The IRS recently published the annual inflation updates for 2021. If you have questions about a particular amount that I do not mention here, you can likely find it in the official IRS announcements:
- Rev. Proc. 2020-45 contains most inflation adjustment figures, and
- Notice 2020-79 contains figures relating to retirement accounts.
