About these Colorado figures: state tax here is calculated from a compiled 2025/2026 rate table using each jurisdiction's brackets and standard deduction — not from Colorado's own published schedule, and not every entry has been confirmed against it. Treat the result as an estimate and check anything you are relying on with Colorado's revenue department. Federal figures come from published IRS releases and are cited on the pages that use them.

What Is a 1099 Tax in Colorado?

No employer withholds tax from a 1099-NEC, so a Colorado contractor settles the whole bill themselves. Worked through on $75,000 of net freelance income, the three pieces come out like this:

Self-employment tax — $10,597: 15.3% covering Social Security and Medicare, charged on 92.35% of net earnings. Federal, so it is the same in Colorado as anywhere else.
Federal income tax — $4,898: what remains after deducting half your self-employment tax and the $16,100 standard deduction, then running the 2026 brackets.
Colorado income tax — $1,887: 2.52% of your gross income once Colorado's brackets and deductions are applied, which is 11% of everything you owe and ranks Colorado 30 of 51 nationally.

That totals $17,382, an effective rate of 23.2%, leaving $57,618 once Colorado has taken its share.
