Holthouse Carlin & Van Trigt LLP, known widely as HCVT, is the largest Los Angeles-based public accounting firm and ranks 31st nationally.
Founded in 1991 by Phil Holthouse, Jim Carlin, and John Van Trigt, the firm was built on a specific premise: technical excellence should drive every client engagement, and partners should be accessible, not just visible on a letterhead.
With 14 office locations spanning California, Texas, Utah, and Arizona, HCVT has grown into a firm that handles complex tax, audit, advisory, and business management work for a broad range of clients, from publicly traded companies to high-net-worth families managing generational wealth.
Key Takeaways
- HCVT is the #1 CPA firm headquartered in Los Angeles and ranks 31st in the U.S. by size.
- The firm serves clients across 11 distinct industry verticals, with particular depth in private equity, real estate, and media and entertainment.
- HCVT has appeared on Accounting Today's Top 100 list for six consecutive years and holds a Vault Top 25 ranking for employee experience.
Firm Overview: Who HCVT Serves

HCVT is not a generalist shop. The firm has built its reputation around clients with complicated financial structures, particularly partnerships and pass-through entities, and its industry focus reflects that. Here's a quick look at the verticals it covers:
| Industry Vertical | Notable Focus Areas |
|---|---|
| Private Equity & Investment Advisory | Fund structures, portfolio company tax |
| Real Estate & Hospitality | Partnership tax, opportunity zones |
| Media & Entertainment | High-net-worth individuals, talent deals |
| Technology | Startup to scale, R&D credits |
| Healthcare & Life Sciences | Compliance, transactions |
| Manufacturing, Retail & Distribution | SALT, credits, M&A |
| Affordable Housing | Tax credit compliance |
| Nonprofit Organizations | Audit, compliance |
| Professional Services (incl. Law Firms) | Partner compensation, SALT |
| High Net Worth / Family Offices | Wealth preservation, estate planning |
| Asia Pacific Practice | Cross-border tax, FATCA/CRS |
That last one deserves a mention. HCVT operates a dedicated Asia Pacific Practice, which handles cross-border tax structuring and FATCA/CRS compliance reporting work that most regional firms don't touch with the same depth.
Services: What HCVT Actually Does
There are four main service pillars.
Tax is the firm's strongest suit. HCVT's tax team handles federal, state and local (SALT), international, trusts and estates, M&A tax advisory, and a suite of credits and incentives including energy/green credits, Opportunity Zones, and the California Competes Tax Credit.
Their ASC 740 practice (accounting for income taxes) is also notable for public company clients who need technical accuracy in financial statement tax provisions.
Audit covers the standard range: financial statement audits, employee benefit plan audits, agreed-upon procedures, internal control reviews, and revenue recognition work under ASC 606.
The firm serves both private companies and employee benefit plan sponsors.
Advisory is where HCVT has been growing. Their advisory arm includes:
- M&A advisory (buy-side and sell-side)
- Quality of Earnings analysis
- Valuation advisory and gift/estate tax valuations
- CFO advisory and financial modeling
- Client accounting services (outsourced accounting)
- Technology & Transformation services
That technology and transformation practice is relatively new-ish in their positioning.
It focuses on helping businesses modernize their finance systems, integrate better data workflows, and leverage analytics for operational decisions. Not every CPA firm offers this, and HCVT appears to be leaning into it as a differentiator.
Business Management & Family Office rounding out the four pillars, this practice targets high-net-worth individuals and families who need someone to manage the full financial picture, from bill pay to entity structuring. It is a more hands-on model than traditional wealth advisory.
Treehouse: A Specific Product Worth Noting
HCVT offers something they call Treehouse, a branded solution for partnership tax compliance and reporting.
Given how complex Schedule K-1 preparation and partnership allocations can get, especially for private equity funds and real estate syndicates, this appears to be a purpose-built workflow designed to handle high-volume, detail-intensive partnership return work.
The firm's depth in pass-through entities makes this a natural fit, and it gives HCVT a named product in a space where most firms just describe the work generically.
Office Footprint
14 locations across four states:
- California (10 offices): West Los Angeles (HQ), Camarillo, Encino, Glendale, Irvine, Long Beach, Monrovia, Pasadena, Westlake Village, San Diego
- Texas: Fort Worth
- Utah: Salt Lake City, Park City
- Arizona: Phoenix
The California concentration makes sense given the complexity of California tax law.
SALT issues in California are genuinely complicated combined reporting rules, the California Competes Tax Credit, apportionment disputes, and now ongoing conversations about a state wealth tax make California-based tax counsel valuable for businesses operating here.
HCVT's scale within that market is a practical advantage for in-state clients.
Recognition and Rankings
Three notable ones, laid out plainly:
- Vault Accounting 25: Ranked as a top 25 accounting firm to work for, based on surveys of public accounting professionals rating their own employee experience.
- Accounting Today Top 100: Listed for six consecutive years in the Top 100 Firms, Top Firm in the West, and Top Firm in the U.S. categories.
- Inside Public Accounting Best of the Best: Rated on financial and operational results, not just size, which distinguishes this one from pure revenue-based lists.
The Vault ranking in particular is worth flagging for anyone evaluating HCVT as an employer.
Top 25 for employee experience in public accounting is a real signal at a time when CPA firm attrition rates are a known industry problem.
What Sets HCVT Apart From Regional Competitors
A few things stand out when you look at the firm's positioning honestly.
First, the partner-access model. HCVT explicitly builds its business model around direct partner involvement in engagements.
That is a meaningful differentiator from larger national firms where partners often sign off but aren't doing the analytical work.
Second, the technical depth in partnerships. Pass-through entity taxation, particularly for private equity and real estate, is where errors get expensive fast.
HCVT has built its identity around this area since 1991. Thirty-plus years of institutional focus on a specific technical niche tends to compound.
Third, Moore North America membership. HCVT is an independent member of Moore North America, which connects them to a network of similarly sized independent firms.
For clients with multi-state or international needs, this affiliation provides referral pathways and resource-sharing without requiring HCVT to be a Big Four firm.
A Note on Culture and Values
HCVT states four core values publicly: integrity, building success together, passion for excellence, and a commitment to diversity, equity, and inclusion. These are common enough to appear on most firm websites.
What makes this slightly more credible here is the Vault ranking. Firms that score in the top 25 for employee experience based on actual employee surveys are not usually the firms cutting corners on culture.
The two data points together stated values plus external ranking carry more weight than either alone.
Conclusion
HCVT occupies a clear position in the accounting market: a large regional firm with genuine technical depth, a strong California footprint, and a focus on complex clients who need more than compliance work.
Businesses operating in pass-through entity structures, private equity, real estate, or high-net-worth contexts, especially in California, have concrete reasons to consider HCVT over a generic national firm.
