This was covered in the other linked topic too.
Below is how to handle the assets, and please DON"T added the old and new basis together and start over.
You have to allow the program to calculation the depreciation through the DOD and then take it out of service. Then divide the cost and accumulated depreciation in half to arrive at the husband's original share of cost and a/d to be reentered because that will continue on at half value of the original cost and half the a/d already taken. THEN, also enter one-half of the "stepped" FMV that was inherited from the spouse as the basis without any accum depreciation to start, use the DOD as the starting date because depreciation starts over on the portion that husband inheritied.
In other words, for this year the depreciation schedule will have the original depreciable assets through DOD AND 2 components for the time after DOD on the depreciation schedule for each asset that was owned.
As an example, let's assume a house with a cost of $160, a/d at BOY of $55, current deprec of $1 calc'd through DOD, a/d at DOD of $56, and a FMV of $350.
Your depreciation schedule will show these lines:
House, cost $160, a/d BOY $55, current deprec $1 (allow system to calc the partial year deprec), a/d at DOD $56 - out of service at DOD (or disposed with no gain, however ATX handles that)
House (for H's orig. share), USE ORIG DATE IN SERVICE, cost $80, a/d (at DOD) $28, current depreciation calculated for portion of year after DOD and you will have to override this to report the proper partial year amount
House (for stepped up inherited portion), use DOD as date in service, basis $175, a/d -0-, allow system to calc depreciation for current year that will be from DOD through year-end
IF he happens to sell the house within one year, you will have to override that gain to tell the system that the gain on the stepped up portion is also long-term because inherited assets get long-term treatment, but after one year, that won't be an issue any more.
