New vs old income tax regime: how to actually decide

Every year, the same question arrives: new regime or old? The honest answer is that there is no universal winner — it depends on your specific deductions. But the decision is more straightforward than it is usually made to sound.

The core trade-off

The new regime offers lower headline rates but largely removes the familiar deductions and exemptions. The old regime keeps those deductions but at higher rates. So the question is simple to state: do your deductions save you more than the new regime's lower rates would?

When the old regime tends to win

If you genuinely use the major deductions — significant investments, home-loan interest, insurance, and other claims — the old regime often comes out ahead. The more you legitimately deduct, the stronger its case.

When the new regime tends to win

If your deductions are modest — you rent rather than own, you don't have large eligible investments — the new regime's lower rates frequently leave you better off, with far less paperwork.

How to decide properly

Don't decide on instinct. The right approach is to compute your tax both ways using your actual numbers for the year, and pick the lower result. A small calculation removes the guesswork entirely — and the answer can change year to year as your circumstances change.

A planning point

The regime choice interacts with how you structure investments and salary. Deciding early in the year, rather than in March, lets you actually plan around the choice instead of merely reacting to it.
