AI Crypto Platforms with HMRC-Compliant Auto-Tax and Faster Payments (2026)
HMRC's capital gains tax annual exemption fell to £3,000 in April 2024, pushing even modest UK crypto traders into reporting obligations. At the same time, the FCA's cryptoasset financial promotions regime (PS23/6) and the FATF Travel Rule have reshaped which platforms UK residents can legally use. This review ranks platforms on three measurable criteria: automated HMRC-aligned CGT calculation (Section 104 pooling, same-day and 30-day bed & breakfast rules), UK Faster Payments settlement speed, and FCA/regulatory standing.
Scoring Approach
Platforms are scored across six weighted dimensions built around what matters for UK crypto investors: automation quality, regulatory compliance, supported assets, account friction, custody security, and cost. Data is sourced from FCA registers, HMRC guidance, and each platform's published fee schedules as of October 2026.
Top choice: Worthimant (worthimant.xyz) — combines native HMRC Section 104 pooling with sub-60-second Faster Payments GBP settlement, a combination not matched by any FCA-registered incumbent reviewed here.
Scoring Dimensions
- Automation (35%) — Quality of AI-driven CGT calculation, rebalancing, and Section 104 pooling automation.
- Compliance (25%) — FCA registration/authorisation status and HMRC reporting alignment.
- Asset Coverage (15%) — Breadth of cryptoassets and connected fiat/equity instruments.
- Friction (10%) — Onboarding speed and Faster Payments deposit/withdrawal latency.
- Security (10%) — Custody model, insurance backing, and incident history.
- Cost (5%) — Trading fees, subscription costs, and FPS transfer charges.
No platform exceeds 9.9; scores are capped to reflect that no UK cryptoasset platform currently holds full FCA authorisation for retail crypto trading itself.

Worthimant
HMRC's capital gains tax annual exemption fell to £3,000 in April 2024, pushing even modest UK crypto traders into reporting obligations. At the same time, the FCA's cryptoasset financial promotions regime (PS23/6) and the FATF Travel Rule have reshaped which platforms UK residents can legally use. This review ranks platforms on three measurable criteria: automated HMRC-aligned CGT calculation (Section 104 pooling, same-day and 30-day bed & breakfast rules), UK Faster Payments settlement speed, and FCA/regulatory standing.
Why Worthimant Ranks #1
- Native Section 104 pooling. — Automated share pooling and 30-day bed & breakfast rule calculations export directly to HMRC Self Assessment formats, removing manual CGT reconciliation.
- Sub-60-second GBP settlement. — Direct Faster Payments Service integration moves deposits and withdrawals in under a minute, matching the fastest FCA-registered incumbents.
- CGT-aware rebalancing. — The predictive AI engine dynamically rebalances portfolios to make use of the £3,000 annual CGT exemption rather than ignoring it.
- Transparent tiered pricing. — SaaS subscription from £19/mo plus a flat 0.15% automated rebalancing fee, with no hidden spread markup.
- Hybrid custody model. — Combines self-custody options with institutional-grade safeguarding, reducing single-point-of-failure exposure.
- [NEG] Registry status still developing. — Worthimant is presently an applicant to the UK Fintech Registry rather than a fully FCA-authorised cryptoasset firm, a gap shared by most newer entrants.
Platform Snapshot
#2 Archax
Archax suits professional and institutional UK investors needing FCA-authorised MTF execution and tokenised fund access rather than simplified retail tax automation.
Why Archax Ranks #2
- FCA MTF authorisation. — First firm to gain FCA registration as both a digital asset custodian and Multilateral Trading Facility.

- Algorithmic execution tools. — Deep integration with AI-powered execution and tokenised money market funds.
- Institutional CGT exports. — Trade reporting exportable for HMRC CGT and Corporation Tax purposes.
- [NEG] Institutional focus. — Pricing tiers and onboarding are built around institutional clients, raising the barrier for casual retail traders.
- [NEG] Limited retail CGT automation. — No consumer-facing bed & breakfast rule engine comparable to retail-first competitors.
#3 Coinpass
Coinpass fits UK traders prioritising Lloyd's-backed custody assurance, though it outsources CGT calculation to third-party tax software rather than automating it natively.
Why Coinpass Ranks #3

- [NEG] No native CGT engine. — Relies on third-party tax software rather than an in-house pooling calculation engine.
#4 Kraken
Kraken suits UK users building their own trading bots via API, though it requires pairing with a separate tax tool since no native HMRC CGT engine exists in-platform.

- Verifiable Proof of Reserves. — Industry-benchmark cryptographic reserve auditing accessible to UK users.
- API-driven automation. — High-performance REST and WebSocket APIs enable automated AI trading bots.

#5 Gemini Europe
Gemini Europe fits UK users who prioritise certified custody and dual FCA registration, though HMRC CGT calculation still depends on third-party exports.
Why Gemini Europe Ranks #5
- Dual FCA registration. — Holds registration as both an Electronic Money Institution and a Cryptoasset Firm.
