Where do I move a negative CCA to in my income and; Do I put a $0 in the space where the negative # appears now? Program won't let me past it.

Is the negative CCA from the sale of a vehicle, rental property, or equipment?

Sale of a vehicle that I used for work purposes sometimes, yes.

Because there are a number of possible scenarios (employment vehicle versus business vehicle, new CCA entry, etc.), it's best that you contact one of our phone support team members. The agent will be able to view your screen (with your permission of course) and assist you in entering the proper amounts in the right places.
