How to Register a Michigan LLP — Step by Step

Before anything gets filed, make sure the name you want is clear and follows Michigan's naming rules. LARA will reject a registration whose name conflicts with an existing entity or lacks the required designation, and a rejection means starting over.

Search the MiBusiness Registry business search for your proposed name and for close variations of it. You are looking for anything that reads or sounds so similar that the state would consider the names indistinguishable.

Naming rules for a Michigan LLP

• The name must contain a required designation identifying it as a limited liability partnership — the words "limited liability partnership" or an accepted abbreviation such as "LLP" or "L.L.P."
• It must be distinguishable from the names of other entities already on record with LARA.
• It cannot use words that imply a purpose the partnership is not authorized for, or that suggest a government agency.
• Words tied to regulated industries, such as banking or insurance, may require sign-off from the relevant Michigan regulator before the name can be used.

If your name is available but you are not ready to file, Michigan allows you to reserve it for a limited period so no one else claims it while you finish preparing. Our name search page covers availability and naming in more detail.

Michigan requires every LLP to name a resident agent with a registered office in the state, and you need that decided before you file — the agent's name and Michigan address go into the registration itself.

The resident agent receives service of process, meaning lawsuits and legal notices, along with official correspondence from LARA. The registered office must be a physical Michigan street address; a P.O. box alone does not qualify, and the agent must be available at that address during normal business hours.

Your options for a resident agent

• A partner: Any partner with a Michigan street address who is reliably available during business hours can serve. The trade-off is that their address becomes part of the public LARA record, and they must personally be available to receive documents.
• Another individual in Michigan: A trusted person, an employee, or an attorney with a Michigan street address.
• A commercial resident agent service: A company authorized to act as resident agent. It keeps a professional address in the public record instead of a partner's home, ensures someone is always present to accept legal documents, and forwards state mail to the partners.

For a professional practice whose partners are frequently with clients or in court, a commercial service is often the practical choice — it removes the risk that a summons arrives when no one is at the office.

The filing that gives your partnership LLP status is the registration submitted to LARA under the Michigan Uniform Partnership Act. You file it through the MiBusiness Registry portal. This is the step that turns on the partner liability shield.

The registration is a short document. It generally captures the partnership's name, the address of its principal office, the name and Michigan street address of its resident agent, and a statement that the partnership is electing limited liability partnership status. Michigan does not require you to disclose the internal economics of the partnership — how partners split profits or contribute capital stays private in your partnership agreement.

Processing

Michigan typically processes these filings in roughly seven to ten business days, though timing depends on LARA's workload and the filing channel. Once processed, the LLP appears in the state's records and your stamped confirmation is available. If you have a hard deadline — signing a lease, onboarding a client, opening an account — file with time to spare rather than assuming the fastest timeline.

An existing partnership converting to LLP status

If you are already operating as a general partnership and want to add the shield, you are not forming a new business — you are registering the existing partnership as an LLP. The partnership continues; the registration simply layers LLP protection on top going forward.

A partnership agreement is the internal governing document of your LLP. Michigan does not require you to file it with the state, and it never becomes public. But you should have a written one in place before the partnership starts doing meaningful business.

Without a written agreement, Michigan's default partnership rules under Chapter 449 fill every gap — and those defaults rarely match what a real set of partners intended. For example, the default rule generally splits profits equally regardless of who contributed more capital or does more work. A written agreement lets you set your own terms.

What a solid partnership agreement covers

• Capital contributions: What each partner put in and what future contributions may be required.
• Profit and loss sharing: The actual percentages, which need not be equal.
• Management and voting: Who decides what, and which decisions need unanimous consent versus a majority.
• Draws and distributions: How and when partners take money out.
• Adding and removing partners: The process for bringing in a new partner or handling one who leaves.
• Death, disability, or withdrawal: What happens to a departing partner's interest and how the partnership continues.
• Dissolution: The circumstances under which the LLP winds down and how assets are distributed.

Our partnership agreement page goes deeper on why this document matters for an LLP specifically.

An Employer Identification Number is a nine-digit federal tax ID the IRS hands out at no charge. A multi-member partnership needs one no matter what — the partnership files a Form 1065 return, and the EIN is how the IRS identifies the entity.

Why your LLP needs an EIN

• It is required to file the partnership's federal Form 1065 return.
• Banks require it to open a business account in the partnership's name.
• You need it to hire employees and handle payroll.
• It keeps partners' individual Social Security numbers off business paperwork.

How to apply

Head to the IRS EIN Assistant at IRS.gov and complete the online application. The application takes about ten minutes and issues the number immediately, so you can print the confirmation and use it the same day. The online application requires a responsible party with a U.S. Social Security number or ITIN. A responsible party without one can apply by fax or mail using Form SS-4. Our EIN guide covers the process for a partnership in detail.

Keeping partnership finances separate from every partner's personal money is not just good hygiene — it is part of respecting the LLP as a genuine entity. A dedicated account makes the pass-through bookkeeping cleaner and keeps distributions and contributions clearly documented.

What most banks want to open an LLP account

• The filed LLP registration confirmation from LARA
• The IRS EIN confirmation
• The partnership agreement, which many banks ask to review
• Government-issued ID for the partners who will be authorized signers

Decide up front who has signing authority and how the account is governed — many partnerships require two signatures above a certain dollar threshold. Setting that in your partnership agreement and mirroring it at the bank prevents disputes later.

The work of registering an LLP is front-loaded, but the status is not permanent on its own. Michigan expects the registration to be renewed on the state's schedule so the LLP designation — and the shield that comes with it — stays in force.

Renewal

Michigan LLPs file a renewal with LARA to maintain their status. Diarize the deadline the moment your registration is confirmed. Letting it lapse can cost the partnership its LLP status, which means losing the shield until it is restored. Our annual requirements page lays out the cadence.

Resident agent upkeep

If your resident agent moves, resigns, or you switch to a different one, file the change with LARA promptly. An out-of-date resident agent address leaves the LLP technically noncompliant even when everything else is current. See the change of resident agent page.

Taxes

Federally, the partnership files Form 1065 and issues K-1s to the partners. Each partner reports their share on their personal return. Michigan taxes the partnership income at the partner level. If the LLP sells taxable goods or provides taxable services, register with the Michigan Department of Treasury for the appropriate tax accounts.
