The PSO (public safety officers) provisions are expanded and include private firefighters and corrections officers. There are many provisions that apply to 2022 and even retroactive to 2021. Example: Roth 401(k) employer match can also be to the Roth, starting for tax year 2022. You can establish a Solo 401(k) up to the due date of the return (not limited to the calendar year) for tax year 2023. RMDS are triggered at 73 yo in 2023 and moves to 75 in 2033. Roth 401(k) RMD will be eliminated in 2024. RMD penalty changes from 50% to 25% in 2023.

And of course, some details are yet to be defined.
