TP received this IRS letter in the mail. I verified that banking info on the return was same as successfully used for last 3 years…. The letter goes on to say he has 30 days to update his banking info or create an account with id.me….(TP is 85YO so, not a chance. 

Does anyone know next step in IRS procedure? Will they mail a letter he can update or provide banking info? 

IMO, the issue is/was caused by his bank and he should have a ‘conversation’ with them. Concern is that even if he updates his info (with no changes) that it will happen again.
