Every restaurant business, from a sole proprietorship to a corporation, is legally required to obtain an Employer Identification Number (EIN) from the U.S. Internal Revenue Service under the Internal Revenue Code (Title 26). It is the federal tax ID used to identify your business entity for federal, state, and local tax administration. In Tacoma, Washington, you cannot legally open a business bank account, apply for your state and city business licenses, or hire employees without first securing this number. The EIN application is a foundational federal filing that is mandated regardless of your location; it is not a substitute for local licenses like a Tacoma Business License or Washington State Food Worker Permit, but a prerequisite for obtaining them.
Attempting to operate your Tacoma restaurant without an EIN or using a Social Security number for business purposes creates significant legal and financial risks. Common consequences include:
Legal code: Internal Revenue Code (Title 26)
Recent update: As of 2026, the IRS has fully implemented its electronic filing mandate for EIN applications (Form SS-4), eliminating the previous fax-only option for most applicants and streamlining the online issuance process.

|---|---|---|
| Restaurant (Full-Service) | Required | Required for any business with employees, a business bank account, or which must file business tax returns with the IRS. |

| Food Truck | Required | Necessary to hire drivers or other employees, set up payroll, and comply with state business tax filings. |
| Coffee Shop / Café | Required | Required to hire baristas or staff, which triggers the IRS requirement to have an EIN for payroll tax purposes. |

See Full Requirements →Enter the city, state, and ZIP code for the mailing address where the IRS will send official correspondence and your EIN acceptance letter.
COMMON MISTAKE: Using a P.O. Box without the correct ZIP+4 or listing the owner's personal address when a commercial address is the official mailing point, which can delay IRS mail delivery.
Enter the city, state, and ZIP code for the physical location of your restaurant's principal place of business.
COMMON MISTAKE: Leaving this blank for a home-based business or entering a location different from the state where you are applying for permits, which triggers IRS review for potential out-of-state nexus issues.
If you are a sole proprietor with no employees (other than yourself), enter your valid Social Security Number (SSN) in the format XXX-XX-XXXX.
COMMON MISTAKE: Sole proprietors incorrectly entering an ITIN or leaving this blank while checking the 'Sole Proprietor' box, which is a primary reason for application rejection by the IRS.
For corporations (C-Corp or S-Corp), enter the two-letter abbreviation for the state where the business is legally incorporated (e.g., 'WA' for Washington).
COMMON MISTAKE: Entering the state where the restaurant operates instead of the state where the Articles of Incorporation were filed, which causes a mismatch with state Secretary of State records and leads to processing delays.
Check this box only if your business is legally structured as a Limited Liability Company (LLC).
COMMON MISTAKE: LLC owners checking 'Yes' but then failing to correctly complete the subsequent LLC-specific fields (like organization location), creating an inconsistent entity profile.
Check this box if your business is any structure other than an LLC, such as a sole proprietorship, partnership, or corporation.
COMMON MISTAKE: Single-member LLCs mistakenly checking 'No' because they view themselves as a sole proprietor, which misclassifies the entity for tax purposes.
If you checked 'Yes' for LLC, check this box if your LLC was formed in any U.S. state or territory.
COMMON MISTAKE: Checking 'Yes' for a foreign-formed LLC (e.g., organized in Canada but operating in Washington), which requires a separate application process and will be rejected.
Check this box only if your LLC was legally formed outside the United States or its territories.
COMMON MISTAKE: Domestic LLCs accidentally checking 'No,' which flags the application for international entity review and requires submission of Form SS-4 with a physical signature, adding weeks to processing.
Check this box only if your business structure is not listed in the other categories (e.g., a trust, estate, or REMIC).
COMMON MISTAKE: Restaurant owners incorrectly selecting 'Other' for common structures like LLCs taxed as partnerships, which then requires a detailed written explanation on Line 9b and often triggers a manual review.
Check this box if your restaurant is operated by a nonprofit organization that is not a church, school, or 501(c)(3).
COMMON MISTAKE: For-profit social enterprises checking this box without having an IRS determination letter proving nonprofit status, which is a definitive reason for EIN rejection and potential audit flags.

Entering your personal 'doing business as' (DBA) name on Line 1 when you've formed an LLC or corporation, or listing the business structure incorrectly in Section 8. The IRS systems cross-check your application against state business registrations. If the legal name or entity type doesn't match your Washington Secretary of State filing, your EIN application will be rejected, forcing you to reapply. Avoid this by using the exact legal name from your Articles of Organization/Incorporation and selecting the correct entity type (e.g., 'Limited Liability Company (LLC)' for a Washington LLC).
Listing someone who does not have control over the entity's funds or decision-making, like an employee or contractor, as the responsible party (Section 7a). For most small businesses, this must be an individual—a member for an LLC or a principal officer for a corporation. The IRS verifies this party's Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN). An incorrect or mismatched responsible party will cause an immediate rejection. To avoid this, ensure the person listed is the true controlling owner or officer and that their SSN/ITIN and legal name are entered exactly as they appear on their tax returns.
Using a P.O. Box in the physical location field (Line 3) or providing an address where the business does not have a legitimate physical presence. The IRS requires a street address for the principal business location. Similarly, using a home address for the business when your state filing lists a registered agent's address can create discrepancies. While not always a rejection, it can delay processing and cause mail issues. Always use the actual street address of your Tacoma business or, if home-based, your home address. The mailing address (Line 4) can be a P.O. Box.

Confirm you are applying as a legal business entity (e.g., LLC, corporation, partnership) or for a sole proprietorship with employees/retirement plans. You will need the legal name of the responsible party (owner, officer, etc.), their Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN), and the exact legal name and physical address of your restaurant. Misreporting the 'responsible party' or entity type is a common reason for application issues.
Use the IRS's online EIN Assistant application portal on IRS.gov. You must complete the session in one sitting and cannot save progress. The form has 26 primary data fields, covering entity details, reason for applying, and responsible party information. For a Tacoma restaurant, you will need to select the correct NAICS code (e.g., 722511 for full-service restaurants). The online application is the only method that provides an immediate EIN.
Upon successful online submission, you will receive your 9-digit EIN immediately on the confirmation screen. Download, print, or save the PDF of the official IRS confirmation letter (Form 147C). This is your proof of assignment. The IRS does not charge a government filing fee for obtaining an EIN.
This is one of 13 requirements for opening a restaurant in Washington.

See All RequirementsThe processing timeline for an EIN application varies. According to the IRS, once you submit the completed Form SS-4, immediate online issuance is typical, but paper-filed applications can take several weeks. Contact the IRS directly to confirm current processing times, as delays can hold up your business formation and subsequent local requirements like a City Business License/Registration.
There are no government filing fees ($0) charged by the IRS to obtain an Employer Identification Number. This applies nationally. However, this is a prerequisite for paid local and state filings, such as the Annual Report Filing with the Washington Secretary of State.
An Employer Identification Number (EIN) is tied to your business entity, not its location. If you move your business within Tacoma, you should update your address with the IRS but you keep the same EIN. You will, however, need to update your address on all related permits and licenses, including your City Business License/Registration.
An EIN does not expire and does not require renewal. It is a permanent federal tax ID for your business. However, you must keep your business information updated with the IRS, and you will have ongoing filing obligations that use the EIN, such as state-level Annual Report Filing and federal tax returns.
There is no inspection associated with obtaining an Employer Identification Number. The EIN is a tax identification number issued by the IRS based on your application. Local inspections, like those for a Building Permit or health permit, are separate processes managed by Tacoma city departments.
