The instructions are in 2004 General Instructions for Forms 1099, 1098, 5498 and W-2G and available at the IRS Web site here .
The IRS has also replaced Forms 1099-MSA and 5498-MSA, the forms on which distributions from Archer, Medicare+Choice and Medicare Advantage Medical Savings Accounts (MSAs) are reported. Now those distributions, as well as those from HSAs, are to be made on two new forms:
- Form 1099-SA, used to report distributions from an HSA or an Archer or Medicare+Choice MSA
- Form 5498-SA, used to report contributions to an HSA and an Archer MSA, as well as the fair market value of an HSA, Archer MSA or Medicare+Choice MSA.
Forms 1099-SA and 5498-SA are not yet available. Nonetheless, the IRS has warned that filers should not use Forms 1099-MSA and 5498-MSA to report distributions or contributions made for 2004. The IRS said that the new forms will be available later this year.
