When navigating U.S. taxes, understanding the distinctions between SSN, EIN, and ITIN is crucial for both individuals and businesses. Let’s break down each identifier and explore who needs them and why.
What is an SSN?
A Social Security Number (SSN) is a nine-digit number issued to U.S. citizens and eligible residents. It’s used for tracking income, tax filings, and government benefits. U.S. citizens, permanent residents, and those with work authorization need an SSN to work, file taxes, and access government services.
What is an EIN?
An Employer Identification Number (EIN) is similar to an SSN but for businesses. The IRS assigns EINs to identify businesses for tax purposes. All types of business entities—LLCs, corporations, and sole proprietors—generally need an EIN for tax filing, even if they don’t have employees. EINs are also essential for opening business bank accounts and setting up payroll.
What is an ITIN?
An Individual Taxpayer Identification Number (ITIN) is issued to individuals who aren’t eligible for an SSN, typically non-resident aliens or dependents of U.S. citizens. ITINs are used solely for tax reporting and don’t grant work authorization or access to Social Security benefits.
Who Needs an SSN?
U.S. citizens, permanent residents, and authorized workers require an SSN. It’s essential for filing individual tax returns, receiving wages, and accessing benefits like Social Security and Medicare.
Who Needs an EIN?
Any business entity that files taxes in the U.S., including LLCs, corporations, and partnerships, needs an EIN. Even sole proprietors without employees may need one for tax filings and bank accounts.
Who Needs an ITIN?
An ITIN is necessary for individuals who can’t get an SSN but must file U.S. taxes, like non-resident aliens or dependents. It ensures compliance with tax regulations but doesn’t permit work or grant Social Security benefits.
Key Differences Between SSN, EIN, and ITIN
- Purpose: SSNs are for individuals, EINs are for businesses, and ITINs are for non-residents without SSN eligibility.
- Eligibility: SSNs are for U.S. citizens or eligible residents; EINs are for businesses; ITINs are for individuals ineligible for an SSN.
