John T. Rogers, 69, a lawyer with the Internal Revenue Service and its predecessor agency for more than 30 years, died of cancer Friday at Georgetown University Hospital.

He worked for Internal Revenue in Newark, N.J. Birmingham, Ala., and Philadelphia, before returning here as director of the tax court litigation division in the chief counsel's office. From 1971 until retiring two years later, he was an associate chief counsel of litigation in the chief counsel's office, one of the highest career posts in Internal Revenue.

He won a number of government awards, including the Treasury Department's Exceptional Service Award in 1973.

Mr. Rogers was a native of Creedmoor, N.C. He earned bachelor's and law degrees at the University of Florida. He was chairman of the honor court at school. He practiced law in North Carolina before coming here.

A member of the North Carolina and Florida bars, he was admitted to practice law before the U.S. Supreme Court.

He belonged to the North Carolina Society, the Sons of the American Revolution, and the North Carolina Democratic Club.

Mr. Rogers was a member of Temple Hills Baptist Church. He belonged to the Barrister's Lodge of the Masons here.

He is survived by his wife, the former Henrietta Davis, and a son, John Jr., both of the home in Bethesda; two daughters, Deanna Breck, of Yuma, Ariz, and Susan Angle, of Burke, Va.; a sister, Dr. Carmen Rogers, of Tallahassee, Fla; 10 granchildren, and one great-grandchild.
