Here is the US version of this. The US federal government does not tax any income under $91,600. If you are being paid by a US company you still have to pay social security and Medicare taxes but not US tax on $91,600. This is all dependent on the fact that you are out of the country for more than 335 days a year. Of course with the big O in office this is subject to change at anytime! As far as state tax, I would still be liable for Alabama taxes but I plan on moving to Florida before I leave for Thailand to avoid the state tax. Florida does not have state income tax. Hope this helps although the Canadian rules are probably much different.
