Last-minute tax filers are likely to have one more item on their checklist – how to secure a coveted April 15th Postmark.

All area Post Office retail windows will maintain regular customer service hours with the exception of one office --, the Denver General Mail Facility office at 7500 E. 53rd Place will be open until midnight.

With the exception of this one location, we will not be staying open late.

The following will not have extended retail services, but the collection boxes outside the office will be available for properly stamped envelopes until midnight. At all of these locations, there are self-service stamp kiosks for stamp purchases. Customers who arrive after the window closes can still purchase stamps at the kiosk and place the returns in the outside mailbox before midnight at these

Tax Mailing tips:

  • Apply the proper postage or stamps, especially if enclosing extra forms and schedules. Using a regular size Number 2 envelope, First Class postage costs 49 cents for the first ounce.
  • For heavier envelopes, add extra stamps or postage amounting to 21 cents for each additional ounce.
  • If you are not sure about the correct postage, it is best to add additional stamps, or take your forms to the Post Office to ensure that correct postage is applied.
  • Make sure you print the proper IRS address on the front of the envelope. 
  • Print your return address in the upper-left-hand corner of your tax mail envelope.
  • Customers who wish certification that their tax mail form was sent, should send it Certified Mail
  • Customers with IRS tax questions can contact the IRS at 1-800-829-1040; or go to


The Postal Service receives no tax dollars for operating expenses and relies on the sale of postage, products and services to fund its operations.
