Application for Employer Identification Number (2026)
Without an Employer Identification Number (EIN), you cannot legally hire employees, open a business bank account, or file federal tax returns—and the IRS will not recognize your restaurant as a separate legal entity. The Application for Employer Identification Number (Form SS-4), issued by the Internal Revenue Service, is the federal filing that assigns your unique business tax identifier. Also called an EIN application or FEIN request. This form contains 89 fields, but ApronPrep auto-fills 74 of them based on your restaurant details—eliminating manual data entry and rejection-causing errors. There are no government filing fees for this application. Most applicants complete this in under 15 minutes with ApronPrep, which auto-fills 74 of 89 fields.

Why You Need a Application for Employer Identification Number
The Employer Identification Number (EIN) — also called a Federal Tax Identification Number — is required under the Internal Revenue Code (Title 26), administered by the Internal Revenue Service (IRS). Any restaurant that hires employees, operates as a partnership or corporation, files employment or excise tax returns, or withholds taxes on non-wage income paid to a non-resident alien is legally required to obtain an EIN before conducting those activities. Without it, you cannot open a business bank account, execute a payroll, apply for most state and local business licenses, or complete the paperwork your landlord and lender will request at closing. The IRS does not issue retroactive EINs — operating without one puts every prior transaction at legal risk.
The consequences of failing to obtain or properly use an EIN compound quickly. The IRS enforces the following penalties under Title 26:
- Failure-to-file penalty: 5% of unpaid taxes per month, up to a maximum of 25% of the total amount owed
- Failure-to-pay penalty: 0.5% of unpaid taxes per month, accruing separately from the failure-to-file penalty
- Interest charges: Assessed on all unpaid tax balances from the original due date, compounding daily at the federal short-term rate plus 3%
- Payroll and banking blocks: Banks and payroll processors will freeze or refuse accounts that lack a valid EIN on file
- Lease and insurance complications: Commercial landlords and business insurance carriers routinely require an EIN as part of the entity verification process — missing this delays or voids those agreements
- Criminal prosecution: Willful failure to file or fraudulent use of a tax identification number can result in prosecution under 26 U.S.C. § 7201 and § 7203, carrying potential fines and imprisonment
Not legal advice — verify current requirements directly with the IRS or a qualified tax professional.
Legal code: Internal Revenue Code (Title 26)
Recent update: As of 2024, the IRS requires that all EIN applications submitted by mail or fax include a responsible party with a valid individual Taxpayer Identification Number (SSN or ITIN) — third-party nominees can no longer be listed as the responsible party on Form SS-4, a policy first enforced in 2021 and still in effect for 2026 filings.
Who Needs a Application for Employer Identification Number?
| Type | Required | Notes |
|---|---|---|
| Restaurant (Full-Service) | Required | Any full-service restaurant that pays wages, operates as a partnership, corporation, or LLC, or opens a business bank account must obtain an EIN from the IRS under Internal Revenue Code § 6109 — sole proprietors with no employees are the only exception, and virtually all full-service restaurants have at least one employee. |
| Bar / Nightclub | Required | Bars and nightclubs are required to obtain an EIN because they universally employ staff (bartenders, security, servers) and must report tip income and payroll taxes to the IRS under IRC § 3402, making an EIN mandatory for all payroll filings. |
| Food Truck | Required | Food trucks operating as an LLC, partnership, or corporation, or those with any employees, must obtain an EIN per IRC § 6109; even a sole-proprietor food truck owner with no employees will typically need an EIN to open a business bank account or apply for a vendor permit. |
| Coffee Shop / Café | Required | Coffee shops and cafés that employ baristas or other staff — which covers nearly all brick-and-mortar locations — are required to have an EIN for federal payroll tax withholding and reporting under IRC § 3402 and § 6109. |

74 of 89 auto-filledMailing address - City, State, ZIP
textEnter the city, two-letter state abbreviation, and 5-digit (or 9-digit ZIP+4) ZIP code for the address where the IRS should send correspondence — this can be a P.O. Box city or a third-party address if you use one.
COMMON MISTAKE: Entering only the ZIP code without the city and state, or using a full state name instead of the two-letter USPS abbreviation (e.g., 'California' instead of 'CA'), which causes IRS processing errors.
Physical address - City, State, ZIP
textEnter the city, two-letter state abbreviation, and ZIP code for the actual physical location of your business — the IRS uses this to verify your business exists at a real street address and cannot be a P.O. Box.
COMMON MISTAKE: Copying the mailing address city/state/ZIP here when the physical location differs, or entering a P.O. Box ZIP that does not correspond to a street address — the IRS cross-references this against business registration records.
Sole proprietor - SSN
textEnter the 9-digit Social Security Number of the individual sole proprietor in the format XXX-XX-XXXX — the IRS requires this to link the EIN to the owner's personal tax record under IRC § 6109.
COMMON MISTAKE: Entering an Individual Taxpayer Identification Number (ITIN) or an existing EIN in this field instead of a valid SSN — the IRS will reject the application because sole proprietors must have an SSN as the responsible party identifier.
State of incorporation
textEnter the two-letter USPS abbreviation for the U.S. state (or 'DC' for the District of Columbia) where your entity was legally incorporated or organized — this must exactly match your Articles of Incorporation or Certificate of Organization on file with that state.
COMMON MISTAKE: Entering the state where the business operates rather than the state where it was legally formed (e.g., entering 'CA' for a Delaware-incorporated entity operating in California), which creates a mismatch with IRS entity records.
Is this an LLC? - Yes
checkboxCheck this box only if your entity was legally organized as a Limited Liability Company under state law — checking 'Yes' triggers additional LLC-specific fields the IRS requires to determine your federal tax classification.
COMMON MISTAKE: Checking 'Yes' for a corporation or partnership that has 'LLC' informally in its name but was not formally organized as an LLC under a state LLC statute — always verify against your state formation documents.
Is this an LLC? - No
checkboxCheck this box if your entity is not a Limited Liability Company — for example, a sole proprietorship, corporation, partnership, or nonprofit organized under a non-LLC state statute.
COMMON MISTAKE: Leaving both the 'Yes' and 'No' LLC checkboxes unchecked, which causes the IRS to return the application as incomplete since this is a required field when an entity type is selected.
LLC organized in US? - Yes
checkboxCheck 'Yes' if your LLC was formed under the laws of any U.S. state, the District of Columbia, or a U.S. territory — this field only appears if you answered 'Yes' to the LLC question above.
COMMON MISTAKE: Checking 'Yes' for a foreign LLC that was domesticated in a U.S. state but originally formed abroad — domestication status can affect federal tax treatment, so confirm your formation jurisdiction with your registered agent.
LLC organized in US? - No
checkboxCheck 'No' only if your LLC was formed under the laws of a foreign country — this triggers different IRS classification rules and may require additional foreign entity documentation under Treasury Regulation § 301.7701-3.
COMMON MISTAKE: Checking 'No' for a U.S.-formed LLC simply because the owners are foreign nationals — the organized-in-US question refers to the jurisdiction of legal formation, not the nationality of the members.
Entity type: Other
checkboxCheck this box if your entity does not fit any of the specifically listed entity types on the form — you must also write in the specific entity type on the adjacent line (e.g., 'governmental entity' or 'Indian tribal government').
COMMON MISTAKE: Checking 'Other' without completing the required write-in description of the entity type, causing the IRS to return the application for clarification and adding weeks to your processing timeline.
Entity type: Other nonprofit organization
checkboxCheck this box if your organization is a nonprofit entity that does not qualify as a church or church-controlled organization, a tax-exempt organization under IRC § 501(c)(3), or another specifically listed nonprofit type.
COMMON MISTAKE: Checking 'Other nonprofit organization' for an entity that is actually applying for 501(c)(3) status — if you intend to pursue tax-exempt status, your entity type selection here affects which IRS filings you will need to complete subsequently.

Top 5 Application for Employer Identification Number Mistakes
1. Selecting the Wrong Entity Type
Based on ApronPrep's analysis of Application for Employer Identification Number applications, the single most frequent error is checking the wrong 'Type of Entity' box on Line 2 — for example, selecting 'Sole Proprietor' when the restaurant is actually organized as an LLC or S-Corporation. The IRS uses this selection to determine your tax filing obligations, and getting it wrong can cause your EIN to be linked to the wrong tax classification, requiring a corrections process that can add 4–6 weeks to your timeline. Before you file, confirm your entity type against your state formation documents (e.g., your Articles of Organization or Incorporation) and match it exactly to the SS-4 line options.
2. Entering the Responsible Party's SSN/ITIN Incorrectly
Line 7b requires the Social Security Number or ITIN of the 'responsible party' — the individual who owns or controls the entity — and transposing even one digit causes the IRS to reject the application outright with an error code that requires re-filing from scratch. A common example: entering a spouse's SSN instead of the primary owner's, or using an old ITIN that has since been superseded. Double-check the nine-digit number against a physical Social Security card or ITIN assignment letter before submitting, and confirm the responsible party matches the name on Line 7a exactly.
3. Using a P.O. Box as the Business Address When a Street Address Is Required
The SS-4 form has separate fields for the mailing address (Line 4a–4b) and the business's physical location (Line 5a–5b) — applicants frequently enter a P.O. Box in both fields, which the IRS flags because a physical street address is required to validate the business location. For a restaurant, this should be the actual address of the establishment, not the owner's home address or accountant's office. If your restaurant location is not yet finalized, use your legal registered agent's street address for Line 5a and note the anticipated address in Line 18 (Other).
Timeline: Varies
Gather Required Information
Collect your Social Security Number (or Individual Taxpayer Identification Number if you're a non-U.S. citizen), business structure documentation (partnership agreement, articles of incorporation, or sole proprietorship registration), and your expected business start date. Have your business name, principal business address, and the names/SSNs of all owners or responsible parties ready. This step typically takes 30 minutes — most delays happen here because applicants don't have all owner SSNs on hand.
Complete IRS Form SS-4 (or Apply Online)
Fill out IRS Form SS-4 (Application for Employer Identification Number) with your business details. The form has 21 numbered lines and takes 15–20 minutes with all information ready. Alternatively, apply online through the IRS Business Services Online portal (BSO) at irs.gov — this method issues your EIN immediately upon approval. Online applications are processed in real-time; paper applications take longer. ApronPrep auto-fills your business name, address, and owner information on the form if you've already provided it during your restaurant compliance setup.
Submit Application to IRS
Submit Form SS-4 through one of three channels: (1) Online via IRS Business Services Online portal — fastest option, approval instant; (2) By phone to the IRS Business & Specialty Tax Line (1-800-829-4933) — available Monday–Friday, 7 a.m.–7 p.m. ET, approval takes 5–10 minutes; (3) By mail to the IRS address listed on Form SS-4 instructions — allow 4–6 weeks for processing. The IRS charges no filing fee for an EIN application. Most restaurant owners choose online or phone submission to avoid delays.

See All RequirementsThe IRS processes EIN applications immediately if you apply online via their website, or within 4 business days if you submit Form SS-4 by fax or mail, per the IRS EIN application guide. Most restaurants receive their EIN the same day they apply online. If you're also waiting on related filings like E-Verify Enrollment, coordinate those timelines separately — they do not delay EIN issuance.
There is no government filing fee to obtain an EIN from the IRS — the application is always free, per the IRS Fee Schedule. However, you may incur costs if you hire a tax professional or accountant to prepare or submit the form on your behalf. Not legal advice — verify with the IRS by calling 1-800-829-4933 or visiting irs.gov.
No — an EIN is permanently assigned to a specific business entity and cannot be transferred or reassigned, per IRS regulations (26 U.S.C. § 6109). If you relocate your restaurant to a new address, you keep the same EIN; you do not need to reapply. However, you must file Form 8822-B with the IRS to notify them of the address change, and you'll likely need to obtain a new City Business License/Registration in your new jurisdiction.
An EIN does not expire and does not require renewal — once issued, it remains valid for the life of your business, per the IRS. You do not need to reapply unless your business structure changes (e.g., you convert from a sole proprietorship to an LLC), in which case you would apply for a new EIN.
There is no inspection process for an EIN application — the IRS reviews your Form SS-4 for completeness and eligibility and either approves or denies it based on documentary evidence. The IRS does not conduct site visits or inspections as part of EIN issuance. However, you should expect IRS audits or verification requests once you begin filing payroll taxes and employment tax returns as an employer.
Yes — you must have an EIN before you can enroll in E-Verify Enrollment or set up EFTPS Enrollment (Electronic Federal Tax Payment System), per IRS and Department of Homeland Security requirements. Apply for your EIN first, then use it to complete your employment and tax compliance filings.
Any restaurant that has employees must have an EIN, per 26 U.S.C. § 6109 and IRS rules. Sole proprietors with no employees may use their Social Security Number instead, but most restaurant owners apply for an EIN to separate personal and business finances. Not legal advice — consult a tax professional to determine if your business structure requires an EIN.
