In Harrisburg and Philadelphia, e-file for both state and federal returns also will be available. This year, taxpayers have an extra day to file since April 15 falls on a Sunday. All tax returns must be postmarked by April 16 to be considered timely. We are there to assist those who have waited until deadline day at various locations in addition to our 23 district offices, Secretary Williams said. District office locations can be found in the government listing of local phone books.
Electronic filing remains the fastest, easiest way to file.
