American Property Tax Co

What American Property Tax Co does

American Property Tax Counsel (APTC) is a national alliance of independent property tax law firms operating as co-counsel since 1994. Headquartered at 2512 Artesia Blvd., Ste 200 in Redondo Beach, California, APTC connects commercial property owners with specialized property tax attorneys across 35+ U.S. states and Canada through its 125+ attorney network. Member firms provide legal services including assessment reviews, strategic tax appeals, high-stakes litigation, multi-state portfolio coordination, incentives and abatement advisory, pre-acquisition assessment risk reviews, compliance monitoring, and valuation methodology guidance. APTC explicitly does not represent residential homeowners and concentrates exclusively on commercial and industrial real estate across asset classes ranging from multi-family housing and office buildings to hotels, healthcare facilities, retail centers, and nuclear power plants.

The alliance operates under a sales-led go-to-market model in which prospective clients identify the relevant state on APTC's Find an Attorney directory and are connected to the local member firm, while APTC coordinates strategy centrally for multi-state portfolios. There is no software product, no public API, no disclosed patents or trademarks, and no proprietary technology platform; APTC's "product" is coordinated legal expertise combined with a content-marketing engine comprising an industry insights blog, email newsletter, and an annual client seminar that doubles as a client acquisition and retention touchpoint (the 2026 edition scheduled for September 23-25 in Chicago).

APTC is a private professional association with no parent company, no disclosed funding rounds, no M&A activity, and no external institutional investment. The organization is governed by elected officers drawn from member firms, with J. Kieran Jennings (Siegel Jennings Co.) as President and Linda Terrill (Property Tax Law Group) as Past President. Member firms remain independently owned and bill clients through quote-based professional services fees tied to matter complexity, jurisdiction, and scope, with multi-year engagements and no publicly disclosed standard pricing tiers. Cumulative client outcomes highlighted by APTC include over $2.5 billion in property tax value reductions, 500+ reported appellate cases handled, and 500+ legislative and regulatory amendments influenced by member attorneys.

Scale indicators7 records

Recent moves4 records

Expansion highlights4 records

Direct peers

• Ryan, LLC: Ryan is the largest dedicated property tax consulting firm in North America, offering commercial property tax compliance, appeals, and valuation services. It is the closest scaled, single-firm direct competitor to APTC's national property tax appeal alliance, often competing head-to-head for the same large portfolio mandates.
• Altus Group: Altus Group is a commercial real estate advisory and technology firm with a substantial property tax practice serving U.S. and Canadian CRE owners. It competes directly with APTC on multi-jurisdictional property tax appeals and valuation services, and adds data/software capabilities APTC lacks.
• Marvin F. Poer & Company: Marvin F. Poer is a dedicated commercial property tax consulting firm with national coverage. It is one of the long-standing direct competitors to APTC member firms, particularly for multi-jurisdiction portfolios, and competes on similar property tax appeal services.

Broad incumbents

• BDO USA: BDO USA operates a national property tax practice within its broader accounting and advisory platform, serving CRE owners across jurisdictions. It competes with APTC on commercial property tax appeals but as part of a much wider professional services portfolio.
• Deloitte Tax LLP: Deloitte's Tax practice includes a commercial property tax group serving large enterprise CRE owners and investors. It is a broad incumbent that overlaps with APTC on multi-state property tax advisory but is not specialized exclusively to property tax.
• CBRE Group: CBRE, the world's largest commercial real estate services firm, offers property tax advisory through its valuation and advisory service lines. It competes for large CRE owner mandates and offers a broader suite of services (brokerage, valuation, advisory) beyond what APTC provides.
• Jones Lang LaSalle (JLL): JLL provides commercial real estate services including property tax consulting and valuation, serving enterprise CRE owners globally. Like CBRE, it is a broad incumbent with overlapping property tax advisory capabilities but does not specialize exclusively in property tax appeals.
• Kroll (formerly Duff & Phelps): Kroll's Tax Services segment includes commercial property tax and valuation advisory for CRE owners. It competes with APTC on high-stakes valuation disputes but offers these services within a much broader financial advisory and risk consulting platform.
• CBIZ, Inc. CBIZ is a national professional services firm offering property tax consulting as part of its tax and advisory platform. It competes with APTC on commercial property tax compliance and appeals but as a smaller-scale incumbent within a broader financial services portfolio.

Others

• Tyler Technologies (Assessment & Permitting): Tyler Technologies provides software used by county assessors for property assessment and valuation, including products from the legacy Assessment Technologies business. As an enabling technology provider to assessors, it represents the supply-side technology that APTC attorneys engage with and argue against in appeals.
