NH’s Lost Cannabis Revenue

Last verified: April 2026

The No-Income-No-Sales-Tax Backdrop

New Hampshire is one of nine U.S. states with no broad-based individual income tax and one of five with no general sales tax. Revenue comes from property taxes (uniformly high statewide), the Business Profits Tax, the Business Enterprise Tax, the Rooms and Meals Tax (8.5%), the Communications Services Tax, and a handful of fees and excise taxes including tobacco, alcohol, and gasoline.

The implication for cannabis tax debates: a NH cannabis excise tax (HB 186 proposed 8.5%) would create entirely additive revenue. In states like Massachusetts or Vermont, legalizing cannabis displaces some existing alcohol or tobacco purchases — and the sales-tax baseline already captures purchases. In NH, none of those offsets apply. Every dollar of taxed cannabis sale is a new dollar to the state.

Estimating the Cross-Border Outflow

Estimates from Massachusetts Cannabis Control Commission revenue data have suggested that 15-25% of MA adult-use revenue from northern Massachusetts dispensaries originates with New Hampshire consumers. The MA market totals over $1 billion annually statewide. Even on the most conservative assumption that 5-8% of total MA recreational sales (not just border-cluster sales) come from NH residents, that is $50-80 million per year in NH-resident spending, generating substantial MA tax revenue that NH receives none of.

Adding in NH spending at Maine and Vermont dispensaries:

• Massachusetts — cannabis tax revenue ~$200 million+ annually (combined excise and local). NH-resident contribution dominates the I-93 and US-3 corridor dispensaries per dispensary operator reports; NH plates dominate the parking lots at Tyngsborough and Methuen on weekends.
• Maine — cannabis tax revenue ~$30-40 million+ annually. NH-plate share is significant in the Kittery and Eliot dispensary cluster — six adult-use dispensaries in Kittery alone along Route 236 and Route 1.
• Vermont — cannabis tax revenue ~$20 million+ annually. NH-plate share is significant in the White River Junction (Five Seasons) and Brattleboro (Theory Wellness, Vermont Bud Barn) clusters.

Conservative bottom line: NH residents send tens of millions of dollars annually in retail spending to MA, ME, and VT — producing tax revenue that flows entirely to the destination states.

Sen. Donovan Fenton (D-Keene) estimated during 2026 testimony on HB 186 that New Hampshire would generate roughly $60 million in cannabis tax revenue over three years if the legalization framework had been enacted. The estimate reflected an 8.5% excise tax applied to a regulated retail market sized to capture the residents currently shopping in MA, ME, and VT.

Sen. Fenton’s $60 Million Number

Sen. Donovan Fenton (D-Keene), a 2025–2026 legalization sponsor in the Senate, estimated during 2026 testimony on HB 186 that roughly $60 million in NH revenue over three years would result if the bill became law. The number reflected an 8.5% excise tax applied to a regulated retail market sized to capture residents currently shopping in MA, ME, and VT. Critics argued the estimate was conservative; advocates argued it understated the longer-term tax base.

The Fenton number became the single most-cited figure in HB 186 floor debate. Senate Republicans — including Senate President Sharon Carson (R) — rejected the revenue argument as insufficient against youth-mental-health and traffic-safety concerns, and the bill was tabled 15-9 in April 2026.

Comparison: NH’s Sports-Betting Precedent

NH legalized sports betting in 2019 after observing revenue flowing to Massachusetts and other neighboring jurisdictions. The cannabis revenue argument has been deployed in NH House debates by analogy: the same dynamic of border-state revenue capture argues for a similar policy response on cannabis. Senate Republicans have rejected the analogy, on the grounds that cannabis raises different public-health concerns than sports betting.

The sports-betting model is mostly run through DraftKings under a state contract; cannabis legalization vehicles like HB 186 have ranged from full retail markets (HB 198, 2025) through state-franchise models (Sununu’s 2023 pivot, embedded in HB 1633) to no-commercial-market frameworks (HB 75, 2025). Each model has different revenue projections.

The Tax-Stamp Argument NH Doesn’t Have

Some prohibition states (Iowa’s Chapter 453B, several others) have tax-stamp laws requiring drug dealers to purchase stamps for marijuana — an obscure regulatory mechanism mostly used as an enhanced charge against trafficking convictions. NH has never enacted a tax-stamp law for marijuana. The 2017 decriminalization (HB 640) eliminated the practical relevance of the question for personal possession. NH’s revenue argument is therefore not about tax-stamp recovery; it is about future excise revenue from a regulated retail market.

What HB 186 Would Have Done

The 2026 lead bill, HB 186, would have:

• Imposed an 8.5% excise tax on regulated cannabis sales (matching the existing NH Rooms and Meals Tax rate).
• Created a Cannabis Commission and 15-member Cannabis Advisory Board to license retailers.
• Vacated past possession convictions.
• Added non-discrimination protections for cannabis consumers in medical care (including organ transplants), child custody, public benefits, and government employment.

Estimated revenue: ~$60 million over three years (Sen. Fenton). The bill passed the House 208-135 in January 2026, was deemed “inexpedient to legislate” 2-1 in Senate Judiciary in March 2026, and was tabled 15-9 by the full Senate in April 2026.

Why the Argument Hasn’t Worked

Three reasons cited by Senate opponents:

• Public-health framing — Senate Republicans, Gov. Ayotte, and New Futures argue the social costs (youth mental health, traffic safety, addiction services) outweigh tax revenue. Sen. Sharon Carson’s 2024 floor remarks emphasized this framing.
• Distrust of revenue projections — Some legislators argue revenue estimates from advocacy-aligned sources understate enforcement, regulation, and public-health costs.
• Cultural identity — The NH legislative tradition has been to fund the state through narrow taxes and high property taxes rather than broad new revenue sources, even when those new sources are popular. Cannabis tax revenue, in this framing, would be a structural change rather than a windfall.
