I would not. I increase my fees each year without informing, though as missingdonut said, some will get a slight break due to TCJA while others will be paying even more. I have never believed in keeping fees flat, or notifying clients of small increases in fees, because it then sets a standard they come to expect. As it stands now, their standard is to expect a slight increase each year, but they pay it because of the level of service. I have witnessed others fall into the trap of clients throwing a tantrum over a $10 increase, as someone else pointed out.
