@Hal_Al & @Critter-3 --
From page 13 of the 2021 Instruction Booklet for Indiana Form IT-40PNR, the part-year resident return, Lines 1 and 2 instructions:
"Note for part-year or full-year nonresidents. Do not enter that portion of your Indiana source wage, salary, tip or commission income in Column B earned while you were a resident of a reciprocal agreement state (see Reciprocal States: Special Filing and Income Reporting Instructions on page 8)."
Apparently the MI-IN reciprocity agreement does indeed apply to part-year residents.
**Answers are correct to the best of my ability but do not constitute tax or legal advice.
