Tax
"Do I owe tax this year?" sounds like it should have a quick yes-or-no answer. In practice it depends on which regime you're under, what kinds of income you have, and deductions you may not have fully accounted for.
Start with the basic exemption
Under the new tax regime, the default for FY 2025-26, income up to a set threshold is taxed at nil, and a rebate under Section 87A can bring your effective tax to zero up to a considerably higher income level, provided that income doesn't include specially-taxed items like certain capital gains. Under the old regime, the basic exemption is lower, but you can bring taxable income down further through 80C investments, HRA, and other deductions.
The practical result: two people with identical gross income can have completely different tax outcomes depending on which regime they're under and how they've structured deductions.
The rebate isn't the same as being exempt
This trips people up specifically. Section 87A's rebate reduces your tax liability to zero if your taxable income falls within its limit, but it doesn't mean that income was never taxable in the first place, and it doesn't remove your obligation to file if your gross income (before deductions) crosses the filing threshold. You can legitimately owe zero tax and still be required to file a return.
Income types that change the answer
Salary income is the most straightforward to estimate; TDS is usually already deducted with your regime in mind. But other income types shift the picture:
- Capital gains from equity or mutual funds are taxed at specific rates that don't always follow the regular slab structure, and short-term gains are treated differently from long-term ones.
- Interest income from savings accounts, fixed deposits, and bonds is added to your total income and taxed at your slab rate, though a limited deduction exists for savings account interest under the old regime.
- Freelance or business income is taxed after allowable expenses are deducted, and depending on turnover, you may qualify for presumptive taxation, which simplifies the calculation considerably.
A rough way to check
- Add up gross income from every source for the financial year.
- Under the old regime, subtract deductions you actually have proof for, not ones you're planning to make before the deadline.
- Compare what's left against the applicable slab rates for your chosen regime.
- If tax comes out to a small number, check whether Section 87A's rebate brings it to zero.
- Separately, run the same income through the other regime to see if it produces a better result. Doing this once, properly, before deciding which regime to file under is worth more than most tax-saving purchases people make in a hurry.
If any of this feels uncertain, especially with multiple income types or capital gains involved, a proper computation through a filing platform or a tax professional is worth the small cost. Getting it wrong doesn't just mean an inaccurate estimate, it can mean an incorrect return.
