Colorado's 4.4% Is Not What You Actually Pay
Colorado is one of the easier states to plan for. One flat rate, no brackets to track, no local income tax percentage layered on top. The rate you see quoted is still misleading, though, and in your favour for once.
The federal standard deduction flows straight through
Colorado builds its taxable income from your federal figures and conforms to the federal standard deduction rather than inventing a smaller one of its own. For 2026 that means $16,100 for a single filer comes off before the 4.4% applies. Plenty of states give you a standard deduction in the low thousands or none at all, so this is unusually generous.
The effect on the real number is large. A single freelancer with $75,000 of net profit ends up paying roughly $2,358 to Colorado, which is about 3.1% of what they earned, not 4.4%. If you have been budgeting 4.4% of gross for state tax, you have been setting aside around a third more than you need.
Denver charges a flat monthly tax with no income floor
Here is the part that catches people. Denver runs an Occupational Privilege Tax, usually called the head tax. Employees owe it once they earn $500 in a month from work in the city. Self-employed proprietors and partners have no minimum at all: you owe the $4 monthly business portion for each month you do business in Denver, whatever you earned.
It applies to anyone performing work in Denver regardless of how briefly, so a contractor who lives in Boulder and spends a few days a month on a downtown client is inside it. Sole proprietors with no employees file an annual return. Aurora, Glendale, Greenwood Village and Sheridan run their own versions.
Forty-eight dollars a year, and still worth getting right
The amount is almost comically small. The reason to care is that it comes with a registration and a filing, and the penalties for never having filed are not proportional to $48. It is the kind of obligation that sits quietly for four years and then turns up as a letter with interest attached.
Our calculator handles Colorado's state tax and does not include the head tax, since it depends on which cities you physically work in. Check your own position with Denver's treasury division if you work in the city at all.
