Form 26AS vs Form 16: what each one actually shows, and why they need to match

Form 16 and Form 26AS answer two different questions, not the same question twice. Form 16, from your employer, tells you what you were paid and what was deducted from your salary specifically. Form 26AS, from the tax department, tells you what has actually been credited against your PAN from any source, salary included but not limited to it. A third statement, the Annual Information Statement, covers what neither of these does: the income itself, beyond salary, that the department already knows about.

What each document actually contains

Form 16 is issued by your employer, generally around the start of the filing season, and it covers exactly one thing: your salary for the year and the tax deducted from it under Section 192. It says nothing about fixed deposit interest, dividends, rental income or capital gains, because your employer has no visibility into any of that.

Form 26AS is the tax department’s own record of tax credited against your PAN, TDS from any deductor, TCS, advance tax you paid yourself, self-assessment tax, refunds issued. It is broader than Form 16 in one specific way, it covers tax from every source, not just your employer, but it still only shows tax already paid, not your income generally.

The Annual Information Statement, AIS, is the one that actually covers income beyond salary: savings account and fixed deposit interest, dividends, rent received, capital gains, and a range of higher-value transactions such as large cash deposits, significant credit card spending, and property purchases. A summarised, de-duplicated version of it, the Taxpayer Information Summary or TIS, is what actually pre-fills your return, not the raw AIS entries themselves.

Why the department now expects all three to agree

For years, Form 26AS alone was treated as the reference point before filing. That stopped being sufficient once AIS started capturing income the older statement never touched. A return that matches Form 26AS perfectly can still draw a mismatch notice today if it ignores fixed deposit interest or rental income that AIS already has on record. Matching your return against all three, not just checking your TDS against Form 26AS, is what actually avoids the notice now.

A common mismatch, and why it usually is not an error

Say your Form 16 shows 48,000 rupees of TDS deducted across the year, but Form 26AS currently shows only 36,000 rupees. The likely explanation is not that money went missing, it is that your employer deducted the tax correctly through the year but had not yet filed the quarterly TDS return covering the final quarter’s salary at the time you checked. Once that return is filed and processed, the remaining amount typically appears in Form 26AS within a couple of weeks. Holding off on filing until the figures reconcile, and following up with your employer’s payroll or HR team if the gap persists, is the practical response, rather than filing on the Form 16 figure and hoping the credit sorts itself out.

What people get wrong about this

Assuming Form 26AS shows all your income. It does not, and never has. It shows tax credited, not income earned. Interest, dividends and capital gains have to be checked against AIS instead.

Claiming a TDS credit based on Form 16 alone when Form 26AS shows less. The credit you can actually claim generally follows Form 26AS, not Form 16. A mismatch is worth resolving with the deductor before filing, since claiming the higher figure regardless tends to invite a notice rather than avoid one. If a mismatch has already turned into a tax demand, the TDS mismatch checker walks through getting it rectified.

Treating a Form 26AS and Form 16 match as the whole reconciliation job. It covers salary and its TDS. It says nothing about whether your interest income, dividends or rental income are correctly declared, that check happens against AIS separately.

Ignoring AIS entries because they look unfamiliar. An unfamiliar entry is more often a transaction you genuinely forgot, like interest on an old account, than an error in the system. Check it against your own records before dismissing it, and use the feedback option in AIS if it is genuinely wrong or duplicated.
