By Jake Lawson, LLC Formation Strategist
Getting an EIN for your Ohio LLC should cost exactly zero dollars and take about 10 minutes online. Yet I constantly meet entrepreneurs who paid $200+ to companies that simply filled out the same free government form you can complete yourself.
The confusion around EINs (Employer Identification Numbers) creates a perfect environment for scammers to prey on new business owners. They build official-looking websites, charge hefty fees, and provide nothing you can’t do yourself for free through the IRS website.
I’ve helped 300+ Ohio LLC owners get their EINs over the past decade, and I’m going to show you exactly how to do it right—plus the critical mistakes that can cost you time, money, and major headaches down the road.
What Is an EIN and Why Every Ohio LLC Needs One
An EIN (Employer Identification Number) is your LLC’s Social Security number for tax and business purposes. It’s a 9-digit identifier that the IRS assigns to your business entity for federal reporting and identification.
Don’t let the name confuse you: “Employer” doesn’t mean you need employees. Every legitimate business entity—even single-member LLCs with no employees—benefits from having an EIN.
Your Ohio LLC needs an EIN for:
- Opening business bank accounts (absolutely required)
- Filing federal tax returns
- Filing Ohio state tax returns (if applicable)
- Applying for business credit cards or loans
- Obtaining business licenses and permits
- Setting up payroll systems if you hire employees
- Building business credit separate from personal credit
- Professional credibility with vendors and clients
What an EIN is NOT:
- An Ohio state tax registration (that’s separate)
- Something issued by Ohio Secretary of State
- A business license or permit
- Proof that your LLC is legally formed
The EIN Scam Industry: Why People Pay for Free Services
Here’s the ugly truth: an entire industry exists to charge you for something the IRS provides free. These companies spend thousands on ads to appear in your search results, then charge $50-$300 for a 10-minute process.
Common EIN scam tactics:
- Websites designed to look like official government sites
- Claims that “professional assistance” is required
- “Expedited processing” fees (the IRS processes all EINs the same way)
- Scare tactics about “complicated government forms”
- Bait-and-switch pricing that adds fees during checkout
Red flags to avoid:
- Any website asking for payment before showing you the actual IRS form
- Claims that getting an EIN is “complex” or requires expertise
- “Express” services that cost extra
- Websites with URLs that aren’t IRS.gov
Jake’s rule: Never pay for free government services. The IRS EIN application is intentionally simple—you don’t need a middleman.
Ohio LLC EIN: Critical Timing Requirements
STOP: Do not apply for an EIN until your Ohio LLC is officially approved by the Ohio Secretary of State.
This is the most expensive mistake I see people make. Here’s the correct timeline:
Step 1: File Articles of Organization with Ohio Secretary of State
Step 2: Wait for approval (usually 1-3 business days for online filing)
Step 3: Verify your LLC appears in Ohio business records search
Step 4: THEN apply for your EIN with the exact approved LLC name
Why timing matters:
- EIN application must match your exact approved LLC name
- Name mismatches create banking and tax complications
- IRS verifies your business exists before issuing EIN
- Fixing mistakes later requires additional paperwork and delays
Exception: Professional formation services typically handle this timing correctly as part of their process.

Non-US Residents: Alternative EIN Process for Ohio LLCs
If you don’t have an SSN or ITIN, you can still get an EIN for your Ohio LLC, but you must use the paper process:
Form SS-4 by Fax or Mail:
- Download Form SS-4 from IRS.gov
- Complete all sections accurately
- Fax to: 855-641-6935 (faster processing)
- Mail to: IRS processing center (4-6 weeks processing time)
Important notes for non-US residents:
- You don’t need to hire a “third-party designee” (despite claims by service companies)
- Your Ohio LLC must be approved before submitting SS-4
- Include a cover letter explaining your non-US resident status
- Processing takes longer, so plan accordingly
Ohio-Specific EIN Considerations
Ohio State Income Tax
Unlike some states, Ohio has state income tax that affects your EIN usage:
- LLC income tax: Ohio taxes LLC income at entity level (different from many states)
- Pass-through taxation: Members also report LLC income on personal returns
- Commercial Activity Tax (CAT): Applies to LLCs with gross receipts over $150,000
- Municipal taxes: Many Ohio cities have local income taxes
Ohio Business Registration
Your federal EIN is separate from Ohio state business registration:
- Ohio Business Gateway: Register at business.ohio.gov for state tax purposes
- Different ID numbers: Federal EIN vs. Ohio state tax account number
- Required for most businesses: Ohio registration usually required regardless of income
- Timeline: Can register for Ohio taxes immediately after getting federal EIN
Banking in Ohio
Ohio has strong regional banking options for LLCs:
Recommended Ohio banks for business accounts:
- Huntington Bank: Strong Ohio presence, good small business support
- Fifth Third Bank: Regional focus, competitive business banking rates
- KeyBank: Extensive Ohio branch network, solid online banking
- Local credit unions: Often better rates and more personalized service
Common Ohio LLC EIN Mistakes (And How to Avoid Them)
Mistake 1: Applying Before LLC Approval
The problem: LLC name on EIN doesn’t match approved name
The consequence: Banks reject your EIN, tax filing complications
The fix: Wait for Ohio Secretary of State approval before applying
Prevention: Always verify LLC status in Ohio business records first
Mistake 2: Wrong Entity Type Selection
The problem: Choosing “Sole Proprietorship” instead of “LLC”
The consequence: EIN attached to you personally, not your LLC
The fix: Apply for new EIN with correct entity type, cancel old one
Prevention: Always select “Limited Liability Company” regardless of member count
Mistake 3: Incorrect Member Count
The problem: Confusion about single vs. multi-member classification
The consequence: Wrong tax treatment and filing requirements
The fix: Determine correct classification, may need new EIN
Prevention: Count all LLC owners, including spouses in non-community property states
Mistake 4: Name Mismatches with Ohio Records
The problem: EIN name doesn’t exactly match Ohio Secretary of State records
The consequence: Banking problems, potential tax issues
The fix: Apply for new EIN with exact name match
Prevention: Copy LLC name exactly from Ohio business records
Mistake 5: Losing EIN Documentation
The problem: Can’t locate EIN Confirmation Letter when needed
The consequence: Delays in banking, licensing, and tax filings
The solution: Request EIN Verification Letter (147C) from IRS
Prevention: Save multiple digital and physical copies immediately
Single-Member vs. Multi-Member Ohio LLCs
Single-Member Ohio LLCs
- EIN requirement: Technically optional, practically essential
- Tax treatment: Default “disregarded entity” (taxed like sole proprietorship)
- Ohio taxes: May still owe Ohio business taxes depending on income
- Benefits of EIN: Banking, privacy, identity protection, business credit
- Tax filing: Business income/expenses on personal tax return
Multi-Member Ohio LLCs
- EIN requirement: Mandatory under federal tax law
- Tax treatment: Default partnership taxation
- Ohio taxes: Entity-level tax plus pass-through to members
- Tax filing: Form 1065 partnership return plus individual K-1s
- Complexity: Usually requires professional tax preparation
Ohio LLC Banking After Getting Your EIN
Once you have your EIN, business banking becomes straightforward:
Required documents for Ohio banks:

Husband and Wife Ohio LLCs
Ohio is not a community property state, which affects tax options for married couples:
Available tax treatments:

- Corporate election: S-Corp or C-Corp taxation (complex, requires election)
NOT available in Ohio:
- Qualified Joint Venture: Only available in community property states

While technically optional, I strongly recommend it. You’ll need an EIN for business banking, and it provides privacy protection by keeping your SSN off business documents.
