Tried this with a couple of forms in Alaska and they were rejected because the signature looked like a digital one. (Even though my digital signature is a scan of an actual signature)
I had this with the IRS. Someone hand reviewed the form and used a highlighter to highlight the two digital signatures that were identical (they were, but not placed exactly the same, so im surprised they noticed) and said “this is not a legal signature, please sign again in ink and return”.
The E-SIGN act says that e-signatures are valid, with the main caveat being both parties need to opt into doing business electronically. Unfortunately that doesn't mean that every agency must accept e-signatures.
