IRS Office Portsmouth – 80 Daniel Street, Portsmouth, NH 03801

The Portsmouth IRS Office is located in the Thomas J. McIntyre Federal Building at Daniel Street. Being a busy downtown location, there are plenty of federal and non-federal offices alongside different types of businesses around the block. This Federal Building is named after Thomas James McIntyre (February 20, 1915 – August 8, 1992) who had been an American Lawyer and Politician. During his tenure, he served as a United States Senator in New Hampshire. The GSA had been looking for opportunities to dispose of the federal purposes this building served and as a result of that decision, vacating the building has started in 2016 fall. However, the IRS along with other federal offices namely The Federal Bureau of Investigation, US Postal Service, Social Security Administration and General Services Administration is operating their regular functions on this building. Despite being declared surplus to this building’s needs, it still serves a great service to the residents of Portsmouth city. Other tenants on this building are CrystalVision Inc., Caci Inc., Done Right Building Services, and WorldWide Digital Divide. Locations close to this Federal Building are St. John’s Episcopal Church, HubSpot Portsmouth Office, Warner House, Portsmouth Memorial, Bank of America Financial Center, North Church of Portsmouth, Strawberry Banke Museum, Liberty Gardens, Prescott Park, Moffatt-Ladd House & Garden etc.
