Income Tax Return Filing 2026: 10 Important Things First-Time Taxpayers Must Know Before Filing ITR

The Income Tax Department has enabled the Excel utilities and online filing forms for ITR-1 (Sahaj), ITR-2, ITR-3, ITR-4 (Sugam), ITR-5 and ITR-7 for AssesSMEnt Year (AY) 2026-27, corresponding to Financial Year (FY) 2025-26. The Excel utility allows taxpayers to prepare their returns offline before uploading them through the e-filing portal.

With the due date for filing Income Tax Returns extended to August 31, 2026, first-time taxpayers have sufficient time to complete the process. However, filing early can help avoid last-minute technical issues, calculation errors and delays in processing refunds.

Here are 10 important points every first-time taxpayer should know before filing an Income Tax Return (ITR).

1. Check Whether You Are Required to File an ITR

Apart from individuals whose taxable income exceeds the prescribed exemption limit, filing an ITR may also be mandatory in several other cases. Taxpayers may need to file returns if they own assets in India or abroad, invest in shares, ESOPs or other securities, maintain Bank deposits exceeding Rs 50 lakh, have savings or current account balances above Rs 1 crore, pay electricity bills exceeding Rs 1 lakh annually, incur overseas travel expenses of more than Rs 2 lakh or report sales exceeding Rs 60 lakh, irrespective of taxable income.

2. Understand Your Taxable Income

Taxable income is calculated after deducting eligible exemptions and deductions from your gross income. Your total earnings may include salary, interest from bank deposits, Dividends, capital gains and other income sources. Eligible deductions under various provisions, including investments in PPF, NPS, insurance premiums, home loan interest and certain rent-related benefits, can reduce your taxable income.

3. Choose Between the Old and New Tax Regime

Selecting the right tax regime is an important step while filing your return. The old regime offers several deductions and exemptions, while the new regime provides lower tax rates with limited deductions. Taxpayers should compare their tax liability under both regimes using online tax calculators or seek professional advice before making a choice.

4. Know the Filing Deadline

For AY 2026-27, the due date to file an Income Tax Return without penalty is August 31, 2026.

Taxpayers who miss the deadline can still file a belated return up to December 31, 2026, although a late filing fee ranging from Rs 1,000 to Rs 10,000 may apply depending on the delay and taxable income. Interest on unpaid tax liability may also be payable.

5. Keep All Required Documents Ready

Before starting the filing process, taxpayers should keep all necessary documents readily available. These generally include PAN, Aadhaar (linked with PAN), Form 16 issued by the employer, investment proofs, bank statements, PPF contribution details, insurance premium receipts and home loan interest certificates, wherever applicable.

6. Understand Form 16 and Form 26AS

Form 16 is issued by an employer and contains details of salary paid, tax deducted at source (TDS), exemptions and deductions claimed during the financial year.

Taxpayers should also verify Form 26AS and the Annual Information Statement (AIS), which provide a consolidated record of TDS, interest income, dividend income, securities transactions, foreign remittances and other financial information. Matching these details with the ITR helps avoid discrepancies.

7. Complete E-Verification After Filing

Filing the return alone does not complete the process. Taxpayers must verify their ITR within 30 days of submission. E-verification can be completed through Aadhaar OTP, net banking or an Electronic Verification Code (EVC). Failure to verify the return within the prescribed timeline may result in the return being treated as invalid, delaying any eligible refund.

8. Offline Verification Is Also Available

Taxpayers who cannot complete e-verification may opt for manual verification. This requires sending the signed ITR-V acknowledgement to the Centralized Processing Center (CPC) of the Income Tax Department in Bengaluru within the prescribed timeline.

9. Select the Correct ITR Form

Choosing the correct ITR form is essential for successful filing.

• ITR-1 (Sahaj): For individuals earning income from salary, one house property and other sources.
• ITR-2: For individuals and Hindu Undivided Families (HUFs) without business or professional income.
• ITR-3: For individuals and HUFs having income from business or profession.
• ITR-4 (Sugam): For taxpayers opting for the presumptive taxation scheme.

Taxpayers who are unsure about the applicable form can use the "Help Me Decide" option available on the Income Tax Department's e-filing portal to identify the correct return form based on their eligibility.

10. Missed Earlier Returns? ITR-U Can Help

Taxpayers who failed to file returns for any of the previous four assessment years may be eligible to submit an updated return using ITR-U, subject to the applicable provisions.

For the current assessment year, taxpayers should file their regular ITR within the due date. Missing the deadline may lead to late filing fees of up to Rs 5,000, along with applicable interest on outstanding tax liability.

Filing an Income Tax Return for the first time can seem overwhelming, but keeping the necessary documents ready, selecting the correct ITR form, verifying income details through Form 16 and AIS, and completing timely verification can make the process smooth. Filing before the due date also reduces the chances of technical issues and ensures quicker processing of refunds.
