It is not a very common question but you may have wondered which mail carriers that IRS accepts mail from. The IRS has designated three Private Delivery Services that it will accept mail and packages from. This means that if you try and send a tax return or payment for a tax return to the IRS by a carrier that is not designated, they will not accept it.
It becomes even more specific with the actual services that the IRS will accept from each carrier. Not all services from all three carriers will be accepted.
Accepted Carriers & Services
Here is a list of the specific services for each carrier that the IRS will accept:
1. United Parcel Service – UPS Next Day Air, UPS Next Day Air Saver, UPS 2nd Day Air, UPS 2nd Day Air A.M., UPS Worldwide Express Plus, and UPS Worldwide Express
2. Federal Express – FedEx Standard Overnight, FedEx Priority Overnight, FedEx 2Day, FedEx International Priority, and FedEx International First
3. DHL Express – DHL Same Day Service
If you were to choose a different carrier from the list above, the IRS would simply not accept your document or payment. If you were to choose a different service from the carriers listed above and ship it to the IRS, they would simply not accept it even though it is from one of their designated carriers.
Private Deliver Service Postmark Date
A postmark date by a private deliver service is important to the IRS because it determines when that document was actually mailed to them. If you were the mail your document using DHL or UPS, the postmark date would be the exact time your document was electronically recorded into their database. If you were to use FedEx, the postmark date would be the exact time printed on the label created by the FedEx employee.
