Capital Gain Calculator
Work out the capital gain or loss on a completed or proposed disposition, for an individual, corporation or trust, then turn the result into a client-ready letter, not just a number on screen.
The calculation is only half the work. CodaraFlow finishes the explanation, the tables, and the client-ready letter.
The Gain, the Relief, and the Tax
This is one of the built-in calculations in CodaraFlow. Enter the property, the proceeds and the cost, and it computes the gain or loss, applies the available relief and deferrals, and estimates the resulting tax.
- Gain or Loss on the DispositionProceeds less cost and selling costs, on a completed sale or one the client is considering.
- Any Owner, Any PropertyIndividuals, corporations and trusts; real property, shares and other capital property, including depreciable property where applicable.
- Every Relief That AppliesThe principal residence exemption, the lifetime capital gains exemption, capital gains reserves and replacement-property deferral, applied where the file qualifies. The provision behind each is under The Basis below.
- Depreciable-Property EffectsRecapture of CCA and terminal losses calculated where applicable.
- The Estimated TaxAn estimated tax figure, and for a corporation the capital dividend account addition.
From the Calculation to a Client-Ready Letter
The number is not the deliverable. In CodaraFlow the result drops straight into a letter section: the firm’s approved wording, the computation tables, and the statutory notes that actually apply to this client, written in for you. Exported as an editable Word document on your letterhead.
The same reviewed explanation, not whatever the preparer types today.
The relief, recapture, and tax-estimate notes appear only when the file triggers them.
The disposition computation is laid out and footed automatically.
Finish it in Word, on your firm’s letterhead. No proprietary format.
Grounded in the Provisions You Cite
Each part of the calculation ties to the section a reviewer would expect. The wording is firm-editable; the sections are fixed by the Act.
The taxable portion of a capital gain is the gain multiplied by the inclusion rate.
Shelters qualifying gains against the individual’s available deduction balance.
May shelter all or part of the gain for years designated as the taxpayer’s principal residence.
On depreciable property, capital cost allowance previously claimed may be recaptured as income (s. 13(1)), or a shortfall below the undepreciated capital cost may be a terminal loss (s. 20(16)).
A loss on personal-use property is denied.
For a corporation, the non-taxable portion of the gain adds to the capital dividend account and may generally be distributed tax-free by capital dividend election.
Where qualifying replacement property is acquired within the time limits, the gain may be deferred.
The estimated tax is estimated only. It excludes Alternative Minimum Tax (where applicable), the OAS clawback and surtaxes, and any other income or deductions of the taxpayer.

Questions About This Calculation
Is this a standalone calculator?
No. It’s one of the built-in calculations inside CodaraFlow. The result becomes a client-ready letter section, complete with the computation table and the notes that apply, not just a figure you copy into a client letter.
Completed sale or a proposed one?
Both. Run it on a disposition that has happened, or model one the client is considering.
Can we change the wording and which notes appear?
Yes. Every sentence and every note is firm-editable, and can be overridden on an individual letter.
Does any client data go to an AI?
No. The app never connects to AI. Deliverables are assembled from structured facts and your firm’s approved wording.
