Name, Address, and Social Security Number

You must disclose your legal name and Social Security number (SSN) on your Utah income tax return. Your name(s) and the Social Security number(s) entered on your Utah return must match your Social Security card(s).

If you do not have a legal Social Security number, you must use an Individual Taxpayer Identification Number (ITIN) issued by the Internal Revenue Service in place of the Social Security number.

Married non-resident aliens not required to have an SSN or ITIN number for their spouse should file their Utah return with a “Single” filing status.

Do not use “Applied For” or other placeholders as your SSN or ITIN on the Utah return.  If you have not yet received your SSN or ITIN pay any taxes due by the due date of the return and file the return once you have been issued the identity number.

Name and Social Security Number

Enter your Social Security number and name in the spaces provided. If you are filing a married-filing-jointly or a married-filing-separately return, enter your spouse’s name and Social Security number also. Enter Social Security numbers in the same order your names appear on the form and on the federal return.


Enter your United States Postal Service approved address in the space provided. Use your “ZIP plus four” nine digit zip code without a hyphen. This is a postal service requirement.

If your address is in a foreign country, enter the street address where indicated and the foreign city, state/province, and postal code all in the city field (abbreviate if necessary). Enter only the foreign country name in the “Foreign Country” field and leave the “ZIP code” field blank.

Phone Number

Enter your ten-digit phone number without parentheses or hyphens.


All information on the income tax return is confidential and protected from unauthorized disclosure by federal and state laws. You must provide your name, Social Security number, and address on the return, but Utah will use a state assigned account number in any correspondence to avoid disclosure of your Social Security number.
