If you planned your taxes according to the new tax regime but missed filing your income tax returns (ITR) before the July 31, 2022 deadline, then there is some bad news. As per current income tax laws, you cannot claim the benefit of the new tax regime while filing belated ITR. Not only, you will have to pay taxes according to the old tax regime while filing belated ITR, but there may be chances of a higher income tax liability as well.

What income tax laws say about filing ITR with new income tax regime
Once the deadline to file ITR is missed, then the individual can file a belated ITR using only the old income tax regime. The Finance Bill, 2020, introduced the new income tax regime and it came into effect from FY 2020-21 (April 1, 2020). The Finance Bill makes it clear that in order to avail benefits under the new regime, an individual has to file their ITR within the due date (usually July 31 unless extended by the government) under Section 139(1) of the Income-tax Act,1961. If the income tax returns are filed belatedly, the taxpayer will not be able to claim the benefit of the lower tax rates, as provided for in the new tax regime and the existing, old income tax rates would apply.
