Apply EIN IRS Form SS4 Online – Applying for an Employer Identification Number (EIN) is a crucial step for starting a business, hiring employees, or managing certain tax obligations in the United States. Also known as a Federal Tax Identification Number, an EIN helps the IRS track your business’s financial activities. The good news is that you can apply for an EIN online using IRS Form SS-4, which is the fastest and most convenient method. This comprehensive guide walks you through the process, eligibility, and tips to ensure a smooth application. Whether you’re a sole proprietor, LLC owner, or corporation executive, we’ll cover everything you need to know based on the latest IRS guidelines.
What Is an EIN and Who Needs One?
An Employer Identification Number (EIN) is a unique nine-digit number assigned by the Internal Revenue Service (IRS) to businesses, organizations, and certain trusts for tax purposes. It’s essentially your business’s Social Security Number, used for filing taxes, opening bank accounts, and complying with federal regulations.
You typically need an EIN if:
- Your business hires employees.
- You operate as a partnership, corporation, or multi-member LLC.
- You’re required to file employment, excise, or alcohol/tobacco/firearms taxes.
- You withhold taxes on income paid to non-resident aliens.
- Your organization involves trusts, estates, or non-profit entities.
- You’re changing your business structure or ownership.
Even sole proprietors without employees may benefit from an EIN for separating personal and business finances. If you’re forming a new legal entity like an LLC or corporation, register it with your state first to avoid application delays.
Eligibility for Online EIN Application
Not everyone can apply for an EIN online—the IRS has specific criteria to ensure security and accuracy. You’re eligible if:
- Your principal business location is in the U.S. or a U.S. territory.
- You’re the “responsible party” (the person who controls the entity’s funds and assets) or an authorized third-party designee.
- You have a valid Social Security Number (SSN), Individual Taxpayer Identification Number (ITIN), or EIN (for government entities only).
Third-party designees must have signed authorization from the responsible party.
However, you cannot apply online if:
- Your business is based outside the U.S. (international applicants must use phone, fax, or mail).
- You’re applying on behalf of an entity without proper authorization.
- You’ve already reached the daily limit (one EIN per responsible party per day).
If ineligible for online filing, explore alternative methods outlined later in this guide.
Required Information and Preparation
Before starting your online EIN application, gather the necessary details to complete Form SS-4 efficiently. The IRS requires:
- Business entity type (e.g., sole proprietorship, LLC, corporation).
- Responsible party’s SSN or ITIN.
- Business name, address, and county/state.
- Reason for applying (e.g., starting a new business, hiring employees).
- Date the business was started or acquired.
- Industry or principal line of business.
- Number of employees (if applicable).
- For third-party designees: Signed authorization form.
Pro tip: Double-check all information for accuracy, as errors can lead to delays or the need for a new application. Also, form your legal entity with your state beforehand if applicable.
Step-by-Step Guide to Applying for an EIN Online
The online EIN application is straightforward and can be completed in minutes via the IRS website. Here’s how:
- Visit the IRS EIN Application Page: Go to the official IRS online EIN assistant tool. It’s available free of charge—avoid third-party sites that may charge fees.
- Select Your Entity Type: Answer questions about your business structure to begin Form SS-4 electronically.
- Provide Responsible Party Details: Enter the SSN or ITIN of the controlling individual. If you’re a third-party, upload or reference your authorization.

- Review and Submit: Double-check all entries. The application must be completed in one session—no saving drafts. Submit during operational hours to receive your EIN immediately upon approval.
- Receive Your EIN: If approved, download and print your confirmation letter with the assigned EIN.
The process typically takes 15-30 minutes, but sessions expire after 15 minutes of inactivity, so stay active.
Limitations and Tips for Success
While online filing is efficient, be aware of these constraints:
- Operational Hours: Monday–Friday: 6 a.m. to 1 a.m. ET (next day); Saturday: 6 a.m. to 9 p.m. ET; Sunday: 6 p.m. to midnight ET.
- Daily Limit: Only one EIN per responsible party per day.
- No International Access: Principal business must be in the U.S.
Tips to avoid issues:
- Apply during off-peak hours to minimize technical glitches.
- Use a secure, stable internet connection.
- Keep a copy of your confirmation for records, as the IRS doesn’t mail it automatically.
- Beware of scams—always use the official IRS.gov site.
What Happens After Applying?
Once you receive your EIN, you can immediately use it for tax filings, banking, and business operations. The IRS issues it on the spot for eligible applications. If there’s an issue, you may need to resubmit or contact the IRS. Update your records and notify relevant parties, like your bank or state agencies. Remember, EINs don’t expire but may need replacement if your business changes significantly.
Alternatives to Online EIN Application
If online isn’t an option, you can apply via:
- Phone: Call the IRS Business and Specialty Tax Line (for international applicants too).
- Fax: Complete Form SS-4 and fax it to the appropriate number.
- Mail: Send the paper Form SS-4 to the IRS service center for your location (processing takes 4-6 weeks).
