As it does each year, the IRS has announced changes for health savings accounts, which are associated with high-deductible health plans.
The figures for 2022:

Self-only: $3,650 (a $50 increase from 2021).
Family: $7,300 (a $100 increase from 2021).

According to the Society for Human Resource Management, the government bases its decision on the Consumer Price Index for All Urban Consumers for the 12-month period ending on March 31.
The IRS has made a similar adjustment to maximum out-of-pocket amounts:

Self-only: $7,050 (a $50 increase from 2021).
Family: $14,100 (a $100 increase from 2021).

The catch-up contribution amount for those 55 and older is not automatically adjusted and remains at $1,000.
Also remaining the same are minimum deductibles:

Self-only: $1,400.
Family: $2,800.
