Saving provisions preserve accrued rights and allow continuation of tax assessments and proceedings as if repeal had not occurred.

Section 174 establishes a comprehensive saving regime: repeal does not revive expired laws, and it preserves prior operation, accrued rights, liabilities, and enforceability of taxes, penalties, interest and related proceedings; investigatory, assessment, refund, recovery and appellate processes may be instituted or continued as if repeal had not occurred, and existing subordinate instruments remain effective insofar as they relate to periods before the appointed day or matters connected thereto.
