However, Putnam strongly advised tax filers to do all they can to avoid the crowds of people who inevitably will wait until the last minutes to mail their returns by posting their returns early on April 15.
Reminders: 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.
If you do mail returns late on April 15, do so at the collection boxes located directly outside the Post Offices providing extended collection times.
Those who choose self-self-service kiosks can use credit or debit cards for postage and request a mailing label. Any label printed before midnight will receive the April 15 post mark.
