Where can I find my IRS payment confirmation number?

Full answer

Your payment confirmation number usually appears on the final acknowledgment screen after you submit an electronic payment, so save or print that page right away. If you chose email confirmation, check your inbox and spam folder.

EFTPS gives each payment its own EFT acknowledgment number, and authorized card processors give their own confirmation number — the two look different. A bank reference number is not an IRS confirmation number.

For Form 2290, your filing acceptance (the stamped Schedule 1) and your tax payment confirmation are separate records for separate transactions. If you cannot find the number, check the payment service you used, your payment emails and receipts, and your EFTPS payment history.
