Can You Get an SSN Instead of an ITIN?

An SSN is the better choice if you are eligible. SSNs provide work authorization, access to Social Security benefits, and serve as your universal identifier across US financial and government systems. The IRS does not issue an ITIN to anyone who qualifies for an SSN.

Who Qualifies for an SSN?

US citizens (by birth or naturalization)
Lawful permanent residents (green card holders)
Holders of work-authorized visas: H-1B, H-2A, H-2B, L-1, O-1, TN, E-1, E-2
Certain visa categories with EAD (Employment Authorization Document)

If you are unsure about your eligibility, check with the Social Security Administration before applying for an ITIN. For a complete comparison, see our ITIN vs SSN guide.

Can You Use an EIN Instead of an ITIN?

No. An Employer Identification Number (EIN) is a 9-digit business tax ID that identifies LLCs, corporations, partnerships, and other entities. You cannot use an EIN to file an individual tax return, claim treaty benefits, or complete personal tax forms.

When You Need Both

If you have both personal US tax obligations and a US business entity, you need an ITIN for your individual return and an EIN for your business return. Many non-US entrepreneurs use their ITIN to apply for an EIN online, which is faster than the mail process. See our ITIN vs EIN comparison and guides for LLC owners, freelancers, and Amazon sellers.

Can You Use a Foreign Tax ID for US Tax Filing?

A foreign tax ID has limited use in the US tax system. It can be provided on withholding forms like the W-8BEN for treaty-based withholding reductions. US payers may accept a foreign tax ID for information reporting purposes.

What a Foreign Tax ID Cannot Do

Cannot be used on Form 1040 or Form 1040-NR
Cannot replace an ITIN for individual tax filing
Cannot be used to claim US tax credits or deductions
Is not recognized by the IRS as a taxpayer identification number

If you earn US-source income that requires filing Form 1040-NR, you need an SSN or ITIN. There is no workaround using a foreign-issued number.

Why Is the ITIN Your Only Option?

If you cannot get an SSN and have US tax obligations, the ITIN is your only option for individual tax filing. The IRS designed the system this way. IRC Section 6109 requires every individual filing a US tax return to have either an SSN or ITIN. No other number is accepted on Form 1040, 1040-NR, or 1040-SR.

The good news: the IRS charges $0 to issue an ITIN. Professional services like itin.so simplify the process with document review, Form W-7 preparation, and CAA certification so you keep your original passport. We serve applicants in 150+ countries.
