Last-minute tax filers have a few options to obtain the coveted April 15th Postmark.  

Properly stamped envelopes can be deposited at the blue collection box at the Boulder Valmont Station, 2995 55th St., until 7 p.m.  Apr. 15.

Additionally, returns with the proper postage can be deposited in the blue collection boxes outside the Longmont Main Post Office, 201 Coffman St. until midnight.

All area offices will maintain normal retail hours. No office will be staying open late.

However, the Denver General Mail Facility Post Office, at 7500 E. 53rd , near Quebec, will offer both retail services and return drop-off until midnight.

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

Last year, taxpayers filed more than 234 million income tax returns. Almost one-quarter of those were mailed.

Below are important tax mail tips.

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 www.irs.gov

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