Report your winnings like a business.. Pay your taxes..
We all enjoy our street lighting at night, law enforcement when needed, streets paved and sidewalks kept clean. Public schools are nice and free.. Etc..
That's what a portion of your taxes pay for.. Bite the bullet, claim and pay.. BE A TEAM PLAYER!!! You'll feel good about yourself in the end if you think of it that way.
Also - The more taxes you pay every year that just means the more money you made in that year.. That's a good thing celebrate!!! Not a bad thing when you look at it that way..
