Lock in launch pricing today. One purchase and you'll receive updates for as long as the product is maintained.
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.
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.
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.
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.
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.
They all require you to upload your complete financial history to their cloud. Sovereign Tax solves the same problem without any of the risk.
Every major crypto tax platform requires full transaction history uploads. Your entire financial life, stored on infrastructure you don't control.
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.
Your data stays on your device, encrypted with AES-256. No accounts. No cloud. No tracking. We have no access to your data.
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.
Not because we have better security than them. Because there's nothing to hack. We don't have your data. Period.
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.
