Since Neora Inventors, LLC is located in Missouri, we are required to collect sales tax for merchandise that is shipped to a Missouri address. However, some Missouri Farmers are exempt from sales tax on 'farm equipment and machinery'. If you purchase our products to be used solely for the production of farm goods that will ultimately be sold at retail, please send us an email at email@example.com and provide your order number, the business name of your farm, and a statement of your exemption from sales tax. We will send you a form (Form 149) that you can return to us to receive a refund for sales tax that you paid and for which you qualify for exemption. To find out whether or not you qualify for the exemption, you can google "missouri farm sales tax exemption".
