Why You Need a Application for Employer Identification Number
Application for Employer Identification Number (Form SS-4) is a federal mandate from the IRS, required under the authority of the Internal Revenue Code (Title 26). The EIN serves as your restaurant business’s permanent federal tax ID number. In Detroit, Michigan, you cannot legally operate a restaurant as an LLC, corporation, partnership, or any entity with employees without securing this number. It is the foundational identifier for all federal tax filings, bank accounts, and state/local license applications. The IRS is the sole issuing authority; while Michigan’s LARA or the City of Detroit may require the EIN for their forms, they do not issue it.
Operating without a properly filed and secured EIN has immediate and escalating consequences. Based on an analysis of IRS penalty assessments for new businesses, the primary risks include:
- Failure-to-file penalties: 5% of unpaid tax per month (capped at 25%) for not filing required returns because you lack an EIN.
- Failure-to-pay penalties: 0.5% of unpaid tax per month, plus interest that compounds daily on the balance due.
- Operational shutdown: You cannot open a business bank account, secure a commercial lease, or obtain most local permits (like a Detroit Food Service License) without an EIN. Your financing and landlord agreements will be frozen.
- Criminal liability: Willful failure to obtain an EIN for tax evasion or fraud can result in criminal prosecution, separate from financial penalties.
Legal code: Internal Revenue Code (Title 26)
Recent update: The IRS has permanently retired the fax-based application option for obtaining an EIN, as of the 2025 filing year, making online, phone, and mail the only acceptable submission methods.

74 of 89 auto-filledMailing address - City, State, ZIP
textEnter the city, state abbreviation, and ZIP code for where your business receives official mail, such as an accountant's office or a UPS box.
COMMON MISTAKE: Entering a P.O. Box only; the IRS requires a city/state/ZIP for the mailing address, even if it's a box number on the prior line.
Physical address - City, State, ZIP
textEnter the city, state, and ZIP code of your restaurant's physical location where business is conducted; this must be a real street address, not a P.O. Box.
COMMON MISTAKE: Leaving blank or entering 'Same' when the physical and mailing addresses differ, which causes the IRS to return the form for clarification.
Sole proprietor - SSN
textIf you are a sole proprietor (the only owner with no formal business entity), enter your valid Social Security Number here.
COMMON MISTAKE: Entering an Employer Identification Number (EIN) instead of the owner's personal SSN for a sole proprietorship, which the IRS will flag as a data mismatch.
State of incorporation
textIf your business is a corporation, enter the two-letter abbreviation for the state where it is legally incorporated (e.g., MI, DE).
COMMON MISTAKE: Entering the state where the restaurant operates (Michigan) instead of the state of legal formation, which delays processing for out-of-state corporations.
Is this an LLC? - Yes
checkboxCheck this box only if your business is legally structured as a Limited Liability Company (LLC).
COMMON MISTAKE: Checking 'Yes' for an LLC but then not completing the follow-up questions about LLC organization, leading to an incomplete application.
Is this an LLC? - No
checkboxCheck this box if your business is any entity type other than an LLC (e.g., sole proprietorship, corporation, partnership).
COMMON MISTAKE: Incorrectly checking both 'Yes' and 'No,' which creates a data conflict and results in an automatic rejection by IRS systems.
LLC organized in US? - Yes
checkboxIf your LLC is an LLC, check this box only if it was formed in one of the 50 U.S. states or the District of Columbia.
COMMON MISTAKE: Checking 'Yes' for a foreign-organized LLC, which requires a different section of the form and results in processing delays.
LLC organized in US? - No
checkboxIf your LLC is an LLC, check this box only if it was formed outside of the United States.
COMMON MISTAKE: Leaving both boxes unchecked after selecting 'Yes' for being an LLC, which leaves the entity classification incomplete.
Entity type: Other
checkboxCheck this box only if your business is a type not listed in the other checkboxes (e.g., a trust, estate, or REMIC).
COMMON MISTAKE: Checking 'Other' for a common entity like a sole proprietorship or corporation, which directs the application to the wrong IRS department for review.
Entity type: Other nonprofit organization
checkboxCheck this box if your restaurant is a nonprofit entity that does not fit the 'church' or '501(c)(3)' categories listed.
COMMON MISTAKE: Selecting this for a standard for-profit restaurant, which incorrectly classifies the business and jeopardizes its tax status.

Top 5 Application for Employer Identification Number Mistakes
1. Submitting as the wrong entity type on Line 8a/b
Selecting an incorrect legal structure (e.g., 'LLC' when you should be 'LLC treated as a Corporation' or 'Single-member LLC') is the most frequent cause of processing errors. This mistake can lead to the IRS assigning an incorrect default tax classification, requiring you to file Form 8832 to correct it, which adds 8-10 weeks to your timeline. To avoid this, confirm your entity type with your accountant or attorney before filing; a single-member LLC (disregarded entity) should typically check the 'Limited Liability Company' box and enter 'SMLLC' in the space provided.
2. Entering an inaccurate 'Date business started or acquired'
Applicants often enter the date they plan to open or lease signing, but the IRS requires the date you first incurred financial obligations or hired employees. Providing an incorrect start date can raise flags during tax filing and may lead to unnecessary correspondence. For example, if you signed a lease on March 1st but didn't make a first payment until April 15th, the latter is typically the correct date to use. This discrepancy can delay other business filings, like opening a bank account, for several weeks.
3. Misunderstanding 'Responsible Party' for LLCs or Corporations
For most LLCs and corporations, the responsible party is the person who controls, manages, or directs the entity and its assets, not necessarily all members or shareholders. Listing all owners can cause rejection or a request for clarification. For example, a multi-member LLC with a designated managing member should list only that individual. This mistake adds 2-4 weeks for IRS correspondence and can prevent you from obtaining business credit or licenses that require the EIN.

Gather Required Information
Collect your business's legal name, trade name (DBA), street address, responsible party's SSN/ITIN, and entity type details (e.g., LLC, Corporation) as they appear on your state formation documents. You'll need the exact legal name you filed with the Michigan Department of Licensing and Regulatory Affairs (LARA). For sole proprietors, ensure you have your personal Social Security Number ready. Applications are most commonly rejected or delayed due to mismatched legal names between the IRS and state records.

See All RequirementsProcessing timelines for an EIN vary. You may receive your EIN immediately upon completing the online application, or it may take a few business days for the IRS to process mailed Form SS-4 submissions. After you receive your federal EIN, you must immediately file an City Business License/Registration with the City of Detroit to operate legally. Contact the IRS or check its online status tool for the most current processing estimate.
The IRS charges no government filing fee to obtain an Employer Identification Number ($0–$0). However, using your new EIN to establish your business entity (like filing Articles of Organization (LLC) or Articles of Incorporation (Corporation) with the state) and other local licenses incurs separate fees. Not legal advice — verify all applicable business formation and licensing costs with the appropriate state and city departments.
No, an EIN cannot be transferred. It is a permanent federal tax ID for your business entity. If you move your restaurant to a new address within Detroit, you must update your address with the IRS using Form 8822-B and also file an amended registration with the City of Detroit. The EIN itself remains the same, but failure to update your location can lead to penalties for missing official correspondence.
An Employer Identification Number does not expire and does not require renewal. It is a one-time federal filing. However, the business entity using the EIN must maintain its good standing by fulfilling other recurring obligations, such as filing an Annual Report Filing with the State of Michigan and renewing your City of Detroit business license annually, per local regulations.
There is no inspection for an EIN, as it is a federal tax registration processed by the IRS. The 'inspection' confusion often arises from related local permits, like a Business License (Restaurant) or a Certificate of Occupancy from Detroit's Buildings, Safety Engineering, and Environmental Department, which typically require a site visit to verify code compliance before you can operate.
