Accuracy over flashy features
Every result traces back to the transaction data you provided and the allocation method you chose. No hidden heuristics.
About
Built by an Australian investor
who needed it.
CGT Strategist is a calculation and reporting tool, not a trading platform or a tax advisor. It exists so Australian investors can get honest, auditable capital gains numbers without spending hours in a spreadsheet.
Why I built this
The spreadsheet wasn't working.
I built CGT Strategist because I needed it for my own tax. Trading across multiple brokers, holding ASX and US stocks, every financial year ended in a spreadsheet: which parcels went to which sale, what the ATO FX rate was that month, whether FIFO was even the right call. Hours of work, and I still wasn't confident in the numbers.
Brokers show FIFO by default, but Australian CGT guidance lets investors identify specific parcels in many cases, and the method can materially change the result. A tool that was affordable, showed its working, and compared those methods properly didn't seem to exist. So I built one: import real broker data, compare allocation methods side by side, and generate structured EOFY records without the spreadsheet.
Focus
Designed for real-world tax record keeping.
CGT Strategist is not about chasing trading performance or predicting markets. It's focused on one thing: clear, auditable capital gains calculations and documentation.
The platform is designed around:
- Parcel-level trade tracking
- Transparent cost base calculations
- ATO-referenced CGT logic
- FX handling using your choice of ATO monthly or RBA daily rates
- Evidence Packs that show full calculation trails
So you and your accountant can see exactly how each result was produced.
Not advice
Calculation tools, not financial or tax advice.
CGT Strategist is a calculation and reporting engine. It does not provide financial, tax, or legal advice.
It applies publicly available ATO guidance to the transaction data you provide and generates calculation outputs based on your selected allocation methods. Your personal circumstances, broader tax position, and eligibility for specific concessions are not assessed by the platform.
If you're unsure how CGT guidance applies to you, you should always consult a registered tax professional or refer to ATO guidance.
Privacy
Your data is not a revenue stream.
You're uploading sensitive financial data, full trading histories across years. I take that seriously.
- I do not sell or trade identifiable portfolio data
- Uploaded data is used only to calculate your results and generate reports
- Usage analytics are aggregated and anonymised
- Secure encrypted connections are used at all times
- You can delete your data and workspaces from within the app
Your financial data should never become a hidden revenue stream.
Priorities
Built to be boringly reliable.
When it comes to tax records, boring and predictable is exactly what you want.
Traceability over shortcuts
Evidence Packs show the full working, parcel by parcel, rate by rate, so every number can be verified.
Clear assumptions over hidden automation
Where the platform takes a position (FX direction, discount eligibility, rollover logic) it tells you which rule it applied and why.
