State tax filing

You can indicate in the Personal Info section that you moved during 2025 or you can indicate in each state Virginia and DC that you need to change your state residency.  

You will have to allocate the wages based on where you were a resident when you earned them.  Because your employer withheld for Virginia all year, you should get a refund but will owe DC.  If you have not already done so, make sure you request your employer withhold DC taxes if they do so you do not have to file a nonresident Virginia return.  (Virginia and DC have a reciprocal agreement so you can file and pay taxes to your resident state only so you do not have to file two state tax returns.)
