1. What is an ITIN?

An ITIN (Individual Taxpayer Identification Number) is a nine-digit tax processing number issued by the Internal Revenue Service (IRS). It is primarily designed for individuals who are required to pay or file U.S. taxes but are not eligible for a Social Security Number (SSN).

• ITINs always start with the number 9.
• Format: 9XX-XX-XXXX.
• Example: 912-34-5678.

Who Needs an ITIN?

• Nonresident aliens filing U.S. tax returns.
• Resident aliens who are not eligible for an SSN.
• Dependents or spouses of U.S. citizens/resident aliens who cannot obtain an SSN.
• Foreign investors in U.S. properties or businesses who must file tax returns.

Purpose of ITIN

The ITIN’s sole purpose is tax processing. It allows individuals without an SSN to:

• File federal income tax returns.
• Pay taxes owed.
• Claim certain tax credits (if eligible).
• Be listed as a dependent on someone else’s tax return.

⚠️ Important: An ITIN does not authorize work in the U.S. and does not provide Social Security benefits or immigration status.

2. What is an EIN?

An EIN (Employer Identification Number) is a nine-digit business tax identification number issued by the IRS to businesses, organizations, and sometimes individuals operating a trade or business.

• EINs are often called Federal Tax Identification Numbers.
• Format: XX-XXXXXXX.
• Example: 12-3456789.

Who Needs an EIN?

• Businesses with employees.
• Corporations, partnerships, and LLCs.
• Nonprofits, trusts, and estates.
• Sole proprietors who want to separate business and personal taxes.
• Foreign nationals starting a U.S.-based business.

Purpose of EIN

The EIN is used to:

• Identify a business entity for tax purposes.
• Open a business bank account.
• Hire employees.
• Apply for business licenses.
• File payroll and corporate taxes.

⚠️ Important: An EIN is for business purposes—not for individual tax identification like an ITIN.

3. Key Differences Between EIN and ITIN

Feature	ITIN (Individual Taxpayer Identification Number)	EIN (Employer Identification Number)
Issued By	IRS	IRS
Format	9XX-XX-XXXX	XX-XXXXXXX
Purpose	Tax filing for individuals without SSN	Tax filing for businesses/entities
Who Can Apply	Non-U.S. citizens, resident aliens, dependents	Businesses, organizations, foreigners
Work Authorization	❌ No	✅ Yes (for business operations)
Used For	Individual tax returns	Business tax returns & hiring

Conclusion: ITIN = for individuals (without SSN). EIN = for businesses/entities.

4. When Do You Need an ITIN?

You need an ITIN if you:

• Are required to file a U.S. tax return but don’t qualify for an SSN.
• Receive U.S.-sourced income (e.g., rental income from property in the U.S.).
• Are a dependent/spouse of a U.S. citizen or resident.
• Need to comply with tax reporting requirements (e.g., foreign investor in U.S. assets).

Example:
Maria, a citizen of Mexico, owns rental property in Texas. She does not qualify for an SSN but needs to pay taxes on her rental income. She must apply for an ITIN.

5. When Do You Need an EIN?

You need an EIN if you:

• Run a business that hires employees.
• Operate a corporation, partnership, or LLC.
• Need to open a business bank account.
• Apply for a business license.
• File employment, excise, or alcohol/tobacco/firearms taxes.
• Are a non-U.S. citizen forming a business in the U.S.

Example:
Ahmed, a citizen of India, starts an e-commerce company in the U.S. He cannot use his ITIN for business tax filing, so he applies for an EIN.

6. Can You Have Both an ITIN and EIN?

Yes, in some cases, you may need both.

• Example: A foreign investor may use an ITIN to file individual taxes and an EIN to report income from their U.S. business.
• ITIN identifies you as an individual.
• EIN identifies your business entity.
