Block assessment scope expanded to include virtual digital assets; computation, revival and timeline rules updated.

Amendments bring virtual digital asset within the definition of undisclosed income for Chapter XIV-B; add "recomputation", "reference" and "order" to the list of proceedings that may revive if a Chapter XIV-B proceeding is annulled; replace "pending" with assessments "required to be made" for subsequent searches; amend computation rules to recognise undisclosed income declared in return and include returns filed before search or requisition for credit; exclude income from international or specified domestic transactions from block period income; and change the block assessment time limit to twelve months from the end of the quarter of the last authorisation.
