I was told that to handle IRS documents for my mom I should fill out form 2848. But, I see that it just authorizes an accountant to do so. What about the forms I am filling out on her behalf to hire a caregiver...Employer Identification number, etc. and filing taxes for the employee, etc. I can't see how this form helps me to do that. Is there another form I should use? I have a financial POA, but have heard it is not enough for the IRS and they have their own form.
