As a senior citizen, my father's pension was within the taxable limit for the past 3 years so he didn't file any tax returns.
Now he wants to spread over the pension arrears he received in 2009 to the past 3 years to minimize his tax liability on arrears.Obviously in which case his income for previous 3 years would go beyond the senior citizen limit.
Since he is also disabled for the past 4 years, can he avail of the deduction under Sec. 80U & 80DDB for the past 3 years corresponding to those years tax liability ?
