What CryptoCGT does

CryptoCGT is a UK-focused web application that calculates Capital Gains Tax (CGT) on cryptocurrency disposals for UK individuals filing HMRC Self Assessment. Operated as a sole trader business by Mai Thanh Tung from Đà Nẵng, Vietnam, the tool accepts CSV transaction exports from crypto exchanges (Binance, Coinbase, Kraken, and others via column mapping) and applies HMRC's three-tier matching rules — same-day, 30-day bed-and-breakfast, and Section 104 pooling — in the order specified by HMRC's Cryptoassets Manual. The calculation engine is cross-validated against HMRC's published worked examples (CRYPTO22251–CRYPTO22256) and the independent BittyTax open-source calculator, with every figure displayable line-by-line alongside the matching rule and trade references that produced it.

The product is structured as a single self-serve web tool on a freemium model. Users can view their full CGT figure — proceeds, net gain, estimated CGT, and Section 104 working — on screen without creating an account and without payment. A £49 fee per tax year (VAT included; £29 for founding members) unlocks the SA108-ready PDF report and full CSV audit trail, with all prior tax years included at no additional cost. The platform never requires API keys or exchange logins; it processes only uploaded CSV files over encrypted connections and does not retain data after report computation. Downloaded reports are stored as locked, dated copies that subsequent imports cannot silently overwrite, providing a verifiable audit trail of what was filed.

Distribution is entirely product-led and content-driven, running exclusively through cryptocgt.com with no channel partners, resellers, or sales team. Acquisition depends on an extensive library of SEO-optimized educational guides covering UK crypto tax topics — CGT rules, staking, airdrops, Self Assessment, SA108 boxes 13.1–13.8, CARF compliance, deadlines, and nudge letters — that capture organic search traffic from UK individuals researching their crypto tax obligations. Payments are processed by Paddle as Merchant of Record. Customer support is provided via email with a stated one-working-day response time. The business is bootstrapped, with no external funding, no venture investment, and no headcount beyond the founder-operator.

Core offering

CryptoCGT is a web-based UK crypto Capital Gains Tax calculator that ingests exchange CSV files (Binance, Coinbase, Kraken, or any other via flexible column mapping) and computes the user's CGT figure using HMRC's three matching rules — same-day, 30-day bed-and-breakfast, and Section 104 pooling — applied in HMRC's prescribed order. Users can view their full CGT figure free with no sign-up, and pay £49 per tax year to download an SA108-ready PDF report with full CSV audit trail, designed for HMRC Self Assessment filing.

Product overview

CryptoCGT is a single, unified SaaS tool for UK crypto Capital Gains Tax calculation. The product consists of one core offering: a web-based calculator that accepts CSV transaction files from crypto exchanges (Binance, Coinbase, Kraken, and any other via column mapping), processes them using HMRC's matching rules (same-day, 30-day bed-and-breakfast, Section 104 pooling), and presents the resulting CGT figure with full working shown. The free tier allows users to upload CSVs and see their complete tax figure on screen with Section 104 workings displayed. The paid Filer tier (£49 per tax year) unlocks the downloadable SA108-ready PDF report with full CSV audit trail. There are no separate modules, add-ons, or platform architecture — it is one product with a free preview and a single paid download.

Partnerships

One partnership is on record.

• BittyTaxminorOthersBittyTax is an independent open-source UK CGT calculator used by CryptoCGT as a cross-validation reference. CryptoCGT's calculation engine is verified against both HMRC's own published worked examples and BittyTax's independent implementation. When two separate implementations of the same law agree to the penny, the result provides stronger assurance of accuracy than either alone. This is a reference/validation relationship rather than a formal commercial partnership.
