If you’re wondering whether the IRS received your payment, here’s how to find out:
1) If you made your payment by phone or online through the Electronic Federal Tax Payment System (like many businesses and self-employed do), you can check your payment status by accessing your EFTPS account at EFTPS.gov.
2) If you made your payment by another method, call the IRS. They can help you check on the status of your payment, or help you locate a missing payment. Just call the toll-free number shown on the top of the notice or bill from the IRS.
