How do I get proof of payment from the IRS?

Full answer

For Form 2290, the standard registration document is your IRS-stamped Schedule 1. E-filers get it from their filing provider after acceptance; paper filers receive it by mail. If you need another copy, use your provider’s download, or follow the IRS replacement-request instructions.

For the payment itself, save your EFTPS acknowledgment, card receipt, bank withdrawal record, or canceled check. A receipt showing that a payment was scheduled is different from evidence that it settled, so match the amount, payment date, EIN, and tax period.

When a third party asks for proof, find out whether it needs registration documentation (Schedule 1), a transaction receipt, or an IRS account record — most state DMVs and IRP offices want Schedule 1.
