IRA Deduction: I moved to Delaware in Jun last year, how do I allocate my IRA deduction

[Kevinjjfr]

Hi everyone! I moved to Delaware last year in June. I contributed 5k to my Traditional IRA in Dec, and 5k is all deductible. When filing the Delaware tax, how do I allocate the Delaware Amount? Should I allocate half based on my DE residency period, or 5k as I contributed in Dec while I was a DE resident.

Allocated based on your residency when you made the contribution. From what you said, it sounds like 100% DE.
