With tax season on the way (more info here), you can find the 2015 tax rates here. Remember that these are the rates that you’ll use to file your 2015 tax returns by April 18, 2016 (Tax Day is delayed this year).
You’ll use the 2016 tax rates for tax planning in 2016 and to file your 2016 tax returns in 2017. Confusing, I know.
