I was hoping for SR&ED to be completely axed. It's a huge monstrosity of paperwork, to the point that small businesses pay 30% of their tax credits to consultants who fill out the forms for them and large businesses hire teams of people for the sole purpose of tracking and classifying SR&ED expenses so that the tax credits can be claimed. I suspect that Tarsnap is eligible for some SR&ED credits, but it's simply not worth the time and headaches it would cost me to claim them.
If Canada wants to encourage innovation, they should set up a system which rewards people for doing new and innovative things, not a system which rewards people for being good at filling out forms.
