Distributions from HSAs 
1. When is an individual permitted to receive distributions from a HSA?
At any time.
2. How are distributions from a HSA taxed?
Distributions from a HSA used exclusively to pay for qualified medical expenses of the account beneficiary, his or her spouse, or dependents are excludable from gross income. In general, amounts in a HSA can be used for qualified medical expenses and will be excludable from gross income even if the individual is not currently eligible for contributions to the HSA. However, any amount of the distribution not used exclusively to pay for qualified medical expenses of the account beneficiary, spouse or dependents is includable in gross income of the account beneficiary and is subject to an additional 10% tax on the amount includable, except in the case of distributions made after the account beneficiary's death, disability, or attaining age 65.
3. What are the "qualified medical expenses" that are eligible for tax- free distributions?
The term "qualified medical expenses" are expenses paid by the account beneficiary, his or her spouse or dependents for medical care as defined in section 213(d) (including nonprescription drugs as described in Rev. Rul. 2003-102, 2003-38 I.R.B. 559), but only to the extent the expenses are not covered by insurance or otherwise. The qualified medical expenses must be incurred only after the HSA has been established. For purposes of determining the itemized deduction for medical expenses, medical expenses paid or reimbursed by distributions from a HDHP are not treated as expenses paid for medical care under section 213.

4. Are health insurance premiums qualified medical expenses?
Generally, health insurance premiums are not qualified medical expenses except for the following: qualified long-term care insurance, COBRA health care continuation coverage, and health care coverage while an individual is receiving unemployment compensation. In addition, for individuals over age 65, premiums for Medicare Part A or B, Medicare HMO, and the employee share of premiums for employer-sponsored health insurance, including premiums for employer-sponsored retiree health insurance can be paid from a HSA. Premiums for Medigap policies are not qualified medical expenses.
5. How are distributions from a HSA taxed after the account beneficiary is no longer an eligible individual?
If the account beneficiary is no longer an eligible individual (e.g., the individual is over age 65 and entitled to Medicare benefits, or no longer has a HDHP), distributions used exclusively to pay for qualified medical expenses continue to be excludable from the account beneficiary's gross income.
6. Must HSA trustees or custodians determine whether HSA distributions are used exclusively for qualified medical expenses?
No. HSA trustees or custodians are not required to determine whether HSA distributions are used for qualified medical expenses. Individuals who establish HSAs make that determination and should maintain records of their medical expenses sufficient to show that the distributions have been made exclusively for qualified medical expenses and are therefore excludable from gross income.
