Get your taxes done using TurboTax

@dazed-&-confused The bank should have reported both, whether on the same or separate 1099-INTs; the $10 IRS threshold is per person, NOT per account. In your example, the 33 cents will be ignored anyway as it rounds to zero (TurboTax always rounds to the nearest dollar where allowed by the IRS) and the reported account is an even dollar amount; but if it plus the cents on the 1099-INT add up to 50 cents or more it will round up. If you're sure the 33 cents isn't included in the $12 and there is no backup withholding, it's best to add them together; the IRS doesn't match most individual 1099-INTs like they do W-2s. If there's backup withholding on either, report them separately; a 1099-INT is supposed to be issued regardless of amount if there's ANY backup withholding, and that case may require individual form matching.
