Tax Incentives & Special Economic Zones

Regulator-Grade Guidance Document

Date: June 2026 Domain: Digital Asset Taxation Section: Tax Incentives, Special Zones & De Minimis Thresholds Audience: Tax authorities, economic-development officials, policy designers Coverage: All 19 jurisdictions in the matrix

1. Types of Tax Incentives for Digital Assets

Across the 19 jurisdictions analysed, incentive design clusters into five principal mechanisms: zero/low income-tax regimes, holding-period exemptions, special economic zones, R&D/innovation credits, and targeted time-limited exemptions. A parallel "soft incentive" layer — de minimis thresholds, filing thresholds, and small-disposal exemptions — operates in most jurisdictions even where no headline incentive exists. This section catalogues each mechanism with verified examples drawn directly from the per-jurisdiction matrix.

A structural observation frames the whole section: only a minority of jurisdictions offer affirmative crypto incentives at all. Of the 19, eight have no notable incentive (the US offers only a general charitable-donation rule; Brazil, Canada, India, Nigeria, South Africa, South Korea, and the EU as a bloc have none crypto-specific). The incentive landscape is therefore concentrated, and the "race to the bottom" narrative overstates how many jurisdictions actually compete on tax.

1.1 Zero/Low Income Tax (

UAE,

El Salvador,

Singapore)

Zero personal income tax on crypto gains is the most aggressive incentive model. Three jurisdictions in the matrix exemplify variants of this approach:

UAE: The UAE imposes no personal income tax on any form of individual income, including crypto trading profits, staking rewards, and capital gains — its effective maximum individual rate on crypto is 0%. This is not a crypto-specific incentive but a structural feature of the UAE's tax system. Corporate entities face a 9% federal corporate tax on profits exceeding AED 375,000 (Federal Decree-Law No. 47 of 2022, effective June 2023), but Qualifying Free Zone Persons (QFZPs) can access a 0% rate on Qualifying Income (see Section 1.3). Cabinet Decision No. 100 of 2024 (effective 15 November 2024) retroactively exempted the transfer, conversion, and custody of virtual assets from VAT back to 1 January 2018.

El Salvador: Under Article 5 of Decree No. 57/2021 (the Bitcoin Law), Bitcoin disposals — including crypto-to-crypto and crypto-to-fiat conversions — are exempt from capital gains tax with no minimum holding period and no cap on the exempt amount. CNAD-licensed digital-asset businesses benefit from 0% corporate tax on digital-asset income and VAT exemption on digital-asset transfers. El Salvador also imposes no exit, wealth, or inheritance tax, removed all taxes related to technology innovation in 2025, and offers a USD 1 million investment pathway to residency/citizenship. The standard 30% corporate income tax applies only to non-crypto business income. (Note: reports of a "3 BTC threshold for tax relief" are NOT VERIFIED and are not relied upon here.)

Singapore: Singapore has no capital gains tax (a longstanding structural feature, not a crypto-specific measure), so capital-nature gains on digital payment tokens (DPTs) are untaxed at 0%. Only habitual/professional traders are taxed — as business income at progressive individual rates (0–24%) or 17% corporate. DPT supplies have been GST-exempt since 1 January 2020. The matrix also records a fresh corporate incentive: the IRAS enhanced the YA 2026 Corporate Income Tax Rebate to 50% of tax payable (capped at SGD 40,000) following the 7 April 2026 announcement (up from the 40% rebate introduced in Budget 2026 on 12 February 2026), with a SGD 2,000 CIT Rebate Cash Grant. This is general, not crypto-specific, but benefits resident crypto firms.

Other structural no-tax features (non-incentive but tax-favourable):

Switzerland exempts private capital gains entirely (0%) for individuals who are not professional traders, and the matrix does not record income/capital-gains tax for individual crypto disposals in several other low-tax contexts. These are treated as structural features rather than discretionary incentives.

1.2 Holding Period Exemptions (

Germany,

Portugal)

Holding-period exemptions provide full tax exemption on crypto gains after a specified duration, while taxing short-term speculative trades. This represents a deliberate policy choice to encourage long-term investment over short-term speculation. Of the 19 jurisdictions, two operate true holding-period exemptions; several others (US, Australia) grant rate discounts rather than full exemptions.

Germany: Under the private-disposal rules of the Income Tax Act (EStG §23), gains on crypto held for more than 12 months are entirely tax-free; the 1-year exemption is listed in the matrix as "one of [the] most favorable in [the] EU." Short-term gains (under 12 months) face the individual's marginal rate of 14–45% plus a 5.5% solidarity surcharge. A Freigrenze (all-or-nothing exemption limit) of EUR 1,000/year applies from 2024 (up from EUR 600) — meaning the entire amount becomes taxable if exceeded by even EUR 1. The BMF Circular of 6 March 2025 confirmed that staking does not extend the holding period and provided first-ever DeFi guidance. Per-wallet FIFO is permitted, enabling optimisation.

Portugal: Since 1 January 2023, gains from disposal of crypto held for 365 days or more are exempt; short-term gains (<365 days) face a flat 28% rate (35% if linked to a tax-haven/blacklisted jurisdiction). Crypto-to-crypto swaps are explicitly non-taxable, mining benefits from a simplified regime (only 15% of gross income taxable — the 0.15 coefficient), and in-kind staking rewards are not taxed until conversion to fiat. Critically, NFT income is expressly excluded from the crypto tax regime (effectively 0%), a rare affirmative carve-out.

Rate-discount variants (not full exemptions):

• United States: assets held >1 year qualify for preferential long-term capital-gains rates of 0%/15%/20% (vs ordinary 10–37%). For 2026 the 20% top long-term bracket begins at USD 613,700 for married-filing-jointly (MFJ); the effective maximum is 23.8% with the 3.8% NIIT.
• Australia: a 50% CGT discount for individuals holding >12 months (~23.5% effective long-term vs 47% short-term).

1.3 Special Economic Zones (

UAE ADGM/DIFC/DMCC,

Switzerland Zug,

Thailand)

Special Economic Zones (SEZs) and free zones offer regulatory and tax advantages within defined geographic or legal boundaries. The matrix identifies genuine crypto-relevant zones in only three jurisdictions.

UAE Free Zones (ADGM, DIFC, DMCC): Qualifying Free Zone Persons in Abu Dhabi Global Market (ADGM, regulated by FSRA), Dubai International Financial Centre (DIFC, regulated by DFSA), and Dubai Multi Commodities Centre (DMCC) are eligible for a 0% corporate tax rate on Qualifying Income for a guaranteed period (typically 50 years for ADGM/DIFC), subject to substance and activity tests. Requirements include adequate employees, expenditure, and assets in the zone; core income-generating activities directed from the zone; mainland revenue within the de minimis threshold; and transfer-pricing/arm's-length compliance. A critical enforcement mechanism applies: loss of QFZP status triggers retroactive 9% taxation for the current and up to four subsequent tax periods. The matrix records over 2,500 VARA licence applications as of 2025.

Switzerland — Zug ("Crypto Valley"): Canton Zug competes via low cantonal/municipal rates, the private capital-gains exemption, the lowest wealth-tax rates, and a technology-neutral approach. Zug is the matrix-named special zone; cantonal competition rather than a statutory SEZ drives the advantage.

Thailand — Digital Asset Hub: Thailand's incentive is a Digital Asset Hub strategy layered on a special-zone-style sandbox: the TouristDigiPay 18-month sandbox launched in Q4 2025 (crypto-to-baht for tourist spending), alongside the LTR-visa foreign-sourced-income exemption. The headline tax incentive is the 5-year exemption (Section 1.5).

No other jurisdiction in the matrix records a crypto-specific special economic zone: the EU has none at EU level; Canada's "Quebec mining energy rates (Hydro-Québec)" are explicitly not a tax incentive; El Salvador promotes geothermal (volcano) Bitcoin mining and 2025 tech-innovation tax removal but no formal SEZ; the US, India, Nigeria, South Africa, South Korea, Australia, Japan, France, the UK, and Portugal record no special zone (Portugal's NHR closed to new applicants on 1 January 2024, replaced by IFICI/NHR 2.0, which does not cover crypto gains/staking).

1.4 R&D/Innovation Tax Credits & Innovation Hubs

Several jurisdictions offer innovation incentives applicable to blockchain development, though few are crypto-specific:

United States: The matrix records the principal US incentive as a charitable-donation rule — donating crypto held >1 year is deductible at fair market value without recognising gain — rather than a crypto R&D credit. (General federal R&D credits exist but are not in the matrix's t7 incentives field.)

Singapore: Beyond the structural no-CGT regime, Singapore's general innovation framework and the YA 2026 CIT Rebate (Section 1.1) provide broad-based relief; no crypto-specific R&D incentive is recorded.

Japan: Japan's matrix incentive is corporate-focused: the corporate unrealized-gains tax on token holdings was abolished (FY2024, all tokens, from 1 April 2024), a material relief for token-issuing companies and treasuries. Japan also pursues Web3 hub initiatives (FinCity.Tokyo; the LDP Web3.0 Working Group), with 200+ Web3 startups in 2025. A proposed flat 20.315% separate taxation with 3-year loss carryforward for specified crypto assets is proposed/not enacted (contingent on FIEA reclassification).

1.5 Targeted, Time-Limited Exemptions (

Thailand 5-Year CG Exemption)

Targeted, time-limited exemptions are a middle path between permanent zero-tax regimes and standard taxation.

Thailand: Ministerial Regulation No. 399 (B.E. 2568), published in the Royal Gazette on 5 September 2025 (Cabinet-approved 17 June 2025), provides a five-year personal income tax exemption on capital gains from crypto trading through SEC-licensed platforms (1 January 2025 – 31 December 2029). Key design features:

• Only transactions through SEC-licensed exchanges, brokers, or dealers qualify
• Individuals only — corporate entities remain subject to the standard 20% corporate income tax
• Does not cover mining, staking, DeFi, airdrops, or P2P transactions
• VAT exemption on transfers through SEC-licensed operators continues under Royal Decree No. 744 (B.E. 2565/2022)

The exemption replaces the prior 15% withholding tax on crypto capital gains, repositioning Thailand as a "Digital Asset Hub" in competition with

Singapore and Hong Kong. Renewal beyond 2029 is uncertain.

South Korea — deferral as de facto incentive: Crypto gains remain untaxed for individuals until the 22% tax (20% + 2% local) takes effect on 1 January 2027. The repeated deferral has functioned as an unintended time-limited incentive. Separately, the FSC lifted its nine-year corporate crypto-holding ban on 11 January 2026 (allowing up to 5% of equity capital in top-20 cryptos), a structural liberalisation rather than a tax incentive.

2. De Minimis Thresholds & Small-Disposal Exemptions

A defining feature of the refreshed matrix is the prevalence of de minimis and small-disposal exemptions even where no headline incentive exists. These thresholds shape effective tax burdens for retail investors more than marginal rates do. The following table mirrors the t7 de_minimis field across all 19 jurisdictions.

Design insight: the most consequential thresholds are Brazil's monthly R$35,000 disposal exemption (which removes the bulk of retail traders from CGT entirely), the UK's GBP 3,000 Annual Exempt Amount, South Africa's R50,000 exclusion, and South Korea's incoming KRW 2.5m threshold. Germany's EUR 1,000 Freigrenze is the cautionary case: its all-or-nothing cliff means EUR 1,001 in gains makes the entire amount taxable.

3. Comparative Table — Headline Incentives Across All 19

4. Effectiveness Assessment

4.1 Revenue Impact

Tax incentives create a tension between foregone revenue and indirect economic benefits. The evidence across the matrix is mixed:

Revenue-positive or revenue-neutral outcomes:

• The
  UAE's zero personal tax is part of a broader model where revenue comes from VAT (5%), the 9% corporate tax, free-zone fees, and the 5% VAT on crypto mining (VATP039, January 2025) and platform services.
• Singapore's approach taxes professional/trading income (up to 24% individual / 17% corporate) while exempting capital-nature gains — capturing revenue from the professional ecosystem while attracting individual capital.
• Thailand's exemption is designed to increase licensed-platform activity, channelling volume toward SEC-licensed venues that are subject to corporate tax and VAT.

Revenue-negative or ambiguous outcomes:

• El Salvador's Bitcoin experiment has been characterised by the IMF as posing fiscal risks. Under the 40-month EFF (~US$1.4 billion, approved 26 February 2025), Bitcoin acceptance became voluntary and tax can no longer be paid in Bitcoin (USD only) — but the core 0% Bitcoin CGT and the CNAD DASP 0% corporate/VAT-exempt regime remain in force (confirmed Q2 2026).
• Permanent structural zero-tax (UAE personal, Singapore CGT, Switzerland private CGT) forgoes direct revenue from the asset class entirely, sustainable only where the broader economic model supports it.

4.2 Business Attraction

The matrix supports a correlation between favourable treatment and business clustering:

• UAE: over 2,500 VARA licence applications as of 2025; multi-regulator framework (VARA, FSRA, DFSA, federal CMA) providing institutional-grade certainty.
• Singapore: the 30 June 2025 compliance deadline for licensed platforms and the DTSP licensing regime (FSMA 2022, from mid-2025) signal a "permissive but well-regulated" posture; no capital gains tax remains the core draw.
• Japan: 200+ Web3 startups in 2025 and the FY2024 abolition of corporate unrealized-gains tax have improved competitiveness for token issuers, though the ~55% individual rate remains a deterrent pending the proposed 2027 reform.
• Switzerland: Zug's private capital-gains exemption and low wealth tax sustain "Crypto Valley" clustering.

The CoinCub-style observation that "the era of no tax and no reporting is quickly coming to an end" is borne out by the CARF/DAC8 rollout (Section 4.4): tax rates alone are becoming less decisive than regulatory clarity, reporting infrastructure, and institutional access.

4.3 Brain Drain Effects

Tax-driven migration creates distributional effects visible in the matrix:

• Winners: the UAE (0% personal), Singapore (0% CGT), and Switzerland (private-gains exemption) attract talent and capital through favourable treatment combined with regulatory infrastructure.
• Losers: higher-tax jurisdictions —
  India (30% flat + 1% TDS, up to 42.74%),
  Japan (~55.945% current), and high-bracket EU states — face outflows.
• Transition cases:
  Portugal's shift from a de facto 0% regime (pre-2023) to 28% short-term (with 365-day exemption) reduced headline attractiveness, compounded by the NHR closure on 1 January 2024; it remains favourable for buy-and-hold.

4.4 Race to the Bottom — Constrained by CARF/DAC8

The "race to the bottom" concern is real but increasingly constrained by international coordination. Of the 19 jurisdictions, 18 have committed to or implemented the OECD Crypto-Asset Reporting Framework (CARF); only El Salvador has not (it remains one of a small set of non-committed "relevant" jurisdictions). The first-exchange timelines below are taken directly from the refreshed matrix and supersede earlier estimates.

CARF first-exchange year by jurisdiction (from the matrix):

Key facts mirrored from the matrix:

• EU DAC8 (Council Directive (EU) 2023/2226) went live 1 January 2026, with the first automatic exchange by 30 September 2027 (first reporting year: calendar 2026). The Commission launched infringement proceedings against 12 member states for missed transposition on 30 January 2026.
• Germany transposed DAC8/CARF via the KryptoStTranspG (KStTG), in force 1 January 2026; first international exchange by 30 September 2027.
• Portugal transposed DAC8/CARF by Law No. 26/2026 of 3 June 2026; first AT report due 31 May 2027; first exchange in 2027.
• Switzerland is the EU/early-adopter outlier: its CARF crypto provisions do not apply in 2026 (deferred to 2027+), with first automatic exchange expected ~2028.
• UAE signed the CARF MCAA on 20 September 2025 (MoF announcement; MCAA dated 21 July 2025 on the OECD list), with go-live 1 January 2027 and first exchange in 2028.
• Nigeria committed in November 2024, with CARF-aligned CASP procedures required by 1 January 2028 (not the 2027 first-mover cohort).
• Japan is an early adopter: CARF took effect 1 January 2026, first RCASP reports due 30 April 2027.

OECD Pillar Two: the 15% global minimum corporate tax (MNE groups with EUR 750M+ revenue) constrains large-scale corporate arbitrage; Portugal's Law No. 26/2026 also transposes DAC9/Pillar Two.

5. Case Studies

5.1

UAE: The Zero-Tax Magnet — Now CARF-Bound

The UAE offers the matrix's most comprehensive tax-advantage package:

1. Zero personal income tax on all crypto gains (structural, effective max individual rate 0%)
2. 0% corporate tax for QFZPs (ADGM, DIFC, DMCC) on Qualifying Income for up to ~50 years
3. Retroactive VAT exemption on crypto transfers, conversions, and custody (Cabinet Decision 100/2024, back to 2018)
4. Multi-regulator framework (federal CMA, VARA, FSRA, DFSA) providing institutional-grade certainty

The catch — it is not truly "zero tax" for businesses:

• 9% corporate tax on non-QFZP business income above AED 375,000
• QFZP status requires genuine substance; loss of status triggers retroactive 9% taxation for up to five tax periods
• Mining is subject to 5% VAT (FTA Guidance VATP039, January 2025)
• Individuals must register for corporate tax if crypto activity resembles a business and exceeds AED 1,000,000 annual revenue

CARF correction: the UAE signed the CARF MCAA in September 2025, with go-live 1 January 2027 and first automatic exchange in 2028 (covering the 2027 reporting year). This will materially increase transparency, reducing the advantage for individuals seeking to avoid home-country taxation.

5.2

Portugal: From 0% to a Durable 365-Day Model

Before 2023: Portugal taxed individual crypto disposals only nominally — a de facto 0% regime — combined with the NHR regime, making it a premier destination for crypto investors and digital nomads.

The 2023 shift: the 2023 State Budget introduced, effective 1 January 2023, a 28% flat rate on short-term gains (<365 days), 0% on long-term gains (365+ days), crypto-to-crypto non-taxability, and a simplified mining regime (15% of gross taxable).

The durable design: the combination of short-term taxation with long-term exemption, plus the express exclusion of NFT income from the crypto regime, has preserved Portugal's appeal for buy-and-hold investors even as EU harmonisation (MiCAR via Law No. 69/2025; DAC8/CARF via Law No. 26/2026) advances. The NHR closure on 1 January 2024 (replaced by the narrower IFICI/NHR 2.0, which does not cover crypto investors) was a larger blow to expat investors than the 28% rate itself.

Key lesson: unstructured 0% regimes are inherently unstable; a holding-period exemption paired with short-term taxation is the more durable design.

5.3

Thailand: Conditioning the Incentive on Licensing

Thailand's 5-year exemption (2025–2029) is the matrix's clearest example of conditioning an incentive on regulatory compliance:

• The exemption applies only to trades through SEC-licensed exchanges, brokers, or dealers — channelling activity toward regulated, monitored venues.
• It covers individuals only; corporates remain at the 20% corporate rate.
• It explicitly excludes mining, staking, DeFi, airdrops, and P2P transactions.
• It is paired with a Digital Asset Hub strategy and the TouristDigiPay sandbox (Q4 2025).

By design, the incentive increases tax-authority visibility while reducing the tax burden — the opposite of a secrecy-driven haven. Renewal beyond 31 December 2029 is uncertain, and CARF first-exchange (2028) will further increase transparency.

5.4

El Salvador: The Most Favourable Regime, Now CARF-Absent

El Salvador's Bitcoin experiment (Decree No. 57/2021) remains the matrix's most favourable tax regime:

• 0% Bitcoin CGT (no holding period, no cap), 0% corporate tax for CNAD-licensed digital-asset income, VAT exemption
• No exit, wealth, or inheritance tax; USD 1 million investment residency/citizenship pathway
• Geothermal (Tecapa volcano) mining promotion; 2025 tech-innovation tax removal

The constraints: under the IMF EFF (approved 26 February 2025; first review June 2025; second review ongoing as of December 2025), Bitcoin acceptance became voluntary and tax is no longer payable in Bitcoin (USD only), and the Chivo wallet is being unwound. The core 0% Bitcoin CGT and CNAD DASP regime survived and remain in force (confirmed Q2 2026). Critically, El Salvador is the only matrix jurisdiction not committed to CARF, leaving no automatic exchange of Salvadoran CASP data — a transparency gap that distinguishes it sharply from every other incentive jurisdiction.

Key lesson: tax incentives alone are insufficient; institutional infrastructure, regulatory maturity, and macroeconomic stability are prerequisites — and CARF non-participation increasingly marks a jurisdiction as an outlier rather than a competitor.

6. What Works and What Doesn't

What Works

1. Holding-period exemptions (
   Germany 12-month,
   Portugal 365-day): binary, low-compliance rules that reward long-term holding while capturing short-term speculation. CARF-compatible.
2. Structural no-CGT regimes with robust regulation (
   Singapore,
   UAE,
   Switzerland private gains): zero capital-gains tax paired with comprehensive licensing (MAS; VARA/FSRA/DFSA; FINMA safe-harbour criteria) attracts both individuals and institutions.
3. Free-zone/SEZ models with substance requirements (
   UAE ADGM/DIFC/DMCC): concentrate activity within supervised zones while requiring genuine economic substance; the QFZP five-period penalty is the benchmark enforcement mechanism.
4. Targeted, time-limited exemptions conditioned on licensing (
   Thailand): channel activity toward regulated exchanges, increasing transparency while reducing the tax burden.
5. Well-calibrated de minimis thresholds (
   UK GBP 3,000,
   Brazil R$35,000/month,
   South Africa R50,000): remove retail traders from the net without creating havens — provided the threshold is not an all-or-nothing cliff.
6. Corporate liberalisations (
   Japan unrealized-gains abolition;
   South Korea corporate-holding-ban lift): improve treasury/issuer competitiveness without blanket exemptions.

What Doesn't Work

1. Blanket zero-tax with weak institutions or no transparency (
   El Salvador): without regulatory depth and CARF participation, the incentive becomes a marketing tool rather than a development driver.
2. Unstable/unstructured 0% regimes (
   Portugal pre-2023): de facto zero-tax via regulatory omission is inherently temporary; closing the gap is disruptive.
3. Punitive treatment as a deterrent (
   India 30% + 1% TDS;
   Japan ~55% current): drives business and talent offshore — counter-examples demonstrating the cost of punitive design.
4. All-or-nothing de minimis cliffs (
   Germany EUR 1,000 Freigrenze): EUR 1,001 in gains makes the entire amount taxable — a poorly designed threshold that distorts behaviour at the margin.
5. Incentives without CARF/transparency alignment: "0% no longer means invisible." With 18 of 19 jurisdictions on CARF, offering incentives outside the transparency regime invites reputational and counterparty risk.

7. Recommended Framework

Based on the 19 jurisdictions analysed:

Principle 1: Distinguish Investment from Business Activity

Exempt or reduce taxation on long-term investment gains while taxing professional/business activity at standard rates.

Singapore's "badges of trade" model and

Switzerland's five safe-harbour criteria are tested frameworks.

Principle 2: Prefer Holding-Period Exemptions Over Blanket Zero-Tax

A 12-month holding-period exemption (the

Germany model) or 365-day model (the

Portugal model) is more defensible than blanket zero-tax — it captures speculation, encourages patient capital, and is CARF-compatible.

Principle 3: Condition Incentives on Regulatory Compliance

Thailand's conditioning of the exemption on SEC-licensed platform use is a powerful pattern: it channels activity toward regulated venues and can be withdrawn if compliance deteriorates.

Principle 4: Ensure Genuine Economic Substance for Zone Benefits

Free-zone benefits must be conditioned on substance — employees, expenditure, assets in the zone. The

UAE QFZP model with its five-period penalty for non-compliance is the benchmark.

Principle 5: Design De Minimis Thresholds as Allowances, Not Cliffs

UK's GBP 3,000 Annual Exempt Amount and

South Africa's R50,000 exclusion taper sensibly;

Germany's all-or-nothing Freigrenze is the design to avoid.

Principle 6: Adopt CARF and International Transparency Standards

Any incentive regime should be paired with CARF adoption. With 18 of 19 matrix jurisdictions committed or implemented, CARF is the emerging global floor —

El Salvador's non-participation is now the conspicuous exception.

Principle 7: Design for Durability and Provide Clear Guidance

Permanent structural features (

Germany holding period,

Singapore no-CGT) outperform temporary measures; time-limited incentives (

Thailand's 5-year model) should include clear evaluation/extension criteria. Detailed published guidance (Germany's BMF circulars, Singapore's IRAS e-Tax Guides, Thailand's Ministerial Regulation No. 399) attracts business as effectively as low rates.

Verification Notes

This document is a refresh synthesis dated 4 June 2026. It mirrors the canonical per-jurisdiction facts in .claude/digital-asset-taxation-fact-matrix.json (the verified source of truth) across all 19 jurisdictions and introduces no fact not present in that matrix. No web search or external fetching was performed in this refresh; where the matrix records a fact as "NOT VERIFIED," that status is reflected honestly (e.g. El Salvador's reported "3 BTC threshold," UAE/Nigeria/South Africa stablecoin and travel-rule fields).

Corrections applied in this pass (vs the prior March 2026 version):

1. CARF first-exchange years re-derived directly from each jurisdiction's carf_first_exchange_year field. The prior "52 by 2027 / 15 by 2028" generic figures are replaced with the matrix's per-jurisdiction timelines: 2027 cohort (Brazil, Canada, India, Japan, South Korea, EU, France, Germany, Portugal, South Africa, UK); US on a longer 2027–2029 timeline; 2028 cohort (Australia, Singapore, Thailand, Nigeria, UAE, Switzerland ~2028); El Salvador not participating.
2. CARF/transparency aggregate recomputed: 18 of 19 jurisdictions committed or implemented; 1 of 19 (El Salvador) not committed.
3. Incentive aggregate recomputed: of 19, eight have no notable crypto incentive (US has only the charitable-donation rule; Brazil, Canada, India, Nigeria, South Africa, South Korea, and the EU bloc record none crypto-specific).
4. UAE CARF detail corrected: MCAA signed September 2025; go-live 1 January 2027; first exchange 2028.
5. Brazil MP 1303/2025 (flat 17.5%) recorded as EXPIRED (withdrawn/sem eficácia 8 October 2025); progressive 15–22.5% rates and the R$35,000 monthly exemption restored in full — reflected in the de minimis table.
6. US 2026 long-term capital-gains 20% breakpoint stated as USD 613,700 (MFJ).
7. Nigeria framework attributed to NTAA 2025 (effective 1 January 2026); de minimis (N800,000 at 0%) mirrored.
8. South Africa R50,000 annual CGT exclusion (raised from R40,000, from 1 March 2026) mirrored.
9. Thailand, Germany, Portugal, Singapore, and Japan incentive/zone/de-minimis fields mirrored from t7; Portugal NHR→IFICI and Japan corporate unrealized-gains abolition added.
10. Region values map to the canonical five-region set (Americas, Asia-Pacific, Europe, Middle-East-Africa, plus the EU/international layer); tags limited to canonical type/guidance and dimension/tax-incentives.
