The leaked tapes that show how the rich avoid taxes

What It Covers

Planet Money traces the full lifecycle of the Malta pension loophole — how tax lawyers exploited a 2008 US-Malta tax treaty to shelter billions in capital gains, how the IRS fought to close it via the "dirty dozen" list and a proposed disclosure rule, and how the effort stalled under the Trump administration.

Key Questions Answered

• •Loophole anatomy: Tax loopholes often emerge from ambiguous treaty language, not deliberate fraud. The US-Malta Tax Treaty of 2008 left retirement account rules undefined, allowing lawyers to argue Americans could deposit unlimited appreciated assets — real estate, company stakes, Bitcoin — into Maltese accounts and withdraw proceeds tax-free starting at age 50.
• •Economic substance doctrine: The IRS uses a legal test called the "economic substance doctrine" to distinguish legitimate tax planning from abusive shelters. If a financial structure has no logical business purpose beyond avoiding taxes — as with Maltese pension accounts for US residents — it fails this test and becomes legally vulnerable in tax court.
• •Loophole as wasting asset: Tax professionals who discover loopholes face a strategic clock. Publishing articles about the Malta scheme in law journals signaled genuine belief in its legality but also alerted the IRS. Practitioners estimated a limited window to maximize use before government closure, with hundreds of taxpayers moving an estimated billions of dollars into these accounts.
• •Treaty modification as enforcement tool: Rather than lengthy legislation, the IRS closed the Malta loophole by negotiating directly with Maltese officials in late 2021 to issue a joint clarifying statement. This reinterpretation — limiting deposits to already-taxed cash, not appreciated assets — took less than one year from initial identification to formal treaty clarification.
• •Regulatory vulnerability: A proposed IRS "come clean" rule requiring Malta pension participants to self-disclose and pay owed taxes never became finalized. Political transitions, DOGE-driven IRS staff reductions, and the appointment of a former Malta-loophole lobbyist, Kenneth Keyes, as acting IRS chief counsel effectively halted enforcement momentum before the rule reached the federal register.
