Dual-Status Taxpayer
In the year of transition between being a nonresident and a resident for tax purposes, you are generally considered a Dual-Status Taxpayer. A Dual-Status Taxpayer files two tax returns for the year—one return for the portion of the year when considered a nonresident, and another return for the portion of the year considered a resident. In some situations, a taxpayer can elect to be treated as a full-year resident in the transition year to avoid having to file two separate returns.
