You can generally write off a portion of qualifying food and beverage costs. A couple factors are required to be eligible for the deduction: The expense must be a necessary part of carrying on your business, it can't be too lavish, and the business owner or an employee must be present. You can also deduct a portion of the cost of providing meals to employees. Meals provided at office parties and other outside work gatherings are also deductible. Be sure to keep documentation to outline each expense, including the date and place of the meal, and the business relationship of the person you dined with. Save your receipts!
