Connecticut adult-use cannabis carries three taxes at the register. Since October 1, 2026, the state cannabis tax is a flat 10.75% of gross receipts, replacing the old tax based on milligrams of THC. The 6.35% state sales tax and a 3% municipal cannabis tax also apply, for a combined rate of about 20%. Cannabis sold to registered medical patients is exempt from all three.
| Tax | Rate | Who pays and what it covers |
|---|---|---|
| Statewide cannabis tax | 10.75% | Gross receipts from adult-use sales by retailers, hybrid retailers, and micro-cultivators. Filed with DRS on myconneCT. |
| State sales tax | 6.35% | Adult-use retail sales. |
| Municipal cannabis tax | 3% | Adult-use retail sales. The money goes to the town where the sale happens. |
| Former THC-based tax | Ended Sept 30, 2026 | 0.625 cents per mg of THC for flower, 2.75 cents for edibles, and 0.9 cents for other products. Still used for earlier periods. |
| CT income and corporation tax | 280E decoupled | Since 2023, licensees can deduct expenses disallowed by federal 280E on Connecticut returns. |
On a $100 adult-use purchase, the three taxes add roughly $20. The flat rate makes pricing simpler than the THC-based tax, but POS settings, price lists, and cash flow models built on the old rates need updating. Our tax planning and compliance team can review your setup, and our cannabis tax rates by state guide shows how Connecticut compares.

Connecticut Cannabis Businesses Need Specialized Financial Guidance.
Connecticut legalized recreational cannabis on July 1, 2021, with retail sales beginning January 2023. The state has built a layered regulatory environment that operators must navigate, including the flat 10.75% cannabis tax that replaced the THC-based tax on October 1, 2026, municipal cannabis taxes, Connecticut Department of Revenue Services compliance requirements, and federal 280E limitations.
Connecticut is also one of a small number of states that has decoupled from federal Section 280E for state tax purposes, creating planning opportunities that operators in most other markets do not have. GreenGrowth CPAs helps Connecticut cannabis operators take full advantage of these state-specific benefits while maintaining federal compliance. For a broader view of our practice, see our cannabis CPA services.

How 280E and Connecticut Decoupling Affect Operators
Section 280E prevents adult-use cannabis businesses from deducting ordinary business expenses at the federal level because adult-use cannabis remains a Schedule I controlled substance. Medical cannabis sold under a state license moved to Schedule III effective April 28, 2026, so 280E no longer applies to that medical activity going forward. For Connecticut operators, the federal burden still applies fully, which makes COGS optimization and entity structure essential.
Importantly, Connecticut decoupled from federal 280E at the state level effective January 1, 2023. This means licensed CT cannabis businesses can deduct ordinary and necessary business expenses (rent, payroll, utilities) on their Connecticut state corporate or personal income tax returns, even though the federal disallowance continues. Capturing this benefit requires deliberate state-level tax planning that most national CPAs miss.
You May Need a Connecticut Cannabis CPA If:
- You are not capturing the full benefit of Connecticut's 280E decoupling
- Your pricing, POS settings, or cash flow models still use the old THC-based tax
- Your books do not clearly separate COGS from operating expenses
- You operate across multiple Connecticut locations or license types
- You need better cash flow planning around combined state and federal tax obligations

Connecticut Cannabis CPA FAQs
What taxes do cannabis businesses pay in Connecticut?
Connecticut cannabis operators pay three layers of tax on adult-use sales: a state excise tax, a 6.35% state sales tax, and a 3% municipal tax in participating cities and towns. Since October 1, 2026, the state cannabis tax is a flat 10.75% of gross receipts, replacing the earlier tax based on THC content. All cannabis taxes are filed monthly through DRS via myconneCT. Cannabis sold to registered medical patients is exempt from the cannabis tax, the municipal tax, and sales tax.
What does Connecticut's 280E decoupling mean for my business?
Effective January 1, 2023, Connecticut decoupled from federal 280E at the state level. Licensed CT cannabis businesses can deduct ordinary and necessary business expenses (rent, payroll, utilities, marketing, professional services) on their Connecticut state corporate or personal income tax returns, even though federal 280E still disallows those same deductions on the federal return. This is a meaningful CT-specific advantage that requires deliberate state tax planning to capture fully, and that operators in most other states do not have access to.
How does Section 280E impact cannabis businesses in Connecticut at the federal level?
At the federal level, Section 280E still prevents adult-use cannabis businesses from deducting ordinary business expenses because adult-use cannabis remains a Schedule I controlled substance. Medical cannabis sold under a state license moved to Schedule III effective April 28, 2026, so 280E no longer applies to that medical activity going forward. The primary federal strategy is maximizing deductible cost of goods sold through careful accounting and documentation. Connecticut's state-level decoupling helps offset some of the federal burden but does not eliminate it, so federal 280E planning remains essential.
What changed on October 1, 2026 with Connecticut's cannabis tax?
On October 1, 2026, Connecticut replaced its THC-based cannabis tax with a flat 10.75% tax on gross receipts from adult-use sales by retailers, hybrid retailers, and micro-cultivators, under Public Act 26-68. The 3% municipal tax and 6.35% sales tax still apply on top. Operators need POS settings, pricing, and cash flow models built on the new rate, and returns for periods before October 1 still use the old THC-based rates.
Can GreenGrowth CPAs help with Connecticut's social equity licensing requirements?

GreenGrowth CPAs understands Connecticut's social equity framework and can help qualifying businesses build the financial systems, reporting infrastructure, and compliance documentation needed to operate successfully under their license type, including tracking and reporting tied to social equity council requirements where applicable.

How much is CT cannabis tax?
CT cannabis tax adds about 20% to an adult-use purchase: the flat 10.75% statewide cannabis tax (in effect since October 1, 2026), the 6.35% state sales tax, and the 3% municipal cannabis tax. On a $100 purchase that is roughly $20. Before October 1, 2026, the statewide tax was based on milligrams of THC instead of price. Registered medical patients are exempt.
