David earned consulting fees of $$145,000$ in $2023.$ He maintains his own office and pays for all business expenses. The Coles are adequately covered by the medical plan provided by Ella's employer but have chosen not to participate in its $401($k$)$ retirement plan. David's employment$-$related expenses for $2023$ are summarized below: Airfare $$8,800$ Lodging $4,990$ Meals from restaurants $($during travel status$)2,400$ Entertainment $3,600$ Ground transportation $($e$.$g$.,$ limos$,$ rental cars, and taxis$)800$ Business gifts $900$ Office supplies $($includes postage, overnight delivery, and copying$)1,500$ The entertainment involved taking clients to sporting and musical events. The business gifts consisted of $$50$ gift certificates to a national restaurant. These were sent by David during the holidays to $18$ of his major clients.

In terms of depreciation, the Coles use the MACRS percentage tables applicable to $39-$year nonresidential real property. As to depreciable property $($e$.$g$.,$ office furniture$),$ David tries to avoid capitalization and uses whatever method provides the fastest write$-$off for tax purposes. 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$).$ Assume that Ella is an employee $($not an independent contractor$).$ Besides her transportation, she must provide and maintain her own uniforms.

Unknown to Ella and David, Sarah had a life insurance policy and a savings account $($with David as the designated beneficiary of each$).$ In $2022,$ the Coles purchased two ATVs for $$14,000.$ After several near mishaps, they decided that the sport was too dangerous.
