Three documents confuse almost every first-time filer: Form 16 from the employer, Form 26AS for tax credits, and the Annual Information Statement (AIS) for third-party reporting. Each has a different job. Learning that job saves you from double-counting income, missing TDS credits, or ignoring lines the department already sees.
- Form 16 summarises employer-processed salary, exemptions, and salary TDS, not all your worldly income.
- 26AS is central for TDS/TCS credits; missing credits here can mean missing credit at assessment.
- AIS is a reconciliation aid; entries may need feedback or correction and are not always final taxable amounts.
- Use all three together with your own bank and broker statements for a filing-ready picture.
Part A of Form 16 links to TRACES and shows quarterly TDS deposited by your employer against your PAN. Part B summarises gross salary, perquisites, exemptions allowed in payroll, standard deduction, Chapter VI-A as processed, taxable income, and tax thereon.
It is excellent for salary, but it will not list interest on savings outside payroll, dividends, or capital gains from your broker unless your employer somehow routed them (rare). Treat Form 16 as the salary spine of your return, not the full skeleton.
Form 26AS aggregates tax deducted at source, tax collected at source, and certain other tax payments mapped to your PAN. Before you finish filing, you generally want salary TDS, bank TDS, and other credits to appear here.
If a legitimate credit is missing, follow up with the deductor and use the prescribed portal processes. Filing against a 26AS that you have not reviewed is a common source of demand notices later.
AIS pulls together information reported by banks, brokers, registrars, and other entities, interest, dividends, securities transactions, and more. Think of it as the department’s draft checklist of what the ecosystem reported about you.
Some lines are gross, some need classification (for example, which gain is capital gains), and occasional duplicates or errors require feedback. AIS supports transparency and E-E-A-T-style diligence: cross-check every material line against your own records before you certify your return.
SalTax writes for salaried taxpayers and professionals in India who want clear explanations, not jargon. Our guides reflect how tax compliance works in practice, including payroll, Form 16, AIS, and filing, but they are educational only. They are not tax, legal, or investment advice. Rules, limits, and forms change with each Finance Act and assessment year. Always confirm the current year on the official Income Tax Department website (incometax.gov.in) and use a Chartered Accountant or qualified tax adviser for your own return, notices, or planning.
