Form 26AS
Form 26AS is the consolidated tax credit statement maintained by the Income Tax Department that reflects all TDS deducted, TCS collected, advance tax paid, and self-assessment tax paid against a taxpayer's PAN for a given financial year.
Form 26AS functions as a taxpayer's 'tax passbook' — a centralised record of all tax credits available to the taxpayer. It is generated and maintained by the Tax Information Network (TIN) operated by NSDL, and can be accessed through the income tax e-filing portal (incometax.gov.in) or through net banking portals of authorised banks. It is organised into multiple parts covering TDS on salary, TDS on other income, TCS, advance tax, refunds, and specified financial transactions.
For equity investors, the most relevant sections are those reflecting TDS on dividends (Section 194/195), TDS on interest income (Section 194A), and, for mutual fund investors, any TDS on capital gains distributions. The Specified Financial Transactions (SFT) section of Form 26AS also captures high-value transactions reported by banks, brokers, and mutual fund houses — including equity purchases and sales above threshold amounts — enabling the income tax department to cross-check ITR disclosures.
Form 26AS was significantly expanded by the Finance Act 2020, which added SFT data, pending income tax proceedings, and demand/refund information. However, it has been progressively supplemented by the more comprehensive Annual Information Statement (AIS) introduced in 2021, which captures transaction-level detail beyond what Form 26AS shows. Together, Form 26AS and AIS provide the two-layered pre-fill framework used by the income tax portal for ITR preparation.
Mismatches between Form 26AS and ITR filings are a common trigger for income tax notices. If a deductor has deposited TDS under the taxpayer's PAN but with an incorrect challan entry, it may not reflect correctly in Form 26AS. Investors must verify Form 26AS before filing and contact deductors (banks, companies, brokers) to correct errors through revised TDS returns filed by the deductor.
Form 26AS is available free of cost and can be downloaded in multiple formats. It is updated dynamically as deductors file quarterly TDS returns (typically by May 15, August 15, November 15, and February 15). For ITR filing due by July 31, investors should ideally wait until the Form 26AS for Q4 (January–March) is updated — which typically happens by early-to-mid May — to ensure completeness before reconciling with their income records.
