Question 1

What is an ITIN and who needs one?

Accepted Answer

An Individual Taxpayer Identification Number (ITIN) is a 9-digit number issued by the IRS to individuals who are required to file a US tax return but are not eligible for a Social Security Number (SSN). This includes non-resident aliens, Canadian residents with US income, spouses and dependents of US residents, and others with US tax obligations.

Question 2

Can I get an ITIN without mailing my passport?

Accepted Answer

Yes — if you work with an IRS Certifying Acceptance Agent (CAA). As a CAA, Zenith Financial can verify and certify your original identity documents in person, so you never have to mail your passport to the IRS. This is a significant advantage for cross-border clients.

Question 3

How long does it take to get an ITIN?

Accepted Answer

The IRS typically processes ITIN applications within 7 weeks when filed correctly. During peak tax season (January-April), processing can take up to 11 weeks. We recommend applying as early as possible if you need the ITIN to file your tax return by the deadline.

Question 4

Does an ITIN expire?

Accepted Answer

Yes. ITINs that have not been used on a federal tax return at least once in the last three consecutive years expire. Also, ITINs with middle digits 70-88, 90-99 have been deactivated and must be renewed. We help you determine if your ITIN is still valid.

Question 5

Do I need an ITIN if I sold US real estate?

Accepted Answer

Yes. Non-US residents who sell US real estate are subject to FIRPTA (Foreign Investment in Real Property Tax Act) withholding. You need an ITIN to file a US tax return and claim any withholding refund. We handle the full FIRPTA and ITIN process for Canadian residents selling US property.

Question 6

Can my Canadian spouse get an ITIN to file jointly?

Accepted Answer

Yes. If a US citizen or resident wants to file a joint tax return with a non-resident alien spouse, the spouse must obtain an ITIN. Filing jointly often results in a lower tax rate. We handle ITIN applications for non-resident spouses as part of our cross-border tax preparation service.
