The 73-year-old singer, known for such hits as "Proud Mary", "Ooh Poo Pah Doo" and "What's Love Got to Do with It", signed the forms to voluntarily relinquish her citizenship Oct 24, The Washington Post reported, citing a document from the US Embassy in Bern.
Turner affirmed in the documents that she does not have strong ties to the US, "except for family, and has no plans to reside in the US in the future," the daily said.
Turner, who was born in Nutbush, Tennessee, Nov 26, 1939, has lived in Switzerland for more than two decades and married her long-time boyfriend, German producer Erwin Bach, in July.
Turner, who has won eight Grammys and sold more than 100 million records in her career, became a Swiss citizen April 10.
