How do I confirm how I paid my extension amount?

[HelenaC]

Check your bank account or contact your credit card company.

• The IRS does not send confirmation or proof of payment for taxes owed or gives a receipt. You should have a cancelled check, bank or credit card statement showing the payment, depending on how you chose to pay the taxes.
