Organizations acting as trustees or custodians of Health Savings Accounts (HSAs), Archer Medical Savings Accounts (Archer MSAs), and Medicare Advantage MSAs (MA MSAs) carry specific annual reporting obligations. Form 5498-SA serves as the official record submitted to the Internal Revenue Service and furnished to account participants to document account contributions, rollovers, and end-of-year fair market value. Unlike individual tax returns, this information return requires strict adherence to institutional reporting guidelines, separating calendar-year deposits from subsequent-year designations and distinguishing between reportable rollovers and excluded direct transfers.
According to the official Instructions for Forms 1099-SA and 5498-SA, trustees must ensure accurate box assignments to avoid systemic matching errors. This overview details the technical requirements for the 2026 reporting cycle, executed in early 2027, focusing entirely on the issuer's data preparation and submission responsibilities.
Filing and Furnishing Deadlines
Organizations must file Form 5498-SA with the IRS and furnish a corresponding statement to the participant by May 31 of the subsequent year. If May 31 falls on a Saturday, Sunday or applicable legal holiday, the deadline advances to the next business day. For 2026 reporting, file and furnish by Tuesday, June 1, 2027 because May 31 is Memorial Day. Trustees should note a critical distinction between agency filing and participant furnishing: while organizations may request an automatic 30-day extension to file with the IRS by submitting Form 8809, this extension applies solely to the IRS transmission. Form 8809 does not extend the deadline for furnishing the statement to the account participant. Timely delivery of participant statements is required regardless of IRS filing extensions.
Box-by-Box Reporting Requirements
Trustees must follow strict guidelines for categorizing deposits. Misreporting Box 3 amounts as next-year contributions is a common error; Box 3 actually captures deposits made in the following year that apply retroactively to the reporting year.
| Box Number | Data Field | Official Reporting Rules |
|---|---|---|
| Box 1 | Archer MSA Employee Contributions | Report employee or self-employed regular contributions to Archer MSAs only. Do not report any HSA information in this box. |
| Box 2 | Total Contributions in Calendar Year | Report total HSA/Archer MSA contributions received during the calendar year, including prior-year designations and IRA-to-HSA qualified funding distributions. |
| Box 3 | Contributions Made in Subsequent Year | Report contributions received in the subsequent year (through April 15) specifically designated for the reporting calendar year. |
| Box 4 | Rollover Contributions | Report received rollovers. Exclude direct trustee-to-trustee transfers. |
| Box 5 | Fair Market Value | Report the account's fair market value as of December 31 of the calendar year. |
| Box 6 | Account Type Checkbox | Indicate whether the account is an HSA, Archer MSA, or MA MSA. |
Rollovers Versus Direct Transfers
A frequent source of issuer confusion involves the movement of funds between accounts. For Form 5498-SA reporting, contributions and rollovers do not include standard trustee-to-trustee transfers. If an organization executes a direct transfer from one HSA to another HSA, or from an Archer MSA to an HSA, those amounts are excluded from Box 4 reporting. Conversely, true rollovers received by the trustee during the calendar year must be reported in Box 4. A distinct exception exists for qualified HSA funding distributions, which are trustee-to-trustee transfers from an Individual Retirement Arrangement (IRA) to an HSA under section 408(d)(9); these specific transfers are reported as total contributions in Box 2.
Fictional Business Numerical Example
To illustrate proper box assignment, consider a fictional scenario involving institutional issuer Meridian Custodial Trust preparing a 2026 Form 5498-SA for an HSA participant. During the 2026 calendar year, the participant deposited $3,200 via direct ACH. Additionally, the participant initiated a valid 60-day rollover of $1,500 from a previous HSA, which Meridian received in October 2026. In February 2027, the participant deposited an additional $400 specifically designated for the 2026 tax year. On December 31, 2026, the account's fair market value (FMV) stood at $5,150.
Meridian Custodial Trust would report this as follows: Box 1 is left blank because the account is an HSA, not an Archer MSA. Box 2 contains $3,200, representing the total contributions made during the calendar year. Box 3 contains $400, representing contributions made in the subsequent year for the calendar year. Box 4 contains $1,500 for the rollover. Box 5 reflects the $5,150 FMV. Finally, Box 6 will have the HSA checkbox marked.
Zero Contributions and Statement Exceptions
If a total distribution was made from an HSA or Archer MSA during the year and no contributions were made, trustees are generally not required to file Form 5498-SA or furnish a statement reflecting a zero FMV. However, if an account remains open with zero contributions but holds a balance, the trustee must still file the form with the IRS to report the December 31 FMV. If the trustee already furnished an FMV statement to the participant by the adjusted January 31 date of the subsequent year and no reportable contributions were made, they do not need another statement at the adjusted May deadline. The January furnishing date also moves to the next business day for a weekend or applicable legal holiday; for 2026 reporting, it is Monday, February 1, 2027 because January 31 is Sunday. The January FMV statement must contain a specific legend designating which information is being furnished to the IRS.
Handling Mistaken Distributions and Closures
When a participant repays a mistaken distribution to an HSA due to a reasonable mistake of fact, the trustee is not obligated to allow the return of funds. If the organization does allow the repayment, the amount must not be treated as a contribution on Form 5498-SA. Separate regulations under the USA PATRIOT Act dictate that if an HSA is closed by the trustee due to a failure to satisfy Customer Identification Program requirements, specific reporting applies. If regular contributions were made to the closed HSA and distributed back to the participant, the trustee must still issue a Form 5498-SA for any rollover contributions received before closure.
E-file Thresholds and TIN Truncation
Organizations filing 10 or more information returns in aggregate must file electronically. The IRS Information Returns Intake System (IRIS) provides a modern portal for this requirement. When preparing payee statements, trustees may truncate a participant's Taxpayer Identification Number (TIN) by masking the first five digits with asterisks or Xs. However, truncation is strictly prohibited on the actual forms transmitted to the IRS. Furthermore, a trustee's own TIN may never be truncated on any payee statement or IRS filing.
Frequently asked questions
Should trustees report an IRA to HSA transfer on Form 5498-SA?
Yes. Qualified HSA funding distributions, which are trustee-to-trustee transfers from an IRA to an HSA, are required to be reported by the receiving trustee in Box 2 as total contributions.
Does Box 3 report contributions intended for the following tax year?
No. Box 3 reports contributions received in the subsequent year (usually before April 15) that are specifically designated for the reporting calendar year. It does not report contributions meant for the next tax year.
Are direct trustee-to-trustee HSA transfers included in Box 4 rollovers?
No. For Form 5498-SA reporting purposes, direct trustee-to-trustee transfers between HSAs are excluded and should not be reported as rollover contributions in Box 4.
Can Form 8809 extend the deadline to mail payee statements?
No. Form 8809 provides an automatic 30-day extension to file information returns with the IRS, but it does not extend the deadline for furnishing statements to account participants.
Are participant repayments of mistaken distributions reported as contributions?
No. If a trustee allows a participant to repay a mistaken distribution based on a mistake of fact, that repayment must not be treated or reported as a contribution on Form 5498-SA.
The filing and furnishing adjustments follow IRS Publication 1099. The 2027 federal holiday schedule identifies May 31 as Memorial Day.
