From the first question to reviewer follow-up
Treat acquisition and disposal as separate evidence points
Do not rely on one current rate or one copied source link for both sides of the calculation. Keep the acquisition record, disposal record, and selected official reference input for each date.
Keep the calculation outside the proof
The tax workpaper should explain cost basis, proceeds, dates, allowable source, and treatment. FXProof records the supported official source and selected date used for each exchange-rate input.
Attach two proof documents when two dates are used
Open and keep a Signed FXProof Proof PDF for the acquisition-date input and another for the disposal-date input when both are part of the file. Each proof carries its own document id, payload hash, rate context, and verification details.
Handle missing publication dates openly
If a selected acquisition or disposal date has no published observation, keep the adviser or rule note that explains which available date was used. FXProof documents the date you selected; it does not choose the rule.
Give the reviewer a checkable trail
A reviewer can check each proof document independently without access to your account. Acceptance, tax treatment, and the calculation conclusion remain with the recipient, procedure, and jurisdiction.

Do I need separate proof for purchase and sale dates?
Use separate proof records when the workpaper uses separate acquisition-date and disposal-date exchange-rate inputs. Keep the calculation and tax reasoning outside the proof.
Does FXProof calculate my capital gain?
No. FXProof documents selected official reference inputs. It does not determine tax basis, allowable dates, gain, loss, or tax treatment.
Can a reviewer check both proof records?
Yes. Each proof has its own document id and payload hash for public verification.
