"...but rather a myth perpetuated by TurboTax because the software doesn't support dual state residence."
First, you're commenting on an almost 5-year-old thread. Second, no one at TurboTax has ever denied that dual residence is possible. A taxpayer can certainly be both a domiciliary resident of one state and at the same time a statutory resident of another. The TT software isn't set up well to handle dual residency, but TT isn't "perpetuating" any "myth" about it.
