Is the HST rebate eligibility - of up to $166,000 combined income per couple - based on gross income or net income?
The OSTTB is calculated based on the adjusted family net income of the recipient. Adjusted family net income is the sum of your net income (line 236 on your income tax return) and your spouse's or common-law partner's net income with certain adjustments. Adjusted family net income is the definition of income most commonly used to assess eligibility for benefits delivered through the tax system. [emphasis mine]
