I'm sorry to piggyback on this old post, but I wanted to get a sense of how people are faring with using EFTPS & ID.me.  Several people in the firm already have ID.me accounts, but haven't made the plunge of paying clients payroll tax liabilities through EFTPS anymore due to the MFA fun.  Specifically, how do you best get permission pay your clients taxes on EFTPS now?  Is it best to get them to sign a 8655 Reporting Agent Authorization form?  It's also been suggested to have the client sign an IRS 2848 Power of Attorney form.  Not sure the best way to go about it. Your thoughts are most appreciated!!!
