I moved to nv in September of 2010. I still work for an Idaho company out of my home. I get a 1099-misc from the Idaho company and I file federal as self employed. Can I state my residency full year residency as Idaho still?

Negative. You file as the resident of the state where YOU live, not where the "employer" is located.

No Idaho tax return is required,

taxnewb: although you don't state it explicitly, it sounds as if you may have lived and worked in Idaho up until September. If so, then you must file with Idaho as a part-year resident to cover your January - September income, and also file with Nevada as a part-year resident (for September - December).

Ebaines:

Good point about filing the Idaho return as a part-year resident; that's what I get for reading posts past midnight.

However, a Nevada return is NOT required for obvious reasons.

Doh! Of course you're right. I guess I was thrown off by the OP's question about wanting to declare ID residency for the full year. You would think anyone moving to a state with no income tax would be trying to figure a way to declare residency in the new state for the full year, not the other way around.
