Get Your ITIN Without the Guesswork

An Individual Taxpayer Identification Number (ITIN) lets you meet US tax obligations, open a business bank account, and stay compliant — even without a Social Security Number. We prepare and submit your application correctly the first time, wherever in the world you're based.

A Straightforward Path to Your ITIN

An ITIN is a nine-digit tax processing number issued by the IRS to individuals who need to file US taxes but aren't eligible for a Social Security Number. It's essential for non-resident LLC owners, foreign investors, and dependents or spouses who need to be listed on a US tax return.

CoFilings® handles the full application from start to finish — reviewing your eligibility, preparing Form W-7, verifying your supporting documents, and submitting everything to the IRS on your behalf. No returned paperwork, no rejected applications, no confusion.

We also support non-US residents who need document certification, tax return coordination, and renewal filing for ITINs that have expired or are about to.

Frequently Asked Questions

What is an ITIN and who needs one?
An ITIN is a tax processing number issued by the IRS to individuals who must file or be listed on a US tax return but don't qualify for a Social Security Number. This includes many non-resident LLC owners, foreign investors, and spouses or dependents of US taxpayers.
Do I need an SSN to get an ITIN?
No. The ITIN exists specifically for people who are not eligible for a Social Security Number but still have a US tax filing requirement.
What documents are required?
You'll typically need a valid passport or a combination of other IRS-accepted identity documents, along with the supporting tax return or exception documentation. We review your specific situation during the consultation.
How long does it take to get an ITIN?
Processing times vary with IRS workload, but most applications are approved within several weeks of submission. We keep you updated on status throughout.
Do ITINs expire and need renewal?
Yes. An ITIN can expire if it hasn't been used on a tax return in the past three consecutive years, or if it falls under an IRS-designated renewal group. We send reminders and handle renewal filings.
Can I use an ITIN to open a bank account?
Many US banks accept an ITIN in place of an SSN when opening a personal or business account. We can guide you through the options available to non-residents.
