Every day the massive computer center at the IRS is getting more sophisticated, so if you haven't filed your required returns for years past, it's likely a matter of time before they catch up with you.
This is not a situation to take lightly, failing to file your tax returns is a criminal offense. If you do not file, you can be prosecuted and punished with potential jail time, one year for each year not filed. Why risk potentially losing your freedom for failing to file your tax returns?
Let me give you the peace of mind you deserve by helping you get in compliance with the law. If you voluntarily file your delinquent returns, you'll likely avoid further problems, other than having to pay the interest and penalties. Before anything can be done to extract you from this predicament, all the returns must be filed. You must be current. If you wait for the IRS to file your returns for you, they are filed in the best interest of the government, usually with little or none of the deductions you are entitled to.
