I have past years I have made Colorado state estimated tax quarterly payments; however, my 2018 earnings situation has changed significantly. TurboTax helped me estimate that I will be paying a little less than $1,200 Federal income tax for 2018. I will have enough federal withholding from one of my income sources to cover this amount, so I will not be making federal estimated tax quarterly payments. However, I do not have any Colorado state taxes being withheld. Do I need to pay Colorado state estimated tax quarterly payments? If so, how do I decide how much to pay each quarter?
