The 'Blank Space' singer is nominated for three awards at the Los Angeles music ceremony but this year she'll be staying in the audience rather than belting out one of her famous hits.
Taylor told fans she was "really excited" to be a multiple nominee, adding: "And I'm even more excited that I'll be there having a dance party / rage fest in the audience!"
"Since my whole life is wrapped up and entangled in the planning of The 1989 World Tour right now, I'm not going to be performing on the Grammys this year. I need this time to focus only on the tour.
"I hope I'll see you out there at one of the stadiums this summer having a rage fest of your own!"
Fans will see Taylor on stage, however, as she's lined up to present the 'Best New Artist' award. Iggy Azalea, Bastille, Brandy Clark, Haim and Sam Smith are nominated.
How cool if Haim won! Taylor's just signed them up to support her on a string of dates on her world tour.
Taylor's received three major nominations at this year's awards: 'Song of the Year' and 'Record of the Year' for 'Shake It Up' and 'Best Pop Solo Performance'.
The Grammys take place Sunday, 8 February.
