Health Savings Accounts (HSAs) were created as a tax-favored framework to provide health care benefits mainly for small business owners, the self-employed, and employees of small to medium-size companies who do not have access to health insurance.
The tax benefits of HSAs are quite substantial. Eligible individuals can make tax-deductible (as an adjustment to AGI) contributions into HSA accounts. The funds in the account may be invested (somewhat like an IRA), so there is an opportunity for growth. The earnings inside the HSA are free from federal income tax, and funds withdrawn to pay eligible health care costs are tax-free.
An HSA is a tax-exempt trust or custodial account established exclusively for the purpose of paying qualified medical expenses of the participant who, for the months for which contributions are made to an HSA, is covered under a high-deductible health plan. Consequently, an HSA is not insurance; it is an account, which must be opened with a bank, brokerage firm, or other provider (i.e., insurance company). It is therefore different from a Flexible Spending Account in that it involves an outside provider serving as a custodian or trustee.
The recently released 2015 inflation-adjusted contribution limit for individual self-only coverage under a high-deductible plan is $3,350, while the comparable amount for family coverage is $6,650. For 2015, a high-deductible health plan is defined as a health plan with an annual deductible that is not less than $1,300 for self-only coverage and $2,600 for family coverage, and the annual out-of-pocket expenses (including deductibles and copayments, but not premiums) must not exceed $6,450 for self-only coverage or $12,900 for family coverage.
