After spending nearly a year researching and estimating the tax implications of finally selling a family rental property I inherited 5 years ago, I think my Federal numbers for 2024 are pretty solid. The property was professionally appraised within a couple months of inheritance, all new improvements and intangibles were tracked and depreciated or amortized as appropriate for the years owned, and capital gains have been proportioned according to land percentage vs. the structure + each asset.
The primary complication is the extensive suspended loss that is now being claimed. Due to this having been a very old and expensive house to maintain, and rental income no longer being sufficient to turn a profit in the few years I owned it, the carryover loss outweighs the capital gain I am reporting by over $40,000. But ok, that finally offsets ordinary income and other non-related carryover losses from prior years and Fed taxes are looking good and as expected.
I just want to make sure I am properly allocating this sale between NY and MI based on my understanding of the tax rules. I had no tax withheld to NY at closing because I calculated (correctly, I believe) that there was no way I would be liable for a capital gains tax after the original step-up in cost basis plus additional improvements and capture of suspended losses. A NYS non-resident return has always been filed for this property no matter who owned it at the time and how much income or loss was reported in any given year. For the past 5 that I owned it, it was always zero and all expenses and rental income was allocated to NY sources and not MI.
So now that all forms and state returns I need are available, I made a fresh dummy return with ONLY the rental sale-related numbers, and when I step through Michigan, for each asset disposal for the MI-4797 form TT pre-populates with Federal gain and recapture to Michigan. When I edit it to 0., TT reflects that on the MI-4797 form, but keeps the "Percentage of Gain Subject to MI Tax" at 100.00 on line 19. Therefore, it appears I am incorrectly multiplying the gains by 0 instead of allocating all at 100%. Everything else appears to be correct as far as how MI treats out-of-state rentals (as business income and losses) on their Schedule 1 of additions and subtractions, and my MI AGI (when adding W-2 income in another dummy return) does show a larger number than Federal. I'm just nervous that the appearance of a self-entered 0 against a TT-filled 100 on the same form as submitted won't support a $0 capital gains tax owed to MI (and NY as well).
Praying someone with some Michigan Income Tax knowledge will show up to alert me to any errors I or TurboTax (Desktop, Mac) is making! I attached a pic of a portion of the MI-4797 I'm referring to. Thanks so much 🙂
