23 August 2022 I have submitted a nill return for AY 21-22 u/s 139(1) to avoid late fee u/s 234F. Later i have submitted a revised return opting for new tax regime and offered a income of Rs.14 lakh and tax was paid accordingly, while i was uploading my revised return there was no error message. But the return is processed now and i have received order u/s 143(1) mentioning a demand, after analyzing the order i came to know that tax was calculated in old regime. But in case of AY 2022-23, portal shows an error that "New tax regime cannot be opted after the due date", Is there any solution to reduce the demand for the AY 2021-22?
