  • An Employer Identification Number (EIN) is a unique nine-digit number issued by the United States Internal Revenue Service (IRS) to identify a business for taxation purposes. It is also known as a Federal Employer Identification Number (FEIN) or Federal Tax Identification Number. Similar to how a Social Security Number identifies an individual in the United States, an EIN is used to identify a business in tax returns, payroll records, business banking activities and official communications with the IRS.
    This guide explains what an EIN is, who requires one, how to apply for it through the IRS, how it differs from a Taxpayer Identification Number (TIN), and the equivalent identifiers used in India such as PAN, GSTIN, and TAN, which perform similar business identification and tax-compliance functions under Indian regulations.

    In summary

    An Employer Identification Number is a free, 9-digit tax identification number issued by the IRS to identify businesses for federal tax purposes. Most eligible applicants receive it immediately when applying online, making it quick and convenient to obtain.

    • An EIN is a free 9-digit number issued by the IRS in the format XX-XXXXXXX to identify a business for tax reporting and compliance.
    • FEIN (Federal Employer Identification Number) and Federal Tax Identification Number are alternative names for the same EIN.
    • You can apply online for immediate issuance, by fax in approximately four business days, or by mail in around four weeks.
    • Once issued, an EIN is permanent. It is not reused or cancelled, even if the business closes.
    • The closest Indian equivalents are PAN for income tax, GSTIN for GST compliance, and TAN for TDS/TCS-related transactions.

What is an Employer Identification Number (EIN)?

  • An Employer Identification Number is a unique 9-digit tax identification number, formatted as XX-XXXXXXX, issued by the Internal Revenue Service (IRS) to identify businesses for federal tax purposes. The EIN meaning is similar to a business tax ID. It is also known as a FEIN (Federal Employer Identification Number) or Federal Tax Identification Number.

    An EIN is issued free of cost and remains permanently assigned to the business, even if it stops operating. It is used for tax filing, opening business bank accounts, hiring employees, and other official business activities.

    What is a State Employer Identification Number?

    Even if your business already has an EIN from the central government, you might also need to get a separate one from the state. Many businesses are required to have a State Employer Identification Number (State EIN) for each state where they pay taxes. In some cases, it can also help protect against identity theft, especially for sole proprietors. 

    Since tax rules can differ from one state to another, business owners should check the local rules to see if they need a State EIN and how to apply for it.

    Employer Identification Number example

    An EIN is formatted as XX-XXXXXXX. For instance, an example of an EIN might be 12-3456789. This number helps the IRS track the business's tax obligations and filings. It's unique to each business and once issued, it is never reissued or reused by the IRS, ensuring that each business's financial and tax history is distinctly maintained under this unique identifier.

  • International applicants, including Indian businesses requiring a US Employer Identification Number, can apply by calling the IRS international EIN helpline.

For Indian businesses requiring a US EIN

An Indian business can obtain a US EIN even without a physical presence in the United States. This may be necessary for activities such as selling on US-based marketplaces, opening US payment accounts, or establishing a US business entity. In such cases, the business can apply by submitting Form SS-4 via fax or post, or by contacting the IRS international EIN helpline. The application must identify a responsible party; however, foreign applicants are not required to have a US Social Security Number (SSN) or Individual Taxpayer Identification Number (ITIN) when applying through these methods.

Where do I find my EIN if it is lost?

  • If you lose your EIN, you can usually recover it by checking your IRS records, previous tax filings, or business banking documents. You do not need to apply for a new Employer Identification Number.

    • Check your original IRS EIN Assignment Notice (CP 575).
    • Look for your EIN on previously filed federal business tax returns.
    • Contact the bank where you opened your US business bank account, as it may have your EIN on file.
    • Call the IRS Business and Specialty Tax Line at 1-800-829-4933 to retrieve your EIN after identity verification.

    If you are unable to locate your EIN using these methods, contact the IRS directly for assistance with recovering your existing number.

    Closing your Employee Identification Number

    Closing an EIN involves notifying the IRS to deactivate the business account linked to the EIN. This is typically done after the business has filed its final tax return and paid all owed taxes. The IRS requires a formal letter stating the reason for the closure, such as dissolution or the business ceasing operations, to finalise the process and prevent future tax liabilities.

Indian equivalent of an EIN: PAN, GSTIN, and TAN

  • India does not use Employer Identification Numbers (EINs). Instead, businesses operating in India are identified through different registration and tax identification numbers issued under Indian tax regulations. If you are an Indian business looking for the equivalent of a business tax identification number, the following identifiers are the most relevant:

    IdentifierIssued byPurposeFormat
    PAN (Permanent Account Number)Income Tax DepartmentThe primary tax identifier for a business. It is required for income tax filings, opening bank accounts and carrying out most financial transactions.10-character alphanumeric code (e.g., ABCDE1234F)
    GSTIN (Goods and Services Tax Identification Number)GST authoritiesIdentifies a business registered under GST. It is required for collecting GST, issuing GST-compliant invoices and filing GST returns.15-character alphanumeric code, linked to the state of registration
    TAN (Tax Deduction and Collection Account Number)Income Tax DepartmentRequired for businesses responsible for deducting or collecting tax at source (TDS/TCS).10-character alphanumeric code (e.g., ABCD12345E)

    For most Indian businesses, PAN serves as the closest equivalent to a US EIN, while GSTIN and TAN are used for specific tax compliance requirements under Indian law.

    How to get an EIN: Processing time

    An Employer Identification Number is issued immediately for eligible online applications, while other application methods can take up to four weeks. If you are wondering how to get an EIN, the processing time depends on the method you choose.

Overview

What is the EIN number in India?

In India, the equivalent of an Employer Identification Number (EIN) is known as the Tax Deduction and Collection Account Number (TAN). This unique identifier is used primarily for businesses managing the deduction and collection of taxes. It is mandatory for entities required to withhold taxes on payments made to third parties, such as employees.

How long will it take to get an EIN?

Obtaining a TAN in India typically takes about 5 to 10 working days from the date of application. This duration can vary depending on the processing speed of the Tax Department and the accuracy of the information provided in the application.

How do i find my Employer Identification Number?

To find a TAN or EIN, businesses can check official correspondence from the tax authorities, or look it up online through government portals like the Income Tax Department’s official website.

What happens if you lose or misplace your EIN?

If you lose or misplace your TAN or EIN, it’s important to contact the issuing authority immediately to secure your tax records and prevent misuse.

How does an EIN support payroll tax compliance?

Businesses use their EIN when submitting Form 941 (Employer's Quarterly Federal Tax Return), reporting federal income tax withholding, and paying Social Security and Medicare taxes. Without an EIN, employers cannot meet many of their federal payroll tax reporting obligations.
