Anyone in canada know how taxes would work with a US based broker? I trade equities/options right now with a canadian broker and they send me tax reciepts every year. Now I opened a futures trading account based in the US, how do I file taxes? what if I simply don't take anything out? can I just keep letting my investments compounds without paying taxes since they are US based income, but im exempt from US taxes, and canada has nothing to do with those profits.
