I started the 2021 living and working in Maryland, as I have for the last 5 full years. In September '21 I moved to DC while continuing my job in Maryland and my employer continued to withhold Maryland State taxes since I never updated my state tax documents with them. How will this affect my tax filing for FY21? And what forms do I need to submit to my employer to have taxes properly withheld in DC for FY22? Thanks for any clarity with this.
