I updated Tom's COLA spreadsheet with the actual July 2021 CPI-U, which is the first of the 3 CPI-U figures needed to determine the 2022 dollar limits. The July 2021 CPI-U was 273.003. Based on Tom's spreadsheet, assuming we have exactly 0% inflation in the CPI-U from August 1, 2021 through September 30, 2021, perhaps the 2022 limits might be:
Deferral limit: $20,500 (2021 is $19,500)
Compensation Limit: $305,000 (2021 is $290,000)
DC Annual Addition Limit: $61,000 (2021 is $58,000)
DB Benefit Limit: $245,000 (2021 is $230,000)
Key Employee: $195,000 (2021 is $185,000)
HCE: $135,000 (2021 is $130,000)
Unchanged:
Catchup Limit: $6,500
