Hi Ernie,
Thanks for the information. Based on some of your questions, you mentioned a few options. Would the simplest option just to file as if I just moved to SC on March 1, 2021 permanently (without worrying about coming back to VA for any part of the year?) Meaning, I file VA as a part-time resident from Jan 1 - Mar 1, 2021, and file SC from Mar 1 - Dec 31, 2021? OR would it be easier (if allowed) to file as full-time VA resident for 2021 based on "tax home" you mentioned (but how do I PROVE that I spent the time at my brother-in-laws as I didn't get any mail there - is my word enough?) and not worry about filing in SC, since I'd be claiming VA as my full-time residency (>183 days)? But, even if I do the last option, do I still have to file in SC too since I did work there for the other part of the year (claiming the credit that you mentioned)? I understand that if I file as a full-time VA resident, I don't have to file in MD (reciprocity), but if some of my time was in SC (do I have to pay SC some tax too, and if so, do I then need to file a non-resident return to MD for the pay I received while working in SC?? When the situation with my brother is complete, I do intend to go back to SC full time.
Sorry for the complicated question and follow up, I just want to do what's right/correct.
