Self-Check

Do You Need an ITIN? A Quick Self-Check

Before answering, check whether any of these situations apply to you.

First, you do not have an SSN (Social Security Number) and are not eligible for one — and you either must provide a federal tax identification number or must file a federal tax return.

Second, do you fall into one of these groups?

If any of these applies to you, you must apply for an ITIN.

Of course, the main prerequisite is filing US taxes or needing a federal tax identification number. If you have no US filing obligation and don't need to provide a federal tax ID, you may not need an ITIN.

One more thing to plan for: because the IRS processes ITIN applications slowly, and the notice travels by regular mail, it usually takes about 10–15 weeks. If you intend to invest or do business in the US, pay attention to this timeline and start your ITIN application as early as possible.
