Form 1099-INT: What It Is and How to Report Interest Income


ANSWER SECTION

Form 1099-INT reports interest income of $10 or more paid to you by banks, credit unions, brokerages, and other financial institutions. The payer sends Copy B to you by January 31 and Copy A to the IRS. You must report this interest on your tax return—generally on Schedule B of Form 1040 if your total interest and dividends exceed $1,500, or directly on Form 1040 if below that amount.


H2: Who Issues Form 1099-INT

Financial institutions must issue Form 1099-INT if they pay you:

  • $10+ in interest during the calendar year
  • $600+ in interest in the course of their trade or business (different threshold)

Common payers include:

  • Banks and credit unions (savings accounts, CDs, money market accounts)
  • Brokerage firms (interest on cash balances, bond interest)
  • TreasuryDirect (interest on savings bonds)
  • Mortgage companies (interest refunds)

Key Form: Form 1099-INT (Interest Income)


H2: Understanding 1099-INT Box by Box

Box 1: Interest Income — Taxable interest you must report. Includes bank account interest, CD interest, and most bond interest.

Box 2: Early Withdrawal Penalty — Amounts you forfeited for early withdrawal from CDs. You can deduct this on Schedule 1, line 18.

Box 3: Interest on U.S. Savings Bonds and Treas. Obligations — Taxable at federal level but exempt from state tax.

Box 4: Federal Income Tax Withheld — Backup withholding applied to your interest. Report as tax paid on your return.

Box 8: Tax-Exempt Interest — Interest from municipal bonds. Reported but not taxed federally. May be taxed by your state if from another state.


H2: How to Report 1099-INT on Your Tax Return

If total interest + dividends ≤ $1,500: Report directly on Form 1040, line 2b (Taxable Interest).

If total interest + dividends > $1,500: File Schedule B (Interest and Ordinary Dividends) with your Form 1040. List each payer separately, then carry the total to Form 1040, line 2b.

Tax-exempt interest (Box 8): Report on Form 1040, line 2a. It affects certain tax calculations even though it is not taxed.


H2: Common 1099-INT Situations

Multiple accounts: You may receive several 1099-INT forms. Report each one. The IRS receives copies too, so underreporting triggers notices.

Joint accounts: The primary account holder typically receives the 1099-INT. If you split interest with a joint owner, each reports their share.

Inherited accounts: Interest earned before death goes on the decedent's final return. Interest earned after death goes on the estate or beneficiary's return.

Foreign accounts: Foreign bank interest is taxable and reportable on FBAR (FinCEN Form 114) if aggregate foreign accounts exceed $10,000.
