Tax Saving Calculator — Maximize Your Deductions Under Old Regime — India 2026
Calculate total tax savings through Section 80C 80D 80E 80G NPS and other deductions. Find the optimal investment strategy to minimize income tax.
Tax saving in India revolves around strategic use of deduction sections under the old tax regime. Section 80C alone allows Rs 1.5 lakh deduction through multiple instruments. Adding 80D (health insurance) 80CCD1B (NPS) 80E (education loan interest) and HRA exemption can reduce your taxable income by Rs 4-6 lakh potentially saving Rs 1-2 lakh in taxes annually. The key is knowing which sections apply to you and maximizing each one.
How to save maximum tax under old regime?
Priority order: 1) EPF counts toward 80C automatically. 2) ELSS mutual fund for remaining 80C (best returns). 3) Health insurance for 80D (Rs 25K self + Rs 25-50K parents). 4) NPS for additional Rs 50K under 80CCD1B. 5) Home loan interest under Section 24 if applicable. 6) HRA exemption claim. This combination saves Rs 1-2 lakh in tax depending on your income slab.

How Tax Calculation Works
Income tax is calculated on your total taxable income after deducting eligible exemptions and deductions from your gross income. The tax is applied progressively — you pay a lower rate on initial income slabs and higher rates only on income that exceeds each threshold. This means moving into a "higher tax bracket" does not mean your entire income is taxed at the higher rate. Understanding marginal vs effective tax rate is crucial: your marginal rate applies only to the last rupee earned, while your effective rate is the average across all slabs.
Tax-Saving Strategies
Under the old regime, maximize deductions: Section 80C allows up to Rs 1.5 lakh through PPF, ELSS, EPF, and life insurance. Section 80D covers health insurance premiums up to Rs 25,000 (Rs 50,000 for senior citizens). Section 80CCD(1B) offers an additional Rs 50,000 deduction for NPS contributions. Home loan interest up to Rs 2 lakh is deductible under Section 24. Under the new regime, the Rs 75,000 standard deduction and lower slab rates may save you more if your total deductions are below Rs 3.75 lakh. Calculate under both regimes before choosing.

How to save maximum tax under old regime?

This combination saves Rs 1-2 lakh in tax depending on your income slab.
ELSS vs PPF vs NPS for tax saving?
ELSS: shortest lock-in (3 years) highest potential returns (12-15% CAGR) moderate risk. PPF: 15-year lock-in guaranteed returns (7.1%) zero risk tax-free maturity. NPS: locked until 60 mixed returns (8-10%) but additional Rs 50K deduction under 80CCD1B. Best strategy: use ELSS for 80C (returns + short lock-in) and NPS for additional 80CCD1B deduction.
Is tax saving worth it under new regime?
Under the new regime most deductions are not available so tax-saving investments serve no tax purpose. However the investments themselves remain excellent wealth-building tools. If you choose the new regime invest in ELSS PPF or NPS for their inherent returns not for tax saving. Compare total tax under both regimes before deciding.
Which tax regime should I choose — old or new?
Choose the new regime if your total deductions are below Rs 3.75 lakh. Choose the old regime if you claim HRA, 80C (Rs 1.5L), 80D, home loan interest, and NPS totaling more than Rs 3.75 lakh. Salaried employees can switch every year.
Is income up to Rs 12 lakh really tax-free?
Under the new regime for FY 2025-26, income up to Rs 12 lakh is effectively tax-free due to Section 87A rebate. After Rs 75,000 standard deduction, taxable income is Rs 11.25 lakh which qualifies for full rebate. However, income even slightly above Rs 12 lakh loses this entire benefit.
How can I save more tax legally?
Under the old regime, maximize 80C (Rs 1.5L via PPF, ELSS, EPF), 80D (Rs 25K-50K for health insurance), 80CCD(1B) (Rs 50K for NPS), HRA exemption, and home loan interest (Rs 2L under Section 24).
