A key component in promoting the highest degree of voluntary compliance on the part of taxpayers is helping them understand and meet their tax responsibilities while also enforcing the law with integrity and fairness to all. This article provides general guidance including frequently asked questions for taxpayers in the marijuana industry.

I.R.C. § 280E and the Marijuana Industry

Businesses that traffic marijuana in contravention of federal or state law are subject to the limitations of Internal Revenue Code (IRC) Section 280E. The Marijuana Industry FAQs, linked below, address federal tax filing and information report requirements specific to taxpayers in this industry.

Income Reporting

Income from any source is taxable and taxpayers are generally required to file a tax return to report that income to the IRS. Many marijuana-industry businesses conduct transactions in cash, which need to be reported, like any other form of payment. See Publication 334, Tax Guide for Small Business, for more details.

Cash Payment Options

Cash payment options are available for unbanked taxpayers. Some IRS Taxpayer Assistance Centers accept cash. Call 844-545-5640 for a location near you to schedule an appointment. Publication 5435 (PDF) provides additional details about cash payment options.

Large Cash Amounts

Any person in a trade or business who receives more than $10,000 in cash in a single transaction or in related transactions must file Form 8300 (PDF), Report of Cash Payments Over $10,000 Received in a Trade or Business, within 15 days after receiving payment.

Estimated Payments

Small business taxpayers often need to make quarterly estimated tax payments to cover their tax obligation. Form 1040-ES, Estimated Tax for Individuals, will help to figure these payments. IRS Direct Pay is the fastest and easiest way to make these payments. The Treasury Department’s (EFTPS) system is also an option.

Records

Good records assist in monitoring a business’s progress, tracking deductible expenses and can substantiate items reported on tax returns. A good recordkeeping system includes a summary of all business transactions. Generally, it is best to record transactions daily.
