In 2022, Ian and Isabella donated Stock A to a public charity (50% organization). Stock A had a fair market value of $80,000, and Ian and Isabella purchased Stock A many years ago for $1,000. What is Ian and Isabella's 2022 charitable contribution deduction (after application of the limitation) if, in 2022, Ian and Isabella had gross income of $110,000 and adjusted gross income of $100,000? What would the charitable contribution deduction be if instead Stock A was worth $1,000 at the time of donation, and Ian and Isabella purchased Stock A years ago for $80,000? What if instead of donating stock, Ian and Isabella donated $80,000 cash to the charity in 2022? Their AGI is still $100,000.
