What Is Income Tax E-Filing?

Income tax e-filing means submitting your Income Tax Return (ITR) online through the Income Tax Department’s official portal (incometax.gov.in). Instead of visiting a tax office and filling paper forms, you do everything digitally — from entering your income details to uploading documents and getting your refund.

The Government of India made e-filing mandatory for most taxpayers years ago, and today it is the fastest, safest, and most convenient way to stay compliant with your tax obligations.

Who Must File an Income Tax Return?

This is one of the most searched questions around tax season. Here is the simple answer:

You must file an ITR if:

  • Your total income exceeds ₹2.5 lakh per year (₹3 lakh for senior citizens, ₹5 lakh for super senior citizens aged 80+)
  • You are a company or firm — regardless of profit or loss
  • You want to claim a tax refund
  • You have foreign assets or foreign income
  • You deposited more than ₹1 crore in a bank account during the year
  • You spent more than ₹2 lakh on foreign travel
  • You paid more than ₹1 lakh in electricity bills

Even if your income is below the taxable limit, filing a return is strongly recommended. It helps you get loans, apply for visas, and build a clean financial record.


Due Dates for ITR Filing — AY 2026-27

Missing the deadline attracts a late filing fee under Section 234F. Here are the key dates:

Category of TaxpayerDue Date
1. Individuals, HUF, AOP (no audit required)31st July 2026
2. Businesses requiring tax audit31st October 2026
3. Companies31st October 2026
4. Transfer Pricing cases30th November 2026

Filing after the due date? You can still file a belated return up to 31st December 2026, but you will pay a late fee of up to ₹5,000 (₹1,000 if income is below ₹5 lakh).

Which ITR Form Should You Use?

Choosing the wrong form is a common mistake. Here is a quick guide:

ITR-1 (Sahaj): For salaried individuals, pensioners, and those with income from one house property and interest income. Total income must be below ₹50 lakh.

ITR-2: For individuals and HUFs with capital gains, foreign income, or more than one house property.

ITR-3: For professionals, freelancers, and partners in a firm with business or professional income.

ITR-4 (Sugam): For individuals, HUFs, and firms opting for the presumptive taxation scheme (Section 44AD/44ADA/44AE).

ITR-5: For LLPs, partnership firms, AOPs, and BOIs.

ITR-6: For companies other than those claiming exemption under Section 11.

ITR-7: For trusts, NGOs, political parties, and research institutions.

If you run a sole proprietorship business in India, you file under ITR-3 or ITR-4 using your PAN. If you have registered as a Pvt Ltd company in India, you file ITR-6.

Documents Required for Income Tax E-Filing

Keep these documents ready before you start:

  • PAN card and Aadhaar card
  • Form 16 (from your employer) or Form 16A/16B for TDS on other income
  • Bank account statements for all accounts
  • Interest certificates from banks and post offices
  • Home loan interest certificate (if applicable)
  • Investment proofs for Section 80C, 80D, 80G deductions (LIC, PPF, ELSS, health insurance, donations)
  • Capital gains statements from brokers (for mutual funds and stocks)
  • Rent receipts and landlord’s PAN (if claiming HRA)
  • Foreign income or asset details (if applicable)
  • Previous year’s ITR acknowledgement (useful for carry-forward losses)

Step-by-Step: How to File Income Tax Return Online

Step 1 — Register or Login

Go to incometax.gov.in and log in with your PAN. If you are a new user, register first using your PAN, Aadhaar, and mobile number.

Step 2 — Select the Assessment Year

Choose AY 2026-27 (for income earned from April 2025 to March 2026).

Step 3 — Choose the Filing Mode

Select “Online” mode for simple returns. For complex returns involving business income or capital gains, use offline mode by downloading the utility.

Step 4 — Select the Correct ITR Form

Based on your income sources (see the table above), pick the right form.

Step 5 — Pre-fill and Verify Your Data

The portal automatically pre-fills data from your Form 26AS, AIS (Annual Information Statement), and TIS (Taxpayer Information Summary). Cross-check all figures carefully.

Step 6 — Enter Your Income Details

Fill in income from salary, house property, business/profession, capital gains, and other sources.

Step 7 — Claim Deductions

Enter deductions under Chapter VI-A — Section 80C (investments up to ₹1.5 lakh), 80D (health insurance), 80G (donations), and so on.

Step 8 — Compute Tax and Pay Self-Assessment Tax

If any tax is due after TDS credits, pay it online using Challan 280 before submitting the return.

Step 9 — Submit and E-Verify

Submit your return. Then verify it within 30 days using:

  • Aadhaar OTP (easiest method)
  • Net banking
  • Bank account EVC
  • Demat account EVC
  • Sending a signed ITR-V to CPC Bengaluru (physical method)

Verification is mandatory. An unverified return is considered not filed.

Income Tax Return Filing for Different Entities

Individuals

Salaried employees, freelancers, and self-employed professionals all need to file based on their income. We offer expert-assisted income tax return filing for salaried and self-employed individuals at affordable fees.

Sole Proprietorship

A sole proprietor files under their personal PAN. The business income is included in the personal return. Get help with ITR filing for proprietorship businesses with all deductions to ensure all business expenses are correctly claimed.

Companies and LLPs

Companies must file ITR-6 and LLPs file ITR-5. Both need a tax audit if turnover crosses ₹1 crore (businesses) or ₹50 lakh (professionals). Companies also need to complete their annual ROC compliance for private limited companies alongside ITR filing.

NGOs and Trusts

Registered NGOs with 12A tax exemption registration for NGOs and 80G donation tax deduction registration enjoy income tax exemptions, but they must still file their return using ITR-7. We provide specialised income tax return filing for trusts and non-profit organisations.

Income Tax Audit — When Is It Mandatory?

A tax audit under Section 44AB is required when:

  • Business turnover exceeds ₹1 crore (or ₹10 crore if cash transactions are below 5%)
  • Professional receipts exceed ₹50 lakh
  • You opt out of presumptive taxation and your income is above the basic exemption limit

Our qualified Chartered Accountants handle Section 44AB income tax audit for businesses and professionals efficiently, ensuring full compliance without last-minute stress.
