The Colorado DR 1191 form is a crucial document for businesses looking to take advantage of sales tax exemptions on machinery and machine tools used in manufacturing. This form serves as a certification that the purchaser is entitled to the exemption, provided that the machinery is used directly and predominantly to manufacture tangible personal property for sale or profit within the state. To qualify, the equipment must meet specific criteria, such as being capitalized, having a useful life of one year or more, and being part of a purchase order totaling over $500. Additionally, businesses located in designated enterprise zones can benefit from expanded exemptions, allowing for even greater savings on purchases. The form requires essential information, including the seller's and purchaser's Colorado Sales Tax Account Numbers, the date and amount of purchase, and a description of the machinery. It is important for purchasers to submit copies of the completed form to both the seller and the Colorado Department of Revenue, while also retaining a copy for their records. Understanding the nuances of the DR 1191 form can significantly impact a business's tax obligations and overall financial strategy.
