Brand new to investing outside of my employer 457b. I realized through PFC IG posts and podcasts I have too much in my savings account and want to invest the $6000 max in a Roth. I want to do this for 2021 and have the option to do so for 2022. I have read conflicting info and not sure if I need to invest before the calendar year ends, or the tax year ends to count for 2021.
Could I max out 2021 before January 1st, and then max out 2022 after January 1st?
Or is it max out 2021 before April 15th, and 2022 after April 15th.
Thanks so much for the help 
You have until end of the tax year. You can even specify after the calendar year which year you want contributions to go to.
At least I know with Fidelity they have it on their interface that you can choose which year you want to contribute to.
