In this work we obtained solutions of field equations for perfect fluid spherically symmetric static spacetimes and found their concircular vector fields (CCVFs) in $f(R,T)$ gravity theory. It came out that special classes of these spacetimes possess either $4$-dimensional or $15$-dimensional CCVFs.
