Can I change or switch tax regime?

A salaried person with no business income has the option to choose between the old and new tax regimes every year i.e. he/she can switch regimes from year to year.

However, individuals having business income are not eligible to choose tax regime every year. Once they opt for the new tax regime, they will have only one-time option of switching back to the old tax regime. Once they change it, they will not be allowed to opt for new tax regime again.
