Colorado is one of the eleven union states with a flat income tax rate of 4.4% for the 2023–2024 tax year. The state automatically extends taxes for six months, so anybody looking for extra time to file their taxes can take advantage of this perk with an April 15, 2024 deadline.

It is important to remember, nevertheless, that taxpayers must make sure they have paid at least 90% of their tax bill before the first filing date to avoid penalties and interest. Colorado citizens and non-residents making income inside the state's borders must comprehend these tax complexities.

Colorado's Standard Deduction

One way Colorado sets itself apart from the rest is that it does not have a state standard deduction for taxes. This variation results from the state's use of a person's federal taxable income as the primary factor in determining Colorado tax obligations. The use of the taxpayer's itemized deductions or the federal standard deduction is already factored into the federal taxable income. As a result, Colorado bases the amount of state taxes due on this federal taxable income.

Nevertheless, it's important to remember that certain single and joint filers with incomes over specified limits may have to consider some federal itemized deductions in determining their Colorado taxable income. Due to the additional complexity this adjustment brings, those in higher income categories will need to reevaluate how their deductions may affect their Colorado state tax obligations. Taxpayers are recommended to visit the Individual Income Tax Guide on the official website of the Colorado Department of Revenue for detailed explanations and information on how this applies.
