The IRS is changing the addresses to be used to file estate and gift tax returns, as documented in the instructions for Form 706 and Form 709.

The change in filing estate tax returns (Form 706)will take place for returns filed after June 30, 2019. As of that date, returns filed via the US Postal Service will be sent to:

Department of the Treasury
Internal Revenue Service Center
Kansas City, MO 64999

Forms 706 filed via an approved private delivery service will be sent to:

Internal Revenue Service
333 W. Pershing Road
Kansas City, MO 64108

For returns filed prior to that date, the addresses in Ohio (for USPS delivery) and Kentucky (for PDS delivery) will continue to be used.

The same addresses will be used to file Form 709 for gift tax returns, but returns filed on or after January 1, 2019 are to be sent to the Missouri addresses.
