The event was originally planned for an alternative venue in Moscow, but the promoters decided on the switch when they successfully negotiated the use of the Russian seat of power.
A replacement tournament will still be staged in Moscow on the original dates of November 22-23.
"It's awesome. Put it this way, it's the best venue I will have ever played in," said co-promoter John Higgins, who has already qualified for the final.
"It certainly demonstrates what this series is all about, taking the game to different countries throughout Europe."
The World Series is organised by FSTC Sports Management and broadcast throughout Europe on Eurosport. FSTC chief executive Pat Mooney has spoken of his delight at the Kremlin news.
"The chance to hold the final in the Kremlin, one of the world's most iconic buildings, was irresistible. It will be the ultimate launching pad for snooker in Russia," Mooney said
"Eurosport, who have been covering the event, and the World Series of Snooker have had thousands of ticket enquires from fans all over Europe.
"We originally fixed the final for Moscow next month but when a chance came to play it in the Kremlin in March, John and I decided we could not possibly say no.
"However, to avoid disappointment for fans an additional World Series leg will be run on the original dates towards the end of November at another venue in Moscow."
The World Series began this year and events in Jersey, Berlin, and Warsaw have already taken place.
