Once again, the United States Postal Service will accommodate the parade of people pursuing a postmark proving punctual posting of their tax returns.

The good news, according to the IRS, is that Tax Day is Tuesday, April 17, this year, so you have a couple of extra days to file and mail your taxes. There are no tax forms available at Post Offices, but filers can get them at www.irs.gov.

The Postal Service encourages everyone to file or mail their returns soon. All area Post Office retail windows will be open with regular customer service hours. The only location staying open late will be the Denver GMF facility at 7500 E. 53rd place, which is open for business until midnight.

The following offices will postmark tax returns up to 12 midnight. There will be no retail services, but the collection boxes outside the office will be available for properly stamped envelopes.

Last year, taxpayers filed more than 234 million income tax returns. Almost one-quarter of those were mailed. Below are important tax mail 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 44 cents for the first ounce.
• For heavier returns, add  20 cents postage 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 is received by IRS, should mail it using Certified Mail Service - 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 location that offers late tax mail collection or pick-up.
• Customers with IRS tax questions can contact the IRS at 1-800-829-1040; or go to www.irs.gov
