Section 115BAA against the old rates at your income, with what each regime gives up set out beside the difference.

Old-regime rate

Which old rate applies is decided by turnover two years back — it is not a choice.

On tax alone, Section 115BAA, 22% is the cheaper of the two you can elect.

How this worksShow

The rates are the easy half

Section 115BAA is 22% with a flat 10% surcharge and 4% cess — 25.168% however much the company earns. The old rates carry a surcharge that steps with income, so the gap between the two depends on where the company sits: at eight crore it is worth over sixty lakh a year, and at eighty lakh it is 0.832 of a percentage point.

What 115BAA gives up

This is the half a rate table cannot price, and for some companies it decides the answer. A company sitting on MAT credit loses it outright on electing — which can leave it worse off at 22% than it was at 30%, and the election cannot be undone.

Two things this page will not do

It will not recommend section 115BAB. Closed. Manufacture had to commence on or before 31 March 2024, so no company can elect this now. Shown for a company already in it. A calculator that named it the cheapest would be telling a visitor they can elect something that closed before they read about it — so it is priced, shown, and left out of the comparison.

It will not offer the 25% and 30% rates as alternatives either. Which of them applies is decided by turnover two years back; it is not a choice, and treating it as one would tell a large company it can elect a rate that is not open to it.

  • The comparison is on tax alone. Nothing here weighs a MAT credit, a brought-forward loss attributable to additional depreciation, or an SEZ deduction still running.
  • The election is irrevocable, so it is worth modelling more than one year before making it.
  • MAT stops applying under either concessional regime — which is a saving on one side and a lapsed credit on the other.
