Uhh, corporate taxes in the US vary state to state... In utah they are zero (which is alot less than here). And corporate taxes arent that burdensome in Canada either. As of 2010, the last year I checked, it was 16.9% of the first 400k in profit, and 35% for the remainder, in BC. Can't remember what component of that is prov/federal, or if it is all federal. Anyway, it is pretty easy for larger corps to keep taxes low, for example, (I actually have no idea if these guys specifically do this or not) if wholesale sports has a corp that is responsible for retail clothing, and a separate corp for reloading equipment (again, I dont know if this particular example is legal, but be sure that this happens in alot of large corporations) they pay 16.9% tax on 800k. repeat as necessary. Corporate tax is pretty much a non issue, for the big money anyway. Now, unless you happen to have a 500k/yr tax accountant on retainer, dont try this at home, kids...
I would like to disagree with your take on corporate taxes. On a federal level corporate tax here is about that 17% rate, and in the US about 35%. Corporate tax is a big issue for the big money, this is why many US corporations have moved there head office to Canada, Ireland, and other places. The tax savings are huge, but our prices here are still higher. This is starting to change, only because of public awareness.
I have heard all of the arguments for and against the fair or non fair prices in Canada. ( It costs so much more to ship here,,, Bull Crap,,, It cost so much more to do business here,,, very slightly, and mainly because of fairer wages,,, Our tax system is not business friendly,,, Bull Crap, our lower corporate taxes offset the extra in wages, etc hands down,,,, We are a smaller market,, smaller than what? Smaller than all of the US yes, bigger market than, Texas, or California, or New York. All products must be distributed to all the dealers in any of these places, so it is a matter realy of how much more does it cost to deliver a product to Calgary, or Toronto from say Oregon, than it does to send it to Florida,,, Not much if anything, and maybe less. One way or another the price of say a scope delivery difference of $10 to $20, does not justify, a price difference of $hundreds.
