My mom has received her pension arrears in Oct 2021 -- which spread across 11 years. She retired in 2009 and till 2020 she was getting less pension and then 2021 she started getting her revised pension followed by arrears in Oct of 2021.
I aware of Form 10 E-Option but how do l fill the details for the past 11 years? Finally since no amount has been deducted by pension department is it that the amount is not taxable considering the span of years.
