You may not have filed because you owe additional tax that you cannot afford to pay in full. You may not have filed because you expect a refund and just have not taken the time to complete the return.
Regardless of your reason for not filing, you should file your tax return as soon as possible. If you cannot pay all of the tax due on your return, you may be able to arrange payments, an Offer in Compromise, or "Currently Not Collectible" status, depending on your situation.
