Cannabis tax rates are located on the Tax Rates and Due Dates webpage. Find the appropriate operation type and multiply the rate either by gross receipts percentage (retail and manufacturing) or by square feet (cultivation).
In general, taxes are due on the last business day of the month following the close of a quarter, unless the Tax Collector has informed you of a shorter filing period. In this case they are due on the last business day of the month after the close of the shorter period.
Operators with outdoor cultivation permits will only file a tax return in Quarter 2 and Quarter 3. The annual tax will be prorated evenly over those two quarters.
