Home sale

If you made a gain on the sale (your proceeds from the sale exceed your cost basis in the home) you report the sale on A Schedule D of your Form 1040, unless (a) this was your principle residence for at least two of the preceding fives years, and (b) the gain on the home is less than $250K ($500K if married diling jointly), and (c) you have not already used this exclusion in the past two years. If you are selling the home at a loss there is nothing to report (you can not deduct losses on personal property). Full detals are in Pub 523:
