#Good news! The IRS has extended the tax deadline to April 18th! As long as you submit your federal return by midnight on 4/18/2018, you won't be considered a late filer for your federal return. Direct debit tax payments that are submitted with your federal return (or on the IRS website) by 4/18 are also considered timely filed ×

Why do I need to enter my social security number?

Your Social Security number (SSN) is a unique way to identify you, which makes it key to locating your credit files.

In most cases, the last 4 digits of your SSN, along with the other personal information you enter, will be enough to match your identity with your Equifax and TransUnion credit files. In some cases, though, we may need your full SSN to ensure a correct match.

Rest assured that we’re committed to keeping your info safe. If you have any concerns about the security of your information, check out our security page.

Can I use my Tax Identification number to register?

We cannot accept an Individual Tax Identification number (ITIN). Credit Karma Tax is only available to U.S. residents with a Social Security number. An ITIN always begins with the number 9 and has a 7 or 8 in the fourth digit, for example 9XX-7X-XXXX or 9XX-8X-XXXX. If you get denied for a SSN, you can apply for an ITIN using Form W-7. It’s important to know that an ITIN can expire if it’s not included on a U.S. tax return for 3 consecutive tax years, and you cannot claim the Earned Income Credit (EIC) if anyone listed on your return uses an ITIN. Here’s more information about an ITIN on the IRS website.
