Part 2: Taxable PropertySales made without tax collectionPurchases made outside of ColoradoIn general, any retailer who sells tangible personalproperty in Colorado is required to collect theapplicable state and state-administered local salestaxes at the time of the sale. However, the consumermust pay use tax directly to the Department if theseller did not collect the applicable tax for any reason.Some of the more common reasons that a seller mightnot have collected the applicable sales tax arediscussed in the following sections.If a person, business, or other legal entity purchasestaxable property outside of Colorado and brings thatproperty into Colorado for use in this state, theproperty will be subject to consumer use tax. However,if the purchaser paid sales tax to the other state at thetime of purchase, the purchaser will be allowed acredit toward the use tax due in the amount of thesales tax paid. Please see Part 3 of this publication foradditional information about the credit allowed forsales taxes paid to another state.Purchases made over the internetSales between private partiesTangible personal property purchased over the internetand delivered into Colorado is not exempt from taxationsimply because it was purchased online. However, if theseller does not have a store, warehouse, or otherphysical location in Colorado and makes only minimalsales into Colorado, the seller might not be required tocollect the applicable sales tax at the time of thepurchase. If a person, business, or other legal entitypurchases tangible personal property online for use inColorado, and pays no sales or use tax to the seller atthe time of purchase, that purchaser will owe use tax onthe purchased property.If tangible personal property is purchased from aprivate party who does not have a sales tax license andtherefore does not collect sales tax, the purchasermust pay the applicable consumer use tax directly tothe Department.Items removed from inventoryA wholesaler or retailer may purchase tangible personalproperty, including ingredients and component parts,for resale without paying sales tax at the time ofpurchase. However, if the wholesaler or retailerwithdraws an item purchased tax-free from inventoryfor the retailer’s own use, the retailer will owe use taxon that item. Use tax applies regardless of whether thewholesaler or retailer uses the withdrawn item for itscustomary purpose, for testing, for quality control, forresearch and development purposes, or for any otherpurpose.An out-of-state retailer who sells taxable property intoColorado, but does not collect Colorado tax, must: present the purchaser with a notice at the time ofthe sale advising them of their obligation to payconsumer use tax directly to the Department; send the purchaser an annual summary in Januarylisting the purchases they made during the prioryear; and report to the Department the total dollar amount ofthe purchases each purchaser in Colorado made.The annual summary will assist purchasers in reportingand paying consumer use tax.

Part 3: Calculating Consumer Use TaxColorado use tax is calculated at the same 2.9% rate asthe state sales tax. Some cities, counties, and specialdistricts in Colorado also impose a use tax. Please seeDepartment publication DR 1002, Colorado Sales/UseTax Rates for information about local use tax rates andapplicability in Colorado. Additional information aboutthe remittance of local use taxes can be found in Part 4of this publication.Exchanged propertyUnder certain conditions, the fair market value oftangible personal property exchanged by the purchaseras part of a sale is excluded from the taxable purchaseprice. The fair market value of the tangible personalproperty exchanged by the purchaser is excluded fromthe taxable purchase price, if either:This Part 3 provides information about the calculationof Colorado use tax. such exchanged property is to be sold thereafter inthe usual course of the retailer's business; or such exchanged property is a vehicle and isexchanged for another vehicle and both vehiclesare subject to licensing, registration, orcertification in Colorado, including, but notlimited to, vehicles operated upon craft, and aircraft.Purchase priceIn general, Colorado use tax is calculated on the fullpurchase price of the taxable item. The taxablepurchase price includes the full amount paid, orpromised to be paid, by the buyer at the time ofpurchase of the property, excluding only any directfederal tax and any state and local sales tax imposedon the sale. The taxable purchase price includes thegross value of all material, labor, and service, and theprofit thereon included in the price charged to the useror consumer.If the purchaser transfers intangible property or performsservices in exchange for tangible personal property, thefair market value of the intangible property or service isnot excluded from the purchase price.Gifted propertyCouponsIn the case of a bona fide gift of tangible personalproperty, the recipient of the gift owes no use tax on theitems since they did not purchase the item at retail.Instead, the giver must pay sales tax when purchasing theitem or, if no sales tax was collected by the seller at thetime of the sale, the giver must pay use tax based on thepurchase price of the item.Whether a coupon reduces the taxable purchase pricefor use tax purposes depends on whether the coupon isa manufacturer's coupon or a store coupon.In the case of a manufacturer's coupon, themanufacturer compensates the retailer for reducingthe price the purchaser pays. Because the retailer isreimbursed by the manufacturer for the amount of thereduction, use tax applies to the full selling pricebefore the deduction for the manufacturer's coupon.A store coupon is issued by the retailer for a reductionin the sales price when the coupon is presented to theretailer by the customer. Because there is noreimbursement to the retailer for such reduction, thetaxable purchase price is the reduced price that thepurchaser pays.7Revised June 2021

Part 3: Calculating Consumer Use TaxAssociated service chargesAdditional resourcesWith certain exceptions discussed below, the taxablepurchase price includes any service charges associatedwith the sale of tangible personal property, such ascharges for installation or delivery. Associated servicecharges are included in the taxable purchase price unlessboth the service is separable from the sale of the propertyand the service charge is separately stated from the priceof the property sold on the invoice or receipt.The following is a list of statutes, regulations, forms,and guidance pertaining to the calculation of Coloradouse tax. This list is not, and is not intended to be, anexhaustive list of authorities that govern the taxtreatment of every situation. Individuals and businesseswith specific questions should consult their tax advisors.Statutes and regulationsAn associated service is separable from the sale of theproperty if the service is performed after the taxableproperty is offered for sale and the purchaser has theoption not to purchase the associated service. Forexample, if delivery is optional and the purchaser mayelect to pick up the property at the seller’s store,without paying the delivery charge, the delivery chargeis separable. § 24-60-1301, C.R.S. Execution of compact. § 39-26-102, C.R.S. Definitions. § 39-26-201, C.R.S. Definitions. § 39-26-202, C.R.S. Authorization of tax. § 39-26-713, C.R.S. Tangible personal property.An associated service charge is separately stated if itappears as a distinct line item on a written salescontract, retailer’s invoice, or other written documentissued in connection with the sale, apart from the priceof the property sold. However, the statement of acharge as a separate line item does not necessarilyindicate that the charge is also separable. Rule 39-26-102(7)(a). Rule 39-26-102(10). Rule 39-26-102(12). Rule 39-26-104-3.
