TAC Insurance Consulting, LLC

TAC Insurance Consulting, LLC, a veteran-owned sole proprietorship based in Bonita Springs, Florida, provides expert witness services in tax litigation, forensic accounting, and insurance-industry disputes exclusively to the Internal Revenue Service as a prime contractor on a full-and-open (non-set-aside) competitive basis. All 18 awards in the portfolio are IRS contracts across the Department of the Treasury; TAC competes across labor-hour definitive contracts and purchase orders with ceiling values ranging from $75,950 to $706,868, with ultimate completion dates extending through 2031.

TAC's customer concentration is absolute — 100% of awards (all 18 contracts, $4.5 million combined potential value) come from a single customer: the Internal Revenue Service. The vendor holds no parent vehicles, GWACs, or BPAs; each contract is a direct award. Recent representative work includes a $706,868 five-year definitive contract awarded May 30, 2023 for expert witness services supporting IRS audit defense litigation, forensic accounting, and tax abatement; a $334,223 definitive contract awarded July 26, 2023 for expert witness services with FAR 52.222-90 incorporation supporting Executive Order 14398; and three purchase orders awarded in summer 2026 (July 14, July 30, and August 5) for expert witness services valued at $215,030, $215,155, and $232,281 respectively, with performance locations in Bonita Springs, Atlanta, and Washington DC. All contracts use labor-hour pricing with no set-aside designation.

Activity has grown modestly — one award in 2021, three in 2022, four in 2023, five in 2024, and three in 2026 — establishing a pattern of recurring IRS procurements for specialized tax expertise. Five awards carrying combined potential value of $1.8 million reach ultimate completion within the next twenty-four months, presenting recompete exposure. TAC has accumulated $3.3 million in obligated dollars across its 18-contract portfolio (73% of the $4.5 million combined potential value), reflecting invoiced revenue from IRS expert witness engagements. The vendor's footprint maps to PSC code Support—Professional: Expert Witness across NAICS 541900 (All Other Legal Services), 541990 (All Other Professional, Scientific, and Technical Services), and 524990 (All Other Insurance Related Activities), reflecting the insurance-industry and forensic-accounting depth required by IRS complex-tax litigation and dispute resolution work.
