Who needs a federal tax id number

As of February, 2003, SRM Domestic Customers are required to submit their Tax Identification (TIN) number. Please see the following Frequently Asked Questions (FAQ) for information.

What is a TIN/EIN?

Taxpayer Identification Number (TIN) and Employer Identification Number (EIN) are defined as a nine-digit number that the IRS assigns to organizations. The IRS uses the number to identify taxpayers who are required to file various business tax returns. TIN/EIN are used by employers, sole proprietors, corporations, partnerships, nonprofit associations, trusts, estates of decedents, government agencies, certain individuals, and other business entities.

I am confused, are TIN/EIN the same thing?

A Federal Tax Identification Number, also known as a "95 Number", "E.I.N. Number," or "Tax I.D. Number", all refer to the nine digit number issued by the IRS. They are different names for the same number.

Why do you need our TIN/EIN number?

NIST is implementing a new financial management system and will be consolidating customer records from many different sources. In an effort to keep the central database manageable we are trying to limit the number of duplicate entries in our customer database. TIN/EIN will serve as a way to uniquely identify a business entity when the precise name of a business entity is unknown or when it is difficult to distinguish it from other businesses with similar names.

Our company is exempt from taxes on purchases; can you accept our tax exemption certificate/number?

No, we are not using the number for tax purposes and the tax exemption number will not provide us with the necessary information to determine if you are an existing customer in our database.

Our company is exempt from taxes on purchases; therefore you should not need my TIN/EIN number.

Our request has nothing to do with tax status. Our main goal in obtaining and storing TIN/EIN information is to make our NIST centralized customer database as efficient as possible.

I do not have a TIN/EIN number.

Are you sure? TIN/EIN numbers are used by domestic employers, sole proprietors, corporations, partnerships, nonprofit associations, trusts, estates of decedents, government agencies, certain individuals and other business entities. If your company falls into one of these categories you should have a TIN/EIN number.

I only placed one SRM order and I don't anticipate ordering anything else. Do you still need my TIN/EIN number?

When you file your tax return or need to talk to the IRS, you’ll likely have to provide a tax identification number, which is also called a TIN or tax ID number. Here’s what a tax ID number is and how to apply for one.

A tax identification number, or TIN, is a unique nine-digit number that identifies you to the IRS. It's required on your tax return and requested in other IRS interactions. Social Security numbers are the most popular tax ID numbers, but four other kinds are popular too: the ITIN, EIN, ATIN and PTIN.

Individual taxpayer identification number (ITIN)

What it is: An individual taxpayer identification number, or ITIN, is a nine-digit tax ID number for nonresident and resident aliens, their spouses and their dependents who cannot get a Social Security number. The IRS issues the ITIN.

How to get an ITIN: To get an ITIN, fill out IRS Form W-7. You must prove your foreign/alien status and identity. Also, you must supply a federal income tax return to your Form W-7 (there are some exceptions; the instructions to the W-7 have the details). Organizations called “acceptance agents” have IRS authorization to help people get ITINs.

• ITINs always begin with the number 9.

• Expirations: Any individual tax ID number not used on a tax return at least once for tax years 2018, 2019 or 2020 expired at the end of 2021. ITINs with middle digits containing 70 through 88, and 90 through 99 (if assigned before 2013), have also expired. [0]

Employer identification number (EIN)

What it is: An employer identification number, or EIN, is a tax ID number for businesses that have employees; are corporations or partnerships; withhold taxes on income paid to nonresident aliens; have Keogh plans; are involved with certain types of organizations; or file employment, excise, or Alcohol, Tobacco and Firearms tax returns. The principal business must be in the United States or a U.S. territory, and the person applying for the EIN (it must be an individual, not an entity) must already have a Social Security number, ITIN or other EIN. The IRS may require an estate or trust to get an EIN.

How to get an EIN: You can apply for this tax ID number online with the IRS. You can also fill out IRS Form SS-4 and fax it or mail it to the IRS. International applicants can call 1-267-941-1099 to get an EIN.

Note: Your business may also need a separate state employer ID number.

Adoption taxpayer identification number (ATIN)

What it is: An adoption taxpayer identification number, or ATIN, is a temporary, nine-digit tax ID number the IRS gives to people who are in the process of adopting a child. The IRS provides the number if the adopting parents cannot get a Social Security number for the child in time to file their tax return. The number identifies the child, not the parent, and is needed for the parent to claim the child as a dependent.

How to get an ATIN: To get an ATIN, file IRS Form W-7A. You’ll need to attach a copy of the placement documentation. The child must be legally placed in your home for adoption. If you’re adopting a child from another country, you can still get an ATIN, but there are more rules (see the details here).

• You cannot claim the earned income tax credit with this tax ID number (you can only use a Social Security number to do that).

• It takes four to eight weeks to get an ATIN once the IRS gets your Form W-7A, so ask for it well before your tax return is due.

• Unless you notify the IRS that the adoption is still pending, the IRS will automatically deactivate an ATIN after two years.

Preparer tax identification number (PTIN)

What it is: A PTIN is a preparer tax identification number. The IRS requires anyone who prepares or assists in preparing federal tax returns for compensation to have a PTIN. Tax preparers must put their PTIN numbers on clients’ tax returns.

How to get a PTIN: Preparers can get PTINs from the IRS online in about 15 minutes. Alternatively, they can fill out and mail IRS Form W-12. That method takes about four to six weeks.
