How Section 32 Accelerated Depreciation Works
Under Section 32(1)(ii) of the Income Tax Act, commercial enterprises and manufacturing units that invest in renewable energy assets (specifically solar photovoltaic power plants) are entitled to an Accelerated Depreciation (AD) rate of 40% on a Written Down Value (WDV) basis in the first financial year of commissioning.
If the solar plant is commissioned on or before September 30 of the financial year (>180 days of operation), the full 40% depreciation can be claimed in Year 1.
If commissioned after October 1 (<180 days), 20% is claimed in Year 1, with the remaining balance rolling over to Year 2.
