Last-minute tax filers? Northern Colorado Area Post Offices are ready


April 07, 2015 @USPS

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

On April 15, all area Post Office retail windows will be open for regular hours only.

We will not be staying open late.

However, if you absolutely must wait until the last minute to mail a return, the following offices will accept prepaid, prestamped tax returns for postmarking only. Drop the mail in the outside collection box before 12 midnight at these locations:

  • Colorado Springs Briargate Station, 8585 Criterion Dr.
  • Colorado Springs Cheyenne Mountain, 1540 S. 8th St.
  • Colorado Springs Cimarron, 5925 E. Galley Rd.
  • Colorado Springs General Mail Facility, 3655 E. Fountain Blvd.
  • Colorado Springs Templeton Station, 4356 Montebello Dr.


There will be no retail services, but the collection boxes outside the office will be available for properly stamped envelopes.

Customers can call 1-800-ASK-USPS (1-800-275-8777) to find out the regular customer service hours of their local Post Office.

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.
