This form is commonly used by businesses engaged in farm production and commercial horse boarding. The ST-125 demonstrates eligibility for a tax exemption on goods related to farming. It provides tax-exempt status for the purchase of qualifying items used in agricultural activities.

When You’d Use New York Form ST-125 (2021)

Form ST-125 is used when a business is engaged in farming or horse boarding operations. If you operate a commercial horse boarding operation, you can apply for a tax exemption for qualifying purchases. The form is necessary to ensure that you don’t pay sales tax on exempt items.

Farmers and boarding operations that qualify under New York’s agricultural use law will benefit from this form. Once completed, Form ST-125 enables businesses to purchase agricultural products without incurring sales tax. Using the form correctly can save significant amounts in tax costs.
