Specialist CPA Support for High-Stakes Engagements

Audit deadlines, IRC 280E exposure, transaction diligence, and regulatory change do not wait for a generalist to get up to speed. Our accounting, tax, audit, and advisory teams operate as one PCAOB-registered firm, with dedicated practice leads across eight industries.

A lender, investor, or board is asking for audited financials Covenant and grant language names a specific level of assurance, and reading it correctly decides scope, cost, and timeline. Our audit team scopes to the requirement and commits to a delivery date at engagement rather than after fieldwork begins. Audit & Assurance → Finance is running on your time instead of a system A six-week close and a margin question nobody can answer are process problems, not effort problems. Our CFO team builds the thirteen-week cash forecast, the close calendar, and the unit economics reporting your decisions actually depend on. Outsourced CFO → You hold both medical and adult-use cannabis licences Since April 2026 those carry different federal tax treatments, so every shared cost has to be split between two regimes with no IRS default method to fall back on. Our cannabis practice has handled IRC 280E allocation since 2016 and documents the methodology to survive examination. Cannabis Accounting → There is an LOI on the table, or one coming Deals reprice in diligence, not in negotiation, and the findings that move the number are almost always accounting. Our transaction team runs quality of earnings and financial due diligence while you still control the timing. Transaction Advisory → A filing deadline is close, or has already passed Extensions, missed deadlines, and multi-year non-filing each take a different route, and penalties compound while the question goes unanswered. Our tax team establishes which years are open, quantifies the exposure, and files. Tax Planning & Compliance → You own a CPA firm and are planning the exit Most owners underestimate how long a clean transition takes and how much value leaks in a rushed one. We acquire practices directly as the buyer, with no broker in the middle, protecting client continuity and retaining your staff. Succession & Acquisitions →

Real estate industry accounting and tax services

Real Estate

Tax strategy for investors, developers, and operators

Bonus depreciation returned to 100% permanently under the One Big Beautiful Bill Act, which changed the arithmetic on every cost segregation study. We model whether you can actually use the deduction before anyone commissions one, then handle entity structuring, investor reporting, and the Form 3115 catch-up on properties you already own.

Cannabis industry accounting and 280E tax services

Cannabis

Specialized compliance for a complex industry

Since the April 2026 rescheduling of state-licensed medical cannabis to Schedule III, operators holding both medical and adult-use licences run two federal tax regimes at once. Adult-use remains under IRC 280E, where cost of goods sold allocation is the only lever that matters. We handle that allocation, the activity-level split between regimes, and the multi-state compliance underneath both.

What GreenGrowth CPAs Clients Say

Clients choose GreenGrowth CPAs for accuracy, clarity, and long-term advisory support.

"Great team of highly qualified professionals dedicated to outstanding customer service. In an industry that can be somewhat like the wild west due to its lack of maturity and evolving standards, it was refreshing to work with a team that does things by the book where others may cut corners. If peace of mind is important to you, your employees, and the future of your business, I recommend the team at GreenGrowth."

David Spence

"GreenGrowth CPAs knock it out of the park with their service. They provide loads of knowledge and practice to streamline your business. They are always willing to meet and discuss any issues or even help with a game plan on how to approach different verticals within the industry. Any time I bring new people on board, they are impressed with the quality and information that GreenGrowth brings to the table."

Austin Caby

"Their attention to detail and holistic approach has made them a high-quality firm for a reasonable price. They have been key in helping us develop our cannabis business and also an accounting infrastructure where our former firm had failed. Derek (the founder) has so much experience with non-profit work that he is also good communicating with not only multiple members of the team, but also board members at their level of accounting expertise. We will gladly endorse them for their good work."

Services are delivered remotely with secure document exchange and regular video check-ins, and we serve clients across the United States and select international engagements.

What licences and registrations does GreenGrowth CPAs hold?

GreenGrowth CPAs is a registered public accounting firm with the Public Company Accounting Oversight Board (PCAOB) under Firm ID 6580, an AICPA member firm, and a member of both the AICPA Governmental Audit Quality Center (GAQC) and the AICPA Employee Benefit Plan Audit Quality Center (EBPAC). The firm holds CPA firm registration with eight state boards of accountancy: California, Texas, New Jersey, Oregon, Michigan, Arkansas, Connecticut, and North Carolina, and is registered with the California State Controller's Office through CPADS for public agency audits. GAQC membership is required for certain governmental and single audit engagements, and EBPAC membership supports employee benefit plan audits including Form 5500 filings.

Is GreenGrowth CPAs AICPA and PCAOB registered?

Yes. GreenGrowth CPAs is an AICPA member firm and is registered with the Public Company Accounting Oversight Board (PCAOB) in the United States under Firm ID 6580. This registration enables us to perform audits for publicly listed cannabis multi-state operators on U.S. exchanges including the NYSE, NASDAQ, and OTC, and GreenGrowth appears as independent registered public accounting firm in audited financial statements filed with the Securities and Exchange Commission.

Can one firm handle our accounting and our audit?

It depends on which audit. Under SEC and PCAOB standards the answer is no, since those rules prohibit auditing statements the firm helped produce. In a private company audit driven by a lender, investor or board, the AICPA framework is different and often permits both, provided management takes responsibility for the records and appropriate safeguards are documented. Plenty of firms apply the strictest rule everywhere, which sends private companies out to find a second provider they never needed. We establish which combination your situation permits at the outset.

How long has GreenGrowth CPAs been in business?

GreenGrowth CPAs was founded in 2016. Our team brings over 65 years of combined accounting, tax, and advisory experience, and we have served more than 1,500 clients across our industry practices, with a 98% client retention rate driven by personalized service and long-term advisory relationships rather than transactional engagements.

The fastest path is to schedule a free consultation through our website. A 30-minute discovery conversation helps us understand your business, current financial systems, and priorities.
