1. When you are reporting business expenses do you do the total before or after tax?

As per the Canada Revenue Agency (CRA), when reporting for business expenses you include in the report any GST/HST incurred in these expenses. However, if you have remitted GST/HST or claimed the input tax, you do not include the GST/HST when reporting for the expense. 

For more information, please read this page from CRA - Expenses section of Form T2125 

Thank you for choosing TurboTax.
