Since the new tax regime became the default, every taxpayer has to decide each year whether to stay in it or opt for the old regime. The new regime has lower slab rates but disallows most deductions; the old regime keeps deductions like 80C, 80D and HRA.
This guide compares the two so you can pick the one that leaves you with more.
What is New vs Old Tax Regime?
The new regime offers wider, lower slabs and a higher standard deduction for salaried taxpayers, but removes most exemptions and deductions. The old regime has higher slabs but lets you reduce taxable income through investments and expenses.
The right choice depends on how much you can claim in deductions — a high-deduction taxpayer often does better in the old regime; someone with few deductions usually benefits from the new one.
| New regime | Lower slab rates, standard deduction, few other deductions |
|---|---|
| Old regime | Higher slabs but 80C, 80D, HRA, home loan interest and more |
| Default | New regime (opt out for old) |
| Retained in new regime | Employer NPS 80CCD(2), standard deduction |
Step-by-step process
- Total your deductions. Add up 80C, 80D, HRA, home loan interest and other old-regime deductions you can actually claim.
- Compute tax both ways. Calculate tax under both regimes for your income.
- Compare and choose. Pick the regime with the lower tax. Salaried taxpayers can switch each year; business income has more restrictions.
Frequently asked questions
Can I switch regimes every year?
Salaried taxpayers without business income can choose afresh each year. Those with business/professional income can switch back to the new regime only once after opting out.
Which regime is better for me?
If your eligible deductions are high (large 80C, HRA, home loan interest), the old regime may win; with few deductions, the new regime usually saves more.
