Frequently Asked Questions
What is the difference between old and new tax regimes in India?
The Indian income tax system offers two parallel tax regimes. The old regime has higher tax rates but allows numerous deductions and exemptions such as HRA, Section 80C investments up to 1.5 lakh, Section 80D health insurance premiums, home loan interest under Section 24, and many others. The new regime introduced in 2020 and revised in 2023 offers significantly lower tax rates with more slabs but eliminates most deductions and exemptions. Under the new regime for FY 2024-25, income up to 3 lakh is tax-free, 3 to 7 lakh is taxed at 5 percent, 7 to 10 lakh at 10 percent, 10 to 12 lakh at 15 percent, 12 to 15 lakh at 20 percent, and above 15 lakh at 30 percent. A standard deduction of 75,000 is also available.
Which tax regime should I choose for maximum savings?
The choice between old and new regimes depends on the total value of deductions and exemptions you can claim. As a general rule, if your total deductions under the old regime exceed approximately 3.75 lakh to 4 lakh rupees, the old regime is likely more beneficial. If your deductions are below this threshold, the new regime with its lower slab rates will result in lower tax. Salaried employees with significant HRA exemption, home loan interest, and full 80C investments often benefit from the old regime. Employees without rent payments, home loans, or substantial investments typically benefit from the new regime. Indian Income Tax Calculator compares both regimes side by side so you can see the exact difference. You can switch between regimes each year if you have no business income.
How does health and education cess work in Indian income tax?
A health and education cess of 4 percent is levied on the total income tax amount including any applicable surcharge. For example, if your computed tax is 1 lakh rupees, the cess adds 4,000 rupees making the total 1,04,000 rupees. This cess funds the government's health and education initiatives and applies to all taxpayers regardless of income level or tax regime chosen. The cess cannot be claimed as a deduction.
What is surcharge on income tax and when does it apply?
Surcharge is an additional tax levied on taxpayers with higher income levels. For FY 2024-25 under the new regime, a 10 percent surcharge applies on income exceeding 50 lakh, 15 percent on income exceeding 1 crore, and 25 percent on income exceeding 2 crore. The maximum surcharge rate is capped at 25 percent under the new regime. Under the old regime, rates go up to 37 percent for income above 5 crore. Marginal relief ensures your total tax does not exceed the income above the surcharge threshold.
What is the EEE (Exempt-Exempt-Exempt) tax status?
EEE (Exempt-Exempt-Exempt) describes investments where your money is never taxed at any of the three stages. The first E means your contribution qualifies for a tax deduction (e.g., under Section 80C). The second E means the interest or growth earned is tax-free each year. The third E means the maturity or withdrawal amount is also fully tax-free. PPF enjoys full EEE status. EPF qualifies if the employee has been in continuous service for 5+ years and the withdrawal does not exceed ₹50 lakh. Sukanya Samriddhi Yojana and certain life insurance proceeds also have EEE status.
What are the tax benefits of NPS contributions?
NPS offers three layers of tax deduction. Under Section 80CCD(1), your own contributions qualify within the shared ₹1.5 lakh 80C ceiling. Section 80CCD(1B) provides an exclusive additional deduction of up to ₹50,000 — meaning a high-income taxpayer in the 30% bracket saves ₹15,000 in tax just from this extra window. Under Section 80CCD(2), employer contributions of up to 10% of basic salary (14% for central government employees) are deductible without any cap. At maturity, 60% of the corpus can be withdrawn tax-free; the remaining 40% must be used to buy an annuity, which is then taxed as regular income.
