My parents started a grocery store business in 1978. Many years later, it was converted to an S Corp. Years later, my parents gifted myself and two siblings 10% (100 shares) each. That was increased to 13% (130 shares). In 2009, the 130 shares were redeemed and replaced with 100 shares. No money was issued or required for the transaction. In November of 2024, the 100 shares were sold to the S Corp for a cash value. My question is how do I determine my cost basis for shares given, shares retrieved and replaced, and eventually shares sold to the corporation?
