Why You Need a Application for Employer Identification Number
The Application for Employer Identification Number (EIN), also known as Form SS-4, is a federal mandate required by the Internal Revenue Service (IRS) under the authority of the Internal Revenue Code (Title 26). Its legal basis is found in IRC § 6011(b), which requires entities to identify themselves for tax purposes. While this is a federal requirement, obtaining an EIN is a foundational step for opening a restaurant in Tulsa, as Oklahoma state agencies and the City of Tulsa will not process your state sales tax permit (Oklahoma Tax Commission), business registration, or health department permits without it. The IRS is the sole issuing authority for EINs.
Operating your Tulsa restaurant without a valid EIN triggers immediate and compounding penalties. It blocks all other required licensing and exposes your business to severe financial and operational risks. Based on IRS enforcement data, the practical consequences of non-compliance include:
- Monthly Failure-to-File Penalties: A penalty of 5% of the unpaid tax per month, up to a maximum of 25% of the tax due, for not filing required returns (e.g., payroll taxes, Form 941).
- Monthly Failure-to-Pay Penalties: A penalty of 0.5% of the unpaid tax per month, on top of the failure-to-file penalty and accruing interest.
- Business Closure & Legal Action: You cannot legally hire employees, open a business bank account, or secure a lease. The IRS can pursue criminal prosecution for tax evasion or fraud, and the Oklahoma Tax Commission can issue a cease-and-desist order for operating without a sales tax permit.
- Insurance & Financing Voidance: Most commercial insurance policies and business loan agreements are contingent on having a legally established business entity with an EIN; operating without one can void coverage or trigger default.
Legal code: Internal Revenue Code (Title 26)
Recent update: As of 2026, the IRS continues to require that applicants for EINs have a valid U.S. Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), and the online EIN Assistant remains the primary method for immediate issuance.

Physical address - City, State, ZIP
textEnter the city, state, and ZIP code for the street location where your restaurant's principal business is conducted; this is your primary operating location.

checkboxMark this box with an 'X' if your business is *not* a Limited Liability Company (e.g., it's a corporation, partnership, or sole proprietorship).
COMMON MISTAKE: Marking both 'Yes' and 'No' boxes, which creates contradictory information and will cause the application to be rejected.
LLC organized in US? - Yes
checkboxIf you marked 'Yes' for LLC above, mark this box only if your LLC was formed under the laws of any US state or the District of Columbia.
COMMON MISTAKE: Marking this box if your LLC was formed in a US territory or a foreign country, which requires you to mark 'No'.
LLC organized in US? - No

checkboxMark this box only if your business is an estate, trust, government entity, or another type not explicitly listed in the other checkboxes on this form.
COMMON MISTAKE: Using this 'Other' box for a common entity type like an LLC or S-Corp, which has its own specific checkbox, causing misclassification.

Top 5 Application for Employer Identification Number Mistakes
1. Selecting the Wrong Legal Structure
Entering an incorrect entity type (e.g., selecting 'Sole Proprietor' when you've formed an LLC with the Oklahoma Secretary of State) creates a mismatch in the IRS's records. This can invalidate your EIN, requiring you to file a correction (Form 8822-B) and apply for a new number, adding 2-4 weeks to your setup timeline. Verify your official business structure with the state before starting the SS-4 form.
2. Using Your Personal Name as the Legal Name
A common error is using your personal name (e.g., 'John Smith') instead of the business's registered legal name (e.g., 'Smith's Grill, LLC'). This causes immediate rejection for corporations, LLCs, and partnerships, as the EIN must match the entity name on file with the state. Check your Oklahoma Secretary of State filing confirmation or assumed name certificate to get the exact legal name.
3. Inconsistent Principal Business Address
Providing a home address, PO Box, or an address different from the one listed in your state business registration creates processing delays. The IRS cross-references this information. For example, if your LLC is registered in Oklahoma with a Tulsa street address, but you list a Norman PO Box on the EIN application, it can trigger a manual review. Use the physical street address of your principal business location.

Gather Business Information & Confirm Your Need
Collect your legal business name (exactly as registered with the Oklahoma Secretary of State), physical address, business start date, and the name and SSN/ITIN of the principal officer (responsible party). Confirm you need an EIN—sole proprietorships with no employees or filing other federal returns may not. Applications are often delayed because the responsible party's information doesn't match IRS records, so double-check SSNs.
Submit Application Online via IRS Website
Complete the free online application on IRS.gov. The official form is IRS Form SS-4. You will answer a series of questions in an interview format. You must complete the session in one sitting. At the end, you will immediately receive your EIN confirmation letter (CP 575). Have all gathered information ready; pausing to find details is the #1 cause of session timeouts and restarting.
Or, Submit by Fax or Mail if Ineligible Online
If you cannot apply online (e.g., the responsible party lacks an SSN/ITIN), complete paper Form SS-4. For fax: send to the IRS business and specialty tax line at 855-641-6935. For mail: send to the Internal Revenue Service, Attn: EIN Operation, Cincinnati, OH 45999. Include a daytime phone number. Paper applications are processed in the order received, leading to significant delays compared to the online method.

See All RequirementsThe IRS does not publish a fixed processing timeline for EIN applications; it varies depending on application volume and the filing method used. Historically, online applications are processed immediately, while mailed SS-4 forms can take 4–6 weeks. Contact the IRS Business & Specialty Tax Line to confirm current processing times for your specific situation.
There is no government filing fee to obtain an Employer Identification Number (EIN) from the IRS. This is a federal requirement, and the cost is consistently $0 for all applicants, regardless of location. This differs from many local permits like a City Business License/Registration, which will have associated fees.
No, you cannot transfer an existing EIN to a new location. An EIN is permanently assigned to the specific business entity. If you move your business, you must update your address directly with the IRS using Form 8822-B, but you keep your original EIN. A significant business change, like converting to a corporation, may require a new EIN entirely.
An Employer Identification Number (EIN) does not expire and does not require renewal. Once assigned by the IRS, it is your business's permanent federal tax ID. You must, however, maintain related compliance, such as timely EFTPS Enrollment (Electronic Federal Tax Payment System) for submitting employment taxes.
There is no physical inspection for an EIN application. The IRS's review is a paperwork verification of the information submitted on Form SS -4 to confirm the legal entity's legitimacy. This contrasts with local operational permits, like a City Food License or Certificate of Occupancy, which typically involve on-site inspections by city officials.
