You need an Employer Identification Number (EIN) because federal law requires any business entity with employees, a partnership, a corporation, or certain types of LLCs to have one for tax administration. The legal basis is the Internal Revenue Code (Title 26), which mandates the use of an EIN for filing business tax returns, reporting employment taxes, and opening business bank accounts. For San Antonio restaurant owners, obtaining an EIN is a non-negotiable first step before applying for a Texas Food Service License or Alcoholic Beverage Permit with the Texas Alcoholic Beverage Commission (TABC). The issuing authority is the Internal Revenue Service (IRS), and this form (SS-4) is your formal application.
Operating without an EIN, or using your Social Security Number for business purposes, triggers immediate practical and legal consequences. The IRS enforcement is systematic, not discretionary. Key penalties include:
Legal code: Internal Revenue Code (Title 26)
Recent update: In 2025, the IRS implemented enhanced identity validation for online EIN applications to combat fraud, which may require the responsible party to have a U.S. Social Security Number or ITIN and a U.S. address for immediate online issuance.

See Full Requirements →Enter the city, state abbreviation (e.g., 'TX'), and ZIP code for the mailing address where you want to receive official IRS correspondence.
COMMON MISTAKE: Entering your home address here if it differs from the business's official mailing address; this is a common rejection reason that causes mail routing delays.
Enter the city, state, and ZIP code for the physical location of your restaurant business, which must match your state registration.
COMMON MISTAKE: Leaving this blank or entering a P.O. Box; the IRS requires a physical street address for the principal place of business, and using a mailing address here is a frequent rejection cause.
If you are applying as a sole proprietor with no employees (other than yourself), enter your nine-digit Social Security Number (SSN) here without hyphens or spaces.
COMMON MISTAKE: Entering an EIN instead of an SSN for a sole proprietorship, or incorrectly formatting the number with dashes, which the IRS system may flag as invalid.
Enter the two-letter state abbreviation (e.g., 'TX') where your corporation or LLC was legally formed and registered, which should match your Articles of Incorporation/Organization.
COMMON MISTAKE: Entering the state where the business operates ('TX') instead of the state where it was legally incorporated (e.g., 'DE'), which creates a mismatch with IRS records and causes rejection.
Check this box if your restaurant business is legally structured as a Limited Liability Company (LLC).
COMMON MISTAKE: Checking both 'Yes' and 'No' boxes for this question, which creates an inconsistency the IRS system will automatically reject.
Check this box if your restaurant business is NOT a Limited Liability Company (LLC).
COMMON MISTAKE: Incorrectly selecting 'No' for an LLC, which misclassifies the entity and leads to processing delays as the IRS attempts to reconcile the data.
Check this box if your LLC was organized under the laws of any U.S. state or the District of Columbia.
COMMON MISTAKE: Selecting 'Yes' for a foreign-organized LLC, which requires a different application process and supporting documentation, causing a full application rejection.
Check this box only if your LLC was organized under the laws of a foreign country.
COMMON MISTAKE: Selecting 'No' for a domestically organized LLC, which triggers requests for additional foreign entity documentation and significantly delays processing.
Check this box only if your business structure does not fit any of the specifically listed categories (e.g., a trust, estate, or other uncommon entity).
COMMON MISTAKE: Incorrectly selecting 'Other' for a common entity like an LLC or corporation, which leads to processing errors and requests for clarification from the IRS.
Check this box if your restaurant is structured as a nonprofit organization that is not a church, school, or other specifically listed type.
COMMON MISTAKE: Selecting this for a for-profit restaurant, which misrepresents tax status and can lead to penalties for filing under the wrong tax-exempt classification.

Entering your personal name (e.g., 'John Smith') as the 'Legal Name of Applicant' when you're registering a corporation, LLC, or partnership. This causes immediate IRS rejection because the EIN application must match the entity name on state formation documents. Always use the exact legal business name from your Articles of Incorporation or Organization.
Listing a corporate officer's address and SSN instead of the primary owner/principal's details. The responsible party must be a natural person (not the business itself) with a valid SSN/ITIN who controls or owns the entity. For an LLC owned by a single member, you are the responsible party; for a corporation, it's typically the principal officer. Mixing this up adds 1-2 weeks for a corrected application.
Entering a P.O. Box, registered agent address, or home address in fields requiring the physical location of your principal business. The 'Street Address' field requires the actual place of business operations (e.g., your restaurant's kitchen). Using a mailbox service address here is a common reason for processing holds.

Collect the business's legal name, trade name (DBA), principal address, and legal structure (e.g., LLC, Corporation, Sole Proprietorship). You will also need the social security number (SSN) or Individual Taxpayer Identification Number (ITIN) of the principal officer, general partner, or owner. Having the exact legal name from your formation documents and the responsible party's taxpayer ID ready is critical — mismatched names and IDs are a leading cause of IRS application rejections.
Fill out IRS Form SS-4, 'Application for Employer Identification Number.' The form has 19 fields covering business location, structure, reason for applying, and responsible party information. You can file online via the IRS's EIN Assistant on IRS.gov (fastest method), or by fax or mail. Online submission is immediate; fax can take up to 4 business weeks. Ensure the business start date and principal activity codes from the form instructions are accurate to avoid processing questions.
The IRS automatically validates the information provided against its records in real-time for online applications. For fax or mail submissions, this manual review occurs after receipt. The IRS checks for duplicate EINs under the same business name/entity and verifies the responsible party's taxpayer ID. Incomplete forms or mismatched owner/business name data will be rejected, requiring a new submission and restarting the timeline.
This is one of 13 requirements for opening a restaurant in Texas.

See All RequirementsProcessing time varies, but the IRS typically issues an EIN immediately if you apply online. If you mail Form SS-4, processing can take 4–6 weeks. Since this is a federal requirement, the timeline is the same regardless of your location in San Antonio, per the IRS application guide.
There is no government filing fee to obtain an EIN from the IRS — it is free. This $0–$0 cost is consistent nationwide, as confirmed on the IRS website. Not legal advice — verify with the IRS.
No, an EIN is permanently assigned to your business entity and cannot be transferred. If you move your business within San Antonio, you simply update your address with the IRS and state agencies. However, a change in business structure (like forming an LLC) requires a new EIN, which you can file using the Articles of Organization (LLC) or Articles of Incorporation (Corporation) requirement.
An EIN does not expire or require renewal. You use the same number indefinitely for federal tax purposes. However, you must keep your business registration active with local authorities, such as by renewing your City Business License/Registration annually, as required by the City of San Antonio.
There is no inspection for an EIN — it's a federal tax identification number obtained via paperwork. Inspections are for local operational permits, like the Certificate of Occupancy, which involves a city inspector verifying your building's safety and compliance. The EIN process is purely administrative, with no physical site visit.
