New York City Main Post Office Open Until Midnight

Ready for Last Minute Tax Filers

April 06, 2010 

Release No. NY01-22  

New York, NY – The James A. Farley Main Post Office at 421 Eighth Avenue between 31 and 33 Streets in Manhattan will be open until midnight on the evening of April 15 to assist last minute tax filers. For additional convenience mobile postal retail units will also be parked in front of the Post Office on Eighth Avenue with postal employees selling stamps and accepting mail.

Many New York City Post Offices throughout the five boroughs are regularly open until 7:00 p.m. or 8:00 p.m. on weeknights like April 15. Consumers can call toll free 1-800-ASK-USPS (1-800-275-8777) or go on-line to for the business hours and Post Office locations closest to their ZIP Code.

Postal officials offer the following mailing tips for tax-filers:

  • Make sure you have proper postage, especially if you have extra forms or schedules. The Internal Revenue Service (IRS) will not accept tax filings without postage or with insufficient postage. The IRS returns all tax filings with insufficient postage to the sender, who is then charged with late-payment penalties. It costs 44-cents for a one ounce letter and 17-cents for each additional ounce. One ounce is about four pages.
  • If you use a non-IRS labeled envelope, make sure you have the proper IRS address. Also, put your return address in the upper left-hand corner.
  • Mail early in the day if you can, so you can save yourself a trip to the late collection locations and avoid traffic and the last-minute rush.
  • Don’t use an office postage meter. The IRS doesn’t accept private postmarks as proof of timely filing.
  • If you are depositing a tax return on April 15th in a blue Post Office Collection Box, be sure to mail it before the last collection time posted on the box.
  • The Postal Service recommends getting the security of proof-of-mailing and proof-of-delivery of your tax returns -- use Certified Mail service ($2.80) with a Return Receipt ($2.30), plus the applicable postage.
  • Tax forms are no longer available at Post Offices. Check at local libraries or online at (Federal forms) or (NYS forms).
  • Stamped packages weighing more than 13 ounces must be presented in person to a Post Office clerk to comply with FAA regulations.

A self-supporting government enterprise, the U.S. Postal Service is the only delivery service that reaches every address in the nation, 150 million residences, businesses and Post Office Boxes. The Postal Service receives no direct support from taxpayers. With 36,000 retail locations and the most frequently visited website in the federal government, the Postal Service relies on the sale of postage, products and services to pay for operating expenses. Named the Most Trusted Government Agency five consecutive years and the sixth Most Trusted Business in the nation by the Ponemon Institute, the Postal Service has annual revenue of more than $68 billion and delivers nearly half the world’s mail. If it were a private sector company, the U.S. Postal Service would rank 28th in the 2009 Fortune 500.
