What your bracket means
Take a single filer earning $75,000. After deductions, $58,900 is taxable in Colorado. The top slice falls in the 4.4% bracket, but the total Colorado tax is $2,592, or 3.5% of the salary, because the lower slices are taxed at lower rates.
2026 federal tax brackets
Federal income tax comes off first. For 2026 the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly, and the brackets run from 10% to 37%. Pre-tax 401(k) contributions (up to $24,500) lower your federal and most state income tax, but not FICA.
