To continue with the dialog:
I am not asking for tax advice. I am just reporting a tax event that happened to me. I am not trying to equate stock dividend taxes directly with visitation time limits and tax consequences related to those limits. What I am trying to do is look at the broader picture of The IRS and Revenue Canada taxing citizens of other countries.
What I am asking for is what I stated in the first paragraph of my original post which is...... "From time to time Canadians have discussed the possibility of the IRS making a money grab for their income if they overstay their allotted time in the USA without filing the required tax form to prevent this. Has anyone on this Forum actually had this happen to them?"
