The Bad Blood singer raked in $317.8 million since January thanks to her 1989 album and world tour and endorsement deals, according to the Sunday Express.
This makes Taylor the highest earning musician in the world.
LA-based media analyst Mike Raia said: "Right now, Taylor is untouchable.
"She is so far ahead of everyone else in the industry that she has become not only a powerhouse entertainer but also an important mover and shaker on the commercial side of the music business."
This comes after Taylor and her boyfriend Calvin Harris were recently named the world's highest-paid celebrity couple.
The 25-year-old singer-songwriter and the British DJ's respective endorsement deals helped them to replace Jay Z and Beyoncé at the top of Forbes magazine's annual list.
Taylor - who started dating her new beau in February - has endorsement deals with the likes of Sony and Keds, while Calvin, 31, has contracts with Giorgio Armani and Sol Republic.
You go Tay-Tay!
