Navigating the world of taxes often requires you to provide a Taxpayer Identification Number (TIN). Whether you’re filing your annual tax return, claiming treaty benefits, or setting up a business, understanding what a TIN is and, crucially, where to find your tax ID number is essential. This guide will clarify the different types of TINs and pinpoint where you can locate yours.
Understanding Taxpayer Identification Numbers (TINs)
A Taxpayer Identification Number (TIN) is a unique number used by the Internal Revenue Service (IRS) to administer tax laws. Think of it as your tax fingerprint. It’s issued either by the Social Security Administration (SSA) or directly by the IRS, depending on the type of TIN. While the Social Security number (SSN) is perhaps the most familiar TIN, it’s important to understand that other types exist, each serving a specific purpose.
Types of Taxpayer Identification Numbers
There are several types of TINs, each designed for different individuals and entities:
Social Security Number (SSN)
Your Social Security Number (SSN) is issued by the Social Security Administration (SSA). It’s primarily used for individuals, U.S. citizens, and permanent residents authorized to work in the United States.
Where to find your SSN:
- Social Security Card: The most direct place to find your SSN is on your Social Security card. Keep this card in a safe place and avoid carrying it with you regularly to prevent loss or theft.
- Tax Returns: Your SSN will be on your filed tax returns, typically on Form 1040.
- W-2 Forms: Your Wage and Tax Statement (Form W-2) provided by your employer will also display your SSN.
- Pay Stubs and Other Official Documents: Some pay stubs and official documents from employers or government agencies may include your SSN.
How to get an SSN: If you need to obtain an SSN, you can apply by completing Form SS-5, Application for a Social Security Card PDF. You will need to provide proof of identity, age, and U.S. citizenship or lawful alien status. For detailed information, visit the Social Security Administration website. You can also obtain Form SS-5 by calling 800-772-1213 or visiting your local Social Security office. These services are free.
Employer Identification Number (EIN)
An Employer Identification Number (EIN), also known as a Federal Tax Identification Number, is used to identify business entities, estates, and trusts.
Where to find your EIN:
- IRS Notice CP 575, EIN Confirmation Letter: When you successfully apply for an EIN, the IRS sends a confirmation letter, Notice CP 575, which contains your EIN. This is often the first and most reliable place to find it.
- Business Bank Account Documents: When opening a business bank account, you’ll typically provide your EIN. Bank account statements and related documents may display your EIN.
- Business Credit Card Applications and Statements: Similar to bank accounts, business credit card applications and statements may also include your EIN.
- Previously Filed Business Tax Returns: Your EIN will be on any business tax returns you have previously filed, such as Form 1120 (for corporations) or Form 1065 (for partnerships).
- Official Business Documents: Legal documents related to your business formation, such as articles of incorporation or partnership agreements, may include your EIN.
How to get an EIN: To obtain an EIN, you can apply online through the IRS website, by phone, by fax, or by mail using Form SS-4, Application for Employer Identification Number. Refer to the IRS’s Employer ID Numbers page for detailed instructions. For employers in Puerto Rico, Form SS-4PR PDF is available.
Individual Taxpayer Identification Number (ITIN)
An Individual Taxpayer Identification Number (ITIN) is a tax processing number for certain nonresident and resident aliens, their spouses, and dependents who are not eligible for an SSN. It’s a 9-digit number starting with “9” and formatted like an SSN (NNN-NN-NNNN).
Where to find your ITIN:
- IRS Notice CP 565, ITIN Assignment Letter: The IRS issues a notice, CP 565, when your ITIN application is approved. This letter is your primary source for your ITIN.
- Previously Filed Tax Returns: Your ITIN will be on any tax returns you have filed with the IRS.
How to get an ITIN: To apply for an ITIN, you must complete Form W-7, IRS Application for Individual Taxpayer Identification Number. The form requires documentation verifying your foreign status and identity. You can mail the application and documentation, present them at IRS walk-in offices, or process your application through an Acceptance Agent authorized by the IRS. The IRS also provides an Interactive Tax Assistant tool to help determine if you need an ITIN.
Adoption Taxpayer Identification Number (ATIN)
An Adoption Taxpayer Identification Number (ATIN) is a temporary nine-digit number issued by the IRS to individuals in the process of legally adopting a U.S. citizen or resident child who cannot obtain an SSN for the child in time for filing taxes.
Where to find your ATIN:
- IRS Letter Assigning ATIN: The IRS will send a letter assigning you an ATIN upon successful application. Keep this letter for your records.
- Adoption Agency Records: Your adoption agency may also have a record of your ATIN, especially if they assisted with the application process.
How to get an ATIN: Apply for an ATIN using Form W-7A, Application for Taxpayer Identification Number for Pending U.S. Adoptions. Note that Form W-7A is specifically for U.S. citizen or resident children.
Preparer Tax Identification Number (PTIN)
A Preparer Tax Identification Number (PTIN) is required for paid tax preparers. If you are a paid tax preparer, you must use a valid PTIN on the tax returns you prepare.
Where to find your PTIN:
- IRS Online Account: Tax preparers can find their PTIN in their IRS online account used for PTIN registration and renewal.
- PTIN Renewal Confirmation: When you renew your PTIN, you will receive a confirmation that includes your PTIN.
- IRS Records: If you are unsure of your PTIN, you may be able to retrieve it through IRS professional tax preparer resources or by contacting the IRS directly.
How to get a PTIN: If you need a PTIN, you must register through the IRS online system. Even if you had a PTIN before September 28, 2010, you need to apply for a new or renewed PTIN through the new system. For those who prefer not to apply online, Form W-12, IRS Paid Preparer Tax Identification Number Application is available.
Why You Need Your Tax ID Number
Providing your TIN is mandatory on various tax-related documents. You will need to furnish your TIN in situations such as:
- Filing Tax Returns: Whether you are filing individual income tax, business tax, or estate tax returns, your TIN is required for identification and processing.
