The 'Shake It Off' hitmaker's haul over the last year largely came from her '1989' world tour, which smashed the North American touring record of the Rolling Stones to pull in $250 million, and her fortune was boosted with appearances in commercials for the likes of Apple, Diet Coke and Keds.
Entertainment attorney Lori Landew told Forbes magazine: "She has been building her fan base for years, and that fan base crosses multiple market segments.
"It's this ability to appeal to younger and older audiences, and those in between, that makes Taylor such a sure bet with both concert promoters and brands who want to affiliate with her and with the community she has cultivated."
The 26-year-old singer's fortune was more than double that of second-placed Adele, whose ranking on Forbes' annual list came with earnings of $80.5 million thanks to astonishing sales of her third album '25'.
Pop veteran Madonna took third place on the list with $76.5 million. Like Taylor, much of her revenue came from performing live, with her 'Rebel Heart' world tour grossing $170 million.
Rihanna was narrowly behind in fourth place with $75 million, and Beyonce's $54 million saw her take fifth position.
Katy Perry - who took the top slot last year - was placed sixth with $41 million, just ahead of Jennifer Lopez with $39.5 million.
Britney Spears, Shania Twain and Celine Dion rounded out the top 10.
Lady Gaga, Mariah Carey, Miranda Lambert and Fleetwood Mac's Stevie Nicks and Christine McVie all made the top 10 in 2015 but dropped out this year.
