Wondering what is a tax ID number?

Well, it’s just like the social security number, but for businesses.

Every person born in the United States is assigned a Social Security Number (SSN) at birth.

This number is used by the Social Security Administration (SSA) and the Internal Revenue Service (IRS) to track income and determine the social security benefits of each person with an SSN.

This number follows you for your entire lifetime and must be disclosed in certain instances, such as applying for a federal loan, opening a bank account, and filing taxes.

Similarly, when a new business is formed, it also requires an identifying number for business tax and operation purposes. This number,  known as a Tax ID, is assigned by the IRS.

The ABCs of Tax IDs

Perhaps you’ve heard of a Tax ID Number by a different name. Employer Identification Number (EIN), Federal Employer Identification Number (FEIN) and Federal Tax ID Number (Federal TIN) all refer to the same nine-digit number — with the format 12-3456789 — provided by the IRS to new businesses.

A federal Tax ID is necessary when applying for a business license, opening a business bank account and/or establishing a line of credit, hiring employees, filing tax reports/returns/payments, and more.

Taxpayer Identification Number (TIN) vs. Employer Identification Number (EIN)

A TIN (Tax Identification Number) is a broad term that describes any form of identification number for a taxpayer. An Employer Identification Number (EIN) is a special type of TIN that identifies a business for tax reporting purposes.

These terms are often used interchangeably, and when someone requests to see the tax ID for your business, they are simply referring to your EIN.

Besides EIN, TIN is a generic descriptor for other tax IDs used on a tax form, including but not limited to:

      • SSN (Social Security Number)
      • ITIN (Individual Tax Identification Number)
      • ATIN (Adoption Tax Identification Number)
      • PTIN (Preparer Tax Identification Number)

FEIN vs. EIN

FEIN stands for Federal Employer Identification Number. It’s similar to the EIN, only that it’s offered by the federal government and not the state.

FEIN also gives users access to the digital federal tax system where they can easily make their tax payments online or over the phone.

Do you need a Tax ID?

Not every new business needs a Tax ID. For example, a single business owner can choose to conduct business or provide services as an individual, in which case taxes are associated with his or her SSN instead of an EIN.

However, you will need to apply for a Tax ID if any of the following are true:

      • You need to open a business bank account or want to start a business line of credit
      • You have hired or will hire employees, including household employees
      • You have formed or created a Trust, pension plan, Corporation or Partnership
      • You have formed an LLC with employees or a Sole Proprietorship with excise tax return or pension filing needs
      • You wish to obtain a business license or building permits, pay state or local taxes, or issue 1099 forms to independent contractors
      • You changed the legal character or ownership of your organization (i.e., you incorporate a Sole Proprietorship or form a Partnership)
      • You are representing an estate that operates a business after the owner’s death
      • Your business has a Keogh plan (a tax-deferred pension plan available to self-employed individuals or unincorporated businesses for retirement purposes)

Even if you can use your SSN in place of an EIN, you may not want to. When clients are asked to pay an invoice, they will need information from you — including an SSN — to make payments.

Sending such sensitive information to clients may increase your chances of identity theft. For the sake of privacy, creating a Tax ID for your business may be beneficial in the long run.

Additionally, to create a business bank account, you will need a Tax ID/EIN. Having a business bank account is ideal to separate your business and personal finances, income, and expenses.

Documentation is very important for all businesses, and having an EIN and a bank account helps to organize, document and operate in compliance with tax and government regulations.

Which Business Entities Need EIN?

Certain businesses are required to have an EIN by the IRS as part of their reporting and operating requirements. Without this crucial ID, the business cannot operate legally in the state and could face heavy fines for non-compliance.

But before starting an application, you need to understand if you need an EIN or not. Remember, not all businesses are required to get an employer identifier number. But even if you’re not required to have an EIN, you may want to get one.

Let’s go through the details of what is a tax ID to see which entities need an EIN.

Independent Contractors and Freelancers

Independent contractors and freelancers don’t need an EIN. They can simply report their earnings and file taxes with their SSN.

Sole Proprietorship

If your business is set up as a sole proprietorship and you don’t have any employees, then you don’t need an Employer Identifier Number.

But if your Sole Proprietorship has employees, then you’re required to know what is a tax ID and obtain an EIN for your business.

Besides allowing you to hire employees, an EIN allows you to open a business bank account so you can separate your personal and business funds.

This makes it easy to build business credit and obtain a loan to grow your business. Additionally, EIN reduces the risk of identity theft since you will not be sharing your SSN with your business clients.

Single-member LLC

If your business is structured as a single-member LLC and you don’t have any employees, then you’re not required to get an Employer Identification Number.

However, single-member LLCs with employees are required to have an EIN for tax reporting purposes.

They also need the employer identifier number to hire employees and open a bank account. This helps the organization maintain its corporate veil and build business credibility.

Partnerships or Multi-member LLC

Businesses established as a partnership or multi-member LLC must get an EIN because the business must file a partnership return and provide the members of the LLC with their K-1s.

Corporations

If your business has an S-Corporation tax structure, you’re required to obtain an EIN so you can pay taxes.

C-Corps are also viewed as a separate business entity from the owner and need an Employer Identification Number for reporting their taxes.

Nonprofit Organizations

Nonprofit organizations need an Employer ID to report their taxes.

Trusts

Trusts need an employer ID when classified as irrevocable. An irrevocable trust is a separate legal entity that cannot be changed by the grantor. As such, the trust needs its own tax ID, which is the EIN.

    • Open a bank account Banks require individuals to produce an EIN when opening a business bank account. Besides the EIN, you may also have to show your incorporation documents or “Doing Business As” certificate to prove your business has been registered formally.
    • Apply for a business license in your state – Many states require business owners to know what a tax ID number is and produce their EIN to get a license that permits them to conduct business in the state.
    • File a tax return by mail – You need an EIN to file your federal income tax return by mail. Bear in mind that it may take the IRS up to eight weeks to process your tax return when you use this option.
    • Take a business loan – Most banks require business owners to have a business account to apply for a loan. And as we have already established, you need an EIN to open a business bank account.
    • Hire employees – You cannot hire employees for your business without EIN. You also need an EIN to set up your payroll system.
    • Boost credibility – Tax ID sets you apart as a serious and responsible individual whos committed to the business.

It’s important to note that it can take up to two weeks for your Tax ID to become recognized by official IRS records. You may have to wait until you can use your EIN to file an electronic tax return, make an e-payment or pass an IRS Taxpayer Identification Number (TIN) matching program. Please also note that different banks have different requirements and some may request the official letter from the IRS, which is sent to the address provided in the online Tax ID application. This can take up to four weeks to arrive.

Once you have your federal Tax ID, you will need to look into state government requirements. Every state is different, so you will need to determine the filing requirements for your state. You may need to get a State Tax ID number if you are selling tangible goods. If you are creating an LLC or a Corporation, it is required to file your Articles of Organization (for LLCs) or Articles of Incorporation with your state.

Important Things to Know When Applying for EIN

There are a few things you need to note when applying for an EIN. They include:

Responsible Party

Besides knowing what a tax ID is, the IRS requires EIN applicants to state the name and provide the tax identification number (TIN) of the officer, general partner, owner, trustor, or true principal of the business.

This individual is known as the responsible party and he or she is responsible for the management and control of the applicant entity. The responsible party is also in charge of the funds and assets of the company applying for the tax ID.

The IRS requires that the responsible party be a natural person. It cannot be a government entity or another business entity.

Third Party Authorization

When applying for an EIN, applicants need to complete the third party authorization section. For the third party authorization to be valid, the taxpayer should sign the form as well.

After completing and signing the form, the taxpayer should fax or mail the form to an IRS service center. The third party authorization only applies to newly assigned EINs. The authority ends when the EIN is released.

Tax Exemption Status

Before applying for your EIN, ensure your company is registered legally. The IRS assumes that all organizations applying for tax ID know what is a tax ID and are legally formed.

You should also note that all organizations that are exempt from federal income tax under IRS 501(a) get their tax exemption status withdrawn if their annual tax returns are not filled for three years.

If this applies to your organization, take note that the countdown to this 3-year period starts when you apply for your tax ID.

Limitation on Issuance of EIN

The IRS now limits the issuance of EIN to one ID per one responsible party per day. The limitation applies irrespective of the method used to apply for the EIN (online, mail, fax, or telephone).

According to the IRS, this limitation is in place to bring fairness to the entire process.

How Long Does it Take to Receive Your EIN?

The amount of time it takes to receive your EIN depends on the method of application used. The processing time for each of these methods is different as you will see below.

Applying for EIN Online

When you apply for your EIN online, the ID is issued almost immediately.

Applying for EIN by Fax

EIN applications by fax are processed in approximately four business days.

Applying for EIN by Mail

When you apply for your EIN by mail, your ID will be processed in approximately four weeks.

Applying for EIN by Telephone

Applying by phone is easy and your tax ID could be issued almost immediately if everything progresses smoothly. The IRS agent who handles your EIN application may ask you to fax or mail your form SS-4 not more than 24 hours after the phone call.

Do I Need a New EIN?
