Business Banking Basics for Michigan Small Business Owners

The day your LLC is approved, one habit saves you more headaches than almost anything else: keep your business and personal money totally separate. Here’s how to set it up.

Rule #1 — Separate accounts, no exceptions

Once you have your stamped Articles of Organization and EIN, open a business checking account and route every dollar of business income and expense through it. No “I’ll just put it on my personal card this once.” Commingling is the most common reason a court can pierce an LLC — and it’s the difference between 20 minutes and two lost days at tax time.

What to open first

• Business checking — your day-to-day account. Look for low/no monthly fees, enough free transactions, and a solid mobile-deposit app.
• Business savings — your tax bucket. Move roughly 25–30% of every profit dollar here so quarterly taxes never catch you short.
• Business debit card — comes with checking, for everyday spend.
• Business credit card (soon) — builds business credit and separates spend. Pay it in full monthly.

Where to bank in Livingston County

You have three honest lanes:

• Local community bank or credit union (several around Howell and Brighton). Best for relationship lending and decisions made by people who know your business — valuable when you eventually want a loan or line of credit.
• Big national bank. Best for branch density, polished apps, and bundled payroll/merchant tools.
• Online business bank. Best for low fees and clean software — but no branch when you need to deposit cash or fix a problem in person.

For most new Livingston County owners, a local credit union or community bank with a good app is the sweet spot — relationship now, financing later.

What to bring to open the account

Call ahead for their exact list, but you’ll generally need your stamped Articles of Organization, your EIN letter, your operating agreement, and a personal photo ID.

Get paid like a pro

Set up a way to accept cards and send invoices (Square, Stripe, or QuickBooks Payments are common). Build the ~3% processing fee into your prices rather than absorbing it. And invoice the day the work is done — the fastest cash-flow lever a small business has is simply billing sooner.

Three habits that keep you out of trouble

1. Reconcile monthly. Match your books to your bank statement every month, not every April.
2. Pay yourself on a schedule. Take a regular owner’s draw instead of dipping in randomly.
3. Build a cushion. Work toward one to three months of operating expenses in savings — it turns a crisis into an inconvenience.

Frequently Asked Questions

Do I really need a separate bank account for my LLC?

Yes. It keeps your liability protection intact and your bookkeeping clean, and many banks prohibit running business activity through a personal account.

How much should I set aside for taxes?

A common rule of thumb is 25–30% of profit, kept in a separate savings account for quarterly estimated payments. Confirm your actual rate with a CPA.

What documents do I need to open a business account in Michigan?

Typically your stamped Articles of Organization, EIN letter, operating agreement, and personal ID. Call your bank for their exact list.

Local bank or online bank?

Local banks and credit unions win on relationship lending and in-person help; online banks win on low fees and software. Many owners use both.
