Form MC-1 General Information What is the medical cannabis cultivation privilege tax? “Medical cannabis cultivation privilege tax” is a tax that you (a medical cannabis cultivator) must remit for the medical cannabis sold. Who must file Form MC-1? You must file Form MC-1, Medical Cannabis Cultivation Privilege Tax Return, if you are a medical cannabis cultivation center. Do not file form MC-1 to report Adult Use Cannabis Cultivation Privilege Tax sold. These sales must be reported on Form CC-1, Adult Use Cannabis Cultivation Privilege Tax Return. You must attach Schedule MC-2, Medical Cannabis Sales, to your MC-1 return to identify each cultivation center from which you made sales of medical cannabis during the reporting period. Note: Medical cannabis dispensing organizations must report sales of medical cannabis on Form CD-1, Cannabis Dispensary Tax Return. Dispensaries that only sell medical cannabis will skip Step 2 when completing Form CD-1. Form ST-1, Sales and Use Tax and E911 Surcharge Return is still required to report sales of non-cannabis products. Receipts from cannabis sales should be taken as a deduction on Schedule A of Form ST-1. Who must file Schedule MC-2? If you have one business, but sell medical cannabis from more than one cultivation center, you must complete Schedule MC-2 to report sales from each cultivation center. You will need to complete Schedule MC-2 before completing Form MC-1. See Schedule MC-2 instructions. What sales are subject to the medical cannabis cultivation privilege tax? Tax is due on medical cannabis sold by a cultivation center. Medical cannabis includes both bulk medical cannabis and medical cannabis infused products. Bulk medical cannabis is dried cannabis • in its physical form to smoke; • in its physical form to vaporize; and • not infused or combined with another product for​ medicinal use. Medical cannabis infused product is a product containing cannabis or a cannabis concentrate, including • capsules; • food and beverage products prepared for consumption; • cooking oils; • tinctures or tonics, such as sprays or drops; • topicals, such as ointments, balms, oils, lotions, gels, or patches; • bath salts or oils; MC-1-Instructions (R-09/20) • aromatherapy sprays or essences; • concentrates, extractions, oils, or wax for use with a vaporizer; and • hash and concentrates, including ice wax, bubble hash, oil, wax, budder, pie crust, taffy, shatter, nectar, caviar, and kief. See 86 Illinois Administrative Code Part 429 for more information about medical cannabis products. How do I calculate the medical cannabis cultivation privilege tax? Tax is calculated at a rate of 7 percent (.07) of the sales price per ounce of medical cannabis. Tax on a package of medical cannabis is based on the total weight in ounces of medical cannabis as shown on the label required by 8 Illinois Administrative Code Section 1000.420. The sales price is determined without any deduction on account of the cost of property sold, the cost of materials used, labor or service cost, or any other expense whatsoever. See 86 Illinois Administrative Code Section 429.110 for rules regarding the treatment of transportation and delivery charges. The tax is computed on the sales price of the medical cannabis sold after the application of any applicable discounts. There is no cultivation privilege tax on free samples of medical cannabis given to a dispensing organization by a cultivation center. However, a cultivation center will incur Use Tax liability on the cost price of any free samples of medical cannabis given to dispensing organizations. See 86 Illinois Administrative Code Section 150.305(c). When must I file Form MC-1? You must file this return, along with any payment you owe, on or before the 20th day of the month following the end of the reporting period. Note: If the due date falls on a weekend or holiday, your return and payment are due the next business day. How can I file and pay electronically?

About the Corporate Income Tax
The IRS and most states require corporations to file an income tax return, with the exact filing requirements depending on the type of company.
Sole proprietorships or disregarded entities like LLCs are filed on Schedule C (or the state equivalent) of the owner's personal income tax return, flow-through entities like S Corporations or Partnerships are generally required to file an informational return equivilent to the IRS Form 1120S or Form 1065, and full corporations must file the equivalent of federal Form 1120 (and, unlike flow-through corporations, are often subject to a corporate tax liability).
Additional forms are available for a wide variety of specific entities and transactions including fiduciaries, nonprofits, and companies involved in other specific types of business.
