Most Canadians leave money on the table. Here's what proper ACB tracking catches.
Return of Capital silently reduces your ACB. Miss it, and you'll overpay when you sell. We track every T3/T5 distribution automatically.
Reinvested distributions add to your ACB. Forget them and you're taxed twice—once on the distribution, again on the "gain."
Every commission increases your ACB and reduces your taxable gain. $9.99 here, $9.99 there—it adds up fast.
Denied losses should be added to your new ACB. Most people lose this deduction forever. We make sure you don't.
Paid foreign withholding tax? That's money back on your return. We track Box 34 so you can claim it.
Same stock in TFSA, RRSP, and taxable? CRA requires averaged ACB across accounts. Almost nobody does this right.
CRA has your T3 data. If your numbers don't match, you get audited. We make sure they match—and that you're not paying a cent more than you owe.
Your financial data deserves the highest protection. Here's how we keep it safe.
