Crypto Tax Tracker — AU & US

A browser-based tool for Australian and US crypto traders who want to

calculate their capital gains without uploading their transaction history

to a third-party service.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHAT IT DOES

• Calculates capital gains and losses from your crypto transactions

• Supports Australian rules: July–June financial year, 50% CGT discount

for assets held 12+ months, capital loss offsetting

• Supports US rules: short-term vs long-term classification, Form 8949

categories, Schedule D totals, $3,000 capital loss deduction against

ordinary income with carryforward

• Four cost basis methods: FIFO, LIFO, HIFO, and Specific ID

• Alerts you to possible wash sales (30-day repurchase after a loss)

• Imports CSV files from Coinbase and CoinSpot, plus a general CSV format

for most other exchanges

• Exports a CSV report compatible with Form 8949 / CGT summaries, and a

printable PDF report

• Shows live public crypto prices (via CoinGecko) alongside your data

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHAT MAKES IT DIFFERENT

• Privacy-first: It runs entirely in your browser. No account. No server.

No API keys. Your transactions are never uploaded anywhere.

• One-time payment. No subscription. No recurring fees.

• Built-in guided setup: A 5-step wizard for first-time users, plus

"Explain My Numbers" — every figure in the report can be traced back

to the exact calculation and the relevant ATO or IRS rule.

• Works on desktop and mobile browsers.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

HONEST LIMITATIONS

• Only Coinbase and CoinSpot have dedicated CSV importers. Other exchanges

can be imported using the general CSV format (documented inside the tool).

• LIFO, HIFO and Specific ID require that you can prove which units you

sold, in line with ATO and IRS requirements.

• Does not cover DeFi positions, staking derivatives, NFTs, gifts,

lost/stolen coins, or business trading activity.

• Does not currently support countries outside Australia and the US.

• Your data is stored only in your browser's local storage. Clearing your

browser data will erase it — use the Backup (JSON) button regularly.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

WHAT YOU GET

• A single HTML file — open it in any modern browser, no installation

• A built-in guide ("Cham") that explains the tool and AU/US tax rules

• Quick Start guide and FAQ

• Free updates to the current version

⚠️ IMPORTANT

This is a calculation tool, not tax advice. It performs arithmetic on the

figures you enter and applies published ATO and IRS rules. Tax situations

vary, and rules change. Before filing, verify your results with a qualified

CPA or registered tax agent.
