Accurate ACB
Is Table Stakes.

The cost base infrastructure for tech-forward securities firms and fintech platforms. Give your clients the ACB accuracy they deserve—and the tax savings they're missing.

What Your Platform Is Getting Wrong

Most portfolio management software ignores the details that cost your clients real money. ACB Platform catches them all.

Return of Capital

ROC silently reduces ACB on every distribution. Miss it and your clients overpay capital gains tax on exit. We ingest CDS T3/T5 data automatically.

DRIP Reinvestments

Reinvested distributions increase the cost base. Without tracking them, clients get taxed twice—once on the distribution, again on phantom gains at sale.

Superficial Loss Rules

CRA's 30-day rule denies capital losses and rolls them into the replacement property's ACB. If your system doesn't handle this, clients lose the deduction permanently.

Commission Cost Basis

Trading commissions increase ACB and reduce taxable gains. For active portfolios this adds up to thousands in tax savings your clients are leaving on the table.

Foreign Withholding Tax

Foreign withholding tax paid is recoverable via tax credits. We track Box 34 amounts so advisors can ensure clients claim every dollar back.

Multi-Account Averaging

Same security held across registered and non-registered accounts requires averaged ACB per CRA rules. Virtually no platform handles this correctly.
