All the Important Rules for Income Tax in India
In India, income tax is governed by the Income Tax Act, 1961. A new Income Tax Act, 2025 is set to come into force from April 1, 2026. However, returns relating to FY 2025-26 (AY 2026-27) continue to be governed by the provisions of the Income Tax Act, 1961. These laws set the framework that applies to everyone, from salaried employees to freelancers, traders, and businesses.
Rule #1: Know the New Tax Regime Rules vs the Old Tax Regime Rules
India’s tax system underwent a major overhaul with the introduction of the new tax regime rules. The government now offers taxpayers the option to choose between…
- The Old Tax Regime, which lets you claim multiple deductions and exemptions like 80C, HRA, and standard deduction.
- The New Tax Regime, which offers lower tax slabs but without most deductions.
Here’s a quick peek at the new tax regime rules for FY 2025-26 (AY 2026-27)…
| Income Slab | Tax Rate |
|---|---|
| Up to INR 4 lakh | Nil |
| INR 4 lakh – INR 8 lakh | 5% |
| INR 8 lakh – INR 12 lakh | 10% |
| INR 12 lakh – INR 16 lakh | 15% |
| INR 16 lakh – INR 20 lakh | 20% |
| INR 20 lakh – INR 24 lakh | 25% |
| Above INR 24 lakh | 30% |
Here’s what’s hot in the new tax regime…
- Standard deduction of INR 75,000 (raised from INR 50,000)
- Section 87A rebate up to INR 60,000
- For salaried taxpayers, income up to INR 12.75 lakh may effectively become tax-free under the new tax regime due to the rebate and standard deduction
- You can still claim employer’s NPS (80CCD(2)) and Agniveer Fund (80CCH)
Tax Hack: Choose the new tax regime rules if you don’t invest heavily in deductions, but old regime if you want to claim exemptions. Salaried with zero deductions? New regime might be your bestie. Heavy investor in LIC, ELSS, home loan interest? Old regime is your jam.

Rule #2: Pick the Right ITR Form, It’s More Important Than You Think
One of the most important income tax return file rules is to pick the correct ITR form. Filing under the wrong form can lead to rejected returns or unwanted notices.
Here’s the lowdown on popular ITR forms…
- ITR-1 (Sahaj): For resident individuals having total income up to INR 50 lakh and eligible income sources, including salary/pension and income from up to two house properties, subject to prescribed conditions.
- ITR-2: For those with capital gains, foreign income, or multiple house properties.
- ITR-3: For business or profession income (including freelancers).
- ITR-4 (Sugam): For presumptive income under sections 44AD and 44ADA.
Remember, crypto investors and traders cannot file ITR-1 and usually have to file ITR-2 or ITR-3. This is a critical ITR rule many miss!

Rule #3: Always File Your Return Before the Deadline
Filing your ITR on time is a golden rule in the income tax return rules. The deadline for most taxpayers not requiring audit is July 31st following the financial year.
Here are the key ITR deadlines for FY 2025-26 (AY 2026-27)…
- July 31, 2026: For salaried individuals and investors filing ITR-1 or ITR-2
- August 31, 2026: For business and professional taxpayers filing ITR-3 or ITR-4 (non-audit cases)
- October 31, 2026: For taxpayers requiring audit
- December 31, 2026: Last date for belated returns
- March 31, 2027: Last date for revised returns
Miss these deadlines and you may face penalties under Section 234F. The late filing fee can be up to INR 5,000, subject to applicable provisions. Additionally, late filing may result in the loss of the ability to carry forward certain losses, such as business losses and capital losses.

Rule #4: Disclose All Your Income, It’s the Best Way to Avoid Trouble
The Indian income tax rules mandate that you must disclose all income earned during the financial year. This includes…
- Salary income
- Rental income
- Capital gains from stocks or property
- Income from transfer of Virtual Digital Assets (VDAs), including cryptocurrencies and NFTs, which is generally taxed at 30% under Section 115BBH

Rule #5: Claim Eligible Deductions (Old Tax Regime Only!)
Deductions reduce your taxable income, lowering your tax liability. But remember, income tax guidelines say deductions only apply under the old tax regime.
Popular deductions include…
- Section 80C (up to INR 1.5 lakh): PPF, ELSS, LIC, home loan principal, tuition fees
- Section 80D: Health insurance premiums
- Section 80CCD(1B): Additional INR 50,000 for NPS contributions
- Section 24(b): Home loan interest up to INR 2 lakh
- Section 80TTA/80TTB: Savings account interest (INR 10,000 for individuals, INR 50,000 for senior citizens)
Always keep documents handy to substantiate your claims during scrutiny, because the income tax return file rules are strict about documentation.

Rule #6: Freelancers, Traders, and Businesses Must Follow Special Income Tax Return Rules
If you earn through freelancing, trading, or business, the income tax return file rules are different and more detailed…

Filing your return is incomplete until you verify it electronically. Verification can be done via…
- Aadhaar OTP
- Net banking
- EVC (Electronic Verification Code) sent to your registered mobile or email
- Demat account verification
Failing to verify your return within the prescribed time limit may render it invalid and delay or prevent the processing of your refund. This is a vital income tax return file rule many taxpayers overlook.
Pro Tip: Using income tax software can simplify both filing and e-verification, ensuring you never miss critical steps.
Bonus: Keep Abreast of the New Income Tax Law ITR Updates FY 2026-27 (And Beyond!)
