No ACH enrollment means interest stops when CBP tries to pay
IEEPA refunds include interest under 19 U.S.C. 1505. There is a trap though.
Under 19 CFR 24.36(a)(3), amended via Federal Register 2025-24171: if CBP certifies the refund and initiates the transfer but cannot complete it because the recipient has no ACH banking info on file, interest stops accruing from that moment. Not when the issue gets fixed. From when CBP first attempted.
The refund sits in the REV-613 ACH Rejected Refunds report earning nothing.
At 6% annualized, that's roughly $1,000/month on a $200k refund.
Set up ACH before filing. Not after.
