BUMP....
i'm curious about this subject...........
i assume if you are canadian and you have big $$$ in vegas that it is in fact taxable and you need offsets - losses, fees, expenses etc. - to bring the taxable amount down - hopefully to zero.
and my sense is that if you win $5K and they withhold tax they'll probably just give it back when you file to get it back because it would so easy to come up with those offsets - whether genuine or not.. coming up with $300K of offsets is not so easy.
i saw reference to this.. but does the USA government only care about offsets from the USA? i.e. again fees, losses, expenses incurred in the usa or travelling there. but NOT canadian casino entry fees for example.
thanks in advance
