You know, I googled this subject after posting, and checked out this one website where this question was asked....
without looking back at the answer...it's like this....
if your spouse dies and you don't sell the house by the end of the tax year, they use a step up basis to figure the base cost of your house.
Normally, you would use the cost of the house substract from its current fair market value to figure the capital gain.
In this case, you would take 1/2 the original cost of the house, PLUS 1/2 of the fair market value as of the date of the death and you use that as the current base.
I ran those new figures, using several different scenarios, and compared it to the usual way of doing things, and this way, it doesn't seem you incur any significant gain, if any.
Well, that's good. At least this way, someone who has lived in a home and watched it appreciate significantly over the years will not have to pay through the nose if they sell their home.
Maybe they should do the same thing with babies.
