The four chapters in this part discuss investment gains and losses,
including how to figure your basis in property. A gain from selling or trading
stocks, bonds, or other investment property may be taxed or it may be tax free,
at least in part. A loss may or may not be deductible. These chapters also
discuss gains from selling property you personally use — including the
special rules for selling your home. Nonbusiness casualty and theft losses are
discussed in
chapter 25 in Part Five.
