For the last 2-3 years my daughters refund was processed late so IRS paid her an additional amount and followed up by sending a 1099 for that amount. Previously the amounts were between $12-$15. This year 2023 they overpaid for 2022 by $4.80 but so far she hasn't received a 1099 for that amount. My question is---Does the IRS not send a 1099 for under $10 like their ruling for FI's? She will include the $4.80 as income anyway, but didn't want to wait around for a 1099 that may never be coming. Thanks

IRS requires you to list and pay tax on any interest, including from IRS, even if below $10 and you have not recieved a 1099. IRS is definitely going to know that they gave you less than $10. I can't recall with certainty if they sent me a 1099 about that after paying me less thant $10 last year, but I think not.
