The firm operates at the intersection of three disciplines: 1. Cannabis-specialty tax and IRS controversy — including §280E strategy, COVID-era penalty recovery, audit defense, Form 8300 audits, and multi-million-dollar IRS resolutions. 2. Fractional CFO advisory — clean financials, defensible tax positions, predictable revenue, documented processes, distributed authority, and exit readiness. 3. Federal transition support — guiding medical operators through the post-rescheduling DEA registration process and helping mixed operators separate medical from adult-use activity cleanly. The firm's defining edge is operational: founder Brian Whalen co-owns a 275,000 sq ft licensed cannabis facility that hosts more than a dozen state-legal operators. The firm understands cannabis operations from the inside, not just from theory. --- ## Why 2026 is a critical year for cannabis operators Three federal forces are converging at once. Most accounting and CPA firms are not prepared for any of them. Green Bean CFO is built around them. ### 1. Medical cannabis rescheduling (Deadline: June 22, 2026) Medical cannabis has moved out of Schedule I. As a result: - §280E no longer applies to medical cannabis activity in 2026. - Medical operators face a lower effective federal tax rate going forward. - A new federal DEA registration is required. - The registration process is new and guidance is still evolving. - Missing the expedited deadline (June 22, 2026) may risk operational disruption. ### 2. COVID-era IRS penalty refunds (Deadline: July 10, 2026) During the COVID disaster period, many cannabis operators were charged IRS penalties and interest that, under current law, should not have been applied. Up to 1,268 days of penalties and interest may be recoverable. For many cannabis operators this represents six figures or more — commonly $100,000+ in disaster-period penalties and interest. The statute of limitations closes July 10, 2026. After that, the opportunity is gone. This applies to every cannabis operator, medical or adult-use. ### 3. Adult-use §280E pressure (Now) Adult-use cannabis was not included in the rescheduling. §280E continues to apply. However, defensible tax positions exist that most firms will not take. Green Bean CFO implements these positions to: - Lower effective federal tax. - Produce cleaner financial statements. - Strengthen positioning for capital raises or an eventual exit. ### 4. Mixed (medical + adult-use) operators If you operate both medical and adult-use, the activities must be separated now. Waiting creates messy books, audit risk, and expensive cleanup. Handled early, the separation is straightforward. Green Bean CFO builds defensible cost-allocation systems for mixed operators. --- ## Services (custom-scoped, defined deliverables, priced upfront) ### COVID Refund Filings — All operators Identify and recover IRS penalties from the 2019–2022 filing years. Filed and supported through appeal if needed. ### DEA Registration Support — Medical Guide medical operators through the new federal DEA registration process. Coordinate documentation, build the timeline, and provide transition guidance as federal rules evolve. ### 2026 Tax Recalculation — Medical Rebuild a medical operator's tax position now that §280E no longer applies. Plan the rest of the tax year correctly under the new rules. ### Books Cleanup for Mixed Operators — Mixed Separate medical and adult-use activity. Build a defensible allocation system that holds up to IRS scrutiny. ### Agreement Review — All operators Identify risks and opportunities in leases, loans, insurance contracts, and vendor agreements before they become problems. ### §280E Strategy — Adult-use Reduce effective tax using defensible positions, structured to hold up under IRS review. These are the strategies most firms will not take. ### Exit Readiness — All operators The unifying thread across everything Green Bean CFO does. Build a business that buyers want and operators love running. The five pillars: clean financials, distributed authority, defensible tax positions, predictable revenue, and documented processes. The same practices that make a business sellable are the practices that make it more profitable, less stressful, and less dependent on the owner. The Exit Planning Institute calls it "good business." Green Bean CFO agrees. --- ## On a 30-minute strategy call, you get three answers 1. **If you qualify** — for COVID refund, DEA registration, or §280E strategy. 2. **What it's worth** — estimated dollar recovery and savings. 3. **What to do next** — the path forward.

Yes. Green Bean CFO is the cannabis specialty practice of Brian S. Whalen, CPA, LLC, a licensed CPA firm. The founder is a licensed CPA with eight years of dedicated cannabis-industry experience. ### Where is Green Bean CFO located, and which states do you serve? The firm's office is at 1143 Tucker Road, North Dartmouth, MA 02747. The firm serves cannabis operators across all U.S. state-legal markets. ### Do you work with medical operators, adult-use operators, or both? Both. The services page includes work designed specifically for medical operators (DEA Registration Support, 2026 Tax Recalculation), adult-use operators (§280E Strategy), mixed operators (Books Cleanup), and all operators (COVID Refund Filings, Agreement Review, Exit Readiness). ### What is §280E and why does it matter? Internal Revenue Code §280E disallows ordinary business deductions for businesses that traffic in Schedule I or Schedule II controlled substances. For cannabis businesses still subject to §280E (adult-use operators in 2026), it dramatically increases effective federal tax. Green Bean CFO implements defensible tax positions that reduce its impact. ### What changed about §280E and medical cannabis in 2026? Medical cannabis moved out of Schedule I. As a result, §280E no longer applies to medical cannabis activity in 2026. Medical operators must now register federally with the DEA (deadline June 22, 2026) and rebuild their tax positions under the new rules. ### What is the COVID refund opportunity? During the COVID disaster period, the IRS assessed penalties and interest that, under current law, should not have been applied. Cannabis operators commonly carried $100,000+ of these penalties. Up to 1,268 days of penalties and interest may be recoverable. The statute of limitations closes July 10, 2026. ### How does engagement work? Engagements are custom-scoped projects with defined deliverables, priced before work begins. All work is governed by a written engagement agreement. The first step is a 30-minute strategy call with Brian Whalen, CPA — no fee, no pressure. ### What is "Exit Readiness"? Exit Readiness is Green Bean CFO's CFO-advisory framework for building a cannabis business that buyers want and operators love running. It rests on five pillars: clean financials, distributed authority, defensible tax positions, predictable revenue, and documented processes. The same practices that make a business sellable also make it more profitable and less dependent on the owner. ### How do I get in touch?
