What We Do
Tax, Audit, and CFO Services in Los Angeles
Most clients look for a Los Angeles CPA for one of three reasons. A tax return or position needs planning, a lender, customer, or investor wants a report, or the books need a real finance team. GreenGrowth CPAs covers all three, with a dedicated lead for each service line.
Tax Planning and Compliance
Business and individual tax preparation, year-round planning, and multi-state filings, plus Section 174A expensing and R&D credits for companies building product. We model positions before year end, while timing can still change the result.

Common Situations
Who Comes to Us From Los Angeles
Five situations bring most new clients to us. Each maps to a dedicated team inside the firm, so nobody starts by explaining their business to a generalist.
| The situation | Who it hits | What we do |
|---|---|---|
| Outgrowing tax software and do-it-yourself bookkeeping | Main Street businesses, restaurants, retail, and service firms | Monthly bookkeeping plus business and owner returns from the same team. |
| Development costs were capitalized and never recovered | Startups and software companies that built product from 2022 to 2024 | Section 174A recovery elections, R&D credit modeling, and quarterly estimate resets. |
| Enterprise customers demand a SOC 2 report before signing | SaaS and services companies moving upmarket | Readiness assessment, then SOC 2 Type I and Type II, timed so the report lands before the deal stalls. |
| Investor reporting the current books cannot produce | Funded companies between raises | Outsourced CFO support: monthly close, runway modeling, and board-ready reporting. |
| Founder income spread across equity, entities, and states | Founders, partners, and high net worth owners | Coordinated personal and entity tax planning, so no return gets filed in isolation. |
Advisory
Startup CPA and CFO Support for Silicon Beach and Beyond
Founders in Santa Monica, Venice, and across the city look for a startup CPA when the questions outgrow the bookkeeper. How do you recover capitalized development costs? Can the R&D credit offset payroll tax before profitability? What do the books need to look like before a raise?
Advisory engagements cover Section 174A elections, credit studies, cap table and equity compensation questions, and fractional CFO support. That support turns the monthly close into investor-ready reporting.
One conversation scopes it. Schedule a free consultation and bring the numbers you are working with.
Cannabis Tax Facts
Cannabis Accounting for Los Angeles Operators
Los Angeles cannabis operators face state excise tax, federal 280E, and local business taxes at the same time. The table below covers the state and federal rules that shape most of our cannabis engagements.
| Rule | What it says | What it means for you |
|---|---|---|
| California cannabis excise tax | The rate is 15% of a retailer's gross receipts. AB 564 restored 15% on October 1, 2025, and bars any new rate adjustment before the 2028-29 fiscal year. | Retailers can plan on 15% through June 30, 2028. We build that rate into pricing and cash forecasts. |
| California 280E nonconformity | R&TC Section 17209 lets licensees filing under the personal income tax law deduct ordinary business expenses on the California return. SB 167 (2024) extended the rule, and the section now repeals on January 1, 2030. | Your California return can deduct expenses that 280E blocks on the federal return. We prepare both returns with that difference in mind. |
| Federal 280E | State-licensed medical marijuana moved to Schedule III effective April 28, 2026. Adult-use cannabis remains Schedule I, so 280E still applies to it. | Mixed medical and adult-use operators need clean revenue and cost tracking. Treasury has said its coming guidance will apply relief to the full tax year that includes the effective date. |
| Local cannabis business taxes | Cities set their own cannabis business taxes, and rates vary by city and license type. | We confirm the current rate with the city's finance office before each filing. |

Frequently Asked Questions About Our Los Angeles CPA Services
Choosing and working with us
Does GreenGrowth CPAs have an office in Santa Monica?
Yes. Our office is at 520 Broadway #200, Santa Monica, CA 90401, and it serves clients across Los Angeles. Our headquarters is in Irvine, and clients can meet with us in person or work with us remotely.
Who is the best CPA in Los Angeles?
The right CPA depends on your business, so start with a few checks. Confirm the CPA's license on the California Board of Accountancy website. Then ask whether the firm knows your industry and can cover the tax, audit, and advisory work you need. Clients choose GreenGrowth CPAs because we are PCAOB registered, an AICPA member firm, and have served more than 1,500 clients since 2016. Our dedicated cannabis and technology work is another reason.
Where is GreenGrowth CPAs' Los Angeles office?
Our Los Angeles-area office is in Santa Monica at 520 Broadway #200, Santa Monica, CA 90401, a short drive from Century City, Beverly Hills, and West Hollywood. Many clients also work with us remotely through a secure client portal, video calls, and phone. Our headquarters is at 200 Spectrum Center Dr, Suite 300, Irvine, CA 92618.
What services do you offer in Los Angeles?
We offer business and individual tax planning and compliance, bookkeeping and accounting, outsourced CFO services, and audit and assurance from a PCAOB-registered firm, including SOC 1 and SOC 2 reports. Our cannabis practice also handles 280E planning and California cannabis tax.
Do you work with businesses in Century City?
Yes. Century City is one of the Los Angeles areas we serve, along with Santa Monica, Beverly Hills, West Hollywood, and Downtown LA. Our nearest office is in Santa Monica at 520 Broadway #200, and clients anywhere in the county can also work with us remotely.
Do you work with cannabis businesses in Los Angeles?
Yes. We work with licensed cannabis operators on accounting, 280E cost allocation, and California tax. California's cannabis excise tax is 15% through June 30, 2028 under AB 564. California also lets licensees filing under the personal income tax law deduct ordinary business expenses under R&TC Section 17209.
How do I book a consultation?
Start online at our Get Started page or call (800) 674-9050. Tell us the deadline or decision you face, and we will match you with the right practice lead. The first consultation is free and takes place by phone or video.
Tax and reporting
When does a startup need a SOC 2 report?
Usually when enterprise procurement starts asking for one. Type I assesses control design at a point in time. Type II tests operation across an observation period of several months, so starting late can cost a sales quarter.
Does GreenGrowth CPAs prepare individual tax returns?
Yes. We prepare individual returns alongside business returns, which matters most for owners whose income flows through partnerships, S corporations, or equity. Coordinating both keeps a decision on one return from creating a surprise on the other.
Can GreenGrowth CPAs handle both our bookkeeping and our audit?
Under SEC and PCAOB standards, no, because those rules prohibit auditing statements the firm helped produce. In a private company audit for a lender, investor, or board, the AICPA framework often permits both if management takes responsibility for the records and the firm documents safeguards. We confirm which combination your situation permits at the outset.
Across the Firm
GreenGrowth CPAs Across California
Los Angeles work draws on the whole firm. Residents and owners start at individual tax services, and licensed operators at the cannabis accounting hub. Companies building product start at the technology page, and companies selling into the enterprise start at SOC audit services. Founders with multi-entity income can begin with high net worth services, and growing companies can add outsourced CFO support. Whichever Santa Monica CPA or Los Angeles CPA question brings you here, the same California team sits behind the page.
