They never actually became true allies. Russia never declared the U.S. as an ally, only Great Britain and France. But after the events at Pearl Harbour (7th December 1941) the U.S. joined the war on the British side. Russia even started of against Britain, signing a 'no-contact' agreement with Hitler. But after Hitler invaded Russia (June 22nd 1941) Russia joined back with Britain. So the answer to your question would be 7th December 1941, but it was never official.
