Harry Sit gets the numbers published early.
“The total employer plus employee contributions to all defined contribution plans by the same employer will increase by $1,000 from $57,000 in 2020 to $58,000 in 2021. The age-50-or-over catch-up contribution is on top of this limit. If you work for multiple unrelated employers in the same year, you have separate limits at each employer.”
Also: “The HSA contribution limit for single coverage will go up by $50 from $3,550 in 2020 to $3,600 in 2021. The HSA contribution limit for family coverage will go up from $7,100 in 2020 to $7,200 in 2021.”
