Sale of Personal Residence

What is the name of your state? Ohio

A and B, siblings, own property used as A's primary residence as tennants in common. Can A utilize $250,000 exckusion of gain? What if B transfers ownership to A for some other property and then A sells (within a few months)?

A can exclude the gain on A's half of the profits. B cannot.

In the second scenario, A does not meet the 2/5 year use & ownership test on B's half of the house & pays taxes on those profits.

What if B moves in & A moves out & they wait 2 years to sell? Now both meet the 2/5 year ownership & use test.
