This is not a situation to take lightly, failing to file your tax returns can be a criminal offense.
Let me help you file your returns to be 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.
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.
Before anything can be done to extract you from this predicament all the returns must be filed. You must be current. In most cases, you will likely owe taxes, interest, and penalties after the returns are filed. Once I see how much is owed, I'll set a course of action to resolve the tax, penalties, and interest assessed.
