Select Post Offices to Offer Extended Hours for Tax Filers

Tax Deadline Extended Until April 18, 2011

April 04, 2011 

Release No. SF11-011  

SAN FRANCISCO With more people filing their taxes online, fewer are mailing their returns through the U.S. Postal Service. For those last-minute filers, two Post Offices in the San Francisco Postal District will be extending retail hours, and three will be offering curbside drop-off service on Monday, April 18, 2011.

Because April 15, 2011, is a holiday in Washington DC, this year tax day, or the last day to file your 2010 federal and state tax forms without requesting an extension, is Monday, April 18, 2011. All tax filers are urged to plan well in advance of April 18, or they risk missing the midnight deadline.

Waiting until the last minute is usually not a good idea. Rushing can cause mistakes, and the most common errors Americans make are not including enough postage and not providing the correct IRS mailing address. Other common mistakes, according to the IRS: Social Security Numbers are wrong or left off, math errors and forgetting to attach forms and schedules, e.g., W-2s, 1099s, etc.

To help ensure a successful tax season for customers, the Postal Service offers the following tax mailing tips:

  • Apply proper postage and stamps, especially with extra forms/schedules. It costs 44 cents for the first ounce; 20 cents for each additional ounce. (One ounce is about four pages).
  • If you use a non-IRS labeled envelope, make sure you print the proper IRS address.
  • Print your return address in the upper-left-hand corner of your tax mail envelope.
  • Customers who wish certification that their tax mail form is received by the IRS should mail it using Certified Mail Service/Return Receipt, which is available at your local Post Office.
  • While encouraged to mail before April 18, if you do wait until late on Tax Day be sure to drop off your tax mail return at a Postal Service location that offers late tax mail pick-up.
