What is the Connecticut cannabis tax rate, and how does the CT cannabis tax calculator work?
The Connecticut cannabis tax rate on adult-use sales to buyers 21 and older is a flat 10.75% statewide cannabis tax from October 1, 2026, plus the 6.35% sales tax and a 3.0% municipal cannabis tax, per DRS. The CT cannabis tax calculator applies the sales tax, the municipal cannabis tax and the statewide cannabis tax rates to a price you enter.
Three taxes stack on one cannabis sale
When we ring up an adult-use sale, three separate taxes go on top of the sale price. The Department of Revenue Services (DRS) lists all three on its cannabis tax page.
- State sales and use tax, 6.35%. It applies to each cannabis sale that carries the statewide cannabis tax.
- Municipal cannabis tax, 3.0%. It is figured on the gross receipts from cannabis sales, per DRS.
- Statewide cannabis tax, 10.75%. A flat 10.75% of gross receipts from adult-use cannabis sales, in effect from October 1, 2026.
Per the DRS rates above, the 6.35% sales tax, the 3.0% municipal tax and the 10.75% statewide tax are each a percentage of the sale price.
The other state rules that apply to adult-use buyers are in our guide to Connecticut cannabis laws in 2026.
A $22.00 shelf price, step by step
DRS works through a $22.00 sale on its cannabis tax page. Here is that example, one line at a time.
- Start with the sale price: $22.00.
- Add the 6.35% sales tax: $1.40.
- Add the 3.0% municipal cannabis tax, per DRS: $0.66.
- Add the 10.75% statewide cannabis tax: $2.37.
- Pay the total: $26.43.
Each of the three tax lines is figured on the $22.00 sale itself, not on a subtotal that already includes another tax.

The old per-milligram system is history
Before October 1, 2026, the statewide cannabis tax was based on milligrams of THC, not on price. The old rates, listed in chapter 214c of the General Statutes, were set in cents per milligram of total THC, with a separate rate for each of these:
- Plant material: its own rate per milligram of total THC
- Edible products: its own rate per milligram of total THC
- Other cannabis: its own rate per milligram of total THC
Under that schedule, the tax on an item depended on its category and how many milligrams of total THC it held, so two items at the same price could carry different tax.
Since October 1, 2026, the statewide tax is a flat percentage of the sale, so the price sets the amount. Any article, receipt or calculator that still works in cents per milligram is describing the old system.
Estimate your own total with the calculator
The calculator on this page estimates a total from the shelf price you enter.
Once you know roughly what a cart will come to, order from our Derby store, which takes scheduled delivery orders through its live menu, or plan on in-store pickup at our Hartford store.
Product prices live on the menu and current offers on our deals page, since both change more often than tax law does.
Who pays the same rate and who is exempt
Where you live does not change the tax. The Department of Consumer Protection (DCP) says in its answer for out-of-state buyers that non-residents are charged the same state and local taxes as Connecticut residents for adult-use cannabis.
Medical program sales are taxed differently. Under chapter 214c, the state cannabis tax and the municipal cannabis tax do not apply to the sale of cannabis for palliative use, and under chapter 219 those sales are also exempt from sales tax. CT Mirror reported on January 28, 2026 that Connecticut patients registered under the state's medical marijuana program receive tax-free cannabis products.
A hybrid retailer may sell medical marijuana products to qualifying patients and caregivers as well as adult-use cannabis. Both our stores are licensed adult-use cannabis retailers, not hybrid retailers.
Questions shoppers ask about Connecticut cannabis tax
Can I buy if I live in another state?
Yes. DCP says any adult 21 or older with a valid government-issued photo ID may buy from licensed adult-use retailers or hybrid retailers regardless of state of residence. DCP also says non-residents are charged the same state and local taxes as Connecticut residents for adult-use cannabis, so where you live does not change the tax.
Is there a daily purchase limit?
Yes. Under state law, a retailer or hybrid retailer may not knowingly sell a consumer more than one ounce of cannabis or the equivalent in products per day. The limit counts per consumer per day, so it applies to every sale, whatever the tax lines add up to.
Do medical patients pay these taxes?
Not on medical cannabis. DCP says medical cannabis is medication and not subject to sales taxes, and the state cannabis tax and the municipal cannabis tax do not apply to the sale of cannabis for palliative use. The three tax lines on this page are for adult-use sales to buyers 21 and older.
What taxes get added to a cannabis sale at the register?
Per DRS, the register adds three lines: the 6.35% state sales and use tax, the 3.0% municipal cannabis tax and, since October 1, 2026, a flat 10.75% statewide cannabis tax on adult-use sales. Each line is a percentage of the sale, and adult-use buyers must be 21 or older.
Did the way the statewide cannabis tax is figured change?
Yes. Before October 1, 2026, the statewide cannabis tax was based on milligrams of THC. Per DRS, since that date it is a flat 10.75% of gross receipts from adult-use cannabis sales to adults 21 and older. Statute text printed in chapter 214c still lists cents-per-milligram rates, which DRS treats as superseded.
How do the three taxes add up on a sample sale?
DRS works through a $22.00 sale with $1.40 in sales tax, $0.66 in municipal tax and $2.37 in statewide cannabis tax, for a $26.43 total. The calculator on this page applies the sales tax, the municipal cannabis tax and the statewide cannabis tax rates to a shelf price you enter.
