We investigate the behaviour of two-dimensional quantum field theories with$\mathcal{N}=(0,2)$ supersymmetry under a deformation induced by the`$T\bar{T}$' composite operator. We show that the deforming operator can bedefined by a point-splitting regularisation in such a way as to preserve$\mathcal{N}=(0,2)$ supersymmetry. As an example of this construction, we workout the deformation of a free $\mathcal{N}=(0,2)$ theory and compare to thatinduced by the Noether stress-energy tensor. Finally, we show that the$\mathcal{N}=(0,2)$ supersymmetric deformed action actually possesses$\mathcal{N}=(2,2)$ symmetry, half of which is non-linearly realised.
