A mid-year move usually splits the year into a resident period in each state and points toward two part-year returns - commonly on part-year or dual-status forms you should confirm for each state.

A domicile change is decided on objective ties, not just a new address; the state you left commonly presumes you are still domiciled there until the ties clearly shift to the new state.
With no retained abode or ties, file a part-year resident return in each state and retain dated proof of the move to support the domicile change under each state's part-year residency rules.

Many income-tax states apply a statutory-residency rule - keep a place of abode plus spend more than about 183 days there and they can tax you as a full-year resident regardless of domicile; confirm each state's day-count rule.
A place of abode plus more than 183 days meets the statutory-residency test, so the old state can tax you as a full-year resident; relieve the double tax with a resident credit under Comptroller of the Treasury of Maryland v. Wynne, 575 U.S. 542 (2015). Statutory residency does not apply, so the position rests on domicile; build a dated domicile-change file to carry your burden of proving the move under each state's domicile rules.

Two homes plus heavy day counts can make you a resident of two states at once - a domicile state and a statutory-residency state - which is the classic setup for the same income being taxed twice.
Two states may each treat you as a resident, so compute the resident credit each way; Comptroller of the Treasury of Maryland v. Wynne, 575 U.S. 542 (2015) requires a credit to relieve the double tax, though it may not fully cover intangible income.

Nonresidents are generally taxed on state-source income, and a few states apply a convenience-of-the-employer rule that can tax remote wages by the employer's state even when you never work there.
File a nonresident return sourcing the income to that state and claim a resident credit at home under Comptroller of the Treasury of Maryland v. Wynne, 575 U.S. 542 (2015); check for a convenience-of-the-employer rule and any reciprocity agreement. File a single resident return and monitor the triggers - a second home, a day-count threshold, cross-border work, or out-of-state income - that would create a nonresident or part-year filing.
