Does anyone have IRS address? I am overseas filing a 1040. FedEx told me that Department of Treasury Internal Revenue Service Austin TX xxxxx-xxxx USA is not valid.

Per the IRS Website: International Filing Addresses for Form 1040.

If you are filing without a payment, use this address:

Department of the  Treasury
Internal Revenue Service
Austin, TX  73301-0215
USA

If you are filing with a payment, use this address:

Internal Revenue Service
P.O. Box 1303
Charlotte, NC 28201-1303
USA

NOTE: *If you live in American Samoa, Puerto Rico, Guam, the U.S. Virgin Islands, or the Northern Mariana Islands, see Pub 570.
