US Tax Form 8840 For Canadian Snowbirds

I fill it out every year. It is a requirement to avoid the possibility of having the IRS claim you owe taxes on your world income which under the laws of the United States, it is their right to do if you meet the non-resident alien classification. They rarely do this unless you have generated income in the US (earn interest, rent your park model out, have capital gains, etc.) but why take the chance. Filling out the form is easy to do.
