My, my... a topic near and dear to me.
OK. First of all, remember this. A long time ago, CRA got shut down in court when they attempted to tell some people who operated a business with continued losses that they would no longer accept the losses.. or would ask when they expect to make a profit.
In court, the long and short of it was that AS LONG AS you operate like a business... you can continue with losses for as long as it takes. There is nothing illegal about loosing your money (technically that is)
Now, know that, I would stay away from stupid tax things like lunches, etc. That will only lead to rejects and audits. But what about car, home office, computers and all related things, office supplies, postage, post office box rentals, printing, advertising, flyers and distribution. Anything else?? There's a lot. Pretty much anything but groceries (haven't figured that one out yet).
Like I said, stay away from the one people get snagged on like the lunch and entertainment.
But then there's a ton of other tricks if you want to invest a little. Sorry, I will not discuss them here. Not illegal or anything like that, just that it took me years to get these figured out... and I am not going to spill it here. Contact me if you need more help!
