   (c) Effect of determination.

3. (1) Determination by the Division of Taxation of the amount of tax due will finally and irrevocably fix the tax unless the person against whom it is assessed, within 90 days of the date of mailing of the notice of such determination, applies to the Bureau of Conciliation and Mediation Services for a conciliation conference or to the Division of Tax Appeals for a hearing, or unless the Division of Taxation of its own motion redetermines the same.
