Enter the amounts you paid for farm labor. Do not include amounts paid to yourself. Reduce your deduction by the amounts claimed on:
Include the cost of boarding farm labor but not the value of any products they used from the farm. Include only what you paid household help to care for farm laborers.
Also, reduce your deduction by the nonrefundable and refundable portions of the new CARES Act employee retention credit claimed on Form(s) 943 for your farming business employees.
Caution: If you provided taxable fringe benefits to your employees, such as personal use of a car, do not include in farm labor the amounts you depreciated or deducted elsewhere.
