Since you never filed a tax return in over fourteen (14) years, the Internal Revenue Service can go back over these Fourteen years and claim unpaid taxes owed by you. Had you filed tax returns for any year with the Internal Revenue Service, the statute of limitations that would apply would be three (3) years as to each filed tax year of your return.Potentially the Internal Revenue Service can go after you for unpaid taxes for tax years prior to 2003. In settling with the Internal Revenue Service for tax years 2004 through 2008, it is important that you try and obtain a full and written release from not only for these years but possibly any other unpaid taxes owed by you.You should have either an attorney who practices tax law or a certified public accountant assisting you in your negotiations with the Internal Revenue Service over back taxes owed.Good luck.
