State tax filing

It depends.

If your intent is to return to MA, you will need to be able to show Rhode Island that you have no intention of staying.  The terms of your lease may be indicative of your intentions.  

Rhode Island includes having a clause which says "no change of domicile results from moving to a new location" indicating that your stay in Rhode Island could be considered temporary for tax purposes.  However, if you reside within the state for over 183 days, you would be considered a resident of Rhode Island and would need to file a tax return there.  This may become a factor in 2021 depending upon how long your lease is.

However, any income earned while you are within Rhode Island could be subject to state income taxes as a nonresident if the income is from Rhode Island sources.  Please see the attached excerpt for more information.

For 2020, you may be okay filing just your MA state tax return, but only if you did not earn any income within Rhode Island and meet the residency requirements as outlined above.
