1 thought on “IRS Office Horsham”

  1. Stopped by the other day to retrieve forms and instructions. Office locked up tighter than a federal correction center (prison). What is up? Some folks have no access to tax information and need an office to retrieve the needed forms. What is the fix? As a federal facility, your building ultimately belongs to the people and you have us lockout. You may blame COVID, but you also say we are bigger than that. Again, what is the fix? I am referring to the Horsham, Pa. office facility. Another federal incompetence is a Post Office on York Road. Broken outdoor mailbox for weeks on end coupled with the lack of an American Flag missing off the post. I am requesting feedback with resolutions.
