2018 Tax Filing Dates and Important Deadlines for Colorado

You know what they say – death and taxes are the only two things guaranteed in life. Like it or not, no one is exempt from taxes, but on the bright side, your team at Yeater & Associates is here to help keep you on track so you can worry about the more important things in life.

Today, we’d like to put out a friendly reminder of important 2018 Colorado tax filing dates and deadlines to keep you from getting behind schedule.

2018 Income Tax Filing Deadlines

First off, let’s start with the basics that should be on everyone’s radar:

April 17, 2018 – Income tax filing deadline for 2017 Colorado State Tax Returns

Keep in mind the usual deadline for individuals and corporations filing income tax returns is April 15. For calendar year companies, this date typically is on or around Emancipation Day, which can impact the deadline. (Emancipation Day is April 16, but the government recognizes it on a Friday if that day happens to fall on a Saturday, or Monday if it lands on a Sunday.)

April 17, 2018 – Due date for Colorado automatic tax extensions

This date also serves as the deadline for the automatic tax extension. In Colorado, taxpayers do not have to fill out a form to receive this extension; it is automatically granted to them and they will only be responsible for interest fees.

Oct. 15, 2018 – Deadline for Colorado tax extension

Mark your calendars, because this date is right around the corner! The extended due date for corporate and individual taxes will be October 15, 2018. This is the final date for extension filers or e-filers to pay income taxes in Colorado.
