Every filing season the same question comes up for half your clients: old regime or new? The honest answer is that it depends on their deductions, their income mix, and how much they actually claim versus how much they could.
Here is a simple way to think about it, and a faster way to get the answer.
When the old regime usually wins
The old regime rewards deductions. If your client genuinely uses them, it often comes out ahead.
- They use the full 80C limit: provident fund, ELSS, insurance, school fees.
- They pay home-loan interest and claim it.
- They have a real HRA claim from rent paid.
- They contribute to NPS or claim 80D for health insurance.
When the new regime usually wins
The new regime offers lower slab rates but takes most deductions off the table. It tends to win when there isn't much to deduct.
- Younger clients early in their careers with few investments.
- People who don't pay rent or a home loan.
- Anyone whose deductions don't add up to much in practice.
The catch: you have to compute both
There is no shortcut to being sure. The only way is to work out the numbers under both regimes and compare. Done by hand, that is two computations per client, every year.
This is exactly the kind of repetitive work CA Helper takes off your plate. Upload the documents once, and you get the tax under both regimes side by side, with the cheaper option flagged. You make the call; the maths is already done.
