State of Colorado Business Income Tax Extensions – Tax Year 2010
E-file an IRS business tax extension with FileLater.
| GENERAL INSTRUCTIONS |
|
An automatic six-month extension of time for filing the Colorado corporation income tax return is allowed for all taxpayers. However, an extension of time to file is not an extension of time to pay the tax. If at least 90 percent of the net tax liability is not paid by the original due date of the return, penalty and interest will be assessed. If 90 percent or more of the net tax liability is paid by the original due date of the return and the balance is paid when the return is filed by the last day of the extension period, only interest will be assessed. |
