I now spend more time at my house in SC than at my NJ house, so my primary home is in SC. However for state tax residency purposes both SC and NJ are domicile-based states. NJ always remains my domicile state, so for my NJ state return I must file as a NJ resident. However due to my primary home being in SC, I am not eligible for a NJ return property tax deduction for my NJ property taxes paid.
So for the TT Online question about eligibility for a NJ property tax deduction I answer "No", but TT still incorrectly applies a NJ property tax deduction, and takes the wrong column for other taxes paid in Schedule NJ-COJ form, for my NJ state return. How do I get TT to correctly recognize I'm not eligible for NJ property tax deduction?
TT Online form entry
Eligibility - Property Tax Deduction or Credit
Requirements: Your primary residence during 2024 was in New Jersey [+ others]
Do you meet all the requirements? -> I answer "NO"
FYI I found this was due to my input error. For additional property tax screen (ie tax not entered for a lender's 1098), you have option to enter property taxes paid either on your "main home" aka primary residence, or on "additional homes or land". I had incorrectly entered my NJ taxes in the main home box - moved taxes to the additional homes, and NJ state deduction was correctly not taken.
