The Colorado Department of Revenue (CO DOR) has adopted Special Rule 46 (hereafter, final rule) providing guidance on the sales and use tax treatment of lease transactions involving tangible personal property.¹ The final rule clarifies the taxability of lease arrangements, including distinctions between long-term and short-term leases, and addresses the treatment of related party leases, lessor acquisitions, subleases and sale-leaseback transactions.

Under the final rule, leases of tangible personal property are generally treated as retail sales and are subject to Colorado and state-administered local sales taxes, unless a specific exemption applies. The final rule is intended to provide consistency in the application of sales and use tax to lease structures and to address perceived areas of noncompliance. The final rule includes guidance for both long-term and short-term leases based on the duration of the arrangement. By statute, a long-term lease is defined as one exceeding 36 months, while a short-term lease is one with a term of 36 months or less. This distinction is important because it affects both the taxability of the lease payments, as well as the treatment of the lessor's acquisition of the underlying property.

For long-term leases, a lessor's purchase of property may qualify for an exemption from sales and use tax as a wholesale sale, if the primary purpose of acquiring the property is to lease it in an unaltered condition as part of the lessor's regular business activities. If, however, the lessor uses or intends to use the property, the exemption is not available, and tax is due on the purchase. The final rule further requires these determinations to be based on the substance of the transaction rather than its form.

The final rule also establishes additional requirements for short-term lease arrangements. In general, before purchasing property tax free for use in short-term leases, a lessor must obtain permission from the CO DOR to charge sales tax on lease payments rather than to pay tax upfront on the purchase of the leased property. If the lessor fails to obtain permission, the lessor may be required to pay sales or use tax on the purchase of the property and collect tax on lease payments made by the lessee, depending on the circumstances.

The final rule places particular emphasis on lease arrangements involving related parties. Transactions between related entities are subject to heightened scrutiny, and the rule provides that a lessor is presumed to have used the property if the lease is entered into without charge or at a price that is inconsistent with arm's-length standards. An arm's-length rental charge is defined as the amount that would be charged in a comparable transaction between unrelated parties under similar circumstances, considering factors such as the lease term, location and condition of the property.

Additionally, the final rule prevents a sale-leaseback transaction from being treated as a lease for sales tax purposes when the transaction is, in substance, a financing arrangement. In these cases, the tax-treatment determination is based on the underlying economic substance of the transaction rather than its legal form.

Implications

The final rule may have significant implications for taxpayers engaged in leasing activities, particularly those with related party lease arrangements or structured leasing transactions. Taxpayers should consider evaluating whether existing lease agreements (1) reflect arm's-length pricing and (2) have sufficient economic substance to support the intended tax treatment.

In addition, taxpayers that rely on wholesale exemption treatment for the acquisition of leased property should confirm that the property is not used by the lessor and that the leasing activity constitutes a bona fide business operation. Taxpayers involved in short-term leases should consider assessing whether appropriate approvals have been obtained to acquire property tax-free, as failure to do so may result in unexpected tax liabilities.

Given the final rule's emphasis on substance over form and heightened scrutiny of related party transactions, taxpayers may also face an increased risk of adjustments or recharacterization of lease arrangements. As a result, taxpayers may want to consider reviewing existing structures and documentation for compliance with the rule's guidance.
