Which Tax regime (New or Old) is beneficial with different income slabs, please explain.
Ans: The tax slabs themselves are very broad and your benefits depend on what sections of Income Tax Act are you taking benefit of like 80C, 80G, 80D, 80E, 24B, and HRA.
Instead of looking at broad tax slabs, please calculate yourself at this calculator as pertaining to yourself and you will be able to decide which tax regime is better for you:-
