How do I know how much income belongs to Arkansas if I'm a nonresident of Arkansas?
Nonresident income is usually considered to be any income derived from Arkansas sources and/or received as Arkansas residents (no matter where the income was earned).
For example, if you lived in Georgia but worked in Arkansas for a few weeks, you would need to report the Arkansas income on a nonresident Arkansas return.
Also, if you received business income in Arkansas while living in another state, then you would enter any business income received in Arkansas on this screen.
