What Is AIS (Annual Information Statement) and Why You Should Check It Before Filing

What AIS actually is

The Annual Information Statement (AIS) is a detailed summary the Income Tax Department compiles against your PAN, covering salary, interest, dividends, securities and mutual fund transactions, tax payments, and more, for a specific financial year. Think of it as the department showing you what various banks, employers, brokers, and other institutions have already told them about your income and transactions, before you even start filling in your return.

You can download it from the e-filing portal under e-File > Income Tax Returns > View AIS, in three formats: a PDF for reading, a JSON file for import into the department's AIS Utility software, and a Taxpayer Information Summary (TIS) PDF, which is a more condensed category-level rollup of the same information.

How AIS differs from Form 26AS

Form 26AS is narrower. It's primarily built around tax deducted or collected at source (TDS/TCS), plus a record of your tax payments. If your bank didn't deduct TDS on a particular interest payment (because it was below a threshold, for instance), that interest might not show up in Form 26AS at all.

AIS casts a wider net. It also pulls in data reported through Statement of Financial Transactions (SFT), a separate reporting mechanism banks, registrars, and depositories use to tell the department about specific transactions, independent of whether TDS applied. This is why AIS can show, for example, savings account interest that never had any tax withheld on it, or mutual fund sale transactions from your demat account.

Why checking AIS before filing is worth the extra step

Two practical reasons stand out.

It can surface income you genuinely forgot about. Small, easy-to-overlook accounts, like an old fixed deposit with a non-bank finance company, a dormant savings account, or a joint account you don't actively use, routinely show up in AIS even when they've slipped your mind entirely. In practice, a small term deposit interest entry can appear in AIS that you have no memory of at all. Tracing it back to the reporting entity's name (visible in the detailed AIS PDF, not just the summary) is usually enough to confirm whether it's a genuine, forgotten deposit or a reporting error.

It lets you catch mismatches before the department does. If your return doesn't reflect income that AIS shows the department already knows about, that gap is exactly the kind of thing that can trigger a query or notice later. Reconciling proactively is far less stressful than responding to a department inquiry after the fact. This is one of the more common, avoidable causes behind the ITR filing mistakes that delay refunds or trigger notices.

What AIS does and doesn't guarantee

AIS is genuinely useful, but it isn't infallible, and it shouldn't be treated as complete or automatically correct.

• Reporting lags: a transaction near the end of the financial year might not have made it into AIS yet, even though it's real and settled. If you compare AIS against a broker's own tax P&L statement and find a gap, the broker's transaction-level records are usually the more reliable source for that specific gap, since AIS depends on the depository or registrar's own reporting timeline.
• No capital gains detail on cost basis: AIS may show that securities were sold, but the actual gain/loss computation, factoring in your cost of acquisition, holding period, and any exemptions, still needs to come from your own records or your broker's statement.
• Category-level ambiguity: the same interest can occasionally appear reported through more than one mechanism (once via a TDS-linked entry, once via SFT), which can look like double income if you're not reading the account numbers and dates carefully. When in doubt, verify the actual total against your bank's own interest certificate.

A simple habit worth adopting

Before filing, download the AIS PDF (not just the TIS summary) and specifically search for the income types you expect: interest, dividends, securities sales. Confirm each entry's reporting entity and amount against your own records. It takes a few extra minutes, and it's the single best way to catch both errors in the department's data and gaps in your own memory before they become a problem after you've already filed. If you're filing through a platform like Quicko, this is also worth doing before you trust its auto-imported figures at face value.
