Limited time offer at participating locations. If you file your individual income tax return on a calendar year basis and have a valid extension for 2021, then October 15 is the deadline to file your return. Since October 15 is a Saturday, file by October 17 to avoid the late filing penalty. Application for automatic extension of time to file U.S. individual income tax return is through Form 4868. Colorado law allows for an automatic six month extension for filing, unlike federal filing that requires you to proactively apply for extension by submitting a special form. Software DE, HI, LA, ND and VT do not support part-year or nonresident forms. You’re getting unlimited assistance from our CPAs and other tax experts. They’ll give you helpful tax advice in the moment of need and look over your taxes before you file. OBTP# B13696 ©2018 HRB Tax Group, Inc.
