There have been a few announcements of actual wage increases that corporate PR departments have tried to attribute to the tax cuts, but in every one I've looked at, it was clear the wage increase was just the result of normal market forces and dressed up to pretend it was the result of tax cuts. For example, a few banks (including Wells Fargo) announced a minimum wage increase to $15/hour, but Bank of America announced that same change at the end of 2016, before any tax cuts.
