Those wanting to avoid the crowds are encouraged to mail their tax returns early in the day. Correct postage is a must. First-Class letter-size postage is 49 cents for the first ounce and 21 cents for each additional ounce. If you use a larger envelope, First Class postage is 98 cents for the first ounce and 21 cents for each additional ounce. Customers wanting certification that their tax forms are received by the IRS, should mail them using Certified Mail Service.
Postal customers are encouraged to check the collection times posted on each box to ensure pick up on April 15. Stamps can always be purchased through Self-Service Kiosks, which accept debit and credit cards, and alternate locations, such as grocery stores and ATMs.
