You may want to think about participation in the IRS' offshore tax amnesty program (called the Offshore Voluntary Disclosure Initiative). Do you want to play audit roulette with the IRS? Some believe that their cases are too small to be prosecuted. They are wrong.
To the average businessperson, only the guys with tens of millions secretly stashed in Swiss bank accounts get prosecuted. Don't tell that to Michael Schiavo. He was just prosecuted for hiding money in a Swiss account back in 2003. How much money does the IRS say he hid? A whopping $90,000. That's it.
But wait, there is more to the story. Schiavo attempted to do a quiet disclosure during the 2009 amnesty but instead of filling out the amnesty paperwork, he simply trusted that by coming forward voluntarily he could avoid criminal prosecution. He was wrong on all counts. Nothing is too small for the IRS, and nothing is too old.
