How to Get a Tax ID Number in 3 Easy Steps?
Introduction
“There was a point in my life where I hated the idea of business,” one of our clients shared while struggling with compliance and paperwork.
Business success is not only about ideas; it also depends on legal and tax clarity. One of the most basic requirements in this process is a tax ID number.
In this guide, we explain how to get a tax ID number, who needs it, and the key points to keep in mind while applying.
What Is a Tax ID Number?
A tax ID number is a unique identification number used by the Internal Revenue Service to track tax filings and payments. It helps the government identify who is responsible for reporting and paying taxes.There are different types of tax ID numbers depending on the situation. Individuals usually use a Social Security Number.
Businesses typically use an Employer Identification Number. Non-residents may use an ITIN.This number is required for filing taxes, opening bank accounts, receiving payments, and running a business legally.
Do You Need a Tax ID Number?
You may need a tax ID number in several situations, including:
- Running a business as a sole proprietor, partnership, or company
- Hiring employees or paying contractors
- Opening a business bank account
- Applying for business credit or loans
- Operating a nonprofit or trust
- Filing taxes without a Social Security Number
If your activities involve the IRS, a tax ID number is usually required.
Tax ID Number vs EIN: What’s the Difference?
Tax ID Number
A tax ID number is a general term used for different identifiers issued by the IRS. It includes SSN, EIN, and ITIN. These numbers help the IRS track taxpayers and ensure proper compliance.
Tax ID numbers are used for filing returns, reporting income, opening bank accounts, and managing financial records.
Employer Identification Number
An EIN is a specific type of tax ID number issued only to businesses. It is mainly used by companies that have employees or operate as partnerships, corporations, or multi-member LLCs.
An EIN separates business tax obligations from personal taxes and helps with payroll, banking, and reporting.
How to Get a Tax ID Number in 3 Easy Steps?
- Step 1: Check Eligibility
Before applying, confirm eligibility. Your business must be legally formed in the United States or its territories.
The applicant must have a valid taxpayer number such as an SSN or ITIN. This step ensures the IRS can link the tax ID number to the correct entity.
- Step 2: Apply Online
The easiest way to apply for a tax ID number is through the IRS online application using Form SS-4. You will need to provide business details such as name, address, structure, and purpose.
Online applications are quick and reduce the chance of errors.
- Step 3: Receive Your Tax ID Number
If you apply online, the tax ID number is usually issued immediately after submission. Fax or mail applications take longer and may require weeks for processing.
Once issued, you can start using the number for banking, tax filing, and business operations.
How to Get a State Tax ID Number?
A state tax ID number is different from a federal tax ID number. States issue this number for state-level taxes such as sales tax, payroll tax, or state income tax.
To get a state tax ID number:
- Check your state’s tax department website
- Gather your federal EIN and business details
- Submit the application online or by mail
- Wait for confirmation from the state
Requirements and timelines differ by state.
