The IRS has released the 2015 inflation-adjusted amounts for health savings accounts (HSAs) and high-deductible health plans (HDHPs). 

HDHP Minimums and Maximums. The minimum annual deductible for an HDHP will increase to $1,300 for self-only coverage and $2,600 for family coverage. The maximum annual out-of-pocket for an HDHP will increase to $6,450 for self-only coverage and $12,900 for family coverage.

Relationship to ACA Maximum Out-of-Pocket. The Affordable Care Act also sets out-of-pocket maximums for non-grandfathered plans. For 2014, the ACA maximum and the HDHP maximum are the same. But the amounts are indexed at different rates, and for 2015 they will be different. The ACA maximum will be $6,600 for self-only coverage and $13,200 for family coverage (compared to $6,450 and $12,900 for HDHPs). What does this mean? A plan designed to satisfy the ACA maximums will not necessarily qualify as an HDHP. It will need to satisfy the lower maximum applicable to HDHPs. 

Maximum HSA Contribution. The maximum annual contribution to an HSA for 2015 will increase slightly to $3,350 for an individual with self-only HDHP coverage and $6,650 for an individual with family HDHP coverage. Catch-up contributions for individuals age 55 and older are not inflation-adjusted and remain at $1,000 per year.

Recall that these annual maximums are prorated on a monthly basis for an individual who is covered under an HDHP for less than the full year. Also, special rules apply when one or both spouses have HDHP coverage, with the general effect of limiting the household to a single family-level HSA contribution for the year.
