Individual Income Tax in India Explained Simply

Individual income tax in India is charged on the income you earn in a financial year, and you report it by filing an Income Tax Return (ITR). Your tax depends on your income, which tax regime you choose, and the deductions you claim where your regime allows them. This guide explains the basics in plain language: how slabs work, how to file, which deductions commonly matter, and what freelancers should know.

Tax rules in India are updated regularly, often in the Union Budget. Slab rates, limits and regime details change, so use this article to understand the concepts and check the current figures on the official income tax website before you file. Note too that the Income-tax Act, 2025 replaced the Income-tax Act, 1961 from 1 April 2026, so many sections have new numbers. This guide uses the familiar older names, such as Section 80C (now Section 123), and the underlying ideas are largely the same.

How income tax slabs work

India taxes individuals using slabs. Your income is divided into bands, and each band is taxed at its own rate. Only the income that falls inside a band is taxed at that band’s rate. Crossing into a higher slab does not mean your whole income is taxed at the higher rate.

Example with made-up numbers: assume the first 3 lakh is taxed at 0%, the next 3 lakh at 5% and the next 3 lakh at 10%. On an income of 8 lakh, you would pay nothing on the first 3 lakh, 5% of 3 lakh (15,000) on the next band, and 10% of 2 lakh (20,000) on the remaining part, giving 35,000 before any cess or rebate. Real slabs and rebates differ, so use the current ones.

Old regime versus new regime

Individuals can usually choose between two tax regimes. In broad terms:

• The old regime has higher rates but allows many deductions and exemptions, such as Section 80C and 80D.
• The new regime has lower slab rates but allows far fewer deductions.

Which one is better depends on how much you can genuinely claim. If you have large home loan interest, insurance premiums and investments that qualify, the old regime may come out cheaper. If you claim little, the new regime often does. Run both calculations each year, because the rules and default regime have changed over time.

Filing your ITR

An ITR is the form on which you report income and deductions for the year. Most people file online on the income tax department portal. The steps are generally:

1. Collect documents. Typical items are Form 16 from your employer, bank interest certificates, your tax statement (Form 26AS or the Annual Information Statement), investment proofs and rent or home loan details.
2. Choose the right form. ITR-1 is generally for salaried individuals with simple income. ITR-3 is for people with business or professional income, and ITR-4 is for those using the presumptive taxation scheme. Eligibility conditions apply, so check them.
3. Check your pre-filled data. The portal fills in some details. Compare them with your own records.
4. Report all income. This includes salary, interest, rent, capital gains and freelance earnings.
5. Pay any tax due. Use the portal to pay and file.
6. Verify the return. A return is not complete until you verify it, for example through Aadhaar OTP or net banking.

Filing on time matters. Late filing can lead to fees and may affect your ability to carry forward some losses. Many people can file without a chartered accountant, though complex situations such as business income or foreign assets are worth professional help.

Deductions that commonly matter

These mostly apply under the old regime. Limits change, so confirm the current figure.

• Section 80C: covers investments and payments such as EPF, PPF, ELSS mutual funds, life insurance premiums and tuition fees, up to an overall annual limit (1.5 lakh at the time of writing, so check the current figure).
• Section 80D: covers health insurance premiums for you and your family, and sometimes for parents, with separate limits.
• Home loan interest: interest on a loan for a house you live in or let out can be deductible, within limits, under the income from house property rules.
• Standard deduction: salaried individuals get a flat deduction from salary income without needing proof. It is available under the new regime too, though the amount can differ.

Example with round numbers: if your taxable income is 10 lakh and you invest 1.5 lakh in an eligible 80C option under the old regime, your taxable income falls to 8.5 lakh. If your top slab rate is 20%, that saves about 30,000 in tax (1.5 lakh x 20%), plus cess. Do not invest just for the deduction if the product does not suit you. Tax saving is a bonus, not a reason in itself.

Freelancers and side hustlers

If you earn from freelancing, consulting or gigs, you are generally treated as having business or professional income rather than salary. That changes a few things.

• Claim genuine expenses. Costs such as software, internet, equipment and professional fees can reduce your taxable profit, if you can document them.
• Advance tax. If your estimated tax liability for the year is above the threshold (generally 10,000 after TDS), you may need to pay tax in instalments through the year instead of in one go at filing time.
• Presumptive taxation. Some small businesses and professionals can opt for a simplified scheme that taxes a fixed percentage of receipts, with less need for detailed books. Eligibility limits apply.
• Keep books. Even a simple sheet of income and expenses saves stress when filing. Keep invoices and bank statements.
• TDS. Clients may deduct tax at source before paying you. The deducted amount is credited to you and shown in your tax statement, so make sure it matches.

Mistakes to avoid

• Forgetting to report interest income or a side income
• Not checking the tax statement before filing, which can lead to missed TDS credit or a mismatch notice
• Missing the filing deadline
• Claiming deductions without proof
• Not comparing both tax regimes
• Ignoring refunds: if too much tax was deducted, a correct return is how you claim the money back
