An Individual Taxpayer Identification Number (ITIN) is a nine-digit number assigned by the Internal Revenue Service to taxpayers who are not eligible to obtain a Social Security Number (SSN). Individuals must have a filing requirement and file a valid federal income tax return to receive an ITIN, unless they meet an exception. It is used for tax purposes only.

To enter information for Form W-7 Application for IRS Individual Taxpayer Identification Number in the TaxAct^® program:

1. From within your TaxAct return (Online or Desktop), click Federal. On smaller devices, click in the upper left-hand corner, then click Federal.
2. Click Basic Information in the Federal Quick Q&A Topics menu to expand, then click Form W-7 - ITIN Application.
3. Click + Add Form W-7 to create a new copy of the form or click Edit to review a form already created.
4. Scroll down to answer all applicable questions in the new window, then click Save & Close.

As the TaxAct program requires a valid ITIN to calculate certain credits and deductions (i.e. Child Tax Credit), enter a dummy ITIN of "999-88-9999" for individuals who do not yet have an ITIN. This ensures the return is calculated correctly for an individual that will be receiving an ITIN. When you print the return, be sure to white out the dummy ITIN(s) from anywhere they appear in the return before mailing the Form W-7 application (and the attached tax return) to the IRS ITIN Operation Service Center.

For filing with some states, it may be possible to paper file the state return and send a copy of both the Form W-7 (ITIN application) and the Federal return. The state will let you know if they need additional information or if they prefer you wait to file your state return after receiving the ITIN from the IRS. You can check with your state Department of Revenue office to verify their preference.

Note. Your ITIN may expire before you file a tax return for the current tax year. All ITINs not used on a federal tax return at least once in the last three years will expire on December 31 of the tax year. All ITINs with middle digits of 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87 and 88 (such as "9XX-73-XXXX") are now expired.
