Your year-end to-do list, crossed off

If your corporation holds investments, someone spends a few evenings each year rebuilding the records. Usually you, then your accountant, all over again.

Year-end to-do

FY 2026

  • Exporting activity from every account and stitching the files together

    Import each account’s export. Duplicates are caught and the original file is kept.

  • Looking up the Bank of Canada rate for every US-dollar trade

    Each trade, dividend and fee is converted at that day’s rate, with the rate on record.

  • Digging up last year’s ACB spreadsheet and hoping it’s the final version

    Close the year and its balances carry straight into the next one.

  • Working out what reinvested distributions and return of capital did to cost base

    Reinvestments and adjustments land on the right holding, in the right year.

  • Your accountant redoing half of it anyway

    A workpaper where each figure opens up to the trade behind it.

Handles the parts that make this tedious

US trades, in Canadian dollars

Rates come from the Bank of Canada and sit next to each conversion, so anyone can check the math later.

Says what’s missing

No purchase history for a holding means no gain until there’s a cost to work from.

Needs input

Gain on hold until a cost is entered.

Years close. Balances carry over.

Lock a finished year and start the next with the same holdings and cost base. A late tax slip goes through a recorded amendment, not a quiet edit.

What it won’t do

File your T2. Your accountant does that, with the software they already use.

Guess. If a cost or a classification is missing, it asks you instead of filling something in.

Overreach. Capital dividend account and RDTOH balances need records beyond your brokerage, so they aren’t in the first version.
