Accuracy over flashy features
Every result traces back to the transaction data you provided and the allocation method you chose. No hidden heuristics.
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.
I built CGT Strategist because I needed it for my own tax. I was trading across multiple brokers, holding ASX and US stocks, and every financial year I'd end up in a spreadsheet trying to figure out which parcels were allocated to which sale, what the ATO FX rate was that month, and whether FIFO was actually the right approach. It took hours and I still wasn't confident in the numbers.
Most broker platforms show FIFO by default and provide limited reporting. But under Australian CGT guidance, investors are allowed to identify specific parcels in many cases, which means the method you use can materially change your calculation results. A good tool for comparing those methods didn't seem to exist, at least not one that was affordable, showed its working, and let you explore different approaches properly.
So I built one. CGT Strategist lets you:
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:
So you and your accountant can see exactly how each result was produced.
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.
You're uploading sensitive financial data, full trading histories across years. I take that seriously.
Your financial data should never become a hidden revenue stream.
When it comes to tax records, boring and predictable is exactly what you want.
Every result traces back to the transaction data you provided and the allocation method you chose. No hidden heuristics.
Evidence Packs show the full working, parcel by parcel, rate by rate, so every number can be verified.
Where the platform takes a position (FX direction, discount eligibility, rollover logic) it tells you which rule it applied and why.
