  • 15% Statewide Excise Tax: Delaware cannabis retailers pay a 15% excise tax on retail sales (rounded up to the nearest cent).
  • Gross Receipts Tax (GRT): All cannabis businesses owe Delaware’s GRT — rates vary from 0.0945% to 0.7468% based on NAICS business classification.
  • No Local Add‑On Taxes: There are no municipal or county excise or sales taxes beyond the state GRT.
  • Medical Exemption: Medical cannabis sales to registered cardholders are exempt from the 15% excise tax but remain subject to GRT.
  • Decoupling from IRC § 280E: Delaware allows state-level deductions for ordinary and necessary business expenses, despite federal disallowance under § 280E.
  • Mandatory Filings: Timely, accurate monthly (or quarterly) filings for both excise tax and GRT are required. Penalties, interest, and potential license suspension apply for noncompliance.

1. Understanding Delaware’s Cannabis Tax Structure

1.1 Retail Marijuana Excise Tax

  • Rate: 15% of the retail sales price, rounded up to the nearest cent.
  • Applicability: All licensed recreational cannabis retailers statewide.
  • Medical Exemption: Retailers must verify a valid Delaware medical marijuana card at the point of sale to waive the excise tax; retain proof for each transaction.

1.2 Gross Receipts Tax (GRT)

  • Rate Range: 0.0945%–0.7468%, determined by NAICS code (business activity classification) statewide.
  • Base: Applies to total gross revenues (no deductions for excise taxes or operating expenses).
  • Medical Sales: Exempt from excise tax but GRT still applies to the gross revenue of medical transactions.

1.3 State‑Level Decoupling from IRC § 280E

  • Delaware decouples from federal IRC § 280E for state income tax purposes.
  • State Deductibility: Cannabis businesses may deduct ordinary and necessary expenses (rent, payroll, marketing, etc.) on their Delaware corporate or personal income tax returns.
  • COGS: As always, Cost of Goods Sold remains deductible at both federal and state levels.

3. Penalties & Compliance Risks

  • Late‑Payment Penalty: 1% of the tax due per month (up to 25%) plus interest at 0.5% per month.
  • Late‑Filing Penalty: 5% of the tax due per month (up to 50%) plus interest at 0.5% per month.
  • Enforcement: Continued noncompliance may result in fines, interest, and Division of Revenue audits; excise or GRT nonpayment can also trigger license suspension.

4. Calculating Your Cannabis Tax Liability

  1. Total Retail Sales Revenue: Sum of all recreational and medical sales.
  2. Excise Tax Calculation: 15% × (total recreational sales), rounded up to nearest cent.
  3. GRT Calculation: Applicable GRT rate × (total gross revenues, including both recreational and medical sales).
  4. Medical Adjustment: Exclude medical sales from the excise base; include medical sales in GRT base.
