Do I need to sign my 8453 form & mail in for PA State

[bluedeb · Accepted solution]

No, that is for your records you must keep.  The following is from your state

You must retain completed Forms PA-8453 and supporting documents for three years after the due date of the return or the date the return was filed electronically, whichever is later. EROs and transmitters must make the documents available to the PA Department of Revenue upon request. Do not mail Form PA-8453 and attachments to the PA Department of Revenue unless requested.
