Tennessee Non-Resident Notice is a document issued by the Tennessee Department of Revenue that is required for non-residents of the state who receive income from sources in Tennessee. There are two types of Tennessee Non-Resident Notice: TN-NRT (Tennessee Non-Resident Tax) and TN-NOS (Tennessee Non-Resident Occupational Surcharge). TN-NRT is used to report income from wages, salaries, commissions, dividends, interest, and other income earned from activities in Tennessee. TN-NOS is used to report income from Tennessee occupations such as engineering, law, accounting, real estate, and other professions. Both documents must be completed and returned to the Tennessee Department of Revenue within 30 days of receiving income from Tennessee sources.
