The IRS said it is raising the maximum allowable contribution to a health savings account by $100 in 2016 — but only for families.

The IRS quietly announced last week that the maximum contribution that can be made next year to an HSA linked to a high-deductible plan will be $6,750 for employees with family coverage, up from $6,650 in 2015. The maximum contribution for those with single coverage, however, will remain unchanged at $3,350.
