Common mistakes to avoid

  • Confusing OID with regular interest income reported on Form 1099-INT
  • Not reporting OID annually even though no cash interest was received during the year
  • Failing to adjust the cost basis of the instrument for OID already reported as income
  • Overlooking the de minimis OID rule, which allows small amounts of discount to be treated as zero

Do I have to report OID even if I did not receive any cash interest?

Yes. Original issue discount is considered taxable interest income that accrues annually, regardless of whether you receive any cash payments. You must report the OID shown on Form 1099-OID on your tax return each year. The amount increases your cost basis in the instrument, which reduces the gain (or increases the loss) when you sell or redeem it.
