I am just about to trade futures contacts via a US based broker but I live in NZ (and are tax resident of NZ).
Is anyone aware of the tax obligations in the USA in such a situation ie do I have to file a US tax return? Are my net profits subject to any Witholding Tax by the IRS? etc.
I appreciate I will be subject to NZ tax on my net profits, this post is just about the US tax side (if any).
