Typical digital filters for this are linear phase hence no in band phase distortion.
In the analog world high order filters introduce phase shift though, higher order/sharper roll off = more phase shift/phase distortion.
In the digital world filters can be chosen to mimic analog filters with phase shift or to be linear phase or anything between.
