I didn’t get a 1099-INT because the interest earned was less than $10—do I still need to report it on my tax return?

I recommend reporting it because it helps to look for it next year.  If I see it on last year’s tax return, I’ll ask what happened to it for this year.  If I don’t see it, then I won’t ask for it. In most cases, it will not increase your income tax much if you do report it. As always, it’s up to you whether you want to provide the year-to-date interest amount if it’s less than $10.00.
