How to File a DBA for Your Michigan LLC: The CD-541 Assumed Name Filing

If you want your Michigan LLC to operate under a different public-facing name, you file a Certificate of Assumed Name — form CSCL/CD-541 — with LARA’s Corporations Division. That one filing is what most people mean when they say “DBA.” For a Michigan LLC, an assumed name filing is a state-level document (not a county one), it costs $25 per name, it stays effective until December 31 of the fifth full calendar year after you file, and it does not create a second company. Your LLC simply gains the legal right to sign contracts, open bank accounts, advertise, and get paid under a name that isn’t on your Articles of Organization.

That’s the mechanical answer. The more useful question is whether a second brand name belongs under your existing LLC at all — or whether you should be forming a second LLC. That decision has real cost and liability consequences, and it’s worth ten minutes of thought before you file anything.

What an assumed name actually does in Michigan

Under the Michigan Limited Liability Company Act (MCL 450.4101 et seq.), your LLC’s legal name is the one on file in your Articles of Organization. MCL 450.4217 is the section that lets an LLC transact business under a name other than that legal name, provided it files a certificate with the administrator — LARA.

A few consequences follow directly from that:

• You can hold more than one. There’s no cap. A single Michigan LLC can file five assumed names if it genuinely runs five brands. Each one is its own certificate and its own $25 fee.
• It’s a name, not an entity. There are no separate members, no separate operating agreement, no separate EIN, no separate liability shield. A lawsuit against “Riverbend Lawn & Snow” is a lawsuit against the LLC that owns that assumed name.
• LLCs file at the state level. This trips up a lot of Michigan owners, because sole proprietors and general partnerships file assumed names with the county clerk. If you have an LLC, the county clerk is the wrong office. Your filing goes to LARA.
• It has an expiration date. The certificate runs through December 31 of the fifth full calendar year following the year you file, and then must be renewed for another five-year term. Miss it and your right to that name on the state register lapses — which matters if you ever need to prove it in a contract dispute or to a bank.

When one LLC should run multiple brand names

The strongest cases for assumed names rather than new LLCs are situations where the risk profile and the ownership are identical, and the only thing that differs is marketing.

Good reasons to add an assumed name:

• Your legal name is too narrow. You registered “J. Okafor Enterprises LLC” and now you want to market as “Hastings Gutter Co.” A new LLC solves nothing; a DBA solves everything.
• Seasonal or service-line branding. A lawn care business that plows in the winter might run “Green Street Lawn” from April to October and “Green Street Snow Removal” from November to March. Same trucks, same insurance, same crew, same risk — one LLC, two names.
• Testing a new offer. You want “Michigan Drone Roof Inspections” live on a website and business cards before you know whether it’s a real business. An assumed name is a $25 experiment. A new LLC is a $50 filing plus a $25 annual statement forever and a second set of books.
• A separate e-commerce storefront. Many online sellers run a Shopify store, an Etsy shop, and an Amazon storefront under distinct brand names that all settle into one bank account and one tax return.
• You bought a business and want to keep its name. The goodwill lives in the old name; the liability and the contracts live in your LLC.

Reasons to form a second LLC instead:

• The two ventures have materially different liability exposure — a quiet bookkeeping practice and a commercial contracting operation with crews on roofs don’t belong in the same box.
• You have different partners or profit splits in each venture.
• You own real estate, which generally belongs in its own entity separate from any operating business.
• You intend to sell one brand someday. Selling an LLC is clean. Selling a DBA means carving assets out of a company that also does other things.
• A lender, franchisor, or license requires a standalone entity.

Michigan’s LLC Act doesn’t offer a general-purpose series LLC structure the way a handful of other states do, so in practice the choice really is binary: one LLC with multiple registered names, or multiple LLCs.

Side-by-side comparison

	One LLC + assumed names	Two separate LLCs
Cost to add the brand	$25 per assumed name	$50 Articles of Organization
Ongoing state cost	$0 extra (one $25 annual statement)	Second $25 annual statement every Feb 15
Renewal upkeep	Renew each name every 5 years	Annual statement forever, plus registered agent
Registered agent	Shared	Separate agent for each entity
Liability separation	None — one legal entity	Real, if you respect the formalities
Bank accounts	One account is fine; separate accounts optional	Separate accounts required
EIN	One EIN covers all names	Each LLC needs its own EIN
Tax filing	One return	Two returns (or two schedules)
Bookkeeping	Class/category tracking inside one set of books	Two complete sets of books
Selling the brand later	Messy — an asset sale	Clean — sell the membership interests

If you’re weighing the real all-in numbers, the Michigan LLC cost calculator will show you what a second entity actually adds over a few years once you count the annual statement, agent fees, and bookkeeping.

Filing the CD-541: a walk-through

The form is short — one page of substance — but a few fields are where filings get rejected.

1. Confirm the name is available. Search LARA’s business entity database before you fill anything out. Your assumed name must be distinguishable upon the records from every other entity name and assumed name already registered in Michigan. “Great Lakes Painting” and “Great Lakes Painting Co.” are generally not distinguishable enough. Note also that an assumed name can’t carry an entity designator that misrepresents what it is — don’t try to register “Northside Studios LLC” as an assumed name, because the assumed name isn’t itself an LLC.

2. Fill in the LLC’s exact legal name and identification number. Use the name precisely as it appears on the Articles of Organization, including punctuation and the “L.L.C.” or “LLC” ending. The six-digit ID number is on your filed Articles and in the online database.

3. State the assumed name. Write it exactly as you intend to use it on signage, invoices, and your bank account. Consistency matters later.

4. Sign as an authorized member or manager. Michigan accepts an electronic signature through the portal.

5. Pay the $25 fee. Expedited handling is available statewide as an add-on — $50 buys 24-hour review, with faster tiers priced higher. For an assumed name, standard processing is usually fine unless a bank or a client contract is waiting on it.

6. File it. The fastest route is the MiBusiness Registry Portal, LARA’s online filing system — the same place you file Articles of Organization and your annual statement. Online filings are processed in days rather than the weeks mailed documents can take. Mail and in-person filing at the Corporations Division in Okemos are still options.

7. Get a certified copy if a bank asks. Most Michigan banks will open a “DBA” sub-account on your existing business account once you show the filed certificate. Some ask for a certified copy, which LARA issues for an additional fee.

What an assumed name filing does not get you

This is where people get burned, so it’s worth being blunt.

It isn’t a trademark. Registering “Petoskey Pet Spa” with LARA stops another Michigan registered entity from registering a confusingly similar name on the state register. It does not stop a business in Ohio from using the name, it doesn’t give you rights against someone with earlier common-law use, and it doesn’t protect your logo. If the brand matters, look at a state trademark registration through LARA’s Corporations Division or a federal registration with the USPTO.

It isn’t a liability shield between your brands. If your cleaning business brand damages a client’s floors, the claim reaches every asset the LLC owns, including the equipment you bought for your other brand. Insurance, not a DBA, is what manages that.

It isn’t a tax event. One LLC, one EIN, one return. You don’t file a separate Schedule C per assumed name — though you absolutely should track each brand as its own income/expense class so you know which one is actually making money.

It doesn’t replace licensing. If your trade requires a state license, a city permit, or a sales tax registration, those obligations follow the activity, not the name. Check whether your licensing body wants the assumed name added to its own records too.

It doesn’t change your annual statement. Your LLC still files one $25 annual statement with LARA by February 15 each year, regardless of how many assumed names you hold. If that deadline tends to sneak up on you, read our guide to the Michigan LLC annual statement or hand it off through our annual statement filing service.

After the certificate is filed

A registered name that nobody can find isn’t worth much. Once the assumed name is on record:

• Claim the local listing. Each distinct brand with a distinct service area can support its own Google Business Profile, which is usually the single highest-return marketing move for a Michigan service business. Just make sure the brand genuinely operates as a separate business — Google penalizes duplicate listings for the same operation.
• Get the brand a home. A one-page site with the assumed name, service area, and phone number converts better than a social profile alone. If you’d rather not build it yourself, we handle business websites too.
• Update your paperwork. Invoices, contracts, and estimates should read something like “Riverbend Lawn & Snow, an assumed name of Okafor Outdoor Services LLC.” That one phrase keeps the liability shield visible and prevents a client from arguing they contracted with an individual.
• Calendar the renewal. Five years feels like forever until it isn’t. Put the December 31 expiration year in whatever system you actually check.

The $99 done-for-you option

If you’d rather not deal with name-availability checks, portal accounts, and a form that gets rejected for a mismatched entity ID, we file assumed name certificates for Michigan LLCs for $99 plus the $25 state fee. That includes the availability search against LARA’s records, preparation and electronic filing of the CSCL/CD-541, and the stamped certificate sent back to you for your bank. You can see that and everything else we handle on our services page.

It’s a filing you can genuinely do yourself — we’re not going to pretend otherwise. The $99 buys you the search done correctly and someone else absorbing the rejection-and-refile cycle if the name doesn’t clear.

Frequently Asked Questions

Do I need a separate EIN for my Michigan LLC’s assumed name? No. An assumed name is not a separate taxpayer, so your LLC’s existing EIN covers every brand it operates. If you don’t have an EIN yet because you’ve been using your SSN, our EIN filing service can get one issued for the LLC itself.

Can a Michigan LLC file more than one assumed name? Yes, with no statutory limit. Each name requires its own CSCL/CD-541 and its own $25 fee, and each runs on its own five-year renewal clock from the year it was filed.

I’m a sole proprietor with a county DBA. Does it transfer when I form an LLC? It does not. A county assumed name filing belongs to you as an individual; once you form an LLC, the name has to be re-registered at the state level under the LLC. Our walkthrough on how to start an LLC in Michigan covers the sequence, and the assumed name should be filed after the Articles are approved so you can reference the LLC’s ID number.

How long does LARA take to process an assumed name certificate? Online filings through the MiBusiness Registry Portal are typically processed within a few business days; mailed documents take considerably longer. If a bank or contract is waiting, the $50 expedited option moves your document into 24-hour review.

What happens if I let the assumed name expire? Your right to transact business under that registered name lapses at the end of the five-year term, and the name becomes available for another entity to claim. You can file a fresh certificate, but you’d be at the back of the line if someone else registered it first — so renew before the December 31 expiration.

Running two brands out of one Michigan LLC is usually the right call when the risk and the ownership are the same. When they aren’t, a second entity is cheap insurance. If you’ve decided which way you’re going and want the paperwork handled, start your filing here — assumed name, new LLC, or both.
