When will extensions be available to file online???

[ErinH]

Continue checking back throughout the day as Easy Extension should be available very soon (expected today, but for sure by the end of March): https://turbotax.intuit.com/irs-tax-extensions/ 

Or you can download Form 4868 from the IRS website, print it out (4 pages), and mail it in before the deadline. Complete instructions are on the printout.
