Retention Rationale

The Income Tax Regulations, 5800 (1) (a) (iv) states that the retention period for "the general ledger or other book of final entry containing the summaries of the year-to-year transactions of a corporation" is "the period ending on the day that is two years after the day that the corporation is dissolved"; the retention period for sub-ledgers and transaction detail allows access to the information for long enough in most cases to meet the requirements of granting agencies and other sponsors of research.
