Work in VA but residences in VA and DC

[metrixtech]

My permanent home is in DC.  Starting the beginning of this year, my employer transferred me to a two-year Virginia location which is too far to commute.  I have rented an apartment in VA and live there most of the time, surely > 183 days per year.  For tax purposes, how do I handle the two residences, which residence is used as the official filing address, which state should be withholding state taxes and which state tax returns should I be completing?  Thanks.

You are still a DC resident and only need to file a DC return. Only DC withholding should be done.  DC & VA have a reciprocal agreement, so no VA tax is  required.

Thanks for your response, but I have received conflicting information that says if I spend more than 183 days per year in Virginia that makes me a VA resident in the eyes of VA's tax law and, therefore, makes me subject to VA state taxes.  In prior years, when I worked at a VA location to which I commuted daily from DC, I leveraged the reciprocal agreement.  I just want to clarify my current state tax obligation now that I'm living in VA most of the time for work purposes, but still maintaining my DC home.
