He purchased the Expedition on August 15, 2018, and has always used the automatic (standard) mileage method for tax purposes. Parking and tolls relating to business use total $340 in 2021. When the Coles purchased their present residence in April 2018, they devoted 450 of the 3,000 square feet of living space to an office for David. The property cost $440,000($40,000 of which is attributable to the land) and has since appreciated in value. Expenses relating to the residence in 2021 (except for mortgage interest and property taxes; see below) are as follows: In terms of depreciation, the Coles use the MACRS percentage tables applicable to 39-year nonresidential real property.

Ella works at a variety of offices as a substitute when a hygienist is ill or on vacation or when one of the clinics is particularly busy (e.g., prior to the beginning of the school year). Besides her transportation, she must provide and maintain her own uniforms. Her expenses for 2021 appear below. Ella's salary for the year is $42,000, and her Form W-2 for the year shows income tax withholdings of $4,000 (Federal) and $1,000 (state) and the proper amount of Social Security and Medicare taxes. - Besides the items already mentioned, the Coles had the following receipts during 2021. For several years, the Coles' household has included David's divorced mother, Sarah, who has been claimed as their dependent. In late December 2020, Sarah unexpectedly died of a heart attack in her sleep. Unknown to Ella and David, Sarah had a life insurance policy and a savings account (with David as the designated beneficiary of each). In 2020, the Coles purchased two ATVs for \$14,000. After several near mishaps, they decided that the sport was too dangerous. In 2021, they sold the ATVs to their neighbor. - Additional expenditures for 2021 include: In 2021, the Coles made quarterly estimated tax payments of $6,000 (Federal) and $500 (state) for a total of $24,000 (Federal) and $2,000 (state). Using the appropriate forms and schedules, compute the Coles' Federal income tax for 2021. Disregard the alternative minimum tax (AMT) and various education credits since these items are not discussed until later in the text (Chapters 12 and 13). Relevant Social Security numbers are: The Coles have never owned or used any virtual currency. The Coles received the appropriate coronoavirus recovery rebates (economic impact payments); related questions in ProConnect Tax should be ignored. They do not want to contribute to the Presidential Election Campaign Fund. Also, the Coles want any overpayment of tax refunded to them and not applied toward next year's tax liability. David will have a self-employment tax liability; refer to Exhibit 13.9 in Chapter 13 to compute this liability. Suggested software: ProConnect Tax
