Form CD-1-X Instructions

Who must file Form CD-1-X?

You must file Form CD-1-X if you filed Form CD-1, Cannabis Dispensary Tax Return, and you need to

• correct your return, either to pay more tax or to request a credit for overpaid tax;
• respond to a bill or notice; or
• make corrections to line items but not change the amount of tax due.

You must file a separate Form CD-1-X for each filing period you are amending. You cannot file a single CD-1-X to amend multiple filing periods.

Note: Form CD-1-X is only used to amend cannabis sales reported on Form CD-1. If you are filing the CD-1-X to amend your total receipts of cannabis sold, you must also file Form ST-1-X, Amended Sales and Use Tax and E911 Surcharge Return, to amend the corresponding Form ST-1.

Note: If you received a notice from us that your original return is unprocessable, we cannot process an amended return until you respond to the notice. Also, if you are requesting a credit, you will not be able to use it until we notify you that your credit has been approved.

What must I attach to this return?

If you are a business with more than one dispensary, you must attach Schedule CD-2, Sales and Use Tax Multiple Site Form for Cannabis Dispensaries, to calculate the Sales and Use Tax due on sales of adult use and medical cannabis from each dispensing site for your business during the filing period.

If you are a business with more than one dispensary and make sales of adult use cannabis, you must attach Schedule CD-3, Cannabis Purchaser Excise Tax Multiple Site Form for Cannabis Dispensaries, to report sales of adult use cannabis subject to Cannabis Purchaser Excise Tax from each dispensing site for your business during the filing period.

What if I do not attach all applicable schedules to this return?

We will consider your amended return unprocessable and will issue a notice to you if you do not attach all required supporting schedules.

What is the deadline for filing this form?

The period for which you can claim a credit for an overpayment of Cannabis Purchaser Excise Tax or Sales and Use Tax due on cannabis depends on when you file your Form CD-1-X. If you file this amended return between January 1 and June 30 of this year, you may file a claim for credit for the amounts you overpaid during the current year and previous 36 months. Beginning July 1, you may file a claim for the amounts you overpaid during the current year and previous 30 months.

For any period included in a claim for credit or refund for which the statute of limitations for issuing a notice of tax liability under the Retailers’ Occupation Tax Act or the Cannabis Purchaser Excise Tax Act will expire less than six months after the date a taxpayer files the claim for credit or refund, the statute of limitations for issuing a notice of tax liability is automatically extended for six months from the date it would have otherwise expired.

Note: There is no deadline for making additional payments; however, the longer you wait to pay, the more interest and, when applicable, penalty you will owe.

Can I file Form CD-1-X and pay the tax due electronically?

Illinois law requires Form CD-1-X to be filed electronically and the tax to be paid electronically. You must use MyTax Illinois at mytax.illinois.gov to file your Form CD-1-X and pay any tax due. To request a waiver of the electronic payment mandate, complete Form IL-900-EW, Electronic Waiver Request, which is available from the Illinois Department of Revenue by request at 217 782-7897, 1 800 732-8866, or 217 782-3336. If granted and unless renewed, this waiver shall not exceed two years.

What if I fail to file or pay the amount I owe?

You owe a late-filing penalty if you do not file a processable return by the due date, a late-payment penalty if you do not pay the amount you owe by the payment’s due date, a bad check penalty if your remittance is not honored by your financial institution, and a cost of collection fee if you do not pay the amount you owe within 30 days of the date printed on a bill. Interest is calculated on tax from the day the payment was due through the date you pay the liability. We will bill you for penalty and interest. For more information, see Publication 103, Penalty and Interest for Illinois Taxes, which is available on our website at tax.illinois.gov.

In addition, you will not be entitled to any discounts. See 35 ILCS 120/3 and 410 ILCS 705/65-30 for more information.
