You may be overpaying on
Bitcoin taxes.

Most tax software uses FIFO — selling your oldest Bitcoin first. That's often your cheapest Bitcoin, which means the biggest taxable gain. Sovereign Tax gives you Specific Identification — you choose exactly which lots to sell.

✨ One-Click Optimize
Don't want to pick lots manually? Hit Optimize and the algorithm does it for you — scoring every lot by its estimated tax impact, accounting for non-discount (47%) vs. discount-eligible (23.5%) rates. It picks losses first, then the smallest gains, automatically minimizing your tax bill.

  • Losses first — harvest tax savings before touching gains
  • Rate-aware — prefers discount-eligible lots (23.5%) over non-discount (47%)
  • One click — review the selection, adjust if needed, confirm
  • As of early 2026, CoinTracker and Koinly offer FIFO only

A single sale of 1 BTC with the right lot selection may save hundreds to thousands of dollars in taxes compared to FIFO. The difference compounds with every sale you make.

Optimize an entire year
in one click.

Already imported your trades? Click Optimize All and the engine re-assigns every sell transaction for the year to the tax-optimal lots — automatically. No manual lot picking required.

Before applying, you see a side-by-side comparison: FIFO gain/loss vs. Optimized gain/loss, with your estimated savings in green. Review it, then apply with one click.

  • Batch optimization — every sell for the year, processed chronologically
  • Before & after comparison — see exact FIFO vs. Specific ID savings before applying
  • Fully reversible — one click to revert all back to FIFO
  • Fine-tune after — adjust individual sales with the per-transaction Lots editor

Donate Bitcoin.
Skip the tax bill.

When you donate appreciated Bitcoin directly to a deductible gift recipient (DGR), you may owe zero capital gains tax on the appreciation — and you may be able to claim a deduction for the full market value. It's one of the most powerful tax strategies in crypto, and most major crypto tax platforms don't track this.

Sovereign Tax AUS tracks every donation as a proper disposal — consuming the correct lots, recording FMV at the time of donation, and generating data for your gift deduction records.

  • Potential zero capital gains — donating appreciated BTC may avoid the tax you'd pay by selling first
  • Potential market value deduction — you may be able to claim a deduction for the full market value, not just your cost base
  • Specific ID for donations — pick exactly which lots to donate for maximum tax benefit

Donating 1 BTC bought at A$15,500 when it's worth A$155,000? You may avoid up to A$139,500 in capital gains and deduct the full A$155,000. Selling first and donating cash could cost up to A$65,600 in taxes. Example only — actual results depend on your tax situation.

The problem with every other
crypto tax tool

They all require you to upload your complete financial history to their cloud. Sovereign Tax solves the same problem without any of the risk.

👁

Your data on their servers

Every major crypto tax platform requires full transaction history uploads. Your entire financial life, stored on infrastructure you don't control.

💸

A$300/year subscriptions

They charge you annually for the same data. Miss a renewal and lose access to your own records. Your tax history, locked behind a paywall.

🔒

Sovereign Tax is different

Your data stays on your device, encrypted with AES-256. No accounts. No cloud. No tracking. We have no access to your data.

Cloud-based crypto tax tools
keep getting breached.

Every major crypto tax platform stores your financial data on their servers. When they get hacked — and they have — your transaction history, balances, and identity are exposed.

  • Jan 2026 Waltio — 50,000 users' tax data stolen including gains, losses, and account balances. Data sold on the dark web.
  • Nov 2025 CoinTracker — Mixpanel breach exposed emails, IP-derived locations, device metadata, and transaction summaries.
  • Dec 2022 CoinTracker — 1.5 million users' emails leaked. Victims later targeted in phishing attacks — one lost $1.7M.
  • 2020 CoinLedger — Customer data stolen and sold on a dark web forum.

No cloud servers to breach.

Not because we have better security than them. Because there's nothing to hack. We don't have your data. Period.

  • No servers — your data never leaves your computer. There's no database to breach.
  • No accounts — no email, no password, no identity stored anywhere.
  • No third-party analytics — no Mixpanel, no SendGrid, no tracking pixels. Minimal attack surface.
  • AES-256 encrypted on your device — even if someone steals your laptop, your data is locked.
  • Source-available — verify every claim yourself. Read the code. We have nothing to hide.

Know your tax bill before you sell.

Most people discover their capital gains tax after filing. Sovereign Tax lets you simulate any sale and see the exact tax impact instantly — which lots get used, the holding period, and whether it's non-discount or discount-eligible.

  • Enter any BTC amount and price — see gains in real time
  • Compare FIFO and Specific ID — pick the lots that minimize your tax
  • One-click Optimize auto-selects the best lots using per-lot tax scoring
  • Save lot selections and carry them to Add Transaction when you're ready to record
  • Nothing is recorded — purely hypothetical until you commit
