Phil Mickelson said “drastic changes” are ahead for him because of increases in the federal and California tax rates.

“It’s been an interesting offseason,” Mickelson said Sunday after finishing in a tie for 37th in the Humana Challenge. “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, who lives just outside his hometown of San Diego, said he would divulge details before the Farmers Insurance Open starts Thursday at Torrey Pines in La Jolla.

“I’m not sure what exactly, you know, I’m going to do yet,” Mickelson said. “I’ll probably talk about it more in depth [then]. I’m not going to jump the gun, but there are going to be some [changes]. 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.”

Mickelson might be contemplating a move to Canada or Florida or becoming Prince Phil of Monaco or even, gasp, semi-retirement at 42. “You know, I think that we’re all going to have our own way of handling things, handling time in our career, our family, handling what’s going on the last couple of months politically. I think we’re all going to have to find things that work for us.”

Mickelson has more than $67 million in career earnings and was the seventh highest-paid athlete on Forbes’s 2012 list with $47.8 million in earnings (including $43 million in endorsements).

Late last year, Mickelson pulled out of a group that was purchasing the San Diego Padres and he said the move “absolutely” was related to the coming changes in tax rates for the wealthy. He’ll be pressed for details this week at Torrey Pines.

“I’ll probably be a little more open to it because San Diego is where I live, it’s where the Padre thing was a possibility and it’s where my family is.”
