ITR FILING DEADLINE 2026 AY 2026–27: Are You Ready?

Documents Checklist for ITR Filing (AY 2026–27) – Detailed Guide

Filing your Income Tax Return (ITR) accurately requires collecting the right documents beforehand. Having these documents ready helps avoid mistakes, notices, delayed refunds, and mismatches in reported income.

Form 16 – Salary & TDS Certificate:

Salaried employees and pensioners receiving pensions through employers/banks (where applicable) are kind of taxpayers who require this. What does it contain, like gross salary received during the financial year, exemptions claimed (HRA, LTA, etc.), deductions under Chapter VI-A (80C, 80D, etc.), tax deducted at source (TDS), and net taxable income. Form 16 serves as the primary document for salaried taxpayers when filing ITR-1 or ITR-2. It helps ensure that salary income and TDS details are correctly reported.

Form 26AS – Tax Credit Statement:

Form 26AS is a consolidated tax statement available on the Income Tax Portal. It contains TDS deducted by employers, TDS deducted by banks, TCS (Tax Collected at Source), advance tax paid, self-assessment tax paid, and refund details. Before filing your return, match all TDS entries in Form 16 with Form 26AS. Any mismatch can result in Reduced tax credit, Tax demand notices and Refund delays

AIS (Annual Information Statement):

AIS provides a comprehensive view of a taxpayer’s financial transactions reported to the Income Tax Department. It may contain details of salary income, interest income, dividend income, securities transactions, mutual fund investments, property transactions, foreign remittances, and GST turnover (where applicable). The Income Tax Department uses AIS to cross-check information reported in your ITR. Omitting income appearing in AIS may trigger scrutiny or notices.

TIS (Taxpayer Information Summary)

TIS is a summarized version of AIS. Benefits are easier to understand than AIS, show categorized income details and help reconcile taxable income before filing. TIS provides a quick snapshot of information likely to be auto-populated in ITR forms.

PAN (Permanent Account Number):

PAN serves as the primary identifier for income tax purposes. Uses filing ITR, claiming refunds, matching tax credits, and tracking tax compliance. Ensure the PAN details match the information available on the Income Tax Portal.

Aadhaar Card 

Importance of Aadhaar: Required for PAN-Aadhaar linkage, used for e-verification of ITR, and helps in processing refunds and tax-related communications. Before filing, verify the Aadhaar number, Name and date of birth consistency and PAN-Aadhaar linkage status. Any mismatch can cause filing or verification issues.

Donation Receipts 

Applicable for taxpayers claiming deductions under Section 80G. Receipts should contain the name of the trust/institution, PAN of the institution (where applicable), registration number, donation amount, and date of donation. Without proper receipts, deduction claims may be disallowed during assessment.
