The Colorado Department of Revenue has finalized the adjusted rates for the state’s unique retail delivery fee, effective from July 1, 2026, through June 30, 2027. For this period, the total fee has been set at $0.31 per sale, a figure that represents the culmination of six distinct environmental and infrastructure assessments. This fee, which first entered the regulatory landscape in 2022, remains a critical component of Colorado’s strategy to fund transportation projects and mitigate the environmental impact of the burgeoning delivery economy. As the state continues to transition toward sustainable infrastructure, both domestic and out-of-state retailers must navigate a complex set of reporting requirements and exemption thresholds to remain compliant with Colorado law.
The retail delivery fee is not a traditional sales tax, though it is collected and remitted in a similar fashion. It applies to every retail sale of tangible personal property delivered by a motor vehicle to a location within Colorado, provided that at least one item in the order is subject to the state’s sales or use tax. Even if a delivery consists of multiple packages or shipments, it is legally defined as a single "retail delivery" for the purposes of the fee, provided the items were purchased in a single transaction.
Detailed Breakdown of the 2026-2027 Fee Structure
The $0.31 total fee is an aggregate of six individual charges mandated by Senate Bill 21-260, the landmark transportation funding legislation passed in 2021. For the fiscal year beginning July 2026, the specific allocations are as follows:
- Community Access Retail Delivery Fee: $0.0792 — This portion is directed toward the Community Access Enterprise, which supports the electrification of the transportation system, including the installation of electric vehicle (EV) charging stations in communities across the state.
- Clean Fleet Retail Delivery Fee: $0.0609 — These funds are managed by the Clean Fleet Enterprise to incentivize the transition of commercial delivery fleets to zero-emission vehicles.
- Clean Transit Retail Delivery Fee: $0.0344 — This allocation supports the Clean Transit Enterprise, focusing on reducing emissions in public transit through the adoption of electric buses and related infrastructure.
- General Retail Delivery Fee: $0.0965 — This is the largest single component and is directed toward the Highway Users Tax Fund for general road maintenance and safety improvements.
- Bridge and Tunnel Retail Delivery Fee: $0.0310 — Managed by the Statewide Bridge and Tunnel Enterprise, these funds are earmarked for the repair and replacement of Colorado’s aging bridge infrastructure.
- Air Pollution Mitigation Retail Delivery Fee: $0.0310 — This portion funds projects designed to offset the environmental impact of increased delivery traffic, particularly in areas disproportionately affected by tailpipe emissions.
The incremental nature of these fees reflects a broader legislative intent to ensure that those utilizing the state’s road infrastructure for commercial gain contribute directly to its upkeep and modernization.
Chronology of the Colorado Retail Delivery Fee
The implementation of the retail delivery fee has been a multi-year process characterized by legislative adjustments and administrative scaling.
- June 2021: Governor Jared Polis signs Senate Bill 21-260 into law. The bill was designed to generate nearly $5.4 billion over a decade for transportation projects without relying solely on traditional gas taxes, which have seen diminishing returns due to fuel efficiency and the rise of electric vehicles.
- July 1, 2022: The fee officially goes into effect at an initial rate of $0.27 per delivery. All retailers with active Colorado sales tax accounts were automatically registered for a retail delivery fee account.
- May 4, 2023: In response to feedback from the business community regarding the administrative burden on small enterprises, Governor Polis signs Senate Bill 23-143. This legislation introduced a critical exemption for small businesses.
- July 2023 – July 2025: The fee underwent annual adjustments based on the Consumer Price Index (CPI), rising incrementally from $0.27 to the current 2026 rate of $0.31.
- July 1, 2026: The new $0.31 rate takes effect, marking four years of the program’s operation.
Small Business Exemptions and Thresholds
One of the most significant developments in the fee’s history is the exemption for small-scale retailers. Under current Colorado law, a business is exempt from collecting and remitting the retail delivery fee if it meets either of the following criteria:
- The business is new (established within the current calendar year).
- The business had less than $500,000 in total retail sales in the previous calendar year.
The $500,000 threshold is calculated based on the retailer’s total sales, not just those delivered into Colorado. This ensures that only established, high-volume businesses are tasked with the administrative overhead of the fee. For out-of-state sellers, this threshold aligns with the broader "economic nexus" standards used in many states to determine tax obligations, although the $500,000 figure is higher than the typical $100,000 nexus threshold seen in other jurisdictions.
If a retailer exceeds the $500,000 sales threshold in a given year, they must begin collecting the fee on the first day of the fourth month after the end of that year. For example, a business that surpassed $500,000 in sales during the 2025 calendar year would be required to start collecting and remitting the fee on April 1, 2026.
Compliance and Reporting Requirements
For businesses that do not qualify for the small business exemption, the Colorado Department of Revenue (CDOR) has established specific protocols for reporting and payment. The fee must be reported on Form DR 1786. While the retail delivery fee is legally distinct from sales tax, the filing frequency for the fee matches the retailer’s sales tax filing schedule (monthly, quarterly, or annually).
Unlike local sales taxes, which vary by municipality and county, the retail delivery fee is a uniform statewide charge. This means retailers do not need to track different rates based on the specific delivery address within Colorado; the $0.31 applies universally to any delivery in the state.
A critical point for retailers to note is the handling of non-taxable sales. If an entire order is exempt from sales tax—such as a wholesale purchase for resale or a sale to a tax-exempt non-profit—the retail delivery fee does not apply. However, if a single item in a multi-item order is taxable, the entire delivery is subject to the $0.31 fee.
Marketplace facilitators, such as Amazon or eBay, are responsible for collecting and remitting the fee for sales made through their platforms. Individual sellers who operate exclusively through such marketplaces generally do not need to register for a separate retail delivery fee account, as the facilitator handles the compliance at the point of sale.
Administrative Nuances for Remote Sellers
Out-of-state retailers have expressed concern regarding the "automatic registration" process implemented by the CDOR. When the fee was launched in 2022, the state automatically opened retail delivery fee accounts for every business with an active Colorado sales tax permit.
For businesses that do not make deliveries into Colorado—such as those that only sell digital products or those that utilize "buy online, pick up in store" (BOPIS) models—these accounts can remain dormant. The CDOR has clarified that if a retailer makes no qualifying deliveries, they should not file a "zero return." Filing a zero return will keep the account active, whereas remaining inactive will eventually lead the state to close the account automatically. This is a rare instance where inaction is the prescribed administrative path for businesses without a filing obligation.
Broader Economic and Environmental Implications
The Colorado retail delivery fee is a pioneering model that other states are closely watching. As the United States moves toward a more digital economy, the volume of home deliveries has increased exponentially, leading to higher wear and tear on roads and increased carbon emissions from "last-mile" delivery vehicles.
Supporters of the fee argue that it is a necessary evolution of the "user-pays" principle. Historically, road maintenance was funded by gasoline taxes. However, with the rise of fuel-efficient vehicles and EVs, gas tax revenue has plateaued or declined. The retail delivery fee shifts some of that financial responsibility onto the delivery infrastructure that utilizes those roads most intensively.
Environmental advocates have praised the fee for its targeted reinvestment. By earmarking funds for "Clean Fleet" and "Clean Transit" initiatives, Colorado is directly tying the costs of delivery-based commerce to the solutions for its environmental impact. The 2026-2027 allocations show a continued commitment to this model, with over half of the $0.31 fee going toward air pollution mitigation and green transportation technology.
However, business advocacy groups, such as the National Federation of Independent Business (NFIB), have previously raised concerns about the "nuisance" nature of the fee. Critics argue that for many small-to-mid-sized businesses, the cost of updating point-of-sale software to accommodate a flat $0.31 fee outweighs the revenue generated. The 2023 small business exemption was a direct response to these concerns, significantly reducing the number of businesses required to participate while still capturing the vast majority of delivery volume through larger retailers and marketplaces.
Future Outlook
As the July 1, 2026, implementation date approaches, retailers are advised to update their billing systems to reflect the $0.31 rate. Software providers and tax automation services are increasingly integrating these specific state-level fees into their platforms, though some legacy systems may still require manual adjustments.
The success of Colorado’s program has already inspired similar legislation elsewhere. Minnesota, for instance, implemented its own retail delivery fee on July 1, 2024, signaling that this "delivery tax" model may become a standard feature of state revenue strategies in the coming decade. For businesses operating nationally, the Colorado experience serves as a blueprint for the type of environmental and infrastructure-focused compliance that is likely to expand across the United States.
Retailers seeking more information or specific forms are encouraged to consult the Colorado Department of Revenue’s official guidance. Staying ahead of these annual adjustments is essential for maintaining compliance and ensuring that the costs of doing business in the Centennial State are accurately accounted for.
