The boxes, one page each
Each row links to the page that reads that box. The right column is a line from the recipient copy of the form. Interest from banks and brokers on Form 1099-INT is covered on the 1099-INT box 1 page.
| Page | What the recipient copy says |
|---|---|
| Form 1099-OID box 1 | “Shows the OID on a taxable obligation for the part of the year you owned it.” |
| Form 1099-OID box 2 | “Shows qualified stated interest on this obligation for the year” |
| Form 1099-OID box 6 | “For a taxable covered security, shows the amount of acquisition premium amortization for the year that reduces the amount of OID” |
| Form 1099-OID box 8 | “Shows OID on a U.S. Treasury obligation for the part of the year you owned it.” |
| Form 1099-OID box 10 | “For a taxable covered security, including a Treasury inflation-protected security, shows the amount of premium amortization allocable to the interest” |
What original issue discount is
The recipient copy defines it: “Original issue discount (OID) is the excess of an obligation’s stated redemption price at maturity over its issue price”. It adds that “OID on a taxable obligation is taxable as interest over the life of the obligation.”
Edition this guide follows
Form 1099-OID has one edition on irs.gov, Rev. January 2024, and it was the one served as current on 2026-10-17. These pages read it, the Instructions for Forms 1099-INT and 1099-OID (Rev. January 2024) and Publication 550 for 2025 returns. The “For calendar year” line on your own form shows the year.
What is not covered here
Boxes 3, 4, 5, 7, 9 and 11 to 14 have no page of their own here. Interest reported on Form 1099-INT has its own pages, starting with the 1099-DIV, 1099-INT and 1099-B guide.
Common mistakes
- Reporting only what you were paid. The recipient copy says that “you must generally include an amount of OID in your gross income each year you hold the obligation”.
- Treating box 1 as the final number in every case. The form says you “may have to figure the correct amount of OID to report on your return”.
- Putting Treasury OID in box 1. The form says box 8 “is not included in” box 1.
