I assume your new job is in Virginia. Most likely you have neglected to apportion your total income between DC and Virginia on the DC tax return. Please return to the DC interview and go through it again. You will eventually see a screen asking you to indicate how much of your total income was earned in DC. After completing the DC return, go through the Virginia return interview again and make any needed corrections.
Please read on for more information.
