Explained in this library

What section 72 does, in plain English, before you read what the courts made of it.

s.115BBE: the rate timeline, and why the two limbs of sub-section (2) start on different dates

The officer has taxed my addition at 60% and refused to let me set my losses against it. Was that rate even in force for my year, and from when does the bar on set-off actually run?

s.79: the 51 per cent test, and what a funding round does to the losses

Our closely held company's shareholders have changed. Do the brought-forward losses survive?

Setting off and carrying forward losses

I made a loss this year. What can I set it against, and how long can I carry the rest forward?

Unabsorbed depreciation is not a loss, and that is the whole point

My depreciation could not be absorbed this year. How long can I carry it, and does a late return kill it the way it kills a business loss?

Which Act governs your year: the 1961 Act after 1 April 2026

I am holding a notice and I do not know whether my year is under the Income-tax Act, 1961 or the Income-tax Act, 2025. Which Act applies to me, and is the old Act still of any use now that it has been repealed?
