Poker Income...Help!

[WangTactics]

I'm new to this forum, but I have a huge question for anyone that can help me out. I play almost exclusively 5cd on Poker Stars, and 99.9% of the time it's PL. The issue I'm running into is this: After quad-tabling for 6 months or so and playing any limit with donks at the table, I've cleared almost $25,000 in profit into my pocket. Now the main question.

I'm basically on pace to make $40,000 to $50,000 in profit this year. Is there any way I can get this money tax free in a legal way??? I do know I am allowed to gift up to $10,000 per child per year, and I have 2 kids, so I believe I'll be able to keep $20,000 of it tax-free...but what about the rest? Am I going to have to pay out taxes to the government on it? I reside in the USA, by the way.
