I'm the PoA for a dementia patient, and had to file an extension for her taxes earlier this year because she'd thrown out or hidden all her tax documents. (Next year, everything will come directly to me, but for 2018 it was too late.) I've gotten replacements for everything but Social Security, but they won't talk to me because they don't recognize POAs. I belatedly learned that there's some sort of drawn-out application process to become the "representative payee," involving an appointment at the SSA office (in her state of residence, which is 2000 miles away from mine), followed by a review process; once that's complete, I could request one the replacement form, but I don't have time to do that before the deadline. I initially planned to go online and set up an account in my relative's name, and then download the form that way -- but it's illegal to set up an online account in anyone's name other than your own. I realize I should have figured this out before this, but spent most of this year dealing with her surgery and treatments for advanced cancer (while working full time and making repeated trips to her home state to take her to doctor's appointments, to stay with her in the hospital after surgery, to move her to a new apartment, etc. and, frankly, I was so fried I just haven't gotten to her taxes till now.) Any suggestions so she doesn't get penalized? Thanks!
