Executor's right of recovery: statutory mechanism to reclaim taxes paid from the estate, subject to procedural adaptations.
Clause 312(7) makes Section 305 applicable to executors "so far as may be" in respect of tax paid or payable by them, treating executors as representative assessees and thereby enabling statutory recovery of taxes from the estate or beneficiaries while permitting necessary adaptations of procedures and raising questions on priority and apportionment in insolvent or contested estates.

Taxation of deceased estates: executor liable for estate income until complete distribution, with legatee inclusion on distributed income.
Clause 312 taxes income of a deceased person's estate in the hands of the executor or administrator, with a single executor assessed as an individual and multiple executors as an association of persons; the executor is deemed to have the deceased's residential status for the tax year of death, assessments of estate income are separate from the executor's personal returns, separate assessments apply for each tax year or part thereof until complete distribution, and income distributed to specific legatees is excluded from the estate's income and included in the legatees' income.
