Your Income Details
Why taxpayers need a reliable income tax calculator
Tax filing is no longer only about submitting an ITR. It is about choosing the right regime, checking deductions, avoiding mismatches, verifying TDS, and reducing the risk of notices.
Old vs new regime confusion
Many taxpayers are unsure whether they should claim deductions under the old regime or use the simplified slab structure of the new regime. A calculator helps compare both paths before filing.
Fear of notices and penalties
Incorrect income reporting, mismatch between Form 16 and AIS, unreported interest income, and late filing may increase the risk of notices, interest, penalties, or refund delays.
Lack of deduction awareness
First-time filers often miss deductions such as 80C, 80D, NPS, HRA, home loan interest, and eligible exemptions under the old regime. Planning early can improve compliance and savings.
Income tax slabs under new regime for FY 2025-26
The new tax regime is the default regime. It offers lower slab rates but restricts many common deductions available under the old regime.
| Taxable Income Range | New Regime Rate | Key Planning Point |
|---|---|---|
| Up to ₹4,00,000 | Nil | No slab tax on this portion. |
| ₹4,00,001 to ₹8,00,000 | 5% | Useful for lower and middle-income taxpayers. |
| ₹8,00,001 to ₹12,00,000 | 10% | Eligible resident individuals may receive Section 87A rebate up to the prescribed limit. |
| ₹12,00,001 to ₹16,00,000 | 15% | Tax starts increasing once income crosses rebate threshold. |
| ₹16,00,001 to ₹20,00,000 | 20% | Compare with old regime if you have large deductions. |
| ₹20,00,001 to ₹24,00,000 | 25% | High-income taxpayers should review deductions, surcharge, and investment planning. |
| Above ₹24,00,000 | 30% | Expert planning is recommended for complex income sources. |
Frequently asked questions on FY 2025-26 income tax calculation
Is the new tax regime mandatory for FY 2025-26?
The new regime is the default regime, but eligible taxpayers can opt for the old regime subject to applicable rules. Salaried individuals without business income can generally choose while filing the return. Business or professional taxpayers may need to follow additional procedural requirements.
Can I claim 80C and 80D deductions in the new tax regime?
Most common deductions such as 80C, 80D, HRA, and LTA are not available under the new tax regime. This is why comparing both regimes is important before filing.
Why does my taxable income differ between old and new regime?
The old regime allows more deductions and exemptions, while the new regime offers simplified lower slab rates with fewer deductions. Your final taxable income changes depending on which deductions are allowed.
Does this calculator handle capital gains and crypto income?
This calculator is designed for regular slab-based income estimation. Special-rate income such as capital gains, crypto, lottery, and online gaming income may require separate tax treatment and expert review.
Can first-time filers use this calculator?
Yes. First-time filers can use it to understand estimated tax liability, basic deductions, rebate impact, regime comparison, and potential tax payable or refund position before filing.
