Key points

1. Extra-judicial settlement. The Regulations also give the rules for settling a taxpayer’s criminal violation of the Code or its Regulations outside of court, through payment of a suggested compromise penalty.
2. Interest on partial or installment payments. When tax is paid partially or in installments, interest on the deficiency or delinquency tax runs from the due date until full payment. It is computed on the diminishing balance of the tax, inclusive of interests.
