HSA: Form 8889, 1099-SA, and 5498-SA

Why Form 8889 matters

Form 8889 reports HSA contributions, calculates a possible HSA deduction, reports distributions, and determines certain amounts that may need to be included in income.

The form can be required even when only an employer made contributions. HSA activity should therefore be identified separately when gathering tax documents.

1099-SA, 5498-SA, and W-2

Form 1099-SA reports distributions from an HSA. Form 5498-SA reports contributions, while employer HSA contributions are generally also shown on Form W-2, box 12, code W.

These forms serve different purposes. Receiving one of them does not mean the other HSA information can be ignored.

Qualified medical expenses

An HSA distribution used for qualified medical expenses is generally not taxable, but the distribution is still reported through Form 8889. Keep records showing how the funds were used.

The IRS instructs taxpayers to retain records showing that expenses were qualified, were not reimbursed from another source, and were not also taken as an itemized deduction. These receipts are generally kept with your records rather than attached to the return.

What to prepare

Gather Forms 1099-SA and 5498-SA, Form W-2 with HSA information, personal contribution records, and support for medical expenses paid from the HSA. Flag excess contributions, a repayment of a mistaken distribution, or changes in HSA eligibility during the year.
