Smart Income Tax Calculator
Compare old vs new tax regimes, calculate income tax instantly, and discover smart tax-saving insights for FY 2024-25.
This calculator compares your income tax liability under India's old and new regimes side by side. Enter your income and deductions, and it applies each regime's slabs to show the tax payable under both — making it clear which one leaves you better off. Slab rates change with each Union Budget, so verify against the current finance act.
How income tax is calculated
Enter your income
Annual salary, bonus, and other income (rental, freelance, interest) sum up to your gross total income.
Claim eligible deductions
Old regime: 80C (1.5L), 80D, home loan, NPS, HRA, education loan. New regime: just the ₹75K standard deduction.
Apply slabs
Progressive rates kick in — 5/20/30% (old) or 5/10/15/20/30% (new). 87A rebate zeros tax up to ₹5L (old) or ₹7L (new) taxable income.
Add cess and surcharge
4% Health & Education Cess on base tax. Surcharge 10-37% if your taxable income exceeds ₹50 lakh.
Best tax-saving tips for salaried Indians
Max out 80C (₹1.5L)
ELSS / PPF / EPF / Tax-saving FDs / Life insurance premiums. Saves up to ₹46,800 if you're in the 30% bracket.
Add NPS for ₹50K extra
Section 80CCD(1B) is over and above 80C — additional ₹50K deduction = up to ₹15,600 tax saving.
Health insurance (80D)
Up to ₹25K for self+family + ₹25-50K for parents. Practical safety net that doubles as a tax deduction.
Use HRA fully
If you live in a rented home, claim HRA exemption — often the largest deduction for salaried folks in metros.
Home loan interest (Sec 24)
₹2L on self-occupied; full interest on let-out property. Combined with 80C principal repayment (within ₹1.5L cap).
Education loan (80E)
Full interest paid on education loans is deductible — no cap. Available for 8 years from start of repayment.
Old vs New Tax Regime — Explained
Old Regime
Higher rates, but a buffet of deductions. Best for people with significant 80C investments, home loans, HRA, and health insurance.
| Income | Rate |
|---|---|
| Up to ₹2,50,000 | 0% |
| ₹2.5L – ₹5L | 5% |
| ₹5L – ₹10L | 20% |
| Above ₹10L | 30% |
New Regime (default)
Lower slab rates but most deductions disabled. Best for people without big tax-saving investments.
| Income | Rate |
|---|---|
| Up to ₹3,00,000 | 0% |
| ₹3L – ₹7L | 5% |
| ₹7L – ₹10L | 10% |
| ₹10L – ₹12L | 15% |
| ₹12L – ₹15L | 20% |
| Above ₹15L | 30% |
Section 80C explained
The most popular deduction in the old regime — combined cap of ₹1,50,000 across: EPF, PPF, ELSS mutual funds, life insurance premiums, NSC, tax-saving FDs (5-year lock-in), tuition fees (up to 2 children), principal repayment on a home loan, and Sukanya Samriddhi. Maxing out 80C saves you ₹46,800 if you're in the 30% bracket (excluding cess).
HRA tax benefits guide
House Rent Allowance is exempt up to the LEAST of: (1) actual HRA received, (2) rent paid minus 10% of basic salary, (3) 50% of basic salary (metro) / 40% (non-metro). You need rent receipts and your landlord's PAN if annual rent exceeds ₹1 lakh. HRA exemption is one of the biggest tax savers for renters in big cities.
Salary tax planning tips
- Start in April, not March. Spreading 80C investments across the year smooths cash flow and lets you average market entry.
- ELSS > tax-saving FDs. 3-year lock-in vs 5-year, equity returns historically beat FD rates.
- Re-evaluate regime every year. Salary hikes, new home loans, or new investments can flip the answer.
- Don't take loans just for deductions. Pay 30% interest to save 30% tax = math doesn't work.
- Watch the surcharge cliff at ₹50L. Just over ₹50L taxable triggers a 10% surcharge — sometimes worth bumping deductions to stay below.
How to decide between the two regimes
The regimes differ in one structural way: the old regime charges higher rates but lets you reduce taxable income through deductions and exemptions; the new regime charges lower rates but removes most of them. Everything else follows from that trade.
So the decision reduces to a single question: do your actual deductions exceed the break-even point? There is an amount of deduction at which both regimes produce identical tax. Claim more than that and the old regime wins; claim less and the new one does. Someone paying a home loan, contributing to provident fund, paying health insurance premiums and claiming house rent allowance can clear that threshold comfortably. Someone renting informally with no loan and no investments usually cannot.
The mistake worth avoiding is counting deductions you do not actually claim. A Section 80C limit is not a deduction until the money is genuinely invested, and house rent allowance requires rent actually paid with proof. Enter the figures you will really put on your return, not the maximums the sections permit.
Because slab rates, rebate thresholds and the standard deduction are revised in almost every Union Budget, this page deliberately does not print them. The calculator applies the current figures; for the authoritative source, check the Income Tax Department before filing.
