On July 1, YEAR 1, Linus sold his profits and capital interest to Sally for $65,000. On the date of the sale, Linus's adjusted outside tax basis in his partnership interest was $45,000 (after adjusting his basis for items that increased or decreased his basis throughout the first half of the year).
