Registry Portal for a small certificate fee once your annual statements are current.

How long after filing can I open the account? As soon as LARA has processed the Articles and you have your EIN. Standard online filings are typically processed within a few business days; the optional $50 expedited service returns them within 24 hours, and the IRS issues EINs immediately through its online application.

Do I need an operating agreement for a single-member LLC? Michigan doesn’t require one, but many banks ask anyway, and it’s cheap evidence that you treat the LLC as a distinct entity. It also lets you state clearly how contributions and distributions are handled — useful if you’re ever defending your separation of funds.

What if a client writes a check to my personal name instead of the LLC? Ask for a corrected check whenever possible. If that’s not practical, deposit it into the LLC account only if the bank will accept it, and document the transaction in your books as LLC revenue rather than routing it through your personal account.
