Client said his lawyer has made an mistake or something which caused him additional tax to pay in his 2016 tax return. Therefore, he is asking me to write a letter to certify his 2016 tax bracket, with my company letterhead and my signature. My impression is that he will be using it to ask for compensation from the lawyer.
Just writing a letter to certify tax bracket seems to be simple and straight-forward enough to me. It may just cost me five minutes to do it. But the fact that it is going to be used in his attempt to ask for compensation from a lawyer might have legal implication.
So, would you do it facing the situation? Refusing to provide such a simple and straight-forward letter might cause you to lose a long-term client. But I am just quite uncomfortable since the issue involves a lawyer.
Opinion or advice please.
