IRA question

[cardsharkk04]

I've been a caddy for the last 6 years and have never reported taxes (its all untraceable cash). This year I have to report the 50k I made playing poker last year. Is it worth it to report the 5k I made caddying last summer along with the poker winnings, and put it into a roth IRA, or do you think it is better to to not report it, not pay taxes on it, and just invest it myself??

Any feedback is helpful, thanks
