What percentages do I enter in my Investment Tax Credit form in the T2038 line number and Class dropdowns??

Hi, you need to make sure that you qualify to claim the Investment tax credit (ITC).    Here is a link to line 41200 from the CRA that is giving you all the details around T2038 and what qualifies under the ITC.  Borrowing money for investment does not necessarily giving you access to ITC.
