It's never too early to start thinking about your next tax return. For most Americans, that'll be your federal tax return for the 2020 tax year — which, by the way, will be due on April 15, 2021 (or October 15, 2021, if extended). The 2020 tax rates themselves are the same as the rates in effect for the 2019 tax year: 10%, 12%, 22%, 24%, 32%, 35% and 37%. However, as they are every year, the 2020 tax brackets were adjusted to account for inflation. That means you could wind up in a different tax bracket when you file your 2020 return than the bracket you were in before – which also means you'll be paying a different tax rate on some of your income.
