We all know that the rich have a zillion strategies and loopholes to avoid paying their share of taxes (Iris Lilies and Alan are probably now triggered).

But what about for the workin' man (perhaps this workin' man)? Are there any strategies for a lowly gubmint employee to legally pay significantly less in taxes?

I remember hearing that contributing a certain amount to a Roth IRA can make it like you earn less money and therefore possibly pay less tax. Is this true?
Are there any other ideas people have?

Thanks!
