Form 104X is a Colorado Individual Income Tax form. An amended tax return is used to correct errors or omissions in a previously-filed tax return. While taxpayers will not generally be punished simply for correcting an error in a previous return, errors that resulted in an underpayment of owed tax can sometimes result in penalties or interest owed.
About the Individual Income Tax
The IRS and most states collect a personal income tax, which is paid throughout the year via tax withholding or estimated income tax payments.
Most taxpayers are required to file a yearly income tax return in April to both the Internal Revenue Service and their state's revenue department, which will result in either a tax refund of excess withheld income or a tax payment if the withholding does not cover the taxpayer's entire liability. Every taxpayer's situation is different - please consult a CPA or licensed tax preparer to ensure that you are filing the correct tax forms!
