Thread: A (Behind the IRS Curtain)
A founder who exited her company in 2019 receives an IRS letter in 2024. The letter doesn’t look like an audit notice from a few years earlier, it doesn’t reference a single tax year, it references three; it doesn’t list one entity, it lists six (her 1040, her family LLC, two operating S-Corps, a grantor trust, and a charitable remainder trust); and it asks for documentation organized by economic-family-unit rather than by return. Her CPA tells her the case has been “assigned to Large Business and International.” She has no idea what that means. The next call goes to a tax attorney, who tells her the case has been picked up by the Global High Wealth Industry Group, the unit informally known in tax-practitioner circles as the Wealth Squad.
She had never heard the term before that day. Almost no high-net-worth taxpayer has, until the letter arrives. The unit operates quietly enough that most of its work is invisible to the public, but it has been doing this work since 2010, and recent enforcement funding has expanded its operational reach materially. Most articles on IRS audits treat the experience as uniform, but the GHWI examination is fundamentally different from a standard return audit, both in scope and in the resources the IRS brings to bear. Understanding the unit’s operating model is the difference between responding effectively and responding to a process the taxpayer doesn’t recognize.
The unit most high-net-worth taxpayers don’t know exists
The Global High Wealth Industry Group was formally announced in IR-2010-90 (October 2010) as a new compliance unit within the IRS Large Business and International (LB&I) division. Its remit was, and remains, examining the “wealth platforms” of high-net-worth taxpayers: the network of pass-through entities, trusts, closely held businesses, and related-party transactions that surround a high-net-worth individual’s personal Form 1040. The unit operates as part of LB&I rather than as part of the Small Business / Self-Employed division because the underlying entities are typically more complex and more international than the SB/SE caseload supports.
GHWI does not audit single returns. It audits economic family units. When a GHWI examination opens on a target, the same case team simultaneously examines the target’s pass-through entities (Forms 1120-S, 1065), family trusts (Form 1041), closely held corporations the target controls, frequently the spouse’s and adult children’s returns where they intersect with the target’s, and any international information-return filings (Forms 5471 for controlled foreign corporations, 8938 for FATCA-reportable financial assets, 8865 for foreign partnerships, and FinCEN 114 for foreign financial accounts).
The threshold criteria
IRS public statements about GHWI emphasize complexity and indicia of wealth rather than a strict dollar threshold. The original 2010 framing in IR-2010-90 referenced taxpayers with assets in the tens of millions; the criteria have evolved, and the IRS has been deliberately non-specific about current thresholds in public documents. TIGTA report 2020-30-016 (covering the early High Wealth Initiative results) and TIGTA 2024-30-018 (covering recent IRA-funded examinations) document the pattern GHWI prioritizes: significant wealth indicators combined with structural complexity, multi-entity ownership, international components, sophisticated planning structures, and substantial pass-through income.
The practical implication: high-net-worth taxpayers should not assume they’re below a specific GHWI threshold. The unit’s case selection emphasizes pattern over dollar count. A $5M-net-worth individual with a complex multi-entity structure may attract GHWI attention faster than a $50M-net-worth W-2 wage earner with a simple return.
The multi-entity examination model
The typical GHWI examination involves three or more tax years, six to ten related entities, and 1,500 to 3,000+ examiner hours over a 3-5 year arc. The case team is multi-disciplinary: a lead revenue agent, an international examiner, a flow-through specialist, and sometimes a valuation engineer for closely held interests. The IDR (Information Document Request) packages are extensive and typically organized by economic-family-unit rather than by return, meaning the same fact pattern is examined across all the related entities simultaneously, rather than one return at a time.
The examination scope routinely covers compensation structures (deferred comp under IRC §409A, equity grants), related-party transactions (intercompany loans under IRC §267, gifts, sales between family members and entities subject to special-valuation rules under IRC §2701-§2704, intercompany pricing under IRC §482, Form 709 gift-tax filings), family-office expense allocations (§212 income production, §183 hobby-loss exposure, §280A(g) home rental), and foreign disclosures. The IRS knows that high-net-worth tax positions interlock across entities; the unit is designed to examine the interlock, not the individual returns.
The IRA 2022 enforcement-funding effect
The Inflation Reduction Act of 2022 (P.L. 117-169) §10301 directed roughly $80 billion in supplemental IRS funding over 10 years, of which approximately $46 billion was originally earmarked for enforcement. Subsequent legislation, the Fiscal Responsibility Act of 2023 and FY 2024 appropriations, clawed back portions of that allocation, leaving a smaller but still substantial operational increase. GHWI was an explicit beneficiary of the enforcement portion: TIGTA report 2024-30-018 documents that GHWI examiner staffing and active case load increased materially through FY 2023 and FY 2024, with the case mix shifting toward larger and more complex matters. The practical consequence for a taxpayer caught unprepared is the examination shape itself: multi-year, multi-entity, with 3-5 year resolution arcs rather than the 12-18 months a single-return examination typically closes within.
The audit-rate effect at the upper end of the wealth distribution is real and observable in the IRS Data Book Section 17 tables. Returns with AGI > $5M, and especially > $10M, audit at rates that grew meaningfully through FY 2023 and FY 2024. Most of that growth reflects expanded GHWI capacity rather than a broader shift in IRS examination posture.
What HNW taxpayers can do proactively
The defining feature of GHWI examinations is that they are long, broad, and document-intensive. Documentation hygiene that works for a single-return audit does not survive a multi-entity, multi-year examination unless it is maintained as ongoing discipline rather than as triggered response. The work is not glamorous, and it has to be done before the IDR arrives, because the documentation a practitioner can assemble after the fact rarely matches the documentation a practitioner could have maintained in real time.
The discipline rests on four maintained files. The first is FATCA and FBAR hygiene: every foreign financial account above the FinCEN 114 threshold ($10,000 aggregate at any point during the year, per 31 USC §5314) and every reportable foreign asset above the Form 8938 threshold (varies by filing status from $50K to $600K, per IRC §6038D) needs current-year filings even when the underlying account balances are modest. Catch-up filings are visible on the account and become examination triggers in their own right.
The second is a valuation-support file for closely held interests. Annual valuations of family-LLC or closely held S-Corp interests, particularly when they have downstream transfer-pricing, gift-tax, or estate-planning implications, belong in an ongoing file rather than commissioned ad hoc when the IDR lands. GHWI valuations are challenged frequently, and the difference between a contemporaneous valuation and a retroactive one is usually the difference between a defensible position and an examination concession.
The third is a §409A administration log. Deferred-compensation arrangements require strict adherence to the deferral-election and distribution-event rules; any deviation produces taxable income at the executive level plus a 20% penalty. Election forms, distribution-event documentation, and plan-amendment history need to be complete before the examination opens, not assembled under deadline.
The fourth is a related-party-transaction memo file. Every material loan, gift, sale, or service arrangement between the principal, family members, and the entity structure deserves a contemporaneous memo describing the business purpose, the terms, and the supporting documentation. The intercompany pricing standards under §482, the related-party loss disallowance rules under §267, and the special-valuation rules under §2701-§2704 are all live issues in a GHWI examination, and the contemporaneous memo is the document that makes the position defensible.
What to do if a GHWI letter arrives
The single most important first step is engaging representation before any direct response. GHWI examinations are not the engagement where the principal answers the IDR personally; the procedural posture is different from a standard field audit, the document-production discipline is different, and the multi-disciplinary case team is doing structured examination work that benefits from structured response. Practitioners experienced with LB&I procedures handle the IDR sequencing, the privilege-and-work-product analysis, and the multi-entity coordination differently than a generalist would.
The cases that resolve well in GHWI typically share two features: representation that engaged early, and documentation that was complete before the IDR arrived. The cases that resolve poorly typically share the opposite features.
