With the deadline for filing income tax returns rapidly approaching, the U.S. Postal Service is bracing for last-minute filers.

The last day to file 2015 federal tax forms without requesting an extension is Monday, April 18. To aid last-minute filers, mail will be collected until midnight at the lobby mail slot at the Kalispell Main Post Office, 350 N. Meridian Road.

Tax-day mailing tips

• Apply proper postage and stamps, especially with extra forms/schedules. It costs 47 cents for the first ounce. The price for additional ounces is 21 cents each. One ounce is about four pages, but since paper weights vary, it’s always best to check or play it safe and add a stamp.

• If you use a non-IRS-labeled envelope, make sure you print the proper IRS address.

• Customers with tax questions can contact the IRS at 1-800-829-1040 or www.irs.gov.
