As Al Capone and other gangsters have learned over the years, murder and other violent crimes take a back seat to what is considered the most heinous offense that can be perpetrated against our society – tax evasion.
It is also an ironic fact that most of the tax scofflaws, such as some reformed tax protestors and delinquents with whom I have worked, end up owning much less in taxes when they voluntarily file their professionally prepared returns than by letting the IRS and State tax agencies do the calculations based on the one-sided information they have for non-filers. In many cases, there have even been overpayments that had to be forfeited because of the statute of limitations on claiming refunds.
