2011 IRS Form W-2, Box 15, shows the state claimed by a member for state tax purposes. Box 15 contains an employer's state ID number. 2011 W-2 forms issued by the Coast Guard to Utah residents show an employer state ID number of W83421.
The State of Utah has changed the Coast Guard's state ID number from W83421 to 12485340002WTH. The state will still accept the old number; however, if you file your state taxes through certain software (such as TurboTax), you will be asked to enter the employer's state ID number. You will need to enter 12485340002WTH instead of W83421.
All other information on your W-2 is correct.
