- Uniform Lifetime Table updated to 2022 revision. This affects Required Minimum Distributions from retirement accounts for 2022 and beyond.
- The model used to estimate future Medicare B premium was updated to index income bracket thresholds to inflation except for the top bracket. The top bracket will be held at the current value. This extends the pattern of updates to the Medicare B income thresholds in recent years. This can mean the lower brackets may collapse into the top bracket over time depending on the inflation setting. At the point a lower bracket rises to meet the top bracket, the top premium level is used if the AGI is at or above the current top bracket.
