Fact-checked by the LegalGlass editorial team against primary sources · Published Aug 6, 2026 · Last updated Aug 6, 2026

To get an Employer Identification Number (EIN) for an Arkansas business, apply online directly with the Internal Revenue Service (IRS) using Form SS-4. The EIN is free and typically issued instantly upon successful completion of the online application. Most Arkansas LLCs, corporations, and partnerships require an EIN for federal and state tax filings, as well as for opening business bank accounts.

What is an EIN?

An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is a unique nine-digit number assigned by the IRS to identify businesses for tax purposes. It functions similarly to a Social Security Number (SSN) for individuals. An EIN is essential for most Arkansas businesses to comply with federal tax laws, open business bank accounts, and fulfill various other legal and financial obligations. For a general overview, see what is an EIN.

The IRS uses the EIN to track business tax filings, including income tax, employment taxes, and excise taxes. State agencies, such as the Arkansas Department of Finance and Administration (DFA), also use the federal EIN to identify businesses for state tax purposes, including corporate income tax, sales tax, and withholding tax.

Who Needs an EIN in Arkansas?

Most types of businesses operating in Arkansas will need an EIN. The IRS requires an EIN if a business:

• Has employees.
• Is structured as a corporation or partnership.
• Files employment tax returns, excise tax returns, or alcohol, tobacco, and firearms tax returns.
• Withholds taxes on income, other than wages, paid to a non-resident alien.
• Is involved with certain types of organizations, such as trusts, estates, or non-profit organizations.

Specifically for Arkansas businesses:

• Limited Liability Companies (LLCs): If an Arkansas LLC has more than one member, it is generally taxed as a partnership by default and requires an EIN. A single-member LLC, by default, is a disregarded entity and is taxed as a sole proprietorship. It generally does not need an EIN unless it has employees or elects to be taxed as a corporation or S-corporation. However, many banks require an EIN for any LLC to open a business bank account, regardless of its tax classification. For more on LLCs, see how to form an LLC in Arkansas.
• Corporations: All Arkansas corporations, including S-corporations, must obtain an EIN. This includes both C-corporations and those electing S-corporation status.
• Partnerships: All Arkansas partnerships, including general partnerships, limited partnerships (LPs), and limited liability partnerships (LLPs), require an EIN.
• Sole Proprietorships: A sole proprietorship typically uses the owner's SSN for tax purposes. However, an EIN is required if the sole proprietorship hires employees or files excise tax returns. Many sole proprietors also choose to obtain an EIN to keep business and personal finances separate or for banking purposes.

Even if not strictly required by the IRS, obtaining an EIN is often beneficial for any Arkansas business. It helps establish business credit, simplifies tax filings, and is almost always a prerequisite for opening a dedicated business bank account.

How to Apply for an EIN in Arkansas

The process for obtaining an EIN is the same for businesses in Arkansas as it is for businesses in any other U.S. state. The application is handled directly by the IRS. There are four methods to apply:

1. Online (Recommended): This is the fastest method. The IRS online application is available from Monday to Friday, 7 a.m. to 10 p.m. Eastern Time. The EIN is typically issued immediately upon successful completion of the application. The applicant must have a valid Taxpayer Identification Number (SSN, ITIN, or another EIN) to use the online application.
2. Fax: You can fax a completed Form SS-4, Application for Employer Identification Number, to the IRS. Processing times for faxed applications are generally a few business days, and the EIN will be faxed back to you.
3. Mail: You can mail a completed Form SS-4 to the IRS. This is the slowest method, with processing times typically several weeks.
4. Telephone (International Applicants Only): International applicants who do not have a U.S. Taxpayer Identification Number can apply for an EIN by calling the IRS.

Regardless of the method chosen, the application for an EIN is always free when submitted directly to the IRS. Businesses should be wary of third-party services that charge a fee to obtain an EIN, as this is a service the IRS provides for free.

Online Application Steps

To apply for an EIN online for your Arkansas business, follow these steps:

1. Access the IRS Website: Go to the official IRS website and navigate to the online EIN application page.
2. Identify the Responsible Party: The "responsible party" is the individual or entity that ultimately owns or controls the entity and has a level of control over the funds or assets of the entity. This person must have a valid SSN, ITIN, or another EIN. For an LLC, this is typically a member or manager. For a corporation, it's usually an officer.
3. Select Business Type: Choose the legal structure of your Arkansas business (e.g., LLC, corporation, partnership, sole proprietorship).
4. Provide Business Information: Enter the legal name of your business, its mailing address, the county in Arkansas where it is located, and the reason for applying for the EIN (e.g., "Started a new business," "Hired employees").
5. Provide Responsible Party Information: Enter the name and Taxpayer Identification Number (SSN or ITIN) of the responsible party.
6. Review and Submit: Carefully review all the information for accuracy. Errors can cause delays or issues later. Once confirmed, submit the application.
7. Receive EIN: If the application is successful, the EIN will be displayed on the screen immediately. You should save or print this confirmation for your records.

The online application system has certain limitations. For example, only one EIN can be requested per responsible party per day. If you encounter issues, the IRS provides guidance on its website.

Arkansas State Tax Obligations

Once your Arkansas business has an EIN, it will use this number for various state tax registrations and filings with the Arkansas Department of Finance and Administration (DFA). Key state taxes that may apply include:

• Corporate Income Tax: Corporations doing business in Arkansas are subject to corporate income tax. The tax rate is progressive, ranging from 1% to 5.3% on net taxable income for 2026. The EIN is used to register for and file these taxes. More information is available on the DFA Corporate Income Tax page.
• Sales and Use Tax: Businesses that sell tangible personal property or provide taxable services in Arkansas must collect and remit sales tax. The statewide sales tax rate is 6.5% as of 2026, with additional local sales taxes varying by city and county. Businesses must register with the DFA to obtain a sales tax permit. The EIN is required for this registration. See the DFA Sales and Use Tax page.
• Withholding Tax: If your Arkansas business has employees, it must withhold state income tax from their wages and remit it to the DFA. The EIN is used for registration and reporting of state withholding taxes.
• Gross Receipts Tax: Arkansas imposes a gross receipts tax on certain services. Businesses providing these services will use their EIN for registration and reporting. Refer to the DFA Gross Receipts Tax page for details.

It is important for Arkansas businesses to understand their specific state tax obligations and register with the DFA using their new EIN as required. Failure to comply can result in penalties and interest. For a broader view of business tax, see business tax.

Common EIN Issues and Solutions

While obtaining an EIN is generally straightforward, some common issues can arise:

• Duplicate EIN: If you already have an EIN for your business, you should continue to use it. Do not apply for a new one unless there has been a significant change in business structure (e.g., a sole proprietorship incorporates). The IRS generally assigns only one EIN per entity.
• Lost EIN: If you lose or forget your EIN, you can find it on previous tax returns, IRS notices, or by contacting the IRS directly. The IRS does not provide EINs via email or fax for security reasons.
• Incorrect Information: If you made an error on your EIN application, you may need to send a letter to the IRS to correct the information. The specific procedure depends on the type of error.
• Responsible Party Change: If the responsible party for your business changes, you generally do not need a new EIN. However, you may need to inform the IRS of the change.

For detailed guidance on these and other EIN-related issues, consult the IRS website or contact the IRS directly. For general EIN information, see how to get an EIN.
