The CRA views major renovations as "New Construction" if you meet specific structural thresholds. We specialize in navigating the 70-90% interior rule and the $90/sqft benchmark. If you have spent over $125,000 on a renovation in Ontario, you are likely sitting on a massive tax refund that your builder or accountant has not fully quantified.


RebateMax is built specifically for Ontario custom homes, luxury builds, and substantial renovations. We are not a generalist accounting firm dabbling in rebates—we live and breathe HST housing legislation so you do not have to.
Result: You keep more of your rebate, file faster, and sleep better knowing your claim is built by specialists.
