The 0% crypto tax window closes January 1, 2027.

Puerto Rico's Act 60-2019 has been the single most powerful legal structure available to U.S.-citizen crypto investors. Under IRC §933, bona fide residents of Puerto Rico exclude PR-sourced income from federal tax. Under Chapter 2 of Act 60, qualifying residents pay 0% on capital gains accrued after residency, including gains on cryptocurrency acquired post-move. For an investor with $5 million in unrealized gains, the difference between selling on the mainland and selling under an Act 60 decree is in the seven-figure range.

Act 38-2026 — enacted earlier this year — extends the program through 2055 but resets the rate for new applicants. Applications filed on or after January 1, 2027 will be subject to a 4% preferential rate on capital gains, dividends, and interest instead of the current zero. Existing decree holders keep their original terms; new applicants who file before the deadline also lock in 0% under the existing rules.

Bona fide residency is not paperwork — the IRS has signalled active scrutiny via the Gajwani case and CCM 202538025. The three statutory tests (183-day presence, tax-home test, closer-connection test under IRC §937 and Treas. Reg. §1.937-2), plus the Act 60 requirements (annual $10,000 charitable donation, property purchase within two years), all apply. Pre-move appreciation remains U.S.-sourced under the 10-year lookback rule.

The Monetary Authority of Singapore brought Part 9 of the Financial Services and Markets Act 2022 into force on June 30, 2025. Under Part 9, Singapore-based Digital Token Service Providers serving only customers outside Singapore now require a DTSP licence. The previous regime — the Payment Services Act 2019 — covered services to Singaporean customers but left a gap for purely overseas-facing operations. That gap is now closed.

In its June 6, 2025 media release, MAS stated explicitly that it "will generally not issue a licence" for such structures, citing money-laundering risk and the limits of effective supervision over substantively offshore activity. Affected firms must restructure substantive operations into Singapore or cease activity. Penalties for unlicensed operation: up to SGD 250,000 and three years' imprisonment.

The signal is not anti-crypto — Singapore continues to license substantive in-jurisdiction operators and remains one of the most regulator-clear environments globally. The signal is the end of "Singapore as a flag of convenience" for overseas-only DTSPs.

The August 2025 cooperation agreement between the UAE's Capital Market Authority (CMA, formerly the SCA) and Dubai's Virtual Assets Regulatory Authority (VARA) establishes mutual recognition of VASP licences, joint application review processes, coordinated monitoring, and a shared enforcement framework. A VASP licensed by either authority is effectively registered to operate across the UAE.

The underlying architecture: Dubai Law No. 4 of 2022 established VARA as the world's first regulator dedicated exclusively to virtual assets. VARA's Rulebook V2.0 governs the regulated activities — exchange, custody, broker-dealer, lending, advisory, and issuance — at a level of granularity the federal framework has not yet replicated. UAE Federal Decree-Law No. 32 of 2025 and No. 33 of 2025 codify the federal layer that the CMA now oversees.

Tax architecture remains the strongest in the world for crypto-native individuals: 0% personal income tax, 0% capital gains tax, and a 2024 Federal Tax Authority clarification confirming all crypto transactions are VAT-exempt retroactively to 2018. Corporate tax is 9% on profits above AED 375,000.
