This is an old post. The correct way to handle this situation:
Below are some common duplicate wage situations that are handled on this screen.
Example 1 - One line listed on screen contains NJ:
Check the boxes for lines other than NJ and they will be removed. (You may need to leave NJ and another state too if the total income is split between the states and taxable to NJ.)
Example 2 - No state listed is NJ:
- Scenario #1 - Add up the state wage amounts for the W-2 on the screen and see if the total of all states is close to the federal amount in the text at the top of the screen. If it is, then you don't need to check any boxes to remove wages from the W-2. It is OK if the number is over or under the fed amount if you have payroll deductions/credits on the W-2 (such as a 401K or other information in box 12 that is not allowed in NJ).
- Scenario #2 - Look for a state line that is closest to the fed amount. When in doubt, use the larger of the state lines that are closest to the fed wages. Check all other lines to remove them from being taxable in NJ.
Note: In some cases if a specific line for NJ is not on the W-2 you may need to adjust these state wages on the screen titled: "Other Income". The most common wage adjustment would be for retirement pre-tax contributions other than to a 401K listed in box 12 of your W-2, but there are other adjustments there that may also need to be included as income in NJ when they are not included for federal or another states taxable wages.
