Frequently asked questions
HMRC requires disposals to be matched to acquisitions in a set order: same-day first, then anything you bought in the following 30 days (the "bed and breakfasting" rule), then your Section 104 pool. The order changes your gain. CGT Foresight applies all three rules automatically and shows you exactly how each disposal was matched.
You'll find the platforms we import from in the Supported trading platforms section above. We add new brokers on request — sign up, send us a sample export, and we'll build the importer for you.
We convert using European Central Bank daily reference rates and store the rate used against each trade for your audit trail. You can override any rate manually when you'd rather use HMRC's published figures.
Yes. You can invite your accountant to view or edit your account. Accountants can also manage multiple clients from a single login.
No. CGT Foresight is a calculation tool to help you prepare figures for Self Assessment. It does not provide tax, legal or financial advice — always check your figures and consult a qualified accountant if in doubt.
Stop wrestling with spreadsheets.
