Montana Cannabis Tax Structure
Montana levies a 20% state excise tax on recreational cannabis sales and 4% on medical. Counties can add a local option tax of up to 3%, and approximately 30 counties have done so. SB 74 (2025) revised the tax calculation to apply after discounts, providing a small benefit to consumers.
| Tax Type | Recreational | Medical |
|---|---|---|
| State excise tax | 20% | 4% |
| Local option tax | Up to 3% (~30 counties) | Up to 3% |
| Effective Total | 20–23% | 4–7% |
First $6M annually → HEART Fund (mental health). Then 20% to Fish, Wildlife & Parks (wildlife habitat), 4% each to state parks/trails/nongame. Cannabis tax directly funds conservation — unique nationally.
Revenue Over Time
| Year | Total Sales | Adult-Use Share | Est. Tax Revenue |
|---|---|---|---|
| 2022 | ~$304M | 60% | ~$45.7M |
| 2023 | ~$319M | Growing | ~$54.1M |
| 2024 | ~$324M | 88% | ~$57.4M |
| 2025 | ~$327M | 90% | ~$59.4M |
Cumulative: $1.27B in sales, $217M in tax revenue. 107% market capture (tourism from ID/WY/ND/SD). ~$18M/year funds conservation.
Revenue by the Numbers
Where the Money Goes
Montana's cannabis tax allocation is one of the most distinctive in the nation, with a significant portion going to conservation and public health:
| Allocation | Recipient | Est. Annual (2025) |
|---|---|---|
| First $6M | HEART Fund (mental health/addiction) | $6.0M |
| 20% of remainder | Fish, Wildlife & Parks | ~$10.7M |
| 4% of remainder | State Parks | ~$2.1M |
| 4% of remainder | Trails & Nongame Wildlife | ~$2.1M |
| Fixed | Veterans Services | $0.2M |
| Fixed | Crisis Training | $0.15M |
| 5% | CARD Administration | ~$2.7M |
| Remainder | General Fund | ~$35.5M |
Approximately $18 million per year flows to conservation (FWP, state parks, trails, nongame). This unique allocation was central to the I-190 campaign and is one of Montana's most distinctive cannabis policy features. Learn more on our Cannabis Funds Conservation page.
Medical vs. Recreational Tax Savings
The 16-percentage-point difference between recreational (20%) and medical (4%) tax rates creates a strong incentive to maintain a medical card. For a patient spending $200/month:
| Annual Spending | Recreational Tax (20%) | Medical Tax (4%) | Annual Savings |
|---|---|---|---|
| $1,200 | $240 | $48 | $192 |
| $2,400 | $480 | $96 | $384 |
| $3,600 | $720 | $144 | $576 |
This tax differential largely explains why Montana retains nearly 15,000 medical patients despite full recreational access.
The 107% Market Capture
Montana's cannabis market sells more than its 1.1 million residents would consume alone. Market analysts estimate a 107% capture rate, meaning Montana collects 7% more revenue than a residents-only market would produce. This surplus is driven by:
- 13.8 million annual tourists — visitors to Glacier, Yellowstone, and ski resorts
- Zero legal neighbors — Idaho, Wyoming, North Dakota, and South Dakota residents crossing into Montana
- Gateway town density — 15 dispensaries in Whitefish, 13 in Columbia Falls, catering to visitors
- Seasonal swing — 25% higher sales during summer tourist months
2025 Tax Reform: SB 74
SB 74 (2025) revised how excise tax is calculated, specifying that the tax applies after discounts rather than on the pre-discount price. This provides a modest consumer benefit and ensures tax fairness. HB 932 (2025) also adjusted the allocation percentages to direct approximately one-third of revenue to conservation.
License Fee Revenue
In addition to excise taxes, CARD collects annual license fees from all cannabis businesses:
| License Type | Tiers/Notes | Annual Fee Range |
|---|---|---|
| Cultivator | 12 tiers (Micro 250 sq ft to Tier 12 50K sq ft) | $1,000–$37,000 |
| Manufacturer | 3 tiers by volume | $5,000–$20,000 |
| Dispensary | Per location | $5,000 |
| Transporter | Renewed every 2 years | $10,000 |
| Testing Laboratory | Plus Testing Lab Endorsement | $5,000 |
| Combined-Use (Tribal) | 1 per tribe, single premises | $7,500 |
License moratorium through June 30, 2027 (SB 27). New applicants accepted starting July 1, 2027. Operational control must be a Montana resident (1+ year). ~1,000 licensed premises statewide.
