When you credit a rebate at closing, you’re not just advancing the money. You’re taking a position on whether that purchaser qualifies.
If they didn’t, the liability can come back to you. The Excise Tax Act makes builder and purchaser jointly and severally liable where a rebate is paid or credited to someone who wasn’t entitled to it.
That matters more than it used to, because the first-time buyer programs turn on a four-calendar-year ownership lookback that includes the purchaser’s spouse. You’re being asked to verify something you have no way to verify — from a declaration signed by the person who benefits from the answer.
There is a cleaner position: don’t credit. Let the purchaser claim directly, with a specialist preparing the application.
They get the rebate. You carry no cash-flow exposure and no liability. And the conversation changes from “we’re not giving you your rebate” to “here’s who handles this, and they do it for a living.”
