Doctor challenges Puerto Rico residency ruling and $5.8 million deficiency
Gary V. Karakashian v. Commissioner. United States Tax Court. No. 3119-26.
A dermatologist is asking the Tax Court to reverse a $5.77 million tax bill and a $4.29 million civil fraud penalty. The IRS claims he was not a true resident of Puerto Rico and wrongly left out Puerto Rico income from U.S. taxes.
What Happened
Dr. Gary Karakashian filed a petition in Tax Court to challenge an IRS Notice of Deficiency for 2021. The IRS claimed:
$5,774,740 in additional income tax
$4,293,843.75 in civil fraud penalties under §6663
The dispute centers on the main issue: whether Karakashian was a bona fide resident of Puerto Rico under §937(a). If so, he could exclude a large amount of Puerto Rico income from U.S. federal tax under §933.ed he failed:
physical presence test
tax home test
closer connection test
The IRS also questioned a group of Puerto Rico entities, captive insurance deals, management companies, and investment structures connected to the taxpayer’s medical practice and investments.
Human civilization has now produced a world where dermatologists apparently maintain captive insurers, transfer pricing studies, Puerto Rico management entities, telehealth operations, reinsurance pools, and six-million-dollar intercompany loan chains. Accountants everywhere just nodded grimly and opened another spreadsheet.
Why It Matters
Puerto Rico residency disputes remain a major IRS enforcement priority, especially where taxpayers exclude large amounts of capital gain or business income under §933.
The case combines several areas currently receiving heightened scrutiny:
Puerto Rico Act 60 residency claims
captive insurance structures
Subpart F and GILTI issues
management company arrangements
economic substance penalties
The IRS appears willing to assert both civil fraud penalties and alternative economic substance penalties in the same case when large Puerto Rico exclusion claims are involved.
The petition highlights how residency determinations can affect downstream international tax treatment. If the taxpayer loses Puerto Rico residency status, multiple Puerto Rico entities could become controlled foreign corporations subject to Subpart F and GILTI inclusion rules.
Key Facts
Karakashian alleges that he became a permanent resident of Puerto Rico in 2018 and remained a bona fide resident through 2021.
He claims:
209 days of Puerto Rico presence during 2021
a Puerto Rico tax home
minimal U.S. personal connections
The taxpayer operated or owned several entities, including:
Tripod Management Services, LLC
Aqua Investments, LLC
Zeus Protected Cell
Gary V. Karakashian International Business Group, Inc.
Gary V. Karakashian, M.D., P.A.
The petition states that Tripod provided physician, administrative, telehealth, pathology, billing, compliance, and management services from Puerto Rico to a New Jersey dermatology practice.
The IRS also challenged:
more than $4 million of allegedly excluded capital gains
deductions tied to captive insurance premiums
depreciation and business expense deductions
investment interest expense
additional “other income” reconstructed using bank deposit methods
Statutory Framework
Section 937(a) defines a bona fide Puerto Rico resident using three principal tests:
Physical presence test
Tax home test
Closer connection test
Section 933 generally excludes Puerto Rico source income from U.S. federal income tax for bona fide Puerto Rico residents.
Sections 951 and 951A govern Subpart F and GILTI inclusions for U.S. shareholders of controlled foreign corporations.
Section 6663 imposes a 75% civil fraud penalty on underpayments attributable to fraud.
Section 6662 includes accuracy-related penalties for:
negligence
substantial understatement
non-economic substance transactions
undisclosed foreign financial asset understatements
Taxpayer Argued
He satisfied all Puerto Rico residency tests under §937(a).
Puerto Rico source income was properly excluded under §933.
Puerto Rico entities were not controlled foreign corporations because they were bona fide residents of Puerto Rico.
Captive insurance arrangements constituted valid insurance transactions with economic substance.
Premiums were actuarially determined and supported by risk distribution arrangements through a Puerto Rico reinsurance pool.
Business deductions and depreciation were properly substantiated.
He relied on qualified professional advisors and did not commit fraud.
Government Argued
According to the petition, the IRS concluded:
the taxpayer failed Puerto Rico residency requirements
Puerto Rico income exclusions were improper
Puerto Rico entities constituted controlled foreign corporations
certain income was subject to Subpart F and GILTI inclusion
captive insurance arrangements failed federal tax requirements
various deductions lacked substantiation or represented personal expenses
fraud or alternative accuracy-related penalties applied
Court Process and Issues to Watch
The petition raises several issues that frequently appear in modern Puerto Rico enforcement cases.
Residency documentation
The taxpayer claims 209 qualifying Puerto Rico days, including days attributable to medical treatment exceptions. The IRS often scrutinizes:
travel logs
phone records
flight data
utility usage
social connections
business activity location
Captive insurance scrutiny
The petition describes a sophisticated captive insurance structure involving:
protected cell arrangements
actuarial studies
reinsurance participation
Puerto Rico insurance regulation
risk distribution mechanisms
The IRS has aggressively challenged micro-captive and related insurance structures for years, especially where tax benefits substantially outweigh demonstrated insurance purpose.
Puerto Rico management company structures
The petition claims the taxpayer personally performed management and telehealth services from Puerto Rico through Tripod.
That issue matters because service income sourcing and operational substance remain central in Puerto Rico residency examinations.
Economic substance penalties
The IRS asserted fraud penalties and, alternatively, non-economic substance penalties.
That approach gives the government multiple fallback positions if fraud is difficult to prove. Tax litigation increasingly resembles a prosecutor carrying backup batteries because modern tax structures tend to fail in layers rather than all at once.
The Takeaway
This petition shows that Puerto Rico residency disputes often grow to include international tax, captive insurance, transfer pricing, and economic substance issues once the IRS questions residency.
For practitioners, the key point is both procedural and substantive: losing a Puerto Rico residency claim can cause a chain reaction across entity classification, Subpart F exposure, reporting, sourcing rules, and penalties. One residency decision can reopen an entire structure.
