The 30-year-old left-back has signed on the dotted line with the newly promoted club.
The former Leeds United star, who spent seven years at Burnley, has gone far down south to the Saints for his next move.
"It just feels the right fit," he shared with club media.
“Everyone I spoke to about the club have only got great words to say. I'm so excited and can't wait to get started.
"Ever since I've come down here, I've just had a good feel, good people. It's a huge club, back in the Premier League, and just a good experience for me."
"The Premier League is probably the best league in the world, it's such a tough league with outstanding quality every week so I know how hard it is to be in that league and to stay up." Taylor added.
"I fully believe that we can (survive) this year with the squad and the management that we've got here.
"I spoke on the phone briefly to begin with (Russell Martin) and straight away he really impressed me, just the way he talks about football is the way I like to see it as well.
"The people I spoke to who know him as well only had good things to say, and I think him being the manager was a massive pulling point as well.
"There's no reason at all why this club can't stay up and progress even more."
