Lucia is a 69 years old single individual who receives a taxable pension of $10,000 per year and Social Security benefits of $7,000. Lucia is considering the possibility of selling stock she has owned for years and using the funds to purchase a summer home. She will realize a gain of $20,000 when she sells the stock, which has been paying $1000 of dividends each year. Lucia says her brother recommended that she sell half of the stock this year and half next year because selling all of the stock at once would affect tax treatment of her Social Security Benefits. A) Compute her AGI under the assumption she sells all of the stock now after receiving $1000 dividends from the stock. B) Repeart the computation uder the assuption she sells only half of the stock this year and also receives $1000 dividend from the stock.
