I handle accounting as well as tax prep for a Client. I gave them notice in early Jan that I would not be able to continue providing the accounting services in 2025 (did not provide a reason but  this is a whole other story that involves business practices that I am not comfortable with). I filed an extension for 1040 with Sch C since they provided me with their other info last week. I got the return done yesterday...they are saying they do not understand and agree with the outcome of the return.

I have sent them details to support to the Sch C profit (it is not enough in their opinion). Even if they come back and say ok they agree with the numbers, I am thinking I need to cut them loose.

What would you do? Tell them to go find another tax preparer?
