How To Find A Business Tax ID Number?

Finding a business tax ID number, commonly known as an Employer Identification Number (EIN), is essential for various business operations, including tax filings, opening bank accounts, and applying for loans. If you’ve misplaced your EIN or need to locate it for another business, there are several reliable methods to do so. This article will help you with some practical and reliable ways to identify your EIN for your business. 

What is a business tax ID number? Employee Identification Number (EIN)

A Business Tax ID Number, commonly referred to as an Employer Identification Number (EIN), is a unique nine-digit number assigned by the IRS to identify a business entity for tax purposes. Much like a Social Security Number (SSN) for individuals, the EIN is used by businesses to file taxes, open business bank accounts, apply for business licenses, and manage payroll. It’s required for any business with employees, operating as a corporation or partnership, or those that file specific tax returns such as excise taxes.

An EIN is essential for separating personal and business finances, ensuring compliance with tax regulations, and facilitating smoother business transactions. Whether you’re a sole proprietor considering hiring your first employee or an established corporation, obtaining an EIN is a critical step in maintaining your business’s legal and financial integrity.

Why you need a business tax ID number

A Business Tax ID Number, or EIN, is essential for identifying your business to the IRS, opening bank accounts, hiring employees, and filing taxes. It separates personal and business finances, protecting your personal assets and reducing identity theft risks. Required for corporations, partnerships, and LLCs, an EIN is also useful for sole proprietors looking to streamline financial management. Having an EIN legitimizes your business and ensures compliance with legal and financial requirements. 

How to find your EIN?

There are several reliable ways to find your business’ EIN. We will share a few reliable methods so that you can always check for your EIN.

Check your EIN confirmation letter 

To find your EIN, check key documents like your IRS confirmation notice (CP 575), past tax returns, or any official correspondence from the IRS. After you have successfully filed for your business’ incorporation with the IRS, you would have received a confirmation letter acknowledging your business’ status. This is where you will find your business EIN. 

Review business documents

If you are not able to find your EIN confirmation letter, your EIN may also appear on financial statements, business licenses, or loan applications. Additionally, it might be recorded on any previously filed tax returns or payroll documentation, as these typically require your EIN for submission. Checking with your bank or financial institution where you opened a business account can also be a good option, as they usually keep a record of your EIN.

Call the IRS

If you still can’t locate your EIN, contacting the IRS directly through their Business & Specialty Tax Line is a reliable option. Ensure that only authorized individuals, such as business owners or partners, make the call, as the IRS requires proper identification to release the EIN. It’s crucial to keep your EIN stored securely yet easily accessible to prevent any disruptions in business operations, such as delays in tax filings or financial transactions. This proactive approach helps maintain smooth business management and compliance with tax obligations

Online search 

To search for an EIN online, you can utilize various resources depending on your needs. 

• For publicly traded companies, the SEC’s EDGAR database is a free tool where you can find EINs within filed documents. Through EDGAR, you can find an EIN by searching for company filings, such as annual reports (Form 10-K) or registration statements. This database is particularly useful for verifying EINs of publicly traded businesses, ensuring that you’re accessing accurate and up-to-date information. EDGAR’s user-friendly search options allow you to look up companies by name, Central Index Key (CIK), or other criteria.

• For non-profits, websites like GuideStar offer detailed EIN information. Additionally, commercial services like FEINSearch or EIN Finder provide EIN lookup options for a fee, allowing you to search for EINs of businesses across the U.S. These tools can be useful when you need to verify a business’s EIN or access other public business records

Get help with your search 

If you’re struggling to find an EIN or need assistance with your search, several options are available to help. Start by consulting any official IRS documents or previous tax returns. If these resources don’t yield results, consider contacting the IRS directly or using online tools like the SEC’s EDGAR database for publicly traded companies. For more complex searches, commercial services offer EIN lookup options for a fee. Additionally, seeking help from a tax professional can ensure you navigate the process efficiently and accurately.

How to get an EIN (business tax ID number)

Obtaining an EIN (Employer Identification Number), also known as a Business Tax ID Number, is a straightforward process. You can apply for an EIN directly through the IRS website using the EIN Assistant, which is available online and provides immediate issuance of your EIN. 

Alternatively, you can apply by mail or fax by submitting Form SS-4 to the IRS. The application will require basic information about your business, such as its legal name, address, and the type of entity. For those who prefer phone applications, the IRS also offers this service for international applicants. Once you have your EIN, it’s crucial to store it securely, as it will be required for tax filings, opening bank accounts, and other official business operations

How to cancel or change an EIN

Once an EIN (Employer Identification Number) is assigned to a business, it generally cannot be canceled or changed, as it remains permanently tied to the entity. However, if your business no longer needs an EIN—perhaps due to closure or restructuring—you can close your IRS business account by sending a letter to the IRS that includes the full legal name of your business, the EIN, and the reason for closing the account. 

While the EIN won’t be reused, it won’t be considered active anymore. If your business undergoes significant changes, such as a change in ownership or legal structure, you may need to apply for a new EIN rather than altering the existing one. Always consult with the IRS or a tax professional to ensure compliance during such transitions
