  In this paper, we have investigated the late time cosmic acceleration issue
in the context of $f(R,T)$ gravity. The matter field is considered to be that
of viscous fluid. The model has been framed as a mathematical formalism and the
effect of viscous fluid on the cosmic expansion has been shown. The equation of
state parameter indicates the quintessence behaviour of the Universe at late
time. The theoretical results obtained here shows its alignment with the
cosmological observations result.
