Most, but not all, states levy a tax on personal income<\/a>. Some states use a progressive tax that provides different tax brackets based on income levels, as does the federal government, but others have what is called a "flat" tax that applies to all taxpayers regardless of income. States that do not collect income tax typically make up for it in other ways, such as higher sales tax or special taxes on certain items. In any event, these revenues are used to pay for state infrastructure projects, education, police, and other public goods and services.<\/p>\r\n

Overview of Colorado Personal Income Taxes<\/h2>\r\n

Colorado collects a 4.63 percent rate on all federal taxable income, regardless of one’s income level. You must file a tax return in Colorado if, during the tax year, you were a full-time resident, part-time resident with taxable income during the time you were a resident, or a non-resident of the state with income from a Colorado source.<\/p>\r\n

How to File Income Taxes in Colorado<\/h2>\r\n

Taxpayers may file their tax returns either electronically or by mailing a completed form with supporting documents. This applies to individuals as well as businesses, which pay the same rate. According to the Colorado Income Tax Filing Guide<\/a> (PDF), you should complete your federal tax return first, since the state return uses numbers calculated on the federal return. In order to file online, click on the link for the appropriate tax year<\/a> and follow the step-by-step instructions. The state provides an index of printable tax forms and links<\/a> to its online service.<\/p>\r\n
