Professional golfer Phil Mickelson announced on Sunday that he plans to make "drastic changes" in the near future because of the rise in federal and California state taxes.

"It's been an interesting offseason," the 42-year-old golfer said after the final round of the Humana Challenge in La Quinta, Calif., as reported by Forbes. "And I'm going to have to make some drastic changes. I'm not going to jump the gun and do it right away, but I will be making some drastic changes."

Mickelson, a native of Rancho Santa Fe, alluded to possibly retiring from playing the game professionally or moving out of California.

"I'm not sure what exactly, you know, I'm going to do yet. I'll probably talk about it more in depth next week," Mickelson said, as he offered more details before the Farmers Insurance Open in San Diego beginning on Thursday at Torrey Pines.

"I'm not going to jump the gun, but there are going to be some. There are going to be some drastic changes for me because I happen to be in that zone that has been targeted both federally and by the state and, you know, it doesn't work for me right now. So I'm going to have to make some changes."

In November, California voters approved Proposition 30, the first statewide tax increase since 2004.

"If you add up all the federal and you look at the disability and the unemployment and the Social Security and the state, my tax rate's 62, 63 percent," Mickelson said. "So I've got to make some decisions on what I'm going to do."

Mickelson closed with a 66 on Sunday to tie for 37th at 17 under in his season debut, according to Fox Sports.

"I was rusty starting the year," Mickelson said. "I had a great four days here where I can work on my game with perfect weather and wonderful golf courses, where I could build some momentum. Heading into San Diego, I feel a lot more confident."
