Basically, no. It is 50% of the loaded labor rate of all employees doing R&D activities on projects that your liaison agrees qualify as R&D. When you work out of your home, rent/mortgage on your home are specifically excluded as business expenses (by CRA), so they can't be included. Working out of an office, you get about 65% of salary back; out of a basement (my situation), it is basically 50% of salary.
Oh -- hardware purchases and the like don't count, and you have to be able to prove the salary was paid, so as far as I know there is no game to be played with stock options.
Odd, we got to put the entire amount of the Tesla grid that we put together towards the SRED credits. Having said that I just filled out the paper work and handed it to the lawyers and accountants, perhaps they took it off afterwords?
