Colorado was one of the first states to legalize recreational cannabis in 2012, and its cannabis tax system has served as a model — and cautionary tale — for other states. The state imposes a ~15% excise tax on wholesale transfers from cultivators to retailers, a ~15% special sales tax on retail cannabis, and the standard state sales tax applies as well. Since legalization, Colorado has collected over approximately ~$2.5 billion in total cannabis tax revenue, funding education, public health, and local government programs. However, the maturing market has seen declining wholesale prices and flattening tax revenue in recent years.
Colorado Cannabis Tax Rates (2026)

Total Effective Tax Rate by Location (Estimated, Recreational)
| Location | Excise | Special Sales | General Sales | Local | Total Estimated |
|---|---|---|---|---|---|
| Denver | ~15% | ~15% | ~2.9% | ~7.65% | ~40.5% |

| Aurora | ~15% | ~15% | ~2.9% | ~6.5% | ~39.4% |
Medical cannabis is exempt from the ~15% special sales tax but is still subject to the ~2.9% state general sales tax and applicable local taxes.
How Colorado Cannabis Tax Works
Excise Tax (Wholesale Level)
The ~15% state excise tax is imposed on the first transfer or sale of unprocessed retail marijuana by a cultivation facility. The tax is calculated on the average market rate (AMR) of cannabis, which the Colorado Department of Revenue determines quarterly based on market data. For 2026, the projected AMR for flower is approximately ~$600 to ~$800 per pound, significantly lower than the approximately ~$1,800 to ~$2,000 per pound seen in the early years of legalization. This price decline has directly reduced excise tax revenue despite relatively stable sales volumes.
Special Sales Tax (Retail Level)
The ~15% special sales tax applies to all retail (recreational) cannabis sales at the point of sale. This tax was approved by Colorado voters through Proposition AA in 2013 and is collected by retailers and remitted to the Department of Revenue. The special sales tax is calculated on the retail price before general sales tax.
General Sales Tax and Local Taxes
Colorado’s ~2.9% general state sales tax applies to recreational cannabis in addition to the special sales tax. Local governments (cities and counties) may impose their own sales taxes, which can range from approximately ~1% to over ~8%. Denver’s combined local taxes of approximately ~7.65% push the total effective tax rate above approximately ~40% in the city.
Revenue Allocation
Colorado allocates cannabis tax revenue to multiple programs:
- BEST Fund (Building Excellent Schools Today): Receives the first approximately ~$40 million of excise tax revenue annually for school construction
- Public School Fund: Receives excise tax revenue above the ~$40 million threshold
- General Fund: Receives ~10% of special sales tax revenue
- State Public School Fund: Receives ~90% of special sales tax revenue
- Local governments: Retain local cannabis tax revenue for local priorities (public safety, infrastructure, etc.)
Since legalization, Colorado has allocated over approximately ~$700 million to education programs from cannabis tax revenue.
Comparison to Other Cannabis-Legal States
| State | Combined Excise Rate | Special Sales Tax | Total Estimated Rate |
|---|---|---|---|
| Colorado | ~15% (wholesale) | ~15% (retail) | ~30%—~40%+ |
| California | ~15% (retail) | None | ~25%—~40% |
| Washington | ~37% (retail) | None | ~37% |
| Oregon | ~17% (retail) | None | ~17%—~20% |
| Illinois | ~7%—~25% (THC-based) | ~6.25%+ sales | ~30%—~45% |
Colorado’s dual-tax structure (excise plus special sales) produces total rates comparable to California’s but higher than Oregon’s simpler single-tax model.
Tips for Cannabis Business Operators
- Track the Average Market Rate quarterly. The AMR directly determines your excise tax liability. Budget based on the most recent published rate.
- Separate recreational and medical sales. Medical cannabis is exempt from the ~15% special sales tax, so accurate categorization reduces the tax burden for qualifying patients.
- Budget for total effective rates of approximately ~30% to ~40%+. The layered tax structure means a significant portion of the retail price goes to taxes, affecting pricing strategy.
- File monthly returns. Colorado requires monthly filing of cannabis excise and sales tax returns. Late filing incurs penalties of approximately ~10% of the unpaid tax plus approximately ~1% per month interest.
- Monitor local tax rates. Local cannabis taxes can change with municipal elections. Verify rates annually for each jurisdiction where you operate.
- Plan for IRC Section 280E. Federal law prohibits deductions for cannabis-related business expenses, significantly increasing the effective federal income tax rate for cannabis operators.
- Stay current on regulatory changes. Colorado’s Marijuana Enforcement Division regularly updates licensing, testing, and compliance requirements that affect operations and costs.
