And he 31-year-old, capped 49 times, will now end his career at Edgeley Park despite interest from Bristol, London Irish and Cardiff Blues.
"At the end of the day it was a rugby decision. I was offered more money elsewhere but the chance to play alongside the likes of Jason Robinson, Charlie Hodgson and Mark Cueto was a the real attraction at Sale," said Taylor. "It will be a big wrench to leave Wales having played all my rugby here but if I've always fancied a new challenge and this is the ideal time."
Taylor only played a handful of games for Llanelli this season after being struck down by an eye infection before making a surprise comeback on the wing for Wales in the game against Ireland that clinched the Grand Slam last month.
He said: "It has been a strange season, frustrating but memorable. All I want to do now is get regular rugby. The Zurich Premiership is up with France as the most competitive league in Europe."
