State tax filing
See the explanation of @ErnieS0 above.
Does the Colorado tax return compute a 4.40% tax rate?
Divide line 10 by line 9. Below see $1,177 divided by $26,718 = 4.40%
This Colorado Department of Revenue website states:
A TABOR income tax rate reduction results in either a larger refund, if the taxpayer over-withheld, or a smaller bill, if the taxpayer did not withhold enough or make enough estimated tax payments that year. The refund amount is different for each taxpayer, based on their unique income tax situation.
