Pro rata deduction apportionment on co operative bank business reorganisation enables time proportionate tax deductions for successor entities. When a co operative bank undergoes business reorganisation by amalgamation, demerger or conversion within a financial year, deductions under sections 32, 35D, 35DD and 35DDA are apportioned between predecessor and successor (or converted banking company) by applying the full year deduction to the ratio of days before or after the date of reorganisation to the total days in the year. Where an undertaking carrying entitlement under sections 35D/35DD/35DDA is transferred before the expiry of the specified period, those deduction provisions apply to the successor/converted entity in subsequent years as if reorganisation had not occurred.
