Yes, you have to file a MS nonresident income tax return. Click on How do I file a nonresident state return?
If you are not a Mississippi resident but earned income in Mississippi then you have to file a nonresident return. While this return will require you to report your total income, it will only tax you on the income you earned in Mississippi. Do note that if your allowable deductions and exemptions are greater than your Mississippi income, you do not need to file a nonresident return.
