FULL YEAR RESIDENT You are a full year resident if you lived in Arkansas all of calendar year 2021, or if you have maintained a domicile or Home of Record in Arkansas during the tax year.
NONRESIDENT You are a nonresident if you did not make your domicile in Arkansas.
PART YEAR RESIDENT You are a part year resident if you established a domicile in Arkansas or moved out of the state during calendar year 2021.
MILITARY PERSONNEL If Arkansas is your Home of Record and you are stationed outside of Arkansas, you are still required to file an AR1000F reporting all of your income, including U.S. active duty military compensation. However, active duty military compensation is exempt from Arkansas tax beginning in tax year 2014. (If you are stationed in Arkansas and your Home of Record is another state, Arkansas does not tax your U.S. active duty military compensation.) U.S. active duty military compensation includes wages received by members of the Army, Navy, Air Force, Marine Corps, Coast Guard, National Guard, and Reserve Units.
