The following are tips for income tax filers mailing their returns:
If filing on April 15, mail early in the day at any Post Office. Be sure to verify Post Office hours of operation.
If depositing returns in a collection box on April 15, double check the pick-up schedule on the collection box. To ensure getting the April 15 postmark, deposit returns before the last scheduled pick-up time.
Affix the correct postage. Some returns include many forms and require additional postage. For letter-sized envelopes, one ounce is 49 cents; the second ounce is an additional 21 cents. If you use an 8 ½ X 11 envelope your postage is 98 cents up to one ounce and $1.19 for two ounces. Priority Mail is $5.60 at the retail counter and $5.05 via online services. The IRS will not pay postage due and will return items to sender.
In addition to the Post Office retail counter, postage may be purchased at a Self-Service
Kiosk (SSK) in many lobbies. For locations, visit usps.com. Alternate access locations to buy stamps i.e. grocery stores, also are listed at usps.com.
Remember that due to heightened security, mail that bears only postage stamps and weighs more than 13 ounces must be taken by the customer to a Post Office retail counter. Be sure to include a return address on your envelope. Verify the IRS address where your return should be mailed.
