WASHINGTON — Representative Dave Camp, the Michigan Republican who is the chairman of the House Ways and Means Committee, announced Monday that he would not run for re-election.

“This decision was reached after much consideration and discussion with my family,” Mr. Camp, 60, said in a statement.

“Serving in Congress is the great honor of my professional life,” he said. “I am deeply grateful to the people of the Fourth Congressional District for placing their trust in me. Over the years, their unwavering support has been a source of strength, purpose and inspiration.”

The retirement of Mr. Camp, who was first elected to Congress in 1990 — the same class as the House speaker, John A. Boehner of Ohio — did not come as a surprise to many on Capitol Hill. His six-year term as the top Republican on the tax-writing committee ends this year, leaving an opening for Representative Paul D. Ryan of Wisconsin, the Republican Party’s 2012 vice-presidential nominee, to replace him.
