EIN for a Michigan LLC: The Free IRS Process, Step by Step

An EIN for a Michigan LLC is free, takes roughly fifteen minutes, and comes directly from the IRS at irs.gov. There is no state fee, no federal fee, and no legitimate reason anyone should charge you hundreds of dollars for the number itself. If your LLC is already approved by LARA and you have a Social Security number or ITIN, you can have your EIN on screen before your coffee gets cold.

The rest of this guide covers what most “how to get an EIN” pages skip: whether you actually need one in the first place, exactly what the IRS application will ask you, how the answers interact with your Michigan filings, and what to do with the number once you have it.

First, make sure your LLC actually exists

Apply for the EIN after LARA approves your Articles of Organization, not before.

Michigan LLCs come into existence when the Articles of Organization are filed with the Department of Licensing and Regulatory Affairs under the Michigan Limited Liability Company Act (MCL 450.4101 et seq.). The filing fee is $50, submitted through the MiBusiness Registry Portal, with optional expedited service available — $50 buys 24-hour review if you need to move quickly.

Why the order matters: the IRS application asks for your LLC’s exact legal name and the state and date of formation. If you guess at a name that LARA later rejects as too similar to an existing entity, you end up with an EIN attached to a company that does not exist, and correcting it means writing letters to the IRS instead of clicking buttons. Wait for the approved Articles, copy the name character for character — including whether you used “LLC,” “L.L.C.,” or “Limited Liability Company” as required by MCL 450.4204 — and then apply.

If you’re still mapping out the sequence, the free 10-step Michigan LLC startup checklist lays out where the EIN falls relative to your operating agreement, bank account, and first annual statement.

When you actually need an EIN

Not every Michigan LLC is legally required to have one. Here is the honest breakdown:

Your situation	EIN required?	Why
Single-member LLC, no employees, no excise tax	No, strictly speaking	The IRS treats it as a disregarded entity; you can use your SSN on your Schedule C
Two or more members	Yes	Multi-member LLCs default to partnership taxation and must file Form 1065
You have (or will have) employees	Yes	Required for federal payroll tax deposits and W-2s
Electing S corporation or C corporation taxation	Yes	Form 2553 and Form 1120-S both require an EIN
Opening a business bank account	Practically yes	Nearly every Michigan bank and credit union asks for one on LLC accounts
Registering for Michigan sales tax or withholding	Practically yes	Treasury’s business registration is built around a federal EIN
Working with clients who issue 1099s	Practically yes	Lets you put the EIN on your W-9 instead of your SSN
Hiring 1099 contractors	Yes, in effect	You need one to issue 1099-NECs at year end

Notice the gap between “legally required” and “practically required.” A solo consultant in Grand Rapids with no employees could technically run on a Social Security number forever. Almost nobody does, for three reasons:

1. Banks. Chase, Huntington, Comerica, Lake Michigan Credit Union, and essentially every other institution will ask for an EIN when you open an LLC account. A dedicated business account is also the single most important habit for keeping the liability shield in MCL 450.4501 meaningful — commingling funds is the fastest way to invite a veil-piercing argument.

2. Privacy. Every client who pays you more than $600 gets a W-9. Do you want your Social Security number sitting in a dozen vendor files? Freelancers in particular should get an EIN purely to keep the SSN off paperwork — see the LLC guide for freelancers for how that fits with quarterly estimates.

3. Michigan tax registration. If you’ll collect Michigan’s 6% sales tax, withhold income tax from employees, or owe use tax, you’ll register with the Michigan Department of Treasury through Michigan Treasury Online. The registration is structured around a federal EIN, and having one in hand makes the process dramatically smoother.

Still deciding whether an LLC is even the right wrapper for what you’re doing? The comparison of a Michigan LLC versus a sole proprietorship covers the tradeoffs before you commit to either.

What to have ready before you open the application

The IRS online EIN Assistant times out after about fifteen minutes of inactivity and does not save partial progress. Gather this first:

• Exact legal name of the LLC as approved by LARA, plus any assumed name (DBA) you’ve filed
• Michigan business address — a street address works best; the IRS accepts a mailing address, but your registered agent’s address is not necessarily the right answer here, since the EIN notice is mail you want to receive yourself
• Responsible party’s name and SSN or ITIN. Since 2018 the responsible party must be a natural person — someone who actually controls or directs the entity — not another company
• Number of LLC members and the states where members reside
• Date the business started or was acquired (use your LARA formation date for a brand-new LLC)
• Closing month of your accounting year (December for nearly everyone)
• Expected number of employees in the next 12 months, if any
• A one-line description of your principal activity — “residential lawn care,” “freight trucking,” “wedding photography”

That last one is lower-stakes than people assume. It routes your file internally; it does not lock you into a line of business or create a licensing obligation.

The step-by-step IRS process

1. Go to irs.gov and search “Apply for an EIN Online.” Do not use a search engine result with “EIN” in the domain name unless you’ve verified it’s irs.gov. Look-alike sites are a thriving cottage industry.

2. Check the hours. The EIN Assistant runs Monday through Friday, roughly 7 a.m. to 10 p.m. Eastern. It is closed on weekends. Michigan is on Eastern time, so what you see is what you get.

3. Select “Limited Liability Company” as the entity type. The next screen asks for the number of members and the state — answer Michigan.

4. Answer the tax classification question. A single-member LLC will be told it’s treated as a disregarded entity by default and that no Form 8832 is required unless you want corporate treatment. A two-member LLC defaults to partnership. If you intend to elect S corporation status, you still get the EIN first and file Form 2553 separately afterward.

5. State your reason for applying. “Started a new business” is correct for a newly formed Michigan LLC. “Banking purposes” is also a legitimate option if that’s genuinely why you’re applying.

6. Enter the responsible party and their SSN or ITIN. One EIN per responsible party per day — if you’re forming several LLCs, space them out.

7. Enter the address and start date, then the activity description.

8. Choose how to receive the notice. Select the option to view and download the confirmation letter immediately. Save the PDF. Email it to yourself. Print a copy. This is your CP 575, and the IRS does not reissue it — the replacement they send later is a 147C letter, which works but takes a phone call and a wait.

Your EIN appears on screen at the end. It’s live for most purposes immediately, though it can take up to two weeks to propagate fully through IRS systems — which matters if you’re trying to e-file a return or make an electronic federal tax deposit right away.

If you can’t apply online

Method	Who it’s for	Typical turnaround
Online EIN Assistant	Responsible party has an SSN or ITIN	Immediate
Fax Form SS-4	No SSN/ITIN, or online app errors out	About four business days if you provide a return fax number
Mail Form SS-4	No rush, no fax access	Roughly four to five weeks
International phone line	Responsible party has no SSN/ITIN and no U.S. address	Same call, if you can reach an agent

Foreign owners of Michigan LLCs — and there are plenty, particularly in Detroit-area import/export and e-commerce — generally fall into the fax or phone path. Build the extra time into your bank-account timeline.

Why you should never pay for the number itself

Search “EIN application” and you’ll find sites that look official, use government-adjacent design, and charge a fee to type your information into the same free IRS form you could fill out yourself. Some of them are legitimate businesses selling convenience. Some are not. None of them can get you an EIN any faster than the IRS gives it to you for free, because the IRS issues it instantly either way.

Here’s our own position, stated plainly: we offer an EIN filing service because some clients want one less task on the pile, especially when they’re already having us handle formation. What you’re buying is our time and the certainty that the entity name, classification, and responsible party are entered correctly — not the EIN, which is and always will be free. If you have a Social Security number and fifteen free minutes on a weekday, do it yourself. We’ll tell you that before you pay us.

What’s genuinely worth comparing is total formation cost, since the EIN is one line item among several. The Michigan LLC cost calculator adds up the $50 Articles of Organization fee, the $25 annual statement, registered agent service, and expedite options so you can see the real number.

After you have the EIN

• Open the business bank account. Bring the EIN confirmation, your stamped Articles of Organization from LARA, and your operating agreement. Some banks ask for a Certificate of Good Standing; you can order one through the MiBusiness Registry Portal.
• Register with Michigan Treasury if you’ll collect sales tax, withhold payroll tax, or owe use tax. Michigan Treasury Online handles this.
• Calendar February 15. Every Michigan LLC files an annual statement with LARA by February 15 each year, with a $25 fee, under MCL 450.4207. The EIN has nothing to do with it, but it’s the deadline most new owners miss. If you’d rather not track it, our annual statement filing service handles the filing each year.
• File Form 8822-B within 60 days if the responsible party changes — a member buys out another, say, or control shifts.
• Don’t apply twice. If you’ve misplaced the number, call the IRS Business & Specialty Tax Line and request a 147C letter. Applying again creates a duplicate record and a mess.

Frequently Asked Questions

Does Michigan issue its own state tax ID number separate from the EIN? Michigan assigns you a Treasury account tied to your federal EIN when you register for sales tax, use tax, or employee withholding through Michigan Treasury Online. It isn’t a second number you apply for independently — the federal EIN is the anchor, and the state registration builds on it.

Can I get an EIN before LARA approves my Articles of Organization? Technically the IRS will issue one, but don’t. If your preferred name is rejected for being too similar to an existing Michigan entity, you’ll have an EIN tied to a company that never existed and you’ll need to correspond with the IRS in writing to fix it. Wait for approval, which is fast — standard review runs a few business days, and $50 buys 24-hour expedited processing.

I’m a single-member LLC with no employees. Is skipping the EIN a real option? Legally, yes — you can use your SSN for federal income tax purposes as a disregarded entity. Practically, you’ll hit a wall at the bank, on every W-9, and at Michigan Treasury registration, so most owners get one anyway. It costs nothing and removes future friction.

What if I convert my LLC to S corporation taxation later? You keep the same EIN. File Form 2553 with the IRS to make the election; the EIN doesn’t change because the entity doesn’t change, only its tax treatment does. You’d use the existing number on Form 1120-S and on payroll filings.

Do I need a new EIN if I add a member or change the LLC’s name? Adding a member changes your federal tax classification from disregarded entity to partnership, and the IRS generally expects a new EIN in that situation. A pure name change does not require a new number — you amend the Articles of Organization with LARA and notify the IRS of the name change.

If you’d rather have the Articles of Organization, registered agent, and EIN handled together so nothing falls through the cracks, start your Michigan LLC here. And if you’d rather do the EIN yourself on irs.gov after we file your formation — genuinely, that’s fine. It’s free for a reason.
