Final answer:
A single nonresident is not required to file an Oregon tax return for interest from an Oregon bank savings account totaling $2780, as typical tax laws often have different requirements for interest income, especially at lower amounts.
Step-by-step explanation:
The question pertains to the requirement for filing a nonresident tax return in Oregon. Based on the information provided, which assumes we ignore any instruction details like Form 10402, and looking at the types of income, a single nonresident is not required to file an Oregon tax return if their income includes interest from an Oregon bank savings account of $2780.
Rental income, severance pay, and wages earned in Oregon typically have a filing requirement, as they are sourced to the state and exceed the standard for filing a return for nonresidents if over a certain threshold. Without specific information on tax thresholds for Oregon, the answer would be based on typical tax law where interest income is often taxed differently and may fall under different requirements, especially at lower amounts.
