Form 1099-OID 2021 Tax Year Checklist
Purpose and Reporting Scope
Form 1099-OID reports original issue discount, market discount, acquisition premium, bond premium, and early withdrawal penalties for taxable and tax-exempt obligations held during 2021. Payers must report covered security treatment applicable to debt instruments acquired on or after January 1, 2014, for taxable obligations and on or after January 1, 2017, for tax-exempt OID reporting.
Filing Deadlines and Distribution Requirements
Payers must furnish Copy B to recipients by January 31, 2022. Copy A must be filed with the IRS by February 28, 2022, if filing on paper, or by March 31, 2022, if filing electronically using Publication 1220 specifications.
Nominee Reporting Obligations
You must verify that the recipient is not a nominee before filing. If you are the record holder for another person, you must complete a separate Form 1099-OID for each beneficial owner and file these forms with Form 1096, listing yourself as the filer.
A spouse is not required to file a nominee return to show amounts owned by the other spouse. Nominee reporting applies when you hold obligations on behalf of the actual beneficial owner.
Box-by-Box Reporting Requirements
Box 1 - Taxable Original Issue Discount
Report Box 1 only if the obligation has a stated redemption price exceeding the issue price. You must consult Publication 1212 for the appropriate OID amount under constant yield rules applicable to both covered and noncovered securities.
Box 2 - Qualified Stated Interest
Enter Box 2 separately from Box 1 and do not combine these amounts. If the recipient held the obligation for the entire 2021 calendar year, you must report the full amount as interest income.
For obligations sold or acquired mid-year, you must allocate the interest per Publication 550 guidance updated for 2021 to reflect only the recipient's holding period. Qualified stated interest represents periodic payments specified in the debt instrument.
Box 3 - Early Withdrawal Penalty
Complete Box 3 for any interest or principal forfeited on deposit accounts redeemed before maturity in 2021. Recipients deduct this amount as an above-the-line adjustment to income, and you must not reduce the amounts in Boxes 1 and 2 by the penalty amount.
Box 4 - Backup Withholding
Report Box 4 only if backup withholding was required under 2021 regulations. You must include TIN verification documentation and the recipient's TIN status per Form W-9.
Box 5 - Market Discount
For covered securities acquired with market discount, you must report accrued market discount on a constant yield basis unless the recipient notified you in writing per Regulations section 1.6045-1(n)(5) that they elected not to use the constant yield method. Brokers must use the constant yield method as the default reporting approach when the Section 1278(b) election applies.
Box 6 - Acquisition Premium
Report Box 6 for covered securities acquired with a premium in 2021 or earlier years. Payers must report either net OID reflecting the premium offset or gross OID and gross premium separately.
You must not report net amounts if you elected the gross reporting method. For tax-exempt obligations that are covered securities acquired before January 1, 2017, reporting the acquisition premium is optional.
Box 8 - Treasury Obligation OID
Complete Box 8 for Treasury obligation OID accrued in 2021, as this amount is exempt from state and local income tax and must be reported separately from Box 1. If the number in Box 8 is negative due to a deflation adjustment, recipients must note this per Publication 550 for Treasury inflation-protected securities.
Box 10 - Bond Premium Amortization
Report Box 10 for taxable covered securities acquired at a premium unless the recipient filed a written opt-out under Regulations section 1.6045-1(n)(5). The box amount reduces the interest reported in Box 2, and you must leave this box blank if you reported a net amount of interest in Box 2 that already reflects the premium offset.
Box 11 - Tax-Exempt OID
Enter Box 11 only for tax-exempt obligations that are covered securities acquired on or after January 1, 2017, with OID. Reporting is optional for tax-exempt obligations that are covered securities acquired before January 1, 2017.
Nonresident Alien Recipient Requirements
If the recipient is a nonresident alien, you must withhold and file Form 1042-S per Publication 515 foreign income tax withholding rules. You must not file Form 1099-OID for nonresident alien recipients, as Form 1042-S satisfies the reporting requirement for U.S. source income paid to foreign persons.
FATCA Reporting Considerations
The FATCA filing requirement checkbox reflects Chapter 4 account reporting obligations for 2021. If you check this box, the recipient may have separate Form 8938 filing requirements under FATCA rules.
You must check the box if you are a U.S. payer reporting on Form 1099 as part of satisfying your requirement to report with respect to a U.S. account for chapter 4 purposes. Foreign Financial Institutions must also check the box when reporting payments to U.S. accounts pursuant to specific elections.
Treasury Inflation-Protected Securities
Treasury inflation-protected security deflation adjustments appear as negative OID in Box 8 and become more prevalent in 2021. Recipients must account for these adjustments using Publication 550 methodology without reducing gross OID.
Market Discount Accrual Methodology
Market discount accrual calculation for covered securities uses the mandatory constant yield basis unless the recipient has elected a written opt-out. Payers must notify recipients of election deadlines in the Form 1099-OID instructions.
