If you had more then $10k in neteller in 2006 but didn't pay taxes!!

It's very unlikely you will get audited or ever have to pay if you don't speak up. For me, though, it was worth paying anyway to avoid having to worry about it. As you get older, you realize that the lack of worries and concerns is actually worth quite a bit of money.

Although the small dollar amounts you mention make it very unlikely you'll have to think about jail time, you definitely would have to think about it if you did similar things in the future with larger sums. Conscious negligence is much less likely to be forgived then a simple mistake.
