Free concept demo · Canada only
All your brokerages. One Canadian tax picture.
TaxBack pools your adjusted cost base across every brokerage, catches superficial losses before they cost you, and lays your year out the way Schedule 3 asks for it.
The demo is a full seeded portfolio. No account, no brokerage, nothing to install.

What a single broker cannot tell you
Every number records the rule it applied and the Bank of Canada rate it used.
- The core problem
ACB pooled across brokerages
Each broker sees only its own accounts, so none of them knows your real adjusted cost base. TaxBack replays every non-registered account into one pool.
ALL NON-REGISTERED · EVERY BROKERAGE
- The rule people miss
Superficial losses, caught
Rebuy within 30 days and the loss is denied, even if the rebuy was in your TFSA. TaxBack moves the denied amount onto the replacement shares, or says when it is gone for good.
-30D … +30D · TFSA AND RRSP INCLUDED
- Before you sell
Harvesting with the dates
Positions worth less than their ACB, the gains each could offset, and the date before which buying back in any account would undo the whole thing.
