How does my income affect the amount of GST/HST credit I receive?

You need to keep in mind that GST/HST credit is intended for low to middle-income households. The higher the income the lower the GST/HST credit will be. In the case of single individuals, the amount from line 23600 (net income) is the main determining factor in the calculation of the credit. For married couples their combined net incomes will be used. As GST/HST credit income thresholds vary from year to year, you are advised to contact the CRA or your nearest Softron office for the amounts applicable to you.
