In the United States , in early January 2018, Sarah was paid for three portraits she painted and delivered in late 2017. During 2018, Sarah completed 14 portraits. Payment was received for 11 portraits when they were delivered to the buyers. One portrait was delivered in mid2018 to the CEO of a company who promised payment within 30 days. Payment was never received, and the company has since entered bankruptcy. Since the CEO has been indicted for securities fraud, Sarah feels certain that she will never be paid for the portrait. The final two portraits were delivered in late 2018, and payments for both were received in early 2019. In December 2018, Sarah accepted $3,200 as payment for a portrait to be done in 2019. Although she did not like the arrangement, the customer said the prepayment was motivated by anticipated cash-flow considerations.

Sarah keeps receipts for all her expenses. Her total cost for painting supplies in 2018 was $3,010 (e.g., for canvases, brushes, oil paints, smocks, palettes, and other art supplies). The framing of the finished portrait is left to the customer since the most appropriate frame is a matter of personal taste and consideration for where the painting will be exhibited.

For convenience and security reasons, Sarah prefers to work at home. One-fourth of the 4,000 square-foot living area is devoted to Sarahs studio. The Clarks built the home at a cost of $350,000 on a lot previously acquired for $100,000, and they moved in on June 15, 2015. As to business use, depreciation is based on MACRS (using the midmonth convention) applicable to 39-year nonresidential realty. Besides home mortgage interest and property taxes (see item 19 below), residence expenses for 2018 are summarized below.
