Colorado Income Tax Brackets

The above table provides you with a broad range of different Colorado income tax bracket scenarios. The income tax calculator used in the table above is based on a single taxpayer (not married) claiming one personal exemption.

The Colorado State income tax rates in the table reflect almost a worst-case scenario for a US taxpayer because those that are married and have dependents can typically take advantage of other deductions, which would effectively make the federal income tax you pay, less than what you see in the table.

Again, you should always consult a professional when it comes to calculating your Colorado tax liability, since other factors may affect the amount of income tax you pay on your earnings in Colorado. The Colorado income tax bracket is fixed at 4.63% as noted on the table, but you are still responsible for paying Social Security (6.2%) and Medicare (1.45%), totaling 7.65%.

You are also responsible for paying Federal Income Tax regardless of whether you reside in Colorado with its low and fixed 4.63% income tax rate.
