Income Tax Calculator 2026
Compare your tax liability under the old and new regime for FY 2025-26 (AY 2026-27). Enter your income and deductions to see which regime saves you more. Updated with latest Budget 2025 slab rates and ₹75,000 standard deduction.
💡Key change for FY 2025-26
Under the new regime, income up to ₹12 lakh is effectively tax-free (via Section 87A rebate). Standard deduction is ₹75,000. New regime is the default — you must actively choose old regime if you want deductions like 80C, HRA, and NPS.
📊New regime vs old regime — slab rates compared
The new tax regime (default from FY 2024-25) has more slabs with lower rates but allows almost no deductions. The old regime has fewer slabs with higher rates but allows deductions under 80C, 80D, HRA, NPS, home loan interest, and more. Your optimal choice depends entirely on how many deductions you can claim.
FY 2025-26 tax slab comparison
🧮Worked example — ₹15 lakh income
New regime: Gross income ₹15,00,000 - ₹75,000 standard deduction = ₹14,25,000 taxable. Tax: 0-4L = ₹0, 4-8L = ₹20,000, 8-12L = ₹40,000, 12-14.25L = ₹33,750. Total = ₹93,750 + 4% cess = ₹97,500.
Old regime (with deductions): Gross ₹15L - ₹50K std deduction - ₹1.5L (80C) - ₹50K (NPS 80CCD1B) - ₹25K (80D) - ₹2L (HRA exempt) = ₹10,75,000 taxable. Tax: 0-2.5L = ₹0, 2.5-5L = ₹12,500, 5-10L = ₹1,00,000, 10-10.75L = ₹22,500. Total = ₹1,35,000 + cess = ₹1,40,400.
Verdict: New regime wins by ₹42,900 in this case. But if this person had ₹3L HRA exemption instead of ₹2L, old regime would win. The breakeven depends on your exact deduction mix. Use the calculator above with your real numbers.
Rule of thumb: if your total deductions exceed ₹3.75 lakh, the old regime likely saves more. Below ₹2.5 lakh deductions, new regime wins. In between — calculate both.
💰Key deductions under the old regime
Section 80C (₹1.5 lakh): EPF contribution, PPF, ELSS mutual funds, life insurance premium, children's tuition fees, home loan principal, Sukanya Samriddhi, NSC, 5-year FD. This is the most used deduction — almost every salaried employee maxes it through EPF alone.
Section 80CCD(1B) (₹50,000): Additional NPS contribution — over and above 80C. This is exclusive to NPS and one of the strongest reasons to invest in NPS even if you're in the old regime. At 30% tax bracket, this saves ₹15,600/year.
Section 80D (₹25,000-₹1 lakh): Health insurance premium. ₹25,000 for self + family. Additional ₹25,000 for parents (₹50,000 if parents are senior citizens). Maximum: ₹1 lakh if both self and parents are seniors. Preventive health check-up of ₹5,000 is included within this limit.
Section 24(b) (₹2 lakh): Home loan interest. Up to ₹2 lakh per year for self-occupied property. No limit for let-out property (but rental income is taxable). For under-construction property, total pre-construction interest is deductible in 5 equal installments starting from the year of completion.
HRA exemption (no cap): Section 10(13A) — minimum of actual HRA, 50%/40% of basic (metro/non-metro), and rent minus 10% of basic. Can be the single largest deduction for employees paying high rent in metro cities. Use our HRA Calculator to compute your exact exemption.
⚠️Common filing mistake
Many taxpayers forget to report interest income from savings accounts, FDs, and RDs. Banks don't always deduct TDS on interest below ₹40,000 (₹50,000 for seniors), but it's still taxable. Not reporting this can trigger a notice during assessment. Check your Form 26AS and AIS (Annual Information Statement) before filing to ensure all income sources are covered.
📅Tax planning timeline for salaried employees
April-May: Start of FY. Begin SIP in ELSS for 80C. Set up NPS auto-debit for 80CCD(1B). Renew health insurance for 80D. Don't wait until March — spreading investments through the year avoids panic decisions.
January-February: Tax declaration window at most companies. Submit rent receipts, home loan certificate, insurance premiums, and investment proofs. This is when your employer adjusts TDS — missing this window means excess tax deducted and waiting for ITR refund.
March: Last month to complete 80C investments for the current FY. If short on 80C, PPF and tax-saving FD allow lumpsum deposits. Don't invest in ULIP or endowment plans just for tax saving — ELSS gives better returns with shorter lock-in.
April-July (next FY): File ITR by July 31. Collect Form 16 from employer (issued by June 15). Verify TDS in Form 26AS matches Form 16. E-verify ITR within 30 days of filing. If claiming refund, track status on incometax.gov.in.
Maximum possible tax savings under old regime
🎯Quick decision framework
Salary under ₹10L: New regime is almost always better (87A rebate makes most income tax-free). ₹10-15L with few deductions: New regime likely wins. ₹10-15L with home loan + HRA + full 80C: Old regime likely wins. Above ₹15L: Calculate both — the answer depends heavily on your specific deduction mix. Use the calculator above with your actual numbers.

🏠Home loan tax benefits — comprehensive guide
Section 24(b) — Interest deduction: Up to ₹2 lakh/year on home loan interest for self-occupied property. No limit for let-out (rented) property, but net rental income loss that can be set off against salary is capped at ₹2 lakh. For second homes, notional rent must be declared even if the property is vacant.
Section 80C — Principal repayment: Home loan EMI has two components: principal and interest. Principal repayment qualifies under 80C (₹1.5 lakh limit shared with EPF, PPF, ELSS). If EPF already uses most of your 80C, the home loan principal gives limited additional benefit.
Section 80EEA — First-time buyers: Additional ₹1.5 lakh interest deduction for first-time homebuyers if stamp duty value doesn't exceed ₹45 lakh and loan was sanctioned between April 2019 and March 2022. This is over and above the Section 24(b) limit. Check if your loan qualifies — this benefit expired for new loans but remains valid for eligible existing loans.
Combined strategy — own + rent: Own a house via home loan in one city (claim ₹2L interest + ₹1.5L principal) while renting in your work city (claim HRA exemption). This is one of the most powerful legal tax optimization strategies for employees posted in different cities from where they own property.
📱ITR filing — which form to use
ITR-1 (Sahaj): For salaried individuals with income up to ₹50 lakh from salary, one house property, other sources (interest), and agricultural income up to ₹5,000. This is the simplest form and applies to most salaried employees. Cannot be used if you have capital gains, foreign assets, or income from business/profession.
ITR-2: For individuals and HUFs with income from salary, house property, capital gains, other sources, and foreign income/assets. Use this if you have stock market gains (LTCG/STCG), ESOPs, or foreign assets. Most employees with Demat accounts and mutual fund investments need ITR-2.
ITR-3: For individuals with income from business or profession (including freelancers). If you have both salary and freelance income, use ITR-3. This form is more complex and may require maintaining books of accounts (unless you use presumptive taxation under 44ADA).
ITR-4 (Sugam): For presumptive income under Sections 44AD (business, turnover up to ₹3 crore) or 44ADA (professionals, receipts up to ₹75 lakh). Simplest form for small business owners and professionals — declare 8% (digital) or 6% (cash) of turnover as profit, no need for detailed books.
⚡Tax-saving strategies for high-income earners
For ₹20-30 lakh income: In the old regime, max out 80C (₹1.5L), NPS 80CCD1B (₹50K), 80D (₹50K with parents), home loan interest (₹2L), and HRA (variable). Total deductions can reach ₹5-6L, saving ₹1.5-1.8L in tax. Compare this with new regime — at ₹25L income, new regime tax is approximately ₹3.9L while old regime with ₹5.5L deductions would be approximately ₹3.5L. Old regime wins for this profile.
For ₹50+ lakh income: Surcharge kicks in at ₹50L (10% on tax). Capital gains planning becomes critical — harvest ₹1.25L LTCG every year tax-free. Consider HUF creation for splitting income. International relocation to NRI status can restructure tax liability. At this level, a CA's fee (₹10-25K/year) pays for itself many times over in tax optimization.
For freelancers earning ₹15-50 lakh: Use Section 44ADA (presumptive taxation) if receipts are under ₹75L — declare 50% as profit, pay tax only on that. Claim business expenses: laptop, internet, co-working, travel, software, courses. Consider forming an LLP above ₹50L turnover for the 30% flat corporate rate instead of personal slab rates (which go to 30% + surcharge).
🔍New vs old regime — the decision framework
Income under ₹12 lakh: New regime wins decisively. Section 87A rebate makes income up to ₹12 lakh effectively tax-free under new regime. Old regime only offers tax-free up to ₹7 lakh after deductions. Unless you have ₹5+ lakh in deductions (unlikely at this income level), new regime saves more. Don't overthink — choose new regime.
Income ₹12-18 lakh with home loan: Old regime likely wins. A home loan gives ₹2L interest deduction (24b) + ₹1.5L principal (80C). Add ₹50K NPS, ₹25K health insurance, ₹50K standard deduction, and ₹1-2L HRA exemption. Total deductions: ₹5-6 lakh. At ₹15L income, old regime tax with these deductions ≈ ₹1.1L. New regime tax ≈ ₹1.5L. Old regime saves ₹40,000.
Income ₹18-30 lakh without home loan: Closer call. Without home loan interest (₹2L deduction), total deductions drop to ₹3-3.5L. At ₹25L income, new regime tax ≈ ₹3.9L. Old regime with ₹3.5L deductions ≈ ₹3.8L. The difference is marginal — new regime wins on simplicity even if old saves ₹10-20K.
Income above ₹30 lakh: At high incomes, the 25% surcharge in old regime vs 25% capped surcharge in new regime becomes a factor. New regime caps surcharge at 25% (for income above ₹2 crore), while old regime goes up to 37%. For ultra-high earners (₹5Cr+), new regime can save ₹30-50 lakh annually just from the surcharge cap. Always do detailed computation at this level.
📋Tax compliance calendar — never miss a deadline
June 15: First advance tax installment (15% of estimated annual tax). Only required if tax liability exceeds ₹10,000 after TDS. Relevant for freelancers, business owners, and employees with significant other income.
July 31: ITR filing deadline for individuals (no audit). Missing this incurs ₹5,000 penalty (₹1,000 if income is under ₹5L). More importantly, you lose the right to carry forward capital losses and business losses. Always file on time even if you can't pay the full tax — file first, pay later.
September 15: Second advance tax installment (cumulative 45%). Also the deadline for filing revised/belated return for the previous year (if original was filed on time). Check your Form 26AS for any TDS mismatches before this date.
March 15: Fourth and final advance tax installment (cumulative 100%). Also the last date to make tax-saving investments (80C, 80D, NPS) for the current financial year. After March 31, the window closes permanently for that year's deductions. Complete all tax planning by March 15 — don't wait until the last day.
