Hiring a CPA for your cannabis business is not simple. The wrong choice can drain your cash, trigger audits, or freeze your growth. You face strict rules, fast changes, and harsh penalties. You need someone who understands cannabis law, tax traps, and real-day-to-day pressure. You also need clear books that match state and federal demands. For example, dispensary accounting in Brooklyn, NY must meet tight local rules and federal eyes at the same time. Many CPAs claim they can handle cannabis work. Very few prove it when trouble starts. Before you sign an engagement letter, you should pause and ask direct questions. These questions help you see who can protect you and who might expose you. This blog shares three focused questions that cut through promises and reveal real skill, real experience, and real accountability.
1. Do you understand cannabis tax rules and IRS Section 280E
Your first question should target tax law. Cannabis remains illegal at the federal level. The IRS treats your business as a drug seller under Section 280E. You cannot deduct most normal costs. You can only claim the cost of goods sold. That single rule can decide if you stay open or close.
Ask the CPA to explain, in plain words, how 280E works. Then ask how it applies to your shop, grow, or lab. A strong answer should cover three points.
- What counts as cost of goods sold for you
- What costs you must track but cannot deduct
- How they have handled IRS exams for other cannabis clients
You should also check if they use trusted sources. The IRS keeps clear public guidance on cannabis and 280E. Then see if the CPA gives the same message. If their story does not match IRS text, walk away.
Next, ask about state tax. Some states follow 280E. Some do not. Some let you add back costs that the IRS blocks. A good CPA will show how they separate federal and state returns. They will also warn you when state rules change. You should feel informed and calm, not confused or scared.
2. What real cannabis experience do you have
The second question cuts through labels. Many CPAs say they serve “high-risk” work. That phrase means nothing by itself. You need proof that they handle cannabis every week, not once a year.
Start with three direct checks.
- How many cannabis clients do they serve today
- What types of licenses those clients hold
- How long have they worked with cannabis companies?
Ask if they work with dispensaries, cultivators, manufacturers, and delivery businesses. Each license type has its own pain points. For example, a grower needs strong inventory and cost tracking. A retail shop needs clear cash controls and daily sales reports. A lab faces strict testing records. One CPA might handle all. Another might focus on one type. You should know that before you sign.
You can also ask about training. Many state agencies and universities offer free or low-cost cannabis finance guides. For example, the Congressional Research Service report on marijuana policy shows how federal rules shape markets and risk. Ask the CPA what public reports or courses they use to stay current. A strong answer shows steady study and respect for the law.
Then request examples. You do not need names. You need stories. Ask the CPA to describe one hard tax issue they solved for a cannabis client. Ask what went wrong, what they fixed, and what changed for the client. Look for clear steps and honest talk about limits. Vague claims signal weak skill.
3. How will you protect me through systems, not guesswork
The third question looks at daily work. Cannabis rules punish sloppy habits. You cannot rely on memory or trust alone. You need tight systems that run the same way each day. Your CPA should design and test those systems with you.
Ask how they will set up your chart of accounts, inventory tracking, and cash controls. Then ask what they expect you and your staff to do each day, week, and month. A good CPA gives you a clear checklist. They do not hide work behind jargon.
Use a simple comparison like the table below when you interview more than one CPA.
| Key factor | Strong cannabis CPA | General CPA
|
|---|---|---|
| 280E knowledge | Explains 280E and cost of goods sold in clear terms | Knows 280E by name but gives vague or mixed answers |
| Cannabis clients | Serves several active cannabis clients with different licenses | Has one past client or none |
| Systems and controls | Provides written checklists and standard steps | Relies on verbal advice and “call me if you need help” |
| Audit support | Has handled IRS or state audits for cannabis | No direct audit work with cannabis |
| Education and sources | Uses IRS, state, and university material, shares links with you | Cannot name clear sources |
Finally, talk about fees and scope. Ask what is included, what costs extra, and how often you will meet. A strong CPA sets fixed touchpoints. They might meet each month to review numbers, each quarter to plan taxes, and each year to reset goals. They should also tell you how fast they respond when the IRS or state calls.
These three questions do more than fill time. They protect you, your staff, and your family from harsh shocks. When you choose a CPA who understands cannabis tax, has real experience, and builds strong systems, you gain clear ground under your feet. You can face inspections, audits, and change with steady nerves and clean books.
