Income tax expense (benefit) as at March 31, 2021 was recorded (i) in retained earnings for the tax effect of ASU 2016-13 for current expected credit losses (CECL) Rs. (21,016.0) million, (ii) in other comprehensive income Rs. (8,457.8) million.
Income before income tax expense and income tax expense are substantially all from India.
On December 12, 2019, the India Taxation Laws (Amendment) Act, 2019, was promulgated, which provided domestic companies with an option to pay income tax at the rate of 22 percent (previously 30 percent), provided they do not claim certain deductions under the Income Tax Act with effect from the financial year
2019-20
.
The bank elected to be subject to the 22 percent rate (25.17% including surcharge and education cess).The Bank has accounted for the effect of this change in the income tax rate
during the year ended March 31, 2020
 
using reasonable estimates based on information
available at the time
and its interpretations
 
of the
law thereof, effective from financial year 2019-20.

Management believes that the realization of the recognized deferred tax assets is more likely than not and the realization is based on a combination of reversing taxable temporary differences and expectations as to future pretax income.
The total unrecognized tax benefit as of March 31, 2020 and March 31, 2021 is Rs. 37,103.2 million and Rs. 43,048.0 million, respectively. The major income tax jurisdiction for the Bank is India. The open tax years (first assessment by the tax authorities) is pending from fiscal 2019 onwards. However, appeals filed by the Bank are pending with various local tax authorities in India for earlier tax years.
A reconciliation of the beginning and ending balance of unrecognized tax benefits is as follows:

The Bank’s total unrecognized tax benefits, if recognized, would reduce the income tax expense by Rs.
 
37,103.2 million and Rs.
 43,048.0 
million as of March 31, 2020 and March 31, 2021, respectively, and thereby would affect the Bank’s effective tax rate. Unrecognized tax benefits are unrecognized refund claims.
Significant changes in the amount of unrecognized tax benefits within the next 12 months cannot be reasonably estimated as the changes would depend upon the progress of tax examinations with various tax authorities.
