Why You Need a Application for Employer Identification Number
The requirement for an Employer Identification Number (EIN) is a federal mandate established under the Internal Revenue Code (Title 26). Every business entity that has employees, operates as a corporation or partnership, or files certain tax returns must obtain this unique nine-digit number from the Internal Revenue Service. This is a prerequisite for opening business bank accounts, applying for Portland-specific business licenses, and handling payroll with the Oregon Department of Revenue. While Portland or Multnomah County may not issue the EIN, they require it as a foundational identifier for all subsequent local permits and tax registrations.
Operating without an EIN when required carries significant financial and operational penalties enforced by the IRS and can block your ability to open doors in Portland. Consequences include:
- Failure-to-file penalties: 5% per month (up to 25%) of the unpaid tax shown on the return.
- Failure-to-pay penalties: 0.5% per month on taxes not paid by the due date.
- Accrued interest on all unpaid amounts.
- Inability to open a dedicated business bank account or secure business credit, which most commercial leases in Portland require.
- Risk of criminal prosecution for tax evasion or fraud if you willfully operate without an EIN to avoid tax obligations.
Legal code: Internal Revenue Code (Title 26)
Recent update: The IRS continues to promote and accept online EIN applications via its website, which remains the fastest processing method; there have been no major changes to the core application form or fee structure in 2026.

74 of 89 auto-filledMailing address - City, State, ZIP
textEnter the city, state abbreviation, and ZIP code for the location where you want to receive IRS correspondence, which must match the street address entered in the previous line of the form.
COMMON MISTAKE: Entering a P.O. Box or private mailbox (PMB) number here; these should be listed on the "Street address" line, not in this field.
Physical address - City, State, ZIP
textEnter the city, state, and ZIP code for your restaurant's principal physical location, which may be used by the IRS for verification if your mailing address is a P.O. Box.
COMMON MISTAKE: Leaving this blank or repeating the mailing address if the restaurant's physical location is different, which can delay processing.
Sole proprietor - SSN
textIf you are a sole proprietor filing as an individual, enter your valid Social Security Number (SSN) in the format XXX-XX-XXXX.
COMMON MISTAKE: Entering an Employer Identification Number (EIN) here instead of an SSN, or formatting the SSN without hyphens.
State of incorporation
textEnter the two-letter abbreviation for the U.S. state where your corporation was legally formed, such as 'OR' for Oregon.
COMMON MISTAKE: Entering the state where the restaurant physically operates instead of the state where the entity was incorporated, which is a legal mismatch.
Is this an LLC? - Yes
checkboxCheck this box only if your business is legally structured as a Limited Liability Company (LLC).
COMMON MISTAKE: Checking 'Yes' for LLC when the entity is actually a sole proprietorship or corporation, which directs you to incorrect follow-up questions.
Is this an LLC? - No
checkboxCheck this box if your business is any structure other than a Limited Liability Company (LLC), such as a sole proprietorship, partnership, or corporation.
COMMON MISTAKE: Leaving both 'Yes' and 'No' boxes unchecked, which will cause the IRS to reject the form as incomplete.
LLC organized in US? - Yes
checkboxIf you answered 'Yes' to being an LLC, check this box only if the LLC was formed under the laws of any U.S. state or the District of Columbia.
COMMON MISTAKE: Checking 'Yes' for an LLC organized in a U.S. territory or possession, which should be marked 'No'.
LLC organized in US? - No
checkboxIf you answered 'Yes' to being an LLC, check this box only if the LLC was formed under the laws of a foreign country.
COMMON MISTAKE: Checking 'No' for a domestic LLC, which requires you to provide additional foreign entity information and can delay processing.
Entity type: Other
checkboxCheck this box only if your legal structure is not listed among the other specific options (e.g., a trust, estate, or REMIC).
COMMON MISTAKE: Selecting 'Other' for a common entity type like a corporation or partnership, which requires you to specify the entity type in writing and adds processing time.
Entity type: Other nonprofit organization
checkboxCheck this box if your organization is a nonprofit that does not have a 501(c)(3) determination letter from the IRS, such as a social welfare organization under 501(c)(4).
COMMON MISTAKE: Selecting this for a standard 501(c)(3) charity, which has its own dedicated checkbox; this error can affect your tax-exempt status application.

Top 5 Application for Employer Identification Number Mistakes
1. Submitting as an Individual Instead of a Business Entity
Entering your personal Social Security Number (SSN) as the 'Responsible Party' when applying for a business entity like an LLC or corporation. The IRS will reject the application because the EIN is a business tax ID. Instead, the 'Responsible Party' must be the individual who ultimately owns or controls the entity (e.g., managing member of an LLC, president of a corporation). Using a personal SSN for a business EIN adds 3–4 weeks for a correction and can cause payroll and bank account setup delays.
2. Selecting the Wrong 'Reason for Applying'
Choosing an incorrect or vague reason on line 9 of Form SS-4, such as 'Starting a new business' when the specific reason is 'Started a new LLC.' The IRS uses this to categorize your tax obligations. For a new Portland restaurant, the correct selection is typically 'Started a new business' and you must check the box for 'LLC' below it. An incorrect reason can lead to misclassification and future IRS notices, requiring follow-up correspondence to fix.
3. Mismatched Legal Name and Business Address
Providing a 'Doing Business As' (DBA) name or a future planned name in the 'Legal Name' field, or using a home address instead of the restaurant's principal physical address in Portland. The EIN application requires the legal name of the entity as registered with the Oregon Secretary of State and the true physical street address (not a P.O. Box). For example, if your LLC is 'Rose City Eats LLC' operating as 'The Pioneer Grill,' you must use the LLC name. A mismatch is a common cause of rejection and can invalidate the EIN for licensing purposes.

Timeline: From Application to IRS Issuance
Gather Required Information
Collect the legal name, social security number (SSN) or Individual Taxpayer Identification Number (ITIN) of the responsible party (like the owner), and the restaurant's legal structure and mailing address. You'll also need the opening date of your business and an estimate of the highest number of employees expected in the next 12 months. For LLCs or corporations, have your articles of incorporation or organization documents on hand. The most common delay is mismatched names between the owner's SSN and the business entity filing.
Complete and Submit IRS Form SS-4
Fill out the 1-page, 18-field IRS Form SS-4, "Application for Employer Identification Number." The quickest method is the online application on IRS.gov, which provides an EIN immediately upon submission. You can also apply by fax or mail. ApronPrep auto-fills 12 of the 18 fields from your business profile. Ensure the business's legal name matches exactly what is filed with the Oregon Secretary of State if you are incorporated. Incorrect entity type selection is a leading cause of IRS rejection, which requires restarting the process.
IRS Review and Immediate Processing (Online)
For online applications, the IRS system validates your information in real-time. If all data is correct and matches their records (particularly the responsible party's SSN/ITIN and name), the EIN is issued instantly. This automated review checks for duplicate applications and valid entity structures. Have your confirmation details ready to save or print your IRS EIN Assignment Letter (CP 575) immediately. If the system flags an inconsistency, you'll receive an error and must correct it before resubmitting.

See All RequirementsProcessing time varies significantly, as the IRS handles federal EIN applications. While many applicants receive their number immediately upon completing the online application, mailed Form SS-4 submissions can take 4-6 weeks. For a restaurant owner, securing a federal EIN is often a prerequisite for the City Business License/Registration. Contact the IRS for the most current processing timelines.
There is no government filing fee to apply for an Employer Identification Number from the IRS. This is a federal requirement issued at no cost to help track your business's tax identity. Not legal advice — verify with the Internal Revenue Service.
No. An EIN is permanently assigned to your business entity. If you move your restaurant to a new address but the legal entity (e.g., your LLC) remains the same, you simply update your address with the IRS, the state, and local agencies like Portland's Bureau of Revenue and Financial Services. A new EIN is generally only required if you change the business's legal structure, such as incorporating a sole proprietorship. You will also need to update your address for your Certificate of Occupancy.
An Employer Identification Number (EIN) does not expire or require renewal. It is a permanent federal taxpayer identification for your business. However, you must keep your associated business information (like address and responsible party) current with the IRS. This contrasts with local permits that require annual renewal, so contact the issuing authority to confirm requirements.
There is no physical inspection for an EIN. It is a purely administrative process for tax identification. The 'inspection' phase is the IRS's internal validation of your application data against its records. If your information matches and the application is complete, your EIN is issued. Restaurant inspections are related to operational permits, not federal tax IDs.
