Took a new full time job in 2018 in PA. For 2018, we didn't establish residency in PA, but rather commuted. Does this constitute a non-resident status for tax purposes?

Yes, if you were working in PA and living in another state, you were a non-resident for PA income tax purposes.

Pennsylvania has signed reciprocal agreements with Indiana, Maryland, New Jersey, Ohio, Virginia, and West Virginia under which one state will not tax employee compensation, subject to employer withholding of the other state. ... Because of the reciprocal agreement, you pay taxes to your state of residency.

Thank you for the response.  My company provided me corporate housing and the plan is to relocate in 2019.  GA doesn't have reciprocal agreement with PA.  Our physical address is still GA, including our drivers licences etc.

Without a reciprocal agreement, PA will tax you on your in-state earnings. As your state of residence, GA will also tax you on those earnings, but should allow a credit for the taxes paid to PA. Every state has unique rules about how to calculate the credit and it tends to not be a perfect 1-to-1 offset, but it helps ease the burden.
