You can generally deduct the ordinary and necessary cost of insurance for your farm business as a business expense.
This includes premiums you pay for the following types of insurance.
• Fire, storm, crop, theft, liability, and other insurance on farm business assets.
• Health and accident insurance on your farm employees.
• Workers' compensation insurance set by state law that covers any claims for job-related bodily injuries or diseases suffered by employees on your farm, regardless of fault.
• Business interruption insurance.
• State unemployment insurance on your farm employees (deductible as taxes if they are considered taxes under state law).
