If you set up the payment date when you filed your return, you can cancel the transaction up to 48 hours before the scheduled date. If you do that, when you are ready to pay, then you would need to either send in a check for your payment or go to the IRS website to make a payment.
To verify the date that Federal funds will be withdrawn from
your account, confirm that funds have been transferred, or cancel the

debited, call the IRS at 1 (888) 353-4537.
If you set up an installment plan, you need to contact the IRS to change the scheduled date.
